DETAILED DESCRIPTION

0050According to various embodiments, the present invention is directed to a headband assembly that can be used with personal speakers and worn, for example, on the head of a human user. Referring primarily to <figref idref="DRAWINGS">FIGS. 1-3</figref>, a headband assembly <b>22</b> can include a spring band <b>30</b>, a sleeve or attachment portion <b>40</b><i>a</i>, and an extension arm <b>60</b><i>a</i>. As described herein, the sleeve <b>40</b><i>a </i>can be attached to an end of the spring band <b>30</b>, and the extension arm <b>60</b><i>a </i>can be moveably secured to a sleeve <b>40</b><i>a</i>. In various embodiments, the headband assembly <b>22</b> can include a single spring band <b>30</b>, two sleeves <b>40</b><i>a</i>, <b>40</b><i>b</i>, and two extension arms <b>60</b><i>a</i>, <b>60</b><i>b</i>, for example. The first sleeve <b>40</b><i>a </i>can be attached to a first end <b>32</b> of the spring band <b>30</b> and the second sleeve <b>40</b><i>b </i>can be attached to a second end <b>34</b> of the spring band. Furthermore, the first extension arm <b>60</b><i>a </i>can be moveably secured to the first sleeve <b>40</b><i>a </i>and the second extension arm <b>60</b><i>b </i>can be moveably secured to the second sleeve <b>40</b><i>b</i>. A component on a first side of the headband assembly may have a corresponding or identical component on a second side of the headband assembly <b>22</b>. In other words, the components of the headband assembly <b>22</b> can be modular. For example, the first sleeve <b>40</b><i>a </i>can be interchangeable with the second sleeve <b>40</b><i>b </i>and the first arm <b>60</b><i>a </i>can be interchangeable with the second arm <b>60</b><i>b</i>. Accordingly, throughout this Detailed Description, elements and/or characteristics of a component on a first side or a second side of the headband assembly <b>22</b> may be described and, unless otherwise indicated, such description is intended to apply to the corresponding or identical component on the other side of the headband assembly <b>22</b>, as well.

0051In various embodiments, the headband assembly <b>22</b> can be positioned relative to a user's head and/or neck. For example, the headband assembly <b>22</b> can fit around the top and/or the crown of a user's head, and/or around the back and/or nape of a user's neck. A pair of personal speakers, such as earphones <b>100</b><i>a</i>, <b>100</b><i>b </i>(<figref idref="DRAWINGS">FIGS. 21 &amp; 22</figref>) may be attached to the headband assembly <b>22</b>. The headband assembly <b>22</b> can hold the earphones <b>100</b><i>a</i>, <b>100</b><i>b </i>relative to the user's head and/or neck, and specifically relative to the user's ears such that the earphones <b>100</b><i>a</i>, <b>100</b><i>b </i>are in, over, and/or around the user's ears, for example. The headband assembly <b>22</b> can be adapted for use with various sizes and styles of earphones <b>100</b><i>a</i>, <b>100</b><i>b</i>, for example.

0052Referring now to <figref idref="DRAWINGS">FIG. 4</figref>, the spring band <b>30</b> can be contoured or arced. Furthermore, the spring band <b>30</b> can have a spring constant such that the deformation of the spring band <b>30</b> from an initial configuration to a deformed configuration can result in a springback or restoring force. In various embodiments, the spring band <b>30</b> can be deformed from the initial configuration to the deformed configuration when the spring band <b>30</b> is positioned relative to the user's head and/or neck. For example, the spring band <b>30</b> can be deformed to a less contoured or less arced configuration when positioned relative to the user's head and/or neck. Consequently, the spring band <b>30</b> can exert a springback force on the user's head and/or neck as the spring band <b>30</b> seeks to return or to substantially return to its initial configuration. Such a springback force can help to secure the spring band <b>30</b>, and ultimately the entire headband assembly <b>22</b>, in place relative to the user's head and/or neck. Furthermore, in some embodiments, the spring band can generate a springback or restoring force of approximately 1.25 lb when positioned relative to the user's head and/or neck. In at least one embodiment, the spring band <b>30</b> can generate a springback or restoring force of approximately 0.75 lb to approximately 2.0 lb when positioned relative to the user's head and/or neck.

0053The spring constant of the spring band <b>30</b> can at least depend on the dimensions and material thereof. In at least one embodiment, the spring band <b>30</b> can be approximately 5.3 inches by approximately 0.75 inches by approximately 0.03 inches with an initial, undeformed radius of curvature of approximately 3.3 inches. In various embodiments, the dimensions of the spring band <b>30</b>, including the radius of curvature, can be selected such that the spring band <b>30</b> comfortably fits the user's head and/or neck. Additionally, the dimensions of the spring band <b>30</b> can be selected such that the spring band <b>30</b> smoothly interfaces with the other headband assembly <b>22</b> components such as the sleeve <b>40</b><i>a</i>, for example. In at least one embodiment, the spring band <b>30</b> can comprise stainless steel, for example. In various embodiments, the spring band <b>30</b> can comprise metallic and/or polymeric materials, for example, such as nylon and/or acrylonitrile butadiene styrene (ABS), for example.

0054Referring still to <figref idref="DRAWINGS">FIG. 4</figref>, the spring band <b>30</b> can include the first distal end <b>32</b> and the second distal end <b>34</b>. As described herein, the first distal end <b>32</b> and/or the second distal end <b>34</b> of the spring band <b>30</b> can be positioned in and/or disposed through a portion of one of the sleeves <b>40</b><i>a</i>, <b>40</b><i>b </i>such that the sleeve <b>40</b><i>a</i>, <b>40</b><i>b </i>is attached to the spring band <b>30</b> at or near the respective distal end <b>32</b>, <b>34</b> thereof. The spring band <b>30</b> can include a pronged portion <b>36</b> extending from a distal end <b>32</b>, <b>34</b> along a portion of the spring band <b>36</b>. Still referring to <figref idref="DRAWINGS">FIG. 4</figref>, the spring band <b>30</b> can include the pronged portion <b>36</b> extending from the first distal end <b>32</b> and the pronged portion <b>36</b> extending from the second distal end <b>34</b>. The pronged portion <b>36</b> can be defined by a slot <b>37</b> that extends from the respective distal end <b>32</b>, <b>34</b> through a portion of the spring band <b>30</b>, such as 1.0 inch or 20% of the length of the spring band <b>30</b>, for example. The pronged portion <b>36</b> can taper as the pronged portion <b>36</b> approaches the respective distal end <b>32</b>, <b>34</b>, for example. In various embodiments, the pronged portion <b>36</b> can be deformable. For example, the prongs of the pronged portion <b>36</b> can move towards each other and the width of the slot can be reduced to compress or narrow the width of the pronged portion <b>36</b> of the spring band <b>30</b>. When the pronged portion <b>36</b> is deformed, the spring band <b>30</b> can exert a springback or restoring force as it seeks to return or substantially return to its initial configuration. As described herein, such a springback force generated by the pronged portion <b>36</b> can help to secure the spring band <b>30</b> to the sleeve <b>40</b><i>a</i>, <b>40</b><i>b </i>positioned relative thereto. In various embodiments, the spring band <b>30</b> can include additional slots and/or prongs, for example. In other embodiments, the spring band <b>30</b> may not include a slot and/or prongs, but may have other features or geometries that provide springback when a portion of the spring band <b>30</b> is deformed or compressed.

0055Still referring primarily to <figref idref="DRAWINGS">FIG. 4</figref>, the spring band <b>30</b> can include tabs <b>38</b><i>a</i>, <b>38</b><i>b</i>, <b>39</b><i>a</i>, <b>39</b><i>b </i>designed to help secure the spring band <b>30</b> to the first sleeve <b>40</b><i>a </i>and/or the second sleeve <b>40</b><i>b</i>. In various embodiments, the tabs <b>38</b><i>a</i>, <b>38</b><i>b</i>, <b>39</b><i>a</i>, <b>39</b><i>b </i>can be laterally opposed tabs. For example, a tab <b>38</b><i>a</i>, <b>38</b><i>b</i>, <b>39</b><i>a</i>, <b>39</b><i>b </i>can extend from a first lateral side of the spring band <b>30</b> in a first direction and a corresponding tab <b>38</b><i>a</i>, <b>38</b><i>b</i>, <b>39</b><i>a</i>, <b>39</b><i>b </i>can extend from an opposite lateral side of the spring band <b>30</b> in a second direction. In some embodiments, the second direction can be substantially opposite to the first direction. Referring still to <figref idref="DRAWINGS">FIG. 4</figref>, the first side of the spring band <b>30</b> can include two pairs of opposing tabs <b>38</b><i>a</i>, <b>39</b><i>a</i>, for example, and the second side of the spring band <b>30</b> can include two additional pairs of opposing tabs <b>38</b><i>b</i>, <b>39</b><i>b</i>, for example. A first pair of opposing tabs <b>38</b><i>a </i>can be positioned near or at the first distal end <b>32</b> and/or a second pair of opposing tabs <b>39</b><i>a </i>can be positioned farther from first distal end <b>32</b> such as, for example, past the slot of the pronged portion <b>36</b>. Furthermore, the spring band <b>30</b> can include a third pair of opposing tabs <b>38</b><i>b </i>near or at the second distal end <b>34</b> and/or a fourth pair of opposing tabs <b>39</b><i>b </i>farther from second distal end <b>34</b> such as, for example, past the slot of the pronged portion <b>36</b>. In other words, the spring band <b>30</b> can have two pairs of opposing tabs <b>38</b><i>a</i>, <b>39</b><i>a </i>near or around the first distal end <b>32</b> and two more pairs of opposing tabs <b>38</b><i>b</i>, <b>39</b><i>b </i>near or around the second distal end <b>34</b>. Further, in various embodiments, the tabs <b>38</b><i>a</i>, <b>39</b><i>a </i>on the first side of the spring band <b>30</b> can form a mirror image reflection of the tabs <b>38</b><i>b</i>, <b>39</b><i>b </i>on the second side of the spring band <b>30</b>. As described herein, when the sleeve <b>40</b><i>a </i>is positioned relative to the first end <b>32</b> of the spring band <b>30</b>, the tabs <b>38</b><i>a</i>, <b>39</b><i>a </i>of the spring band <b>30</b> can engage the sleeve <b>40</b><i>a </i>to help secure the sleeve <b>40</b><i>a </i>to the spring band <b>30</b>.

0056Referring primarily to <figref idref="DRAWINGS">FIGS. 5-8</figref>, the sleeve or attachment portion <b>40</b><i>a </i>can have a contoured or arced body that is configured for receiving a portion of the spring band <b>30</b>. The contour of the sleeve <b>40</b><i>a </i>can be selected such that the sleeve <b>40</b><i>a </i>comfortably fits on and/or around a portion of the user's head and/or neck, for example. Furthermore, as described herein, the sleeve <b>40</b><i>a </i>can be designed to releasably attach to the spring band <b>30</b> (<figref idref="DRAWINGS">FIG. 4</figref>) and to adjustably hold and retain the extension arm <b>60</b><i>a </i>(FIGS. <b>7</b> &amp; <b>12</b>-<b>14</b>). The sleeve <b>40</b><i>a </i>can include a slot <b>42</b> for receiving a portion of the spring band <b>30</b> (<figref idref="DRAWINGS">FIGS. 1-4</figref>) therein. The slot <b>42</b> can extend through a portion of the sleeve <b>40</b><i>a </i>to an opening <b>50</b>. In various embodiments, the opening <b>50</b> can include a groove or notch <b>51</b> (<figref idref="DRAWINGS">FIGS. 6 &amp; 8</figref>) therein. Referring again to <figref idref="DRAWINGS">FIGS. 1-3</figref>, when the first end <b>32</b> of the spring band <b>30</b> is positioned relative to the sleeve <b>40</b><i>a</i>, the first end <b>32</b> of the spring band <b>30</b> can extend through the slot <b>42</b> such that an end portion of the spring band <b>30</b> is disposed in the sleeve <b>40</b><i>a</i>. Further, the groove <b>51</b> of the opening <b>50</b> can hold the first distal end <b>32</b> of the spring band <b>30</b>. In other embodiments, the first end <b>32</b> of the spring band <b>30</b> may be held within the slot <b>42</b> of the sleeve <b>40</b><i>a</i>, for example.

0057In various embodiments, the spring band <b>30</b> and the sleeve <b>40</b><i>a </i>can form a snap-fit connection. For example, referring primarily to <figref idref="DRAWINGS">FIG. 2</figref>, the pronged portion <b>36</b> of the spring band <b>30</b> can be narrowed or compressed to fit through the slot <b>42</b> of the sleeve <b>40</b><i>a</i>. In various embodiments, the opposing tabs <b>38</b><i>a </i>nearest the first distal end <b>32</b> should also fit through the slot <b>42</b> when the pronged portion <b>36</b> is narrowed or compressed. When the pronged portion <b>36</b> is compressed, the pronged portion <b>36</b> can exert a springback force on the sleeve <b>40</b><i>a </i>in which the pronged portion <b>36</b> is retained as the pronged portion <b>36</b> seeks to return or substantially return to its undeformed configuration. Opposing tabs <b>38</b><i>a </i>can be positioned in the opening <b>50</b> and can engage the sleeve <b>40</b><i>a </i>as the pronged portion <b>36</b> seeks to return to its undeformed configuration. The springback force can cause the opposing tabs <b>38</b><i>a </i>that are positioned in the opening <b>50</b> to catch the sleeve <b>40</b><i>a</i>, which can restrict detachment of the sleeve <b>40</b><i>a </i>from the spring band <b>30</b>. For example, the opposing tabs <b>38</b><i>a </i>can catch the sleeve <b>40</b><i>a </i>such that the pronged portion <b>36</b> cannot be withdrawn through the slot <b>42</b>. Furthermore, the opposing tabs <b>39</b><i>a </i>that are positioned outside of the sleeve <b>40</b><i>a </i>(<figref idref="DRAWINGS">FIGS. 1 &amp; 3</figref>) can prevent over-insertion of the spring band <b>30</b> into the sleeve <b>40</b><i>a</i>. For example, the opposing tabs <b>39</b><i>a </i>can catch the sleeve <b>40</b><i>a </i>if the first end <b>32</b> of the spring band <b>30</b> attempts to over-advance through the slot <b>42</b>. In other words, the opposing tabs <b>38</b><i>a</i>, <b>39</b><i>a </i>can releasably lock the spring band <b>30</b> in position within the sleeve <b>40</b><i>a </i>and can prevent unintended retraction and/or over-insertion.

0058Referring again to <figref idref="DRAWINGS">FIGS. 1-3</figref>, the sleeve <b>40</b><i>a </i>can releasably attach to the spring band <b>30</b>. In other words, the sleeve <b>40</b><i>a </i>may be selectively detached from the spring band <b>30</b>. For example, the pronged portion <b>36</b> of the spring band <b>30</b> can be compressed or squeezed to move the prongs inward such that the tabs <b>38</b><i>a </i>disengage the sleeve <b>40</b><i>a </i>and permit the pronged portion <b>36</b>, including the opposing tabs <b>38</b><i>a</i>, to be withdrawn through the sleeve <b>40</b><i>a</i>. For example, the pronged portion <b>36</b> positioned in the opening <b>50</b> can be manually pinched and/or manipulated to release the spring band <b>30</b> from the sleeve <b>40</b><i>a. </i>

0059Referring again to <figref idref="DRAWINGS">FIGS. 5</figref>, <b>7</b>-<b>8</b>, the sleeve <b>40</b><i>a </i>can include an opposing detent arrangement <b>44</b>. The opposing detent arrangement <b>44</b> can include a group of one or more detent pockets <b>48</b> on a first internal side of the sleeve <b>40</b><i>a </i>and an opposing group of one or detent pocket <b>48</b> on a second internal side of the sleeve <b>40</b><i>a</i>.

The second plurality of detent pockets <b>48</b> can be laterally positioned relative to the first plurality of detent pockets <b>48</b>, for example. In various embodiments, the first and second pluralities of detent pockets <b>48</b> can each be arranged in a row. For example, the sleeve <b>40</b><i>a </i>can have a pair of laterally opposed channels <b>46</b><i>a</i>, <b>46</b><i>b </i>(<figref idref="DRAWINGS">FIG. 5</figref>) on opposing internal side of the sleeve <b>40</b><i>a</i>. The first channel <b>46</b><i>a </i>on the first internal side of the sleeve <b>40</b><i>a </i>can include the first plurality of detent pockets <b>48</b> arranged in a row, for example, and the second channel <b>46</b><i>b </i>on the second internal side of the sleeve <b>40</b><i>a </i>can include the second plurality of detent pockets <b>48</b> arranged in a row, for example. In various embodiments, the first channel <b>46</b><i>a </i>and the first plurality of detent pockets <b>48</b> can form a mirror image reflection of the second channel <b>46</b><i>b </i>and the second plurality of detent pockets <b>48</b>. In other embodiments, the channels <b>46</b><i>a</i>, <b>46</b><i>b </i>and pluralities of detent pockets <b>48</b> on each side of the sleeve <b>40</b><i>a </i>may be asymmetrical.

In various embodiments, each magnetic element <b>122</b><i>a</i>, <b>122</b><i>b </i>can be embedded in a corresponding recess <b>118</b><i>a</i>, <b>118</b><i>b </i>in the attachment portion <b>102</b> of the yoke <b>108</b>. For example, the magnetic element <b>122</b><i>a </i>can be at least slightly recessed in the recess <b>118</b><i>a </i>of the yoke <b>108</b>, such that no portion of the magnetic element <b>122</b><i>a </i>projects beyond the mating surface <b>117</b>. Further, the magnetic element <b>122</b><i>b </i>can be at least slightly recessed in the recess <b>122</b><i>b </i>of the yoke <b>108</b>, such that no portion of the magnetic element <b>122</b><i>a </i>projects beyond the mating surface <b>117</b>, for example. Referring still to <figref idref="DRAWINGS">FIG. 24</figref>, the attachment portion <b>102</b> of the yoke <b>108</b> can include an aperture <b>116</b> that extends through the yoke <b>108</b>. The aperture <b>116</b> can be configured to receive the attachment element <b>74</b> (<figref idref="DRAWINGS">FIG. 23</figref>) of the first extension arm <b>60</b><i>a </i>(<figref idref="DRAWINGS">FIG. 23</figref>) when the first extension arm <b>60</b><i>a </i>is positioned relative to the yoke <b>108</b>, for example.

0077Referring now to <figref idref="DRAWINGS">FIGS. 25 and 26</figref>, the magnetic pivot arrangement <b>70</b> can include a pivot plate <b>110</b>, which can include the protrusion <b>112</b>. In various embodiments, the protrusion <b>112</b> can form a curved profile that can match or substantially match the profile of the groove <b>76</b> (<figref idref="DRAWINGS">FIG. 23</figref>). In other words, the protrusion <b>112</b> can define a contour, which can have a radius of curvature that matches the radius of curvature of the groove <b>76</b> contour. For example, at least a portion of the groove <b>76</b> can have a radius of curvature of approximately 0.15 inches to approximately 0.25 inches, and at least a portion of the protrusion <b>112</b> can have a radius of curvature of approximately 0.2 inches. Furthermore, the protrusion <b>112</b> can have a width that is at least slightly smaller than the width of the groove <b>76</b> such that the protrusion <b>112</b> or at least a portion thereof can fit within the groove <b>76</b>. For example, the width of the groove <b>76</b> can be approximately 0.95 inches to approximately 0.105 inches, and the width of the protrusion <b>112</b> can be approximately 0.09 inches to approximately 0.094 inches. In various embodiments, the difference between the width of the protrusion <b>112</b> and the width of the groove <b>76</b> can approximately 0.001 inches to approximately 0.015 inches. In at least one embodiment, the groove <b>76</b> can guide the protrusion <b>112</b> as the protrusion <b>112</b> moves therein. For example, the protrusion <b>112</b> can slide along at least a length of the groove <b>76</b> when the pivot plate <b>110</b> is positioned relative to the first extension arm <b>60</b><i>a</i>. In various embodiments, the length of the protrusion can be approximately 20% to approximately 30% the length of the groove <b>76</b>, for example. Referring still to the <figref idref="DRAWINGS">FIG. 25</figref>, the pivot plate <b>110</b> can include an aperture <b>114</b> therethrough. In various embodiments, the aperture <b>114</b> can be configured to receive the attachment element <b>74</b> (<figref idref="DRAWINGS">FIG. 23</figref>) of the first extension arm <b>60</b><i>a </i>(<figref idref="DRAWINGS">FIG. 23</figref>) when the pivot plate <b>110</b> is positioned relative to the second extension arm <b>60</b><i>a</i>, for example as illustrated in <figref idref="DRAWINGS">FIG. 27</figref>. As described herein, the attachment element <b>74</b> can pivot in the aperture <b>114</b> of the pivot plate <b>110</b> as the extension arm <b>60</b><i>a </i>pivots relative to the yoke <b>108</b> of the first earphone <b>100</b><i>a. </i>

0078Referring to <figref idref="DRAWINGS">FIGS. 24-26</figref>, the pivot plate <b>110</b> can be secured to the attachment section <b>102</b> of the yoke <b>108</b>. In various embodiments, the yoke <b>108</b> can include a mating surface <b>117</b>, and a rim <b>115</b>, which can extend from the mating surface <b>117</b>. The rim <b>115</b> can surround or partially surround the mating surface <b>117</b> of the attachment section <b>102</b>, for example. In various embodiments, the pivot plate <b>110</b> can be positioned relative to the attachment section <b>102</b> of the yoke <b>108</b>, such that the pivot plate <b>110</b> nests in the attachment section <b>102</b>. For example, the pivot plate <b>110</b> can be positioned flush with the mating surface <b>117</b>, and the rim <b>115</b> can extend at least partially around the perimeter of the pivot plate <b>110</b>, for example. In various embodiments, the rim <b>115</b> can help to retain the pivot plate <b>110</b> relative to the yoke <b>108</b>. For example, the rim <b>115</b> can surround or partially surround the pivot plate <b>110</b> to prevent lateral movement of the pivot plate <b>110</b> relative to the yoke <b>108</b>. In certain embodiments, at least a portion of the pivot plate <b>110</b> can be substantially flush with the rim <b>115</b> of the yoke <b>108</b>, and the protrusion <b>112</b> can extend beyond the rim <b>115</b> of the yoke <b>108</b>, for example. The pivot plate <b>110</b> can be non-pivotally secured to the attachment section <b>102</b> of the yoke <b>108</b> such that the projection <b>112</b> remains fixed relative to the yoke <b>108</b> as the first extension arm <b>60</b><i>a </i>pivots relative to yoke <b>108</b> and the first earpiece <b>100</b><i>a</i>. Referring again to <figref idref="DRAWINGS">FIG. 25</figref>, when the pivot plate <b>110</b> is secured to the yoke <b>108</b>, the pivot plate <b>110</b> can enclose and/or retain the magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>in the recessions <b>118</b><i>a</i>, <b>118</b><i>b </i>of the attachment section <b>102</b>. For example, the pivot plate <b>110</b> can cover the magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>positioned in the yoke <b>108</b>. In various embodiments, the pivot plate <b>110</b> can be positioned between the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b </i>positioned in the extension arm <b>60</b><i>a </i>and the magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>positioned in the yoke <b>108</b>. For example, the pivot plate <b>110</b> can extend between the pairs of magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b. </i>

0079Referring now to <figref idref="DRAWINGS">FIGS. 27-29</figref>, the retaining ring <b>105</b> can secure the yoke <b>108</b> to the extension arm <b>60</b><i>a</i>. In various embodiments, the bearing surface <b>74</b> (<figref idref="DRAWINGS">FIG. 23</figref>) of the extension arm <b>60</b><i>a </i>can be positioned relative to the bearing surface <b>119</b> (<figref idref="DRAWINGS">FIGS. 25 and 26</figref>) of the pivot plate and the yoke <b>108</b>. For example, the bearing surface <b>119</b> of the pivot plate can be adjacent to, flush with and/or abutting the bearing surface <b>74</b> of the extension <b>60</b><i>a</i>. The bearing surfaces <b>74</b>, <b>119</b> can be configured to pivot relative to each other, for example. In at least one embodiment, the attachment element <b>74</b> of the first extension arm <b>60</b><i>a </i>can extend through the aperture <b>114</b> in the pivot plate <b>110</b> and/or through the aperture <b>116</b> in the attachment section <b>102</b> of the yoke <b>108</b>. In various embodiments, the retaining ring <b>105</b> can grip the attachment element <b>74</b> between a distal shoulder of the attachment element <b>74</b> and the yoke <b>108</b>. The retaining ring <b>105</b> can hold the attachment element <b>74</b> within the apertures <b>114</b>, <b>116</b> to secure the first extension arm <b>60</b><i>a </i>relative to the yoke <b>108</b>, for example. In various embodiments, a shouldered portion of the attachment element and/or a washer <b>104</b> can be positioned between the retaining ring <b>105</b> and the yoke <b>108</b>.

0080Referring still to <figref idref="DRAWINGS">FIGS. 27-29</figref>, when the attachment element <b>74</b> engages the yoke <b>108</b> to secure the first extension arm <b>60</b><i>a </i>to the yoke <b>108</b>, the pivot plate <b>110</b> can be positioned and held therebetween. In other words, the pivot plate <b>110</b> can be sandwiched between the first extension arm <b>60</b><i>a </i>and the yoke <b>108</b>, for example. In certain embodiments, the attachment element <b>74</b> and the retaining ring <b>105</b> can secure the pivot plate <b>110</b> between the yoke <b>108</b> and the first extension arm <b>60</b><i>a</i>. Additionally or alternatively, the pivot plate <b>110</b> can be integrally formed with the yoke <b>108</b>. In various embodiments, the pivot plate <b>110</b> can be fixedly secured to the yoke <b>108</b>, and the protrusion <b>112</b> can extend into the groove <b>76</b> in the extension arm <b>60</b><i>a</i>. Further, in at least one embodiment, the attachment element <b>74</b> of the first extension arm <b>60</b><i>a </i>can pivot in the apertures <b>114</b>, <b>116</b> (<figref idref="DRAWINGS">FIGS. 24 and 25</figref>) of the yoke <b>108</b> as the first extension arm <b>60</b><i>a </i>pivots relative to the yoke <b>108</b>. As the attachment element <b>74</b> pivots in the apertures <b>114</b>, <b>116</b>, the protrusion <b>112</b> extending from the pivot plate <b>110</b> can slide in the groove <b>76</b> of the extension arm <b>60</b><i>a. </i>

0081Referring primarily to <figref idref="DRAWINGS">FIG. 29</figref>, the groove <b>74</b> can include rotational stops <b>77</b><i>a</i>, <b>77</b><i>b</i>. In various embodiments, the attachment element <b>74</b> can pivot in a first direction relative to the yoke <b>108</b> until the protrusion <b>112</b> in the groove <b>76</b> abuts the first rotational stop <b>77</b><i>a</i>, and the attachment element <b>74</b> can pivot in a second, opposite direction relative to the yoke <b>108</b> until the protrusion <b>112</b> in the groove <b>76</b> abuts the second rotational stop <b>77</b><i>b</i>. In other words, the rotational stops <b>77</b><i>a</i>, <b>77</b><i>b </i>can limit the range of rotation of the first extension arm <b>60</b><i>a </i>relative to the yoke <b>108</b>. In various embodiments, the rotational stops <b>77</b><i>a</i>, <b>77</b><i>b </i>of the groove <b>76</b> can permit approximately +/−90 degrees or rotation, or 180 degrees of rotation, for example. In other embodiments, the rotational stops <b>77</b><i>a</i>, <b>77</b><i>b </i>of the groove <b>76</b> can permit less than 180 degrees or more than 180 degrees, for example. In at least one embodiment, the groove <b>76</b> can comprise a complete loop or contour such that the groove <b>76</b> does not include rotational stops <b>77</b><i>a</i>, <b>77</b><i>b</i>. In certain embodiments where the groove <b>76</b> forms a complete loop, the extension arm <b>60</b><i>a </i>can rotate +/−360 degrees, for example.

0082In various embodiments, when the first extension arm <b>60</b><i>a </i>pivots relative to the yoke <b>108</b>, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b </i>in the extension arm <b>60</b><i>a </i>can pivot relative to the magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>in the yoke <b>108</b>. The magnetic poles of the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>can be arranged such that the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b </i>in the first extension arm <b>60</b><i>a </i>seek to substantially align with the corresponding magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>in the yoke <b>108</b>. For example, the magnetic element <b>78</b><i>a </i>can seek alignment with the magnetic element <b>122</b><i>a</i>, and the magnetic element <b>78</b><i>b </i>can seek alignment with the magnetic element <b>122</b><i>b</i>. In various embodiments, when the yoke is pivoted away from a neutral position and into a second, pivoted position, as described herein, a magnetic attraction between the magnetic element <b>78</b><i>b</i>, for example, and the magnetic element <b>122</b><i>b</i>, for example, can pull the magnetic poles of the magnetic elements <b>78</b><i>b</i>, <b>122</b><i>b </i>toward alignment. In other words, the magnetic element <b>78</b><i>a </i>can exert a magnetic pulling force on magnetic element <b>122</b><i>a</i>, and magnetic element <b>78</b><i>a </i>can exert a magnetic pulling force on magnetic element <b>122</b><i>b</i>. Further, in various embodiments, the magnetic element <b>78</b><i>a </i>can resist alignment with the magnetic element <b>122</b><i>b</i>, and the magnetic element <b>78</b><i>b </i>can resist alignment with the magnetic element <b>122</b><i>a</i>, for example. For example, when yoke is pivoted away from a neutral position and into a second pivoted position, as described herein, the magnetic element <b>78</b><i>a </i>can exert a magnetic pushing force on magnetic element <b>122</b><i>b</i>, and magnetic element <b>78</b><i>b </i>can exert a magnetic pushing force on magnetic element <b>122</b><i>b</i>. In various embodiments, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>can be made of hard, magnetic material. The magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>can be permanent magnets, for example.

0083In various embodiments, the yoke <b>108</b> can pivot between a neutral position and pivoted positions. For example, the yoke <b>108</b> can pivot between a first neutral position, a counterclockwise second position, and clockwise second position. The first position can be between the counterclockwise second position and the clockwise second position, for example. In various embodiments, the magnetic element <b>78</b><i>a </i>can be aligned with the magnetic element <b>122</b><i>a </i>and the magnetic element <b>78</b><i>b </i>can be aligned with the magnetic element <b>122</b><i>b </i>when the yoke <b>108</b> is in the first, neutral position relative to the extension arm <b>60</b><i>a</i>. When the yoke <b>108</b> pivots toward the counterclockwise or clockwise second position, the magnetic element <b>78</b><i>a </i>can move out of alignment with magnetic element <b>122</b><i>a </i>and the magnetic element <b>78</b><i>b </i>can move out alignment with the magnetic element <b>122</b><i>b</i>. As the yoke <b>108</b> pivots toward the clockwise second position, magnetic element <b>78</b><i>a </i>can move toward alignment with the magnetic element <b>122</b><i>b</i>. In various embodiments, the poles of magnetic elements <b>78</b><i>a</i>, <b>122</b><i>b </i>can be arranged such that the magnetic elements <b>78</b><i>a</i>, <b>122</b><i>b </i>resist alignment. In other words, magnetic element <b>78</b><i>a </i>can exert a magnetic pushing force on magnetic element <b>122</b><i>b</i>, for example. As the yoke <b>108</b> pivots toward the counterclockwise second position, the magnetic element <b>78</b><i>b </i>can move toward alignment with the magnetic element <b>122</b><i>a</i>. In various embodiments, the poles of magnetic elements <b>78</b><i>b</i>, <b>122</b><i>a </i>can be arranged such that the magnetic elements <b>78</b><i>b</i>, <b>122</b><i>a </i>resist alignment. In other words, the magnetic element <b>78</b><i>b </i>can exert a magnetic pushing force on magnetic element <b>122</b><i>a</i>, for example. In at least one embodiment, when the yoke <b>108</b> is in the first position relative to the arm <b>60</b><i>a</i>, the positive pole of the magnetic element <b>78</b><i>a </i>can correspond to the negative pole of the magnetic element <b>122</b><i>a</i>, for example, and the negative pole of the magnetic element <b>78</b><i>b </i>can correspond to the positive pole of the magnetic element <b>122</b><i>b</i>, for example. The reader will understand that the magnetic pivot arrangement <b>70</b> can include additional or fewer magnetic elements, that alternative arrangements of the magnetic elements are possible, and that such arrangements are within the scope of this disclosure.

0084In use, a user can adjust or manipulate the assembly <b>20</b> by pivoting the yoke <b>108</b> relative to the attached extension arm <b>60</b><i>a</i>. For example, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b </i>in the first extension arm <b>60</b><i>a </i>can be pivoted out of alignment with the magnetic elements <b>122</b><i>a</i>, <b>122</b><i>b </i>of the yoke <b>108</b> when the user positions the assembly <b>20</b> relative to the user's head and/or neck. Once misaligned, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>of the magnetic pivot arrangement <b>70</b> can seek to realign. In various embodiments, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b </i>can exert a magnetic pull on magnetic elements <b>122</b><i>a</i>, <b>122</b><i>c </i>to pivot or attempt to pivot the magnetic pivot arrangement <b>70</b> back into realignment. In certain embodiments, the magnetic pull or force generated by the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>can hold the assembly <b>20</b> in position relative to a user's head or neck. For example, the magnetic elements <b>78</b><i>a</i>, <b>78</b><i>b</i>, <b>122</b><i>a</i>, <b>122</b><i>b </i>can exert a force that comfortably secures the earphone assembly without apply an excessive force to the user's head and/or neck. Further, when the assembly <b>20</b> is removed from the user's head or neck and/or when the user stops actively adjusting the assembly <b>20</b>, the magnetic pivot mechanism <b>70</b> can pivot the yoke <b>108</b> relative to the first extension arm <b>60</b><i>a </i>such that the magnetic pivot arrangement <b>70</b> returns to alignment and the assembly <b>20</b> returns to its initial configuration. In other words, the yoke can pivot back to the neutral position.

0085Referring primarily to <figref idref="DRAWINGS">FIGS. 30-34</figref>, the first earphone <b>100</b><i>a </i>can include the housing pivot arrangement <b>130</b>, which can permit the housing ring <b>152</b> to pivot relative to the yoke <b>108</b>. For example, the housing ring <b>152</b> can be pivotally secured to the yoke <b>108</b> at a housing pivot arrangement <b>130</b>. In certain embodiments, the housing ring <b>152</b> can be pivotally secured to the yoke <b>108</b> at two opposing housing pivot arrangements <b>130</b>. As described herein, the housing ring <b>152</b> can be secured to the yoke <b>108</b> by the housing pivot arrangement <b>130</b>, which can permit the housing ring <b>152</b> to pivot relative to the yoke <b>108</b>, for example.

The reader will understand that various different and/or additional components can help to retain the collar <b>132</b> relative to the housing ring <b>152</b>.

0088Referring primarily to <figref idref="DRAWINGS">FIG. 35</figref>, the pivot pin <b>138</b> of the housing pivot arrangement <b>130</b> can engage the yoke <b>108</b>. In various embodiments, the yoke can have a hub <b>144</b>, and a portion of the pivot pin <b>138</b> can extend into an aperture <b>143</b> (<figref idref="DRAWINGS">FIG. 24</figref>) in the hub <b>144</b>. In various embodiments, the yoke <b>108</b> can have two hubs <b>144</b> on opposing sides of the yoke <b>108</b>, for example, and a pivot pin <b>138</b> can be secured to each hub <b>144</b>. The pivot pin <b>138</b> can be fastened or secured to the hub <b>144</b>, for example, or can be integrally formed with the hub <b>144</b>, for example. In various embodiments, the pivot pin <b>138</b> can be fixedly or non-pivotally connected to the hub <b>144</b> of the yoke <b>108</b>. Referring again to <figref idref="DRAWINGS">FIGS. 30-34</figref>, the yoke <b>108</b> can extend at least partially around the housing ring <b>152</b>, such that the hubs <b>144</b> of the yoke <b>108</b> are positioned on opposite sides of the housing ring <b>152</b>, for example. Further, the pivot pins <b>138</b>, which extend from the hubs <b>144</b>, can each extend through an aperture <b>145</b> (<figref idref="DRAWINGS">FIG. 31</figref>) in the housing ring <b>152</b> and into the collar <b>132</b> that is secured therein. In various embodiments, the housing ring <b>152</b> can be pivotally connected to the yoke <b>108</b> by the housing pivot arrangement <b>130</b>, which includes the collar <b>132</b> and the pivot pin <b>138</b>. For example, the pivot pin <b>138</b> extending from the housing ring <b>152</b> can pivot within the aperture <b>145</b> of the housing ring <b>152</b> and in the collar <b>132</b>. In certain embodiments, the housing ring <b>152</b> can be pivotally connected to the yoke <b>108</b> at opposing housing pivot arrangement <b>130</b> positioned on opposite sides of the housing ring <b>152</b>. In other words, the housing ring <b>152</b> can pivot relative to the yoke <b>108</b> at opposing housing pivot arrangements <b>130</b>. The collar <b>132</b> can be fixed relative to the housing ring <b>152</b>, such that pivoting of the pivot pin <b>138</b> causes the yoke <b>108</b> to pivot in the collar <b>132</b> and relative to the housing ring <b>152</b>. As described herein, the collar <b>132</b> can control the rotational direction and/or the range of rotation of the pivot pin <b>138</b> and the yoke <b>108</b> relative to the housing ring <b>152</b>, for example.

0089In various embodiments, referring primarily to <figref idref="DRAWINGS">FIG. 36-38</figref>, the collar <b>132</b> can include an opening or space <b>135</b>, an arm <b>134</b>, and/or a wedge stop <b>136</b>. The arm <b>134</b> can define a first side or surface of the opening <b>135</b>, for example, and/or the wedge stop <b>136</b> can define a second side or surface of the opening <b>135</b>, for example. In various embodiments, the wedge stop <b>136</b> surface can be angularly oriented relative to the arm <b>134</b> surface, for example. In certain embodiments, as described herein, the pivot pin <b>138</b> can be received in the opening <b>135</b> of the collar <b>136</b>. For example, the pivot pin <b>138</b> can extend from the hub <b>144</b> of the yoke <b>108</b> (<figref idref="DRAWINGS">FIG. 35</figref>) and to between the arm <b>134</b> and the wedge stop <b>136</b> of the collar <b>132</b>. The arm <b>134</b> and the wedge stop <b>136</b> can control the pivoting movement of the pivot pin <b>138</b> in the opening <b>135</b>. For example, the pivot pin <b>138</b> can pivot counterclockwise from the vertical configuration (<figref idref="DRAWINGS">FIG. 37</figref>) until the pivot pin <b>138</b> reaches the wedge stop <b>136</b>. In various embodiments, as the pivot pin <b>138</b> pivots towards the wedge stop <b>136</b>, the arm <b>134</b> can flex, move outward or deform to accommodate the pivot pin <b>138</b>. Further, when the pivot pin <b>138</b> abuts the wedge stop <b>136</b> further rotation of the pivot pin <b>138</b> can be prevented by the wedge stop <b>136</b>. Referring still to <figref idref="DRAWINGS">FIGS. 37-39</figref>, clockwise rotation of the pivot pin from the vertical configuration (<figref idref="DRAWINGS">FIG. 38</figref>) can be prevented by the flexible arm <b>134</b> and the non-wedged portion of the collar <b>132</b>. In alternative embodiments, the opening <b>135</b> in the collar <b>132</b> can permit approximately 20 degrees of rotation, for example. In other embodiments, the opening <b>135</b> can permit less than or more than 20 degrees of rotation, for example. Further, in various embodiments, the opening <b>135</b> can be configured to permit clockwise rotation and prevent counterclockwise rotation, for example.

0090In various embodiments, the collar <b>132</b> can be more flexible than the pivot pin <b>138</b> such that the arm <b>134</b> of the collar <b>132</b> substantially flexes or deforms and the pivot pin <b>138</b> substantially maintains its shape when the pivot pin <b>138</b> pivots into and/or against the arm <b>134</b>. For example, the collar <b>132</b> can comprise a sufficiently resilient material, such that the flexible <b>134</b> can flex or deform to accommodate the pivot pin <b>138</b>, and can subsequently return or substantially return to its undeformed position when the pivot pin returns to its initial, non-pivoted configuration. In certain embodiments, the collar <b>132</b> can comprise an elastomeric material such as urethane, for example. Further, in certain embodiments, the pivot pin <b>138</b> can comprise a substantially rigid material such as brass, for example.

0091Referring again to <figref idref="DRAWINGS">FIGS. 32 and 33</figref>, in use, the pivot pin <b>138</b> can pivot or turn in the collar <b>130</b> to adjust the position of the yoke <b>108</b> relative to the housing ring <b>152</b>. For example, the pivot pin <b>138</b> can pivot away from the arm <b>134</b> toward the wedge stop <b>136</b> when the user positions the assembly <b>20</b> relative to the user's head and/or neck. When the pivot pin <b>138</b> pivots toward the wedge stop <b>136</b>, the pivot pin <b>138</b> can exert a force on the arm <b>134</b> such that the arm <b>134</b> deforms or flexes to accommodate the pivot pin <b>138</b>. In various embodiments, the arm <b>134</b> can exert a springback force on the pivot pin <b>138</b>, which can help to maintain the relative positions of the yoke <b>108</b> and the housing ring <b>152</b>, for example. Furthermore, the relative positions of the yoke <b>108</b> and the housing ring <b>152</b> can help to hold the assembly <b>20</b> in position relative to a user's head or neck. For example, the ring housing <b>152</b> can be pivoted toward a user's ear, such that the ear cushion <b>148</b> of the earpiece <b>100</b><i>a </i>exerts a force on the user's ear that comfortably secures the assembly <b>20</b> relative to the user's head and/or neck without applying an excessive force thereto. Further, when the assembly <b>20</b> is removed from the user's head or neck and/or when the user stops actively adjusting the assembly <b>20</b>, the arm <b>134</b> of the collar <b>132</b> can exert a force on the pivot pin <b>138</b> that causes the pivot pin <b>138</b> to pivot away from the wedge stop <b>136</b> and toward the arm <b>134</b> such that the housing pivot mechanism <b>130</b> pivots the ring housing <b>152</b> relative to the yoke <b>108</b> and the assembly <b>20</b> returns to its initial configuration.
