Such a hearing aid microphone and are, for example, in the <patcit><text>WO-A-95/22879</text></patcit> disclosed.
Although hearing aids today are much smaller than a few years ago, while their reliability and sound quality have been improved, still remain drawbacks to be overcome. These are, for example, to the number of wires necessary to connect the microphone, amplifier, receiver and battery. These wires can the reliability of the hearing impair and expensive its production. Furthermore, they are at least partially the cause of interference from cell phones and other RF sources. There are therefore expensive solutions are needed to prevent such interference. Another drawback is the size of the known hearing aids that are still too large to fit as a (mini) canal instrument (CIC hearing aid) for all ears.
In the known hearing aids, the microphone is generally an electret microphone with integrated CMOS or JFET buffer stage. The amplifier comprises one or more discrete components and integrated circuits on a hybrid circuit board. The recipient is generally a design with balanced armature ( "balanced armature").
In the hearing aid <patcit><text>WO-A-95/22879</text></patcit> has the microphone case, conventional ports for connecting a battery via wires.
The <patcit><text>EP-A-0802700</text></patcit> describes a microphone, the housing includes a differential preamplifier.
The <patcit><text>DE-A-19545760</text></patcit> proposes to incorporate a microphone in a hearing aid for an A / D converter, while according to the <patcit><text>US-A-4,592,087</text></patcit> and the <patcit><text>US-A-4,689,819</text></patcit> the power amplifier is to be integrated into the microphone of a hearing aid.
The invention seeks to overcome the remaining drawbacks of the known hearing aid at least partially, and this provides a hearing aid of the type stated, which is characterized in that the connecting devices are designed to connect the microphone to the battery as a solid, spring-loaded connections that a solderless contact produced between the amplifier device and the battery terminals.
Furthermore, the hearing aid according to the second embodiment is characterized in that the input devices which can enter the sound waves into the microphone housing, are provided in the battery holder, and that the input means are formed by openings in a removable cover on the bottom of the battery holder and of facing the bottom wall surface of the microphone housing are formed.
The microphone according to the invention is characterized in that the connecting means are designed for connecting the microphone to the battery as a fixed spring biased connections which create a solderless contact between the amplifier means and the battery terminals.
<?page 3?>It is noted that the <patcit><text>EP-A-0332938</text></patcit> shows a hearing aid, in which the electronic circuitry of the hearing device comprises contact springs which provide a solderless contact with the battery terminals at one end.
Embodiments of the invention and its advantages are discussed below with reference to the figures of the drawing.
<figref idrefs="S10">1</figref> is a section through a first embodiment of the invention;
<figref idrefs="S11">2</figref> is a section through a second embodiment of the invention; and
<figref idrefs="S12">3</figref> is a section through a third embodiment of the invention.
The <figref idrefs="S10">1</figref> shows a part of a main part <figref>1</figref> a hearing device with a battery holder <figref>2</figref> with removable cap <figref>2a</figref> for a battery <figref>3</figref>, A receiving space for the housing of a microphone <figref>4</figref> and an inlet channel <figref>5</figref>By sound waves from the exterior ago the inlet opening <figref>6</figref> may run into a wall of the microphone housing.
The microphone is a conventional microphone of the Elektroet type, as for example, in the <patcit><text>US-A-5,255,246</text></patcit> is described; Details of the microphone are not executed here because they are not actually relevant to the present invention. A hybrid circuit<figref>7</figref> is provided on which an integrated circuit (IC) <figref>8th</figref> and possibly passive components <figref>9</figref>. <figref>10</figref> are arranged by means of a flip-chip technology or wire bonding. The connection of the microphone to the substrate of the hybrid circuit is provided by a flexible compound of the<patcit><text>US-A-5,255,246</text></patcit> type disclosed. At the present on the housing exterior side of the hybrid substrate, are soldering surfaces <figref>12</figref>. <figref>12a</figref> to connect the microphone to the battery terminals via lines <figref>13</figref>. <figref>14</figref> and intended to extract the output of an amplifier in the receiver IC. For clarity, only the solder surfaces<figref>12</figref>. <figref>12a</figref> shown but not provided for connecting the receiver and the receiver itself; whose structure is to those skilled in the art.
a film strip with printed lines ( "flex print"), for example - - Instead of soldering surfaces also lends itself to connecting devices. use, instead of a hybrid circuit and a printed circuit board or flex print.
by In the structure of a microphone <figref idrefs="S10">1</figref> are all sensitive electronic parts from the outside world by the metal housing of the microphone and by the side of the hybrid circuit shielded, on the ground plane is. External components such as. The components<figref>9</figref>. <figref>10</figref>Which for example for decoupling the power supply are needed., Need not be screened because they either work at a relatively high signal level and therefore to RF interference are not much less or sensitive.
In the embodiment of <figref idrefs="S10">1</figref> the microphone can have a round, rectangular or other desired shape.
The <figref idrefs="S11">2</figref> shows another embodiment of the invention, in which the number of connecting wires is further reduced. The same components as those of the<figref idrefs="S10">1</figref> are provided with the respective same, but increased by 100. Numeral. The hybrid circuit is now arranged in the main body so that it lies facing a side of the battery. Spring preloaded fasteners<figref>114</figref>. <figref>115</figref> are provided to the a battery terminal - to be connected to the hybrid circuit - generally the negative - with the microphone housing and the other battery terminal - in general the positive pole. The connecting wires<figref>116</figref>. <figref>117</figref> to transmit the amplifier output signal to the receiver remain the same, but now come from the other side of the case as in <figref idrefs="S10">1</figref>, These wires are connected by means of the soldering surfaces<figref>112</figref>. <figref>112a</figref> with the hybrid circuit <figref>107</figref> connected. In this embodiment, the microphone is preferably round. Due to the spring-loaded fasteners this hearing aid is under construction very simple and inexpensive, while the short connections to the battery reduces the risk of RF interference radiation.
In the embodiment of <figref idrefs="S12">3</figref> are the connections to the battery and to the receiver are the same as in <figref idrefs="S10">1</figref>; for they are the same, but increased to 200 reference numerals as in<figref idrefs="S10">1</figref> used. In this embodiment, the main part provided in the sound inlet opening for the microphone. changed to an advantageous arrangement. In this embodiment, the sound into the microphone through openings<figref>215</figref> in the wall of the battery holder <figref>202</figref> - Preferably in its cover <figref>202a</figref> - And through an opening <figref>216</figref> in the microphone housing facing wall of the battery holder to enter. In this way, sound waves entering into the battery compartment on the battery holder and the sound inlet of the microphone, etc. well protected from sweat, dust, which often affect the reliability in conventional embodiments. With this configuration also increases the bandwidth of the microphone, as the acoustic mass of the conventional plastic tube as a sound inlet - see Fig.<figref idrefs="S10">1</figref> and <figref idrefs="S11">2</figref>- The frequency response of the microphone adversely affected.
The microphone according to the third embodiment described above requires less volume in a hearing aid than the conventional microphones. Therefore, to reach a greater flexibility in the design of the hearing aid, because, inter alia, the sound inlet no additional space on the front panel of the hearing aid requires is already occupied by switches, potentiometers, etc.. Furthermore, the various manufacturers of hearing aids today require microphones with different sound inlet channels. With the microphone of the third embodiment also, this is now a problem of the past.
