Gooseneck microphone with holder in form of spherical head

State of the art

The invention is based on a so-called gooseneck microphone according to the preamble the independent claim from.

So-called gooseneck microphones are distinguished in that the actual Microphone is attached to a plastically deformable rod-shaped retaining element which in turn is rigidly attached to a console. The deformability of the Holding member serves the microphone by bending of the holding element in a desired position, preferably near the mouth of the user to pivot. The Retaining element thereby has a sufficient stability, the microphone after his keep swinging in the pivoted position. Such gooseneck microphones for example, for hands-free mobile handset in Motor vehicles or used for an announcement in travel or city buses.

ADVANTAGES OF THE INVENTION

The gooseneck microphone invention having the characteristics of independent Patent claim has the advantage of additional degrees of freedom, and in particular a larger Pivoting range when adjusting the microphone position.

Advantageous embodiments of the invention are in the dependent claims are given and below in connection with the embodiments the invention described in greater detail.

Description of Embodiments

Figure 1 shows the rear view of the vehicle seat Rückeulehneines 1, here for example, the driver's seat in a motor vehicle. Against the backrest of the vehicle seat 1 is a Gooseneck microphone 2 is fastened by means of a ball head bearing 21st The Gooseneck Microphone 2 includes firstly the actual microphone capsule 23, to other a plastically deformable hollow rod-shaped retaining element 22, on which the Microphone 23 is fixed. The holding member 22 itself, and thus the Gooseneck Microphone 2 in turn by the ball head bearing 21 at the Backrest 1 attached.

The ball head bearing 21 causes the entire gooseneck microphone 2 in a partially, almost hemispherical space vertically upwards or sideways is pivotable. In combination with the rudimentary any deformability of Gooseneck 22 or retaining element 22 are obtained for the position of actual Microphone capsule 23 is a plurality of possible positions. In particular, the Microphone 2 in the drawing indicated by means of ball head bearing 21 and Deformability of the retaining element 22 can be adjusted so that it at the mouth of a is to keep on the vehicle seat seated person.

The ball head bearing 21 is designed so that the frictional torque generated by them sufficient to provide an adjustment of the microphone position by vibrations, as the Drive over uneven floors or running troubles of a vehicle internal combustion engine etc. arise, surely prevent. The friction torque of The ball joint 21 is the other hand, also be set so low that the microphone 23 can be manually pivoted about the ball joint 21st

According to a further advantageous Ausfihrungsform, the friction torque of be set ball joint 21 so that a pivoting of the Gooseneck microphone in a horizontal plane relatively easily, in a vertical plane is however made possible with a comparatively high torque. the is based on the consideration that shocks the microphone 2 as a result of Gravity is principally engaged in vertical forces on the assembly, accordingly, the Friction torque for pivoting the microphone 2 in the vertical direction must be high, however, horizontal forces are comparatively low and thus a is less friction in the horizontal direction necessary to the microphone 2 in the current position to hold. This is based on the further consideration that For example, in the case of collision of the vehicle with an obstacle, the microphone 2 a user thus thrown in the direction of travel head a possible should oppose little resistance, to avoid injury.

Achieving a suitable friction torque to meet the above-mentioned Boundary conditions is performed advantageously in the attempt.

Figure 2 shows an advantageous embodiment of the ball joint 21. This includes first as a central component of a ball 211 at the fixed gooseneck 22 is. In the present case the gooseneck 22 in a cylindrical blind bore 215 the ball was added 211 and bonded, for example in or by means of on the Outside of the gooseneck 22 mounted in this area thread screwed. The ball 211 is held in a bearing ring 212 that on a is attached flange plate 11 on the side of the vehicle seat. The flange plate can eg be welded to the tubular frame of the seat. The bearing ring 212 may be made preferably a wear-resistant material, in particular, for example, metal or a made wear-resistant plastic and on the backrest of the vehicle seat 1 be used. Bearing ring 212 and ball 211 together form the ball joint 21 and Ball joint bearing 21 diameter bearing ring 212 and ball 211 are such each adapted to a desired friction torque for rotating the ball 211 is achieved. Particularly preferably, the bearing ring may be slightly out of round be designed such that a pivoting of the ball in a vertical plane, in the drawing in the sheet plane, a higher friction torque precludes than Pivoting in a horizontal, in the drawing perpendicular to the plane stationary plane.

The runout of the bearing ring, for example, by drawing in the not Turnbuckles shown are achieved, the bearing ring in itself or against the Flange plate clamp 11 of the backrest. Alternatively or additionally, further rounder his terminal screws provided the approximately 211 similar to a the ball head Tripod braced against the bearing ring 212 and the friction torque in affect the desired manner.

The ball 211 has another with the blind bore 215 aligned, with respect to the Blind bore thinner to bore 213, through the through the interior 214 of the Gooseneck 22 guided cable 24 of the microphone 23 are converted into the seat inside. From there, the cable 24 are guided to a further signal processing not shown.

The degrees of freedom by which the ball 211 can be pivoted, are protected by the Holding member 22 is limited, for the stops are formed in the bearing ring.
