Definitions

  • the invention is based on a so-called gooseneck microphone according to the preamble of the independent claim.
  • So-called gooseneck microphones are characterized by the fact 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 to the microphone by bending the retaining element in a desired position, preferably near the mouth of the user to pivot.
  • the Retaining element has sufficient stability, the microphone after its To keep pivoting in the pivoted position.
  • Such gooseneck microphones For example, for handsfree for mobile phones in Motor vehicles or used for the announcement mode in travel or city buses.
  • the gooseneck microphone according to the invention with the features of the independent Claim has the advantage of further degrees of freedom and in particular a larger Pivoting range when adjusting the microphone position.
  • Figure 1 shows the rear view of remindeulehneines vehicle seat 1, here for example the driver's seat in a motor vehicle.
  • a Gooseneck microphone 2 is attached by means of a ball head bearing 21.
  • the Gooseneck microphone 2 comprises on the one hand the actual microphone capsule 23, for another a plastically deformable hollow rod-shaped holding element 22, on which the Microphone 23 is attached.
  • the holding element 22 itself and thus the Gooseneck microphone 2 is in turn by means of ball bearing 21 at the Backrest 1 attached.
  • the ball bearing 21 causes the entire gooseneck microphone 2 in a partially, almost hemispherical space vertically upwards, or to the side is pivotable.
  • the almost arbitrary deformability of the Gooseneck 22 and holding element 22 result for the position of the actual Microphone capsule 23 a variety of possible positions.
  • that can Microphone 2 as indicated in the drawing by means of ball bearing 21 and Deformability of the retaining element 22 can be adjusted so that it is in front of the mouth of a comes to hold on the vehicle seat person.
  • the ball-bearing 21 is formed so that the friction torque generated by it sufficient to adjust the microphone position due to vibration, as in the case of Driving on uneven floors or by running riot of a vehicle internal combustion engine etc. emerge, sure to prevent.
  • the friction torque of the On the other hand, however, ball joint 21 is also set so low that the microphone 23 can be manually pivoted about the ball joint 21.
  • the friction torque of the Ball joint 21 can be adjusted so that a pivoting of the Gooseneck microphone in a horizontal plane comparatively light, in one vertical level, however, is made possible with a comparatively higher moment.
  • the is based on the consideration that vibrations of the microphone 2 due to the Gravity mainly exercise vertical forces on the arrangement, therefore, the Frictional torque must be high for pivoting the microphone 2 in the vertical direction, on the other hand, horizontal forces are comparatively low and consequently a lower friction torque in the horizontal direction is required to the microphone 2 in to hold the current position.
  • This is further based on the consideration that For example, in the case of the impact of the vehicle on an obstacle, the microphone. 2 a thereby thrown in the direction of travel head of the user as possible low resistance to avoid injury.
  • Figure 2 shows an advantageous embodiment of the ball joint 21.
  • This includes first as a central part of a ball 211, attached to the gooseneck 22 is.
  • the gooseneck 22 is in a cylindrical blind bore 215th taken up the ball 211 and glued, for example, or by means of a on the Outside of the gooseneck 22 threaded in this area screwed.
  • the ball 211 is held in a bearing ring 212 which is connected to a Flange plate 11 is attached to the side of the vehicle seat.
  • the flange plate may e.g. be welded to the tubular frame of the seat.
  • the bearing ring 212 may preferably be made a wear-resistant material, in particular, for example, metal or a made of wear-resistant plastic and on the backrest 1 of the vehicle seat be used. Bearing ring 212 and ball 211 together form the ball joint 21 and Ball Head Bearing 21. Diameter of bearing ring 212 and ball head 211 are such adapted to each other, that a desired friction torque for rotation of the ball 211st is reached.
  • the bearing ring may preferably be slightly out of round be formed, so that a pivoting of the ball in a vertical plane, in the drawing in the leaf level, a higher friction torque opposes, than at Swiveling in a horizontal, in the drawing perpendicular to the sheet standing level.
  • the ball 211 has a further aligned with the blind bore 215, opposite to the Sack bore thinner hole 213 through which passes through the interior 214 of the Gooseneck 22 guided cable 24 of the microphone 23 are guided into the interior of the seat. From There, the cables 24 are further guided to a signal processing, not shown.
  • the degrees of freedom by which the ball 211 can be pivoted are by the Retaining element 22 limited, are formed for the stops in the bearing ring.
  • the mentioned Stops or the Verschwenkungsbegrenzung for the gooseneck 22 causes zuatzlich advantageously a shearing protection for the cable 24 of the microphone 23rd
