Definitions

  • the present invention relates to a mounting housing for receiving a cylindrical electro-acoustic transducer having on its back non-rotationally symmetrical contacting surfaces for automatic contacting, connection pins and at least one non-rotationally symmetrically arranged sound inlet opening.
  • the object of the present invention is therefore to provide a mounting housing for electro-acoustic transducers of the type mentioned above, with a simple way reliable automatic contact is made possible.
  • a mounting housing comprises a receiving plate for the transducer with two receiving bores for guiding the connecting pins, at least one radially oriented groove, which is located below a sound inlet opening, and by two Receiving holes, which are located below the contacting surfaces for automatic contacting, in which coil springs are held, which protrude on the side opposite to the side adjacent to the acoustic transducer, and a pluggable over the acoustic transducer cap whose edge with the edge of Receiving plate can be latched, and which has at least one sound inlet bore, which adjoins a sound inlet groove of the receiving plate.
  • the mounting housing according to the present invention provides a stable, vibration-proof contacting principle with a uniform contact force over large height tolerances. Another advantage is that there is little risk of plastic deformation. For microphones with rearward sound inlet opening there is the possibility of hand soldering-free automatic contacting with a defined acoustic behavior in that the existing connection pins are used to uniquely define the position of the electroacoustic transducer.
  • An expedient development of the present invention is characterized in that the end of the spiral spring, which is in contact with the transducer, has a larger diameter than the remaining part of the spiral spring, and that the inner dimensions of the receiving bores for the coil springs are adapted to the outer dimensions of the coil springs ,
  • the in the FIGS. 1 to 3 shown electroacoustic transducer in the present case a microphone capsule, has front rotationally symmetrical sound inlet openings 5 and a rear non-rotationally symmetrical sound inlet opening 6. Furthermore, the microphone capsule shown has on the back pins 4 and solder pads 3 for other types of connections such as leaf springs.
  • This receiving plate 7 has corresponding holes 13 for receiving the pins 4. This causes a fixed orientation of the microphone capsule to the receiving plate 7 causes. At defined intervals to these pins 4 contacting surfaces are then realized on the rear wall of the microphone capsule.
  • the sound inlet groove 9 in the receiving plate comes to lie exactly below the rear sound inlet opening 6.
  • a cap 8 Via the receiving plate 7 with the microphone capsule 1, a cap 8, which e.g. made of rubber, to be inverted to achieve a seal against unwanted sound entrances.
  • the cap 8 has a sound inlet bore 10, which is arranged such that it adjoins the sound inlet groove 9 in the receiving plate 7, so that a continuous rear sound inlet opening is ensured.
  • spiral springs 11 At one end with a larger diameter. Then, for contacting with the solder pads 3 of the microphone capsule 1, the larger-diameter ends are used, and the smaller-diameter ends are used for contacting to the outside.
  • the larger-diameter ends are used, and the smaller-diameter ends are used for contacting to the outside.
  • bore is adapted to these diameters, so that in this case results in a self-retaining spring contact during assembly.
