Definitions

  • the present invention relates to an in-the-ear hearing device with a housing section designed for insertion into the auditory canal and containing at least the earphone and an adjoining outer housing section, in which device components, such as a microphone, potentiometer, and at least part of the electronics, in the form of a plug-in module and the battery are housed and which is covered by a front panel with an opening for inserting the module.
  • device components such as a microphone, potentiometer, and at least part of the electronics, in the form of a plug-in module and the battery are housed and which is covered by a front panel with an opening for inserting the module.
  • the so-called in-the-ear hearing aids occupy a special position in that they are worn extremely discreetly, partly in the external auditory canal and partly in the auricle.
  • the behind-the-ear hearing aids and the hearing glasses are the most widespread today. Thanks to today's miniaturization technology, the most essential parts of the hearing aid, namely the microphone, the electronics (amplifier stages, control elements), the battery and the earphone or loudspeaker, can be put into the associated joint behind the ear or the pinna to some extent without problems Housing.
  • the in-the-ear hearing aids under discussion thus have a housing or casing section which can preferably be adapted to the individual space available in the external auditory canal of the future user and which at least accommodates the receiver or loudspeaker and possibly some of the electronics, and an adjoining section, which comes to lie in the auricle in front of the ear canal, which contains the microphone, the battery and the electronics or at least a part thereof.
  • the on / off switch and the rotary knob for the volume control (potentiometer) should also be arranged in this outer section of the device.
  • the receiver or loudspeaker is built into the device section to be adapted to the hearing channel from the start.
  • the rest of the device i.e. the microphone, the electronics etc., which are advantageously in the form of a finished module, are inserted into the outer section of the device.
  • the connection conductors of the receiver are to be connected to the associated inputs of the module mentioned, i.e. to be soldered in practice, because plug connections are practically out of the question due to the individual final designs.
  • the purpose of the present invention is now to create a new type of construction which allows simple, secure connection of the components located in the auditory canal section of the device to the other electronic or electrical components of the device.
  • This task is for an in-the-ear hearing device with a housing section designed for insertion into the auditory canal and containing at least the listener and an adjoining outer housing section, in which device components, such as a microphone, potentiometer, and at least part of the electronics in the form of a plug-in module and the battery are housed and which is covered by a front panel with an opening for inserting the module, according to the invention solved in that electrical contacts are installed at the edge or near the edge of the front panel opening, to which the built-in device components are connected and which at the module used interact with corresponding counter contacts arranged on it.
  • the mating contacts are preferably arranged on the outer wall of the part of the plug-in module protruding into the housing interior, for example in the form of contact plates or at least partially contact strips running around the outer wall.
  • the built-in electronic contacts can be resilient tongues which interact with counter-contact strips arranged on the bottom of circumferential grooves and at the same time fix the plug-in module in such a way that it can still be rotated, for example in order to adjust the potentiometer housed inside the housing with such a rotary movement.
  • Fig. 1 of the drawing illustrates in the form of a block diagram the general structure of a hearing aid.
  • the individual components namely the microphone 1, the amplifier or the electronics 2, the battery 3, the volume control or the potentiometer 4 and the receiver or loudspeaker 5, which are packaged together in a suitable housing, are the hearing aid , in particular an in-the-ear hearing aid 6, more or less miniaturized.
  • FIG. 2 shows, purely schematically, an in-the-ear hearing aid 6 which is inserted into an ear and which comprises a housing section 6a lying in the pinna and a housing section 6b adjoining it and individually adapted to the auditory canal.
  • the shape-adaptable section 6b can be angled, curved or even more or less straight.
  • the mentioned device components such as amplifier 2, battery 3, potentiometer 4 with rotary knob 4a, handset 5, etc. are housed.
  • FIG. 3 shows, on an enlarged scale, a schematic section through an in-the-ear hearing device known per se.
  • the receiver 5 is accommodated in the housing section 6b, be it before or after the individual adaptation of the device to the auditory canal in which the device is to be inserted.
  • the other components are subsequently used together with a front plate 7 or through an opening 7a in the latter, the main difficulty in connecting being the soldering of the connecting conductors coming from the receiver 5, for example L 1 , L 2 and L 39, to the corresponding inputs of the electronics 2 . So far, this has been done with specially trained personnel, taking a lot of time and risk of errors.
  • the front plate 7 has an opening 8 through which the electronics 2, possibly together with the microphone and potentiometer, is inserted into the housing 6 as the finished module 9.
  • the connecting conductors L 1 , L 2 , L 3 coming from the receiver 5 were already connected, for example soldered, to electrical contacts K 1 , K 2 and K 3 before the module 9 was inserted, which contacts were arranged on or near the edge of the front panel opening 8 were permanently installed.
  • Corresponding mating contacts K 1 ', K 2 ' and K 3 ' are arranged on the plug-in module 9, more precisely on its outer wall, and in turn are electrically connected to the associated components.
  • soldering or connection of the connecting conductors L 1 , L 2 , L 3 to the contacts K 1 , K 29 K 3 can be carried out easily and absolutely securely because of the optimal accessibility before the module 9 is inserted.
  • FIG 5 shows a further embodiment of a hearing device 6 designed according to the invention (with the plug-in module omitted).
  • the contacts K 1 , K 2 and K 3 are arranged in the form of resilient tongues 10, 11 and 12 on the edge of the opening 8 of the front plate 7.
  • knobs 10', 11 ', 12' provided on the spring tongues 10, 11, 12 can with the module 9 inserted, snap into the recesses, make the desired electrical connections there and at the same time hold the plug-in module 9.
  • the above-mentioned recesses are formed as grooves running partially around the module, the module 9, which is fixed with respect to the insertion direction, can also be rotated about its axis and serve, for example, as an adjustment button for a potentiometer which is fixedly mounted with respect to the housing (see Swiss patent no. With the same registration date) ).
  • FIG. 6 of the drawing is a representation of a further embodiment similar to FIG. 5.
  • the contacts K 1 , K 2 (for example only two contact points are provided here) are arranged on a type of cage 13 which is mounted in section 6a of the hearing device housing.
  • the cage 13 can serve, for example, as a support for the potentiometer 4 and thus enable its adjustment by means of the rotatable plug-in module 9.
  • the plug-in module can contain, for example, the microphone, the amplifier or the electronics and the required battery.
