Definitions

  • the invention relates to a specified in claim 1 electroacoustic miniature transducer, a specified in claim 9 holding frame and specified in the claims 10 and 11 hearing aids.
  • Electroacoustic miniature transducers are used to convert acoustic to electrical signals and to convert electrical to acoustic signals.
  • an acoustic signal is picked up by an electroacoustic miniature transducer (microphone) and further processed, and an acoustic signal is emitted from an electroacoustic miniature transducer (earpiece, loudspeaker).
  • an electroacoustic miniature transducer microphone
  • an acoustic signal is emitted from an electroacoustic miniature transducer (earpiece, loudspeaker).
  • electro-acoustic devices exists in addition to the direct sound transmission between the handset and microphone nor a second way of signal transmission.
  • the listener can radiate sound through vibrations of the receiver housing.
  • the microphone also absorbs structure-borne noise via its housing.
  • To avoid this parasitic sound transmission is trying to place the earphone and microphone spatially as far as possible from each other in the hearing aid housing. Due to the progressive miniaturization of hearing aids, however, this spatial separation has narrow limits. Therefore, it is attempted to store electroacoustic miniature transducers "floating", so they do not transmit structure-borne noise to housing parts.
  • a storage of a miniature electroacoustic transducer is described with a first and a second elastic support member, wherein the first support member is fixed only in a central region of the front of the housing and the second support member only in a central region of the housing back to the housing of the electroacoustic miniature transducer.
  • an electroacoustic miniature converter with a first housing for encapsulation of a second housing known.
  • an elastic element which is connected to the two housings.
  • the device comprises an electroacoustic miniature transducer for hearing aids with a polyhedral housing module and an elastic holding means.
  • a polyhedral housing module for example, may have the shape of a polyhedron, but the edges are rounded.
  • the holding means is formed with a first material. The housing module and the holding means are designed such that the holding means is connected to only the front end face of the housing module.
  • the first material may be made of rubber and the retaining means may be vulcanized onto the housing module.
  • the first material may consist of a thermoplastic elastomer and the holding means may be sprayed onto the housing module.
  • the advantage is that even elastomers can be easily used.
  • the holding means may be glued to the housing module.
  • the housing module can be formed cuboid.
  • the holding means may have an opening and be connected to the housing module such that the opening of the holding means is brought to coincide with a sound-permeable opening of the housing module.
  • the miniature converter may comprise a membrane and at least one electrical component.
  • the miniature transducer may be a microphone or a speaker.
  • a holding frame for fixing an electroacoustic miniature converter is also specified.
  • the holder frame is formed such that the holding means is fixed in an opening of the holding frame.
  • the advantage of this is that a subsequent installation in a hearing aid housing is easy.
  • the invention also claims a hearing aid with an electroacoustic miniature transducer according to the invention and with a hearing aid housing.
  • the invention claims a hearing aid with an electroacoustic miniature transducer according to the invention, a hearing aid housing and a holding frame according to the invention which can be connected to the hearing aid housing.
  • FIG. 1 shows as a solution of the prior art, a microphone 1, which comprises an elastic holding means 3 and a housing module 2 held therein. With the formed in the holding means 3 opening 5 and the cylindrical sleeve formed around it, the microphone can be elastically and structure-borne sound inhibiting connected to a hearing aid housing.
  • the holding means 3 surrounds the cuboid housing module 2 almost over the entire surface.
  • FIG. 2 is a perspective sectional view of the microphone 1 from FIG. 2 shown. It can be clearly seen that the holding means 3 encloses the housing module 2 almost completely. Due to the finite thickness of the holding means 3 increases due to this construction, the required installation volume by 30 to 50%.
  • FIG. 3 shows a perspective view of an inventive electroacoustic miniature transducer 1, for example a microphone.
  • an elastic holding means 3 may be formed with rubber or with a plastic. It may be vulcanized, molded or glued onto the housing module 2. It can clearly be seen that the holding means is connected exclusively to a surface 4 of the housing module 2.
  • the opening 5 of the holding means 3 is located just above the non-visible opening 6 of the housing module 2, so as not to hinder the propagation of sound.
  • FIG. 4 shows the microphone 1 off FIG. 3 in a perspective sectional view incorporated in a holding frame 7.
  • the mounted on only one surface 4 of the housing module 2 holding means 3 is fitted into an opening 8 of the holding frame 7 such that all openings 5, 6, 8 come to rest one above the other.
  • no disturbing structure-borne noise can be transmitted from the holding frame 7 to the microphone 1 by the elastic suspension of the holding means.
  • the built in a hearing aid housing 9 electro-acoustic miniature transducer 1 from the FIGS. 3 and 4 is in a perspective sectional view in FIG. 5 shown.
  • the electroacoustic miniature transducer 1 is connected to the hearing aid housing 9. Due to the elastic suspension of structure-borne noise of the hearing aid housing 9 is strongly attenuated.
  • the small footprint of the miniature converter 1 according to the invention can be seen.
