  • a gooseneck provides for easy deformation of the flexible subassembly from a basic shape into many different end shapes using a room-temperature force that is easily applied by a person.
  • the acoustic unit may be a speaker, so that a sound signal generated by the speaker is passed through the sound conductor to a sound outlet opening of the housing.
  • the sound outlet opening can be arranged on an earmold as part of the housing.
  • the housing may be a housing of an in-the-ear hearing aid (IdO).
  • IdO in-the-ear hearing aid
  • a corresponding ITE has in addition to the prior art with two flexible connecting parts additionally has the advantage that with the sound conductor only a connecting part for attaching the speaker in a Cavity of the IdO is needed. This saves the labor of producing a second connection part and fixing the second connection part in an IdO.
  • a hearing device according to the invention can also be designed as a behind-the-ear hearing aid (BTE) or as a Concha hearing aid.
  • an inventive sound conductor 10 is shown in its basic form.
  • the sound conductor 10 is formed in one piece from metal and has an approximately tubular cavity, which extends from a first end 12 to a second end 14 of the sound conductor 10.
  • the first end 12 of the sound conductor 10 serves to fasten the sound conductor 10 to a loudspeaker 16. It is shaped so that an opening of a cylindrical fastening part 18 made of plastic, whose other opening is fastened to the loudspeaker 16, can be attached thereto with little effort ,
  • the second end 14 of the sound conductor 10 can by means of an unspecified screw on a likewise not shown Housing a behind-the-ear hearing aid (BTE) are attached.
  • BTE behind-the-ear hearing aid
  • the screw is guided through a recess 20 of a fastening component 22 near the second end 14 of the sound conductor 10.
  • the second end 14 of the sound conductor 10 may be formed as a thread. For attaching a threaded second end 14 of a sound conductor 10 to a housing, this is screwed into a corresponding opening of the housing.
  • the sound conductor 10 serves to forward a sound signal emitted by the loudspeaker 16 along a central longitudinal curve 24 of the sound conductor 10 to a sound exit opening of a housing of a BTE located near the second end 14.
  • a fastening hook (earhook) of the BTE with a sound tube can be attached to the sound outlet opening. Via the sound tube, the sound signal can continue to reach a unit of the hearing device mounted in an auditory canal of a user. Since attaching a BTE to an ear of a user and relaying sound signals from the BTE attached to the ear canal are not objects of the present invention, it will not be discussed further here.
  • a sound conductor 10 according to the invention may also be formed in one piece with a sound tube and / or with a fastening hook when a suitable material is selected.
  • a sound conductor 10 according to the invention is suitable for use in various models of a BTE.
  • the different dimensions of the various models of a BTE hardly play a role, since the inventive sound conductor 10 has a gooseneck 26, by means of which the shape of the sound conductor 10 can be adapted to the respective model of a BTE.
  • the gooseneck 26 can, as shown in FIG 2, be accordion-shaped.
