Definitions

  • the present invention relates to a hearing device comprising a housing, a receiver arranged in the housing, and a sound conductor, through which sound from the receiver is guided out of the housing.
  • a hearing device is understood here to mean any sound-emitting device which can be worn in or on the ear, in particular a hearing device, a headset, headphones and the like.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (ITE), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • ITE in-the-ear hearing aids
  • ITE in-the-ear hearing aids
  • ITE in-the-ear hearing aids
  • ITE concha hearing aids or canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated into the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular the signal processing unit 3 is effected by a likewise integrated into the hearing aid housing 1 battery. 5
  • a receiver is provided within the housing, which generates the amplified sound for the hearing aid wearer.
  • the sound must be transmitted by the listener out of the housing of the hearing aid to the auditory canal of the hearing aid wearer. This transmission path requires several sound channels. Some of these sound channels are inside the case and some outside the case of the hearing aid. Outside the hearing aid housing, for example, there is a sound channel in the carrying hook of the hearing device and a sound channel in the sound tube from the carrying hook to the auditory canal.
  • Within the hearing aid housing are sound channels in the earpiece, from the earphone to an adapter to which the carrying hook is attached, and in the adapter itself.
  • the tube from the handset to the adapter is usually routed under a microphone and thus usually runs at the bottom of the hearing aid housing, which has the largest housing cross-sectional curvature.
  • For the tube or the hose must be provided according to a lot of space under the microphone.
  • the object of the present invention is to reduce the volume of a hearing device and in particular of a hearing aid.
  • a cover piece is inserted into the housing of the hearing, so that a sound channel between the listener and a Schallleit Culture forms, which is bounded laterally by the housing and the cover piece.
  • the housing is used as a sound channel wall.
  • the housing interior is better utilized, there is no unused space in the housing around a sound channel around, and the housing can be made smaller accordingly.
  • the housing may have approximately a D-shape in cross section, and a housing section with the greatest cross-sectional curvature may form the sound channel.
  • This D-cross-sectional shape is common in behind-the-ear hearing aids as it is adapted to the anatomy of the outer ear.
  • no microphone can be installed in the area of the greatest cross-sectional curvature, so that this area is offered for the sound channel and can now be fully utilized by the cover piece.
  • the cover piece has a substantially platelike shape.
  • the cover piece is thus easy to manufacture and can also be used as a support for a microphone.
  • the cover piece may have an opening as an input of the sound channel. This results in a defined opening of the sound channel, which does not yet have to be considered when spraying the housing.
  • the cover piece To the opening of the sound channel can be formed on the cover piece a nozzle on which a receiver neck of the listener is inserted.
  • the cover piece additionally fulfills the function of an adapter.
  • the sound conductor at the other end of the sound channel may be an adapter that forms a sound connection between a sound conduit of a carrying hook attached to the housing and the sound channel in the housing.
  • the adapater has the functionality of both the sound conduction and the mechanical attachment.
  • a microphone may be arranged in the housing, wherein the sound channel is passed under the microphone.
  • the peak, i. H. the narrowest end of the hearing aid housing are spatially best utilized.
  • the sound channel can be hermetically sealed from the interior of the housing by the cover piece.
  • the cover piece may be glued or welded to the housing.
  • connection techniques are particularly suitable for achieving an airtight sound channel.
  • the said hearing device as a behind-the-ear hearing device train.
  • the inventive technique smaller hearing aids can be built so that their acceptance increases.
  • FIG. 2 a section of a housing 10 for a BTE hearing aid is reproduced.
  • the housing 10 is shown open at the top.
  • an adapter 11 can be inserted, which serves as Schallleit Culture to direct the sound generated in the housing to the outside. For this he has a corresponding hole 12th
  • FIG. 2 Also shows FIG. 2 a cover piece 13 that can be inserted into the housing 10.
  • the cover piece 13 has approximately the shape of an elongate plate. At one end, a nozzle 14 is provided, through which the outwardly conductive sound is passed. At the other end of the cover piece 13 is a connection point 15 to produce a soundproof connection to the adapter 11 (see FIG. 3 ).
  • the housing 10 has a shape in cross-section which is approximately D-shaped.
  • the lower portion 16 of the Housing a much greater curvature than the upper portion 17.
  • the lower portion 16 is turned when worn behind the ear down and lies in the gap between
  • FIG. 3 The front section of the BTE hearing aid is shown in almost fully assembled state in longitudinal section.
  • the adapter 11 is inserted.
  • a carrying hook 18 is mounted, which itself has a sound channel 19 from the adapter 11 to its tip.
  • a receiver 20 is used in the housing 10, which generates the amplified sound. He has at its output a earpiece 21 through which its output sound is passed.
  • FIG. 3 the cover piece 13 is shown in its final mounting position. Between the housing inner wall in the region of the lower portion 16 and the cover piece 13, a sound channel 22 is formed. The sound channel 22 extends over the entire width in the housing interior below the cover piece thirteenth
  • a D-shaped sound channel instead of a sound tube or sound tube (round or rectangular cross-section) is obtained within the housing 10 in the present case.
  • the cover piece 13 must be inserted into the housing 10, for example by ultrasonic welding or gluing.
  • the space in the hearing aid housing can be better utilized with the same channel cross-section, so that the housing 10 or the hearing aid can be made smaller overall.
  • the cover piece 13 is formed platelet-shaped. In principle, however, it can also assume any other shape in order to form the wall of the sound channel 22.
  • the cover piece 13 can take on a further function, namely that of a carrier for a microphone of the hearing aid. Such a microphone is in FIG. 3 for the sake of clarity not shown, but can be placed in the space above the cover piece 13.
