Definitions

  • the invention relates to a hearing device with a housing and a guide element, with which sound or electrical signals from the housing to another element of the hearing device, e.g. an ear piece, can be passed.
  • the guide element is held by a coupling element on the housing.
  • the coupling element is reversibly detachably connected to the housing, i.
  • the coupling element can be detached from the housing without damage and also attached to it again.
  • hearing device is understood in particular to mean a hearing device. In addition, however, the term includes other portable acoustic devices such as headsets, 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 (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • IDO in-the-ear hearing aids
  • ITE 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 in 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. If necessary, the sound is transmitted via a sound tube, which is fixed in the ear canal with an earmold, to the eardrum of the device wearer.
  • 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
  • the sound tube of a hearing aid is a guiding element for conducting sound. With him, the sound generated by the receiver 4 can be selectively transmitted into the ear canal. Often a connection of the sound tube with the hearing aid housing 1 via an earhook is possible. At this the hearing aid housing 1 can then be hung behind a pinna of the device carrier.
  • the ear hook acoustically couples the sound tube to a sound exit opening of the housing 1. It is thus a coupling element with which a sound generated by the earpiece 4 can be directed into the sound tube.
  • a much smaller coupling element is used to connect the sound tube to the hearing aid housing instead of an ear hook.
  • the coupling element of a hearing aid and the sound tube attached thereto must be able to be removed from the hearing aid housing in order to clean the sound tube or replace it with a new sound tube.
  • the removal should be done by the wearer himself. Therefore, the connection between the coupling element and the hearing aid housing must be solved as easily as possible and restored.
  • the coupling element must not then be released from the housing when the equipment wearer, for example, by mistake accidentally brushes along the sound tube and thereby pulls on the coupling element.
  • the coupling element is screwed onto a socket which protrudes from the housing. Through this neck and sound, which is generated by a listener inside the housing, can get out of the housing.
  • the sound pipe can have an external thread onto which the coupling element can be screwed.
  • a disadvantage of this connection is that after repeated screwing and unscrewing of the coupling element wears a thread in the interior of the coupling element, so that the coupling element can not connect acoustically sealed with the housing. This can lead to an unwanted feedback of the sound generated by the listener in a microphone of the hearing aid.
  • parts of the thread can detach from the coupling element and reach the sound socket or the sound tube. Then a transmission of sound into the ear canal is impaired.
  • a hearing aid with an external receiver the sound is generated directly in the ear canal of the device carrier by an in-the-ear speaker.
  • this hearing aid no sound tube, but a cable is provided between an outside of the ear canal housing of the hearing aid and the speaker. This cable serves as a guide for electrical signals that are transmitted from the housing outside the ear canal to the speaker in the ear canal.
  • a cable is meant here an arrangement of one or more wires with associated insulation.
  • a cable for an in-the-ear speaker must be reversibly releasably connected to the outside of the ear canal housing. As with a sound tube needs This connection can be easily solved by the device carrier itself. Nevertheless, it must not be solved by itself with a slight pull on the cable.
  • a corresponding coupling element for connecting the cable to the housing must not wear too quickly, because the coupling element would otherwise sit too loose on the housing and then sporadic interruptions of electrical connection between contacts of the coupling element on the one hand and contacts of the housing would come.
  • Such contacts may also be located inside the housing of the hearing aid. In such internal contacts dirt can for example pass through a recess in a shell of the housing, in which a switch of the hearing aid is used.
  • the object is achieved by a hearing device according to claim 1.
  • the invention also includes a line arrangement for a hearing device according to claim 8.
  • Advantageous developments of the hearing device according to the invention are given by the dependent claims.
  • the hearing device comprises a housing and a guide element for conducting sound and / or electrical signals.
  • the guide element is held by a coupling element on the housing.
  • This coupling element is reversibly releasably connected to the housing.
  • the connection, via which the coupling element is connected to the housing in this case comprises a dovetail connection.
  • a dovetail joint can be provided, for example, in that on one of the two components, for example the housing, an extension is formed, which is undercut on at least one side. In the other component can then be provided a recess through which this component can be postponed on the extension. The undercut results in a positive connection in a direction transverse to the thrust direction.
  • the hearing device according to the invention is further developed in an advantageous manner by the coupling element is pushed for connection to the housing transversely to an extension direction, in which the guide element extends away from the coupling element. It is particularly advantageous if the coupling element is pushed for connection to the housing perpendicular to this extension direction. This results in the advantage that the coupling element is not released from the housing when the device carrier accidentally pulls on the guide element.
  • a further advantageous embodiment of the hearing device according to the invention results when a housing-side component the dovetail joint is formed integrally on a shell part of the housing. Then, the shell part and the housing-side component of the dovetail connection can be produced in one step. This has the advantage that the costs for producing a hearing device according to the invention can be reduced.
  • the housing or the coupling element has a base, which is a component of the dovetail connection
  • a base can for example form that extension in the dovetail joint, which has the undercut already described.

  • the front side is such a side of the base, in which a surface normal facing away from the housing.
  • the housing and the coupling element in the dovetail each having at least one electrical contact for transmitting an electrical signal. Then, the contacts to be brought into contact with the signal are pressed together particularly well. Thus, it is ensured in an advantageous manner that an electrical connection also comes about when, for example, dirt is on the electrical contacts.
  • This development of the hearing device according to the invention is based on the recognition that the housing and the coupling element are held together particularly firmly in the region of the dovetail joint.
  • a guide element can be provided that it is designed both for conducting sound and for conducting electrical signals. Then, for example, in addition to a sound, a control signal for an active element also leads into an auditory canal.
  • Such an active element may, for example, be an earpiece which can be adapted in its shape by means of an actuator.
  • This line arrangement comprises a guide element for conducting sound and / or electrical signals and a coupling element, via which the guide element can be detachably connected to a housing of the hearing device.
  • a line arrangement can be produced independently of the rest of the hearing device.

  • the ear hook 14 is a coupling element for enabling the reversibly releasable connection of the sound tube 16 to the housing 12.
  • the sound tube 16 is limited in its flexibility, since a part of the connection region is inserted in a recess of the ear hook 14. At an opening of the ear hook 14 formed by the recess, the sound tube 16 extends from the ear hook 14 along an extension direction 21 away from the ear hook 14.

  • the ear hook 14 When the ear hook 14 is pushed onto the base 28, a positive connection of the base 28 with the ear hook 14 with respect to the direction of extension 21 results in the region of the undercut 34. Then, the sound tube 16 is pulled so that a force is exerted on the ear hook 14 the extension direction 21 acts, the ear hook 14 is held against the force of the base 28 to the housing 12. The ear hook 14 is still easy for a user of the hearing aid to remove from the housing 12. This requires the user simply push the ear hook 14 away from the base 28 counter to the direction of thrust 36.

It can be seen that the ear hook 14 has an undercut 48 in the region of the recess 46. The ear hook 14 can be pushed onto the housing 12 along the direction of thrust 36 on the base 28 such that the base 28 of in FIG. 4 slides left into the recess 46.
  • the base 28 can be pushed into the recess 46 until it abuts a wall 50 of the ear hook 14. Then, the base 28 completely fills the recess 46 out.
