  • Patent number: 8094849
    Abstract: A mechanically more stable and more complexly molded sound channel is to be provided for a hearing apparatus. Provision is made to this end for a sound channel, which has three sections in the longitudinal direction, the middle section of which has a different curvature or a larger internal circumference than the two outer sections, to be produced by injection molding. Here a negative of the sound channel is fixed within the injection molded form, with the negative consisting of a first material. The injection molded form with a second material, which has a higher melting point than the first material, is then extruded. The negative is then melted or burnt out of the cast sound channel. Very complex sound channel forms, for instance also with cavities and branching, can be realized in this way.

  • Patent number: 8077895
    Abstract: A behind-the-ear hearing aid is provided, with an elongated housing and an audio shoe, which is affixed to an end face of the housing in such a way that it can be removed, and a coupling device, with which the audio shoe is coupled to the housing by a sliding movement parallel to the end face of the housing. In addition, affixed to the audio shoe there is a securing device which includes a slider which can be moved crossways relative to the direction in which the audio shoe slides, which in a first position permits the sliding movement of the audio shoe and in a second position prevents the sliding movement. It is thus possible to mount the audio shoe on the hearing aid housing, and to make any necessary contacts, with a double linear movement which is easy to realize.

  • Publication number: 20110249848
    Abstract: The invention relates to a hearing aid with an audio-shoe interface, an associated audio shoe and a hearing-aid system comprising a hearing aid and an audio shoe. A basic idea of the invention consists of a hearing aid with a housing, in which an undercut and an abutment are provided. The abutment is arranged opposite to the undercut. Undercut and abutment are embodied such that a retaining lug of an audio shoe can be inserted into the undercut by a rotational movement. The abutment is embodied such that a retaining lug inserted into the undercut can only be removed from the undercut again by a rotational movement in the opposite direction. Furthermore, provision is made for a lock that prevents a rotational movement of an inserted audio shoe in the opposite direction. When the electrical contacts between audio shoe and hearing aid are disposed in the undercut, these too are hidden from view and well protected against external influences.

  • Publication number: 20110188689
    Abstract: A hearing apparatus, more particularly a hearing aid, generally requires sound or electrical signals to be conducted from a housing, worn outside of an auditory canal of a user, to an earpiece which has been inserted into the auditory canal. An appropriate conduction device often has a soft tube. The tube must be fixedly connected to the earpiece so that the latter can be pulled out of the auditory canal using the tube. Nevertheless, the connection between the tube and the earpiece is made detachable by an appropriate plug so that the earpiece can be cleaned. The plug is attached as securely as possible to the soft tube. One end of the tube and a region of the plug may be encapsulated by a material by insert molding or the tube and the plug may be welded together. A method for producing a conduction device is also provided.

  • Patent number: 7971337
    Abstract: The production of a hearing aid device can be simplified by the use of a microphone module with a plurality of microphones. To attach and electrically contact the microphones, the invention provides a microphone carrier with three-dimensionally directed conductor traces in MID technology. In a complicated microphone arrangement with a plurality of microphones, a single microphone module can thereby be used on which all microphones of the hearing aid device are attached and electrically connected.

  • Publication number: 20110135127
    Abstract: A behind-the-ear hearing device has a hearing device housing and a user-operable switch. At least two microphones are disposed below the switch in the hearing device housing, and the housing is formed with first sound openings that are arranged directly below the switch. The switch is preferably a rocker switch. The microphones can be positioned below a switch in a space-saving fashion and the installation space of the hearing device housing can thus be used optimally.

  • Publication number: 20100220882
    Abstract: A hearing device with a replaceable shell concept is configured such that the visible parts of a housing can be replaced quickly and easily. Therefore, it should be possible to replace a shell using few manual operations. The novel hearing aid has an acoustics unit that can be inserted into a shell part, wherein the acoustics unit has a projection engaging into a correspondingly shaped region of the shell part when the acoustics unit is in the inserted state. As a result of the engagement of the projection into the region, a movement of the acoustics unit in a direction out of the shell part is automatically blocked. Additionally, the acoustics unit can be fixed in the shell part by a pin.

  • Publication number: 20090080680
    Abstract: A hearing apparatus is provided with a housing including a first housing mounting element and a control element that is mounted rotatably in the first housing mounting element via a control mounting element. Furthermore the housing has at least one second housing mounting element so that the control element can be optionally mounted rotatably in the first housing mounting element or in the second housing mounting element. Thus the control element can be actuated in a desired position.

  • Publication number: 20090022348
    Abstract: A hearing apparatus with a housing, which has a receiving surface for attaching an audio shoe is provided. The receiving surface has at least one first fastening facility, to which a corresponding second fastening facility of the audio shoe can be fastened such that the audio shoe can be attached to the hearing apparatus in a linear and essentially perpendicular fashion in respect of the receiving surface. An electrical and mechanical connection between the hearing apparatus and the audio shoe can thus be established in a simple fashion. According to a further aspect of the invention, a corresponding audio shoe is provided which can be attached to a hearing apparatus.

  • Publication number: 20090022347
    Abstract: A hearing apparatus allowing a user to reliably switch the apparatus on and/or off includes a battery compartment for a battery and an actuation element disposed at the battery compartment for switching the apparatus on and/or off. A contact element has a contact point and taps an electric potential on the battery with the contact point when the actuation element is in a first position. The actuation element, in a second position linearly displaced from the first position, lifts the contact element at a lifting section of the contact element being different from the contact point, to remove the contact point of the contact element from the battery. Thus, the contact point of the contact element only contacts the battery and no additional material, preventing materials from being scratched and an electric circuit from being interrupted and ensures that an even, grippable surface of the actuation element is always available.

  • Publication number: 20080212813
    Abstract: With housing elements of a hearing device which are fastened to a frame for accommodating internal components of the hearing device, the use of a large number of additional parts is problematic because of the risk of losing parts. In accordance with the invention a snap-on fastening means is used to fasten a housing element to the frame of the hearing device, with an opening being provided in the housing element and the frame for accommodating the snap-on fastening means.
