  • Patent number: 8331597
    Abstract: In order to connect a hearing device to a carrying hook, a connecting element is used, which has to satisfy high demands with regards to its precision and stability. To ensure this, the connecting element is designed as a powder injection molded part, in particular as a ceramic injection molded part or metal part, which is manufactured in a ceramic injection molding process or a metal injection molding process.
    Type: Grant

  • Publication number: 20120250923
    Abstract: An auditory canal insert is to be produced which can be manufactured simply and cost-effectively and which is less susceptible to dirt, especially cerumen. To this end an auditory canal insert is proposed which has an at least essentially tubular inner section, an outer section lying at least in some area against a user's auditory canal wall when the device is being worn and a filter element, especially a cerumen-protection and/or attenuation element, in which the filter element is initially manufactured as a separate component and subsequently connected by an insert molding process in one piece with the inner section. For the filter element this thus enables a broad spectrum to be covered in respect of its acoustic and mechanical filter characteristics.

  • Patent number: 8275163
    Abstract: A battery compartment for a behind-the-ear hearing device includes a battery compartment body having a battery receiving space for accommodating a battery and at least one latching element for locking to a hearing device housing. The latching element and the battery compartment body are formed of different materials and the latching element is disposed in a holding device in the battery compartment body. A behind-the-ear hearing device with a latching element and the use of polyoxymethylene for manufacturing the latching element, are likewise provided. As a result of the separation of the latching element and the battery compartment body and the use of different materials, a switching and locking function can be optimized and the wearing quality can be improved.

  • 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.

  • 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.
