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.

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.

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.
