HEARING INSTRUMENT WITH AN INTEGRAL INJECTION-MOLDING CASING
First Claim
1. A hearing instrument, comprising:
- a casing;
a frame disposed within said casing, said casing having an integral design and surrounding said frame in five spatial directions;
a fixation device disposed on said frame; and
said casing having in a further spatial direction an assembly opening formed therein dimensioned such that said frame can be pushed into said casing through said assembly opening, said casing further having a fixation opening formed therein in one of the spatial directions perpendicular to the further spatial direction of said assembly opening, said fixation opening interacting with said fixation device disposed on said frame, such that said frame is fixed against sliding out of said casing.

Abstract
A hearing instrument has an integral injection-molding casing. The hearing instrument fixes the internal components in an integral casing that is simple in design, production, and assembly; requires few components; and is easy to handle. Accordingly the hearing instrument contains an integral casing and a frame arranged within the casing. The casing has an assembly opening through which the frame is pushed into the casing. Additionally, the casing has a fixation opening oriented perpendicular to the insertion direction, which fixation opening interacts with a fixation device arranged on the frame in order to fix the frame in the casing. This provides a simple fixation mechanism. The fixation opening can be applied as a bore after the production of the casing, and so the casing has no undercuts and can therefore be produced in an injection-molding method. The fixation device can be embodied as a bolt. The bolt can be integrally molded onto the frame. The bolt can be inserted into the fixation opening by a spring force. In one embodiment, a microphone to be assembled after the frame has been inserted into the casing serves as a bolt.
