Hearing instrument with an integral injection-molding casing

摘要

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; requires few components; and is easy to handle. 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. The casing has a microphone opening oriented perpendicular to the insertion direction, which microphone 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 microphone opening can be applied as a bore after the production of the casing, and therefore be produced in an injection-molding method. The fixation device can be embodied as a microphone. The microphone can be inserted into the microphone opening by a spring force.

主权项

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 microphone opening formed therein in one of the spatial directions perpendicular to the further spatial direction of said assembly opening, said microphone opening interacting with said fixation device disposed on said frame, such that said frame is fixed against sliding out of said casing, said fixation device having a microphone being introduced into said microphone opening and removable from said microphone opening and said microphone being kept therein by a spring force; and an elastic device applying the spring force, directed in a direction of said microphone opening, onto said frame.
