A programmable hearing aid circuit is programmed by making electrical connections between contacts that are connected to the circuit. The connections are made by conductive region(s) located on the body of the battery door.

Door-dependent system for enabling and adjusting options on hearing aids

A support structure for use in a hearing aid has a plurality of support stations where circuit boards may be mechanically supported. The structure is mounted to the faceplate of the aid in front of the opening where the battery is inserted. The support structure is formed by two assemblies; each assembly is made up of a circuit board and a battery terminal.

Modularized hearing aid circuit structure

One microphone of a binaural Completely-In-Canal ('CIC') hearing aid is located at the distal end of the retrieval line. This reduces coupling between the microphones and receiver. Additionally, by locating the microphone at the distal end of the retrieval line, the faceplate need not be enlarged.

Binaural hearing aid with integrated retrieval line and microphone

A system for programming hearing aids uitilizes a multi-electrode programming strip. The strip is inserted into the aid through a narrow slot in the faceplate; the slot is bounded by the faceplate and by one of the edges of the battery door. When the door is closed, the strip (and the electrodes thereon) is urged against corresponding terminals that are located inside the aid.
