Hearing aid device
First Claim
1. In a hearing aid device having a housing containing electrical components, which are selected from a microphone, an amplifier, an earphone, a current source, an on/off switch, a control element, the improvements comprising sensor means being sensitive selectively to one of pressure alone and pressure and position, said sensor means being constructed as a film reactive to variable pressures and composed of laminated polymer layers, wherein one layer is connected with interdigitalizing electrodes and the appertaining other layer is coated with a semiconductor material, said sensor means being arranged on a structure element including an outside surface of the housing, the housing, and a structural element disposed within the housing, said sensor means being utilized as switches and regulators.

Abstract
For a simplified construction of a hearing aid device with respect to switch, control and regulating elements, one or more pressure or pressure and position sensors, which are constructed in a film-like structure to react with variable resistance, are composed of laminated polymer layers wherein one layer is coated with interdigital electrodes and the appertaining other layer is coated with semiconductor material. The sensor elements are arranged on either the outside or inside of the housing or can be arranged on a structural member, such as a carrier situated within the housing. The sensor or sensor elements, respectively, can be fashioned as part of the switches or as regulators for the operation of the device.
