Abstract
Apparatus and method for manufacturing an electroacoustic transducer for, for instance, a hearing aid, with a diaphragm arranged in a housing. The diaphragm is attached onto a film or punched from a sheet of material, such that along the circumferential edge of the diaphragm, a free strip of film or a strip of material remains present, in a capillary space between the circumferential edge of the film and the inner wall of the housing, or in a capillary space between the diaphragm and the strip of material, a polymer of a low viscosity is provided to connect to diaphragm with the housing wall. Through the method, the production of the transducer is greatly simplified.
