Abstract
A contact transducer assembly for an electromagnetically driven hearing device such as a hearing aid or other audio signal reproducing device worn by a user is described. The contact transducer assembly includes a transducer which is attached to a biocompatible support. This assembly is supported on the tympanic membrane of the wearer by surface adhesion, such that it can be readily inserted and removed in a manner similar to that of a conventional contact lens worn on the eye.
