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.
Claims20
A hearing system for imparting audio information to an individual by vibrating the tympanic membrane of the individual, comprising:
- (a) signal producing means for producing signals containing audio information;
- and
- (b) a contact transducer assembly that includes;
- (i) transducer means responsive to said signal to produce vibrations representing said audio information;
- and
- (ii) support means attached to said transducer means, said support means being comprised at least partially of a non-reactive pre-formed biocompatible material having a contact surface of an area and configuration sufficient for manually releasably supporting said transducer means on the external surface of the tympanic membrane.
A method for imparting audio information to an individual by vibrating the tympanic membrane of the individual, comprising the steps of:
- (a) providing a contact transducer assembly responsive to electromagnetic signals;
- (b) manually releasably securing said contact transducer assembly to the external surface of the tympanic membrane to impart vibrations from said contact transducer assembly to the external surface of the tympanic membrane;
- and
- (c) producing audio-modulated electromagnetic signals to vibrate said contact transducer assembly.
