Hearing aid exciting inner ear with implanted electromechanical converter - converts electrical signals supplied to it into transmitted mechanical vibrations and converter is designed as intra-cochlear liquid sound transmitter

摘要

The hearing aid has a liquid sound transmitter (10) designed to produce liquid sound directly in to the liquid of the cochlea. The intra-cochlear liquid sound transmitter is a piezoelectric liquid sound transmitter. The intra-cochlear liquid sound transmitter has a flexible bimorph element. The intra-cochlear liquid sound transmitter is connected directly with a similarly implanted microphone (21) or indirectly across an electronic signal processing unit (24). The implanted microphone (21) has a flexural vibrator or strain gauge strips. ADVANTAGE - Hearing aid is designed with simple construction and allows effective excitation of inner ear.
