Abstract

An electromechanical transducer for an implantable hearing aid, such as a partial middle ear implantable (P-MEI) or total middle ear implantable (T-MEI) hearing aid system. The invention comprises at least one piezoelectric element (255) proportioned for mechanically coupling to a middle ear (35) only through an auditory element in the middle ear, such as the tympanic membrane (30), malleus (40), incus (45), stapes (50), or in the inner ear, such as the oval window, round window, vestibule, or semicircular canals. The invention need not be secured to a temporal bone. Inertial masses and a carrier are optionally provided to assist in sensing or producing mechanical vibrations. The carrier is optionally hermetically sealed. Superpositioned individual frequency responses optimize an overall frequency bandwidth.
