Abstract
A system for enhancing a patient's hearing using electrically driven sound transducer, i.e., a speaker, implanted in the patient's middle ear cavity. More particularly, the speaker is implanted in the middle ear cavity inward of the tympanic membrane and oriented to direct sound energy toward the ossicles or the round window. In a first arrangement, the speaker functions to vibrate the ossicles and thus, via the oval window, actuate the perilymph in the cochlea. In an alternative arrangement, the speaker functions to actuate the cochlea via sound injected into the round window.
