A totally implantable cochlear implant system forming a single implantable unit ( 40 ). The unit ( 40 ) has an implantable power source ( 43 ) that provides the power requirements of the implantable unit ( 40 ). The unit ( 40 ) also has an on board microphone ( 42 ) that detects external sounds, such as speech, and outputs acoustic signals representative of the detected sounds. The unit further includes speech processor circuitry ( 44 ) that directly receives the acoustic signals from the microphone ( 42 ) and converts the signals into stimulation signals representative of the detected sounds. An electrode array ( 20 ) suitable for insertion of the cochlea ( 42 ) of an implantee receives the stimulation signals and transmits electrical stimulations to the implantee's auditory nerve ( 9 ).
