Claim:
1. A cochlear implant apparatus for active feedback control which is adapted to be located into a human body and configured to detect a sound in each of a plurality of frequency bands, the cochlear implant apparatus comprising: a sensor unit configured to detect vibration according to a sound and generate an electrical signal corresponding to a magnitude of the vibration, wherein the sensor unit comprises a first substrate, a second substrate disposed to face the first substrate, and actuators each of which is configured to receive and react to the generated electrical signal and to control sensitivity according to a magnitude of the sound or a selectivity of the sound detected in each of the plurality of frequency bands, wherein each of the actuators extends in a direction perpendicular to the first substrate or the second substrate, and contacts the first substrate and the second substrate.
