摘要： The present invention relates to a cochlear implant apparatus, and more particularly, to a cochlear implant apparatus capable of controlling the sensitivity or selectivity of sound through actuators. In accordance with an exemplary embodiment of the present invention, a cochlear implant apparatus for active feedback control which is inserted into the human body and configured to detect a sound in each frequency band includes a sensor unit configured to detect vibration according to a sound and generate an electrical signal corresponding to a magnitude of the vibration and actuators disposed in the sensor unit and each configured to react to the electrical signal and to control sensitivity according to the magnitude of the sound or the selectivity of a sound detected in each frequency band.
