<p>The present invention relates to a cochlear implant device. When high-level sensorineural deafness occurs due to cochlear diseases, the cochlear implant device is installed in the mastoid to electrically stimulate spiral ganglion cells or peripheral auditory nerves remaining in the cochlea so that a sound is recognized in the cerebral auditory center. The cochlear implant device includes a housing, an oscillating film, an artificial base film, and an electric signal transmitting unit. The housing includes a storage unit for storing a fluid therein and a cover unit disposed at the top of the storage unit to cover the entrance of the storage unit. The oscillating film is disposed in one side of the storage unit and oscillates by means of external sounds. The artificial base film senses the oscillation of the fluid caused by the oscillation of the oscillating film to be differentiated according to frequency bandwith, and differentiated frequencies are converted into electric signals. The electric signal transmitting unit is electrically connected with the artificial base film to transmit electric signals differentiated according to frequency bandwith to the outside of the housing.</p> |
