The Microphone picks up sound signals from the environment and transfers them to the
speech processor. The speech processor first picks up the oncoming signals from the
microphone, analyses them and according to the mapping protocols set in the implant,
changes the characteristics of the signal, and send it to the transmitting coil as an
electrical signal. The Transmitting coil then, transfers the electrical signal
electromagnetically to the internal components of the cochlear implant.
The Internal components of the Cochlear Implant include the following:
The Receiving Antenna picks up the electromagnetic signals from the external
transmitting coil and transfers it to the receiver which make sense of the electrical
signal received and thereafter stimulate the electrode array accordingly. The electrode
array stimulates different areas of the Auditory nerve for different types of sounds.
The function of the internal magnet is to create a magnetic coupling between the
internal and the external components.
