The microphone of the cochlear implant picks up the sound and the speech processor converts the sound waves into a digital code which is then sent to the transmitter coil. The transmitter coil sends the coded signal through the skin to the implanted receiver which is located just under the skin.

How does cochlear implant convert sound?
A cochlear implant tries to replace the function of the inner ear by turning sound into electrical energy. This energy can then be used to stimulate the cochlear nerve (the nerve for hearing), sending "sound" signals to the brain. Sound is picked up by a microphone worn near the ear.
How do cochlear implants work scientifically?
A cochlear implant receives sound from the outside environment, processes it, and sends small electric currents near the auditory nerve. These electric currents activate the nerve, which then sends a signal to the brain. The brain learns to recognize this signal and the person experiences this as "hearing".
How does the cochlear implant allow for perception of sound?
Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve. Signals generated by the implant are sent by way of the auditory nerve to the brain, which recognizes the signals as sound.
Do cochlear implants sound like they do in sound of metal?
And cochlear implants do in fact sound a lot worse than what is depicted in the movie, by almost all accounts. So, the movie presents it factually. I would say that where I'm uncomfortable is with some of the process of getting those implants.
