Sound enters the microphone on the Processor,
1
which transforms the sound and sends the
audio signal to the Light Tip.
The Light Tip converts the audio signal into light
2
and then projects the light wave to the Lens, which
makes direct contact with the eardrum.
3
When the Lens is activated by the light wave,
it vibrates the eardrum gently at different
frequencies—resulting in rich, natural sound.
