Abstract
An optical microphone includes a vibrating membrane defining a diaphragm for receiving acoustic signals. An optical element such as a lens is attached for vibrating with the membrane in direct relationship with the acoustic input signals. Fixed fiber optic cables may be placed in alignment with the lens for directing the initial light toward the lens and transmit the directed light from the lens. A single or dual fiber optic geometry may be used with the vibrating lens.
