The device that converts sound into an electrical signal is called a microphone. It captures sound waves and converts them into an electrical signal that can be amplified, recorded, or transmitted.
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.
Detector converts optical signal to electric signal
-- microphone -- piezoelectric crystal -- dynamo
electrical signal can be converted to an optical sigal by using a LED or SOA(semiconductor optical amplifier). LED is the cheaper option but have the drawback of larger linewidth. Typically used for LAN (local area network). SOA produces an optical signal mostly by direct modulation tecnique .
This is an electronic device which converts electrical signal into a digital signal.
A microphone is an acoustic-to-electric transduceror sensor that converts sound into an electrical signal.
Microphone can do this job.
A microphone.
the difference between both are: Primary transducer:The Mechanical device which converts physical quantity to be measured into a mechanical signal. Secondary tranducer:The Electrical device which converts this mechanical signal to the electrical signal.

Familiar examples include audio and video signals resulting when a microphone converts voice or a video camera converts an image into an electrical signal. By contrast, the digital signal takes only a few discrete values. In the binary representation
