Microphone
An INPUT transducer that converts sound waves into an equivalent electrical signal of the same frequency. (A voltage is produced proportional to the air pressure variations).

Moving Coil Microphone

Moving coil microphones are similar in structure to moving coil loudspeakers but much smaller and more delicate.

When sound hits the microphone, a paper cone inside the structure is moved by the sound waves. This in turn moves a coil. The coil is suspended in a strong magnetic field so when it moves, voltages are induced. These voltages are proportional to the coil movement. This in turn is proportional to the incoming sound waves.
