	Carbon microphones use soundwaves to compress carbon granules between two electrodes, causing variations in current flow.	Dynamic microphones function by moving a coil of wire inside a magnetic field to produce an electrical current in response to soundwaves.	Electret microphones, also known as condenser microphones, use a capacitor for a transducer and generally contain an amplifier circuit.
