Definitions for "DYNAMIC MICROPHONE"
This microphone uses a magnet and a coil of wire to produce an electrical signal.
The most common type of microphone used in sound reinforcement. It is basically a speaker in reverse. Sound waves vibrate a diaphragm, which moves a voice coil, which generates an electrical current which is amplified. Dynamic mics are usually cheaper and more rugged than condensor mics, but in absolute terms, are generally sonically inferior to condensor mics.
A microphone where the changing air pressure moves a diaphragm which moves a coil of wire in a magnetic field. An electrical current is produced in the coil of wire that represents the changing air pressure.
