Microphone:-It is an electrical device for converting, sound impulses into electrical pulsations of similar form. It consists of a thin diaphragm fixed in a position and capable of vibrating in accordance with the sound waves falling on it. These mechanical vibrations of the diaphragm cause similar variations of the diaphragm cause similar variations in current flowing in an electrical circuit. These varying in currents are carried over wire, amplified and fed into a loudspeaker or any sound recording device.
