The carbon microphone is preferred in public address system.

This will change the electrical resistance between two plates andĬonsecutively output electrical current vary accordingly. This generates varying pressure on carbon granules kept in between. When sound waves are applied on the diaphragm, it causes the diaphragm to vibrate. This carbon microphone consists of two metal plates which are separated by granules of carbon.įrom the two plates one plate is thin and will face the speaker. Crystal microphone which is used on speaker's neck or chest is known as Crystal microphone which is used in front of speaker's mouth It is preferred in sound recording system. Sound waves on pair of surfaces of quartz crystal. In this type, electrical signals are produced by application of variable pressure developed by There are various types of microphone based on their construction and working operation.

It is basically a instrument meant for the conversion of sound waves into equivalent electrical waves.įigure depicts input is acoustic waves and output is taken using two electrical wires. ➨Loudspeaker converts electrical energy to acoustical sound energy. ➨Microphone converts acoustical sound energy to electrical energy. These two audio frequency devices are used together for the sole purpose of
