Construction and principle of operation of Moving Coil Microphone:

A moving coil microphone functions on the basic principle of Electromagnetic induction. It has a copper wire coil, which when moves in the magnetic field a voltage is generated. Then it is induced in the coil in proportion to its amplitude of vibration, which, in turn, depends on the sound pressure.

A moving coil microphone contains a diaphragm, which is exposed to sound waves. The diaphragm carries a coil placed in the magnetic field.

You will find there are many kinds of moving coil microphones. One of them is the Shure SM58, which is a classic microphone. This is an industry standard microphone designed mainly for live performances. They are strong and yet they do not require high power. They are used in some cases in studios for instrument recordings. Moving coil microphone is also the first choice for the snare drums, and also very popular on electric guitar amplifiers.

Advantages of Moving coil microphone:

• Moving coil microphones are cheap and forceful 
• One of the biggest advantages of a moving coil microphone is the rugged construction of these microphones for rough use. 
• They are also ideal as they have high sound pressure level. It is a strong device and it is impossible to break one without intentionally doing so. 
• They are durable and can withstand pressure of any kind.

Applications of Moving coil microphone:

This microphones are commonly used for various live performances
