Step-By-Step

Let’s take a step by step look into how the microphone process’s sound.

Sound Source

The sound source creates sound wave vibrations in the air.

Microphone Picks up Sound These vibrations of the sound waves

are picked up by a microphone.

Conversion In The microphone converts the

vibrations into an electrical signal.

Your ear does the same thing

Signal Is processed

The electrical signal is processed

Conversion Out

The output device converts the electrical signal back into sound waves

Transduction

This process — converting acoustical energy into electrical energy or electrical energy back into acoustical energy —is called transduction.

Therefore microphones and loudspeakers are examples of transducers.

Dynamic Microphone Dynamic microphones are also called moving-coil microphones.

Inside a Dynamic Microphone  Dynamic Microphone's Working Procedure: 1.      Sound waves hit the diaphragm of the mic. 2.      The very sensitive diaphragm vibrates. 3.      Vibrations move the coil of wire attached to the diaphragm. 4.      The coil is suspended around a magnet. 5.      Magnets have a naturally occurring magnetic field. As the coil

moves, it disrupts the pattern of the magnetic field. 6.      As the coil cuts across the magnetic field lines, an electrical

current is induced in the coil. This is an example of electromagnetic principles.

Dynamic Mic’s

Extremely durable, dependable, and can withstand high sound pressure levels

Versatile because they don't require a power source

Downside: tend to be heavier, larger, and less sensitive than most other types
