What is a Microphone
A microphone is a device that translates sound vibrations in the air into electronic signals and scribes them to a recording medium or over a loudspeaker.
Microphones enable many types of audio recording devices for purposes including communications of many kinds, as well as music vocals, speech and sound recording.
Microphones can be standalone or embedded in devices such as headsets and telephones.

How do Microphones work?
The most common type of microphone, the dynamic microphone, uses a coil suspended in a magnetic field that may be attached to multiple membranes for extended frequency response.
Dynamic microphones use electrical energy in the form of induction to produce the audio signal. These microphones are well suited to stage performance.
The microphone capsule contains a small diaphragm connected to a moving coil. When sound waves hit the diaphragm, it vibrates. This causes the coil to move back and forth in the magnet's field, generating an electrical current.
However, how a microphone works ultimately varies depending on its designed purpose.
One of the main considerations, aside from the type of device, is what is being recorded. The directionality of microphones is another consideration in microphone design.
