A microphone, also known as a mic, is a sensor that changes sound into an electrical signal, it is also considered as an acoustic-to-electric transducer. This device has numerous applications and is used in tape recorders, telephones, hearing aids, karaoke systems, audio engineering both recorded and live, motion picture productions, megaphones, the FRS radio, broadcasting on radio and television, speech recognition, for recording voices in computers and VoIP. It is also used for purposes non-acoustic like knock sensors and ultrasonic checking.
Most of the microphones in use today are dynamic microphones which means that they use electromagnetic induction, condenser microphones which means that they use capacitance change, light modulation so that it can generate, from a mechanical vibration, an electrical voltage signal or piezoelectric generation microphones.
Types of microphones:
Lavier Microphones: These types of microphones are made for hands-free function. These microphones are small and can be worn on the body. It was originally supposed to be worn around the neck but these days it is fixed onto clothing with a pin, magnet, clip or tape. The wires of these microphones can be hidden in pockets or by clothing.
Stereo Microphone: This type of microphone is used for field recordings or for broadcast uses. It is used where it would be unfeasible to set-up two separate condenser mics for stereophonic recording.
Wireless Microphone: These types of microphones transmit audio, not through cables but as optical or radio signals. These microphones send signals to a receiver that is nearby, and connected to the sound system, with the help of FM radio transmitters. However, if the receiver and transmitter are in close proximity, the wireless microphone can also use infrared waves.
Noise-canceling Microphone: These microphones are meant for noisy surroundings and are directional in design. These mics are used in live events like stage concerts and also in the cockpit of an aircraft. In the cockpit, these mics are set on headsets like boom microphones.
These are just a few types of microphones that are in use these days. Microphones are also extremely important during video shoots so as to capture the sound as well as the moving images.

Types of microphones:
- Omni-directional or non-directional microphones
- Unidirectional microphone
- Cardioid microphone
- Bi-directional microphone
- Shot-gun microphone
