How a Dynamic Microphone Works Mics Explained - Part 1 of 2

Dynamic mics

Dynamic microphones are one of the most common types of microphone. Dynamic microphones are versatile and ideal for general-purpose use. They use a simple design with few moving parts. They are relatively sturdy and resilient to rough handling. They are also better suited to handling high volume levels, such as from certain musical instruments or amplifiers. They have no internal amplifier and do not require batteries or external power.


How it works

Dynamic mics consist of a diaphragm suspended in front of a magnet to which a coil of wire is attached. The coil sits in the gaps of the magnet. Vibrations of the diaphragm make the coil move in the gap causing an AC to flow. Coils of wire are used to increase the magnitude of the induced voltage and current.

Where it's used

Dynamic microphones are generally used for live events such as concerts. This is due to the fact unlike the condenser microphone, it has a low sensitivity and can handle a lot louder environments. The sound pressure of the singer’s voice overpowers any of the surrounding music to allow them to be heard, even over the loudest concerts.
