Dynamic microphones are a type of microphone that use a diaphragm attached to a coil of wire, which moves within a magnetic field to convert sound waves into electrical signals. They are known for their durability and ability to handle high sound pressure levels, making them ideal for live performances and recording loud instruments. These microphones are less sensitive than condenser microphones, which allows them to effectively reject background noise. This characteristic makes dynamic microphones popular for vocals and instruments in both studio and stage settings, such as with singers and guitar amplifiers.
