Dynamic microphones are a type of microphone that uses a moving coil to produce an electrical current. They are often called "moving coil microphones" or "dynamic microphones" for short. Dynamic microphones are relatively simple in design and are known for their durability and versatility. They are often used in live performances, where they may be subjected to rough handling, and in other applications where a rugged, reliable microphone is needed.
Dynamic microphones work by using a diaphragm, which is attached to a moving coil, to convert sound waves into an electrical current. The diaphragm is made of a thin, flexible material that vibrates when sound waves hit it. As the diaphragm vibrates, it causes the coil to move through a magnetic field, which produces an electrical current.
Dynamic microphones are relatively inexpensive to manufacture and are widely available in a range of price points. They are also relatively easy to use, making them a popular choice for beginners and professionals alike.
Despite their simplicity and durability, dynamic microphones are not as sensitive or accurate as some other types of microphones, such as condenser microphones. They also tend to have a slightly limited frequency response, meaning they may not capture the full range of frequencies that some other microphones can. However, they are still widely used in many different applications, including live performances, podcasting, and voiceover work.
