that convert sound into an electrical signal using electromagnetism

Dynamic microphones are mics that convert sound into an electrical signal using electromagnetism.

a small loudspeaker used in reverse

Essentially, a dynamic microphone is a small loudspeaker used in reverse.

one in which audio signal is generated by the motion of a conductor within a magnetic field

A dynamic microphone is one in which audio signal is generated by the motion of a conductor within a magnetic field.

a coil of wire in a magnetic field

A dynamic microphone is simply a coil of wire in a magnetic field and will pick up the most simple of sound waves.

the most common type of microphone

The dynamic microphone is the most common type of microphone.

a magnet vibrating inside a coil

As we discussed in the September issue, a dynamic microphone captures sound using a magnet vibrating inside a coil and is designed to pick up sound close to the input source and avoid unwanted sounds from other sources.

as a karaoke microphone

A dynamic microphone (also known as a karaoke microphone) is satisfactory but provides a softer signal than a condenser microphone (also known as a powered microphone).

microphones that work essentially like a speaker in reverse

Dynamic microphones (sometimes called moving coil mics) are microphones that work essentially like a speaker in reverse.

Beta 57A Microphone

Beta 57A Microphone is a dynamic microphone that provides optimal warmth and presence.

a common saying that dynamic microphones just have no maximum SPL

a dynamic microphone is a common saying that dynamic microphones just have no maximum SPL.

a good choice for a wired karaoke microphone

Dynamic Microphone is a good choice for a wired karaoke microphone and you can get a 3 pack with a protective hard case making this great value.

the more common microphone used today

A dynamic microphone is the more common microphone used today.

the simplest mic design

Dynamic microphones — sometimes called moving–coil mics — are the simplest mic design.

a thin membrane attached to a coil

A dynamic microphone has a thin membrane attached to a coil.

one that is generally used for performing live because of one's stability and durability

A dynamic mic is one that is generally used for performing live because of one's stability and durability, while a condenser mic is more fragile and commonly used for recording in professional studios.

pressure receivers that sense changes in air pressure

Dynamic microphones are pressure receivers that sense changes in air pressure.
