Speakers - Electromagnets in Daily Life

On a basic level, a speaker is the opposite of a microphone. It takes an electric signal and transforms it into sound waves that humans can hear. However, the underlying technology is more complicated than this. There are three main parts of a speaker: the diaphragm, the voice coil, and the magnet. The diaphragm is a cone shaped structure.
