A Speaker works in reverse to a microphone. As a Microphone detects pressure waves in the air (we call sound); a speaker generates pressure waves that your ears can hear. Most speakers on robots allow them to generate different noises to indicate or provide some additional level of feedback.

Inside a speaker exists a diaphragm that has a magnet attached to it. Surrounding this magnet is a larger coil of wire. As current is passed though the coil of wire it generates a magnet field that pulls or pushes the magnet up or down and causes the diaphragm to distort. These quick distortions generate fluctuations in air, and are what we hear as sound.

Pre-programmed electronic signals can be sent to the speakers to generate noises or frequencies as notes in a song.
