Speakers generate sound by electricity. have you ever heard that static on your tv headphones? that's the transmitter trying to connect to the tv. The elecricity travels to the speakers and 'tells' them what to do. it then emits your average sound.

How does a sound wave creator work to generate and propagate sound waves?
