http://electromagnets.weebly.com/speakers.html WebHow do audio speakers use magnets? To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. These vibrations are the sound we hear. Speakers often contain large magnets inside of them, as a larger opposing magnetic field creates more vibrations.
