1. Sound is energy.
2. Energy can be converted from one form to another.
Picture a microphone. A simple device that has a permanent magnet, a coil of copper wire, and a thin diaphragm.
The copper wire is coiled around a thin cylinder of paper so that it encircles the magnet without touching it.
That coil is attached to the diaphragm and positioned over the magnet.
When sound hits the thin diaphragm, the diaphragm vibrates moving the the copper coil back and forth over the magnet. This action creates electrical impulses in the coil. This is energy conversion.
To see this in action, take a speaker apart. A microphone and a speaker work on the same principals only in reverse.
If you connect a volt meter to the leads on a speaker and move the cone, you'll see the meter register small amounts of electricity.

∙ 15y agoThe most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.

∙ 13y agoIn most devices, including headphones, earphones, radios, televisions and computers, electrical energy is transformed to sound energy by an electrodynamic loudspeaker. A speaker consists of a coil of wire suspended in a magnetic field. Changes in the current in the wire cause motion of the coil--the same principle of conversion of electrical to mechanical energy first demonstrated by Michael Faraday in 1821. The electrodynamic loudspeaker is actually a specialized form of electric motor. Like other electric motors, an electrodynamic loudspeaker can be also used in reverse--as a generator--to transform sound energy into electrical energy.
