Loudspeaker mechanism, illustration. This device converts electrical signals (from the wires at left) into sound waves. The two fixed components are the permanent magnet (centre) and a metal framework (or basket). The magnet surrounds the voice coil. This is an electromagnetic coil that vibrates relative to the magnet when the electric sound signal is sent through it. The coil is attached to a diaphragm (black). As the coil vibrates, it moves the diaphragm, producing air pressure waves (right) known as sound waves. | |
