How Sound Is Reproduced

Sound is recorded by converting sound waves into electronic signals that can be processed and stored. Sound is reproduced by converting electronic signals back into sound waves.

A modern speaker produces sound waves in much the same way that a drum does. A drum skin vibrates up and down like a trampoline. As the drum vibrates, it sends a series of compressions and rarefactions through the air across the room. They carry energy to your ears in the form of sound waves.
