Definition: In the field of audio engineering, a pyrophone is an object that generates sound waves when heated. These sounds are usually produced by a device called a pyrolyzer or a pyrolysis chamber. A pyrophone is typically made from a metal plate with a small hole drilled into it to allow for heating and the emission of sound waves. The heat generated in the plate causes the electrons within the material to vibrate, which produces sound waves that are then transmitted through the air
