Abstract
A power generation device includes a coil, a magnet, and a diaphragm. The magnet is provided at a position distant from the coil, having magnet pole faces facing a direction of the coil. The diaphragm vibrates upon receiving a sound wave, having either the coil or the magnet being placed. The diaphragm generates power by generating an electromotive force in the coil by a change in a magnetic field of the coil caused by changing a relative position of the coil and the magnet by vibration.
