WIPO Patent Application WO/2023/188176
Kind Code:

Abstract:
This power generation device comprises a coil, a magnet, and a vibrating plate. The magnet is provided at a position separated from the coil, and is disposed such that pole faces thereof are oriented to the direction of the coil. The vibrating plate vibrates upon reception of sound waves, and has disposed thereon either the coil or the magnet. The vibrating plate changes, by vibration thereof, the relative position of the coil and the magnet and causes a change in magnetic field of the coil, to thereby cause the coil to generate electromotive force, whereby electric power is generated.
