Abstract
A vibration power generator includes a vibration system attached to a vibrating member. The vibration system includes a first vibration subsystem, and a second vibration subsystem attached to the first vibration subsystem. The first vibration subsystem includes an elastic member attached to the vibrating member, and a first mass member attached to the elastic member. The second vibration subsystem includes a plate spring integral with a piezoelectric element, and a second mass member attached to the plate spring. The first vibration subsystem has a resonant frequency that is substantially equal to a resonant frequency of the second vibration subsystem.
