Claim:
1. A vibration power generator comprising: a vibration system attached to a vibrating member; wherein the vibration system includes a first vibration subsystem, and a second vibration subsystem attached to the first vibration subsystem, the first vibration subsystem includes a first mass member and a first elastic member configured to elastically couple the first mass member to the vibrating 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, a resonance amplification factor of the second vibration subsystem is greater than a resonant amplification factor of the first vibration subsystem, a product of a mass of the first mass member and the resonance amplification factor of the first vibration subsystem is greater than a product of a mass of the second mass member and the resonance amplification factor of the second vibration subsystem, and the first elastic member is an elastic rubber body in a form of a block.
