A resonance frequency of the first vibration system is a frequency lower than 1/√2 times a frequency of a vibration input to the first vibration system from the vibrating member. A loss factor of the first spring member of the first vibration system is at least 0.01 but not greater than 0.2.

摘要： A power generator including: a vibration system configured to be attached to a vibrating member; and a power generating element attached to the vibration system. The vibration system is a multiple-degree-of-freedom vibration system that includes a first vibration system having a first mass member elastically supported by a first spring member, and a second vibration system having a second mass member elastically connected to the first mass member by a second spring member. The power generating element is arranged between the first and second mass members, and vibration applied from the vibrating member causes relative displacement of the first and second mass members so that vibration energy of the vibrating member is input to the power generating element. A natural frequency of the first vibration system is different from that of the second vibration system.
