POWER GENERATION DEVICE, POWER GENERATION DEVICE SET, AND POWER GENERATION SYSTEM

摘要

A power generator 100 includes a power generating unit 10 and a supporting member 20 for supporting the power generating unit 10. The power generatimg unit 10 constitutes a two-degree-freedom vibration system including a first vibration system having a coil assembly 40 and a first spring portion 64 for coupling the coil assembly 40 with a housing 20 and a second vibration system having a magnet assembly 30 and a second spring portion 65 for coupling the magnet assembly 30 with the coil assembly 40. The power generating unit 10 is configured so that each of a first natural frequency É 1 of the first vibration system and a second natural frequency É 2 of the second vibration system is in the range of 14 to 42 Hz.
