Title:
VIBRATION POWER GENERATOR
Document Type and Number:
Japanese Patent JP2018182941
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration power generator arranged to be able to generate a power to vibrations in a wide frequency band without largely increasing the mass and size of the whole.SOLUTION: A vibration power generator 10 is arranged so that a magnet-side unit 30 vibrates through a coil spring 31, and a coil-side unit 40 vibrates through a coil spring 41, whereby a conductive coil 42 crosses a magnetic flux produced by a magnet 32, and an induced electromotive force (output voltage Vout) is generated from the conductive coil 42. In addition, a specific angular frequency ωwhen the magnet-side unit 30 vibrates, and a specific angular frequency ωwhen the coil-side unit 40 vibrates are set to different values.SELECTED DRAWING: Figure 1
