Title:
VIBRATION POWER GENERATOR, ELECTRONIC APPARATUS, AND VIBRATION POWER GENERATION METHOD
Document Type and Number:
Japanese Patent JP2017011879
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration power generator capable of generating a larger power than conventional by using passive energy, and to provide an electronic apparatus and a vibration power generation method.SOLUTION: A vibration power generator includes a vibratable magnet of a rectangular plate body having a magnetization direction parallel with the plate surface, and a coil placed oppositely to one edge side of the magnetization direction of the magnet, and formed by winding a conductor a plurality of times in the magnetization direction. When the magnet vibrates by vibration of a vibration source, the magnetic flux crossing the coil placed oppositely to one edge side of the magnetization direction changes, and an electromotive force is generated in the coil by electromagnetic induction.SELECTED DRAWING: Figure 2
