Title:
POWER GENERATOR AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2017216775
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power generator capable of suppressing degradation in power generation efficiency when a vibration frequency varies like a vibration by the rotation of a tire.SOLUTION: The power generator, including at least one magnetostrictor 22, further includes: a power generation part 2 for generating electric power on the basis of a change in a magnetic field generated by giving an impact to the magnetostrictor 22; a weight 3 colliding with the power generation part 2; and a retaining member 4 for retaining the weight 3 on the fixed power generation part 2 to be movable. On an outer surface of the power generation part 2 opposing in a movement direction of the weight 3, there is provided a swelling part 211 swelling toward the outer surface of the weight 3 and the power generation part 2 and the weight 3 collide with each other at the swelling part 211.SELECTED DRAWING: Figure 2
