Document Type and Number:
Japanese Patent JP2021191021
Kind Code:
A
Abstract:
To provide a power generation device capable of generating a power in a high performance as compared with a prior art.SOLUTION: A power generation device comprises: a non-magnetic yoke of which one end is vibrated as a free end by an external force; a magnetostrictor receiving a stress from the non-magnetic yoke so as to be fixed to one face of the non-magnetic yoke; a coil wound to the magnetostrictor; a first magnet applying a magnetic field to the magnetostrictor; a magnetic yoke in which one end is connected to an end part which is not the free end of the non-magnetic yoke, and which transmits the external force to the non-magnetic yoke; a second magnet fixed to the neighbor of the free end of one curve face of the non-magnetic yoke; a third magnet fixed to a space from the second magnet with a gap; a fourth magnet fixed to the neighbor of the free end of the other curve face of the non-magnetic yoke; and a fifth magnet fixed to a space from the fourth magnet with the gap. Any one of a pair of the second and third magnets and a pair of the fourth and fifth magnets is arranged so that the same poles are opposite, and the other pair is arranged so that different magnetic poles are opposite.SELECTED DRAWING: Figure 1
