Title:
POWER GENERATION ELEMENT, POWER GENERATOR AND ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2009118582
Kind Code:
A
Abstract:
To efficiently induce voltage in a coil.
A power generation element 22 includes a non-edge-like cylinder 26 having an elliptical shape by plane view, which is constituted of a non-magnetic material, the coil 28 where conductors are wound to outer faces of corner parts C and D crossing a long axis of the cylinder 26 and a spherical magnet body 30 disposed inside the cylinder 26 so that it can roll. Voltage is induced in the coil 28 by rolling of the magnet body 30 inside the cylinder 26.
