Title:
VIBRATION GENERATOR
Document Type and Number:
WIPO Patent Application WO/2012/014649
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electromagnetic induction type vibration generator, wherein a reduction in power generation efficiency is minimized by reducing the kinetic energy of permanent magnets. The permanent magnets (111) are inserted in a core section (122) disposed at the center of a cylindrical member (2) of a magnetic material, and immobilized, and movable coils (135) are disposed in bobbin cases (131) along the periphery of the permanent magnets (111). Power is generated by forcing the coils (135) to intersect a magnetic flux generated from the permanent magnets (111) toward the cylindrical member (2).
