Title:
POWER GENERATOR USING VIBRATION
Document Type and Number:
WIPO Patent Application WO/2011/040265
Kind Code:
A1
Abstract:
Disclosed is a power generator using vibration capable of preventing adhesion of a permanent magnet to magnetic bodies and capable of reliably generating power. Specifically disclosed is a power generator using vibration, which comprises a non-magnetic cylindrical case (1), a coil (2) for electromagnetic induction wound around the outer circumferential surface of the non-magnetic cylindrical case (1), a reciprocable permanent magnet (3) disposed inside the non-magnetic cylindrical case (1), and magnetic leakage preventing magnets (4, 5) disposed at either end of the permanent magnet (3) such that the same poles of the magnets face each other. With this, magnetic lines of force emitted from the end faces of the permanent magnet (3) in moving directions of the permanent magnet (3) are bent in directions orthogonal to the moving directions by magnetic lines of force emitted from the magnetic leakage preventing magnets (4, 5), and the magnetic flux density of the magnetic lines of force in the moving directions is reduced. This prevents the permanent magnet (3) from adhering to metallic contact parts, and allows power generation to be continued.
