VIBRATION POWER GENERATOR

Title:

VIBRATION POWER GENERATOR

Document Type and Number:

WIPO Patent Application WO/2012/127859

Kind Code:

A1

Abstract:

A vibration power generator (100) is a device provided with an oscillating body (10) and a coil (40) arranged around the oscillating body, and in which the oscillating body (10) is moved relative to the coil (40) to thereby obtain an electromotive force. The oscillating body (10) includes a plurality of magnets (20a-20d) arranged in a row in a state in which magnetic-pole faces having the same polarity face each other, end supports (12, 13) for supporting the magnets from both ends in the row direction, and a cushioning material (16). The cushioning material (16) is sandwiched between the end support (12) and the magnet (20c) in a state of being compressed by stress exceeding the repelling force between the magnetic-polar faces of the magnets, and acts against the repelling force to dispose the magnets (20a-20d) in serial fashion without gaps.
