Title:
VIBRATION-TYPE ELECTROMAGNETIC POWER GENERATOR
Document Type and Number:
Japanese Patent JP2009118581
Kind Code:
A
Abstract:

To provide a vibration-type electromagnetic power generator with small friction between a first pipe and a movable magnet and with high power generation efficiency.

The vibration-type electromagnetic power generator 1 is provided with a hollow first pipe 2 which is formed of a non-magnetic material and whose both ends are closed, a power generation coil 9 which is wound to a periphery of the first pipe 2 and in which first solenoid coil 4a to third solenoid coil 4c are arranged and the movable magnet 3 which is disposed inside the first pipe 2 and can move along a winding axis direction of the power generation coil 9. The movable magnet 3 is provided with a hollow second pipe which is formed of the non-magnetic material and whose both ends are closed and first magnet 3a to third magnet 3c sealed inside the second pipe.
