Title:
VIBRATING GENERATOR
Document Type and Number:
Japanese Patent JP2003199313
Kind Code:
A
Abstract:

To solve the problem in a vibrating generator wherein power genera tion efficiency lowers as input amplitude changes.

This vibrating generator, which converts vibration from the outside into induced voltage in coils by supporting the coils and a permanent magnet so as to be capable of relative movement, comprises the permanent magnet 3, a plurality of coils 1a to 1c which receives at least part of the magnetic flux of the permanent magnet 3, connection parts 24-1, 24-2 which mutually connect all or one of the plurality of coils 1a to 1c, and a control part 25 which controls the connection of the plurality of coils 1a to 1c, based on the induced voltage generated in the plurality of coils 1a. The control part 25 regulates the whole inductance, even when the amplitude from the outside changes, thus, the relative movement of the maximum amplitude can be maintained, thus stabilizing the generated voltage.
