Document Type and Number:
WIPO Patent Application WO/2012/108407
Kind Code:
A1
Abstract:
Provided is a vibration power generation apparatus, which is capable of suppressing reduction of a power generation quantity by suppressing influence of magnetization due to a movable element provided with a permanent magnet, and a shield member composed of a magnetic material. The vibration power generation apparatus is provided with: a coil, which is composed of a conductive material; the movable element, which reciprocates in the coil, and which is provided with the permanent magnet; a guide member, which is composed of a non-magnetic material, and which guides the movable element such that the movable element reciprocates in one direction; the shield member, which is disposed outside of the guide member, and which is composed of the magnetic material; and a viscous material, which is provided between the movable element and the guide member.
