Title:
VIBRATION POWER GENERATOR
Document Type and Number:
Japanese Patent JP2019122219
Kind Code:
A
Abstract:
To solve the following problem: Conventionally, a vibration power generator, in which a cylinder wound with a coil is vertically retained and a magnet in the cylinder is floated by a repulsion magnet positioned at the lower part of the cylinder to vibrate the cylinder vertically and to generate a voltage at the coil, can generate only a low voltage when a vibration frequency is low.SOLUTION: A small-sized spring and a wheel shaft are used in place of a repulsion magnet, a magnet is suspended from the upper part of the cylinder using a spring with equivalently lowered spring constant and the cylinder is vibrated vertically, thereby generating high voltage even when a vibration frequency is low.SELECTED DRAWING: Figure 1
