Title:
VIBRATION POWER GENERATOR
Document Type and Number:
Japanese Patent JP2019115200
Kind Code:
A
Abstract:
To provide a vibration power generator capable of suppressing vibration damping.SOLUTION: A vibration power generator 1 generates electric power by moving a magnet 11 which received vibration. The vibration power generator 1 includes: a housing 2; a spring 3 supported by the housing 2 and suspending the magnet 11 inside the housing 2; and a rectifier circuit 15 that can be fixed to a bottom surface facing the magnet 11 of the housing 2 and that includes a magnetic body 15a. The magnet 11 is movable in expansion and contraction directions of the spring 3. The rectifier circuit 15 is fixed so that the magnetic body 15a is located outside a range where a movable range A of the magnet 11 is projected on the bottom surface.SELECTED DRAWING: Figure 4
