Title:
VIBRATION POWER GENERATOR AND NONLINEAR VIBRATOR
Document Type and Number:
Japanese Patent JP2019134540
Kind Code:
A
Abstract:
To provide a small-sized vibration power generator and a nonlinear vibrator having high power generation capability.SOLUTION: A vibration power generator 1 includes: a nonlinear vibrator 50; a generator G that converts mechanical energy given from a vibration source 100 to the nonlinear vibrator 50 into electric energy; and an output circuit 18 that outputs the electric energy input from the generator G to the outside. The nonlinear vibrator 50 includes: a cylindrical body 56; a movable magnet 14 installed in the cylindrical body 56 so as to be movable in a cylindrical axis direction; fixed magnets 51, 52 arranged at positions outside a volume range in which the movable magnet 14 in the cylindrical body 56 moves. One magnetic pole in the cylinder axis direction of the movable magnet 14 is different from a magnetic pole on the movable magnet 14 side of the fixed magnets 51, 52 located on one side of the movable magnet 14, so that a magnetic spring is formed between the movable magnet 14 and the fixed magnets 51, 52.SELECTED DRAWING: Figure 3
