This paper proposes an electromagnetic induction type vibration generator using permanent magnets and coils. This proposal aims to improve the electromotive force by continuously moving the magnets and coils in opposite directions to increase the time rate of change of the magnetic field. To realize this continuous and opposite movement, a configuration using a “scissors type link mechanism” was examined. Furthermore, magnetic circuits, consisting of a magnetic flux around each cell of coils, were also used in conjunction to improve the electromotive force. A prototype implementing both of these characteristics was created to verify the actual effect of this configuration on its electromotive force and the generated magnetic attraction.
