Abstract:
1. A voltage generating device comprising, an ferrous core mounted on a non-ferrous support plate, said core having a vertical post and said vertical post having a horizontal upper surface, an electromagnetic winding wound around said vertical post, a compression spring mounted over said core, said spring having an upper end located in a spaced manner above said upper surface of said vertical post, a movable plate mounted in a horizontal manner on said upper end of said spring, a permanent magnet mounted at underside of said movable plate and located directly above said upper surface of said vertical post, said movable plate being operative in an up and down manner against the spring force of said spring to operate said permanent magnet in a reciprocating movement between an upper position wherein said permanent magnet is positioned spaced from said upper surface of said vertical post, and a lower position wherein said permanent magnet is in contact with said upper surface of said vertical post whereby a current is generated in said electromagnetic winding by said reciprocating movement of said magnet relative to said core.
