Abstract
An electromechanical generator for converting mechanical vibrational energy into electrical energy. The electromechanical generator has a housing and an electrically conductive coil assembly movably mounted in the housing. The coil assembly has radially inner and outer sides, and upper and lower edges. A mount for the coil assembly extends inwardly of the radially inner side for mounting the coil assembly for linear vibrational motion along an axis. A first biasing device is mounted between the housing and the mount to bias the electrically conductive coil assembly in opposed directions along the axis towards a central coil position, a magnetic core assembly is movably mounted in the housing for linear vibrational motion along the axis, and a second biasing device is mounted between the housing and the magnetic core assembly to bias the magnetic core assembly in opposed directions along the axis towards a central magnet position.
