Abstract:
1. An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising a housing, an electrically conductive coil fixedly mounted in the housing, a magnet assembly movably mounted in the housing for linear vibrational motion along an axis, the magnet assembly having a pair of opposed polar surfaces defining a gap therebetween, the coil being disposed in the gap, electrical circuitry for controlling the output of the electrically conductive coil, the electrical circuitry being electrically connected to the coil, an annular body of cast resin surrounding and encapsulating within the resin the electrically conductive coil and the electrical circuitry connected thereto, and a biasing device mounted between the housing and the magnet assembly, the biasing device biasing the magnet assembly in opposed directions along the axis towards a central position.
