Abstract
An electromechanical generator comprising an electromechanical device for converting mechanical vibrational energy into electrical energy, the electromechanical device 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, 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.
