Abstract:
1. An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising an electrically conductive coil assembly having a longitudinally extending axis parallel to a central axis of the generator and a magnet assembly, each assembly being movably mounted for linear vibrational motion parallel to the central axis of the generator, and first and second biasing devices for respectively biasing the electrically conductive coil assembly and the magnet assembly in opposed directions parallel to the central axis towards a respective central position, wherein the magnet assembly comprises two magnetic circuits vertically spaced apart, a first magnetic assembly of the two magnetic circuits radially spaced inboard from an upper portion of the coil assembly and a second of the two magnetic circuits radially spaced inboard from a lower portion of the coil assembly, the magnetic flux of the magnetic circuits being in opposition.
