Abstract
An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising: a central mast, an electrically conductive coil assembly fixedly mounted to the mast, the coil assembly at least partly surrounding the mast, a mount for the coil assembly extending radially inwardly of the coil assembly and fixing the coil assembly to the mast, wherein the mount comprises a conical wall extending between the coil assembly and the mast, a magnetic core assembly movably mounted to the mast for linear vibrational motion along an axis about an equilibrium position on the axis, the magnetic core assembly at least partly surrounding the coil assembly and the mast, and a biasing device mounted between the mast and the magnetic core assembly to bias the magnetic core assembly in opposed directions along the axis towards the equilibrium position.
