Abstract
An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising a housing, an electrically conductive coil assembly movably mounted in the housing, the coil assembly having radially inner and outer sides, and upper and lower edges, thereof, a mount for the coil assembly extending inwardly of the radially inner side for mounting the coil assembly for linear vibrational motion along an axis about, a first biasing device 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 movably mounted in the housing for linear vibrational motion along the axis, and a second biasing device 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, wherein the magnetic core assembly encloses the electrically conductive coil assembly on the radially outer side and on the upper and lower edges, and on a part of the radially inner side, the magnetic core assembly having a gap on a radiall…
