The electromechanical generator comprising a housing 4, an electrically conductive coil assembly 22 (40,42) fixedly mounted in the housing, the coil assembly having radially inner and outer sides, and upper and lower edges, thereof, a mount 24 for the coil assembly extending inwardly of the radially inner side for fixing the coil assembly in a fixed position in the housing, a magnetic core assembly 50 movably mounted in the housing for linear vibrational motion along an axis A-A, and biasing devices 82,84 mounted between the housing and the magnetic core assembly to bias the magnetic core assembly in opposed directions along the axis towards a central 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 radially inner portion thereof through which the mount extends, and the radially inner portion including two opposed magnets 53,54 spaced along the axis. The biasing deice may comprise spiral arms 108 extending between radial inner 90,92 and radial outer 82,84 mountings which are threaded 94,96,102,104 to the core and central tube 28 at opposing ends of the tube. Alternatively the bias means may comprise a stepped yoke configuration of springs (fig 3). The interior 16 of the housing may be gas filled and may be hermetically sealed. |
