1. An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising:
- an electrically conductive coil assembly;
a magnet assembly, the magnet assembly including at least one magnet and a two-part magnetic core; and
a biasing device that mounts the two parts of the magnetic core so as to be relatively vibratable at a resonant frequency along an axis about a central position thereby to cause a change of magnetic flux linked with the conductive coil assembly to generate an electrical potential in the coil assembly;
wherein a second part of the magnetic core encloses the electrically conductive coil assembly, the at least one magnet, and a first part of the magnetic core.
