Electromechanical Generator for Converting Mechanical Vibrational Energy Into Electrical Energy
First Claim
1. An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator including a cantilever spring having a fixed end, a free end and a central portion therebetween, a mount for the cantilever spring to which the fixed end is fixed, a mass located at the free end of the cantilever spring, the mass including either a coil or at least one magnet defining a region of magnetic flux, wherein at least one of the fixed end and the free end of the cantilever spring is substantially stiffer than the central portion of the cantilever spring.

- 18. An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator including a cantilever spring having a fixed end and a free end, a mount for the cantilever spring to which the fixed end is fixed, a mass located at the free end of the cantilever spring, the mass including either a coil or at least one magnet defining a region of magnetic flux, the mass further including a support member integral with or connected to the cantilever spring, a holder for holding either the coil or the at least one magnet, and a screw threaded connector which fixes the holder to the support member, the screw threaded connector being adjustable thereby to vary the longitudinal position of the holder relative to the cantilever spring and thereby vary the resonant frequency of the electromechanical generator.
