Abstract
An increased frequency power generator that includes a pair of transducers located on opposite sides of a suspended inertial mass. Magnetic attraction is used to couple the mass to each of the two transducers in alternating fashion in response to vibration and other movement externally imparted on the generator. Each transducer includes a suspended magnetic element that couples and decouples to the inertial mass as it reciprocates in the housing due to the applied external moving force. As the inertial mass decouples from one transducer on its way to magnetically connecting to the other transducer, the decoupled suspended magnetic element oscillates at a frequency greater than the imparting force, thereby generating electrical power.
