Increased frequency power generation using low-frequency ambient vibrations

摘要

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.

1. An electrical power generator, comprising:
a housing; an inertial mass mounted in said housing, said inertial mass being capable of at least limited movement within said housing in response to vibration of said housing; and a transducer mounted within said housing and being coupled to said inertial mass such that said transducer undergoes oscillatory motion in response to the movement of said inertial mass resulting from the vibration, wherein said transducer is an electromagnetic transducer comprising a solenoid coil encircling a magnetic core, said coil being fixed within said housing and said core being suspended within said housing such that said core can be magnetically coupled to said inertial mass for concomitant movement with said inertial mass in response to the vibration, and can be substantially magnetically decoupled from said inertial mass during at least a portion of the movement of said inertial mass wherein said decoupled core undergoes the oscillatory motion relative to said coil to thereby induce current in said coil.
