Abstract
The Acoustic Magnetic Field Power Generator uses an acoustic signal focused into a permanent magnet to stimulate the nuclear structure of the magnet to cause the magnetic field of the permanent magnet to move or oscillate. This effect can be used to tap power from the oscillating magnetic field by putting a coil of wire in the oscillating field. When an alternating current signal generator is connected simultaneously to an acoustic transducer and a stimulating coil; whereby, both the acoustic transducer and the stimulating coil are located within the magnetic field of the magnet, the acoustic signal enhances the stimulating effect to the permanent magnet transformer. The acoustic transducer can be any acoustic generation device such as a piezoelectric, magnetostictive, or other acoustic transducer. The combined effect of the acoustic signal and the stimulating coil increases the efficiency of permanent magnet induction transformers.
