Abstract (en)
[origin: US6944306B1] A method of reproducing audio sound using low level electromagnetism applied to ambient air particles to create a new magnetic field. The method uses a device having at least one winding of electric wires that re wound onto a flexible polymer support. The impedance of the winding is 8 Ohms. The device is connected to an electric audio signal of an acoustic chamber or an acoustic supply. The device and method are useable with audio and audio-video systems, as well as other known methods of communication.
