ABSTRACT:
A signal isolation system includes an aeroisolator to couple output signals to an electronic device. The aeroisolator is made from two commercial miniature earphones, each having a ferro-magnetic diaphragm activated by a voice coil in proximity to a permanent magnet. The diaphragm is removed from one of the earphones, and the two earphones are then disposed in proximity to each other, with the diaphragm in proximity to the voice coil of each.
