Abstract:
Magnetic field cancelling audio speakers and associated devices are disclosed. In one embodiment, a utility locator includes an audio speaker device with two loudspeaker drivers positioned and electrically connected to reduce emitted magnetic fields over a range of frequencies corresponding with locator sensing frequencies.

Claim (Index 22):
A magnetic field attenuating audio speaker device, comprising:\n a speaker enclosure; a first electrostatic loudspeaker driver having terminals operatively coupled to the input wiring to receive the audio output signal with a first polarity; and a second electrostatic loudspeaker driver, of the same type as the first loudspeaker driver, having terminals operatively coupled to the input wiring to receive the audio output signal with a second polarity; wherein the first loudspeaker driver and the second loudspeaker driver are positioned within the speaker enclosure so as to at least partially cancel alternating current (AC) magnetic field signals emitted therefrom over a predefined frequency or range of frequencies overlapping the frequency or range of frequencies emitted from the hidden or buried conductor.
