Abstract:
A headphone includes an electro-acoustic transducer for creating audio output, the electro-acoustic transducer comprising a transducer magnet that produces a transducer magnetic field having a magnetic field strength, structure that is constructed and arranged to be positioned so as to direct the audio output at the ear canal of the ear of a wearer of the headphone, a magnetic field sensor constructed and arranged to sense the Earth's magnetic field, and a nulling magnet constructed and arranged to produce a nulling magnetic field that reduces the strength of the transducer magnetic field at the magnetic field sensor.

Claim (Index 9):
The audio device of  claim 1 , wherein the magnetic field sensor has a sensed magnetic field range where it operates linearly, and wherein the nulling magnetic field reduces the strength of the transducer magnetic field at the magnetic field sensor such that the sensed magnetic field strength is in the sensed magnetic field range where the magnetic field sensor operates linearly.
