ABSTRACT:
A hearing system for producing audio signals perceptible to an individual. The hearing system includes a transducer having a surface adapted to attach to a middle-ear acoustic member of the individual, wherein the transducer is responsive to variations in a magnetic field emitted by a transmitter to directly vibrate the acoustic member. The transmitter is supported within an ear canal of the individual. The transmitter has a coil and a core positioned so that the distal end of the core is located at a predetermined distance and orientation relative to the transducer.
