ABSTRACT:
An electromagnetic driver transducer free of torque in the presence of an external magnetic field, of any direction and orientation (such as in a Magnetic Resonance Imaging environment). The transducer includes a housing. At least one coil is associated with the housing. A plurality of magnets within the housing are aligned along an axis in an anti-parallel orientation. The magnets are free to move along an axis, wherein vibration of the magnets causes vibration of the housing. The transducer may be, for example, fixed to an ossicle.
