Abstract
A magnetic circuit system includes a T-shaped yoke, a magnet, and a top plate. The top plate has a center hole, an internal end around the center hole thereof, and two projecting elements provided separately on upper surface and lower surface of the internal end, which improves non-linear distortion of a transducer using the magnetic circuit system.
