Kind Code:
B2
Abstract:
An improvement in an electro-acoustic converter having a magnetic anisotropic circuit with air gap therein, the improvement including an air gap formed of a magnetic material laminated with an insulating layer having a comparatively higher magnetic resistance in the magnetic circuit, thereby increasing a magnetic resistance against a magnetic flux caused by a voice coil and acting so as to reduce eddy current losses, and thus eliminating the reproduction distortion caused by the magnetic non-linearity of the magnetic circuit.
