Abstract

PURPOSE:To decrease the loss of the leak magnetic flux of the magnetic circuit by securing a parallel consitution for the magnetic circuit of a small-size speaker, and thus to realize the low power consumption and high sound pressure output. CONSTITUTION:A parallel magnetic circuit consists of pole 21 of magnetic material, ring-shaped yoke 22 of magnetic material, armature 22 functioning as a magnet and diaphragm 24 of magnetic material. And the coil is mounted to pole 21. Then the magnetic circuit of one side is used as the bias circuit of diaphragm, and the other magnetic circuit is used as the driving circuit of 24 each. Thus the loss of the leak magnetic fulx is reduced, realizing the low power consumption and high sound pressure output.
