Abstract

PURPOSE:To reduce the distortion and to enable the reproduction of sound with fidelity, by using the magnetic substance forming the metal constitution in which the cementite having the saturation magnetization of mother phase encloses the iron of mother phase with scatter, for a part or all the magentic circuit. CONSTITUTION:In the magnetic circuit constituting with the upper plate 1, yoke 2, lower plate 3, permanent magnet 4, and pole 5, the magnetic substances 8, 9 excellent in the linearity of the magnetic characteristics are inserted to the part opposing to the upper plate 1 and the voice coil 6 of the pole 5. As the magnetic substances 8, 9, the substance formed with the metal constitution in which the cementite (Fe3C) having lower saturation of magnetization than that of the mother phase encloses the iron (Fe) of mother phase with scatter is used by machining and heat treatment suitable for soft steel such as low carbon steel.
