Abstract

PURPOSE:To keep constant the differentiation permeability and to improve the nonlinearity of permeability of a magnetic circuit, by providing an amorphous magnetic substance body to a part facing the gap between a center pole and a plate forming a magnetic gap. CONSTITUTION:A magnetic gap 5 is formed with a center pole 2 at the center of a yoke 1 and a ring shape magnet 3 and a plate 4 on the above, and a voice coil 6 is placed, which is driven with a signal current to this part, and rings of magnetic substance bodies 8, 9 made of amorphous are provided at the part facing the magnetic gap 5 of this magnetic circuit member. Thus, the nonlinearity of the permeability of the magnetic circuit due to the AC magnetic flux produced with a signal current flowing to a voice coil can be improved and the harmonics of the signal current can be reduced, allowing to reduce the acoustic reproducing distortion.
