Abstract

PURPOSE:To forcibly lead magnetic flux to a magnetic gap and to reduce a leakage magnetic flux, by providing a center pole formed by a directional silicon steel plate. CONSTITUTION:A magnetic gap 13 is formed by placing a top plate 12 so that it holds a suitable gap to an opposed surface 11a of the magnetic gap at one end part of a center pole 11. This magnetic gap 13 is formed on both sides of the center pole 11, and diaphragm 14 of a ribbon foil are mounted to each magnetic gap 13. A top plate 12 is lapped on a magnet 15, and the magnet 15 is sandwiched between a back plate 16 connected to the other end part of the center pole 11 and the top plate 12. Furthermore, the center pole 11 is formed by a directional silicon steel plate.
