Abstract

PURPOSE:To obtain a magnetic circuit of high magnetic flux density, by locating the magnetic substance in the space opposing the magnetic poles having concaved ends and locating the moving coil in the space between the magnetic poles and the magnetic substance. CONSTITUTION:The magnetic circuit is constituted with the magnet 11, magnet poles 12, 12' having concaved edge, and magnetic substance 19. The moving coil 13 is located in the space formed between the magnet poles 12, 12' and the magnetic substance 19. In the magnetic circuit of this constitution, since high magnetic flux density can be obtained to the magnetic gap G, the linearity can be improved and the magnetic circuit can be constituted simply.
