Abstract

PURPOSE: To improve a low frequency sound reproducing capability by inclining a magnet so as to be thinned as it is for separated from a magnetic gap.
CONSTITUTION: A magnetic circuit 13 is constituted by connecting a top plate 15 to a plate 17 having a pole piece 16 at both the sides of the magnet 14, and since the magnet 14 has an external periphery rise part upper corner inclined to the pole piece 16 side, the thickness is gradually thinned from an internal periphery to an external periphery. further, the top plate 15 is also inclined along the inclined magnet 14. Accordingly, the collision dimension of the intermediate part of a diaphragm 20 and the top plate 15 is enlarged and the maximum sound pressure level of a low frequency sound area can be enhanced. Thereby, the low frequency sound area reproducing capability is improved.
