Further, the raised height is less than the thickness of the center washer.
Further, it is described raised identical with shape, the length and width difference of the opening.
Further, in addition to glue-line, the center washer is arranged on the magnet steel by the glue-line.
Further, the described raised and magnet steel is integrally formed setting.
The beneficial effects of the utility model are：Center washer is provided with opening, and magnet steel is stretched into out provided with projection, projection
It is intraoral, the height sum of washer and magnet steel and the height sum identical feelings of center washer of the prior art and magnet steel at center
Under condition, the height of magnet steel can be increased, so as to strengthen magnetic field intensity, and then the sensitivity of loudspeaker can be improved；The projection of magnet steel
Coordinate with the opening of center washer, the center washer obscission caused by lateral external forces can be avoided, the reliable of product is improved
Property.

Embodiment
To describe technology contents of the present utility model, the objects and the effects in detail, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained in detail.
The design of the utility model most critical is：Magnet steel is provided with opening, passes through projection provided with projection, center washer
With the cooperation of opening, it can not only strengthen magnetic field, and can prevent center washer from coming off.
Refer to Fig. 1 to Fig. 3, a kind of magnetic circuit component of loudspeaker, including center washer 1 and magnet steel 2, the center washer
1 is arranged on the magnet steel 2, and the magnet steel 2 is provided with opening 11, described raised 21 provided with projection 21, the center washer 1
Stretch into the opening 11.
It was found from foregoing description, the beneficial effects of the utility model are：Center washer is provided with opening, and magnet steel is provided with
Projection, projection is stretched into opening, the height sum of washer and magnet steel and center washer of the prior art and magnet steel at center
In the case of height sum identical, the height of magnet steel can be increased, so as to strengthen magnetic field intensity, and then the spirit of loudspeaker can be improved
Sensitivity；The projection of magnet steel coordinates with the opening of center washer, can avoid the center washer obscission caused by lateral external forces, carry
The high reliability of product.
Further, described raised 21 be rectangle, and the center washer 1 is straight-flanked ring.
Further, raised 21 height is identical with the thickness of the center washer 1.
Further, raised 21 height is less than the thickness of the center washer 1.
Seen from the above description, during actual design, proportioning can be surveyed by product or convex by emulating proportioning regulation magnet steel
The height risen and the thickness relationship of center washer, it is raised away from magnet steel when raised height is identical with the thickness of center washer
With center washer away from magnet steel while flush, it is raised remote when raised height is less than the thickness of center washer
Magnet steel less than center washer away from magnet steel while.
Further, described raised 21 is identical with shape, the length and width difference of the opening 11.
Seen from the above description, it is raised identical with shape, the length and width of opening, make raised and opening formation gapless
Assembling, to ensure the tonequality of loudspeaker.
Further, in addition to glue-line, the center washer 1 is arranged on the magnet steel 2 by the glue-line.
Seen from the above description, center washer is connected by glue-line with magnet steel, and by the raised cooperation with opening, can be carried
The bonding strength of high center washer and magnet steel.
Further, described raised 21 it is integrally formed setting with the magnet steel 2.
Fig. 1 be refer to Fig. 3, embodiment one of the present utility model is：
A kind of magnetic circuit component of loudspeaker, including center washer 1 and magnet steel 2, the center washer 1 are arranged on by glue-line
On the magnet steel 2, the magnet steel 2 is provided with projection 21, and projection is 21 identical with the material of magnet steel 2, and magnet steel 2 is grown and is wider than convex
Rise 21 length and width, and projection 21 with magnet steel 2 be integrally formed setting.The center washer 1 is provided with opening 11, described raised 21
