Topic.
The technical solution of the utility model is as follows: a kind of loudspeaker, comprising: shell open at one end is covered in shell
Cover board in opening, the cover board and the shell form cavity, and the loudspeaker monomer being mounted in the cavity；It is described
Loudspeaker monomer includes the magnetic bowl close to the cover board；The cover board is equipped with through-hole, institute at position corresponding with the magnetic bowl
It states magnetic bowl and is assemblied in the through-hole,
The cover board include cover board body and from cover board body towards the geometric center of the through-hole extend baffle；
The cover board body includes the first side wall and opposite with the first side wall position second close to the cavity
Side wall, the baffle include the lower bottom wall parallel with the first side wall, extend from the second sidewall and to first side
The inner wall of the inclined upper skew wall in wall direction and the connection lower bottom wall and the upper skew wall；
The magnetic bowl has stage portion corresponding with the baffle close to the side of the cover board, and the stage portion includes
The First terrace opposite with the inner wall of the baffle and the second step face to fit with the lower bottom wall of the baffle, institute
Stating has gap between baffle inner wall and the First terrace, to be sealed to the cover board and the magnetic bowl.
Further, skew wall, the baffle inner wall, the First terrace and the second step face are total on the baffle
With the groove surrounded for filling adhesive.
Further, the lower bottom wall is provided with the concave step being recessed to the upper skew wall, and the concave step includes
Connect the connection wall of the lower bottom wall and the first side wall；There is gap between the connection wall and the stage portion.
The utility model has the beneficial effects that: the utility model by allow baffle lower bottom wall and magnetic bowl stage portion the
Two step surfaces fit together, to eliminate fit-up gap between the two, when the exposed assembly of magnetic bowl, glue instils in institute
Skew wall on baffle, the baffle inner wall, the First terrace and the second step face is stated to be surrounded jointly for filling gluing
When the groove of agent, glue can be avoided to flow into inside acoustical generator from fit-up gap well and then lead to gas leakage or pollution loudspeaking
The generation of device monomer phenomenon effectively increases the yields of loudspeaker production.

[specific embodiment]
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
As Figure 1-Figure 5, a kind of loudspeaker provided in this embodiment, comprising: shell open at one end is covered in shell
Opening on cover board 1, the cover board 1 forms cavity, and the loudspeaker monomer being mounted in the cavity with the shell
2；The loudspeaker monomer 2 includes the magnetic bowl 21 close to the cover board 1；The cover board 1 is in position corresponding with the magnetic bowl 21
Place is equipped with through-hole 1a, and the magnetic bowl 21 is assemblied in the through-hole 1a；
The baffle that the cover board 1 extends including cover board body 11 and from cover board body 11 towards the geometric center of the through-hole 1a
12；
The cover board body 11 include close to the cavity the first side wall 11a and with the position the first side wall 11a phase
Pair second sidewall 11b, the baffle 12 includes the lower bottom wall 12a parallel with the first side wall 11a, from the second sidewall
11b extend and to the inclined upper skew wall 12b in the direction the first side wall 11a and connection lower bottom wall 12a and it is described it is upper tiltedly
The inner wall 12c of wall 12b；
The magnetic bowl 21 close to the side of the cover board 1 have stage portion 211 corresponding with the baffle 12, described
Rank portion 211 includes the First terrace 211a opposite with the inner wall 12c of the baffle 1 and the lower bottom wall with the baffle 1
There is gap between the second step face 211b that 12a fits, the baffle inner wall 12c and the First terrace 211a, with
The cover board 1 and the magnetic bowl 21 are sealed.
As shown in Figures 2 and 3, skew wall 12b on the baffle, the baffle inner wall 12c, the First terrace 211a and
