Therefore, it is necessary to provide a kind of new loudspeaker enclosure.
【Utility model content】
To solve the above-mentioned problems, the utility model provides a kind of loudspeaker enclosure comprising the shell with receiving space
Body, with the cover board that the shell is combined and the loudspeaker monomer being contained in the receiving space, the shell and the cover board
It include groove on the face of weld being combined；The cover board includes welding bar corresponding with the position of the groove；The weldering
The profile of the outer profile and the groove that connect muscle matches.
As an improvement the shell includes side wall, the bottom wall being connected with the side wall and opposite with the bottom wall opens
Mouth end.
As an improvement the side wall includes along the side wall inner circumferential towards the receipts in the intersection with the bottom wall
Hold the stage portion of the inside protrusion in space, the stage portion is equipped with the groove combined with the welding bar.
As an improvement the groove is from the upper table of stage portion surface indentation downwards.
As an improvement the profile of the groove and the profile of the stage portion are corresponding.
As an improvement the depth of the groove is less than or equal to the structure height of the welding bar.
As an improvement the cross sectional shape of the groove is rectangle or upside-down trapezoid.
The utility model has the beneficial effects that：The loudspeaker enclosure of the utility model can effectively increase the weldering of shell and cover board
Connect contact area, improve the binding force after ultrasonic bonding, which thereby enhance the structural stability of loudspeaker enclosure, reliability and
Leakproofness also reduces the fraction defective of product.

Using the left and right directions of attached drawing paper as transverse direction or horizontal direction, and with the upper and lower directions of attached drawing paper be it is longitudinal or
Person's vertical direction.
Embodiment 1
As shown in Figure 1 to Figure 3, the utility model provides a kind of loudspeaker enclosure, which includes having receiving space
10 shell 1, with the cover board 2 that the shell 1 is combined and the loudspeaker monomer 3 being contained in the receiving space 10, wherein raise
Receiving space 10 is separated into ante-chamber and back cavity by sound device monomer 3；Shell 1 and cover board 2 are combined by way of ultrasonic bonding；Shell
Body 1 on the face of weld of cover board 2 include groove 14, cover board 2 includes welding bar corresponding with the position of the groove 4
21。
Specifically, shell 1 includes side wall 11, the bottom wall 12 being connected with the side wall 11 and the opening opposite with the bottom wall 12
End, wherein the side wall 11 and bottom wall 12 surround receiving space 10, and cover board 2 covers the open end for being connected to shell 1, side wall 11 with bottom
The intersection of wall 12 includes the stage portion 13 of the inside protrusion towards receiving space 10 along side wall inner circumferential, the stage portion 13 and side wall
11 shape is corresponding, and stage portion 13 is equipped with from the downward surface indentation in its upper surface and corresponding with the position of welding bar 21
Groove 14.
In order to increase welding contact area, groove 14 is additionally arranged in the stage portion 13 of the side wall 11 of shell 1.In this implementation
In mode, stage portion 13 and groove 14 are polyline shaped ring corresponding with the shape of side wall 11, as shown in Figure 1 and Figure 4, groove
