According to one embodiment of the present utility model, there is provided a kind of housing for loudspeaker.As shown in Figure 1-2, should
Housing includes protecgulum 11 and rear shell 15.Protecgulum 11 is fastened in rear shell 15, to form accommodating chamber between protecgulum 11 and rear shell 15.
Sheet metal is fixed with rear shell 15.Sheet metal protrude from rear shell 15 for the first surface 26 that is connected with protecgulum 11.Metal
Piece is arranged on the periphery of protecgulum 11.Sheet metal is as barrier wall structure.Gluing is formed between the side of sheet metal and protecgulum 11
Groove 25.
In the utility model embodiment, barrier wall structure is sheet metal.The structural strength of metal material is high, and sheet metal
Small more of thickness than being molded the barrier wall structure formed by high polymer material so that between the side of protecgulum 11 and sheet metal
Away from increase.The setting of sheet metal can increase the width of coating groove 25, so as to accommodate more binding agents.This cause protecgulum 11 with
Sealing effectiveness between rear shell 15 is more preferable, is effectively improved the waterproof effect of loudspeaker.
Alternatively, the material of sheet metal can be, but not limited to, stainless steel, carbon steel, copper alloy, aluminium alloy, galvanized sheet
Deng.Sheet metal can be loop configuration.The sheet metal of annular is centered around the outside of protecgulum 11.
Sheet metal can also be one section of sheet material.Sheet metal be arranged on rear shell 15 on a certain section of protecgulum 11, with increase
Add the local width of coating groove 25.
The shape of sheet metal does not limit herein, and those skilled in the art can be configured according to being actually needed.
Preferably, as shown in figs. 1 and 3, sheet metal is L-shaped.Sheet metal includes longitudinal edge 12 and horizontal edge 27.One end of longitudinal edge 12
It is connected with one end of horizontal edge 27.The horizontal edge 27 of sheet metal is embedded in the shell wall of rear shell 15.The outer surface of the longitudinal edge 12 of sheet metal
It is concordant with the outer surface of rear shell 15.Here, outer surface is the surface of the remote accommodating chamber of sheet metal and rear shell.Longitudinal edge 12
Part protrusion first surface 26.There are bigger contact area, and horizontal edge 27 and rear shell between the sheet metal and rear shell 15 of L-type
Interference is formed between 15 shell wall.This make it that the adhesion between sheet metal and rear shell 15 is stronger, and sheet metal is more firm, is not easy to send out
It is raw to tilt.
In addition, the outer surface of longitudinal edge 12 is concordant with the outer surface of rear shell 15, it is smaller that this make it that the volume energy of housing is done,
Profile is more regular, has complied with the development trend that electronic equipment is lightening, minimizes.
Preferably, sheet metal is fixed in rear shell 15 by insert injection moulding.Insert injection moulding causes sheet metal and rear shell 15
Bonding strength improve, and the connection of the two becomes easy.
For example, sheet metal is L-shaped steel disc 16.In injection, first, L-shaped steel disc 16 is placed into the setting position of mould；
Then, injection molding material is molded into mould.Rear shell 15 is formed after injection molding material solidification.The horizontal edge 27 of L-shaped steel disc 16 is embedded in rear shell
In 15 shell wall, to form the fixation to L-shaped steel disc 16.
In one example, rear shell 15 includes straight flange.Sheet metal is arranged on the straight flange of rear shell 15, sheet metal and straight flange
It is parallel.So, the simple shape of sheet metal, it is easy to process.

26.The corner of protecgulum 11 is provided with locating notch.In a pre-installation during lid 11, locating notch snaps into the outside of locating dowel, to enter
Row positioning.In this way, it can effectively prevent protecgulum 11 from glancing off, to improve the installation accuracy of protecgulum 11.
Further, at least two corners of rear shell 15 are provided with locating dowel 28.Multiple locating dowels 28 can be carried further
The installation accuracy of high protecgulum 11.
Preferably, locating dowel 28 and rear shell 15 are integrally formed.For example, integrally noted using thermoplastic elastomer (TPE) (TPU)
It is moulded into type.
Certainly, locating dowel 28 can be arranged on other positions by those skilled in the art according to being actually needed, as long as can be with
The breach of protecgulum, which is formed, to be coordinated, to be positioned.
Further, two locating dowels 28 are provided with first surface 26.The position of two locating dowels 28 and protecgulum 11
Relative two corner position it is corresponding.Locating dowel 28 limits position of the protecgulum along the direction parallel to first surface 26
Move, which further increases the positioning precision of protecgulum 11.
In one example, as shown in Fig. 2 the side of protecgulum 11 includes the backstop of the outwardly side wall 13 in protecgulum 11
Portion 14.Stopper section 14 is configured to form backstop with binding agent, to prevent protecgulum 11 away from first surface 26.Pass through backstop
The setting in portion 14, the side of protecgulum 11 form step-like structure.This causes binding agent and protecgulum 11 to have bigger contact area,
Make protecgulum 11 and the connection of rear shell 15 more firm, the waterproof effect of housing can be improved.
Preferably, the side of the close rear shell 15 of protecgulum 11 is provided with second surface.Second surface and first surface 26
Structure matches, to form sealing.
Alternatively, first surface 26 and second surface are plane, cambered surface or irregular surface, as long as the two can be pasted
Close, to form sealing.
