To solve the above-mentioned problems, the utility model provides a kind of loudspeaker enclosure comprising surrounds the upper of accommodating space
Lid and lower cover, and the fixed loudspeaker monomer being contained in the accommodating space；The upper cover includes surrounding the receiving sky
Between side wall, the accommodating space is separated into ante-chamber and the back cavity opposite with the ante-chamber by the loudspeaker monomer, described to raise
Sound device case further includes the plate in the back cavity；The limit being equipped with the plate is provided on the loudspeaker enclosure
Structure, the plate are inserted in the position limiting structure, and surround the filling sound absorber of a both ends open jointly with the side wall
The sound absorption cavity of material；The plate includes the stainless steel stent and screen cloth that fitting is integrated.
As an improvement the hem width of the stainless steel stent is 0.2mm to 0.4mm.
As an improvement the stainless steel stent and the screen cloth are bonded by Hot melt adhesive tape.
As an improvement the position limiting structure is the slot being set on the side wall.
As an improvement the quantity of the slot be two, the both ends of the plate be inserted in respectively one it is described insert
In slot.
As an improvement the side of the plate includes the first straight line extended along the direction parallel with upper cover, from the
The second straight line that one straight line extends towards the direction inclination far from the upper cover, and from second straight line along the direction parallel with upper cover
The third straight line of extension.
As an improvement the screen cloth includes following any: non-woven fabrics, dust-proof screen cloth and Metal screen cloth.
As an improvement the slot includes the slot bottom extended to form from the side wall and extends shape from the slot bottom
At first cell wall parallel with corresponding side wall.
As an improvement the slot includes the second cell wall extended to form from the side wall and prolongs from the side wall
Stretch the third cell wall with second walls parallel to be formed.
The beneficial effects of the utility model are: the loudspeaker enclosure of the utility model has inserting for stainless steel stent by setting
Plate reduces the thickness of plate, increases the sound-absorbing aisle spare of loudspeaker enclosure back cavity, improves loudspeaker enclosure performance.

[specific embodiment]
The utility model is described in further detail below by specific embodiment combination attached drawing 1 to Fig. 3, so as to energy
The advantages of enough more fully understanding the embodiment of the utility model and its various aspects.Below in an example, it provides in detail below
The purpose of embodiment is easy for becoming apparent from present disclosure thorough explanation, rather than to the limit of the utility model
System.Wherein the words of the indicating positions such as upper and lower, left and right be only for shown structure in respective figure for position.
Embodiment 1
As shown in Figure 1, loudspeaker enclosure 10 provided by the embodiment of the utility model includes 11 He of upper cover for surrounding accommodating space
Lower cover 14, and the fixed loudspeaker monomer 15 being contained in accommodating space.As shown in Fig. 2, upper cover 11 includes surrounding receiving sky
Between side wall 111, accommodating space is separated into ante-chamber and the back cavity opposite with ante-chamber by loudspeaker monomer 15, and loudspeaker enclosure 10 also wraps
Include the plate 13 being located in back cavity；The position limiting structure being equipped with plate 13 is provided on loudspeaker enclosure 10, plate 13 plugs
In position limiting structure, and with side wall 111 surround jointly a both ends open filling sound-absorbing material sound absorption cavity.As shown in figure 3, inserting
Plate 13 includes the stainless steel stent 131 and screen cloth 133 that fitting is integrated, and the hem width of stainless steel stent 131 is 0.2mm to 0.4mm.
Specifically, the hem width of stainless steel stent 131 can be 0.2mm, 0.4mm or 0.3mm.Include stainless steel material
The plate of bracket, compared with the existing technology in the plastic slab formed by Shooting Technique for, since stainless steel stent can be with
It is made thickness thinner, thus that plate can be reduced, effectively increases sound-absorbing aisle spare, promotes acoustical behavior.In addition, the program has
There is good production, be conducive to control cost and improve efficiency.
In the utility model embodiment, stainless steel stent 131 and screen cloth 133 are bonded by Hot melt adhesive tape 132.It bonded
Cheng Zhong, using heat pressing process, binding force is good between stainless steel stent and screen cloth, and the plate reliability of formation is higher.
As shown in Fig. 2, position limiting structure is the slot being set on side wall.The quantity of slot is two, respectively slot 112
With slot 113.The both ends of plate 13 are inserted in respectively in a slot.But in practical applications, the quantity of slot is not limited to
In this.First parallel with corresponding side wall that slot 112 includes the slot bottom extended to form from side wall and extends to form from slot bottom
Cell wall, another cell wall of a part of side wall as slot 112.Slot 113 include the second cell wall for being extended to form from side wall with
And it is being extended to form from side wall with the second walls parallel third cell wall, slot bottom of a part of side wall as slot 113.
In practical applications, the form of position limiting structure is also not limited to slot, for example, it is also possible to be the form of interpolation slit.
Purpose using position limiting structure is the position for limiting plate 13 in back cavity.
