However, the welding bar is a protrusion for above-mentioned this loudspeaker enclosure, it is more difficult to melt, expend ultrasound
Wave energy is larger, and easily causes to damage to components such as sounding monomer, FPC in loudspeaker enclosure.To raising in the related technology
There are welding energy energy consumptions for sound device case greatly, the deficiency of welding effect difference.
Therefore, it is really necessary to provide a kind of new loudspeaker enclosure solution above-mentioned technical problem.
[utility model content]
The purpose of this utility model is to provide a kind of welding energy less energy-consuming and the good loudspeaker enclosures of welding effect.
In order to achieve the above object, the utility model provides a kind of loudspeaker enclosure comprising upper cover and is covered on institute
It states upper cover and surrounds the lower cover of accommodating space jointly with the upper cover, the junction of the upper cover and the lower cover is equipped with welding
Muscle, the welding bar are at least two protrusions arranged side by side.
Preferably, the protrusion is three.
Preferably, the section of the protrusion is trapezoidal or triangle.
Preferably, the upper cover includes upper cover plate and extends and abut from the periphery of the upper cover plate to the lower cover direction
In the side wall of the lower cover, the welding bar is set between the side wall and the lower cover.
Preferably, the side wall includes being recessed the container formed by it close to one end of the lower cover, the lower cover
Periphery is equipped with the faceplate that protrusion extends in the container, and the welding bar is set in the faceplate.
Preferably, the welding bar and the faceplate are in integral structure.
Preferably, welding bar structure annular in shape.
Compared with the relevant technologies, the upper cover that is set to of the loudspeaker enclosure of the utility model is connect with assembling for the lower cover
The welding bar at place is at least two protrusions arranged side by side, its welding surface width of welding bar composed by multiple protrusions can expire
The foot loudspeaker enclosure assembles fixed welding surface width requirement to the upper cover and the lower cover, but the single protrusion is compared
For a protrusion in the related technology, cross-sectional width is smaller, height it is lower, so as to for multiple spot simultaneously ultrasonic bonding,
The welding bar is easier to melt, and energy consumption is less, and weld strength is more preferable, and will not cause to damage to the component in the loudspeaker enclosure
Wound.
[Detailed description of the invention]
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the schematic perspective view of the utility model loudspeaker enclosure；
Fig. 2 is the optical cable of the utility model loudspeaker enclosure；
Fig. 3 is the lower cover structure schematic diagram of the utility model loudspeaker enclosure；
Fig. 4 is the cut-away view of the line A-A along Fig. 3；
Fig. 5 is enlarged schematic partial view shown in M in Fig. 4.
[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Refering to fig. 1-3, the utility model provides a kind of loudspeaker enclosure 100, including upper cover 1, lower cover 2, sounding monomer 3,
Welding bar 4 and FPC 5.
The upper cover 1 is oppositely arranged with the lower cover 2, the lower cover 2 lid set be fixed on the upper cover 1 and with the upper cover
1 surrounds accommodating space 10 jointly.The upper cover 1 and the lower cover 2 form sealing by ultrasonic bonding and fix.
The sounding monomer 3 is contained in the accommodating space 10, is used for sounding.
The upper cover 1 assembles junction equipped with welding bar 4, to realize institute by ultrasonic bonding with the lower cover 2
That states upper cover and the lower cover assembles fixation.In present embodiment, the welding bar 4 is at least two protrusions arranged side by side
41。
Specifically, can the covering according to required by raised 41 width and the welding bar 4 welding surface width
Rationally to determine raised 41 quantity.Preferably, raised 41 quantity is 3,3 raised 41 combined coverings
Welding surface width meets the loudspeaker enclosure 100 to the welding surface width requirement of the welding bar 4, thus single described raised 41
Width become smaller, correspondingly, single raised 41 height further decreases.To be easier to melt, the energy of welding disappears
Consumption is less, also avoids causing to damage to the component inside the loudspeaker enclosure, and weld strength is more preferable.
It is defined whether not identical to raised 41 cross sectional shape in present embodiment, but same cross-sectional shape
Raised 41 setting it is more easily molded.
Also raised 41 cross sectional shape is not limited specifically in present embodiment, but is with regular shape
Good, such as raised 41 section is trapezoidal or triangle, not only improves the molding of the welding bar, and provide stable weldering
Connect effect.
In present embodiment, the upper cover 1 includes upper cover plate 11 and from the periphery of the upper cover plate 11 to 2 side of lower cover
To the side wall 12 for extending and being connected to the lower cover 2, the welding bar 4 is set between the side wall 12 and the lower cover 2.By
This, welding effect is more preferable.
Specifically, the side wall 12 includes the container (not shown) formed that is recessed by it close to one end of the lower cover 2,
The periphery of the lower cover 2 is equipped with the faceplate 21 that protrusion extends in the container, and the welding bar 4 is set to the faceplate 21
On.To further improve welding effect.
More specifically, the welding bar 4 and the faceplate 21 are in integral structure.
In present embodiment, the welding bar 4 structure annular in shape.To further improve welding effect.
Compared with the relevant technologies, the upper cover that is set to of the loudspeaker enclosure of the utility model is connect with assembling for the lower cover
The welding bar at place is at least two protrusions arranged side by side, its welding surface width of welding bar composed by multiple protrusions can expire
The foot loudspeaker enclosure assembles fixed welding surface width requirement to the upper cover and the lower cover, but the single protrusion is compared
For a protrusion in the related technology, cross-sectional width is smaller, height it is lower, so as to for multiple spot simultaneously ultrasonic bonding,
The welding bar is easier to melt, and energy consumption is less, and weld strength is more preferable, and will not cause to damage to the component in the loudspeaker enclosure
Wound.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are also included in the patent protection scope of the utility model.
