Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of self-locking card button sealing multimedia loudspeaker box, as shown in Figures 1 and 2, this audio amplifier comprises loud speaker 1 and self-locking clip fastening seal audio tank shell 2, and loud speaker 1 places in the cavity 21 of self-locking clip fastening seal audio tank shell and is fixed on the installing hole 22.
Extremely shown in Figure 7 in conjunction with Fig. 3, this self-locking clip fastening seal audio tank shell 2 comprises: back cover 23 and protecgulum 24, protecgulum 24 matches with back cover 23 and forms a cavity 21 for accommodating loud speaker, protecgulum is provided with for the installing hole 22 that loud speaker is installed, certainly, installing hole also can be opened on the back cover in other embodiments, back cover 23 madial wall peripheries a plurality of projections 231 that distribute, the protuberance 241 to the extension of back cover bottom direction that protecgulum 24 inboard peripheries distribute and equate with described projection 231 quantity, the anterior sidewall of protuberance 241 is provided with the shrinkage pool 2411 corresponding with described projection 231, when protecgulum 24 was sealed on the back cover 23, described projection 231 snapped in the corresponding described shrinkage pool 2411.Certainly, in other embodiments, the anterior sidewall of protuberance can be provided with the groove corresponding with described projection, namely can be made as blind hole.The effect of groove or shrinkage pool is to be complementary with projection, and projection is blocked, and prevents the relative motion on fore-and-aft direction of protecgulum and back cover.
Each projection 231 both sides of back cover are respectively equipped with locating piece 232 among the utility model embodiment, locating piece rear portion 2321 is fixed on the back cover madial wall, locating piece anterior 2322 and back cover madial wall form an opening towards the draw-in groove 233 of protecgulum, when protecgulum 24 was sealed on the back cover 23, the front portion of protecgulum protuberance 241 snapped in this draw-in groove 233.Bottom at draw-in groove can arrange fillet, and the radius of fillet can be arranged in 0.5～1.5cm scope.
During assembling, to back cover 23, this Y-direction can be considered as the fore-and-aft direction of audio amplifier to protecgulum 24 along Y-direction capping among Fig. 2.In order to be convenient to assembling, so that projection 231 can be finished snap action more easily with the shrinkage pool 2411 on the protuberance 241, described projection 231 is provided with one first inclined-plane 2311 towards a side of protecgulum 24.During the motion of protuberance 241 front end edge Y-directions, can continue to front slide, until whole projection 231 snaps in the shrinkage pool 2411 along the first inclined-plane 2311.
In order further to be convenient to install, described protuberance 241 front ends are provided with the second inclined-plane 2412 that is complementary with described the first inclined-plane 2311.In the process that protuberance 241 moves along Y-direction, the relative sliding on two inclined-planes so that protuberance 241 front ends are more prone to cross projection 231, realizes that projection 231 snaps in the shrinkage pool 2411.
Be appreciated that, although locating piece front portion 2322 has certain elasticity, but in the process that prevents the slip of protuberance 241 front end edge Y-directions, be stuck on the end of locating piece front portion 2322, among the utility model embodiment, described locating piece 232 is provided with one the 3rd inclined-plane 2323 at draw-in groove 233 aperture positions, so the 3rd inclined-plane 2323 is a spigot surface.In order further to increase guide effect, described protuberance 241 front ends are provided with the 4th inclined-plane 2413 that is complementary with described the 3rd inclined-plane 2323.The bevel angle that is understandable that the first inclined-plane, the second inclined-plane, the 3rd inclined-plane and the 4th inclined-plane can be set in 30 °～60 ° scopes.
In order to realize the perfect adaptation of whole casing of loudspeaker box, increase the robustness of shell, described back cover 23 is engaged with the end face that protecgulum 24 docks.Back cover 23 arranges occlusal crib 243 at the docking end face among the utility model embodiment, and protecgulum arranges snap protrusions 242 at the docking end face, and snap protrusions 242 cooperates with occlusal crib 243, realizes the engaged of protecgulum and back cover.Certainly in other embodiments, can snap protrusions be set at the docking end face of back cover, at the docking end face of protecgulum occlusal crib be set, realize the engaged of protecgulum and back cover.
Can be found out by such scheme, can make the assembling of audio amplifier simple and easy quick among the utility model embodiment, can strengthen again the air-tightness of voice box casing, can also make the buckle generation self-locking of voice box casing and do not get loose; Do not re-use the usual installation method of beating screw fastening, thereby removed the visible mounting screw of outward appearance hole, make internal structure compacter and firm, beautified product appearance.
Above a kind of self-locking clip fastening seal audio tank shell and the multimedia loudspeaker box that the utility model embodiment is provided is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
