DETAILED DESCRIPTION
[0025] In order to make the technical problem, technical scheme and beneficial effect of the utility model to be solved more clearly, the following is combined with the drawing and example, and the utility model is further explained in detail.
[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification and claims of the present application are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device that includes a list of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed or can optionally include other steps or units inherent to such processes, methods, products or devices. The terms "provided" and the like should be broadly understood, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. The terms "up", "down", "left", "right", "front", "back", "bottom" and the like indicate the orientation or position based on the orientation or position shown in the drawings, and are only for the convenience of description, and cannot be understood as a limitation on the technical solution.
[0027] It should be noted that the acoustic structure design and assembly process of the conventional small sound box has many defects, which seriously restricts the product performance and production efficiency. In the prior art, in order to ensure the stability of the loudspeaker unit and the diaphragm in the sound wave transmission process, the following two installation methods are usually used: one is to use adhesive to seal and fix the edges of the loudspeaker unit and the diaphragm on the front shell structure, and the other is to lock along the circumferential direction of the loudspeaker unit and the diaphragm. Although this structure can suppress resonance to a certain extent, it has the problems of complex process and low reliability. The adhesive process is easily affected by environmental temperature and humidity, resulting in uneven curing, and the adhesive layer is prone to aging and cracking after long-term use. The screw locking method has low assembly efficiency and has the risk of stress concentration.
[0028] In terms of sound cavity sealing structure, the conventional scheme usually adopts a split shell design. In specific implementation, soft material (such as sponge, non-woven fabric, etc.) is first attached to the inner wall of the single-sided shell, and then the other side shell is assembled in position by buckle or screw. The setting of soft material can prevent the slot of the two side shells from producing vibration sound when the wind force generated by the bass is blown horizontally and bounced back, but the setting of soft material will cause the installation structure of the sound cavity to be complex.
[0029] Therefore, how to simplify the assembly process, reduce the production cost, effectively suppress the sound cavity resonance and maintain the long-term stable acoustic sealing performance is a problem that needs to be solved at present.
[0030] For example, Figures 1-6As shown, the embodiment provides a thin sound box with optimized sound cavity and quick assembly. After the first shell 10 and the second shell 20 are connected and fastened, the edges of the first annular edge 11 and the edges of the second annular edge 21 are reversely crossed and tightly held, so that the wind force generated by the bass cannot be blown horizontally, avoiding hard collision and solving the problem of the sealing of the sound cavity. The first abutting column 12 and the second abutting column 22 cooperate to clamp the loudspeaker unit 50 and the diaphragm unit 60, eliminating the traditional complex secondary processing technology, making the assembly process of the sound box more relaxed and efficient, and avoiding the generation of air leakage and resonance.
[0031] Specifically, the thin sound box with optimized sound cavity and quick assembly includes a first shell 10 and a second shell 20 that are detachably connected. The first shell 10 extends along a first direction to the second shell 20. The first shell 10 extends along the first direction to form a first annular edge 11. The second shell 20 extends along the opposite direction of the first direction to form a second annular edge 21. The edges of the first annular edge 11 and the edges of the second annular edge 21 are both in the shape of "S". The edges of the first annular edge 11 and the edges of the second annular edge 21 are reversely and mutually engaged. The first annular edge 11 and the second annular edge 21 are buckled to form a sound cavity. The first annular edge 11 has a first abutting column 12 formed therein. The second annular edge 21 has a second abutting column 22 formed therein. The first abutting column 12 and the second abutting column 22 cooperate to clamp a loudspeaker unit 50 or a diaphragm unit 60.
[0032] The diaphragm unit 60 and the loudspeaker unit 50 are installed in the same sound cavity, achieving a heavy bass effect and significantly improving the overall sound effect of the sound box.
[0033] It should be noted that one of the first abutting column 12 and the second abutting column 22 is an annular column that matches the peripheral shape of the loudspeaker unit 50 or the diaphragm unit 60, which can be sealed according to the shape of the loudspeaker unit 50 or the diaphragm unit 60.
[0034] In one embodiment, the first shell 10 is circumferentially provided with an annular step 13, and the top of the second shell 20 abuts against the annular step 13. The annular step 13 enables the first shell 10 and the second shell 20 to form a stable and tight connection.
[0035] In one embodiment, the first shell 10 and the second shell 20 are detachably connected through an assembly unit 30.
[0036] Specifically, the assembly unit 30 includes a first mounting column 31 arranged in the first shell 10 and a second mounting column 32 arranged in the second shell 20. The second mounting column 32 is arranged in an annular groove 311 of the first mounting column 31. The first mounting column 31 is provided with a through hole, and the second mounting column 32 is provided with a screw hole. After the screw passes through the through hole, it is connected with the screw hole.
[0037] The assembling process is as follows: in the assembling process, first, the second mounting column 32 of the second shell 20 is aligned and placed into the annular groove 311 of the first mounting column 31 of the first shell 10. Then, a screw is used to pass through the through hole of the first mounting column 31 and is screwed into the screw hole of the second mounting column 32. With the tightening of the screw, a firm and stable connection is formed between the first shell 10 and the second shell 20.
[0038] In an embodiment, the assembly unit 30 is arranged in the sound cavity, and the assembly unit 30 in the sound cavity is adjacent to the horn unit 50 or the diaphragm unit 60. By arranging the assembly unit 30, the horn unit 50 and the diaphragm unit 60 are further fastened, and the stability of the horn unit 50 and the diaphragm unit 60 in the sound wave transmission process is ensured.
[0039] In an embodiment, the sound cavity is further provided with a pressing ring 40 for pressing the diaphragm unit 60. The pressing ring 40 is recessed inward to form an annular pressing groove 41, which corresponds to the position of the second abutting column 22. The annular pressing groove 41 and the second abutting column 22 cooperate to press the diaphragm unit 60. Specifically, the second abutting column 22 is placed in the annular pressing groove 41, and the first abutting column 12 abuts the other side of the pressing ring 40, and the three cooperate to press the diaphragm unit 60, so that the edge of the diaphragm unit 60 is pressed into an "S" shape. After the first shell 10 and the second shell 20 are assembled, the first abutting column 12, the second abutting column 22 and the pressing ring 40 automatically press the diaphragm unit 60, ensuring that the diaphragm unit 60 will not loosen or deviate during the operation of the sound box, and solving the problem of air leakage caused by loosening of the diaphragm.
[0040] In an embodiment, the second abutting column 22 and the first abutting column 12 are both in the shape of a ring. The ring-shaped first abutting column 12 and the ring-shaped second abutting column 22 are more suitable for the shape of the diaphragm unit 60 and the horn unit 50, and can tightly wrap the edges of the horn unit 50 and the diaphragm unit 60, ensuring that they will not shift or loosen during subsequent assembly. During assembly, the horn unit 50 and the diaphragm unit 60 are first placed in the first abutting column 12 or the second abutting column 22 of one of the shells, and then the other shell is assembled to press the horn unit 50 and the diaphragm unit 60.
[0041] In an embodiment, the first shell 10, the first annular flange 11 and the first mounting column 31 are integrally injection molded. The second shell 20, the second annular flange 21 and the second mounting column 32 are integrally injection molded. Integrally injection molding can ensure the tight connection and accurate alignment between the components, not only improving the assembly efficiency of the sound box, but also reducing the failure rate caused by mismatching of the components.
[0042] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the utility model.
[0043] The utility model patent is exemplarily described above in combination with the drawings, and obviously the implementation of the utility model patent is not limited by the above-mentioned mode. As long as various improvements are made by adopting the method concept and technical scheme of the utility model patent, or the concept and technical scheme of the utility model patent is directly applied to other occasions without improvement, it is within the protection scope of the utility model.
