[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] It should also be noted that the directional terms such as left, right, up and down in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0030] Please refer to Figure 1-4The spliced ​​sound bar disclosed in the present application includes a first box body 10 and a second box body 20. The first box body 10 is provided with a first connecting member 11, and the second box body 20 is provided with a second connecting member 21 matched with the first connecting member 11. The first box body 10 and the second box body 20 are detachably connected through the first connecting member 11 and the second connecting member 21; wherein the first connecting member 11 is a card slot with a gourd-shaped cross section and a first end aperture R1 greater than a second end aperture R2, and the second connecting member 21 is a card head with a T-shaped cross section and a first end diameter D1 greater than a second end diameter D2; the first end aperture R1 of the first connecting member 11 is greater than the first end diameter D1 of the second connecting member 21, and the second end aperture R2 of the first connecting member 11 is smaller than the first end diameter D1 of the second connecting member 21, so that the second connecting member 21 can be easily connected to the first connecting member 11 without causing the connection part between the two to loosen during use. Specifically, the first end aperture R1 of the first connecting member 11 is larger than the first end diameter D1 of the second connecting member 21, which can ensure that the second connecting member 21 can be easily inserted into the first end of the first connecting member 11, and the second end aperture R2 of the first connecting member 11 is smaller than the first end diameter D1 of the second connecting member 21, which can prevent the second connecting member 21 from escaping from the second end of the first connecting member 11, thereby ensuring that the first box body 10 and the second box body 20 are firmly and firmly connected.

[0031] Furthermore, the second end aperture R2 of the first connecting member 10 is slightly smaller than the second end diameter D2 of the second connecting member 21, so that when the second connecting member 21 is clamped in the first connecting member 11, the outer wall of the second end of the second connecting member 21 abuts against the inner wall of the second end of the first connecting member 11, thereby clamping the second connecting member in the first connecting member.

[0032] In a preferred embodiment, the second connecting member 21 is made of metal, which improves the product's anti-collision and anti-shearing properties, making the sound bar more stable during operation and avoiding the problem of poor sound quality due to splicing vibration.

[0033] To facilitate installation and disassembly, in one embodiment, the first end of the first connecting member 11 is arc-shaped, and the first end of the second connecting member 21 is circular; and / or the second end of the first connecting member 11 is arc-shaped, and the second end of the second connecting member 21 is circular.

[0034] In another embodiment, if Figure 5 As shown, the first end of the second connecting member 21 includes a first sub-end and a second sub-end. The first sub-end is far away from the second end of the second connecting member 21, and the second sub-end is connected to the second end of the second connecting member 21. The diameter D11 of the first sub-end is smaller than the diameter D12 of the second sub-end, thereby ensuring that the second connecting member 21 can be more easily inserted into the first connecting member 11 and is not easy to fall off.

[0035] refer to Figure 6-7 , which is a schematic diagram of the cross-sectional matching state of the first connecting member 11 and the second connecting member 21 during the splicing process of the first box body 10 and the second box body 20, Figure 6 Insert the second connecting piece 21 of the second box body 20 into the first end of the first connecting piece 11 of the first box body 10, and then rotate the second box body 20 or the first box body 10 in the direction shown in the figure to complete the splicing of the first box body 10 and the second box body 20. Figure 7 As shown, when the first box body 10 and the second box body 20 are spliced ​​together, the first end of the second connecting member 21 of the second box body 20 is transferred to the second end of the first connecting member 11 of the first box body. At this time, since the aperture R2 of the second end of the first connecting member 11 is smaller than the diameter D1 of the first end of the second connecting member 21, the second connecting member 21 can be ensured to be firmly connected to the first connecting member 11.

[0036] It should be noted that in the embodiment of the present application, the card slot is arranged on the first box body 10 and the card head is arranged on the second box body 20 . Alternatively, the card head may be arranged on the first box body 10 and the card slot may be arranged on the second box body 20 .

[0037] refer to Figure 8 , which is a schematic diagram of the sound wave transmission state in an embodiment. Since the first box body 10 is provided with a first sound hole 13 and the second box body 20 is provided with a second sound hole 23, when the first box body 10 and the second box body 20 are spliced, the internal space of the first box body and the internal space of the second box body are connected through the first sound hole 13 and the second sound hole 23, thereby increasing the volume of the entire speaker cavity and increasing the bass effect of the speaker.

[0038] It should be noted that the first sound hole 13 and the second sound hole 23 shown in the figure are a hole set at the connecting end surface of the first box body 10 and the second box body 20. In other embodiments, the first sound hole 13 and the second sound hole 23 are multiple holes set at the connecting end surface of the first box body 10 and the second box body 20. The multiple holes can ensure that the sound cavities are connected to each other on the one hand, and on the other hand, it can avoid the problem that the connection surface structure is poorly stable due to the setting of a single hole, and the vibration causes noise when the speaker is used.

[0039] refer to Fig. 9, which shows an enlarged structural diagram of the audio connection terminal of the first box 10 and the second box 20 in one embodiment of the present application; the first box 10 is provided with a first audio transmission terminal 12, and the second box 20 is provided with a second audio transmission terminal 22. The first audio transmission terminal 12 and the second audio transmission terminal are gold finger PCB boards. When the first box 10 and the second box 20 are spliced, the first audio transmission terminal 12 and the second audio transmission terminal 22 are connected for audio transmission. Using the gold finger PCB board in this embodiment as the audio transmission terminal can avoid adding an additional audio transmission line for audio transmission when multiple boxes are spliced, which improves the consistency of the product structure and also improves the user product experience.

[0040] Furthermore, in other embodiments, Fig.10 As shown, the spliced ​​sound bar 100 includes a first box 10, a second box 20, and a third box 30. The second box 20 is detachably connected to the first box 10 and the third box 30, respectively. A first silicone sealing ring 41 is provided between the first box 10 and the second box 20, and a second silicone sealing ring 42 is provided between the second box 20 and the third box 30. Of course, more boxes can be provided in other embodiments, so as to achieve the technical effect of high-quality speakers that are convenient to transport.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
