Among them, the display screen can rotate relative to the speaker main body back and forth and / or up and down through the folding mechanism. A storage bin adapted to accommodate the display screen is embedded in the back of the speaker main body. When the display screen rotates to the storage position, the display screen is correspondingly installed in the storage bin. The folding mechanism includes an upper fixing seat, a lower fixing seat, four rotating shaft screws and two oppositely arranged support rods. The two ends of the support rod are rotatably connected to the upper fixing seat and the lower fixing seat, and a damping component is arranged at the connection of the support rod and the upper fixing seat and the lower fixing seat.

[0007] In a preferred embodiment, the damping component includes a gasket, a spring piece and a spring stacked in sequence. A rotating shaft cover is sleeved outside the spring. The gasket, the spring piece, the spring and the rotating shaft cover are all provided with through holes opened transversely.

[0008] In a preferred embodiment, the gasket abuts against the side wall of the support rod. Installation holes corresponding to the through holes are respectively formed at both ends of the support rod, and the rotating shaft screw is installed in the installation hole and one end thereof penetrates out of the installation hole.

Both ends of the support rod 302 are rotatably connected to the upper fixing seat 301 and the lower fixing seat 303. Damping components are provided at the connection points of the support rod 302 with the upper fixing seat 301 and the lower fixing seat 303. A folding mechanism 3 with double support rods 302 is designed between the speaker main body 1 and the display screen 2. When the display screen 2 rotates, the rotating force can be evenly distributed to the support rods 302 on both sides, making the display screen 2 more stable during the rotation process. Secondly, the weight of the display screen 2 is borne by the two support rods 302, and the folding mechanism 3 is not easily damaged, which can ensure the service life of the folding mechanism 3.

[0030] Furthermore, the damping component includes a gasket 310, a shrapnel 309, and a spring 308 stacked in sequence. A rotating shaft cover 304 is sleeved outside the spring 308. The gasket 310, the shrapnel 309, the spring 308, and the rotating shaft cover 304 all have through holes opened transversely. The gasket 310 abuts against the side wall of the support rod 302. Installation holes corresponding to the through holes are respectively opened at both ends of the support rod 302. The rotating shaft screw 311 is installed in the installation hole and one end thereof passes out of the installation hole. A nut 305 coaxial with the through hole is provided on the outer wall of the rotating shaft cover 304. A threaded portion is provided at one end of the rotating shaft screw 311. The threaded portion of the rotating shaft screw 311 passes through the through hole and is threadedly connected to the nut 305. A damping part is designed between the speaker main body 1 and the display screen 2, which can realize the fixation of the position of the display screen 2 after adjusting the position of the display screen 2, with better use effects. A spring 308 is designed in the damping part, and the damping of the entire folding mechanism can also be correspondingly adjusted according to the use requirements. During adjustment, only the feeding depth of the nut 305 needs to be correspondingly adjusted, with better use effects and can also ensure the service life of the folding mechanism 3.

[0031] Further, it further includes a cable 4, and both ends of the cable 4 are electrically connected to the speaker main body 1 and the display screen 2 (with a main board), and the speaker main body 1, the display screen 2, the upper fixing seat 301, and the lower fixing seat 303 are respectively provided with wire passing holes 306 for the cable 4 to pass through.

[0032] Further, there are four elastic pieces 309, which are respectively arranged on both sides of the upper fixing seat 301 and the lower fixing seat 303, and the upper fixing seat 301 and the lower fixing seat 303 are respectively installed at the center of the back of the display screen 2 and the top of the back of the speaker main body 1.

[0033] Further, a handle position 501 is formed by the downward depression of the inner wall at the lower end of the storage bin 5. The storage bin 5 with the handle position 501 can be used to pull out the display screen from the storage bin 5 when using the display screen 2.

[0034] Further, mounting holes 307 are provided at the four corners and the middle of the upper fixing seat 301 and the lower fixing seat 303, and threaded holes 6 are respectively provided on the back of the speaker main body 1 and the display screen 2 corresponding to the mounting holes 307. The upper fixing seat 301 and the lower fixing seat 303 can be assembled with the display screen 2 and the speaker main body 1 respectively by screws (not shown in the figure).

[0035] Further, at least two limiting convex columns 101 are symmetrically provided at the top of the back of the speaker main body 1, and the lower fixing seat 303 is further provided with limiting holes adapted to the insertion of the limiting convex columns 101. Through the cooperation of the limiting convex columns 101 and the limiting holes, the installation position of the lower fixing seat 303 and the speaker main body 1 can be limited, and the installation accuracy is higher.

[0036] In summary, a folding mechanism 3 of a double support rod 302 is designed between the speaker main body 1 and the display screen 2. When the display screen 2 rotates, the rotating force can be evenly distributed to the support rods 302 on both sides, and the display screen 2 is more stable during the rotation process. Secondly, the weight of the display screen 2 is borne by the two support rods 302, and the folding mechanism 3 is not easily damaged; in addition, the folding mechanism 3 adopts an up-and-down four-rotating shaft structure, and the display screen 2 can rotate up and down and back and forth, so that the display screen 2 can be received in the storage bin 5 at a suitable angle, or the display screen 2 can be opened to a suitable angle for people to watch and operate, with better use effects. Moreover, it will not additionally increase the volume of the speaker box 1 after storage, which is convenient for users to carry, solves the problem of single product form, and increases diversity and market competitiveness.
