When the display screen 2 is in the first state, as shown in FIG. 1, the back of the display screen 2 is parallel to the surface of the sound box body 1, and the display screen 2 is stored in the groove on the surface of the sound box body 1. When the display screen 2 is in the second state, as shown in FIG. 2, the first electric rotating assembly 3 drives the display screen 2 to unfold, and the display screen 2 is automatically opened from the surface of the sound box body 1 for use by the user.

[0042] The second electric rotating assembly 4 can control the display screen 2 to switch between the third state and the fourth state. It should be noted that the display screen 2 can be set to different shapes according to actual production needs, such as a circle, a square, a rectangle, or other polygons. In this embodiment, the display screen 2 is set to a rectangle, including two sets of symmetrical long sides and two sets of symmetrical short sides. When the display screen 2 is in the third state, the display screen 2 is still in the unfolded state, and the display screen 2 is in a landscape state, in which the two sets of long sides of the display screen 2 are horizontal, and the two sets of short sides are vertical. Meanwhile, the display screen 2 can also be inclined at an appropriate angle to meet the viewing angle needs of the user. When the display screen 2 is in the fourth state, as shown in FIG. 3, the second electric rotating assembly 4 drives the display screen 2 to rotate by 90° to switch the display screen 2 from the landscape state to a portrait state for use by the user. In the portrait state, the two sets of short sides of the display screen 2 are horizontal, and the two sets of long sides are vertical. Meanwhile, the display screen 2 can also be inclined at an appropriate angle to meet the viewing angle needs of the user.

The guide rail 340 is slidably connected with a sliding piece 350 which can slide along the length direction of the guide rail 340. The lifting limiter 330 is connected with the sliding piece 350 to realize the sliding connection between the lifting limiter 330 and the guide rail 340, and ensure the stability of the sliding process of the lifting limiter 330. In the embodiment, the sliding piece 350 can be a sliding block which is suitable for the sliding of the guide rail 340 in the prior art to ensure the stability of the sliding process.

[0063] Further, the guide rail 340 is respectively provided with a limiting plate 360 at both ends for limiting the sliding of the sliding piece 350. It should be noted that in the embodiment, the guide rail 340 is respectively provided with the limiting plate 360 at both ends to effectively limit the movement of the lifting limiter 330, thereby controlling the lifting range of the display screen 2 and avoiding the falling or impact between the lifting limiter 330 and the screw rod 320 to ensure the stability of the structure.

[0064] Further, referring to FIG. 17, in the embodiment, the lifting assembly 3 is further provided with a shell 380. At this time, the lifting assembly 3 is an independent and detachable whole and is accommodated in the shell 380 to meet the requirements of various application scenarios. For example, when not in use, the lifting assembly 3 can be accommodated in the sound box body 1 or can be separately accommodated in other areas as an independent component. When in use, referring to FIGS. 18 and 19, the lifting assembly 3 can be inserted into the first insertion opening 13 of the sound box body 1. The first insertion opening 13 can be provided with a plug-in terminal which is electrically connected with the lifting driving motor 310 of the lifting assembly 3 to realize the plug-and-play of the lifting assembly 3.
