A rotating frame 17 is fixed on the outer surface of the worm 16. A cover plate 18 is fixed on the front end of the rotating frame 17. A protective frame 19 is fixed on the outer surface of the rotating rod 11. An audio group 3 20 is embedded in the inner wall of the protective frame 19. The protective frame 19 protects the audio group 3 20 inside it and wraps the audio group 2 10. The two vertical frames 2 shield and protect the audio group 1 9 in the lifting frame 8, so that multiple audio groups can be safely placed when stored or not in use, avoiding the influence of external collisions, water vapor and other factors, and also reducing the volume for convenient storage and transportation.

[0037] The bottom end of the rotating rod 11 on the left side passes through the inside of the chassis 1 and is fixed with a transmission gear 21. A gear ring 22 is rotatably connected to the upper surface of the inside of the chassis 1. Four through slots 24 and four through slots 1 23 are provided on the outer surface of the chassis 1. A rotating shaft 27 is rotatably connected to the inside of the through slot 1 23. A support leg 28 is fixed to the outer surface of the rotating shaft 27.

The four universal wheels 36 make it easy to move the whole speaker. When the spur gear 5 32 rotates, the screw rod 2 33 rotates accordingly, which will make the screw plate 34 and the lifting plate 35 drive the universal wheel 36 to rise vertically, so that the universal wheel 36 is stored inward, so that it is no longer in contact with the ground, so as to avoid the sliding of the roller of the universal wheel 36 when the speaker is used, making the speaker unstable;

[0039] When in use, the motor 6 is controlled to operate to rotate the screw rod 7, thereby moving the lifting frame 8 upward. During the lifting process of the lifting frame 8, the top pushes the cover plate 18 to flip it open with the rotating frame 17, driving the worm 16 to rotate, and in turn through the worm gear 15, the spur gear three 14, the spur gear two 13, and the spur gear one 12 on both sides to rotate the rotating rod 11 and drive the guard frame 19 to rotate and open outward, so that the sound group three 20 inside the guard frame 19 is exposed, the sound group one 9 at the lifting frame 8 after lifting is exposed, and the sound group two 10 no longer blocked by the two guard frames 19 is exposed. Fig. 9 As shown, all the sound groups face forward to form a sound matrix, which makes the sound playing effect better;

[0040] At the same time, when the left rotating rod 11 rotates, the gear ring 22 is rotated through the transmission gear 21 at the bottom thereof, and the gear ring 22 is used for transmission, and the spur gear 4 29 and the spur gear 5 32 are rotated at the same time. After the spur gear 5 32 rotates, the screw plate 34 and the lifting plate 35 drive the universal wheel 36 to rise through the screw rod 2 33, so that the universal wheel 36 is stored in the through groove 2 24. After the spur gear 4 29 rotates, the shaft 1 26, the bevel gear 1 30, and the bevel gear 2 31 are sequentially driven to rotate the shaft 2 27 and the leg 28. The outer end of the flipped leg 28 contacts the ground to support the chassis 1 and other structures, so that the device can be stably placed and used after being moved and when in use.

When the transmission gear 21 rotates, the gear ring 22 will be driven to rotate, and the rotating gear ring 22 will respectively drive the spur gears 5 32 and the spur gears 4 29.

[0042] Reference Figure 3-6 The lower surface of the cover 18 is respectively in contact with the upper surfaces of the two guard frames 19, the upper surfaces of the two vertical frames 2, and the upper surface of the lifting frame 8. The cover 18 blocks the top of the gap between the guard frames 19, the vertical frames 2, and the lifting frame 8 to prevent water stains from flowing down through the gap and invading the audio equipment inside the structure.

[0043] Reference Figure 3-6 The inner sides of the two guard frames 19 are in contact with the outer surfaces of the two vertical frames 2 and the outer surfaces of the lifting frame 8, so as to shield and protect the sound set 3 20 inside the guard frames 19.

[0044] Reference Figure 2-7 The leg 28 is a U-shaped structure, and the end of the leg 28 away from the chassis 1 is an arc-shaped structure. The arc end of the leg 28 contacts the ground after the leg 28 rotates, so that the device can be stably supported. The chassis 1 is a disc structure with an opening at the center of the lower surface and a hollow interior. The hollow interior is used for reasonable arrangement of other structures.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention.
