Therefore, by utilizing the sliding insertion relationship between the power guide 34 and the rotary sleeve 32 and the threaded sleeve-connection relationship between the power guide 34 and the linkage worm 33, in the process that the rotary power output by the motor driver 31 drives the linkage worm 33 to synchronously rotate, the power guide 34 can only move linearly along the axial direction of the rotary sleeve 32 (for example, perform linear lifting motion along the vertical direction), so that the man-machine interaction display mechanism 20 is pushed out of the storage cavity groove a or pulled to retract into the storage cavity groove a. Based on this, the accommodating cavity a arranged in the sound box body 10 can provide structural space for assembling and accommodating the human-computer interaction display mechanism 20 and the electric linear push-pull mechanism 30 at the same time, and the human-computer interaction display mechanism 20 can be retracted and accommodated in the sound box body 10 by utilizing the driving effect of the electric linear push-pull mechanism 30 on the human-computer interaction display mechanism 20, so that the hidden protection on the human-computer interaction display mechanism 20 is realized, and the effects of reducing the structural volume of the whole sound box when the sound box is idle and enhancing the portability of the sound box are achieved; moreover, the human-computer interaction display mechanism 20 can be pushed out from the sound box body 10 when the sound box is used, so that functions such as video playing, image displaying and the like can be conveniently carried out.

For optimizing the structure of the whole sound box, the motor driver 31 of this embodiment can adopt different structural styles and assembly modes according to actual conditions, specifically:

1. the motor driver 31 can be mainly composed of a power motor 31-1 which is arranged on the slot surface side of the containing cavity slot a and is coaxially distributed with the linkage worm 33, wherein the head end of the linkage worm 33 is connected with the output shaft of the power motor 31; therefore, the power motor 31-1 can be utilized to directly drive the linkage worm 33 to synchronously rotate so as to finally realize the linear position moving effect (such as linear lifting motion) of the human-computer interaction display mechanism 20 relative to the sound box body 10.

2. In order to more reasonably utilize the structural space of the storage cavity groove a, enhance the structural compactness between the components of the electric linear push-pull mechanism 30, and create conditions for reducing the volume or size of the whole sound box, the motor driver 31 of the embodiment may also adopt the following structure, that is: the motor driver 31 comprises a gear transmission 31-2 arranged on the groove surface of the accommodating cavity a and a power motor 31-1, wherein the power motor 31-1 is arranged on the gear transmission 31-2, an output shaft of the power motor is connected with a power input end of the gear transmission 31-2, and the head end of the linkage worm 33 is connected with a power output end of the gear transmission 31-2.
