[0040] The specific operations are as follows:

[0041] During use, the speaker 2 is used to play sounds, and the protective box 1 protects the speaker 2. When the playing angle of the speaker 2 needs to be adjusted, it is only necessary to apply external force to the movable plate 303 to compress the telescopic column 304, thereby separating the limit rod 307 from the limit hole 306 to release the fixation, and then drive the speaker 2 to rotate through the connecting shaft 301 to adjust its angle. After the adjustment is completed, the external force is released, and the limit rod 307 can be reset by relying on the resilience of the telescopic column 304 and the spring 305, so that it is in the adjusted limit hole 306, and the adjusted angle can be fixed. This adjustment method can not only achieve adjustment and fixing, effectively improving its adjustment efficiency, but also the adjustment process is simple and easy to operate.

[0042] like Figure 3-4As shown, as an embodiment, a bearing seat 5 is fixed at the bottom end of the protective box 1, and a concave cavity is opened in the bearing seat 5; a moving component 4 is installed in the concave cavity, and the moving component 4 includes: a bidirectional screw 408; the bidirectional screw 408 is rotatably installed between the inner walls of the bearing seat 5; a knob 402, the knob 402 is fixedly connected to one end of the bidirectional screw 408 and the surface is frosted and anti-slip; a screw block 409, the screw block 409 has two groups and is symmetrically screwed on the bidirectional screw 408 through threads; a guide rod 406, the guide rod 406 is fixed in the bearing seat 5; a guide block 407, the guide block 407 has two The two-way screw 408 and the guide block 407 are respectively arranged directly below the lifting plate 403; the linkage rod 401 is rotatably installed between the screw block 409 and the lifting plate 403 and between the guide block 407 and the lifting plate 403, and the linkage rod 401 is cross-arranged and rotatably connected at the intersection; the universal wheel 405 is symmetrically fixed on both sides of the bottom end of the lifting plate 403.

[0043] The specific operations are as follows:

[0044] When the speaker 2 is in use, the support base 5 supports the speaker 2 to ensure its stability during use. When the speaker 2 needs to be moved, the knob 402 drives the bidirectional screw 408 to rotate, and then the screw block 409 moves under the action of the thread. The screw block 409 then drives the guide block 407 to slide on the guide rod 406 through the connecting rod 404. During the movement of the screw block 409 and the guide block 407, the linkage rod 401 rotates accordingly, thereby pushing the lifting plate 403 downward, so that the universal wheel 405 contacts the ground and supports the device, thereby facilitating the movement of the device.

[0045] like Figure 5 As shown, as an implementation mode: an operation box 6 is installed on the back wall of the protection box 1, and the operation box 6 is provided with a volume adjustment knob 402, a USB interface, etc.

[0047] The playing content can be imported into the audio system 2 through the operation box 6, and the playing volume of the audio system 2 can be adjusted at the same time.

[0048] In summary, the working principle of this easy-to-adjust audio device is as follows: first, the device is connected to an external power source, and then the playing content can be imported into the speaker 2 through the operation box 6, and then the playing volume of the speaker 2 is adjusted, and then the speaker 2 plays the imported content. During the playing process, the protective box 1 protects it, and the bearing seat 5 supports it to ensure its stability. When it is necessary to adjust the playing angle of the speaker 2, it is only necessary to apply external force to the movable plate 303 to compress the telescopic column 304, thereby separating the limit rod 307 from the limit hole 306 to release the fixation, and then drive the speaker 2 to rotate through the connecting shaft 301 to adjust its angle. After the adjustment is completed, the external force is released, and the telescopic column The rebound force of 304 and spring 305 can reset the limit rod 307 so that it is in the adjusted limit hole 306, so that the adjusted angle can be fixed. This method not only has high adjustment efficiency, but also is convenient for staff to operate. When the speaker 2 needs to change its usage position, the two-way screw rod 408 is driven to rotate by the knob 402, and then the screw block 409 moves under the action of the thread, and the screw block 409 drives the guide block 407 to slide on the guide rod 406 through the connecting rod 404. During the movement of the screw block 409 and the guide block 407, the linkage rod 401 rotates accordingly, thereby pushing the lifting plate 403 downward, so that the universal wheel 405 contacts the ground and supports the device, thereby facilitating the movement of the device.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
