[0029] In addition, a lifting mechanism 9 is mounted at the bottom of the shell 8, and the user can adjust the height of the loudspeaker by adjusting the lifting mechanism 9, so as to optimize the use experience and make the loudspeaker better adapt to different use environments and personal preferences, thereby further improving the practicability and user satisfaction of the product. Specifically, the lifting mechanism 9 comprises two groups of oppositely arranged V-shaped lifting frames 91, one end of the two groups of V-shaped lifting frames 91 is hinged to a hinge seat 94, the hinge seat 94 is mounted on the lower end face of the shell 8 and is locked and fixed with the shell 8 by using screws, the other end is hinged to a base, and the two groups of V-shaped lifting frames 91 are movably connected with the corresponding parts by six rotating rods 93, so that the two groups of V-shaped lifting frames 91 can move synchronously. Two rotating rods 93 located in the middle of the V-shaped lifting frames 91 are provided with a lifting adjusting assembly 92 for adjusting the included angle of the V-shaped lifting frames 91. When the included angle of the V-shaped lifting frames 91 decreases, the V-shaped lifting frames 91 drive the loudspeaker to rise. When the included angle of the V-shaped lifting frames 91 disappears, the V-shaped lifting frames 91 drive the loudspeaker to descend.

[0030] The lifting adjusting assembly 92 comprises a stud 921 and a control handle for rotating the stud 921. One threaded segment of the stud 921 is screwed with a rotating rod 93 for connecting one group of V-shaped lifting frames 91, and the other threaded segment is screwed with a rotating rod 93 for connecting the other group of V-shaped lifting frames 91. The control handle is fixed at one end of the stud 921. For example, when the control handle is controlled in the forward direction, the control handle drives the stud 921 to rotate, the stud 921 pushes the two groups of V-shaped lifting frames 91 to open outward, and at the same time, the included angle of the V-shaped lifting frames 91 gradually decreases to reduce the height of the loudspeaker. When the control handle is controlled in the reverse direction, the control handle drives the stud 921 to rotate, the stud 921 pushes the two groups of V-shaped lifting frames 91 to tighten inward, and at the same time, the included angle of the V-shaped lifting frames 91 gradually increases to increase the height of the loudspeaker.
