Audio is a simplified daily word and the abbreviation of audio system, which refers to a complete set of equipment that can restore and play audio signals. With the progress of society, people yearn for a more colorful life. Singing and dancing, as a form of entertainment that has been passed down for thousands of years, has penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing.

[0046] Preferably, a longitudinal groove 704 is provided on the rotating base plate 505, and a matching strip 705 matching with the longitudinal groove 704 is provided on the mounting tube 606, and this arrangement enables the mounting tube 606 to be displaced in the longitudinal direction.

[0049] Operation process: When installing two sound bodies, the operator first installs the connecting buffer component 500 into the installation tube 606, and then the operator drives the first motor so that the first motor drives the rotation of the driving plate 202. When the driving plate 202 rotates, it will drive the synchronous rotation of the second guide groove 401. The rotation of the second guide groove 401 will change the position of the gap formed by the intersection with the first guide groove 400, and the position of the gap will gradually move from the center position close to the fixed plate 201 to the edge position close to the fixed plate 201, so that the moving path of the plug rod 403 is from the center to the edge. The edge will drive the position of the lower end block 404 to move, and then drive the position of the connecting rod 102 to move, so as to achieve extension or retraction, and then the operator will start the stepper motor to drive the rotating block 504 to rotate, so that the connecting vibration damping cylinder 501 moves downward, and then the abutting card plate 603 moves toward the direction of the installation cylinder 606, and then it will drive the movement of the extending rod 607, so that the second inclined surface 702 and the first inclined surface 701 will have an inclined surface effect, so as to drive the insertion rod 700 to slide downward, so as to push the connecting bottom plate 608 outward, so as to approach the audio body, thereby completing the two docking operations.

[0050] The two speaker bodies can be connected by using the connecting buffer component 500, and when connecting, the operator can adjust the extension distance of the abutting card plate 603, so that the connection between the two speakers has a certain distance and tightness, and then the vibration of the speakers can be buffered in cooperation with the vibration reduction of the vibration reduction component 200, thereby reducing damage to the speakers caused by the vibration of the speakers during playback.
