[0002] A speaker is a very commonly used device. Its main function is to convert electrical signals into sound signals so that people can hear the sound. The working principle of the speaker is based on the combination of electromagnetic induction and mechanical vibration. When current passes through the coil of the speaker, it will generate a magnetic field according to the principle of electromagnetic induction, which in turn drives the diaphragm of the speaker to vibrate and produce sound.

[0003] The loudspeaker used in large-scale performance environments generally has multiple speakers to expand the sound coverage. However, since the speakers are all fixed structures, their coverage and adaptability are limited. Since the performance locations of most performing groups are not fixed, and the audience gathering range is different based on different performance environments, fixed loudspeaker devices cannot better adapt to different environments. Summary of the invention
