[0002] Nowadays, computers have become a very common electronic product. Computers can not only improve people's work efficiency, but also allow them to watch movies, listen to music and play games in their spare time to relax their body and mind. However, many desktop computers now do not have audio speaker function. Even if some display screens have built-in speaker function, the sound quality is relatively average and cannot bring people a better viewing experience.

[0003] Therefore, many people choose to place speakers on the desktop to connect to the computer for external audio playback. However, in actual use, these speakers are generally placed randomly on both sides of the computer, and the audio is played through the left and right channels on both sides during use. The placement angle of the speakers has a great influence on the improvement of sound quality, and different placement positions and angles have a great impact on the auditory systems of different people. However, when in use, traditional speakers are easily moved due to accidental touches, causing the placement angle to change, which not only affects the audio-visual effect, but also is very troublesome when cleaning the desktop.
