[0002] With the continuous advancement of modern audio technology, line array speakers are increasingly used in large-scale performances, conferences, sporting events, and other venues. By arranging multiple speaker units vertically in a straight line, line arrays achieve uniform sound coverage and long-distance propagation, providing a superior audio experience. This speaker system not only meets the sound field requirements of large spaces, but also adapts to different venue layouts through its flexible modular design.

[0003] While existing line array speakers offer excellent audio performance, they still face several technical challenges in practical application. First, during installation and adjustment, existing line array speakers lack effective fixing and angle adjustment mechanisms, which can easily cause the speakers to shift or tilt, affecting the stability and consistency of the sound, especially in situations where frequent movement is required, such as tours and temporary events. Second, existing line array speakers lack adequate structural protection. Most speakers only feature a protective screen on the front panel, with no effective protection on the sides and back. This can easily damage the internal speaker units, and poor heat dissipation can also affect sound quality and device lifespan. Utility Model Content
