[0031] REFERENCE Figures 1-5A linear array full-range speaker column includes a base plate 1, a rotating seat 2 fixedly connected to the top of the base plate 1, rotating rods 3 rotatably connected to both ends of the top of the rotating seat 2, fixed rods 4 fixedly connected to the upper and lower ends of the rotating rods 3, and support columns 5 fixedly connected inside the fixed rods 4. Multiple sets of support columns 5 are arranged equidistantly and fixedly connected inside the fixed rods 4. Audio equipment 6 is rotatably connected to the outer sides of the rotating rods 3 and support columns 5. A sliding rail 8 is fixedly connected to the outer side of the fixed rods 4 at the lower end of the rotating rods 3. A sliding groove 9 is provided inside the sliding rail 8, and a connecting block 10 is slidably connected inside the sliding groove 9. A support rod 11 is rotatably connected to the end of the connecting block 10, with the other end of the support rod 11 connected to the connecting block 10 on the other side. The support rod 11 is slidably connected to the top of the base plate 1. In its initial state... In its normal state, the fixed rod 4 at the top of the base plate 1 rotates around the rotating rod 3 directly above the base plate 1. At the same time, the two fixed rods 4 are parallel to each other, with the support rod 11 located at the end of the fixed rod 4. This state facilitates handling by staff. When in use, after moving it to the position to be used, the support rod 11 is pushed to move it towards the rotating rod 3. At this time, the support rod 11 drives the connecting blocks 10 on both sides to slide inside the sliding groove 9, thereby driving the fixed rod 4 to rotate around the rotating rod 3 outward from the base plate 1. Depending on the needs of the site, the fixed rod 4 can be unfolded into a V-shape or a straight line to ensure full sound coverage of the site. Since the audio equipment 6 is rotatably connected to the outside of the support column 5 and the rotating rod 3, the orientation of the audio equipment 6 can be adjusted according to the unfolded shape of the fixed rod 4 to ensure the best sound dispersion direction.
