[0016] The manufacturing method of the light-transmitting sandstone sound absorption plate specifically includes the following steps:

[0017] S11, making the original mold of the light-transmitting sandstone sound-absorbing plate substrate: first, making an electronic drawing on a computer, drilling holes in a synthetic medium-density fiberboard or a steel plate by using a numerical control engraving machine to obtain the original mold required according to the drawing;

[0018] S12, re-molding the original mold by using liquid silica gel, and obtaining a flexible silica gel mold after re-molding;

[0019] S13, placing the flexible silica gel mold into a synthetic medium-density fiberboard mold with an inner cavity size equal to that of the flexible silica gel mold, and the surrounding edge of the mold being higher than the flexible silica gel mold, and manually inserting PMMA optical fibers into the holes of the silica gel mold;

[0020] S14, preparing a quartz sand polymer cementing material;

[0021] S15, manually pouring the quartz sand polymer cementing material into the mold, heating and forming by using a constant-temperature oven, naturally cooling and curing after being taken out of the oven, demolding after reaching the target strength, and cutting, polishing and polishing to become a light-transmitting sandstone sound-absorbing plate;

The sound absorption panel can not only provide good sound absorption effect, but also emit soft light to create a warm and comfortable space atmosphere. This design meets the dual needs of modern buildings for aesthetics and functionality.

[0029] Convenient installation: the light-transmitting sandstone sound absorption panel of the present application realizes convenient fixing and disassembly through the first fixing assembly and the second fixing assembly. The first fixing assembly can firmly fix the side of the sound absorption panel through the design of the L-shaped insert block and the side plate. The second fixing assembly can conveniently control the front fixing and disassembly of the sound absorption panel through the design of the adjusting bolt and the block. In addition, the design of the control assembly can further simplify the disassembly process and improve the construction efficiency.

[0030] Convenient maintenance: since the light-transmitting sandstone sound absorption panel of the present application adopts a convenient disassembly design, when the sound absorption panel needs to be replaced or the rear light source assembly needs to be maintained, the original installation structure does not need to be damaged, reducing the maintenance cost and difficulty. At the same time, this design also facilitates users to replace or upgrade the sound absorption panel without damaging the wall or steel structure.
