Micro-perforated sound-transmitting picture frame screen

The sound-permeable screen for punching is made of imported PVC raw material and sourced from Germany. It undergoes initial shaping by professional machines and is then processed with high-precision professional punching machines. This screen features evenly distributed punching holes, which enhance sound penetration and ensure smooth sound transmission. The punching is tight and the hole diameter is small, ensuring no impact on projection quality. With extremely low light reflectance, the screen offers rich and delicate shades, high contrast, and a pronounced depth of field, truly reproducing true colors. The screen surface is soft and flat, resistant to deformation. This product boasts fireproof, flame-retardant, mold-proof, and environmentally friendly properties.
