Ultra-narrow frame Micro-perforated sound-transmitting picture frame screen

YUETMEI sound-permeable screen utilizes original German imported fabric, with its base material crafted from imported PVC raw materials. It undergoes initial shaping by a professional high-precision screen machine, followed by processing with a professional punching machine. This results in evenly punched holes on the screen surface, enhancing sound penetration and ensuring smooth sound transmission. The punched holes are closely spaced and small in diameter, without affecting the projection quality. The light reflectance is extremely low, providing rich and delicate shades, high contrast, vivid and bright colors without glare, clear depth of field, and a full three-dimensional texture. The effective viewing angle reaches up to 175 degrees, truly reproducing true colors. The screen surface is soft and flat, resistant to deformation, and features a pure color tone. This imported high-definition sound-permeable screen boasts high clarity and high contrast, making it ideal for high-definition professional cinema screenings. The product is fireproof, flame retardant, mold-resistant, and environmentally friendly. It has been widely applied in various image display environments such as performance and entertainment centers, villa cinemas, and various large-scale theater stages. It is easy to use and clean.
