\n

The surface is evenly perforated with ultra-micro holes of 0.2mm. Sound waves enter the micro-holes and generate friction with the air, dissipating energy and achieving resonant sound absorption.<\/strong><\/p>\n\n\n\n

\n
\n

Sound Energy Conversion:<\/strong> After sound waves enter the micro-holes, they cause friction and resonance within the air layer in the back cavity, converting sound energy into thermal energy that is then dissipated.<\/p>\n<\/div>\n\n\n\n

\n

Fiber-Free Construction:<\/strong> Eliminates traditional acoustic cotton and relies solely on an all-metal structure combined with an air layer for sound absorption, preventing performance degradation caused by material aging.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
