Take use of honeycomb sandwich structure, namely stick honeycomb core to front board and back board, then paste a layer of acoustic cloth betwee them.Due to the closed rooms that honeycomb separated in the honeycomb panel, which prevent the air transport, hamper the sound waves, so that the sound-absorption coefficient enhance, and so does its intensity, allow the bigger sizes, supply more design ideas.

采用蜂窝式夹层结构，即在穿孔面板与穿孔背板间，依靠优质胶粘剂令面板、背板与铝蜂窝芯直接粘接而成，然后在蜂窝芯与两板间贴上- -层吸音布。由于蜂窝铝板内的蜂窝芯分隔成众多的封闭小室，阻止了空气流动，使声波受到阻碍，提高了吸声系数，同时提高了板材强度，使单块板材的尺寸可以做到更大，进一步加大了设计自由度。
