The invention discloses a bridge hole reflection sound-absorbing alloy plate which comprises a base plate and bridge holes uniformly arranged on the base plate in a dotted manner, arched reflecting surfaces are arranged on the bridge holes, plane reflecting surfaces are arranged among the bridge holes, the diameter of the bridge holes is twice larger than the thickness of the plate, the distance between the bridge holes is larger than the hole diameter, and the hole height of the bridge holes is larger than the thickness of the plate. According to the invention, the principle that the arched reflecting surface is favorable for generating diffuse reflection to increase the sound fullness and the sound cannot return in a curve after entering the hole is utilized, the noise reduction coefficient without adding the sound absorption cotton reaches 0.6, the sound reflectivity reaches 0.4, the fire resistance reaches grade A, the environmental protection reaches grade E, the sound absorption cotton is free of aging attenuation and pollution, the hardness is high, the deformation is not easy, and the surface can be customized according to designed colors, patterns and shapes; installation is easy and fast, the splicing function is achieved, and waste can be recycled. The sound-absorbing board is suitable for being installed in gymnasiums, machines, boats, vehicles and boats, decoration of public buildings such as living rooms, texts, teachers, guards, hotels and the like and home decoration, and is an excellent product for replacing perforated aluminum boards, wood, soft-package sound-absorbing boards and mineral wool.
本发明公开了桥孔反射吸音合金板，包括基板、基板上点状均匀排列的桥孔，桥孔上有拱形反射面，桥孔之间为平面反射面，桥孔直径大于板厚二倍，桥孔间距大于孔径，桥孔的孔高大于板厚，本发明运用拱形反射面有利于产生漫反射来增加声音丰满度和声进孔后不能曲线返回的原理，不加吸声棉的降噪系数达0.6、声反射率达0.4、防火达到A级、环保达到E级，无老化衰减、无污染、硬度高不易变形，表面可按设计色彩、图案、造型定制，安装简单快捷，具有拼装功能，废品可回收利用。适合在体育馆、机、船、车、艇内装及候客厅、文、教、卫、宾馆等公共建筑装修和家庭装修，是取代穿孔铝板、木质和软包吸音板、矿棉的优良产品。
