Foamed aluminum sound reflecting cover
The invention provides a foamed aluminum sound reflecting cover which comprises a sound reflecting cover plate and a light filling core body. The sound reflecting cover plate comprises a front cover plate, a rear cover plate, a left cover plate and a right cover plate which are made of metal materials, and a filling cavity defined by the front cover plate, the rear cover plate, the left cover plate and the right cover plate, and the width of the filling cavity is 5 mm to 20 mm; the light filling core body is arranged in the filling cavity; and the sound reflecting cover plate and a foamed aluminum plate are both of an arch-shaped structure. The foamed aluminum sound reflecting cover has the beneficial effect that the foamed aluminum plate is ingeniously used for replacing an aluminum honeycomb core sandwich plate, various performance indexes of the sound reflecting cover are improved, and the sound reflecting cover is high in strength, light in weight and convenient to assemble, disassemble or carry; the damping shock absorbing performance and the impact energy absorption rate are high, and the anti-collision effect is good; reversibility is good, bending can be achieved through mold pressing, machining is easy, and the manufacturing process is simple; and the foamed aluminum sound reflecting cover is flexible in installation, rapid in construction, healthy, environment-friendly, reusable, pollution-free, mothproof, good in fireproof effect, firm, durable and free of deformation such as warping.
本发明提供一种泡沫铝反声罩，包括反声罩板和轻质填充芯体，反声罩板包括采用金属材料制作而成的前罩板、后罩板、左罩板、右罩板，以及由前罩板、后罩板、左罩板和右罩板围成的填充腔体，填充腔体的宽度为5mm~20mm；所述轻质填充芯体设置在填充腔体内；反声罩板和泡沫铝板均为弓弧形结构。本发明的有益效果是，巧妙地用泡沫铝板代替铝蜂窝芯夹心板，提高反声罩的各项性能指标，具有较高的强度，质量轻，便于装拆或搬运；具有高阻尼减震性能及冲击能量吸收率，防撞击效果好；可逆性好，经模压可弯曲、易加工，制作工艺简单；安装灵活、施工快捷、健康环保、可重复使用，无污染、防虫蛀、防火效果好，不会产生翘曲等变形，坚固耐用。
