The invention discloses an environment-friendly fireproof acoustic board which comprises a bottom board and a base board, the bottom board and the base board are made of metal materials, the thickness of the base board is 0.5-1 cm, a plurality of arc-shaped protruding blocks are arranged on the face, away from the bottom board, of the base board, and sound absorption holes are formed in the other face, opposite to the arc-shaped protruding blocks, of the base board. The sound absorption holes and the arc-shaped protruding blocks are coaxially arranged, holes are formed in the arc-shaped protruding blocks, the width of each arc-shaped protruding block is 2-3 cm, the height of each arc-shaped protruding block is 0.5-1 cm, the fillet of each arc-shaped protruding block is 0.2-0.5 cm, the sound absorption holes are funnel-shaped, the width of each sound absorption hole is 1-2 cm, and the angle of each sound absorption hole is 30-50 degrees. According to the invention, sound waves enter the sound absorption holes through the holes, and drive air to vibrate in the sound absorption holes, so that the vibrating air is continuously converted into heat energy, the sound wave energy is attenuated, the sound waves are reflected by the arc-shaped convex blocks to avoid sound gathering, and the bottom plate and the base plate made of metal materials have good fireproof performance and are environment-friendly.
本发明公开了一种环保型防火吸声板，包括底板与基板，所述底板与所述基板由金属材料制成，所述基板厚度为0.5‑1cm，所述基板远离所述底板一面上设置有多个弧形凸块，所述基板相对所述弧形凸块另一面上开设有吸声孔，所述吸声孔与所述弧形凸块同轴线设置，所述弧形凸块上设有孔隙，所述弧形凸块宽度为2‑3cm，高度为0.5‑1cm，圆角为0.2‑0.5cm，所述吸声孔为漏斗状，宽度为1‑2cm，角度为30‑50度。在本发明中，声波通过孔隙进入吸声孔内，声波在吸声孔内带动空气振动，使振动空气动气不断转化为热能，从而使声波能量衰减，同时声波经过弧形凸块的反射避免了声聚集，金属材料的底板与基板具有良好的防火性能且环保。
