The invention relates to a sound absorption decorative box. The sound absorption decorative box is composed of a sound absorption box, a round cup sound insulation board and a cover plate, wherein thesound absorption box and the cover plate are assembled together; the round cup sound insulation board is arranged between the sound absorption box and the cover plate; a circle of L-shaped openings II in the inner face of the cover plate are formed in a circle of L-shaped openings I in the back face of the sound absorption box and are in butt joint together; a plane is formed by the back face ofthe cover plate and the upper faces of the circle of L-shaped openings I; eight fixing pipes on the inner face of the cover plate penetrate eight semicircular grooves in the periphery of the round cupsound insulation board and correspondingly sleeve eight positioning columns of the sound absorption box and are bonded to the eight positioning columns of the sound absorption box together through glue, and the sound absorption box, the round cup sound insulation board and the cover plate are fixed into a whole; and various sound waves are absorbed through a plurality of sound absorption counterbores of the sound absorption box and then enter a large-diameter sound insulation cup and a small-diameter sound insulation cup, sound wave energy is consumed through sound wave reflection interference, the sound waves are weakened to a great degree, the sound wave energy is reduced, and the purpose of noise blocking is achieved.
本发明涉及一种吸声装饰盒,由吸音盒、圆杯隔声板、盖板构成;将吸音盒和盖板组装在一起,在吸音盒和盖板之间设有圆杯隔声板,盖板内面的一圈L形口Ⅱ置于吸音盒背面一圈L形口Ⅰ内对接在一起,盖板的背面与一圈L形口Ⅰ的上面构成一个平面,盖板内面的八个固定管分别穿过圆杯隔声板周边的八个半圆槽对应的套在吸音盒八个定位柱上通过胶粘接在一起,将吸音盒、圆杯隔声板和盖板固定为一体;各种声波通过吸音盒数个吸音沉孔吸声再进入到大直径的隔声杯和小直径的隔声杯后,通过声波反射干涉消耗掉声波能量,使声波极大程度减弱,降低声波能量,达到阻隔噪声的目的。
