Aluminum ceiling with noise reduction and sound insulation functions

JIN YIRONG

The invention relates to the technical field of aluminum ceilings, and discloses an aluminum ceiling with noise reduction and sound insulation functions. The aluminum ceiling with the noise reduction and sound insulation functions comprises a body, a sound absorption box is arranged on the outer surface of the body, a first sound absorption cavity is formed in the inner side surface of the sound absorption box, a second sound absorption cavity is formed in the inner side surface of the sound absorption box, Through holes are formed in the inner side face of the sound absorption box, sponge blocks are arranged on the inner side face of the sound absorption box, sound absorption cotton is arranged on the inner side face of the sound absorption box, sound absorption grooves are formed in the outer surface of the sound absorption cotton, and a sound insulation plate is arranged at the bottom of the sound absorption cotton; through the design of the through holes, external noise can enter the through holes and continuously flow in and out of the first sound absorption cavity, the second sound absorption cavity and the third sound absorption cavity through the through holes, so that the noise is absorbed under the oscillation action of the through holes and the three sound absorption cavities, most of the noise can be absorbed under the cooperation action of the sponge blocks, therefore, the aluminum ceiling has a certain noise reduction function.

本发明涉及铝天花板技术领域，且公开了一种具有降噪隔音功能的铝天花板，包括本体，所述本体的外表面设置有吸音盒，吸音盒的内侧面开设有吸音腔一，吸音盒的内侧面开设有吸音腔二，吸音盒的内侧面开设有吸音腔三，吸音盒的内侧面开设有通孔，吸音盒的内侧面设置有海绵块，吸音盒的内侧面设置吸音棉，吸音棉的外表面开设有吸音槽，吸音棉的底部设置有隔音板；通过通孔的设计，使得外界噪音可以进入通孔中，并通过通孔不断的进出流动在吸音腔一、吸音腔二、吸音腔三的内部，从而在通孔以及三个吸音腔的震荡作用下对噪音进行吸收，并海绵块的配合作用下可以对大部分噪音进行吸收，从而使得铝天花板具有一定的降噪功能。
