Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present utility model provides an aluminum plate having a sound absorbing function as shown in fig. 1 to 5, comprising:

a panel 1, two fixing plates 3 arranged at the rear sides of the left and right ends of the panel 1, and a noise elimination chamber 4 arranged in the rear end;

fixing holes are formed in the upper side and the lower side of the fixing plate 3 and used for attracting the aluminum plate to fix;

the rear end of the noise elimination chamber 4 is internally provided with a backboard 5, and the noise elimination chamber 4 and the backboard 5 are both arranged in a convex shape;

the inside front side of noise canceling chamber 4 is connected with rebound board 7, is provided with between rebound board 7 front end and the panel 1 and inhales sound cotton 10, is provided with between backplate 5 and the rebound board 7 and inhales sound baffle 6, and the inside spacing hole 11 that all is provided with of backplate 5 front end four corners department, and four spacing hole 11 inside all is provided with spacing spring 8.

As shown in fig. 1 to 5, after the noise enters between the rebound board 7 and the panel 1 through the plurality of first sound transmission holes 2 arranged in the front end of the panel 1, the noise can be effectively absorbed and blocked through the sound absorbing cotton 10, so as to absorb a part of the noise, meanwhile, the noise can rebound and offset back and forth between the inner wall of the front end of the noise canceling chamber 4 and the outer wall of the front end of the rebound board 7, so that the intensity of the noise is reduced, the noise with reduced intensity enters the noise canceling chamber 4 at the rear end of the rebound board 7 through the plurality of second sound transmission holes 12 arranged in the rebound board 7, and finally the noise is eliminated through the blocking and absorption of the sound absorbing blocking board 6, thereby achieving the effect of noise reduction.
