Louver with noise lowering function
The invention discloses a louver with the noise lowering function. The louver comprises a louver body in which sound absorbing sponge and a plurality of blades are arranged, the sound absorbing sponge is installed on the inner side of the louver body, the blades are arranged on the portion, on the two sides of the sound absorbing sponge, of the louver body in parallel, the included acute angle between the joints of the blades and the louver body and the louver body is 60-75 degrees, and the blades are of a bent structure bent towards the sound absorbing sponge. According to the louver with the noise lowering function, due to the fact that the sound absorbing spine adheres to the inner side of the louver body and the bent blades are obliquely arranged on the portion, at the two ends of the sound absorbing sponge, of the louver body, when noise passes the blades, the noise can be refracted to the sound-absorbing sponge along the blades, after a large amount of energy of the noise is absorbed by the sound-absorbing sponge, the energy of the noise is very low, and therefore it can be guaranteed that the noise is low in energy when reflected again by the sound absorbing sponge, and therefore a good noise lowering effect is achieved.
