Abstract

The invention relates to a car silencer. The car silencer is characterized by comprising a shell; a front baffle and a back baffle are arranged in the shell, and the shell is divided by the front baffle and the back baffle into a front cavity, a middle cavity and a back cavity; an air inlet pipe spans the front cavity to be erected and penetrates the middle cavity to extend to the back cavity; an air outlet pipe spans the back cavity to be erected and penetrates the middle cavity to extend to the front cavity; and the middle cavity is filled with acoustic materials. According to the car silencer, on the premise that the air exhaust back pressure is not increased, the better inhibitory effect on the high frequency and the specific low frequency content of the exhaust noise is achieved, and the manufacturing process is simple.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to an automobile noise reduction device. Background technique [0002] At present, urban noise pollution is serious, the number of automobiles is developing rapidly, the number of automobiles is increasing, and factory production has no noise treatment. Therefore, it is still of great significance to reduce noise from automobiles and factories. However, the current muffler has a complicated structure and high cost, which is not conducive to widespread use. . Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an interference muffler with simple structure and low cost. Can be widely used in noise reduction occasions. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a vehicle muffler structure, including a housing, a front baffle and a r...
