Abstract

The invention discloses a silencer and a vehicle with the silencer. The silencer comprises a shell, a barrel and a sound absorption material layer, wherein the shell is provided with a first opening and a second opening, the barrel is arranged in the shell, the first end and the second end of the barrel are respectively connected with the shell, an inner cavity of the barrel is communicated with the outside through the first opening and the second opening, a first separating plate is arranged on the barrel, the barrel is separated by the first separating plate into a first barrel section and a second barrel section, first through holes are formed in the first barrel section, and second through holes are formed in the second barrel section, a first cavity communicated with the inner cavity of the barrel through the first through holes is formed by the first separating plate, the first barrel section and the shell, a second cavity communicated with the inner cavity of the barrel through the second through holes is formed by the first separating plate, the second barrel section and the shell, and the sound absorption material layer is arranged in the first cavity. The silencer integrates the advantages of a dissipative muffler and a reactive muffler, and the good noise elimination effect on intermediate-frequency noise, low-frequency noise and high-frequency noise is achieved.

Description

technical field [0001] The invention relates to the field of noise reduction for vehicles, in particular to a muffler and a vehicle with the muffler. Background technique [0002] The muffler of the vehicle air intake system in the related art has a single structure, and the muffler frequency cannot cover the entire frequency band, and the muffler effect needs to be further improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a muffler which has a good muffler effect on medium, low and high frequency noises. [0004] Another object of the present invention is to provide a vehicle using the above-mentioned muffler. [0005] The muffler according to the present invention comprises: a casing having a first opening and a second opening; a cylinder disposed inside the casing, and the first end and the seco...
