Abstract

The invention discloses a novel automobile muffler, which comprises a muffler shell, the muffler shell is a cylindrical structure with a cavity inside, and a folded sound-absorbing plate is installed on the inner wall of the cavity. The inner wall of the cavity is equipped with an arc-shaped sound-absorbing plate, and a sound-absorbing hole A is provided at the middle position of the folded-shaped sound-absorbing plate, and a sound-absorbing hole B is opened at the middle position of the described arc-shaped sound-absorbing plate; An air intake cylinder is installed on the upper end of the muffler housing, a muffler element is connected to one end of the air intake cylinder, and a plurality of damping holes are evenly opened on the muffler element, and an air outlet cylinder is installed at the lower end of the muffler housing. The present invention is provided with a folded sound-absorbing plate and an arc-shaped sound-absorbing plate, and is provided with a sound-absorbing element, and a damping hole is opened on the sound-absorbing element. When the sound wave enters the sound absorber, it can effectively reduce the energy of the sound wave and reduce the noise.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a novel automobile muffler. Background technique [0002] The muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission, and is an important measure to eliminate aerodynamic noise. Mufflers can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. There are many types of mufflers, but the muffler mechanism can be divided into six main types, namely resistive muffler, resistive muffler, impedance composite muffler, micro-perforated plate muffler, small hole muffler and active silencers. The sound-absorbing effect of present muffler needs to be further improved. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a novel automobile muffler. [0004] The present invention is realized through t...
