Single-cavity multi-resonant-frequency lateral-support resonant muffler

A single-cavity multi-resonant-frequency lateral-support resonant muffler belongs to the field of the control of automobile noise and mainly consists of a main pipe, a resonator, a diaphragm, a pressing plate and a connecting screw assembly. According to characteristics of an air inlet noise source and the distribution situation of an engine cabin, a resonator cavity can be designed into a cylindrical shape and a hexagonal shape. When the resonator cavity is a cylindrical cavity, the cylindrical bottom surface is completely or partially covered by the thin diaphragm, and two resonant frequencies can be obtained by optimizing the size and the thickness of the diaphragm; and when the resonator cavity is a hexagonal cavity, at most five surfaces of the resonator are substituted by the thin diaphragm, and more than one and less than five resonant frequencies can be obtained. The single-cavity multi-resonant-frequency lateral-support resonant muffler has characteristics that through the method by utilizing the thi
