Single-chamber multiple-resonant-frequency bypass resonant silencer

The invention belongs to the field of machine control technology, and discloses a single-chamber multiple-resonant-frequency bypass resonant silencer. The silencer is provided with a protective housing, a noise detector, a cladding housing, a magnetic inner ring and magnetic particles. The noise detector is arranged at the right side of the inner part of the protective housing. The cladding housing is arranged below the protective housing. The magnetic inner loop is arranged between the outer ring of the cladding housing and the magnetic inner ring. The magnetic particles are arranged at an unequal subpart between the outer ring of the cladding housing and the magnetic inner ring. According to the single-chamber multiple-resonant-frequency bypass resonant silencer, an engine or other large-noise equipment power generation parts are cladded by the cladding housing, and the noise volume is detected through the noise detector. The single-chamber multiple-resonant-frequency bypass resonantsilencer has advantages
