Abstract: A resonator for a vehicle, which reduces intake noise by using a resonance chamber for frequency tuning, includes an outer pipe having a first outer pipe with an inlet for introducing external air and a second outer pipe with an outlet for discharging the air introduced into the inlet to outside, an inner pipe disposed inside the outer pipe and having a plurality of slits for giving a passage of air, and an expansion pipe inserted between the outer pipe and the inner pipe to partition a space between the outer pipe and the inner pipe into a plurality of spaces and thus partition the resonance chamber into a plurality of regions.

Abstract: The present disclosure relates to a resonator, and more particularly, to a resonator installed at the rear of a turbo charger of a vehicle and combined with a Helmholtz resonator and a groove type resonator to attenuate both high-frequency noise and low-frequency noise. The resonator installed at the rear of a turbo charger of a vehicle to attenuate an inhaling noise includes: at least one Helmholtz resonator having a cavity in an air introduction path extending into a duct so that the cavity is formed in a radial direction of the duct; and at least one groove type resonator provided at the rear of the Helmholtz resonator and protruding outwards in the radial direction of the duct.
