The present invention relates to a vehicle resonator which can easily change an attenuation frequency of noise and a vehicle air cleaner having the same.
An intake system of a vehicle includes an intake duct for supplying outside air to an engine, an air cleaner for filtering out foreign matter from the outside air flowing through the intake duct, and a resonator for reducing intake noise.
The resonator attenuates noise and pulsations at specific frequencies by using the resonance principle. That is, the resonator functions to reduce the noise and pulsation of intake air in a state where the resonator is installed in an intake duct or a case of the air cleaner connected to the engine.
Since the resonator installed in the intake system of a conventional vehicle has a predetermined internal volume, its function is limited to attenuating noise at a specific frequency. Also, since the resonator is integrated with the intake duct or the air cleaner case, it is difficult to separate and replace the resonator. Therefore, in order to change the frequency of the resonator by adjusting the volume of the resonator, the air cleaner case or the like need to be newly manufactured.

When noise improvement of the vehicle intake system is required, the resonance container 210 can be replaced with another one having a different internal volume, so that the attenuation frequency of the intake noise can be easily adjusted. Since the resonator 200 of the present embodiment allows the resonance container 210 to be separated and replaced in a sliding manner, the driver or the maintenance engineer can easily tune the resonator 200. Therefore, the performance of the vehicle NVH (noise, vibration, harshness) can be easily improved in accordance with the requirements of the driver or passenger.
