  "textContent": "A variable wheel resonator system for a vehicle can suppress a resonance noise in a wide resonance frequency band occurring during driving of the vehicle by variably controlling an amount of air flowing from a first air chamber of a tire to a second air chamber and then flowing again to the first air chamber through an on/off control of a solenoid valve mounted on a wheel resonator. The system can suppress the resonance noise in the resonance frequency band that differs in accordance with a road-surface input frequency change (road-surface impact change) input to the tire, a driving speed and turning condition change, and a temperature change of an internal air of the tire.",
