Abstract
A wheel for reducing a resonance noise in a vehicle may include a cylindrical-shaped rim on which a tire is mounted, and waveguides mounted on the rim, disposed in a cavity which is a space between the rim and the tire, having a ‘U’-shaped internal passage through which a sound wave generated in the cavity enters, and configured to reflect the sound wave entering the internal passage to generate a sound wave having an inverse phase, wherein a center portion of the internal passage extends in an axial direction of the rim, and first and second end portions of the internal passage are connected to a center portion of the internal passage to allow the sound wave to propagate and extend in a circumferential direction of the rim.
