Ultrasonic welding type wheel resonator

A wheel resonator assembly for reducing a resonance phenomenon inside a tire of a vehicle, comprising a plurality of wheel resonators mounted to a tire wheel,

• wherein first and second wheel resonators of the plurality of wheel resonators are fixed with each other by a fastening part including a protrusion disposed on an end of the first wheel resonator penetrating through a hole disposed in an end of the second wheel resonator,
• wherein an end portion of the protrusion has a size greater than a size of the hole,
• wherein each of the first and second wheel resonators includes first and second support portions each curvedly extending at opposite sides of the each of the first and second wheel resonators toward a support wall of a rim portion of the tire wheel,
• wherein each of the first and second support portions is formed with a hook portion at an opposite distal end thereof and the support wall of the rim portion is formed with first and second flange portions along an inner surface thereof,
• wherein the hook portion of the first support portion is configured to be assembled to the first flange portion of the rim portion of the tire wheel by forcing the hook portion of the first support portion to be coupled and supported by the first flange portion of the support wall at one side of the rim portion,
• wherein the hook portion of the second support portion, opposite to the first support portion supported by the first flange portion of the support wall, is spaced apart from the second flange portion of the support wall of the rim portion, and
• wherein the wheel resonator has a flat tube structure having a closed resonance chamber with a predetermined internal volume.
