Abstract
Description
Technical Field
[0001] The utility model relates to the field of tires, and more specifically, to a structure for improving the cavity noise of tires. Background Art
[0002] When a vehicle is traveling at high speed, when the tire contacts an irregular road surface or is subjected to an external impact, a relatively large noise is generated. The generated noise propagates inside the tire, and the internal air vibrates through the tire itself. In this way, the tire acts as an amplifier of sound, thereby amplifying the noise. The noise generated hereby is what we call the cavity noise of the tire. Existing tires cannot reduce the noise generated during their own use, resulting in a relatively large noise generated during tire use. This may affect the comfort of the driver and passengers, and also affect the social living environment of the city. How to improve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model
