Tires with self generation and sound absorption

A tire with self-generation and sound absorption, the tire comprising:

• a wall structure disposed on a surface of an inner liner of the tire;
• a sound absorber spaced apart upward from the inner liner with both ends coupled to the wall structure and configured for blocking sound generated by surfaces of treads and a road surface;
• and
• an electronic unit disposed on the surface of the inner liner and positioned between the inner liner and the sound absorber,
• wherein the sound absorber includes:
• a polymer film shaped sound absorption member;
• couplers formed at both ends of the sound absorption member to be coupled to the wall structure;
• and
• second wires disposed in the couplers,
• wherein the second wires are configured to generate electrical energy through frictional electrification with bodies having a porous sponge structure.
