A modified ball structure has a base, a transparent hard inner body, a light emission control module, a transparent rubbery intermediate body and a spherical transparent outer body. An accommodation room is disposed on the base for installing the light emission control module thereon. More than two fixing components are annularly disposed outside the accommodation room. The transparent rubbery intermediate body is a soft rubber with resilience and shock-absorbing effect, and sheathes the surface of the transparent hard inner body. The spherical transparent outer body is a plastic body with a low flying resistance coefficient, and sheathes the surface of the transparent rubbery intermediate body. A better performance of the ball can be thus accomplished through the design of the three-layered structure.
