Abstract: This invention relates to a ball body which essentially comprises a transmitting hollow inner bladder. A recessed socket for accommodation of a vibration-powered luminous body is provided on the transmitting hollow inner bladder. A superficial layer is further wrapped on outside surface of the transmitting hollow inner bladder, which has transmitting areas provided thereon. When the ball body is played to produce vibration, the vibration-powered luminous body is lightened and light is scattered out through the transmitting hollow inner bladder and the transmitting areas on the superficial layer so as to increase more fun in playing the ball and diversified functions of toy.
