The invention's features is a suspended strap that is connected inside and between the upper and lower sides of the inner bladder. Additionally, the suspended strap's center is affixed with a balance-switching sound and light element. The sound and light element is controlled by a battery. When the ball is thrown, its movement causes the sound and light element to move and emit the sound and light effects, which will be passed through the translucent ball skin.
