摘要
A game ball (10) that can count and indicate the number of times the ball has been hit by a player(s). The game ball includes an impact detector (18) located within a ball housing (12). The impact detector (18) can detect each time the ball housing (12) is hit. The impact detector (18) is coupled to a circuit (20) that can count each impact detection. The circuit drives an output device (26, 28) to indicate, visually and/or audibly, a number of detected impacts. This allows a player(s) to determine the number of times the ball is successively hit without having to manually count during play of the game.
