Electronic ball

 for the blind

The electronic ball can be heard not only while moving but also for about 30 seconds after it comes to a stop. The electronic jingle reacts to the movement of the ball by making a sound. When the ball stops, the sound changes into a regular beep. This makes the ball easy to find for blind people.
