  • Practice ball with sound and acceleration sensor
    Patent number: 5810685
    Abstract: A practice ball responsive to acceleration for use in practicing sports and an acceleration sensor therefor. The practice ball includes an electronics housing; an acceleration sensor mounted in the electronics housing and responsive to acceleration of the practice ball; a sound generating device also mounted in the electronics housing and responsive to the acceleration sensor; and a soft deformable shell having a shape which simulates a sports ball. The soft deformable shell, which is capable of snugly accommodating the electronics housing, may be supported by a tether line connected to the electronics housing. The acceleration sensor preferably includes at least two switching elements, each of which is responsive to a different magnitude of acceleration. The sound generating device is then responsive to the switching elements so as to emit different programmed sounds depending on which of the switching elements is/are actuated by acceleration of the practice ball.
