Abstract: An alarm clock in the form of a sports ball has an alarm clock assembly with a snooze-type audio alarm which is temporarily silenced when the ball is thrown against a wall. The alarm clock ball has a feasible and resilient core of a foamed plastic, such as styrofoam, and an overlying cover of a plastic material. The clock assembly is mounted within a recess in the styrofoam core and has display and button controls which are visible and accessible through an opening in the plastic cover. The clock assembly has a quiet electrical switch which controls the snooze alarm mechanism and which is operated by a normally closed deceleration switch located in the foam core. The deceleration switch has a spring-biased metal ball in normal contact with two conductive contacts. When the alarm clock is thrown against a wall, the metal ball is displaced due to its inertia on impact thus temporarily breaking contact and silencing the alarm.
