ABSTRACT:
Within an easily hand gripped alarm clock, preferably of a soft sperical exterior shape, a shakeable switching means. A first standard alarm is silenced by laterally shaking the clock, and a second moaning sound is emitted after the lateral shaking. A grimacing face imprinted on the round clock face enhances the cathartic effect. The laterally shakeable switch is an enclosed container of mercury with an alarm contact in the central lower bowl and an elevated surrounding trough sloping into the bowl through a channel containing electrical contacts for the second moan sound. The mercury makes and breaks the contacts. An alternative laterally shakeable switch provides an electrically conductive sphere within an enclosed container having a bottom indentation with alarm contacts and an upwardly sloping surrounding spiral trough with parallel track contacts for the moan sound in the bottom of the trough. The sphere connects either sound producing contact pair. Another alternate laterally shakeable switch provides a conductive pendulum contacting a conductive spring in a stationary position completing a circuit to a first standard alarm. Laterally shaking the pendulum moves it away from the spring into contact with an electrically conductive surrounding truncated cone to make a connection to a second sound-producing circuit. The pendulum makes and breaks the connections. A timer delay may be added so that the second sound-producing circuit remains activated for a brief time interval after the pendulum is no longer in contact with the cone.
