WATERBED VIBRATOR Abstract of the Disclosure A vibrator mechanism, including a transducer and driving circuit, particularly adapted to vibrating a waterbed, includes two independently controlled vibration sources, each of which can generate vibration of varying amplitude and frequency. These two sources are typically mounted at opposite ends of a waterbed frame and vibrated at different frequencies so that interference waves may be produced within the water of the bed to produce a pleasing effect for the user. Additional circuitry is described which provides a time varying frequency and amplitude for each of the vibrators, and this circuitry is in turn controlled by a clock circuit so that, by using the time varying frequency and amplitude, the user may be slowly lulled to sleep or slowly awakened using the vibration within the waterbed as a stimulus for controlling the rate of falling asleep and waking up.
