ABSTRACT:
A vibration producing system for use in vibratory furniture and including first and second vibrator motors for producing vibrations upon being energized, a full wave rectifier having input terminals connected to the power supply and a pair of output terminals for providing full wave rectified current. A first switch has a first mode for connecting the first vibrator motor to the output terminals, a second mode for connecting the vibrator motor to the rectifying means so that the first vibrating means receives alternate half waves of the alternating current having a first polarity and a third mode for open circuiting the first vibrator motor. A second switch has a first mode for connecting the second vibrator motor to the output terminals, a second mode for connecting the second vibrator motor to the rectifying means so that the second vibrator motor receives alternate half waves of the alternating current having a second polarity, and a third mode for open circuiting the second vibrator motor.
