A vibrator is disclosed for mounting on furniture in which a pair of vibrator motors is each mounted to an independent long relatively rigid resonator member capable of transmitting vibrations, the two long resonators for the respective motors being parallel to one another and mounted by non-rigid means such as a sheet of cardboard or springs to the remainder of the structure of the furniture. One form of complete unit comprises a non-rigid sheet containing two rigid rods each associated with an off-center vibrating motor, which underlies the surface of the furniture contacted by the user. A vibrator controller supplies the two vibrator motors with 60 Hertz pulsed D.C. current which is amplitude modulated at approximately 16 cycles per minute, with the modulation supplied to one motor 180 out of phase with the other motor so that the user experiences the sensation of moving wave. The user simultaneously receives a 10 to 30 cycle per minute alternating tactile stimulation, and a 60 Hertz audio wave which is amplitude modulated at 10 to 30 cycles per minute. The effect is somewhat similar to a Yoga chant and induces relaxation and a slower breathing rate. Other forms use rigid linear resonators attached to each vibrator and placed parallel to one another but not a permanent part of the furniture with which they are used. |
