Chair mountable, low frequency transducer

摘要

A manually mountable and demountable low frequency transducer apparatus for generating low frequency vibrations in a chair or other furniture. A clamp, preferably manually operable, is attached to one end of a support arm and a vibrating transducer motor (vibrator) is attached to the opposite end so the transducer motor is supported in cantilever relation from a leg of the article of furniture. Preferably the arm has a length substantially within the range of 1 inch to 12 inches and the jaws of the clamp are oppositely concave so the transducer apparatus is mounted with the vibrator having a vertical axis of vibration. The mass and the arm may be designed to be resonant or near the operating frequency of the vibrator.
