ABSTRACT:
A vibration cancellation mount for use in a vibration cancellation system is provided that includes a fluidic driver providing a modulated air stream to an elastomeric air spring. The pressure of the air stream is caused to fluctuate by an acoustical cancelling signal generated by an electroacoustic transducer electrically coupled to cancellation controller. As this pressure varies the air spring is filled and vented so that it responds at the same frequency and phase as the cancellation signal and thereby cancels the vibrations emanating from a vibrating structure mounted thereto. By employing a fluidic driver, the vibration cancellation mount is not frequency limited and can cancel vibrations having frequencies anywhere in the audio frequency spectrum.
