  • Systems and methods for active exhaust noise cancellation
    Patent number: 9286882
    Abstract: A controlled noise source is for attachment to an exhaust pipe of a vehicle. The noise source comprises an axially compliant member that couples to the exhaust pipe such that an enclosed internal volume of the axially compliant member is in fluid communication with the interior of the exhaust pipe. A dynamic driver is coupled to the axially compliant member. The dynamic driver oscillates the axially compliant member so as to vary the internal volume of the axially compliant member and thereby introduce controlled pressure waves to the interior of the exhaust pipe that counteract sound produced by the engine.
