Integrated active noise attenuation system and fluid reservoir

摘要

An active noise attenuation system ( 10 ) comprises a speaker ( 26 ) in communication with a flow body ( 78 ). The speaker ( 26 ) emits an output for attenuating noise from the flow body ( 78 ). A control unit ( 31 ) communicates with the speaker ( 26 ) and controls the output. A housing ( 14 ) has one volume ( 18 ) acting as a liquid storage chamber and another volume ( 22 ) acting as a speaker chamber.
