In an active canceller system that performs noise reduction by canceling out both pressure waves by outputting compression and density pressure waves of opposite phase from a canceller speaker, the opening end surfaces of the noise outlet and the pressure wave outlet are connected to each other. An active canceller system characterized by being formed on inclined end faces in opposing directions.
