ム。[Claims for Utility Model Registration] A noise outflow pipe connected to a noise source, a cancel speaker provided on the noise outflow pipe, and a device that monitors noise from the noise source and sends a predetermined control signal to the cancel speaker. An active canceller system is equipped with a control means for outputting noise from a noise source, and outputs compression pressure waves having an opposite phase to the noise from a cancel speaker, thereby muffling noise by canceling out both pressure waves. An active canceller system, characterized in that a plurality of the cancel speakers are coaxially installed along an axis perpendicular to the pipe axis in the middle of the noise outflow pipe.
