CA 2200559

An ultra quiet vacuum cleaner having a bag cavity (44), a motor/blower chamber (48) connected to said cavity by a flexible coupling (47) and an active, adaptive noise cancellation controller (52) so configured to quiet the exhaust of the air used to cool the motor/blower unit. Fast compensation and feedback compensation allow use of a straight, short duct (51) for superior cancellation performance.

La présente invention concerne un aspirateur ultra-silencieux. Il comprend une cavité (44) pour le sac, un compartiment moteur-soufflante (48) relié à ladite cavité par un conduit de jonction souple (47), et un dispositif actif et adaptatif (52) de commande de la neutralisation du bruit, conçu de telle façon qu'il rende silencieux l'échappement de l'air utilisé pour refroidir l'unité moteur-soufflante. Une compensation rapide et une compensation par réaction permettent d'utiliser un conduit court et rectiligne (51) pour obtenir des résultats supérieurs en neutralisation du bruit.
