Title (EN) ACTUATOR FOR DISTRIBUTED MODE LOUDSPEAKER WITH EXTENDED DAMPER AND SYSTEMS INCLUDING THE SAME
(FR) ACTIONNEUR POUR HAUT-PARLEUR À MODE DISTRIBUÉ AVEC AMORTISSEUR ÉTENDU ET SYSTÈMES COMPRENANT CELUI-CI
Abstract:
(EN) A system includes a panel extending in a plane, an actuator attached to a surface of the panel, and an electronic control module to activate the actuator to cause vibration of the panel. The actuator includes: a plate to create a force to cause vibration of the panel to generate sound waves, having a width, WT, at a first edge; a stub extending from the first edge of the plate, having a width at a region of connection to the plate that is less than WT, the stub being attached to the surface of the panel to transfer the force received from the plate to the panel and cause the panel to vibrate; and a damper supported by a surface of the plate facing the panel coupling the plate to the panel, the damper having a width greater than WS.
(FR) L'invention concerne un système comprenant un panneau s'étendant dans un plan, un actionneur fixé à une surface du panneau, et un module de commande électronique pour activer l'actionneur pour provoquer une vibration du panneau. L'actionneur comprend : une plaque pour créer une force pour provoquer une vibration du panneau afin de générer des ondes sonores, ayant une largeur, WT, au niveau d'un premier bord; un embout s'étendant depuis le premier bord de la plaque, ayant une largeur à une région de connexion à la plaque qui est inférieure à WT, l'embout étant fixé sur la surface du panneau pour transférer la force reçue de la plaque au panneau et provoquer la vibration du panneau; et un amortisseur supporté par une surface de la plaque faisant face au panneau couplant la plaque au panneau, l'amortisseur ayant une largeur supérieure à WS.
