Title (EN) MITIGATING EFFECTS OF CAVITY RESONANCE IN SPEAKERS
(FR) ATTÉNUATION DES EFFETS DE LA RÉSONANCE D'UNE CAVITÉ DANS DES HAUT-PARLEURS
Abstract:
(EN) The technology described in the document can be embodied in a speaker that includes a housing, at least one electro-acoustic driver including a diaphragm, and a cover secured to one or more of the housing and driver. The cover is configured to partially extend over the diaphragm to affect an associated cavity resonance frequency of an air cavity adjacent to the diaphragm.
(FR) L'invention concerne un procédé pouvant être implémenté dans un haut-parleur comprenant un boîtier, au moins un élément d'entraînement électroacoustique comprenant une membrane, et un couvercle fixé au boîtier et/ou à l'élément d'entraînement. Le couvercle est configuré pour s'étendre partiellement sur la membrane et affecter ainsi une fréquence de résonance de cavité d'une cavité d'air adjacente à la membrane.
