Title (EN) LOUDSPEAKER
(FR) HAUT-PARLEUR
Abstract: front page image
(EN)A loudspeaker comprising a housing and a membrane mounted in said housing, which membrane can be set vibrating so as to produce sound, wherein the loudspeaker has at least one sound channel which extends between the membrane and the outer side of the housing, and wherein one or more local sound barriers are provided in the sound channel, which sound barriers locally block at least 15 % of the cross-sectional area of the sound channel, such that amplification of the sound pressure occurs in the audible frequency range due to resonance.
(FR)L'invention a trait à un haut-parleur comprenant une enceinte ainsi qu'une membrane qui est montée dans cette enceinte et qui est amenée à vibrer de manière à produire un son. Ledit haut-parleur comporte au moins un canal audio qui s'étend entre la membrane et le côté extérieur de l'enceinte, et une ou plusieurs barrières sonores locales qui sont placées dans le canal audio et qui bloquent localement 15 % au minimum de la superficie de la section transversale dudit canal audio, de sorte que l'amplification de la pression acoustique se produise dans le domaine des fréquences audibles en raison de la résonance.
