Abstract:
(EN) A loudspeaker arrangement includes an air-tight, rigid, thermo- conductive enclosure (103) with an aperture (115) and an outer surface, and a loudspeaker (101) air-tightly mounted in the aperture (115) to form a locked acoustic volume within the enclosure (103). The arrangement further includes a multiplicity of thermo-conductive fins (112) attached to or integrated in the enclosure (103) at the outer surface thereof. The multiplicity of fins (112) is distributed over the outer surface of the enclosure (103).
(FR) L'invention concerne un agencement de haut-parleur comprenant une enceinte thermo-conductrice rigide étanche à l'air (103) comportant une ouverture (115) et une surface externe, et un haut-parleur (101) monté de manière étanche à l'air dans l'ouverture (115) afin de former un volume acoustique verrouillé à l'intérieur de l'enceinte (103). L'agencement comprend en outre une multiplicité d'ailettes thermo-conductrices (112) fixées ou intégrées dans l'enceinte (103) au niveau de la surface externe de celle-ci. La multiplicité d'ailettes (112) est répartie sur la surface extérieure de l'enceinte (103).
