Abstract
LA PRESENTE INVENTION CONCERNE UN CAISSON ACOUSTIQUE BASSE FREQUENCE. LE CAISSON COMPORTE DEUX ENCEINTES SUPPORTANT AU MOINS UN HAUT-PARLEUR BASSE FREQUENCE, DE MANIERE QUE LA FACE AVANT DE CHAQUE HAUT-PARLEUR RAYONNE A L'INTERIEUR D'UNE CAVITE COMMUNICANT AVEC L'EXTERIEUR PAR UNE OUVERTURE DE DIMENSION PREDETERMINEES. DANS UN MODE PREFERENTIEL DE REALISATION DE L'INVENTION, CES ENCEINTES SONT FACE A FACE DE MANIERE QUE LE HAUT-PARLEUR DE L'UNE SOIT FACE AU HAUT-PARLEUR DE L'AUTRE. UN TEL CAISSON BASSE FREQUENCE EST UTILISE NOTAMMENT DANS LES SYSTEMES DE REPRODUCTION ACOUSTIQUE TRIPHONIQUES HAUTE FIDELITE.
