Claims (13)

  1. Enceinte pourvue d'un caisson (10), avec à l'intérieur de ce dernier au moins un transducteur acoustique (38, 40) et une multitude de canaux séparés (42, 44, 46) destinés aux ondes acoustiques générées par la face avant et/ou arrière d'au moins un transducteur acoustique (38, 40) caractérisée en ce que deux transducteurs acoustiques sont prévus, le premier en tant que haut-parleur médium (40) et le second en tant que tweeter (38), et que les canaux (42) en amont du haut-parleur médium (40) présentent un contour qui s'étend jusqu'à la membrane du haut-parleur médium (40) et forme un profil complémentaire à la membrane.
  2. Enceinte selon la revendication 1 caractérisée en ce que le haut-parleur médium (40) est conçu en tant que haut-parleur à cône dynamique.
  3. Enceinte selon la revendication 1 caractérisée en ce que le tweeter (38) est conçu en tant que haut-parleur annulaire à pavillon.
  4. Enceinte selon l'une des revendications 1 à 3 caractérisée en ce qu'un transducteur acoustique (38, 40), au moins, est disposé derrière la paroi avant (12) du caisson (10) qui présente une multitude d'orifices de passage du son (42).
  5. Enceinte selon la revendication 4 caractérisée en ce que les orifices de passage du son (42) forment les canaux et présentent respectivement une largeur qui est inférieure à la moitié de la longueur d'onde de la fréquence la plus haute générée par au moins l'un des transducteurs acoustiques (38, 40).
  6. Enceinte selon la revendication 4 ou 5 caractérisée en ce que les canaux (42) s'étendent pour l'essentiel perpendiculairement au plan de la paroi avant (12) et forment des orifices oblongs s'élargissant de manière conique en direction de la face arrière de la paroi avant.
  7. Enceinte selon l'une des revendications 4 à 6 caractérisée en ce que le caisson (10) présente un orifice bass-reflex (44), disposé de préférence dans la paroi avant (12), qui communique avec la face arrière de l'un des transducteurs acoustiques (40) par le biais d'un système de canaux bass-reflex (46) séparés les uns des autres.
  8. Enceinte selon la revendication 7 caractérisée en ce que les canaux bass-reflex (46) présentent une section transversale dont la longueur la plus grande est inférieure à la moitié de la longueur d'onde de la fréquence la plus haute du transducteur acoustique (40) communiquant avec l'orifice bass-reflex (44).
  9. Enceinte selon la revendication 7 ou 8 caractérisée en ce que le plus petit rayon d'un changement de direction des canaux bass-reflex (46) correspond à la plus petite variation de longueur de leur section transversale.
  10. Enceinte selon l'une des revendications 7 à 9 caractérisée en ce que le système bass-reflex formé par l'orifice bass-reflex (44) et les canaux bass-reflex (46) est réglé sur une fréquence centrale située entre 80 Hz et 120 Hz.
  11. Enceinte selon l'une des revendications 1 à 10 caractérisée en ce que le caisson (10) est composé de plusieurs pièces moulées (12 - 34) en forme de plaques.
  12. Enceinte selon la revendication 11 caractérisée en ce que les pièces moulées (12 - 34) sont des pièces métalliques, de préférence en alliage d'aluminium, fraisées ou moulées et finies par fraisage, ou bien des pièces fabriquées par un procédé d'impression 3D, les pièces moulées (12 - 34) étant.assemblées les unes aux autres par vissage, collage ou soudage.
  13. Enceinte selon l'une des revendications 5 à 12 caractérisée en ce que le haut-parleur médium (40) est orienté de 0,5° à 5°, de préférence de 2,5° environ, dans le sens du tweeter (38) à l'intérieur du caisson (10).
