Abstract
The invention relates to an electro-acoustic to enclosure (10) comprising walls defining two cavities (1; 2), each provided with an aperture (11; 21) shut off by a loudspeaker (12; 22), noteworthy in that it is said to be “enclosed” and in that each cavity (1; 2) has a shape for which the intersection with any plane containing the central axis (X1-X1′; X2, X2′) of said loudspeaker (12; 22) is a portion of an ellipse (E1i; E2i), the major axes (X1i-X1i′; X2i-X2i′) of said ellipses (E1i; E2i) being substantially coincident with said central axis (X1-X1′; X2, X2′) of said loudspeaker (12; 22), said aperture (11; 21) being secant to said ellipses (E1i; E2i) in such a way that the second extreme points (P1i′; P2i′) of each ellipse (E1i; E2i) are situated in said aperture (11; 21).
