LOUDSPEAKER ENCLOSURE WITH AT LEAST ONE LOUDSPEAKER WITH A CONVEX MOBILE MEMBRANE EXHIBITING CONTINUITY OF SHAPE WITH AN ADJACENT MEMBER

摘要

Loudspeaker enclosure comprising at least one loudspeaker having a convex mobile membrane, and a member surrounding the mobile membrane and comprising an external surface bounded by an internal edge (Γ′)situated facing the mobile membrane, which comprises a peripheral edge (Γ) situated facing the internal edge of the member and forming a closed loop. The mobile membrane and the member have a suitable shape such that, over a continuous portion (Γ″) of the peripheral edge (Γ) representing at least 25% of the length of the peripheral edge, for any first point (M) on the continuous portion and any second point (M′) situated on the internal edge at a location such that the distance between the first point (M) and second point (M′) is minimal, the mobile membrane has, at the first point, a first tangent plane, essentially coincident with a second tangent plane at the second point.
