Abstract (en)
[origin: WO2015062852A1] Loudspeaker enclosure comprising at least one loudspeaker having a convex mobile membrane (32A), and a member (12) surrounding the mobile membrane and comprising an external surface (12A) bounded by an internal edge (Γ') situated facing the mobile membrane. The mobile membrane comprises a peripheral edge (Γ) situated facing the internal edge of the member (12) 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%, preferably at least 50%, more preferably still, at least 90%, 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 (PM), and the external surface (12A) of the member has, at the second point, a second tangent plane (P'M). The first tangent plane and the second tangent plane are essentially coincident with one another.
