An auxiliary bass radiator unit is disclosed for mounting in an aperture in a loudspeaker enclosure. The unit comprises a substantially rigid panel member (10) mounted on a flexible surround member (12) so as to allow the panel member, when mounted, in use, in the said aperture to move in sympathy with sound waves within the enclosure. The flexible surround member includes a hinge portion (14) mounting the panel member for movement as a hinged flap. By that means movement of the panel member in twisting and other undesirable modes is substantially avoided.
L'invention porte sur un émetteur auxiliaire de basses se montant dans une ouverture pratiquée dans l'enceinte d'un haut-parleur. Ledit émetteur comprend un panneau sensiblement rigide (10) monté sur un élément souple l'entourant (12) de manière à permettre au panneau de vibrer en sympathie avec les ondes sonores de l'intérieur de l'enceinte. L'élément souple comprend une charnière (14) telle que le panneau se comporte comme un volet articulé, ce qui élimine quasiment les mouvements du panneau en torsion et autres modes non souhaitables.
