Abstract

Membrane (1) acoustique de forme circulaire présentant une surface supérieure (11) et une surface inférieure (10) opposée, ladite membrane (1) étant destinée à être couplée au niveau de sa surface inférieure (10) à un bobinage mobile (4) via un support (3). La membrane (1) présente un pli annulaire (12) concentrique délimitant dans la membrane (1), une portion centrale (13) circulaire et une portion périphérique annulaire (14). En outre, la portion centrale (13) présente une concavité tournée vers la surface supérieure et l'arête interne (120) du pli (12) est portée par la surface inférieure (10) et comprend une surface d'attache destinée au couplage dudit support (3) de la bobine.
