Abstract

Une tête dynamique d'un haut-parleur comprend une membrane ronde et plate (2) fixée dans un boîtier et excitée au moyen d'un élément d'excitation ayant un bord suivant la circonférence de la membrane et fixé au côté arrière de cette dernière. La membrane (2) comprend une matière de remplissage en nid d'abeilles fixée entre deux feuilles de recouvrement et composée de cellules hexahèdres (6) faites de bandes pliées (7). Lesdites bandes (7) comportent des sections (7a) fixées aux sections adjacentes (7a) des bandes avoisinantes (7). La membrane (2) comporte une nervure (16) constituée par un pli à paroi mince situé sur sa surface perpendiculairement aux sections fixes (7a) des bandes avoisinantes (7). Au lieu d'une nervure (16), on peut en prévoir plusieurs situées symétriquement au-delà de la partie centrale de ladite membrane (2).
