Abstract

Le haut-parleur (10) électrodynamique comportant : - un châssis fixe (12), - un moteur comportant une base fixe (14) reliée au châssis fixe (12) et un équipage mobile (16) axialement par rapport à la base fixe (14) suivant un axe (A-A'), - une membrane convexe (18) dont la convexité est orientée vers l'extérieur du haut-parleur (10), et - un treillis (20) reliant la membrane convexe (18) et l'équipage mobile (16). Le treillis (20) comprend un anneau interne (46) et un anneau externe (48) coaxiaux reliés ensemble par des piliers radiaux (50) et à une couronne (52) de fixation à une extrémité (53) de l'équipage mobile (16), la membrane convexe (18) étant fixée en appui sur les anneaux interne et externe (46, 48).
