Abstract

Procédé d'émission de forte puissance d'ondes acoustiques et les pavillons de transducteurs correspondant. Le secteur technique de l'invention est celui de la réalisation de transducteurs électroacoustiques immergés. Un pavillon de transducteur suivant l'invention, comportant au moins un pilier moteur (1), de forme cylindrique, dont une extrémité est solidaire dudit pavillon (3), est composé d'un noyau (15) central, en matériau rigide, assurant le couplage avec l'extrémité dudit pilier (1), et d'une couronne externe (16) entourant ledit noyau (15) et réalisée en matériau plus léger que celui-ci.
