Abstract

La présente invention est relative à une antenne acoustique nécessitant le minimum possible d'opérations d'assemblage, ces opérations pouvant être facilement automatisées. L'antenne acoustique conforme à l'invention est caractérisée en ce qu'elle comporte un réseau de transducteurs élémentaires(15), chaque transducteur élémentaire comprenant, entre une contre-masse (10) et un pavillon (9), au moins une céramique (8), tous les transducteurs élémentaires étant montés sur un circuit imprimé (7, 16) commun de liaison électrique entre les transducteurs et de positionnement des transducteurs les uns par rapport aux autres, et au moins un connecteur (26, 27) fixé sur ce circuit imprimé, chacun des transducteurs étant monté de façon que le circuit imprimé soit serré entre sa (ses) céramique(s) et sa contre-masse.
