Claims (5)
- REVENDICATIONS1. Antenne acoustique à montage facilité, 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.
- 2. Antenne selon la revendication 1, caractérisée en ce que les transducteurs élémentaires sont de l'un des types électro-acoustiques suivants : piézo-électrique ou électrostrictif.
- 3. Antenne selon la revendication 1 ou 2, caractérisée en ce que la masse de chaque élément de chaque transducteur est optimisée de façon à ramener le point nodal de vibration de la structure au niveau du circuit imprimé.
- 4. Antenne selon l'une des revendications précédentes, caractérisée en ce que les transducteurs élémentaires sont alignés.
- 5. Antenne selon l'une des revendications 1 à 3, caractérisée en ce que les transducteurs élémentaires ne sont pas alignés, leur disposition sur le circuit imprimé les supportant étant fonction des caractéristiques du faisceau acoustique à obtenir.25
