Beschreibung
Zusammenfassung:	The subject of the present invention is a method for high-power acoustic wave emission and corresponding transducer horns. The technical sector of the invention is that of producing immersed electroacoustic transducers. A transducer horn according to the invention, including at least one driving pillar (column) (1), of cylindrical shape, one end of which is solidly fastened to the said horn (3), is composed of a central core (15), made of rigid material, providing coupling to the end of the said pillar (1), and of an external ring (16) surrounding the said core (15) and made of a material lighter than that of the latter.
