Abstract

L'invention concerne un dispositif (1) de diffusion sonore comprenant une section haute fréquence (2), et une section moyenne fréquence (3, 4) comportant au moins deux sources acoustiques moyenne fréquence (SMF), superposées verticalement, où la section moyenne fréquence (3, 4) comprend une sous-section inférieure (3) disposée en-dessous de la section haute fréquence (2) et comprenant au moins une source acoustique moyenne fréquence (SMF) et une sous-section supérieure (4) disposée au-dessus de la section haute fréquence (2) et comprenant au moins une source acoustique moyenne fréquence (SMF), où la directivité verticale de la section haute fréquence (2) présente une inclinaison, relativement à l'horizontale (H), sensiblement égale à l'inclinaison (θMF) de la directivité verticale de la section moyenne fréquence (3, 4) relativement à l'horizontale (H). L'invention permet d'optimiser l'augmentation du niveau de pression sonore et de la portée, tout en conservant un niveau d'intelligibilité élevé.
