Abstract

L'invention concerne les haut-parleurs. Les radiateurs acoustiques connus présentent une caractéristique directive qui varie fortement en fonction de la fréquence dans la direction horizontale et/ou dans la direction verticale. Le radiateur acoustique suivant l'invention qui est au moins bidirectionnel présente un rapport entre les dimensions des unités de radiateurs d'aiguës et de graves, ainsi que de leur montage d'ensemble grâce auquel, par un choix convenable de la fréquence d'intersection, on peut obtenir une caractéristique directive pratiquement indépendante de la fréquence tant en direction horizontale qu'en direction verticale. Application : reproduction acoustique.
