Abstract

L'invention concerne un dispositif de mise en forme de faisceau acoustique, doté d'au moins deux convertisseurs électrique/acoustique (2a, 2b) situés à une distance physique prédéterminée l'un de l'autre. La mise en phase mutuelle des signaux de sortie des deux convertisseurs est détectée (27) et est multipliée par un facteur constant ou dépendant de la fréquence. En fonction (46, 48) de la mise en phase multipliée et d'au moins un des signaux de sortie des convertisseurs (2a, 2b), un signal de sortie électrique dépendant de la direction d'incidence spatiale des signaux acoustiques par rapport aux convertisseurs, est généré, comme sir les deux convertisseurs étaient situés à une distance virtuelle l'un de l'autre différente et particulièrement supérieure à la distance physique réelle les séparant.
