An acoustical beam former is proposed with at least two acoustical/electrical converters (2a, 2b) in a predetermined physical distance. The mutual phasing of the output signals of the two converters is detected (27) and is multiplied by a constant or frequency-dependent factor. In dependency (46, 48) from multiplied phasing and from at least one of the output signals of the converters (2a, 2b) there is generated an electric output signal which has a dependency from spatial impinging direction of acoustical signals to the converters (2a, 2b), as if the two converters were located at a virtual distance from each other which is different and especially considerably larger than the real physical distance they are mutually located.

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.
