Abstract

Dispositif acoustique comportant une structure comprenant une surface (1) apte à être mise en vibration en au moins une zone contrôlée de sorte à émettre un son, et des actionneurs(A1, A2, A3, A4, A5) aptes à provoquer une déformation à la surface au niveau de zones contrôlées (Z1, Z2, Z3, Z4, Z5) de sorte à la mettre en vibration, des moyens de contrôle (6) des actionneurs (A1, A2, A3, A4, A5) configurés pour envoyer des signaux de contrôle audits actionneurs (A1, A2, A3, A4, A5), comprenant des moyens de calcul (8) desdits signaux de contrôle, lesdits moyens de calcul mettant en œuvre une opération de filtrage inverse, de sorte à émettre, à partir d’un son à générer, des signaux de contrôle audits actionneurs (A1, A2, A3, A4, A5), de sorte à mettre au moins une partie des zones contrôlées (Z1, Z2, Z3, , Z5) en vibration et à émettre le son donné, et compensant au moins partiellement la distorsion, la réverbération et la propagation des ondes. Figure pour l’abrégé : 1A.Acoustic device comprising a structure comprising a surface (1) capable of being vibrated in at least one controlled zone so as to emit a sound, and actuators (A1, A2, A3, A4, A5) capable of causing a deformation to the surface at the level of controlled zones (Z1, Z2, Z3, Z4, Z5) so as to make it vibrate, control means (6) of the actuators (A1, A2, A3, A4, A5) configured to send control signals to said actuators (A1, A2, A3, A4, A5), comprising calculation means (8) of said control signals, said calculation means implementing an inverse filtering operation, so as to emit, from of a sound to be generated, control signals to said actuators (A1, A2, A3, A4, A5), so as to put at least part of the controlled zones (Z1, Z2, Z3, , Z5) in vibration and to emit the given sound, and at least partially compensating for distortion, reverberation and wave propagation. Figure for abstract: 1A.
