Abstract
L’invention concerne un mobilier (10) à diffusion acoustique corrigée comprenant : - un corps (12) comprenant une paroi (18) formant une cavité de réception (20), - un dispositif d’excitation acoustique (24) disposé à l’intérieur de la cavité de réception et couplé à ladite paroi, ledit dispositif d’excitation acoustique étant configuré pour faire vibrer ladite paroi à partir d’un signal audio et utiliser ladite cavité de réception comme caisse de résonance pour générer un son hors du corps à partir de l’excitation de ladite paroi, et - un dispositif de correction acoustique physique (32) et/ou logicielle (66) pour contrôler la génération du son issu de l’excitation de ladite paroi de manière à produire une trame acoustique corrigée. Figure pour l’abrégé : Fig. 1
