Title (EN) SYSTEM FOR REPRODUCING THREE-DIMENSIONAL SOUND FIELD
(FR) SYSTEME SERVANT A REPRODUIRE UN CHAMP SONORE TRIDIMENSIONNEL
Abstract:
(EN) A system for reproducing a three-dimensional sound field includes a signal-processing unit (4), which processes the signals to be sent to small speakers (6L1-6LN, 6R1-6RN) so as to simultaneously correct the characteristics between small speakers (6L1-6LN, 6R1-6RN) and the head of the user (5) and the characteristics between the small speakers (6L1-6LN, 6R1-6RN). The small speakers (6L1-6LN, 6R1-6RN) above the head of the user (5) receive the signals and produce the sounds.
(FR) L'invention concerne un système servant à reproduire un champ sonore tridimensionnel. Le système comprend une unité (4) de traitement de signaux qui traite les signaux destinés à être envoyés vers de petits haut-parleurs (6L1-6LN, 6R1-6RN) de manière à corriger simultanément les caractéristiques entre les petits haut-parleurs (6L1-6LN, 6R1-6RN) et la tête de l'utilisateur (5), ainsi que les caractéristiques entre ces petits haut-parleurs (6L1-6LN, 6R1-6RN). Les petits haut-parleurs (6L1-6LN, 6R1-6RN) situés au-dessus de la tête de l'utilisateur (5) reçoivent les signaux et produisent les sons.
