(JA) 音響装置
Abstract
(EN)
An acoustic device 1 mounted in a vehicle 5 and comprising: two speakers 30, 40 arranged so as to interpose therebetween a center line 11 of a seat 10, further forward than the front of a driver 20 being an occupant sitting in the seat 10; and a control unit 100 that controls the characteristics of sound output from each speaker so as to maintain a stereophonic sound image caused by sound output from the two speakers 30, 40. The two speakers 30, 40 are provided in the steering wheel 8 of the vehicle 5.
(FR)
Un dispositif acoustique 1 monté dans un véhicule 5 comprend : deux haut-parleurs 30, 40 agencés de façon à interposer entre eux une ligne centrale 11 d'un siège 10, plus en avant que l'avant d'un conducteur 20 qui est un occupant assis dans le siège 10; et une unité de commande 100 qui commande les caractéristiques de sortie sonore de chaque haut-parleur de façon à maintenir une image sonore stéréophonique provoquée par la sortie sonore provenant des deux haut-parleurs 30, 40. Les deux haut-parleurs 30, 40 sont prévus dans le volant 8 du véhicule 5.
