(FR) DISPOSITIF DE REPRODUCTION AUDIO
(JA) オーディオ再生装置
Abstract
(EN)
An audio reproduction device is provided with: first and second speaker support bodies which are provided on a case in a freely openable and closable manner and each have a cover shape; a sensor which detects a first state in which the first and second speaker support bodies are closed, and a second state in which the first and second speaker support bodies are opened and substantially horizontally held; first and second speakers which are respectively attached on the front surfaces of the first and second speaker support bodies so as to have a larger distance therebetween in the second state than that in the first state; and a reproduction characteristic control unit which switches reproduction characteristics of the first and second speakers between the first state and the second state by the detection signal of the sensor.
(FR)
La présente invention concerne un dispositif de reproduction audio comprenant : des premier et second corps de support de haut-parleur qui sont disposés sur un boîtier d'une manière pouvant s'ouvrir et se fermer librement et ont chacun une forme de couvercle; un capteur qui détecte un premier état dans lequel les premier et second corps de support de haut-parleur sont fermés, et un second état dans lequel les premier et second corps de support de haut-parleur sont ouverts et maintenus sensiblement horizontalement; des premier et second haut-parleurs qui sont respectivement fixés sur les surfaces avant des premier et second corps de support de haut-parleur de façon à avoir une plus grande distance entre eux dans le second état que celui dans le premier état; et une unité de commande de caractéristique de reproduction qui commute les caractéristiques de reproduction des premier et second haut-parleurs entre le premier état et le second état par le signal de détection du capteur.
(JA)
ケースに対して開閉自在に設けられた蓋状の第1及び第2のスピーカ支持体と、第1及び第2のスピーカ支持体が閉じている第1状態と、第1及び第2のスピーカ支持体が開いてほぼ水平に保持されている第2状態を検出するセンサーと、第1状態に比して第2状態の間隔がより広いものとなるように、第1及び第2のスピーカ支持体の前面に対してそれぞれ取り付けられた第1及び第2のスピーカと、センサーの検出信号によって、第1状態と第2状態とで、第1及び第2のスピーカの再生特性を切り替える再生特性制御部とを備えるオーディオ再生装置である。
