Abstract

La présente invention concerne un dispositif de haut-parleur. Le dispositif de haut-parleur selon la présente invention comprend : une enceinte de haut-parleur possédant des ouvertures pratiquées dans ses surfaces avant et arrière au niveau de positions opposées entre elles et possédant des ouvertures pratiquées dans ses surfaces latérales gauche et droite au niveau de positions opposées entre elles ; un premier circuit d'attaque de haut-parleur installé au niveau de l'ouverture dans la surface avant de l'enceinte de haut-parleur et tourné vers l'avant ; un second circuit d'attaque de haut-parleur installé au niveau de l'ouverture dans la surface arrière de l'enceinte de haut-parleur et tourné vers l'arrière ; et des premier et second éléments rayonnants passifs installés dans l'ouverture de surface latérale gauche et l'ouverture de surface latérale droite de l'enceinte de haut-parleur de manière latéralement symétrique. Selon la présente invention, un dispositif de haut-parleur peut présenter une structure simple, mais avoir un faible point de résonance tout en étant de petite taille, en raison du poids des éléments rayonnants passifs et peut être formé petit tout en reproduisant une vaste largeur de bande de fréquence.
