L'invention concerne un système de vibration dans une unité sonore et un dispositif sonore, comprenant une ligne d'extension de conducteur (3) reliée électriquement à un conducteur de bobine acoustique. La ligne d'extension de conducteur (3) s'étend à partir d'une position de celle-ci qui est électriquement reliée à la bobine acoustique, le long de la direction de paroi latérale d'une bobine acoustique (1), et la ligne d'extension de conducteur (3) est pourvue d'une partie courbe (30) qui se courbe vers la direction de vibration de la bobine acoustique (1). La déformation de la partie courbe (30) peut être dispersée dans toute la ligne d'extension de conducteur (3), et la contrainte et la déformation de la ligne d'extension de conducteur (3) pendant le processus de vibration peut être efficacement dispersée et réduite, de manière à éviter un problème avec la fiabilité de la ligne d'extension de conducteur (3) en raison de la rupture de celle-ci.
