Abstract

L'invention porte sur un générateur acoustique. Le générateur acoustique comprend un système vibrant qui comprend un diaphragme vibrant et un cylindre à bobine mobile. Une extrémité du cylindre à bobine mobile est combinée de façon fixe au diaphragme vibrant, et est utilisée comme extrémité de sortie avant d'un fil avant du cylindre à bobine mobile ; une partie renforcée est disposée dans la position, sur le diaphragme vibrant, qui correspond à la sortie avant du fil avant ; l'extrémité de sortie avant du fil avant est positionnée en dessous de la partie renforcée ; et la partie renforcée s'étend dans la direction le long du fil du fil avant. Dans la configuration selon la présente invention, du fait que la partie renforcée est disposée au-dessus de la position de sortie avant du fil avant, et que la partie renforcée s'étend vers la direction le long du fil du fil avant, le fil avant est empêché de se courber avec la vibration du diaphragme vibrant quand le fil avant vibre, de façon à faire ainsi vibrer le fil avant en parallèle avec la partie renforcée, à empêcher ainsi le fil avant de générer les défauts de courbure et de rupture du fil, de médiocre conductivité électrique, etc. dans le processus de travail du générateur acoustique, et à assurer la fiabilité du générateur acoustique.
