Abstract
(EN)
The present invention provides a sound production device, comprising a housing and a vibration assembly. The vibration assembly comprises a vibration diaphragm and a voice coil combined to one side of the vibration diaphragm. The sound production device further comprises a system stabilization component; the system stabilization component is connected to the voice coil; the system stabilization component is a linear structure and formed by winding a metal wire, and comprises a first connection part connected to the voice coil, a deformation part, and a second connection part connected to the housing. By means of the sound production device having this structure, the voice coil is not polarized under the condition of large displacement, and the system stabilization component having a novel structure does not block the free vibration of the voice coil, either.

La présente invention concerne un dispositif de production de sons, comprenant un boîtier et un ensemble de vibration. Le système de vibration comprend une membrane de vibration et une bobine acoustique combinée à un coté de la membrane de vibration. Le dispositif de production de son comprend en outre un composant de stabilisation de système ; le composant de stabilisation de système est connecté à la bobine acoustique ; le composant de stabilisation de système est une structure linéaire et est formé par enroulement d'un fil métallique, et comprend une première partie de raccordement reliée à la bobine acoustique, une partie de déformation et une seconde partie de raccordement reliée au boîtier. Au moyen du dispositif de production de son ayant cette structure, la bobine acoustique n'est pas polarisée sous l'effet d'un déplacement important, et le composant de stabilisation de système ayant une nouvelle structure ne bloque pas non plus la vibration libre de la bobine acoustique.
