Abstract
(EN)
Provided in the present application is a sound production device, comprising a housing as well as a vibration system and driving units which are accommodated in the housing. The vibration system comprises a diaphragm, magnetic vibration plates for driving the diaphragm to vibrate, and a transmission member connected to the diaphragm and the magnetic vibration plates; at least two magnetic vibration plates respectively drive different positions of the diaphragm to vibrate; the magnetic vibration plates have one-to-one correspondence to the driving units. The present application can achieve driving force increase, vibration amplitude increase, product sensibility improvement, corresponding range widening, driving fulcrum increase, vibration balance improvement, and product distortion mitigation.

La présente invention concerne un dispositif de production de son, comprenant un boîtier ainsi qu'un système de vibration et des unités d'entraînement qui sont logées dans le boîtier. Le système de vibration comprend une membrane, des plaques magnétiques de vibration pour faire vibrer la membrane et un élément de transmission relié à la membrane et aux plaques magnétiques de vibration; au moins deux plaques magnétiques de vibration entraînent respectivement différentes positions de la membrane à vibrer ; les plaques magnétiques de vibration ont une correspondance univoque avec les unités d'entraînement. La présente invention permet d'obtenir une augmentation de force d'entraînement, une augmentation d'amplitude de vibration, une amélioration de sensibilité de produit, un élargissement de plage correspondant, une augmentation de point d'appui d'entraînement, une amélioration d'équilibre des vibrations et une atténuation de distorsion de produit.
