Title
(EN) Sound production device
(ZH) 发声器件
Abstract
(EN) The utility model provides a sounding device. The sounding device comprises a basin frame, the first vibration system comprises a first vibrating diaphragm and a first voice coil which are fixed on the frame; the magnetic circuit system is fixed on the basin stand, a first magnetic gap is formed in one side, close to the first vibrating diaphragm, of the magnetic circuit system, and a second magnetic gap is formed in one side, away from the first vibrating diaphragm; the first voice coil is inserted into the first magnetic gap; the second vibration system comprises a second vibrating diaphragmsupported and fixed on one side, far away from the first vibrating diaphragm, of the magnetic circuit system and a second voice coil, and the second voice coil is inserted in the second magnetic gap;and the flexible circuit board is arranged between the first vibrating diaphragm and the second vibrating diaphragm, and the flexible circuit board is electrically connected with the first voice coiland the second voice coil respectively so as to provide reverse driving signals for the first voice coil and the second voice coil respectively. Compared with the prior art, the sounding device is high in sensitivity and good in user experience effect.
(ZH) 本实用新型提供了一种发声器件,其包括盆架;第一振动系统,包括固定于盆架的第一振膜及第一音圈;磁路系统,固定于盆架,其靠近第一振膜的一侧设有第一磁间隙,远离第一振膜的一侧设有第二磁间隙;第一音圈插设于第一磁间隙内;第二振动系统,包括支撑固定于磁路系统远离第一振膜一侧的第二振膜以及第二音圈,第二音圈插设于第二磁间隙内;柔性电路板,设置于第一振膜与第二振膜之间,述柔性电路板分别与第一音圈及第二音圈电连接,用以为分别为第一音圈和第二音圈提供反向驱动信号。与相关技术相比,本实用新型的发声器件灵敏度高且用户体验效果好。
