Title
(EN) Vibrating diaphragm and sounding device using same
(ZH) 振膜和应用该振膜的发声装置
Abstract
(EN) The utility model provides a vibrating diaphragm and a sounding device using the same, which comprise a vibrating diaphragm body part and a composite layer combined at the central position of the vibrating diaphragm body part, and are characterized in that the composite layer comprises a porous material layer, and a first metal layer and a second metal layer which are respectively arranged at twosides of the porous material layer. Compared with the prior art, the composite layer of the vibrating diaphragm adopts a composite structure of the porous material layer and the metal layer, the massof the vibrating diaphragm can be reduced while the vibration rigidity is ensured, the modulus density ratio of the vibrating diaphragm is improved, and meanwhile, the porous structure material can increase the damping of the vibrating diaphragm, absorb the vibration energy under the specific resonance frequency and effectively improve the high-frequency segmentation vibration; distortion is reduced, and high-pitch tone quality is improved.
(ZH) 本实用新型提供了一种振膜和应用该振膜的发声装置,包括振膜本体部和结合于所述振膜本体部中心位置上的复合层,其特征在于,所述复合层包括多孔材料层和分别设置于所述多孔材料层两侧的第一金属层和第二金属层。与相关技术相比,振膜的复合层采用多孔材料层和金属层复合的结构,可以保证振动刚性的同时减小振膜的质量,提高振膜的模量密度比,同时多孔结构材料可以增大振膜的阻尼,吸收特定谐振频率下的振动的能量,有效改善高频分割振动,减小失真,提升高音音质。
