摘要
分析了膜片加强筋的筋脉、剖面形状、面形状、角度等对扬声器低频参数的影响,得出了加强筋与膜片等效顺性以及有效振动面积之间的关系。从而为膜片的设计及改善指明了明确的方向。
Through the effect of strengthening rib for diaphragm of rib veins,section shape,surface shape and angle etc. on the low-frequency parameters of speaker is analyzed,draws the affecting relation of strengthening rib and equivalent compliance,effective vibration area of diaphragm.Finally points out a clear direction to design and improve diaphragm.
