7.何谓f_0 扬声器的振膜前后振动,就发出声音。振膜的外圈是柔顺的皱折(轭环),其作用相似于弹簧。在某一特定的频率,振膜在较小的驱动力作用下会有较大的振幅,从而扬声器频响上形成一个峰值,该频率就是扬声器共振频率f_0,f_0的大小主要取决于振膜的质量和轭环及定心支片的弹性。对一只扬声器来说,f_0是一个较为重要的指标。由于加在振膜上的驱动力
7. What is f_0 speaker diaphragm vibration before and after the sound. The diaphragm outer ring is a smooth fold (yoke ring), its role is similar to the spring. At a certain frequency, the diaphragm will have a greater amplitude under the action of smaller driving force, so that the speaker frequency response to form a peak, the frequency is the speaker resonant frequency f_0, f_0 depends on the size of the diaphragm Quality and flexibility of yoke ring and centering support. For a speaker, f_0 is a more important indicator. Due to the driving force on the diaphragm
