哪位大神知道扬声器的振幅公式?出自万思迪克斯的一本书 《the loudspeaker design cookbook》(扬声器设计手册)如图,
亚马逊的这本书要卖到50几美金,囊中羞涩啊!

Hello! There is no such thing called '扬声器的振幅公式'.
Would you please specific you question?
Do you want to ask how speaker works?
'The speakers are powered by entering current and voltage:
Electric Power in wires (P) = Voltage difference across the voice coils (v) *Current in coils (i)
**All speakers use amplifiers to add more current to the signal to produce louder sound
**i is a function of time, i(t), whose average value is its maximum amplitude divided by the square root of two.'
