哪位大神知道揚(yáng)聲器的振幅公式?出自萬(wàn)思迪克斯的一本書(shū) 《the loudspeaker design cookbook》(揚(yáng)聲器設(shè)計(jì)手冊(cè))如圖, 亞馬遜的這本書(shū)要賣(mài)到50幾美金,囊中羞澀啊! 捕獲.JPG |

Hello! There is no such thing called '揚(yáng)聲器的振幅公式'. 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.' |
