    蜂鳴器驅(qū)動(dòng)電路存在壓差，有了振蕩的條件，振蕩回路30在振蕩控制電路20開始振蕩驅(qū)動(dòng)蜂鳴器發(fā)聲。當(dāng)整個(gè)蜂鳴器驅(qū)動(dòng)電路工作時(shí)，振蕩回路30根據(jù)電感l(wèi)1、第二電感l(wèi)2和電容c1的參數(shù)產(chǎn)生對(duì)應(yīng)的振蕩頻率，而電感l(wèi)1、第二電感l(wèi)2的波形變化引起了振蕩控制回路20中的第三電感l(wèi)3的波形同步變化，第三電感l(wèi)3伴隨產(chǎn)生對(duì)應(yīng)的振蕩頻率控制第二開關(guān)管q2和第三開關(guān)管q3的開關(guān)狀態(tài)(導(dǎo)通或截止)，從而精確的鎖定振蕩回路30的振蕩頻率并穩(wěn)定下來，在蜂鳴器兩端產(chǎn)生產(chǎn)生標(biāo)準(zhǔn)正弦波，驅(qū)動(dòng)蜂鳴器發(fā)聲。圖3示出了振蕩時(shí)振蕩回路的電容c1、電感l(wèi)1和第二電感l(wèi)2的波形，測(cè)量時(shí)，電容c1以端(與電感l(wèi)1連接的一端)為正，第二端為負(fù)；電感l(wèi)1以第二端(與電容c1連接的一端)為正，第二端為負(fù)；第二電感l(wèi)2以端(與電源vcc連接的一端)為正，第二端為負(fù)。其中，產(chǎn)生于蜂鳴器兩端正弦波信號(hào)和第二正弦波信號(hào)與電感l(wèi)1和第二電感l(wèi)2相對(duì)應(yīng)，電容c1的波形由所述正弦波信號(hào)和第二正弦波信號(hào)疊加而得，電感l(wèi)1、第二電感l(wèi)2波形峰值為vcc，電容c1波形峰值為2*vcc(忽略第四電阻r4上的壓降后計(jì)算得到的一個(gè)近似值)。浙江主營(yíng)AD16系列蜂鳴器推薦廠家常規(guī)電磁蜂鳴器產(chǎn)品是如何工作的？
