    蜂鸣器驱动电路存在压差，有了振荡的条件，振荡回路30在振荡控制电路20开始振荡驱动蜂鸣器发声。当整个蜂鸣器驱动电路工作时，振荡回路30根据电感l1、第二电感l2和电容c1的参数产生对应的振荡频率，而电感l1、第二电感l2的波形变化引起了振荡控制回路20中的第三电感l3的波形同步变化，第三电感l3伴随产生对应的振荡频率控制第二开关管q2和第三开关管q3的开关状态(导通或截止)，从而精确的锁定振荡回路30的振荡频率并稳定下来，在蜂鸣器两端产生产生标准正弦波，驱动蜂鸣器发声。图3示出了振荡时振荡回路的电容c1、电感l1和第二电感l2的波形，测量时，电容c1以端(与电感l1连接的一端)为正，第二端为负；电感l1以第二端(与电容c1连接的一端)为正，第二端为负；第二电感l2以端(与电源vcc连接的一端)为正，第二端为负。其中，产生于蜂鸣器两端正弦波信号和第二正弦波信号与电感l1和第二电感l2相对应，电容c1的波形由所述正弦波信号和第二正弦波信号叠加而得，电感l1、第二电感l2波形峰值为vcc，电容c1波形峰值为2*vcc(忽略第四电阻r4上的压降后计算得到的一个近似值)。振动膜片在电磁线圈和磁铁的相互作用下，周期性地振动发声。虹口区主营AD16系列蜂鸣器厂家现货
