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)。
