    振荡控制电路的第三电感l3的波形以及跟随第三电感l3的波形变化而变化的第二开关管q2、第三开关管q3的波形，其中，第二开关管q2和第三开关管q3的波形为正导通，波形为0截止。由于电感l1的端和第三电感l3的端互为异名端，第二电感l2的端和第三电感l3的端互为同名端，所以第三电感l3的波形与第二电感l2、电感l1同频率，与第二电感l2同相位，与电感l1反相位。当第三电感l3处于正弦波的正半周时，第三开关管q3导通，第二开关管q2截止；当第三电感l3处于正弦波的负半周时，第三开关q3截止，第二开关管q2导通。通过第三电感l3同频率地控制第二开关管q2和第三开关q3的导通和截止，第三电感l3有效的反馈了由电容c1、电感l1和第二电感l2组成的振荡回路，形成了稳定的闭环控制，使工作时的振荡波形稳定。第二开关管q2和第三开关管q3在第三电感l3控制下交替导通与截止，第二开关管q2和第三开关管q3的状态变化，会同频率引起振荡回路的改变。当第三开关管q3导通且第二开关管q2截止时，形成以“第二电感l2和电容c1串联，再与电感l1并联”的振荡回路，如图5所示；当第三开关管q3截止且第二开关管q2导通时，形成以“电感l1和电容c1串联，再与第二电感l2并联”的振荡回路。多谐振荡器由晶体管或集成电路构成。淮安直供AD16系列蜂鸣器性价比
