    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。无源蜂鸣器工作的理想信号方波。金山区制造AD16系列蜂鸣器费用是多少

    结构原理蜂鸣器1.压电式蜂鸣器压电式蜂鸣器主要由多谐振荡器、压电蜂鸣片、阻抗匹配器及共鸣箱、外壳等组成。有的压电式蜂鸣器外壳上还装有发光二极管。多谐振荡器由晶体管或集成电路构成。当接通电源后(),多谐振荡器起振,输出，阻抗匹配器推动压电蜂鸣片发声。蜂鸣器压电蜂鸣片由锆钛酸铅或铌镁酸铅压电陶瓷材料制成。在陶瓷片的两面镀上银电极，经极化和老化处理后，再与黄铜片或不锈钢片粘在一起。2.电磁式蜂鸣器电磁式蜂鸣器由振荡器、电磁线圈、磁铁、振动膜片及外壳等组成。接通电源后，振荡器产生的音频信号电流通过电磁线圈，使电磁线圈产生磁场。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。 AD16 系列蜂鸣器是工业领域常用的声光报警元件，设备异常时能发出清晰提示音提醒人员。
