奉贤区直供AD16系列蜂鸣器货源充足

     输出一定频率信号经驱动电路由输出端out驱动单组电磁线圈，使得蜂鸣器发出声音，声音的频率由集成电路驱动芯片内部振荡电路的频率而定。因为pmos管对电容充电所产生的压降远小于整流电路对电容充电所产生的压降，如二极管作为整流电路对电容充电所产生的压降约为，而由集成电路驱动芯片内部控制电路控制pmos管对电容充电所产生的压降约为，所以本发明有效降低了蜂鸣器的启动电压，如果所述集成电路驱动芯片不含有电压基准源，启动电压会更低。电容具有稳定集成电路驱动芯片电源电压，以及有效吸收单组电磁线圈所产生的尖峰电压与瞬间大电流的作用，有效的提高了蜂鸣器的可靠性。为了进一步节约成本，所述集成电路驱动芯片为使用硅材料的集成电路。推荐的，所述的集成电路驱动芯片内部pmos管可以使用pnp三极管代替。综上所述，本发明带来的有益效果：一种内置低电压启动驱动芯片的蜂鸣器，具有启动电压低、可靠性高和成本低的优点。附图说明图1是本发明的结构示意图。图2是本发明的电路示意图。具体实施方式为使本发明的目的、技术方案和优点更加清楚，以下结合附图及具体实施例，对本发明作进一步地详细说明。如图1所示，本发明提供一种内置低电压启动驱动芯片的蜂鸣器。压无源蜂鸣属于容性负载器件，理想输入是双向方波通常记作：VP-P。奉贤区直供AD16系列蜂鸣器货源充足
