    本发明涉及一种电磁式蜂鸣器，具体涉及一种高可靠性内置集成电路驱动芯片的有源蜂鸣器。背景技术：现有的电磁式蜂鸣器，大部分仍然使用三极管构成驱动电路的双组电磁线圈结构，由于有双组电磁线圈，存在加工成本高，和容易造成短路等可靠性低的缺点。技术实现要素：本发明的目的是为了解决使用三极管构成驱动电路的双组电磁线圈结构时，成本高、可靠性低的缺点。为了解决所述问题，本发明提供一种高可靠性内置集成电路驱动芯片的蜂鸣器，包括集成电路驱动芯片、电容、单组电磁线圈、线路板、支架、磁环、振动片、正极针脚、负极针脚、壳体、密封胶，其中所述集成电路驱动芯片、电容、正极针脚、负极针脚焊接在线路板上，集成电路驱动芯片电源连接电容的一端，电容的另一端连接负极针脚，集成电路驱动芯片地线端连接负极针脚，单组电磁线圈一端连接正极针脚，单组电磁线圈另一端连接集成电路驱动芯片的输出端，所述集成电路驱动芯片有三个引脚，分别是电源端、地线端、输出端，所述集成电路驱动芯片内部包含振荡电路、二极管、驱动管。为了节约成本，所述集成电路驱动芯片为使用硅材料的集成电路。当蜂鸣器正极针脚接直流电源，当蜂鸣器负极针脚接直流地线时。 奉贤区小型继电器AD16系列蜂鸣器AD16 蜂鸣器壳体选用阻燃工程塑料，符合工业安全标准，使用更可靠。

    这三个晶体管都有被击穿的嫌疑。用热风枪吹下这三个晶体管测量其两个结之间的正反向电阻又符合PN结的单向导电性，击穿漏电现象消失。测这三个晶体管在主板上的焊接脚位②脚和③脚间的正反向电阻仍表现为击穿特征，说明这三个晶体管是完好的，短路问题仍在主板上与这三个晶体管②、③脚相关的其他元件或电路上。测主板上的所有电解电容，发现CPU周围的C609-C612、C615～C617的正反向电阻都为5Ω，试取下CPU时，其正向电阻充电至无穷大，反向电阻为505Ω。用放大镜仔细观察，发现CPU插座内一脚的两个铜触片严重变形，紧紧地绞合在一起，通过放大镜观察，用镊子细心地分离开已经绞合在一起的铜触片，并校正好，安上CPU时，这些电容两极间的正反向电阻又都变为5Ω。是CPU内部击穿了吗？设法购回一个DELL厂原装的同型号新主板，测其电源各输入脚与地间的正反向电阻与坏主板比较，看来问题就出在、电源开关机控制绿线和灰线与地间有元件击穿或漏电。测新板Q55的②脚与③脚间正向电阻为615Ω，反向电阻为672Ω，Q54的②脚与③脚间正向电阻为887Ω，反向电阻为1049Ω，Q52的②脚与③脚间的正向电阻为22Ω，反向电阻为24Ω。
