    电路原理图：蜂鸣器如图1-3所示，使用SH69P43为控制芯片，使用4MHz晶振作为主振荡器。，而。另外在，一个是PWM按键，是用来控制PWM输出口驱动蜂鸣器使用的;另一个是PORT按键，是用来控制I/O口驱动蜂鸣器使用的。连接按键的I/O口开内部上拉电阻。软件设计方法先分析一下蜂鸣器。所使用的蜂鸣器的工作频率是2000Hz，也就是说蜂鸣器的驱动信号波形周期是500μs，由于是1/2duty的信号，所以一个周期内的高电平和低电平的时间宽度都为250μs。软件设计上，我们将根据两种驱动方式来进行说明。 闵行区ABBAD16系列蜂鸣器厂家现货AD16 蜂鸣器采用螺纹螺母紧固，手动即可完成安装，后期维护拆卸便捷。

   蜂鸣器 拔下电源线，用镊子短路三脚插头的两个供电插脚，测另一头三芯插孔的两个供电插孔间的电阻为零，拿开镊子时电阻变为无穷大，说明电源供电线完好，不存在开路和短路故障。测电脑电源各输出脚对地间的电压全部为0V，在紫线与黑线间测不到5V待机电压，绿线与黑线间电压也为0V。拆开电脑电源盒，测电源输入端正反向电阻均为无穷大，测TUBE6A保险丝烧断。测C121两端正向电阻为无穷大，反向电阻为487Ω。C122两端正反向电阻都为13Ω。沿电路找到并联在C121两端的压敏保护电阻RV121(TVR10241X)由黄色变为红色，并被烧缺一块。RV122(TVR10241X)直接被击穿为13Ω，但仍为黄色。测查所有晶体管和大功率管及输出电路的所有整流二极管和滤波电容，对可疑元件逐一拆下检测，未找到击穿、漏电或开路元件。由电路的连接方式可以推断出，TVR10241X的保护电压应该是MYC10K471保护电压的一半。用一个MYG10K471彩电整流滤波输出端的保护压敏电阻，一脚焊接到C121的正极，一脚焊接到C122的负极，将两个串联保护的压敏电阻改为一个，以提高保护的灵敏度和可靠性，更换保险。通电测C121和C122两端的电压分别依次为156V，MYG10K471两端的电压为313V，比彩电中该电阻两端电压298V高5V。
