    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。 有“TH”标志的能在湿热带环境下工作。 防护等级：IP20。金山区销售AD16系列蜂鸣器
