    电路图箭头朝里：PNP单极管；箭头朝外：NPN的单极管小圆圈为插针。用一根杜邦线将插针与单片机引脚相连，单片机引脚输出低电平，单极管导通，e、c连通，形成回路，有源蜂鸣器发声；无源蜂鸣器需要（与蜂鸣器种类有关，实际使用时可测试）的音频信号，即产生一个不断的高低电平变化，高低电平变化频率为3、单片机I/O口驱动能力非常微弱，不可以通过单片机I/O口直接驱动蜂鸣器，必须通过外接驱动电路，使R39电阻，单极管和R19电阻构成电流的放大电路从而可以驱动蜂鸣器，而不是依靠单片机管脚驱动蜂鸣器4、占空比：高电平时间方波：高电平、低电平时间相同~：取反符号，将管脚输出电平状态取反含有上拉电阻，默认输出高电平。高低电平各延时一段时间。江苏配电箱AD16系列蜂鸣器哪家强
