单片机综合学习系统之继电器、蜂鸣器篇《电子制作》2007年12月站长原创,如需引用请注明出处9.4蜂鸣器实验在很多的单片机系统中除了显示器件外经常还有发声器件,常见的发声器件是蜂鸣器。蜂鸣器一般用于一些要求不高的声音报警及按键操作提示音等场合。蜂鸣器的形状一般如图9-11所示。虽然它有自己的固有频率,但是它也可以被加以不同频率的方波,从而编制一些简单的音乐。图9-11蜂鸣器实物图9.4.1实例功能本实例就是来实现蜂鸣器发声,通过本小节的实验,可以使读者熟练掌握蜂鸣器的应用。图9-12蜂鸣器实验演示图9.4.2器件和原理蜂鸣器和普通扬声器相比,重要一个特点是只要按照极性要求加上合适的直流电压,就可以发出固有频率的声音,因此使用起来比扬声器简单。由此可知,蜂鸣器的控制和LED的控制对单片机而言是没有区别的。9.4.3硬件电路虽然蜂鸣器的控制和LED的控制对于单片机是一样的,但在硬件电路上却有所不同,因为蜂鸣器是一个感性负载,一般不建议用单片机I/O口直接对它进行操作,所以好加个驱动三极管,在要求较高的场合还会加上反相保护二极管。有的压电式蜂鸣器外壳上还装有发光二极管。浦东新区热继电器AD16系列蜂鸣器厂家
