蜂鸣器是一种能够发出类似蜂鸣声音的电声元器件,常用来代替电铃或作声频电流发生器。汽车蜂鸣器是什么?汽车蜂鸣器包括多方面的,其实汽车蜂鸣器就是使用在汽车上面的蜂鸣器,比如倒车雷达提示,安全带未系提示,门未关好提示等。而蜂鸣器的主要作用是,如果车上人员未按规定系好安全带(一般只在主副驾驶位上装有蜂鸣器),安全带警告灯和蜂鸣器提示装置就会发出警告车上人员,提示人员系好安全带,不然只要车辆一行驶它就响个不停,让你没办法忽视它的存在,而这对于提高我们的安全意识非常有帮助。关于此方面的专项研究结果显示,安全带提醒装置将安全带的佩戴率大约提高了41%,已挽救了很多驾驶及车上人员的生命。另外用于倒车雷达的蜂鸣器,当汽车倒车时,前后左右都会提醒驾驶员危险距离,当倒车时后方遇到障碍物时就会发出连续报警,提示当前不能继续倒车,继续倒的话将会遇到障碍物,当然这对于车主而言也是非常有用的。汽车上用到的蜂鸣器非常之多,压电式、电磁式、贴片式、有源和无源全方面涉及,建议汽车蜂鸣器坏了或出现毛病时,也不要随意选购,应选择4S店或咨询正规蜂鸣器厂商,避免选择错误影响使用。节点支持方式-将蜂鸣片固定于约与陶瓷片直径同尺寸的环形结构内。淮安热继电器AD16系列蜂鸣器厂家

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。PCB固定式压电无源 弹簧针式压电无源蜂鸣器。长宁区控制箱AD16系列蜂鸣器货源充足
