    蜂鸣器是一种信号提示设备，常常用在电子设备的声音提示中。蜂鸣器采用直流电压供电，其广泛应用于计算机、打印机、复印机、报警器、电子玩具、汽车电子设备、电话机、定时器等电子产品中作发声器件。像日常生活中洗衣机完成洗衣程序后、微波炉完成加热后发出的“嘀...”或“哔...”声都是蜂鸣器产生的。您对蜂鸣器了解有多少？如何挑选高性能蜂鸣器呢？蜂鸣器蜂鸣器根据结构不同分为压电式蜂鸣器和电磁式蜂鸣器；无论是压电式蜂鸣器还是电磁式蜂鸣器，都有有源和无源的区分，其中，“有源”是指蜂鸣器本身内含驱动了，直接给它一定的电压就可以响；“无源”是需要靠外部的驱动才可以响的。一、有源蜂鸣器有源蜂鸣器有源蜂鸣器直接接上额定电源(新的蜂鸣器在标签上都有注明)就可连续发声，有源蜂鸣器工作的理想信号是直流电，通常标示为VDC、VDD等。因为蜂鸣器内部有一简单的振荡电路，能将恒定的直流电转化成一定频率的脉冲信号，从面实出磁场交变，带动钼片振动发音但是在某些有源蜂鸣器在特定的交流信号下也可以工作，只是对交流信号的电压和频率要求很高，此种工作方式一般不采用。有源蜂鸣器：电压，有连续声和断续声两种声音，外壳有一体和分体两种。 线端留下5厘米作引线，用透明胶布把线圈粘好，以免线圈松开再用胶布把它粘在一个盒子上，电磁铁就做好了。
