      蜂鸣器制作工艺：(1)制蜂鸣器备电磁铁M:在长约6厘米的铁螺栓上绕100圈导线,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。(2)制备弹片P:从铁罐头盒上剪下一条宽约2厘米的长铁片，弯成直角，把电磁铁的一条引线接在弹片上，再用胶布把弹片紧贴在木板上。(3)用曲别针做触头Q，用书把曲别针垫高，用胶布粘牢，引出一条导线，如图连接好电路。(4)调节M与P之间的距离(通过移动盒子)，使电磁铁能吸引弹片，调节触点与弹片之间的距离，使它们能恰好接触，通电后就可以听到蜂鸣声。折叠编辑本段分类

蜂鸣器的作用 蜂鸣器是一种一体化结构的电子讯响器。苏州控制箱AD16系列蜂鸣器代理品牌

    将电源(24)脚和④脚排插分别对应插到主板上的插座，通电试机时，电源指示灯时亮时灭，电源风扇和CPU风扇都时转时停，蜂鸣器无通电自检声。测电源各输出脚与地间电压，除紫线与地间电压为稳定的5V，绿线与地间的电压为稳定的，其余各脚与地间的电压都在不停地跳变，说明主板中存在严重的短路故障，拔掉光驱和硬盘的数据线和电源线，通电故障不变。取下CPU和内存条通电，电源风扇时转时停，CPU风扇不转。插入内存条，试短路绿黑线，电源风扇高速旋转，CPU风扇不转，试摸主板各芯片，发现SWSCSOH5514E-NSE0810-A404158S1332860烫手，立即断电。检测数据说明，同一个厂家的不同主板，虽然使用电压相同的电源供电，但其供电脚与地间的正向电阻却相差很多，且供电脚与地间的正反向电阻有时相同，有时相差很大。用测主板各供电脚与地间的正反向电阻查出该主板的短路故障难度很大，只能用测大功率管和各晶体管PN结的正反向电阻来寻求突破。用DT830B数字万用表二极管挡测完主板上的所有晶体管，发现Q55(N790A-EF814)的②脚与③脚间正反向电阻都为4Ω，Q54(N790A-EF814)的②脚与③脚间正反向电阻都为3Ω，Q52(748T40N03G)的②脚与③脚间正向电阻为llΩ，反向电阻为12Ω。 苏州控制箱AD16系列蜂鸣器代理品牌
