蜂鸣器 技术实现要素:本实用新型的主要目的是提出一种便于安装的压电式蜂鸣器,旨在解决现有的压电式蜂鸣器大多装配复杂,安装较为繁琐,效率低,不方便安装及后期维护的技术问题。为实现上述目的,本实用新型提出的便于安装的压电式蜂鸣器,包括壳体、后盖、压电陶瓷片以及插脚,所述壳体呈圆柱体形设置,所述壳体的后端面凹设有一沿长度方向延伸且与所述压电陶瓷片相适配的呈圆环形的共振腔,所述压电陶瓷片可拆卸的嵌设于所述共振腔内设置,所述后盖可拆卸的嵌设于所述共振腔的后端开口处设置,所述插脚平行的凸设于所述后盖的后端面设置,且所述插脚与所述压电陶瓷片电性连接,所述壳体的下端外周壁设有安装板,所述壳体后端面的两侧外周壁分别对称的凸设有第二安装板,所述安装板分别与所述第二安装板垂直连接,所述安装板的两端分别对称的凹设有安装孔,所述第二安装板凹设有第二安装孔。可选地,所述安装板呈矩形设置,且所述安装孔对称平行的设置于所述壳体的外周壁的两侧。可选地,所述安装孔为u型槽,所述u型槽的后端面具有一开口,且所述u型槽沿长度方向延伸。可选地,所述第二安装板的外周壁呈圆弧形设置,所述第二安装孔对称的设置于所述壳体的外周壁的两侧。 电磁式蜂鸣器 电磁式蜂鸣器由振荡器、电磁线圈、磁铁、振动膜片及外壳等组成。
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。 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。普陀区销售AD16系列蜂鸣器性价比
