同时能够对上盖1起到一个保护的效果,防止在安装时对上盖1造成损坏。上盖1的顶部开设有发声孔12,发声孔12与上盖1同轴,这样可以提高蜂鸣器的发声效果。电磁线圈26包括进线端和出线端,其中,进线端和出线端分别位于铁芯25上相对的两侧,这样可以使得在将电磁线圈26绕设在铁芯25上后,能够方便地将余线剪切。综上所述,本实用新型微小型电磁式发生器,其整体几何形状呈立方体状,长宽高分别为3mm、3mm和2mm,尺寸小,能够适用于更精密、体积更小的电子设备。同时发声效果好,固定牢固,密封性强。金属材质的上盖1和下盖2具有耐高温、耐腐蚀、不易变形等有益效果,设置在铜圈28内的振动膜片29能够起到阻挡密封胶和助焊剂渗入到蜂鸣器内部的作用,避免因密封胶或助焊剂渗入到蜂鸣器内部而影响发音效果,稳定性高。后应说明的是:以上所述为本实用新型的推荐实例而已,并不用于限制本实用新型,尽管参照前述实施例对本实用新型进行了详细的说明,对于本领域的技术人员来说,其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换。凡在本实用新型的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
蜂鸣器原主板的故障主要是与Qss和Q54的②、③脚间相连的元件或电路击穿短路或漏电造成。将接于原主板上的电源、内存条和CPU移接到新主板上,通电试机,电源风扇和CPU风扇旋转,蜂鸣器发出清脆的自检声,说明CPU完好。断电测CPU周围的C609~C612、C615~C617的正反向电阻仍然都是5Ω。接好光驱和硬盘的数据线,通电试机,电脑在启动的过程中出现蓝屏,用金海硕大容量硬盘检测修复工具检测硬盘时,弹出“没有发现硬盘”。将硬盘移接到正常工作的惠普电脑上,通电试机,电脑正常启动,硬盘中的所有软件均能快捷准确地执行操作者的指令,将惠普电脑上的好硬盘移接到新换的DELL电脑主板上,通电试机,依然蓝屏,主板是新的,硬盘是好的,只能说明硬盘接口电路或BIOS设置有问题。互换硬盘和光驱接口,能快捷准确地从光盘中读取数据。说明硬盘接口电路完好,只能在BIOS的有关硬盘设置项中寻找解决问题的突破口。如果给预直流信号蜂鸣器是不响应的,因为磁路恒定,钼片不能振动发音。
