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。
折叠编辑本段简介压电式蜂鸣器是一种电声转换器件。将压电材料粘贴在金属片上,当压电材料和金属片两端施加上一个电压后,因为压电效应,蜂鸣片就会产生机械变形而发出声响。压电材料有多种,用在蜂鸣片上的压电材料通常是高压极化后的压电陶瓷片。折叠编辑本段外观结构压电式蜂鸣器通常呈圆形,由压电陶瓷片、引线和共鸣腔组成。而中间的压电陶瓷片又由金属镀层、陶瓷片、胶水、金属片构成。常见的压电式蜂鸣器的形状及电路符号如右图所示:从电学角度来看,压电陶瓷可以简化为一个电感和一个电容的串联模型。折叠编辑本段分类除上图所示的两根电极的全电极型压电蜂鸣片之外,还有一种三个电极的反馈电极型压电蜂鸣片。通常全电极型蜂鸣片驱动电路简单,但发出的声音较小;反馈电极型驱动电路相对复杂,但发出的声音较大。以回授方式区分,压电式蜂鸣器大致分为回授式蜂鸣片(自激式)与无回授式蜂鸣片(外激式)两种。当回授式蜂鸣片搭配正回授振荡电路会产生一个与共振腔频率相同的单音;而无回授式蜂鸣片则可以搭配外部振荡电路,选择任意频率发出声音。折叠编辑本段特点及应用压电式蜂鸣器具有体积小、灵敏度高、耗电省、可靠性好,造价低廉的特点和良好的频率特性。发声形式:连续、断续 接线方式为接插式; 头部有:圆形,方形,矩形。
