    蜂鸣器驱动电路存在压差，有了振荡的条件，振荡回路30在振荡控制电路20开始振荡驱动蜂鸣器发声。当整个蜂鸣器驱动电路工作时，振荡回路30根据电感l1、第二电感l2和电容c1的参数产生对应的振荡频率，而电感l1、第二电感l2的波形变化引起了振荡控制回路20中的第三电感l3的波形同步变化，第三电感l3伴随产生对应的振荡频率控制第二开关管q2和第三开关管q3的开关状态(导通或截止)，从而精确的锁定振荡回路30的振荡频率并稳定下来，在蜂鸣器两端产生产生标准正弦波，驱动蜂鸣器发声。图3示出了振荡时振荡回路的电容c1、电感l1和第二电感l2的波形，测量时，电容c1以端(与电感l1连接的一端)为正，第二端为负；电感l1以第二端(与电容c1连接的一端)为正，第二端为负；第二电感l2以端(与电源vcc连接的一端)为正，第二端为负。其中，产生于蜂鸣器两端正弦波信号和第二正弦波信号与电感l1和第二电感l2相对应，电容c1的波形由所述正弦波信号和第二正弦波信号叠加而得，电感l1、第二电感l2波形峰值为vcc，电容c1波形峰值为2*vcc(忽略第四电阻r4上的压降后计算得到的一个近似值)。源蜂鸣器没有内部驱动电路，有些公司和工厂称为讯响器，国标中称为声响器。

    本实用新型涉及发声设备技术领域，具体涉及微小型电磁式蜂鸣器。背景技术：目前，市场上的电磁式蜂鸣器小尺寸在**(长*宽*高)，音压在min75db，然而，随着全球科技的日新月异，对产品尺寸的要求日益增多，市场上对电磁式蜂鸣器的要求是尺寸越来越小，音压越来越高，以满足更多的使用需要。技术实现要素：针对现有技术中存在的不足，本实用新型提供了微小型电磁式蜂鸣器，为解决上述技术问题，本实用新型提供的技术方案是：微小型电磁式蜂鸣器，包括同轴的上盖和下盖，上盖呈圆柱体状，下盖呈立方体状，下盖的长度和宽度均为3mm，上盖呈开口朝下的盖体结构并形成有上容纳腔，下盖呈开口朝上的盖体结构并形成有下容纳腔；下容纳腔包括下底端面和下出口端面，下底端面上设置有底板，底板上设置有铁芯，铁芯与下出口端面等高，铁芯外绕设有电磁线圈，电磁线圈外套设有粘磁，粘磁外套设有铜圈，铜圈内还嵌设有振动膜片，振动膜片位于铁芯的上方，铜圈外盖合有上盖，上容纳腔与下容纳腔相接形成有密封的腔室并使上盖和下盖接合，底板、铁芯、电磁线圈、粘磁和铜圈均位于腔室内，并充盈整个腔室；接合后的上盖和下盖整体的几何形状呈立方体状，且高度为2mm。进一步地。蜂鸣器的分类 蜂鸣器主要分为压电式蜂鸣器和电磁式蜂鸣器两种类型。浙江AD16系列蜂鸣器公司
