淮安主营AD16系列蜂鸣器哪家强

    所谓的蜂鸣器是一种一体化结构的电子讯响器，在电路中用字母“H”或“HA”（旧标准用“FM”、“LB”、“JD”等）表示。蜂鸣器采用直流电压供电，其能发出单调的或者某个固定频率的声音，如嘀嘀嘀，嘟嘟嘟等。蜂鸣器主要分为压电式蜂鸣器和电磁式蜂鸣器两种类型，通常在计算机、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使用。下面为大家介绍的是蜂鸣器的工作原理及电气符号。蜂鸣器结构：1．电压式蜂鸣器压电式蜂鸣器主要由多谐振荡器、压电蜂鸣片、阻抗匹配器及共鸣箱、外壳等组成。有的压电式蜂鸣器外壳上还装有发光二极管。多谐振荡器由晶体管或集成电路构成。当接通电源后（），多谐振荡器起振，输出，阻抗匹配器推动压电蜂鸣片发声。蜂鸣器压电蜂鸣片由锆钛酸铅或铌镁酸铅压电陶瓷材料制成。在陶瓷片的两面镀上银电极，经极化和老化处理后，再与黄铜片或不锈钢片粘在一起。2．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。接通电源后，振荡器产生的音频信号电流通过电磁线圈，使电磁线圈产生磁场。振动膜片在电磁线圈和磁铁的相互作用下，周期性地振动发声。 振动膜片在电磁线圈和磁铁的相互作用下，周期性地振动发声。淮安主营AD16系列蜂鸣器哪家强
