    结构原理蜂鸣器1.压电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。 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，再与黄铜片或不锈钢片粘在一起。闵行区制造AD16系列蜂鸣器厂家直销

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。闵行区制造AD16系列蜂鸣器厂家直销
