    所謂的蜂鳴器是一種一體化結(jié)構(gòu)的電子訊響器，在電路中用字母“H”或“HA”（舊標準用“FM”、“LB”、“JD”等）表示。蜂鳴器采用直流電壓供電，其能發(fā)出單調(diào)的或者某個固定頻率的聲音，如嘀嘀嘀，嘟嘟嘟等。蜂鳴器主要分為壓電式蜂鳴器和電磁式蜂鳴器兩種類型，通常在計算機、打印機、復(fù)印機、報警器、電子玩具、汽車電子設(shè)備、電話機、定時器等電子產(chǎn)品中作發(fā)聲器件使用。下面為大家介紹的是蜂鳴器的工作原理及電氣符號。蜂鳴器結(jié)構(gòu)：1．電壓式蜂鳴器壓電式蜂鳴器主要由多諧振蕩器、壓電蜂鳴片、阻抗匹配器及共鳴箱、外殼等組成。有的壓電式蜂鳴器外殼上還裝有發(fā)光二極管。多諧振蕩器由晶體管或集成電路構(gòu)成。當接通電源后（），多諧振蕩器起振，輸出，阻抗匹配器推動壓電蜂鳴片發(fā)聲。蜂鳴器壓電蜂鳴片由鋯鈦酸鉛或鈮鎂酸鉛壓電陶瓷材料制成。在陶瓷片的兩面鍍上銀電極，經(jīng)極化和老化處理后，再與黃銅片或不銹鋼片粘在一起。2．電磁式蜂鳴器電磁式蜂鳴器由振蕩器、電磁線圈、磁鐵、振動膜片及外殼等組成。接通電源后，振蕩器產(chǎn)生的音頻信號電流通過電磁線圈，使電磁線圈產(chǎn)生磁場。振動膜片在電磁線圈和磁鐵的相互作用下，周期性地振動發(fā)聲。
