所謂的蜂鳴器是一種一體化結構的電子訊響器,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,其能發出單調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、復印機、報警器、電子玩具、汽車電子設備、電話機、定時器等電子產品中作發聲器件使用。下面為大家介紹的是蜂鳴器的工作原理及電氣符號。蜂鳴器結構: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光二極管。多諧振蕩器由晶體管或集成電路構成。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,振蕩器產生的音頻信號電流通過電磁線圈,使電磁線圈產生磁場。振動膜片在電磁線圈和磁鐵的相互作用下,周期性地振動發聲。
