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(biāo)準(zhǔn)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(gè)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(jì)算機(jī)、打印機(jī)、復(fù)印機(jī)、報(bào)警器、電子玩具、汽車電子設(shè)備、電話機(jī)、定時(shí)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(hào)。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(dāng)接通電源后(),多諧振蕩器起振,輸出,阻抗匹配器推動(dòng)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(dòng)膜片及外殼等組成。接通電源后,振蕩器產(chǎn)生的音頻信號(hào)電流通過(guò)電磁線圈,使電磁線圈產(chǎn)生磁場(chǎng)。振動(dòng)膜片在電磁線圈和磁鐵的相互作用下,周期性地振動(dòng)發(fā)聲。 江蘇接觸器AD16系列蜂鳴器公司
