突出型壓電式蜂鳴器autonics,TZ4L-R4S,韓國(guó)奧拓尼克斯開(kāi)關(guān)配件,TZ4L-R4C
1．壓電式蜂鳴器 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（1.5~15V直流工作電壓），多諧振蕩器起振，輸出1.5~2.5kHZ的音頻信號(hào)，阻抗匹配器推動(dòng)壓電蜂鳴片發(fā)聲。
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。
