       蜂鳴器：外形：無(wú)源蜂鳴器（外殼有“+”號(hào)，背面為綠色電路板）有源蜂鳴器（無(wú)電路板而用黑膠封閉）源為電源，或者振蕩電路內(nèi)部結(jié)構(gòu)及驅(qū)動(dòng)發(fā)聲方式：電磁式蜂鳴器：由振蕩器、電磁線圈、磁鐵、震動(dòng)膜片、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)膜片在在電磁線圈和磁鐵的相互作用下，周期性振動(dòng)發(fā)聲。屬于有源蜂鳴器壓電式蜂鳴：由多諧振蕩器、壓電蜂鳴器片、阻抗匹配器及共鳴箱、外殼等組成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，輸出的音頻信號(hào)，阻抗匹配器推動(dòng)壓電蜂鳴器發(fā)聲。屬于無(wú)源蜂鳴器用途：提示或報(bào)警自激蜂鳴器是直流電壓進(jìn)行驅(qū)動(dòng)的，不需要利用交流信號(hào)進(jìn)行驅(qū)動(dòng)，只需對(duì)驅(qū)動(dòng)口輸出驅(qū)動(dòng)電平并通過(guò)放大電路（使用單極管放大，單片機(jī)起控制作用）放大驅(qū)動(dòng)電流就能使蜂鳴器發(fā)出聲音。開(kāi)發(fā)板上蜂鳴器為自激蜂鳴器，通常都使用采用直流電壓進(jìn)行驅(qū)動(dòng)的蜂鳴器。2、改變單片機(jī)引腳輸出波形的頻率（即輸入蜂鳴器的波形頻率，即波形周期），就可以調(diào)整蜂鳴器音調(diào)產(chǎn)生各種不同音色、音調(diào)的聲音。改變輸出電平的高低電平占空比，則可以控制蜂鳴器聲音的大?。ǜ唠娖剿紩r(shí)間短，聲音低）。 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。
