       蜂鳴器：外形：無源蜂鳴器（外殼有“+”號，背面為綠色電路板）有源蜂鳴器（無電路板而用黑膠封閉）源為電源，或者振蕩電路內(nèi)部結構及驅(qū)動發(fā)聲方式：電磁式蜂鳴器：由振蕩器、電磁線圈、磁鐵、震動膜片、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，振動膜片在在電磁線圈和磁鐵的相互作用下，周期性振動發(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成，當接通電源后（），多諧振蕩器起振，輸出的音頻信號，阻抗匹配器推動壓電蜂鳴器發(fā)聲。屬于無源蜂鳴器用途：提示或報警自激蜂鳴器是直流電壓進行驅(qū)動的，不需要利用交流信號進行驅(qū)動，只需對驅(qū)動口輸出驅(qū)動電平并通過放大電路（使用單極管放大，單片機起控制作用）放大驅(qū)動電流就能使蜂鳴器發(fā)出聲音。開發(fā)板上蜂鳴器為自激蜂鳴器，通常都使用采用直流電壓進行驅(qū)動的蜂鳴器。2、改變單片機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。
