Flow Technology流量計FT-20C1NA-PEA-XX辦事處也就是說，有源蜂鳴器內(nèi)部帶震蕩源，所以只要一通電就會叫。而無源內(nèi)部不帶震蕩源，所以如果用直流信號無法令其鳴叫，必須用2K~5K的方波去驅(qū)動它。有源蜂鳴器往往比無源的貴，就是因為里面多了個震蕩電路。.22蜂鳴器下面我們從EasyARM-i.MX283開發(fā)套件入手，就3.3VNPN三極管驅(qū)動有源蜂鳴器設(shè)計，從實際產(chǎn)品中分析電路設(shè)計存在的問題，提出電路的改進方案，使讀者能從小小的蜂鳴器電路中學(xué)會分析和改進電路的方法，從而設(shè)計出更的產(chǎn)品，達到拋磚引玉的效果。
