    本發(fā)明涉及家電聲音處理領(lǐng)域，尤其涉及一種蜂鳴器驅(qū)動(dòng)電路。背景技術(shù)：現(xiàn)在蜂鳴器家電領(lǐng)域和工控領(lǐng)域的應(yīng)用越來越，小到用作簡單家電的提示音蜂鳴，大到中央空調(diào)的提示音樂，蜂鳴器作為一種人機(jī)交互的重要信息傳遞元器件，在相當(dāng)一段時(shí)間內(nèi)必當(dāng)占據(jù)重要地位。目前，蜂鳴器的驅(qū)動(dòng)方案主要是采用mcu直接輸出pwm方波來驅(qū)動(dòng)，這種方式目前使用較廣，但也有一些無法避免的缺點(diǎn)：1.占用主控mcu資源，使得額外增加蜂鳴器模塊時(shí)不利于使用和調(diào)試。2.采用pwm方波驅(qū)動(dòng)的蜂鳴器產(chǎn)生的聲音音色單一、音調(diào)尖銳、音質(zhì)差。3.在有限且固定的供電電壓的情況下，采用直接pwm波驅(qū)動(dòng)的蜂鳴器兩端壓差受到供電電壓的限制，進(jìn)而限制蜂鳴器的音量。技術(shù)實(shí)現(xiàn)要素：本發(fā)明所要解決的技術(shù)問題在于提供一種蜂鳴器驅(qū)動(dòng)電路，該蜂鳴器驅(qū)動(dòng)電路能夠節(jié)省mcu資源以及改善蜂鳴器音質(zhì)。為解決上述技術(shù)問題，本發(fā)明采用如下所述的技術(shù)方案：一種蜂鳴器驅(qū)動(dòng)電路，其包括有電源控制電路、振蕩控制電路和振蕩回路，所述電源控制電路與mcu連接，mcu輸出高、低電平控制所述電源控制電路導(dǎo)通或關(guān)斷，當(dāng)所述電源控制電路導(dǎo)通時(shí)，所述振蕩控制電路控制所述振蕩回路振蕩并于蜂鳴器兩端產(chǎn)生正弦波信號(hào)和第二正弦波信號(hào)。靜安區(qū)配電箱AD16系列蜂鳴器哪家好
