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交互的重要信息傳遞元器件,在相當一段時間內(nèi)必當占據(jù)重要地位。目前,蜂鳴器的驅(qū)動方案主要是采用mcu直接輸出pwm方波來驅(qū)動,這種方式目前使用較廣,但也有一些無法避免的缺點:1.占用主控mcu資源,使得額外增加蜂鳴器模塊時不利于使用和調(diào)試。2.采用pwm方波驅(qū)動的蜂鳴器產(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)動的蜂鳴器兩端壓差受到供電電壓的限制,進而限制蜂鳴器的音量。技術(shù)實現(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)動電路,該蜂鳴器驅(qū)動電路能夠節(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通或關(guān)斷,當所述電源控制電路導通時,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)生正弦波信號和第二正弦波信號。
