    本發明涉及家電聲音處理領域，尤其涉及一種蜂鳴器驅動電路。背景技術：現在蜂鳴器家電領域和工控領域的應用越來越，小到用作簡單家電的提示音蜂鳴，大到中央空調的提示音樂，蜂鳴器作為一種人機交互的重要信息傳遞元器件，在相當一段時間內必當占據重要地位。目前，蜂鳴器的驅動方案主要是采用mcu直接輸出pwm方波來驅動，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試。2.采用pwm方波驅動的蜂鳴器產生的聲音音色單一、音調尖銳、音質差。3.在有限且固定的供電電壓的情況下，采用直接pwm波驅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。技術實現要素：本發明所要解決的技術問題在于提供一種蜂鳴器驅動電路，該蜂鳴器驅動電路能夠節省mcu資源以及改善蜂鳴器音質。為解決上述技術問題，本發明采用如下所述的技術方案：一種蜂鳴器驅動電路，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生正弦波信號和第二正弦波信號。
