    驅(qū)動方式蜂鳴器由于自激蜂鳴器是直流電壓驅(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)動電平并通過三極管放大驅(qū)動電流就能使蜂鳴器發(fā)出聲音，很簡單，這里就不對自激蜂鳴器進行說明了。這里只對必須用1/2duty的方波信號進行驅(qū)動的他激蜂鳴器進行說明。單片機驅(qū)動他激蜂鳴器的方式有兩種:一種是PWM輸出口直接驅(qū)動，另一種是利用I/O定時翻轉(zhuǎn)電平產(chǎn)生驅(qū)動波形對蜂鳴器進行驅(qū)動。PWM輸出口直接驅(qū)動是利用PWM輸出口本身可以輸出一定的方波來直接驅(qū)動蜂鳴器。在單片機的軟件設(shè)置中有幾個系統(tǒng)寄存器是用來設(shè)置PWM口的輸出的，可以設(shè)置占空比、周期等等，通過設(shè)置這些寄存器產(chǎn)生符合蜂鳴器要求的頻率的波形之后，只要打開PWM輸出，PWM輸出口就能輸出該頻率的方波，這個時候利用這個波形就可以驅(qū)動蜂鳴器了。比如頻率為2000Hz的蜂鳴器的驅(qū)動，可以知道周期為500μs，這樣只需要把PWM的周期設(shè)置為500μs，占空比電平設(shè)置為250μs，就能產(chǎn)生一個頻率為2000Hz的方波，通過這個方波再利用三極管就可以去驅(qū)動這個蜂鳴器了。而利用I/O定時翻轉(zhuǎn)電平來產(chǎn)生驅(qū)動波形的方式會比較麻煩一點，必須利用定時器來做定時，通過定時翻轉(zhuǎn)電平產(chǎn)生符合蜂鳴器要求的頻率的波形。 青浦區(qū)主營AD16系列蜂鳴器廠家供應(yīng)聲音頻率可控，可以做出"多來米發(fā)索拉西"的效果。
