    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(jìn)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(jìn)行說明了,。這里只對必須用1/2duty的方波信號進(jìn)行驅(qū)動的他激蜂鳴器進(jìn)行說明,。單片機(jī)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(jìn)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(jī)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(diǎn)，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。 外殼（亥姆霍茲共振聲腔）頻率,、磁環(huán)的磁強(qiáng)漆包線的線徑有直接關(guān)系,。蘇州制造AD16系列蜂鳴器費(fèi)用是多少
