驅(qū)動(dòng)方式蜂鳴器由于自激蜂鳴器是直流電壓驅(qū)動(dòng)的,不需要利用交流信號(hào)進(jìn)行驅(qū)動(dòng),只需對(duì)驅(qū)動(dòng)口輸出驅(qū)動(dòng)電平并通過(guò)三極管放大驅(qū)動(dòng)電流就能使蜂鳴器發(fā)出聲音,很簡(jiǎn)單,這里就不對(duì)自激蜂鳴器進(jìn)行說(shuō)明了。這里只對(duì)必須用1/2duty的方波信號(hào)進(jìn)行驅(qū)動(dòng)的他激蜂鳴器進(jìn)行說(shuō)明。單片機(jī)驅(qū)動(dòng)他激蜂鳴器的方式有兩種:一種是PWM輸出口直接驅(qū)動(dòng),另一種是利用I/O定時(shí)翻轉(zhuǎn)電平產(chǎn)生驅(qū)動(dòng)波形對(duì)蜂鳴器進(jìn)行驅(qū)動(dòng)。PWM輸出口直接驅(qū)動(dòng)是利用PWM輸出口本身可以輸出一定的方波來(lái)直接驅(qū)動(dòng)蜂鳴器。在單片機(jī)的軟件設(shè)置中有幾個(gè)系統(tǒng)寄存器是用來(lái)設(shè)置PWM口的輸出的,可以設(shè)置占空比、周期等等,通過(guò)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(gè)時(shí)候利用這個(gè)波形就可以驅(qū)動(dòng)蜂鳴器了。比如頻率為2000Hz的蜂鳴器的驅(qū)動(dòng),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(gè)頻率為2000Hz的方波,通過(guò)這個(gè)方波再利用三極管就可以去驅(qū)動(dòng)這個(gè)蜂鳴器了。而利用I/O定時(shí)翻轉(zhuǎn)電平來(lái)產(chǎn)生驅(qū)動(dòng)波形的方式會(huì)比較麻煩一點(diǎn),必須利用定時(shí)器來(lái)做定時(shí),通過(guò)定時(shí)翻轉(zhuǎn)電平產(chǎn)生符合蜂鳴器要求的頻率的波形。 寶山區(qū)訂做AD16系列蜂鳴器價(jià)格實(shí)惠
