電路原理圖:蜂鳴器如圖1-3所示,使用SH69P43為控制芯片,使用4MHz晶振作為主振蕩器。,而。另外在,一個是PWM按鍵,是用來控制PWM輸出口驅(qū)動蜂鳴器使用的;另一個是PORT按鍵,是用來控制I/O口驅(qū)動蜂鳴器使用的。連接按鍵的I/O口開內(nèi)部上拉電阻。軟件設(shè)計方法先分析一下蜂鳴器。所使用的蜂鳴器的工作頻率是2000Hz,也就是說蜂鳴器的驅(qū)動信號波形周期是500μs,由于是1/2duty的信號,所以一個周期內(nèi)的高電平和低電平的時間寬度都為250μs。軟件設(shè)計上,我們將根據(jù)兩種驅(qū)動方式來進行說明。 壓電式蜂鳴器主要由多諧振蕩器、壓電蜂鳴片、阻抗匹配器及共鳴箱、外殼等組成。生產(chǎn)AD16系列蜂鳴器貨源充足
