美音蜂鸣器在空调中的应用主要是通过不同的音乐来表达控制器不同状态，或者，对不同操作用不同音乐响应。而不同的 音乐是通过控制芯片内的两个蜂鸣器管脚来控制。一个是控制蜂鸣器的工作情况。而音乐的尾音则是通过关闭控制蜂鸣器，从而附带着 的电容放电所造成的。另一个则是控制蜂鸣器的音乐情况。具体是从晶振到预分频再到分频个计数器的一连 串的控制，进而达到人们想发的音阶、音乐的实现。-US-tone buzzer in the air conditioning system mainly through the control of different music to express different states, or different operations to respond to different music. And different music is by controlling the chip, two pins to control the buzzer. One is to control the buzzer work. The music of the tail is controlled by closing buzzer, which comes with the capacitor discharge caused. The other is to control the buzzer' s situation. Specifically to the prescaler from the crystal frequency counters and then to a series of control, and people want to do to achieve the scale, the realization of music.
