本文給大家分享的是Beep函數的用法以及會使揚聲器發出簡單的聲音的示例，有需要的小伙伴可以參考下•以前，我聽過一個神犇用C++函數做的音樂，當時的心裡就十分激動：哇，好厲害啊，好神啊。
•這次，我終於通過自己無助的盲目的摸索、研究，寫出了這篇文章（此時我的內心是雞凍的233）
下面是正文：
•其實啊，Windows API 就提供了一個這樣奇妙的發音函數，它就是Beep函數。Beep可以通過控制主板揚聲器的發聲頻率和節拍來演奏美妙的旋律，本文根據音樂簡譜來演奏幾首優美的歌曲，用以展現Beep的瘋狂魅力。
首先我們來Beep的函數原型：
BOOL Beep( DWORD dwFreq; DWORD dwDuration; );
參數說明：
•dwFreq 指定要發出的頻率(HZ)
•dwDuration 指定發音的時長，以毫秒為單位。
Beep的實際應用
•比如說我要發do這個音，do應該是523hz，且如果要發一拍的話，就相當於400毫秒。
•那這個函數就成了這樣：Beep(523,400);
•但是，如果我們要連續的發出多個音的話，比如說像這樣：
Beep(523,400);//do Beep(578,400);//re Beep(659,400);//mi
•那豈不是太麻煩了，所以，我建議大家用define函數宏定義一下這些音，比如說這樣：#define re 578和#define mi 659，這樣，上面的三行語句就簡化了成這樣：
Beep(do,400); Beep(re,400); Beep(mi,400);
最終，給親們送上一份表（借別人的 劃去)
其中，q前綴為低音，1後綴為高音，s前綴為半音階
#define qdo 262 #define qre 294 #define qmi 330 #define qfa 349 #define qso 392 #define qla 440 #define qsi 494 #define do 523 #define re 578 #define mi 659 #define fa 698 #define so 784 #define la 880 #define si 988 #define do1 1046 #define re1 1175 #define mi1 1318 #define fa1 1480 #define so1 1568 #define la1 1760 #define si1 1976 #define sqdo 277 #define sqre 311 #define sqfa 370 #define sqso 415 #define sqla 466 #define sdo 554 #define sre 622 #define sfa 740 #define sso 831 #define sla 932 #define sdo1 1046 #define sre1 1245 #define sfa1 1480 #define sso1 1661 #define sla1 1865
最後，（嘿，同志們，別跑，後面還有彩蛋呢！）
好吧，是一首用Beep函數演奏的天空之城
