Beep is crazy, so make your motherboard happy.

The main board can sing and play beautiful music based on the music. Do you believe it? Believe it or not, I believe it, ^ _ ^.

Windows API provides such a wonderful pronunciation function, which is the beep function. Beep can be used to control the voice frequency and festival beats of the Main Board speaker to play beautiful music. This article uses the music notation to play several beautiful songs to show beep's crazy charm.

First, let's refer to the beep function prototype:

BOOL Beep(  DWORD dwFreq,  DWORD dwDuration);

Parameter description:

Dwfreq specifies the frequency to be sent (from 37hz to 32767Hz)
Dwduration specifies the pronunciation length in milliseconds.

According to the profile, we know that music scores used for music performances are composed of syllables and beats. Different syllables are sounds of different frequencies. Let's take a look at the imitation syllables of the PC motherboard speakers:
