produce sound in delphi

Hello guys

I would like to make a software that could make a sound in hertz to keep away mosquitos.
I did a search and I found some appliances that keep away mosquitos due to the sound.
I know that I can reproduce a sound with my delphi, someone could help me with this?

Thanks

hello, I tested the function to produce sound and I could produce 17000 hertz or 17 khertz.

there is a line  SampleRate: Integer = 44100; // 11025; // 8000, 11025, 22050, or 44100

where I used 44100 to reach a khertz.
