Downed Model Locator( it is buzzing too low)

[MTLM]

I just made my first project. A Downed Model Locator. The problem is that it is buzzing too low for my liking...
Anybody knows how to make it sounds louder?

Thank you,

The loudness of the beeper is determined by its quality (RadioShack parts have very low quality) and the voltage that powers it. Its sound output hole should not be covered.
