Don't bother, it's not worth it.

 

You would need a piezoelectric buzzer but also some circuitry to produce the signal to make the piezo buzz at the optimal frequency... the pcb lacks that circuit.

I have a Harbor Freight multimeter (Cen-Tech 98025) that I like to use. My only issue with it is that it doesn't beep at me when I get continuity, and I've searched online and can't find a way to add a speaker. I see one iFixit post adding a speaker to a different model, but mine looks a little different. Any ideas?
