Default Lipo Sounder/Speaker

My speaker/sounder fell of my HRPoly-X lipo alarm and I could not find it. I was going to solder another speaker on it after I bought one but I could not find one at Radio Shack on-line. I haven't invested much time looking for it because my heli was down and I was waiting for parts, but now I need to find something before I damage a battery. The alarm they had on it was to low and I wanted something that's louder or maybe a bright light strip. Anyone know where I can find these items. Any suggestion would be appreciated.

Thanks!

Andre

You could replace the whole alarm with this one:

you need to measure the voltage for the speaker, and then you can buy a buzzer at radioshack.... 3v, 5v, 12v seem to be the common types(for dc buzzers)
