This sonalert buzzer works well in my electronic project. I used 5v power supply and it works perfectly.nbsp;

Works, but louder than expected. Used to replace broken speaker in my driveway alarm.

I used one of these to make a long-reach continuity tester. With 5 or 6 meters of 22 AWG wire and associated resistance, I figured it would take something in the middle of the rated 3V to 24V range. However, I started with a 3V coin cell battery, and got a nice clear sound, plenty loud enough for the application. (Can't imagine what an ear-piercer it would be at 24V.) It emits a beeeeeeeeeeep with no buzzer-ish sound. Didn't measure the pitch.

I used these to make 12 volt testers, this way I can hook this inline on a circuit, then work the system and listen for the buzz. They work very well for my application.

I used one of these to connect to a keyless entry system of a car so that it makes a subtle beep when you press the unlock or lock button. It makes a nice beep sound with 12v of power. I was worried it would be too loud or too quiet for the application I was using it for, but it turned out to be just perfect. I did notice that all 5 of the piezo buzzers make a slightly different tone with the same amount of power, which could be good if you wanted a slightly lower or higher tone in the beep.
