One I've found is this: 154PZ14480LF-LA: JAMECO VALUEPRO: Electromechanical
That's a piezo transducer, not a buzzer. The difference being that this would need a pwm signal from a microcontroller like a Picaxe. You can't just connect DC across it.
12v peak to peak, means +6 then -6 . So a 6v AC signal*
If you did wanna run this off a picaxe, the data sheet says it will run off as little as 5V p-p .
* Someone double check that Physics A-Level was ages ago.
