![Adafruit Piezo Buzzer - PS1240 [ADA160]](https://m.media-amazon.com/images/I/51Aa1XTqE1L.jpg)
Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz, but works quite well from 2KHz to 10KHz. For extra loudness, you can connect both pins to a microcontroller and swap which pin is high or low ('differential drive') for double the volume.

Not as loud as expected
They made a point to say how loud this little guy was, but to be honest it is not much louder than any of the other buzzers I have used.Nice buzzer. not super loud.

Ziemlich schwach
Habe versucht den Buzzer an einem Raspberry Pi zu nutzen. Selbst mit einer Verstärker Schaltung ist der Ton der rauskommt so schwach, dass es eigentlich komplett nutzlos ist.
