It does what you'd expect...

This thing is LOUD! I used it for a few projects, one of which is an alarm clock. You can only really stand it if you pulse it for half a second or so. It should be noted that if you have a decent power supply (like a lipo battery) you can actually make this sound off at much lower voltages than 6v. I had it working off a 3.3v pin on my ESP8266. For your information: The jack is positive centre, meaning that the tip is positive and the base is negative.

Il fait ce que vous attendez ...

Cette chose est LOUD! Je l'ai utilisé pour quelques projets, dont l'un est un réveil. Vous ne pouvez vraiment le supporter que si vous le palpez pendant une demi-seconde environ. Il convient de noter que si vous avez une alimentation correcte (comme une batterie lipo), vous pouvez réellement émettre ce son à des tensions beaucoup plus basses que 6v. Je l'avais travailler sur une broche 3.3v sur mon ESP8266. Pour votre information: le cric est au centre positif, ce qui signifie que la pointe est positive et la base négative.
