I was looking for a sun stone in platinum, and a fire trap appeared. I was on my3ds, so I didnt know what to do. plz help
Actually, there is a mic on the 3ds, right next to the START button.
So, the method is the same, just blow in it.
Here a link that explains where it is located.
Also, other links that may come in handy for you:

Hope this helped!
After a careful examination of my 3DS console, I can confirm that the only speakers are one the right and left of the top screen. Blowing into these should put out the fire. That's how it worked on the DS Lite.
