can i plug my iphone into it and use it as a speaker?

Yes, there is a AUX input jack.

I can’t figure out what the trigger does. As soon as I turn it on it stays on. Anybody have info for me?

The trigger is there in case you don't want to have the megaphone on at all times. You can press the trigger to activate the microphone only, all the other functions will not work while pressing the trigger.

Is it loud enough to interrupt a concert?

I’m unsure if it would interrupt a concert, but it’s loud enough to be heard across a heavy traffic intersection
