Basically my sister has a pair of USB speakers that get their power and audio through USB nothing else. She now wants to start using them with her iPhone, but it has no 3.5mm input. I was wondering if I purchased a USB sound card, like this

And a male to male adapter like this

Plugged the iPhone into the sound card and the USB cable from the speakers would it work?
I was looking for a powered sound card because I don't know how the sound card or the speakers will get power plus the sound card may only be one way right? (USB to 3.5mm not 3.5mm to USB)
