How to fix a micro usb adapter for iphone?

I have a micro usb adapter for iphone (AUVIO) and i'm plugging it to my USB cable and it is very lose, its not charging my iphone anymore the inside is making lose noises if i move the piece around. How can i fx this?

I don't think you can. Something may have snapped inside the adapter thus making it faulty. My only solution is to get a new one.
