I replaced my charging port and needed to move the loudspeaker. When I put my loudspeaker back in my phone I noticed it doesn't work. I believe this also houses the vibration mechanic, and the phone vibrates.

My question is: How does the loudspeaker actually connect to the phone? From what I can see it's just a floating piece with no type of connector from this piece to the phone. I would like to verify if I may have connected it incorrectly before I purchase another loudspeaker.
