@dsandife sorry but glue will not work. you will have to solder the connector back on so your speaker will function again. If you have broken traces from pulling the connector off you can use some thin wire to create a jumper for that.

@dsandife thank you for posting your images. That looks like a straight forward repair. You will need a good soldering iron and some sort of magnification source to repair. Pad are good and traces are intact. If you have never soldered on a board before I would suggest to just get it someone who has. Since everything is intact, cost will be minimal. Again, glue will not work!
