2008 Nissan maxima 140000

Wassup Eric I have a concern I like you to help me with. My car has been making a whinning sound coming from passenger side front and recently the battery died while it was on acc. I jumped started the car but I noticed that the whinning turned more to a rattle and louder so I popped the hood and found that the alternator was vibrating really bad. Does this mean it’s going bad or could it be a fuse or something else. I would like your professional opinion. Also I have not had any issue with lights in the car, headlights or any electronics.
