SOLVED: Where does this cubic rubber pad go to? - iPhone 4S

Where does this cubic rubber pad go to?

So I changed connector dock and slick USB and micro part in my mother's iphone 4s.

After all was done I had 1 spare part that I did not know where it came from.

Now when I talk to my mother I hear my voice echoed realy loud.

I am sure it has to do with this part.

Please help, I could not find it even on exploded views.

Thank you!!!

could this be the cause of the problem?

I'm not sure, never had this issue on an iPhone 4s though, I do repair iPhones on like a daily basis, had that come loose rarely on repairs.
