Wrong, the rear part of the earpiece speaker for the 13 pro does not look anything close to that. There's videos on the internet that disprove you, there's common sense that disproves you, you can watch a jerryrig teardown of the phone and it will disprove you, but it seems you're so adamant on your stance, despite it being demonstrably wrong, that I sincerely doubt you'd believe apple's own engineers if they told you it's not true.

That metal piece did not come from OP's phone.
