Here’s Why There’s A Tiny Hole Next To Your iPhone Camera.
Where are the other two microphones?
Aside from the back, middle button, the other two are located at the bottom of the phone and the front. The last one is under the grill with the phone speaker. This microphone is not active during a phone conversation.
The purpose of the bottom and top one is to give clearer sound.
The one in the back is used when someone is speaking.
Apple is working hard so your ear won't have to.
The earpiece in the iPhone not only does noise cancellation when you are speaking but also what you are hearing from the person you are speaking with.
The microphones take up 20% less space than its predecessor.

Wideband audio or HD Voice allows for the sound spectrum to be the closest and truest human speech range.
