The Audio IC chip is in charge of all, if not most, of the audio functions in the iPhone 7 series. Its purpose is to receive all the information from the two microphones located in the iPhone. It is connected to the motherboard here, underneath the SIM tray, via 'balls' that are soldered to the iPhone and to the Audio IC Chip.
