Apple iPhone 11 Pro diagram excerpt describing the earpiece receiver and its audio amplifier circuit, stored in a 314 KB RAR archive. It is handy when callers cannot be heard through the top speaker, letting you follow the amplifier outputs, supply and control lines toward the receiver flex. No logic board revision is stated in the name, so match designators with your board first. Rule out a faulty speaker or flex cable before reworking the amplifier chip, and compare readings with a working phone where possible.
