Abstract
A signal gain control method for an electronic device including an alternating-current (AC) impedance detector and a direct-current (DC) impedance detector is provided. An electronic device may implement the method and may be coupled to an external device. The method includes: detecting an AC impedance of the external device by the AC impedance detector; detecting a DC impedance of the external device by the DC impedance detector; obtaining a gain adjustment value according to the AC impedance and the DC impedance; and adjusting a signal gain of an audio signal output to the external device according to the gain adjustment value.
