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.

Claim (Index 19):
The electronic device of  claim 11 , further comprising:\n an audio input circuit in communication with the gain control circuit and configured to provide an audio signal to the gain control circuit; a driving circuit, in communication with the gain control circuit, and configured to drive a gain adjusted audio signal received from the gain control circuit; a connection interface, in communication with the driving circuit, the DC impedance detector and the AC impedance detector, configured to connect the external device to the electronic device, to pass the gain adjusted signal driven by the driving circuit to the external device, and to provide signals indicative of the DC impedance and the AC impedance to the DC impedance detector and AC impedance detector, respectively.
