An output power control method and circuit. The method comprises: acquiring an impedance of an earphone inserted into an earphone jack of a terminal, acquiring an output power corresponding to the impedance of the earphone from a preset table of correspondence between the impedance of the earphone and the output power, and outputting the power. The circuit comprises: a detection module (61), an acquisition module (62), and an output module (63). The detection module is configured to acquire the impedance of the earphone inserted into the earphone jack of the terminal. The acquisition module is configured to acquire the output power corresponding to the impedance of the earphone from the preset table of correspondence between the impedance of the earphone and the output power. The output module is configured to output the power. |
