Abstract: A method includes: performing interpolation on a second nonlinear parameter of a speaker based on direct current resistance of the speaker to obtain a third nonlinear parameter of the speaker, where the second nonlinear parameter is a nonlinear parameter preconfigured in the speaker; performing signal compensation on a first input signal of the speaker based on the third nonlinear parameter to obtain a compensated first input signal; and performing filtering on the compensated first input signal to obtain an output signal of the speaker.

Abstract: A method includes receiving, by a second electronic device, a first working key sent by a first electronic device, and a first working key set sent by a first server to the second electronic device after the first server determines that a user of the first electronic device is a target user. In response to the second electronic device determining that the first working key set comprises the first working key, determining, by the second electronic device, that a user of the second electronic device is a suspected target user.
