Abstract

The embodiment of the invention provides an input power control method and device and terminal equipment, relates to the technical field of communication, and aims to solve the problem that the loudspeaker is damaged because the temperature of the loudspeaker cannot be accurately controlled by the existing terminal equipment. The method comprises the following steps: obtaining first output power,wherein the first output power is the output power of a loudspeaker in the terminal equipment; obtaining a target temperature according to the first output power, the target temperature being the temperature of the loudspeaker when the output power of the loudspeaker is the first output power; and adjusting the input power of the loudspeaker according to the target temperature. The method can be applied to a scene of controlling the temperature of the loudspeaker.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to an input power control method and device, and a terminal device. Background technique [0002] At present, terminal equipment often uses small speakers as audio output devices. Since the power of small speakers is relatively small, when the power of the audio signal is large, the temperature of the speaker (such as the temperature of the voice coil in the speaker) may increase. If the temperature of the speaker exceeds the safe temperature of the speaker, the speaker may be damaged. [0003] In order to solve the above problem, the terminal device may acquire the power of the audio signal to be input into the speaker, and estimate the temperature that the speaker may reach when playing the audio signal according to the power. When the estimated temperature of the speaker is greater than the safe temperature of the speaker, the terminal devic...
