Abstract: This application discloses example frequency control methods, frequency controllers, processors, and electronic devices. One example method includes obtaining at least two temperatures of a processor core, where each of the at least two temperatures corresponds to a frequency. A load change mode of the processor core is determined, where the load change mode indicates a change status of a load of the processor core. A target temperature is determined from the at least two temperatures of the processor core based on the load change mode. A frequency of the processor core is adjusted based on the target temperature.

Abstract: An audio output method applied to an electronic device having a proximity sensor, where the method includes obtaining proximity data of the proximity sensor when the electronic device is coupled to an audio output device and has an audio signal to output, outputting, by an earpiece of the electronic device, the audio signal when the proximity data meets a preset condition, determining a type of the audio output device, and selecting, based on the type of the audio output device, whether to output the audio signal using the audio output device. Hence, an earpiece is enabled to output an audio signal under a specific condition when an electronic device including a mobile phone is coupled to another audio output device, thereby improving user experience.
