The present invention relates to the field of signal processing technologies, and provides an audio signal playback system and an electronic device. The system includes: two or more loudspeakers, configured to separately play audio signals in different frequency bands; a filter unit, configured to filter an input audio signal, amplify and output to the corresponding loudspeakers; and a feedback control unit, configured to collect the audio signals played by the two or more loudspeakers, measure power values of the audio signals in different frequency bands, and adjust, according to an measurement result, a amplification factor of the filter unit for the filtered audio signal in a corresponding frequency band. In this way, feedback control over audio playback strength of the loudspeakers is implemented, so that the loudspeakers have consistent loudness, thereby optimizing the audio playback quality of the system, improving the experience of a listener, and facilitating the promotion and application of a product. |
