Abstract

The invention relates to the technical field of signal processing, and provides an audio signal playing system and an electronic device. The system comprises two or more than two loudspeakers which are used for respectively playing audio signals of different frequencies, a filtering unit which is used for filtering the input audio signals, and carrying out amplifying and outputting to the corresponding loudspeakers, and a feedback control unit which is used for collecting the audio signals played by two or more than two loudspeakers, identifying the power sizes of the audio signals in different frequencies, and then adjusting the magnification factor of the corresponding frequency of each audio signal filtered by the filtering unit according to the identifying results. The feedback control of the audio playing strength of each loudspeaker is realized, so that the loudness of each loudspeaker is consistent. The audio playing effect of the system is optimized. The audio signal playing system and the electronic device can enable an audience to acquire a good listening experience and are conducive to the promotion and the application of a product.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to an audio signal playing system and electronic equipment. Background technique [0002] It is known that the frequency range of audio signals that can be heard by the human ear is 20 Hz-20 KHz, and is particularly sensitive to low frequency parts in audio signals. In order to make the speaker have a better bass effect and a good treble effect at the same time, the traditional way is to increase the size of the speaker. For example, a speaker with a diameter of 52mm and a height of 26mm has a better performance in the low frequency part of about 160Hz. However, with the miniaturization of electronic equipment, the available space for speakers in electronic equipment is getting smaller and smaller, and it is difficult for large-sized speakers to be suitable for most electronic equipment. [0003] In order to optimize the audio signal playback effect without in...
