Abstract

This application discloses a sound effect adjustment method and an electronic device. In the method, a first electronic device that plays first audio may indicate a second electronic device to start up an audio collection apparatus, to collect an ambient sound and obtain ambient audio. The second electronic device is an electronic device with a highest possibility that a user carries the electronic device. Based on the first audio and the ambient audio, the first electronic device may determine a difference between a listening sound effect of the first audio at a location of the second electronic device and an optimal sound effect. The first electronic device may adjust an audio parameter for playing the first audio, so that the listening sound effect of the first audio at the location of the second electronic device reaches the optimal sound effect.

First claim

What is claimed is:

1 . A method, wherein the method is applied to a sound effect adjustment system, the sound effect adjustment system comprises a first electronic device and a second electronic device, and a communication connection is established between the first electronic device and the second electronic device;
the first electronic device is configured to play first audio, and the second electronic device is configured to collect second audio in response to determining that the first audio is played; and the method comprises: determining a second sound effect based on the second audio in response to determining that the first audio is played at a first sound effect, wherein the second sound effect is a listening sound effect on the second electronic device of the first audio played at the first sound effect; and determining a playback sound effect of the first audio as a fourth sound effect in response to determining that a difference between the second sound effect and a third sound effect exceeds a first difference, wherein a difference between the third sound effect and a listening sound effect on the second electronic device of the first audio played at the fourth sound effect is less than the first difference, and the third sound effect is an optimal sound effect of the first audio played at the first sound effect, wherein the fourth sound effect is determined based on analyzing the second audio to separate a first audio part corresponding to the first audio and a background noise part, and wherein an audio parameter of the fourth sound effect is adjusted based on the background noise part, such that louder background noise indicated by the background noise part results in greater loudness in the fourth sound effect than in the first sound effect.

2 . The method according to claim 1 , wherein in response to determining that the first audio is played at the first sound effect, a listening sound effect on the second electronic device at a first location is different from a listening sound effect on the second electronic device at a second location.

3 . The method according to claim 1 , wherein the first electronic device or the second electronic device determines the second sound effect based on the second audio in response to determining that the first audio is played at the first sound effect.

4 . The method according to claim 1 , wherein the first electronic device or the second electronic device determines the playback sound effect of the first audio as the fourth sound effect in response to determining that the difference between the second sound effect and the third sound effect exceeds the first difference.

5 . The method according to claim 1 , wherein the sound effect adjustment system further comprises a third electronic device, and a communication connection is established between the first electronic device and the third electronic device; and the third electronic device determines the second sound effect based on the second audio in response to determining that the first audio is played at the first sound effect, and determines the playback sound effect of the first audio as the fourth sound effect in response to determining that the difference between the second sound effect and the third sound effect exceeds the first difference.

6 . The method according to claim 1 , wherein the sound effect adjustment system further comprises a third electronic device, and a communication connection is established between the first electronic device and the third electronic device; and the method further comprises:
selecting, by the first electronic device, one of the second electronic device and the third electronic device based on processing capability strength of the second electronic device and the third electronic device or busy degrees of the second electronic device and the third electronic device, to determine the second sound effect based on the second audio in response to determining that the first audio is played at the first sound effect, or determine the playback sound effect of the first audio as the fourth sound effect in response to determining that the difference between the second sound effect and the third sound effect exceeds the first difference.

7 . The method according to claim 1 , wherein the method further comprises:
providing, by the first electronic device, an option for selecting an electronic device that collects the second audio, wherein the option corresponds to the second electronic device; receiving, by the first electronic device, a user operation of selecting the option corresponding to the second electronic device; and indicating, by the first electronic device, the second electronic device to collect the second audio.

8 . The method according to claim 1 , wherein the method further comprises:
determining, by the first electronic device based on a first priority rule, that the second electronic device is an electronic device with a highest priority in electronic devices that each establish a communication connection to the first electronic device, and indicating the second electronic device to collect the second audio, wherein a principle of determining a priority sequence of the electronic devices in the first priority rule is: determining, based on device types of the electronic devices, possibilities that a user carries each of the electronic devices, wherein a higher possibility corresponds to a higher priority in the first priority rule.

9 . The method according to claim 1 , wherein the second audio comprises a first audio part and a background noise part, the second sound effect is determined based on the first audio part and the background noise part, and louder background noise indicated by the background noise part indicates that loudness in the fourth sound effect is greater than loudness in the first sound effect.

10 . The method according to claim 1 , wherein the second audio comprises a first audio part and a background noise part, and the second sound effect is determined based on the first audio part and the background noise part; and in response to determining that the background noise part comprises a human sound, loudness in the fourth sound effect is the same as loudness in the first sound effect, or loudness in the fourth sound effect is smaller than loudness in the first sound effect.

11 . The method according to claim 1 , wherein by adjusting an audio parameter, the first audio is adjusted from being played at the first sound effect to being played at the fourth sound effect, and the audio parameter comprises one or more of the following: loudness, a parameter in an equalizer, or a parameter in a dynamic range controller.

12 . A method, wherein the method comprises:
playing, by a first electronic device, first audio at a first sound effect, and establishing a communication connection to a second electronic device; receiving, by the first electronic device, second audio from the second electronic device, wherein the second audio is collected by the second electronic device in response to determining that the first audio is played; determining, by the first electronic device, a second sound effect based on the second audio, wherein the second sound effect is a listening sound effect on the second electronic device of the first audio played at the first sound effect; and determining, by the first electronic device, a playback sound effect of the first audio as a fourth sound effect in response to determining that a difference between the second sound effect and a third sound effect exceeds a first difference, wherein a difference between the third sound effect and a listening sound effect on the s
