Abstract

Embodiments of this application provide a volume adjustment method and an electronic device. The volume adjustment method includes: receiving target volume used when a media playing device plays content; obtaining an audio signal, where the audio signal includes a first signal and a second signal, the first signal is a sound signal that is collected by a wearable device worn by a user and that is generated when the media playing device plays the content, and the second signal is a noise signal collected by the wearable device; determining adjusted volume based on the audio signal and the target volume; and sending the adjusted volume to a target device through a communication connection to the target device, where the adjusted volume is used to update volume used when the media playing device plays the content.

First claim

What is claimed is:

1. A method, applied to a first electronic device, wherein the method comprises:
receiving a target volume for when a media playing device plays content;
obtaining an audio signal, wherein the audio signal comprises a first signal and a second signal, the first signal is a sound signal that is collected by a wearable device worn by a user and that is generated when the media playing device plays the content, and the second signal is a noise signal on a user side that is collected by the wearable device;
determining adjusted volume based on the audio signal and the target volume, wherein determining the adjusted volume based on the target volume, the first signal, and the second signal comprises:
determining received volume based on the first signal;
determining an adjustment base based on the received volume and the target volume;
determining an enhancement value based on the noise signal on the user side; and
determining the adjusted volume based on the adjustment base and the enhancement value; and

sending the adjusted volume to a target device through a communication connection to the target device, wherein the target volume for when the media playing device plays the content is updated based on the adjusted volume.

2. The method according to claim 1 , wherein when the first electronic device is the wearable device, the target device is the media playing device.

3. The method according to claim 2 , wherein the audio signal is collected by the wearable device, and determining the adjusted volume based on the audio signal and the target volume comprises:
sending the audio signal and the target volume to a second electronic device; and
receiving the adjusted volume from the second electronic device, wherein the adjusted volume is determined by the second electronic device based on the audio signal and the target volume.

4. The method according to claim 1 , wherein when the first electronic device is an electronic device other than the wearable device, the target device is the media playing device.

5. The method according to claim 1 , wherein when the first electronic device is an electronic device other than the wearable device, the target device is the wearable device.

6. The method according to claim 1 , wherein determining the adjusted volume based on the audio signal and the target volume further comprises:
separating out the first signal and the second signal from the audio signal; and
determining the adjusted volume based on the target volume, the first signal, and the second signal.

7. The method according to claim 4 , wherein determining the adjustment base based on the received volume and the target volume comprises:
determining a volume weakening degree based on the received volume and the target volume; and
determining the adjustment base based on the volume weakening degree.

8. The method according to claim 4 , wherein determining the enhancement value based on the noise signal on the user side comprises:
determining a noise intensity level based on the noise signal on the user side; and
determining the enhancement value based on the noise intensity level.

9. An electronic device, comprising a processor and a memory, wherein the processor is coupled to the memory, the memory is configured to store a computer program, and when the processor executes the computer program, the electronic device is enabled to perform steps in the method according to claim 1 .

10. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium comprises a computer program, and when the computer program is run on a computer, the computer is enabled to perform steps in the method according to claim 1 .

11. A chip, comprising a processor, wherein the processor is coupled to a memory, the memory is configured to store computer program instructions, and when the processor executes the computer program instructions, the chip is enabled to perform steps in the method according to claim 1 .

12. A system, wherein the system comprises:
a first electronic device; and
a media playing device having a communication connection with the first electronic device, wherein the media playing device is configured to play content at a target volume and send, to the first electronic device, the target volume of when the media playing device plays the content;
wherein the first electronic device is configured to:
receive the target volume of when the media playing device plays the content;
collect an audio signal, wherein the audio signal comprises a first signal and a second signal, the first signal is a sound signal that is collected by a wearable device worn by a user and that is generated when the media playing device plays the content, and the second signal is a noise signal on a user side that is collected by the wearable device;
determine adjusted volume based on the audio signal and the target volume; wherein determining the adjusted volume based on the audio signal and the target volume comprises:
determining a received volume based on the signal;
determining an adjustment base based on the received volume and the target volume;
determining an enhancement value based on the noise signal on the user side; and
determining the adjusted volume based on the adjustment base and the enhancement value; and

send the adjusted volume to the media playing device through the communication connection, wherein the target volume for when the media playing device plays the content is updated based on the adjusted volume; and

wherein the media playing device is further configured to: in response to receiving the adjusted volume, adjust, based on the adjusted volume, the target volume of when the media playing device plays the content.

13. The system according to claim 12 , further comprising:
a second electronic device having a communication connection between the second electronic device and the first electronic device, wherein the first electronic device being configured to determine the adjusted volume specifically comprises the first electronic device being configured to send the audio signal and the target volume to the second electronic device, and
wherein the second electronic device is configured to: determine the adjusted volume based on the audio signal and the target volume, and send the adjusted volume to the first electronic device.

14. The system according to claim 13 , wherein the first electronic device or the second electronic device is configured to:
separate out the first signal and the second signal from the audio signal; and
determine the adjusted volume based on the target volume, the first signal, and the second signal.

15. The system according to claim 13 , wherein the first electronic device being configured to determine the adjustment base based on the received volume and the target volume comprises the first electronic device being configured to:
determine a volume weakening degree based on the received volume and the target volume; and
