Abstract

This application relates to wearable devices and sound pickup methods. An example method includes: displaying a first interface in response to a first operation, where the first interface is used to configure a sound pickup direction; and determining a target sound pickup direction in response to a second operation detected on the first interface. In some instances, the electronic device can provide a sound pickup direction configuration function by using the first interface, so that a user can select the target sound pickup direction based on an actual application situation, and the electronic device can directly pick up a sound signal based on the target sound pickup direction in a subsequent sound pickup process, or perform signal enhancement processing on a picked-up original sound signal based on the target sound pickup direction to obtain an enhanced sound signal in the target sound pickup direction in the original sound signal.

First claim

1 . A wearable device, wherein:
the wearable device comprises a microphone array, and the microphone array comprises at least one directional microphone; and directions of sound pickup beams of the at least one directional microphone are orthogonal to each other.

2 . The wearable device according to claim 1 , wherein the microphone array further comprises at least one omnidirectional microphone.

3 . The wearable device according to claim 1 , wherein the wearable device is configured to: in response to at least detecting a target sound pickup direction, enable a first microphone that is in the microphone array and that points to the target sound pickup direction, and disable a second microphone that is in the microphone array and that does not point to the target sound pickup direction.

4 . The wearable device according to claim 1 , wherein the wearable device is configured to: in response to at least detecting that a first directional microphone that meets a preset condition exists in the microphone array, enable the first directional microphone, and disable a second directional microphone, wherein the preset condition is that signal quality of a sound signal picked up by the first directional microphone is higher than signal quality of a sound signal picked up by the second directional microphone in a preset time period.

5 . The wearable device according to claim 1 , wherein the wearable device is smart glasses.

6 . The wearable device according to claim 5 , wherein when the microphone array comprises one omnidirectional microphone, the omnidirectional microphone is located in a bridge or a nose pad of a rim of the smart glasses.

7 . The wearable device according to claim 5 , wherein when the microphone array comprises two omnidirectional microphones, the two omnidirectional microphones are respectively located on two temples of the smart glasses, or the two omnidirectional microphones are respectively located in positions that are on two sides of rims of the smart glasses and that are close to two temples.

8 . The wearable device according to claim 5 , wherein when the microphone array comprises more than two omnidirectional microphones, the more than two omnidirectional microphones are distributed in a middle area and two side areas of the smart glasses, the middle area comprises at least one of a) a bridge or b) nose pads of rims of the smart glasses, and the two side areas comprise at least one of a) two temples of the smart glasses or b) positions that are on two sides of the rims of the smart glasses and that are close to the two temples.

9 . The wearable device according to claim 1 , wherein the at least one directional microphone is a figure-8 microphone.

10 . A sound pickup method, applied to a sound pickup device, wherein the method comprises:
receiving a target sound pickup direction sent by an electronic device; and obtaining a target sound signal in the target sound pickup direction.

11 . The method according to claim 10 , wherein the obtaining a target sound signal in the target sound pickup direction comprises:
collecting an original sound signal; and performing enhancement processing on the original sound signal based on the target sound pickup direction to obtain an enhanced sound signal of a first sound signal in the target sound pickup direction in the original sound signal, wherein the enhanced sound signal is the target sound signal.

12 . The method according to claim 10 , wherein the obtaining a target sound signal in the target sound pickup direction comprises:
enabling, based on the target sound pickup direction, a first microphone that points to the target sound pickup direction, and disabling a second microphone that does not point to the target sound pickup direction; and collecting the target sound signal by using the enabled first microphone that points to the target sound pickup direction.

13 . The method according to claim 10 , wherein the obtaining a sound signal in the target sound pickup direction comprises:
enabling, based on the target sound pickup direction, a first microphone that points to the target sound pickup direction, and disabling a second microphone that does not point to the target sound pickup direction; collecting an original sound signal by using the enabled first microphone that points to the target sound pickup direction; and performing enhancement processing on the original sound signal based on the target sound pickup direction to obtain an enhanced sound signal of a first sound signal in the target sound pickup direction in the original sound signal, wherein the enhanced sound signal is the target sound signal.

14 . The method according to claim 10 , wherein the method further comprises: playing the target sound signal.

15 . The method according to claim 10 , wherein the method further comprises: sending the target sound signal to an audio playing device.

16 . A computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions for execution by a computer device to enable the computer device to perform:
receiving a target sound pickup direction sent by an electronic device; and obtaining a target sound signal in the target sound pickup direction.

17 . The computer-readable storage medium according to claim 16 , wherein the obtaining a target sound signal in the target sound pickup direction comprises:
collecting an original sound signal; and performing enhancement processing on the original sound signal based on the target sound pickup direction to obtain an enhanced sound signal of a first sound signal in the target sound pickup direction in the original sound signal, wherein the enhanced sound signal is the target sound signal.

18 . The computer-readable storage medium according to claim 16 , wherein the obtaining a target sound signal in the target sound pickup direction comprises:
enabling, based on the target sound pickup direction, a first microphone that points to the target sound pickup direction, and disabling a second microphone that does not point to the target sound pickup direction; and collecting the target sound signal by using the enabled first microphone that points to the target sound pickup direction.

19 . The computer-readable storage medium according to claim 16 , wherein the obtaining a sound signal in the target sound pickup direction comprises:
enabling, based on the target sound pickup direction, a first microphone that points to the target sound pickup direction, and disabling a second microphone that does not point to the target sound pickup direction; collecting an original sound signal by using the enabled first microphone that points to the target sound pickup direction; and performing enhancement processing on the original sound signal based on the target sound pickup direction to obtain an enhanced sound signal of a first sound signal in the target sound pickup direction in the original sound signal, wherein the enhanced sound signal is the target sound signal.

20 . The computer-readable storage medium according to claim 16 , wherein the method further comprises: playing the target sound signal.
