[0029] The embodiments of the present application will be introduced in detail below.

[0030] Please refer to Figure 1 , Figure 1It is a schematic flowchart of a microphone control method provided by an embodiment of the present application, which is applied to an electronic device. The electronic device includes a microphone, a distance sensor, and a camera. The microphone control method may include the following steps:

[0031] 101. When the microphone is in a sleep state, detect a target distance between the user and the microphone through the distance sensor.

[0032] In an embodiment of the present application, the electronic device may include a microphone, a distance sensor, and a camera. The distance sensor may include at least one of the following: a proximity sensor, a laser range finder, etc., which is not limited herein. The camera may be a dual camera or a depth camera.

[0033] In a specific implementation, when the microphone is in a sleep state, the target distance between the user and the microphone can be detected through the distance sensor.

[0034] 102. Identify a target relative angle between the user and the microphone through the camera.

[0035] In a specific implementation, the target relative angle between a specified position of the user's body and the microphone can be identified through the camera. The specified position may be a certain position on the head, such as the mouth, the left eyebrow, the bridge of the nose, etc. The specified position can be set in advance or be the system default.

[0036] 103. Detect whether the target distance and the target relative angle meet a preset condition.

[0037] Among them, the preset condition can be set in advance or be the system default. The preset condition may also be related to the hardware parameters of the microphone. Different hardware parameters result in different distances or relative angles. The hardware parameters may include at least one of the following: the model of the microphone, the battery level of the microphone, the power of the microphone, etc., which is not limited herein.

[0038] In a specific implementation, if the target distance and the target relative angle need to meet the preset condition, it means that the distance and / or angle between the user and the microphone is good, and then the microphone can be turned on.

[0039] Optionally, in step 103 above, detecting whether the target distance and the target relative angle meet the preset condition may include the following steps:

[0040] A31. Determine a first evaluation value corresponding to the target distance according to a mapping relationship between a preset distance and an evaluation value;

[0041] A32. Determine a second evaluation value corresponding to the target relative angle according to a mapping relationship between a preset relative angle and an evaluation value;

[0042] A33. Obtain the target environmental parameters;

[0043] A34. Determine the target weight pair corresponding to the target environmental parameters;

[0044] A35. Perform a weighted operation based on the target weight pair, the first evaluation value, and the second evaluation value to obtain a target evaluation value;

[0045] A36. When the target evaluation value is within a preset range, confirm that the target distance and the target relative angle meet the preset conditions;

[0046] A37. When the target evaluation value is not within the preset range, confirm that the target distance and the target relative angle do not meet the preset conditions.

[0047] In the embodiments of the present application, a mapping relationship between a preset distance and an evaluation value, and a mapping relationship between a preset relative angle and an evaluation value can be stored in advance.

[0048] In a specific implementation, the target environmental parameters may include at least one of the following: environmental noise value, scene location, scene space size, etc., which are not limited herein. The scene space size may refer to a space where the microphone is located, such as a classroom, a meeting room, outdoors, etc. The preset range can be set in advance or be the system default.

[0049] In the embodiments of the present application, a mapping relationship between a preset distance and an evaluation value, and a mapping relationship between a preset relative angle and an evaluation value can be stored in advance.

[0050] In a specific implementation, the first evaluation value corresponding to the target distance can be determined according to the mapping relationship between the preset distance and the evaluation value, and then the second evaluation value corresponding to the target relative angle can be determined according to the mapping relationship between the preset relative angle and the evaluation value. Moreover, the target environmental parameters can be obtained. Different environmental parameters can correspond to different weight pairs. The weight pair can include a first weight and a second weight. The first weight is the weight corresponding to the first evaluation value, and the second weight is the weight corresponding to the second evaluation value. The sum of the first weight and the second weight is 1. That is, a mapping relationship between the preset environmental parameters and the weight pair can be stored in advance. Furthermore, based on this mapping relationship, the target weight pair corresponding to the target environmental parameters can be determined. The target weight pair can include a target first weight and a target second weight.

[0051] Then, a weighted operation can be performed according to the target weight pair, the first evaluation value, and the second evaluation value to obtain a target evaluation value, that is: target evaluation value = first evaluation value * target first weight + second evaluation value * target second weight.

[0052] Further, when the target evaluation value is within the preset range, it indicates that the angle and distance between the microphone and the user are appropriate before, then it can be confirmed that the target distance and the target relative angle meet the preset conditions. On the contrary, when the target evaluation value is not within the preset range, it indicates that the distance and angle between the microphone and the user are not appropriate, and it is confirmed that the target distance and the target relative angle do not meet the preset conditions.

[0053] Optionally, step 103 above, detecting whether the target distance and the target relative angle meet the preset conditions, may include the following steps:

[0054] B31. Detect whether the target distance is within the preset distance range and detect whether the target relative angle is within the preset relative angle range;

[0055] B32. When the target distance is within the preset distance range and the target relative angle is within the preset relative angle range, confirm that the target distance and the target relative angle meet the preset conditions;

[0056] B33. When the target distance is not within the preset distance range, and / or the target relative angle is not within the preset relative angle range, confirm that the target distance and the target relative angle do not meet the preset conditions.

[0057] In the embodiments of the present application, the preset distance range and the preset relative angle range can both be set in advance or be the system default.

[0058] In specific implementation, it can be detected whether the target distance is within the preset distance range and whether the target relative angle is within the preset relative angle range. When the target distance is within the preset distance range and the target relative angle is within the preset relative angle range, it indicates that both the distance and angle between the microphone and the user are appropriate, and it is confirmed that the target distance and the target relative angle meet the preset conditions. When the target distance is not within the preset distance range, and / or the target relative angle is not within the preset relative angle range, it indicates that either the distance or the angle between the microphone and the user is not appropriate, and it is confirmed that the target distance and the target relative angle do not meet the preset conditions.

[0059] 104. When the target distance and the target relative angle meet the preset conditions, wake up the microphone.

[0060] In the embodiments of the present application, when the target distance and the target relative angle meet the preset conditions, it indicates that the distance and angle between the microphone and the user are appropriate and meet the microphone activation conditions, then the microphone can be woken up.

[0061] Optionally, it may further include the following steps:

[0062] When the target distance and the target relative angle do not meet the preset conditions, control the microphone to remain in the sleep state.

[0063] In the embodiments of the present application, when the target distance and the target relative angle do not meet the preset conditions, it indicates that the distance or angle between the microphone and the user is not appropriate, which does not meet the activation conditions of the microphone. Therefore, the microphone can be controlled to remain in the sleep state, thereby reducing the power consumption of the electronic device and avoiding the unintentional use of the microphone.

[0064] 105. Determine the first working parameter of the microphone according to the target distance and the target relative angle.

[0065] In the embodiments of the present application, the first working parameter may include at least one of the following: the working current of the microphone, the working power of the microphone, the working voltage of the microphone, the voice signal enhancement processing algorithm corresponding to the microphone, the algorithm control parameter of the voice signal enhancement processing algorithm corresponding to the microphone, etc. There is no limitation here. The algorithm control parameter of the voice signal enhancement processing algorithm corresponding to the microphone is used to control the algorithm effect of the voice signal enhancement processing algorithm corresponding to the microphone, and the voice signal enhancement processing algorithm corresponding to the microphone is used to implement functions such as voice noise reduction and voice enhancement.

[0066] Optionally, the first working parameter includes algorithm-related working parameters;

[0067] The above step 105 of determining the first working parameter of the microphone according to the target distance and the target relative angle may include the following steps:

[0068] 51. Determine the target voice signal enhancement processing algorithm according to the target distance;

[0069] 52. Obtain the initial algorithm control parameter corresponding to the target voice signal enhancement processing algorithm;

[0070] 53. Determine the target algorithm adjustment parameter corresponding to the target relative angle;

[0071] 54. Adjust the initial algorithm control parameter according to the target algorithm adjustment parameter to obtain the target algorithm control parameter;

[0072] 55. Use the target voice signal enhancement processing algorithm and the target algorithm control parameter as the algorithm-related working parameters.

[0073] In the embodiments of the present application, the first working parameter may include algorithm-related working parameters, and the algorithm-related working parameters may include the corresponding voice signal enhancement processing algorithm and the corresponding algorithm control parameter.

[0074] In a specific implementation, a mapping relationship between a preset distance and a voice signal enhancement processing algorithm can be preset. Furthermore, based on this mapping relationship, a target voice signal enhancement processing algorithm can be determined according to the target distance. An initial algorithm control parameter corresponding to the target voice signal enhancement processing algorithm can be obtained. The initial algorithm control parameter can be preset in advance or be the system default. A mapping relationship between a preset relative angle and an algorithm adjustment parameter can also be preset. Furthermore, based on this mapping relationship, a target algorithm adjustment parameter corresponding to the target relative angle can be determined. Then, the initial algorithm control parameter is adjusted according to the target algorithm adjustment parameter to obtain a target algorithm control parameter. In this way, an algorithm control parameter corresponding to the relative angle can be obtained. For different relative angles, the mixed environmental noise is different. Furthermore, to a certain extent, the influence of environmental noise can be further reduced. The target voice signal enhancement processing algorithm and the target algorithm control parameter are used as algorithm-related working parameters. In this way, a voice signal enhancement processing algorithm corresponding to the distance and the relative angle and the corresponding algorithm control parameter can be obtained, which helps to improve the noise reduction ability of the microphone and the sound effect of the microphone, and helps to improve the user experience.

[0075] Optionally, the first working parameter includes a hardware-related working parameter;

[0076] The following steps may further be included:

[0077] A1. Obtain target scene environment parameters;

[0078] A2. Determine the hardware-related working parameter corresponding to the target scene environment parameter.

[0079] In the embodiment of the present application, the scene environment parameter may include at least one of the following: scene location, scene space parameter, scene echo parameter, etc., which is not limited herein. The hardware-related working parameter may include at least one of the following: the working current of the microphone, the working power of the microphone, the working voltage of the microphone, etc., which is not limited herein.

[0080] In a specific implementation, a mapping relationship between a preset scene environment parameter and a hardware-related working parameter can be prestored. Furthermore, the target scene environment parameter can be obtained, and based on this mapping relationship, the hardware-related working parameter corresponding to the target scene environment parameter can be determined. In this way, the hardware-related working parameter of the microphone corresponding to a specific scene can be obtained, which helps to improve the noise reduction ability of the microphone and the sound effect of the microphone, and helps to improve the user experience.

[0081] 106. Control the microphone to work with the first working parameter.

[0082] In a specific implementation, the microphone can be controlled to work with first working parameters. Since the first working parameters are related to the distance and angle between the microphone and the user, the working parameters of the microphone are more in line with the actual situation, which helps to improve the noise reduction ability of the microphone and the sound effect of the microphone, and helps to improve the user experience.

[0083] It can be seen that the microphone control method described in the embodiments of the present application is applied to an electronic device. The electronic device includes a microphone, a distance sensor, and a camera. When the microphone is in a sleep state, the target distance between the user and the microphone is detected by the distance sensor, and the target relative angle between the user and the microphone is identified by the camera. It is detected whether the target distance and the target relative angle meet the preset conditions. When the target distance and the target relative angle meet the preset conditions, the microphone is awakened, the first working parameters of the microphone are determined according to the target distance and the target relative angle, and the microphone is controlled to work with the first working parameters. Since the first working parameters are related to the distance and angle between the microphone and the user, the working parameters of the microphone are more in line with the actual situation, which helps to improve the noise reduction ability of the microphone and the sound effect of the microphone, and helps to improve the user experience.
