[0054] Here, the exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0055] First, the application scenario of the present disclosure is introduced. The present disclosure is applied to the scenario of adjusting the noise reduction mode of a terminal. Exemplarily, the terminal may be a wireless earphone, a true wireless stereo (TWS) earphone, etc., which is not limited herein. Figure 1 It is a scenario diagram of a method for controlling a terminal shown according to an exemplary embodiment. The scenario includes a first terminal 110, a second terminal 120, a cellular base station 130, a WIFI access point 140, and a network 150. As Figure 1 shown, the first terminal 110 may be connected to the second terminal 120; the second terminal 120 may access the network 150 through the cellular base station 130 or the WIFI access point 140; the second terminal 120 may implement the function of audio playback through the first terminal 110. Among them, the first terminal 110 may be an earphone, and the second terminal 120 may be a mobile phone, a computer, etc., which is not limited herein.

[0056] Active noise reduction technology is one of the important functions of current earphone devices. With the continuous development of active noise reduction technology, the effect of active noise reduction is also continuously improved. In related technologies, during the process of signal processing through active noise reduction technology, the noise of the environment where the current earphone device is located can be obtained, the optimal noise reduction curve can be determined, and the noise reduction function of the earphone device can be realized by matching a corresponding filter to the noise. However, the above solution is mainly used to reduce environmental noise, and some background noise of devices in the earphone device will be amplified during the noise reduction process, or the noise of other devices will be introduced. The side effects of background noise on the user experience are not considered, which reduces the user experience.

[0057] Therefore, the present disclosure provides a method, an apparatus, an electronic device, and a storage medium for terminal control; by obtaining a first sound feature of the environment where the terminal is located; according to the first sound feature, determining a target feature type representing the frequency range of the ambient noise; according to the target feature type, switching the noise reduction mode of the terminal; by determining the feature type corresponding to the sound feature, thereby adjusting the noise reduction mode of the terminal according to different feature types, realizing the self - adjustment of the noise reduction mode in different noise frequency ranges, reducing the impact of background noise on users, and improving the user experience.

[0058] Figure 2 is a flowchart of a method for terminal control shown according to an exemplary embodiment, as Figure 2 shown, the method is used in a terminal and may include the following steps.

[0059] S201. Obtain a first sound feature of the environment where the terminal is located.

[0060] In some embodiments, the sound information of the environment where the terminal is located may be obtained; based on the spectrum of the sound information, the first sound feature is determined. Exemplarily, the terminal may be an earphone; the sound feature of the environment where it is located may be obtained through the microphone of the earphone. The first sound feature may include the duration of the sound, the loudness of the sound, and the frequency distribution of the sound.

[0061] S202. According to the first sound feature, determine a target feature type representing the frequency range of the ambient noise.

[0062] Exemplarily, the frequency range of the ambient noise may refer to the high and low of the noise frequency, such as high - frequency noise, medium - frequency noise, or low - frequency noise. The target feature type may include a high - frequency noise type, a medium - frequency noise type, or a low - frequency noise type.

[0063] In some embodiments, the above - mentioned determining a target feature type representing the frequency range of the ambient environment according to the first sound feature may include: in the case of determining a target feature range corresponding to the first sound feature from a plurality of preset feature ranges, determining the target feature type according to the target feature range. Exemplarily, the preset feature range may be determined according to the amplitude and frequency range of the sound.

[0064] In some embodiments, the amplitude range and frequency range of the sound can be divided into multiple intervals respectively; and multiple preset feature ranges can be determined according to the multiple intervals. For example, the amplitude range and frequency range of the sound can be divided into 5 intervals respectively, and the specific division results can be shown in Table 1 below. According to the multiple intervals, 25 preset feature ranges can be obtained, such as {(20 - 500Hz), (40 - 50dB)}, {(20 - 500Hz), (50 - 60dB)}, {(1200 - 2000Hz), (40 - 50dB)}, etc., which will not be elaborated here.

[0065] Table 1:

[0066]

[0067] The division of the above interval ranges can be set by the user according to actual needs. Here is just an example and no specific limitation is made.

[0068] In some other embodiments, determining the target feature range corresponding to the first sound feature from multiple preset feature ranges may include: determining a candidate feature range corresponding to the first sound feature from the multiple preset feature ranges; obtaining multiple second sound features of the environment where the terminal is located within a preset time period; and when it is determined that all the multiple second sound features are within the candidate feature range, taking the candidate feature range as the target feature range.

[0069] Exemplarily, the preset time period may be within the range of 1 - 3s, such as 1s, 1.5s, 2s, or 3s, etc., and no limitation is made here.

[0070] In some embodiments, determining the target feature type according to the target feature range may include: taking the feature type corresponding to the target feature range as the target feature type.

[0071] Exemplarily, the feature type corresponding to the target feature range can be determined from multiple preset feature types, and this feature type can be taken as the target feature type.

[0072] Among them, each preset feature range corresponds to a preset feature type. Exemplarily, the corresponding relationship between each preset feature range and each preset feature type can be determined through a first preset correspondence. The first preset correspondence can include the corresponding relationship between multiple preset feature ranges and one preset feature type; or, it can include the corresponding relationship between one preset feature range and one preset feature type. For example, as shown in Table 2 below, the preset feature range can include 6, namely A, B, C, D, E, and F; the preset feature type can include 3, namely Type One, Type Two, and Type Three; A, B, and C correspond to Type One; D and E correspond to Type Two; F corresponds to Type Three.

[0073] Table 2:

[0074] Preset feature type Preset feature range Type 1 A, B, C Type 2 D, E Type 3 F

[0075] In some other embodiments, determining the target feature type representing the environmental noise frequency range according to the first sound feature may include: in the case where the target feature range corresponding to the first sound feature is not determined from multiple preset feature ranges, taking the feature type corresponding to the specified feature range as the target feature type.

[0076] Among them, the specified feature range is the range specified by the user from multiple preset feature ranges; or, the specified feature range is the feature range among multiple preset feature ranges where the difference between the target boundary value and the feature value of the first sound feature is the smallest, and the target boundary value is the boundary value among the boundary values of the preset feature range with the smallest difference from the feature value.

[0077] Exemplarily, the preset feature range may include a first preset boundary value and a second preset boundary value; the first target difference between the feature value of the first sound feature and the first preset boundary value, and the second target difference between the feature value of the first sound feature and the second preset boundary value can be determined; determine the minimum value of the first target difference and the second target difference; take the boundary value corresponding to the minimum value as the target boundary value.

[0078] In some embodiments, the above method may further include: adjusting the specified feature range so that the first sound feature can be within the specified feature range.

[0079] In some other embodiments, the above adjusting the specified feature range so that the first sound feature can be within the specified feature range may include the following two methods:

[0080] Method One: Increase the specified feature range according to a preset value so that the first sound feature can be within the specified feature range.

[0081] Exemplarily, the preset value can be set by the user and is not limited herein. The boundary value of the specified feature range can be increased by the preset value so that the first sound feature can be within the second specified feature range.

[0082] In some embodiments, the specified feature range can be increased multiple times according to the preset value until the first sound feature can be within the second specified feature range. In this way, when the sound feature still cannot fall within the specified feature range after increasing the preset value once, the sound feature can be made to be within the specified feature range by increasing the boundary value of the specified feature range multiple times, thereby improving work efficiency.

[0083] In some other embodiments, when it is determined that the number of times of increasing the specified feature range is greater than or equal to the first preset number threshold, increasing the specified feature range can be stopped. Since increasing the boundary value of the feature range multiple times will affect the division of the overall range, setting the number threshold can reduce the impact on other feature ranges.

[0084] Method 2: Determine the difference between the feature value of the first sound feature and the target boundary value of the specified feature range; increase the specified feature range according to the difference so that the first sound feature can be within the specified feature range.

[0085] Exemplarily, the specified feature range can include a first boundary value and a second boundary value; the first difference between the feature value of the first sound feature and the first boundary value, and the second difference between the feature value of the first sound feature and the second boundary value can be determined; determine the minimum value of the first difference and the second difference; use the boundary value corresponding to the minimum value as the target boundary value. In this way, the specified feature range can be adjusted more accurately, improving work efficiency.

[0086] It should be noted that in the process of increasing the specified feature range according to the target boundary value, the specified feature range can be increased multiple times according to the target boundary value. The specific increasing method can be the same as that of increasing the specified feature range multiple times according to the preset value above and will not be elaborated herein.

[0087] Similarly, when it is determined that the number of times of increasing the specified feature range is greater than or equal to the second preset number threshold, increasing the specified feature range can be stopped. The specific method will not be elaborated herein.

[0088] S203. Switch the noise reduction mode of the terminal according to the target feature type.

[0089] By determining the feature type corresponding to the sound feature, the noise reduction mode of the terminal is adjusted according to different feature types, realizing the self-adjustment of the noise reduction mode in different noise frequency ranges, reducing the impact of background noise on the user, and improving the user experience.

[0090] Figure 3 is a flowchart of a method for terminal control shown according to an exemplary embodiment of Figure 2 . As shown in Figure 3 , the above step S203 may include:

[0091] S2031. Determine a target noise reduction mode corresponding to the target feature type from multiple preset noise reduction modes.

[0092] Among them, different target feature types correspond to different preset noise reduction modes. Exemplarily, the target feature type may include a high-frequency noise type, a medium-frequency noise type, or a low-frequency noise type; the noise reduction mode may include a mild noise reduction mode, an equalized noise reduction mode, or a deep noise reduction mode. The high-frequency noise type may correspond to the deep noise reduction mode, the medium-frequency noise type may correspond to the equalized noise reduction mode, and the low-frequency noise type may correspond to the mild noise reduction mode.

[0093] Exemplarily, the correspondence between each preset feature type and each preset noise reduction mode may be determined through a second preset correspondence relationship. Among them, multiple preset feature types may correspond to one preset noise reduction mode. For example, as shown in Table 3 below, the preset feature type may include Type One, Type Two, Type Three, Type Four, Type Five, and Type Six, and the preset noise reduction mode may include a mild noise reduction mode, an equalized noise reduction mode, and a deep noise reduction mode; Type One and Type Two may correspond to the mild noise reduction mode; Type Three, Type Four, and Type Five may correspond to the equalized noise reduction mode; Type Six may correspond to the deep noise reduction mode.

[0094] Table 3:

[0095] Preset noise reduction mode Preset feature type Light noise reduction mode Type 1, Type 2 Balanced noise reduction mode Type 3, Type 4, Type 5 Deep noise reduction mode Type 6

[0096] S2032. Switch the noise reduction mode of the terminal to the target noise reduction mode.

[0097] In this way, automatic switching of the terminal noise reduction mode can be achieved without manual switching of the noise mode; moreover, the matching of the noise reduction mode with the current scene where the terminal is located is realized, reducing the influence of background noise and other noises on the user perception and improving the user experience.

[0098] In some embodiments, the method may further include: when the target feature type representing the environmental noise frequency range cannot be determined according to the first sound feature, switching the noise reduction mode of the terminal to a specified noise reduction mode.

[0099] Exemplarily, the specified noise reduction mode may include a mild noise reduction mode, an equalized noise reduction mode, or a deep noise reduction mode. By the above method, the mode can be directly switched, so as to quickly adjust the noise reduction mode of the terminal and improve the user experience.

[0100] Figure 4 is a flowchart of another method for controlling a terminal shown according to an exemplary embodiment. Referring to Figure 4 , the method may include the following steps:

[0101] S401. Obtain a first sound feature of the environment where the terminal is located.

[0102] S402. Determine whether there is a target feature range corresponding to the first sound feature from multiple preset feature ranges.

[0103] If it is determined that the target feature range exists, execute steps S403 - S404; if the target feature range is not determined, execute step S405.

[0104] S403. Use the feature type corresponding to the target feature range as the target feature type.

[0105] S404. Use the feature type corresponding to the specified feature range as the target feature type.

[0106] Wherein, the specified feature range is a range specified by the user from multiple preset feature ranges; or, the specified feature range is the range in multiple preset feature ranges with the smallest difference between the target boundary value and the feature value of the first sound feature, and the target boundary value is the boundary value with the smallest difference from the feature value among the boundary values of the preset feature range.

[0107] S405. Determine a target noise reduction mode corresponding to the target feature type from multiple preset noise reduction modes.

[0108] Wherein, different target feature types correspond to different preset noise reduction modes.

[0109] S406. Switch the noise reduction mode of the terminal to the target noise reduction mode.

[0110] By determining the feature range where the sound feature is located, the scene classification of the sound feature is realized, so as to adjust the noise reduction mode of the terminal according to different scenes, realize the self - adjustment of the noise reduction mode in different scenes, reduce the influence of background noise on the user, and improve the user experience.
