[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0036] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0037] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0038] Active noise reduction headphone technology can achieve the purpose of noise reduction by identifying environmental noise and sending out an opposite sound wave to cancel out the noise. However, most of the current products are designed for adults and do not take the needs of children into consideration. For example, existing headphones require manual adjustment of the noise reduction level, but children lack good judgment in adjusting the noise reduction level, so the adjustment effect is often poor, and the manual adjustment method is also very inconvenient. There are also some products that automatically adjust the noise reduction level according to the environmental noise. Since they are designed for adults, they are not very suitable for children and cannot meet the needs of children and parents.

[0039] In view of this, an embodiment of the present application provides a headphone noise reduction method, which obtains scene information corresponding to the headphone while maintaining connection with the headphone; determines a target noise reduction strategy corresponding to the scene information; and sends the target noise reduction strategy to the headphone so that the headphone performs noise reduction according to the target noise reduction strategy. The method can automatically determine the target noise reduction strategy for the headphone noise reduction according to the scene in which the headphone is located, thereby improving the accuracy of noise reduction strategy selection and being convenient for children to use.

[0040] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0041] Figure 1 The present invention provides a flowchart of an implementation method of a headphone noise reduction method. The method can be applied to electronic devices, which can be various types of devices with information processing capabilities during implementation. For example, the electronic device can include a personal computer, a laptop, a PDA or a server, etc.; the electronic device can also be a wearable device, such as a smart watch, a smart bracelet or smart glasses, etc.; the electronic device can also be a mobile terminal, such as a mobile phone, a car computer, a tablet computer or a projector, etc. Figure 1 As shown, the method may include the following steps 101 to 103:

[0042] Step 101: While maintaining connection with the headset, obtain scene information corresponding to the headset.

[0043] It should be noted that, when the electronic device is connected to the headset, it can obtain the scene information corresponding to the headset in a variety of ways. For example, the headset can transmit the obtained scene information to the electronic device, or the headset sends the relevant information to the electronic device, and the electronic device processes the relevant information to obtain the scene information, etc. The embodiment of the present application does not limit the method for obtaining the scene information corresponding to the headset.

[0044] Exemplarily, the determined scene information may be: commuting to school on the subway, traveling by plane, on the way home, etc.

[0045] Step 102: Determine a target noise reduction strategy corresponding to the scene information.

[0046] It should be noted that after determining the scene information corresponding to the headphones, the target noise reduction strategy can be determined based on the scene information. The determination method can be based on the correspondence between the scene information and the noise reduction strategy, or the noise reduction strategy can be adjusted based on the scene information. The embodiment of the present application does not limit the method for determining the target noise reduction strategy corresponding to the scene information.

[0047] Step 103: Send the target noise reduction strategy to the headset, so that the headset performs noise reduction according to the target noise reduction strategy.

[0048] It should be noted that after the target noise reduction strategy is determined, it is sent to the headset, and the headset can perform noise reduction according to the target noise reduction strategy. The method of using the electronic device to determine the target noise reduction strategy and then sending it to the headset for execution can avoid the headset from processing information itself, saving power consumption of the headset.

[0049] In the above method, the electronic device can automatically determine the target noise reduction strategy for headphone noise reduction according to the scene in which the headphone is located, thereby improving the accuracy of noise reduction strategy selection and being convenient for children to use.

[0050] In some embodiments, determining the scene information corresponding to the headset can be accomplished through interaction between the headset and an electronic device to reduce power consumption of the headset.

[0051] Acquiring the scene information corresponding to the headset in step 101 may include: receiving ambient sound information sent by the headset; acquiring location information of the electronic device; and acquiring the scene information corresponding to the headset based on the ambient sound information and the location information.

[0052] It should be noted that earphones are generally provided with microphones, and ambient sound information can be obtained through the earphones. Electronic devices such as wearable devices are generally provided with positioning modules such as GPS modules, and location information can be obtained through electronic devices. The earphones send the obtained ambient sound information to the electronic device, and the electronic device can determine the scene information corresponding to the current scene based on the ambient sound information and the location information.

[0053] For example, the ambient sound information may be subway sound, airplane landing sound, vehicle horn or human voice, etc., and the location information may be Zhonghua South Road, Line 11 Nanshan Station and Shenzhen Baoan Airport, etc. In a certain scene, when the received ambient sound is the sound of subway driving and the determined location information is the dynamic location information of the subway, the scene information may be determined to be on a certain subway line.

[0054] In some embodiments, the electronic device may be provided with noise reduction parameter requirements corresponding to the scene information, and the initial noise reduction strategy may be adjusted according to the noise reduction parameter requirements to obtain a target noise reduction strategy.

[0055] Figure 2 The following is a schematic diagram of an implementation flow of a method for determining a target noise reduction strategy provided in an embodiment of the present application. Figure 2 As shown, determining the target noise reduction strategy corresponding to the scene information in step 102 may include:

[0056] Step 1021: Determine the noise reduction parameter requirements corresponding to the scene information, the noise reduction parameter requirements include at least one of the noise reduction level requirements, the audio volume requirements and the audio retention requirements, the audio retention requirements are used to indicate the audio information that needs to be retained when performing noise reduction processing.

[0057] It should be noted that the electronic device may preset a correspondence between scene information and noise reduction parameter requirements. After obtaining the scene information, the corresponding noise reduction parameter requirements may be determined according to the scene information. The corresponding noise reduction parameter requirements are used to manage the noise reduction of the headphones in the current scene. For example, at least one of the noise reduction level requirements, audio volume requirements, and audio retention requirements may be set. Exemplarily, the noise reduction level requirement may include a constraint that the noise reduction level is higher or lower than a certain noise reduction level, the audio volume requirement may include a constraint that the volume is higher or lower than a certain volume level, and the audio retention requirement may include a constraint that a certain audio in the ambient sound needs to be retained during noise reduction processing. Exemplarily, the audio retention requirement may be to retain the audio of subway station announcements, parental calls, or car horns on the road.

[0058] It is understandable that the noise reduction parameter requirements can limit the setting of parameters in the noise reduction strategy. For example, parents can set the noise reduction parameter requirements to achieve the effect of protecting children when the headphones are used for noise reduction.

[0059] Step 1022: Adjust the initial noise reduction strategy according to the noise reduction parameter requirement to obtain a target noise reduction strategy.

[0060] It should be noted that the initial noise reduction strategy can be a default noise reduction strategy preset by the electronic device or headphones, or it can be a noise reduction strategy determined by the electronic device or headphones based on ambient sound information. The method for obtaining the initial noise reduction strategy is not limited here. After determining the noise reduction parameter requirements, the parameter requirements in the noise reduction parameter requirements can be compared with the current parameters in the initial noise reduction strategy. If the requirements are not met, the current parameters are adjusted according to the noise reduction parameter requirements to obtain the target noise reduction strategy. The embodiment of the present application does not limit the method for adjusting the initial noise reduction strategy according to the noise reduction parameter requirements to obtain the target noise reduction strategy.

[0061] In some embodiments, the noise reduction level of the headset can be adjusted according to scene information, and the noise reduction level should not change too much. Smooth changes can improve the performance of the headset and achieve higher resolution.

[0062] In an embodiment of the present application, the noise reduction parameter requirement may include a noise reduction level requirement, the initial noise reduction strategy includes a first noise reduction level, and adjusting the initial noise reduction strategy according to the noise reduction parameter requirement to obtain a target noise reduction strategy may include: when the first noise reduction level does not meet the noise reduction level requirement, adjusting the first noise reduction level to a second noise reduction level, the second noise reduction level meets the noise reduction level requirement, and the target noise reduction strategy includes the second noise reduction level.

[0063] For example, when the noise reduction level requirement on the subway is a noise reduction level range of 2-5, the first noise reduction level in the determined initial noise reduction strategy is level 7, which can be adjusted to the second noise reduction level, i.e., level 5, to achieve the determination of the noise reduction level according to the scene, and to smoothly adjust to a suitable noise reduction level to improve the resolution. The above method can be used to automatically adjust the noise reduction level, and realize noise reduction adaptive control.

[0064] In some embodiments, when the noise reduction level is insufficient, the headphones are more likely to increase the volume to cover up the residual noise, which may cause greater damage to hearing, so the volume needs to be controlled.

[0065] In an embodiment of the present application, the noise reduction parameter requirement may include an audio volume requirement, the initial noise reduction strategy includes a first volume level, and adjusting the initial noise reduction strategy according to the noise reduction parameter requirement to obtain a target noise reduction strategy may include: when the first volume level does not meet the audio volume requirement, adjusting the first volume level to a second volume level, the second volume level meets the audio volume requirement, and the target noise reduction strategy includes the second volume level.

[0066] For example, when the audio volume requirement on the subway is that the audio volume does not exceed level 6, the first volume level in the determined initial noise reduction strategy is level 7, which exceeds the audio volume requirement. It can be adjusted to the second volume level, i.e., level 6, to adjust the volume according to the scene and protect children's hearing. The above method can be used to automatically adjust the audio volume, realizing adaptive control of the volume.

[0067] In some embodiments, when noise reduction is turned on, important ambient sound information will be ignored, such as subway station announcements, car horns behind you, parents calling, your own speech, etc. For the safety of children, some audio can be set not to be noise-reduced.

[0068] In an embodiment of the present application, the noise reduction parameter requirement may include an audio retention requirement, and adjusting the initial noise reduction strategy according to the noise reduction parameter requirement to obtain a target noise reduction strategy may include: when the initial noise reduction strategy does not include first audio retention information, or when the initial noise reduction strategy includes the first audio retention information but the first audio retention information does not meet the audio retention requirement, determining that the audio retention information corresponding to the scene information is second audio retention information, and the target noise reduction strategy includes the second audio retention information.

[0069] For example, when the audio retention requirement on the subway is to retain the subway station announcement information, the determined initial noise reduction strategy does not include retaining the subway station announcement information, and it can be adjusted to retain the subway station announcement information, so as to determine the audio information that needs to be retained according to the scene, which is convenient for children to use. The above method can automatically adjust the audio information retention status, and realize the control of important information transparency.

[0070] Among them, there are many ways to achieve the audio retention requirement. For example, to retain the subway station announcement audio, you can collect the station announcement voice audio of each subway line in advance, perform voice analysis on the station announcement voice audio to determine the sound range, and retain the corresponding sound range when the headphone noise reduction is performed. For example, to retain the parent's call audio, you can collect the parent's speaking audio in advance to determine its sound range, and retain the corresponding sound range when the headphone noise reduction is performed. The embodiment of the present application does not limit the method for implementing the audio retention requirement.

[0071] In some embodiments, the noise reduction parameter requirements may be set according to scene requirements, or may be set by parents based on the child's situation.

[0072] In an embodiment of the present application, determining the noise reduction parameter requirement corresponding to the scene information may include: determining the noise reduction parameter requirement corresponding to the scene information according to a parameter setting rule, wherein the parameter setting rule is set by an associated electronic device corresponding to the electronic device.

[0073] It should be noted that when children use electronic devices, parents will monitor and manage the children's electronic devices through the associated electronic devices they use. For example, when a child uses a phone watch to control the noise reduction of headphones, the child's parents can use a smartphone to connect to the child's phone watch and set corresponding parameter setting rules for the noise reduction parameter requirements therein to achieve monitoring and management of the use of noise reduction headphones.

[0074] In some embodiments, after the electronic device determines the target noise reduction strategy, the target noise reduction strategy can be sent to an associated electronic device used by a parent, so that the parent can monitor the child's ear usage, etc.

[0075] Figure 3This is a schematic diagram of another implementation flow of a headphone noise reduction method provided in an embodiment of the present application. Figure 3 As shown, in Figure 1 Based on the illustrated embodiment, before sending the target noise reduction strategy to the headset, the method may further include:

[0076] Step 201: Send the target noise reduction strategy to an associated electronic device corresponding to the electronic device.

[0077] It should be noted that the electronic device sends the target noise reduction strategy to the associated electronic device corresponding to the electronic device, that is, the electronic device used, so that parents can monitor their children's ear usage through the App, set volume or usage time limits, etc., thereby improving the safety of children using noise-cancelling headphones.

[0078] In some embodiments, if the parent believes that the current noise reduction strategy of the headset is not suitable, the target noise reduction strategy can be adjusted through the associated electronic device to facilitate the parent's use.

[0079] Figure 4 A schematic diagram of the implementation flow of another headphone noise reduction method provided in an embodiment of the present application. Figure 4 As shown, in Figure 3 Based on the illustrated embodiment, after sending the target noise reduction strategy to an associated electronic device corresponding to the electronic device, the method may further include:

[0080] Step 202: receiving an adjustment instruction of the associated electronic device to the target noise reduction strategy.

[0081] For example, if a parent believes that the target noise reduction strategy of the current headphones is not suitable, the parent can modify the target noise reduction strategy through the App, such as setting volume or usage time limits, etc. The modification information can be generated by the App to generate an adjustment instruction and sent to the electronic device.

[0082] Step 203: adjusting the target noise reduction strategy according to the adjustment instruction to obtain an adjusted target noise reduction strategy.

[0083] It should be noted that, when the electronic device receives the adjustment instruction, it adjusts the target noise reduction strategy according to the adjustment instruction to obtain an adjusted target noise reduction strategy.

[0084] Accordingly, the step 103 of sending the target noise reduction strategy to the headset may include:

[0085] Step 204: Send the adjusted target noise reduction strategy to the headset, so that the headset performs noise reduction according to the adjusted target noise reduction strategy.

[0086] It should be noted that after the electronic device obtains the adjusted target noise reduction strategy, it is also necessary to send the adjusted target noise reduction strategy to the headset, so that the headset performs noise reduction according to the adjusted target noise reduction strategy.

[0087] The above method not only enables parents to monitor their children's ear usage, but also enables parents to adjust their children's ear usage in real time through associated electronic devices, which is convenient for parents to operate.

[0088] The following describes an exemplary application of the embodiments of the present application in a practical application scenario.

[0089] In an application scenario of the embodiment of the present application, two devices are included: an adaptive noise reduction headset and a children's phone watch. The main components of the headset are: processor, power supply, Bluetooth module, speaker, noise reduction module and microphone; the main components of the watch are: processor, power supply, Bluetooth module and positioning module.

[0090] Figure 5 This is the overall process of the headphone active noise reduction method provided in the embodiment of the present application. Figure 5 As shown, the method includes the following steps 301 to 304:

[0091] Step 301, the earphone and the watch are connected via Bluetooth, the earphone picks up the ambient sound information, the watch grabs the location information, and the earphone synchronizes the ambient sound information to the watch.

[0092] Step 302: The watch determines the scene by combining the real-time ambient sound information and the location information to obtain scene information. For example, the dynamic location information of the subway + the running sound of the subway determines that the user is on the subway.

[0093] Step 303: The watch provides a noise reduction adaptive strategy, a volume adaptive strategy and / or an audio retention strategy according to the scene information, that is, which types of ambient sounds are desired to be heard.

[0094] Step 304: The watch sends the determined noise reduction strategy, volume strategy and / or ambient sound retention strategy to the headset, and the headset dynamically adjusts the noise reduction level, volume and / or ambient sound. Parents can see the noise reduction strategy and set or modify related usage restrictions, which will also affect the final noise reduction level and volume.

[0095] In the above embodiment, through the cooperation of the functions of the watch and the earphones, the earphone usage scenario is efficiently identified, the appropriate noise reduction and volume adaptation strategy is used, and important information is communicated.

[0096] Figure 6 This is a flow chart of the active noise reduction scenario of headphones provided in the embodiment of the present application. Figure 6As shown, the electronic device obtains location information and ambient sound information, performs scene recognition based on the two information, obtains scene information, and performs adaptive noise reduction adjustment, adaptive volume adjustment, and important information transparency adjustment based on the scene information. Parents can monitor during this adjustment process.

[0097] The above adaptive method provides children with a way to ① complete the best noise reduction and volume adjustment to protect hearing without complicated operations or supervision; ② important information will be automatically transmitted to avoid unnecessary trouble in specific scenarios (missing the stop, car accidents); ③ parents can monitor the process to a certain extent, so that parents can feel more at ease with the safer headphone noise reduction method for their children.
