It should be noted that the scene schematic diagram of the headphone noise reduction method shown in fig. 1 is only an example, and the scene of the headphone noise reduction method described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not form a limitation to the technical solution provided in the embodiment of the present application.
Referring to fig. 2, fig. 2 is a schematic flowchart of a noise reduction method for an earphone according to an embodiment of the present disclosure. The method for reducing noise of the earphone is applied to the electronic device provided by the embodiment of the present application, as shown in fig. 2, the flow of the method for reducing noise of the earphone provided by the embodiment of the present application may be as follows:
101, after establishing communication connection with the earphone, acquiring the equipment information of the earphone.
It should be noted that the earphone mentioned in the embodiments of the present application is an earphone with an active noise reduction function, which at least includes a processor and an audio output unit, for example, the processor can generate an audio signal in anti-phase with the noise signal through the noise reduction parameter, so that the audio signal is output through the audio output unit to cancel the noise signal, thereby implementing active noise reduction.
For example, when the earphone is a wired earphone, a user can directly insert an earphone plug of the wired earphone into an audio interface of the electronic device, and the electronic device establishes wired communication connection with the wired earphone; for another example, when the headset is a wireless headset, the user may operate the wireless headset to initiate a connection establishment request, and the electronic device responds to the connection establishment request to establish a wireless communication connection with the wireless headset.
Correspondingly, after the electronic device establishes communication connection with the headset, the electronic device sends a device information acquisition request to the headset, wherein the device information acquisition request is used for indicating the headset to return the device information thereof.
On the other hand, after receiving the device information acquisition request of the electronic device, the headset returns the device information of the headset to the electronic device according to the device information acquisition request.
Wherein the device information includes manufacturer information, model information, processor information, and/or audio output unit information of the headset.
And 102, acquiring the position information of the current position, and determining scene information corresponding to the current position according to the position information.
The electronic equipment also acquires the position information of the current position, wherein the position information comprises longitude/latitude coordinates and is used for describing the current position. The electronic equipment comprises a satellite positioning component, a base station positioning component and a short-distance wireless positioning component.
The satellite positioning component realizes positioning by adopting satellite positioning technologies such as GPS, beidou, glonass and/or Galileo.
The base station positioning component realizes positioning by adopting the base station positioning technology such as LBS and the like.
The short-distance wireless positioning component realizes positioning by adopting short-distance wireless positioning technologies such as Wi-Fi positioning, UWB triangulation positioning, bluetooth positioning and the like.
When the position information of the current position cannot be obtained through the positioning of the satellite positioning component (for example, when the electronic equipment is located in an environment where satellite positioning signals such as indoor and the like are shielded, the satellite positioning component cannot perform positioning), the electronic equipment obtains the position information of the current position through the cooperative positioning of the base station positioning component and the short-distance wireless positioning component so as to ensure the accuracy of the position information.
It should be noted that, in the embodiment of the present application, a corresponding relationship between position information and scene information is set in advance in an electronic device, and is used to describe scenes corresponding to different positions, for example, a position information describes a position a, and i scene information corresponding to the position a describes an i scene, that is, it indicates that a scene corresponding to the position a is an i scene. The corresponding relationship between the position information and the scene information may be in the form of a scene comparison table, as shown in the following table:
| position information A, position information B, and position information C | i scene information |
| D position information | j scene information and k scene information |
| E position information | Information of l scene |
It can be seen that, in the embodiment of the present application, multiple pieces of location information may correspond to the same piece of scene information, the same piece of location information may correspond to multiple pieces of scene information, and one piece of location information may correspond to one piece of location information.
And 103, acquiring noise reduction parameters matched with the device information and the scene information.
Wherein the noise reduction parameters include noise reduction filter parameters and acoustic EQ parameters. After acquiring the device information of the headset with the established communication connection and acquiring the scene information corresponding to the current position, the electronic device further acquires noise reduction parameters matched with the device information and the scene information, for example, acquires the noise reduction parameters with the highest degree of matching with the device information and the scene information.
And 104, providing the noise reduction parameters to the earphone, and instructing the earphone to carry out noise reduction processing according to the noise reduction parameters.
After the noise reduction parameters which are simultaneously matched with the device information and the scene information are acquired, the electronic device provides the noise reduction parameters for the earphone through the communication connection between the electronic device and the earphone, and instructs the earphone to perform noise reduction processing according to the noise reduction parameters.
On the other hand, after receiving the noise reduction parameters provided by the electronic device, the headset loads the noise reduction parameters and performs noise reduction processing according to the noise reduction parameters. The noise reduction earphone is characterized in that the noise reduction earphone firstly configures the audio output unit according to the acoustic EQ parameters, then external audio data are collected in real time through the audio collection unit, the external audio data are filtered by the processor according to the noise reduction filter coefficient to generate noise reduction audio data, and the noise reduction audio data and audio data to be played from external equipment are played together, so that noise reduction playing is achieved, and the optimal noise reduction playing effect is obtained.
As can be seen from the above, in the embodiment of the present application, after the communication connection is established with the headset, the device information of the headset is obtained; then obtaining the position information of the current position, and determining scene information corresponding to the current position according to the position information; then, noise reduction parameters matched with the equipment information and the scene information are obtained; and finally, providing the noise reduction parameters for the earphone, and indicating the earphone to perform noise reduction processing according to the noise reduction parameters. Therefore, the earphone can acquire the noise reduction parameters matched with the actual scene and the hardware of the earphone, not only can the noise be reduced more flexibly, but also the noise reduction effect can be improved.
In one embodiment, "acquiring the noise reduction parameters matched with the device information and the scene information" includes:
(1) Sending the equipment information and the scene information to a server;
(2) Receiving noise reduction parameters matched with the equipment information and the scene information returned by the server;
when the server has a plurality of noise reduction parameters matched with the equipment information and the scene information, the server returns the noise reduction parameters with the highest corresponding score values in the plurality of noise reduction parameters.
It should be noted that in the embodiment of the present application, a server is configured to maintain noise reduction parameters in a unified manner, where the server is provided with a noise reduction parameter library, and multiple sets of noise reduction parameters are stored in the noise reduction parameter library, and a correspondence between < device information, scene information > and noise reduction parameters is preset. The group of < device information, scene information > may correspond to multiple groups of noise reduction parameters, or may correspond to a group of noise reduction parameters, which may be specifically set by a person skilled in the art according to actual needs.
For example, for a certain headphone, a general noise reduction parameter suitable for the headphone to perform noise reduction processing may be generated in advance, and then, the general noise reduction parameter is adaptively adjusted according to different scenes, so as to obtain a noise reduction parameter suitable for the headphone to perform noise reduction in different scenes.
In the embodiment of the application, when the electronic device acquires the noise reduction parameters matched with the device information and the scene information, the electronic device may generate a noise reduction parameter acquisition request according to a message format agreed with a server in advance, wherein the noise reduction parameter acquisition request carries the device information and the scene information acquired by the electronic device; and then, sending the generated noise reduction parameter acquisition request to a server, and indicating the server to return noise reduction parameters which are matched with the device information and the scene information carried in the noise reduction parameter acquisition request at the same time.
On the other hand, after receiving the noise reduction parameter acquisition request from the electronic device, the server analyzes the device information and the scene information carried by the noise reduction parameter acquisition request, searches for the noise reduction parameter simultaneously matched with the analyzed device information and scene information according to the preset corresponding relation between the < device information, scene information > and the noise reduction parameter, and returns the noise reduction parameter to the electronic device.
Correspondingly, the electronic device receiving server obtains the noise reduction parameters returned by the request according to the noise reduction parameters, namely the noise reduction parameters which are simultaneously matched with the device information of the earphone and the scene information of the current position, namely the noise reduction parameters suitable for noise reduction of the earphone in the scene corresponding to the current position.
In addition, when the server returns the noise reduction parameter value to the electronic device, if a plurality of noise reduction parameters with which the device information and the scene information are simultaneously matched exist, the noise reduction parameters with the highest corresponding score values are screened from the plurality of noise reduction parameters, and the noise reduction parameters are returned to the electronic device as the optimal noise reduction parameters.
In addition, the server may further update the noise reduction parameter of which the score reaches a preset score, where a value of the preset score is not specifically limited in the embodiment of the present application and may be taken by a person of ordinary skill in the art according to actual needs.
For example, taking a noise reduction parameter as an example, the server may accumulate user scores returned by all other devices receiving the noise reduction parameter, and use the accumulated sum as the score of the noise reduction parameter.

(1) Identifying whether noise reduction parameters matched with the equipment information and the scene information are stored locally;
(2) And when the noise reduction parameters matched with the equipment information and the scene information are not stored locally, sending the equipment information and the scene information to a server.

Therefore, the electronic equipment can be prevented from repeatedly downloading the noise reduction parameters, and the flow consumption is saved.
In an embodiment, after "receiving the noise reduction parameters matched with the device information and the scene information returned by the server", the method further includes:
and storing the noise reduction parameters matched with the equipment information and the scene information returned by the server according to a preset storage path.

It should be noted that, in the embodiment of the present application, the setting of the preset storage path is not specifically limited, and may be set by a person skilled in the art according to actual needs.

In the embodiment of the application, after the electronic device acquires the noise reduction parameters which are simultaneously matched with the device information and the scene information, according to a preset plug-in generation rule matched with the earphone (namely, the earphone which is in communication connection with the electronic device), the electronic device generates the corresponding noise reduction plug-in according to the acquired noise reduction parameters. Then, the electronic device provides the generated noise reduction plug-in to the earphone through the communication connection between the electronic device and the earphone, and instructs the earphone to load the noise reduction plug-in.
On the other hand, after the earphone receives the noise reduction plug-in provided by the electronic device, the noise reduction plug-in is loaded according to the indication of the electronic device, so that the noise reduction processing can be performed according to the noise reduction plug-in to obtain the optimal noise reduction effect.

Accordingly, the electronic device can verify the accuracy of the acquired scene information from the side through the running application. The electronic device identifies whether a target application corresponding to a scene described by the acquired scene information is currently running according to a corresponding relationship between the scene and the application, determines that the acquired scene information is accurate if the target application is currently running, and further acquires a noise reduction parameter matched with the device information and the scene information at this time to provide the noise reduction parameter for the earphone to perform noise reduction processing.

201, after establishing communication connection with the headset, the electronic device acquires device information of the headset.
It should be noted that the earphone mentioned in the embodiments of the present application is an earphone with an active noise reduction function, and includes at least a processor and an audio output unit, for example, the processor can generate an audio signal in an anti-phase with a noise signal through a noise reduction parameter, so that the audio signal is output through the audio output unit to cancel the noise signal, thereby implementing active noise reduction.
For example, when the earphone is a wired earphone, a user can directly insert an earphone plug of the wired earphone into an audio interface of the electronic device, and the electronic device establishes a wired communication connection with the wired earphone; for another example, when the headset is a wireless headset, the user may operate the wireless headset to initiate a connection establishment request, and the electronic device may respond to the connection establishment request to establish a wireless communication connection with the wireless headset.
Correspondingly, after the electronic device establishes communication connection with the earphone, a device information acquisition request is sent to the earphone, and the device information acquisition request is used for indicating the earphone to return the device information.
On the other hand, after receiving the device information acquisition request of the electronic device, the headset returns the device information of the headset to the electronic device according to the device information acquisition request.
Wherein the device information includes manufacturer information, model information, processor information, and/or audio output unit information of the headset.

The electronic equipment also acquires the position information of the current position, wherein the position information comprises longitude/latitude coordinates and is used for describing the current position. The electronic equipment comprises a satellite positioning component, a base station positioning component and a short-distance wireless positioning component.
The satellite positioning component realizes positioning by adopting satellite positioning technologies such as GPS, beidou, glonass and/or Galileo.
The base station positioning component realizes positioning by adopting the base station positioning technology such as LBS and the like.
The short-distance wireless positioning component realizes positioning by adopting short-distance wireless positioning technologies such as Wi-Fi positioning, UWB triangulation positioning, bluetooth positioning and the like.
When the position information of the current position cannot be obtained through the positioning of the satellite positioning component (for example, when the electronic equipment is located in an environment where satellite positioning signals such as indoor and the like are shielded, the satellite positioning component cannot perform positioning), the electronic equipment obtains the position information of the current position through the cooperative positioning of the base station positioning component and the short-distance wireless positioning component so as to ensure the accuracy of the position information.
It should be noted that, in the embodiment of the present application, a corresponding relationship between position information and scene information is set in advance in an electronic device, and is used to describe scenes corresponding to different positions, for example, a position information describes a position a, and i scene information corresponding to the position a describes an i scene, that is, it indicates that a scene corresponding to the position a is an i scene. The corresponding relationship between the position information and the scene information may be in the form of a scene comparison table, as shown in the following table:
| position information A, position information B, and position information C | i scene information |
| D position information | j scene information and k scene information |
| E position information | Information of l scene |

The group of < device information, scene information > may correspond to multiple groups of noise reduction parameters, or may correspond to a group of noise reduction parameters, which may be specifically set by a person skilled in the art according to actual needs.
For example, for a certain headphone, a general noise reduction parameter suitable for the headphone to perform noise reduction processing may be generated in advance, and then, for different scenes, the general noise reduction parameter is adaptively adjusted to obtain a noise reduction parameter suitable for the headphone to perform noise reduction in different scenes.
In the embodiment of the application, when the electronic device acquires the noise reduction parameters matched with the device information and the scene information, the electronic device may generate a noise reduction parameter acquisition request according to a message format agreed with a server in advance, where the noise reduction parameter acquisition request carries the device information and the scene information acquired by the electronic device; and then, sending the generated noise reduction parameter acquisition request to a server, and indicating the server to return noise reduction parameters which are matched with the device information and the scene information carried in the noise reduction parameter acquisition request at the same time.
204, the electronic device receives the noise reduction parameters matched with the device information and the scene information returned by the server, wherein the server returns the noise reduction parameters with the highest corresponding score values in the noise reduction parameters when the noise reduction parameters matched with the device information and the scene information are multiple.
On the other hand, after receiving the noise reduction parameter acquisition request from the electronic device, the server analyzes the device information and the scene information carried by the noise reduction parameter acquisition request, finds the noise reduction parameter simultaneously matched with the analyzed device information and scene information according to the preset corresponding relationship between the < device information, scene information > and the noise reduction parameter, and returns the noise reduction parameter to the electronic device.
