Referring to fig. 2, fig. 2 is a schematic flow chart of a noise reduction method for an earphone according to an embodiment of the present disclosure. The noise reduction method for the earphone is applied to the noise reduction earphone provided by the embodiment of the present application, as shown in fig. 2, the flow of the noise reduction method for the earphone provided by the embodiment of the present application may be as follows:
and 101, after communication connection with an external device is established, acquiring audio data of a current position.
It should be noted that the noise reduction earphone mentioned in the embodiments of the present application is an earphone with an active noise reduction function, and at least includes a processor, an audio output unit, and an audio acquisition unit, for example, the noise reduction earphone acquires external sound through the audio acquisition unit to obtain external audio data, then provides the acquired external audio data to the processor, generates a noise reduction audio data according to noise reduction parameters by the processor, and finally outputs the noise reduction audio data through the audio output unit to cancel external noise, thereby implementing active noise reduction.
For example, when the noise reduction earphone is a wired noise reduction earphone, a user can directly insert an earphone plug of the wired noise reduction earphone into an audio interface of the external device, so that wired communication connection is established between the wired noise reduction earphone and the external device; for another example, when the noise reduction earphone is a wireless noise reduction earphone, the user may operate the wireless noise reduction earphone to initiate a connection establishment request, and the external device responds to the connection establishment request to establish a wireless communication connection with the wireless noise reduction earphone.
Correspondingly, after the noise reduction earphone establishes communication connection with the external equipment, the audio data of the current position is acquired through the set audio acquisition unit.
And 102, identifying current scene information corresponding to the current position according to the audio data.
For example, after the noise reduction earphone acquires the audio data of the current position through the audio acquisition unit, the acquired audio data is provided to the processor, the processor identifies the current scene information of the current position according to a preset scene identification strategy, and the current scene information is used for describing the current scene corresponding to the current position of the noise reduction earphone.
And 103, acquiring own device information, and sending the device information and the current scene information to the external device.
After the current scene information corresponding to the current position is identified, the noise reduction earphone further acquires the own equipment information. The device information comprises manufacturer information, model information, processor information, audio output unit information and/or audio acquisition unit information of the noise reduction earphone.
After the device information of the noise reduction earphone is acquired, the noise reduction earphone is further connected with the external device through communication, and the acquired device information and the identified current scene information are sent to the external device together.
Illustratively, in the embodiment of the present application, a server is configured to maintain noise reduction parameters in a unified manner, and the server is provided with a noise reduction parameter library, where multiple sets of noise reduction parameters are stored in the noise reduction parameter library, and a correspondence between < device information, current scene information > and the noise reduction parameters is preset. The group of < device information, current scene information > may correspond to a plurality of 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.
The noise reduction earphone can generate a noise reduction parameter acquisition request according to a message format agreed with external equipment in advance, wherein the noise reduction parameter acquisition request carries the equipment information acquired by the noise reduction earphone and the identified current scene information; then, the generated noise reduction parameter acquisition request is transmitted to the external device through communication connection with the external device.
On the other hand, after receiving the noise reduction parameter acquisition request from the noise reduction earphone, the external device firstly identifies whether the noise reduction parameters which are simultaneously matched with the device information and the current scene information carried in the noise reduction parameter acquisition request are stored locally, if not, the noise reduction parameter acquisition request is sent to the server, the server is instructed to return the noise reduction parameters which are simultaneously matched with the device information and the current scene information carried in the noise reduction parameter acquisition request, and the noise reduction parameters are returned to the noise reduction earphone.
In addition, when the external device identifies that the noise reduction parameters matched with the device information and the current scene information are stored locally, the noise reduction parameters are directly returned to the noise reduction earphone.
And 104, receiving a noise reduction parameter which is returned by the external equipment and is matched with the equipment information and the current scene information at the same time, and loading the noise reduction parameter so as to carry out noise reduction processing according to the noise reduction parameter.
Correspondingly, the noise reduction earphone receives noise reduction parameters which are returned from the outside and are matched with the equipment information and the current scene information at the same time, and loads the noise reduction parameters, so that noise reduction processing can be carried out according to the noise reduction parameters.
The noise reduction earphone is used for configuring an audio output unit according to the acoustic EQ parameter, acquiring external audio data in real time through an audio acquisition unit, filtering the external audio data according to the noise reduction filter coefficient by a processor to generate noise reduction audio data, and playing the noise reduction audio data and audio data to be played from external equipment together, so that noise reduction playing is realized.
As can be seen from the above, in the embodiment of the present application, after the noise reduction earphone establishes a communication connection with an external device, the noise reduction earphone acquires audio data of a current location, determines current scene information corresponding to the current location according to the acquired audio data, further acquires device information of the noise reduction earphone, finally sends the acquired current scene information and device information to the external device, receives a noise reduction parameter, which is returned by the external device and is matched with the current scene information and the device information at the same time, and loads the noise reduction parameter, so that noise reduction is performed by using the noise reduction parameter. Therefore, the noise reduction earphone can acquire the noise reduction parameters matched with the actual scene and the hardware of the noise reduction earphone, noise can be reduced more flexibly, and the noise reduction effect can be improved.
In one embodiment, "identifying current scene information corresponding to a current location from audio data" includes:
(1) comparing the audio data with pre-stored sample audio data corresponding to different scene information;
(2) and determining scene information corresponding to the sample audio data matched with the audio data as current scene information.
In the embodiment of the application, sample audio data corresponding to different pieces of scene information are stored in the noise reduction earphone in advance, when the current scene information corresponding to the current position is identified according to the audio data, the noise reduction earphone compares the acquired audio data of the current position with the sample audio data corresponding to the plurality of pieces of scene information respectively, and determines the sample audio data matched with the audio data, so that the scene information corresponding to the sample audio data is determined as the current scene information corresponding to the current position.
The comparison between the audio data includes comparison between multiple dimensions, for example, in the embodiment of the present application, the comparison between the frequency spectrum dimension and the amplitude dimension is performed, so as to obtain the similarity between the audio data and the sample audio data in the frequency spectrum dimension and the similarity between the amplitude dimension, then the overall similarity between the audio data and the sample audio data is obtained by weighting according to the weights predefined in the frequency spectrum dimension and the amplitude dimension, and then, whether the similarity reaches the preset similarity is determined, if yes, it is determined that the audio data is matched with the sample audio data, otherwise, it is not matched.
In one embodiment, "identifying the current scene information corresponding to the current position according to the audio data" further includes:
(1) calling a pre-trained scene recognition model;
(2) and inputting the audio data into a scene recognition model for scene recognition to obtain current scene information corresponding to the current position.
It should be noted that, in the embodiment of the present application, a scene recognition model is also trained in advance.
For example, sample audio data of different scenes are collected firstly, a sample training set is constructed according to the collected sample audio data, then supervised training is carried out according to the sample training set by adopting a preset machine learning algorithm to obtain a scene recognition model, and then the trained scene recognition model is implanted into a noise reduction earphone.
Therefore, the noise reduction earphone can call a pre-trained scene recognition model when recognizing the current scene information corresponding to the current position according to the audio data, and then input the acquired audio data into the scene recognition model for scene recognition. The scene recognition model outputs a plurality of pieces of scene information possibly corresponding to the audio data and the probability corresponding to each piece of scene information, and correspondingly, the noise reduction earphone takes the scene information with the highest probability in the plurality of pieces of scene information output by the scene recognition model as the current scene information corresponding to the current position.

(2) and if the external equipment runs with the target application, acquiring the equipment information of the external equipment.
It should be noted that, in the embodiment of the present application, a corresponding relationship between a scene and an application that will normally run in the scene is also preset according to experience, for example, taking a commuting scene as an example, if a user would habitually run a news reading-type application through an external device to browse current news, the commuting scene would correspond to the news reading-type application.
Accordingly, the noise reduction headphone can verify the accuracy of scene recognition from the side by recognizing whether a connected external device is running a target application corresponding to current scene information.
The noise reduction earphone generates an application identification request according to a message format agreed with the external equipment, and sends the generated application identification request to the external equipment through communication connection with the external equipment to indicate the external equipment to identify whether the external equipment operates a target application corresponding to the current scene information.
On the other hand, after receiving the application identification request from the noise reduction earphone, the external device identifies whether the external device runs the target application, and returns the identification result.
Correspondingly, the noise reduction earphone receives an identification result returned by the external device, if the identification result is that the target application runs in the external application, the identified current scene information is judged to be accurate, and the self device information is further acquired at the moment; if the recognition result is that the external application does not run the target application, the recognized current scene information is judged to be possibly inaccurate, at the moment, the audio data is sent to the external equipment, the external equipment is instructed to recognize candidate current scene information corresponding to the current position according to the audio data, then, whether the candidate current scene information is consistent with the current scene information or not is judged, if yes, the recognized current scene information is judged to be accurate, and at the moment, the own equipment information is further obtained.
In one embodiment, "loading noise reduction parameters" includes:
and when the noise reduction parameters returned by the external equipment are multiple, loading the noise reduction parameters with the highest corresponding score in the multiple noise reduction parameters.
In the embodiment of the application, when the noise reduction parameters returned by the external device are multiple, the noise reduction earphone screens the noise reduction parameters with the highest corresponding score values from the multiple noise reduction parameters, and loads the noise reduction parameters as the optimal noise reduction parameters.
When the server historically sends the noise reduction parameters to other electronic devices, the score is obtained according to user scores fed back by the other electronic devices, for example, taking a certain noise reduction parameter as an example, the server may accumulate user scores returned by all other devices receiving the noise reduction parameter, and the accumulated sum is used as the score of the noise reduction parameter.
In an embodiment, before "sending the device information and the current context information to the external device", the method further includes:
(1) identifying whether noise reduction parameters matched with the equipment information and the current scene information are stored locally or not;
(2) and if the noise reduction parameters are not stored locally, sending the equipment information and the current scene information to external equipment.
The noise reduction earphone sends device information and current scene information to external equipment, firstly identifies whether noise reduction parameters matched with the device information and the current scene information are stored locally or not, and then sends the device information and the current scene information to the external equipment when the fact that the noise reduction parameters matched with the device information and the current scene information are not stored locally is identified, and the noise reduction parameters matched with the device information and the current scene information are obtained from the external equipment. Therefore, the noise reduction earphone can be prevented from repeatedly acquiring the noise reduction parameters.
In an embodiment, after "receiving the noise reduction parameters matched with the device information and the current scene information simultaneously returned by the external device", the method further includes:
and storing the noise reduction parameters which are returned by the external equipment and are matched with the equipment information and the current scene information at the same time according to a preset storage path.
In the embodiment of the application, after the noise reduction earphone receives the noise reduction parameters which are returned by the external equipment and are matched with the equipment information and the current scene information at the same time, the noise reduction parameters which are returned by the external equipment and are matched with the equipment information and the current scene information at the same time are stored according to the preset storage path, so that the noise reduction parameters can be directly obtained from the local place when needing to be obtained next time, and the noise reduction parameters do not need to be repeatedly obtained from the external equipment.
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.
