As shown in FIG. 1, FIG. 1 is a schematic diagram of a terminal structure of a hardware operating environment involved in a solution of an embodiment of the present application.

The step of receiving the target audio signal sent by other terminals and controlling the speaker to simultaneously output the target audio signal and the processed external audio signal includes:

Receiving the target audio signal sent by the other terminal;

Acquiring a second volume setting parameter of the earphone;

Determining the second volume according to the second volume setting parameter;

Referring to FIG. 2, in an embodiment of the method for controlling the earphone of the present application, the method for controlling the earphone includes the following steps:

Step S10: Obtain the external audio signal received by the microphone, and obtain the characteristic information of the external audio signal;

Step S20: Obtain processing parameters corresponding to the characteristic information;

Step S30: Process the external audio signal according to the processing parameters, and control the speaker to output the processed external audio signal.

In this embodiment, the earphone is provided with a microphone for receiving external sound waves and a speaker for playing the source signal. The microphone can receive external sound waves in real time and convert the external sound waves into external audio signals. Wherein, the external sound waves refer to sound waves other than the sound waves emitted by the speakers of the earphone in the environment where the earphone is located.

When the microphone receives the external audio signal, the external audio signal received by the microphone is acquired, and signal analysis is performed on the external audio signal to determine the characteristic information of the external audio signal.

Specifically, the external audio signal may be a time domain signal, a frequency domain signal or other transform domain signals. When the type of the external audio signal is different, the method of extracting the characteristic information of the external audio signal can also be different. Again, this embodiment does not specifically limit the manner of extracting the feature information of the external audio signal. For example, when the external audio signal is a time-domain signal, its characteristic information includes zero-crossing rate, short-term energy, short-term autocorrelation function, short-term average amplitude difference, and spectrogram (based on FFT (fast Fourier transform, fast Fourier transform)). Leaf transform)), short-term power spectral density, spectral entropy, fundamental frequency and/or formant and other sub-feature information.

When extracting each sub-feature information of the external audio signal, it can be based on different signal feature extraction algorithms, that is, based on the received external audio signal, one or more sub-feature information of the external audio signal can be extracted as the corresponding external audio signal. Characteristic information.

Further, when the feature information corresponding to the external audio signal is obtained, the corresponding processing parameter may be obtained based on the feature information.

Specifically, the headset is also provided with a scene audio feature database. When the feature information of the external audio signal is obtained, the feature information of the external audio signal can be queried in the scene audio feature database. The feature information of the signal matches the audio feature of the target scene. Among them, when querying the audio features of the target scene that matches the feature information of the external audio signal, the matching degree between the feature information of the external audio signal and the audio feature of each scene in the scene audio feature database can be obtained respectively, and then the external audio signal The matching degree between the feature information of each scene and the audio feature of each scene is sorted to determine the scene audio feature with the highest matching degree between the feature information of the external audio signal and the external audio signal in the scene audio feature database according to the sorting result. The audio feature of the scene with the highest matching degree between the feature information of the audio signal is taken as the audio feature of the target scene.

It is understandable that when the feature information includes multiple sub-feature information, in the process of calculating the matching degree between the feature information and any scene audio feature, the matching between each sub-feature information can be calculated one by one. As the sub-matching degree, after obtaining multiple sub-matching degrees, the weighted matching degree between the multiple sub-matching degrees can be used as the matching degree between the feature information and the audio feature of the scene, or multiple sub-matching degrees can be used. The average matching degree between the matching degrees is used as the matching degree between the feature information and the audio feature of the scene. Or, based on a plurality of sub-matching degrees, the degree of matching between the feature information and the audio feature of the scene is determined in another manner. Here, this embodiment does not make a specific limitation.

After the target scene audio feature corresponding to the feature information of the external audio signal is acquired, the preset processing parameter associated with the target scene audio feature can be acquired as the processing parameter corresponding to the feature information. Wherein, the preset processing parameter is a preset value stored in the earphone in association with the audio feature of the target scene in advance.

Further, the earphone is also provided with an equalizer. After obtaining the processing parameters, the equalizer can be controlled to process the external audio signal according to the processing parameters, and then use the processed external audio signal as the speaker Source signal to output the processed external audio signal.

Specifically, after the processing parameters are obtained, the operating parameters of the equalizer can be set according to the processing parameters, and then the external audio signal received by the microphone is used as the input signal of the equalizer, so that the missed signal received by the microphone can be detected by the equalizer. The audio signal is equalized for the full frequency band. The output signal of the equalizer (that is, the processed external audio signal) is used as the source signal of the speaker, and the speaker is controlled to emit sound waves to achieve the purpose of outputting the processed external audio signal through the speaker.

It is understandable that different scene audio features are associated with different processing parameters, and the processing parameters are processing parameters set in advance according to the sound wave characteristics corresponding to the scene. After the external audio signal is equalized according to the processing parameters, the key points in the external audio signal can be more emphasized, and the interference factors in the voice can be reduced. For example, to listen to music in a quiet environment, the full frequency band that needs to be monitored needs to be increased to notice the sudden situation around; in a noisy environment, the full frequency band that needs to be monitored is adjusted to the lowest level, so you can enjoy music with peace of mind; in the case of driving, Need to pay attention to the outside sound, suppress tire noise or wind noise, need to monitor to turn on the high-pass mode.

Optionally, before the step S10, the earphone may first detect whether the monitoring function has been turned on at the current moment, and when the earphone has turned on the monitoring function, steps S10 to S30 are executed. No response, that is, neither processing nor playing the external audio signal. Wherein, the monitoring function can be turned on through a control control set on the earphone, or it may be turned on through other methods.

In the technical solution disclosed in this embodiment, the external audio signal received by the microphone is first acquired, and the characteristic information of the external audio signal is acquired, and then the processing parameter corresponding to the characteristic information is acquired to process the external audio signal according to the processing parameter. , And control the speaker to output the processed external audio signal. Since the external audio signal can be received through the microphone, the corresponding processing parameters can be determined according to the received external audio signal, and the external audio signal processed based on the processing parameters can be broadcast, so that the user can receive external sound waves through the headset when using the headset. And the sound wave corresponding to the external audio signal emitted by the earphone is the sound wave pre-processed by the earphone based on the scene parameters, which achieves the effect of improving the compatibility of the earphone for different usage scenarios without affecting the use effect of the earphone.

Optionally, referring to FIG. 3, based on the foregoing embodiment, in another embodiment, the method for controlling the headset further includes the following steps:

Step S40: Receive a target audio signal sent by another terminal, and control the speaker to simultaneously output the target audio signal and the processed external audio signal.

It needs to be stated that the step execution flow of an optional embodiment shown in FIG. 3 is not used to limit this application, and step S40 is only fixedly executed after step S30.

In this embodiment, the earphone is further provided with a connection module, and the connection module may include a wired connector and/or a wireless communication component. When the wired connector is connected to other terminals, and/or the wireless communication component establishes a connection with other terminals, the earphone can receive the target audio signal sent by the other terminal. For example, it can be an audio signal of a multimedia file.

After the earphone receives the target audio signal, the target audio signal and the processed external audio signal can be used as the source signal of the speaker at the same time, so as to control the speaker to simultaneously output the target audio signal and the processed external audio signal.

Optionally, before performing step S40, a first volume and a second volume may be determined first, where the first volume is the output volume of the target audio signal, and the second volume is the processed volume. The output volume of the external audio signal. Then control the speaker to output the target audio signal according to the first volume, and output the processed external audio signal according to the second volume.

Specifically, a volume adjustment component is provided on the earphone, wherein the volume adjustment component includes a volume adjustment control. The user can adjust the playback volume of the headset by triggering the volume adjustment control. And/or the headset can also receive volume setting parameters sent by other terminals.

It is understandable that the volume adjustment control can be set as a physical button or a physical knob. Among them, the push-type physical key can be triggered by pressing, the sliding-type physical key can be triggered by sliding, or the knob can be triggered by rotating. The volume adjustment control can also be set as a virtual touch button, which can be triggered by a touch operation. The volume adjustment control can also be set as a voice control or gesture control volume adjustment control.

Optionally, the earphone may obtain and receive the first volume setting parameter sent by other terminals, and/or obtain the second volume setting parameter set by the user through the volume adjustment device. Then the first volume is determined according to the first volume setting parameter and/or the second volume setting parameter. Then, after the first volume is determined, the second volume is determined according to the first volume. Wherein, when the second volume is determined according to the first volume, the volume increase parameter may be acquired first. The volume increase parameter may be a proportional value, so that after the first volume is adjusted according to the ratio, the adjusted first volume can be used as the second volume. Or the volume increase parameter may be a fixed value, so that the first volume can be adjusted according to the fixed value, and the adjusted first volume can be used as the second volume.

Exemplarily, after the first volume A is determined according to the first volume setting parameter and/or the second volume setting parameter, the increase parameter m% may be obtained, and then Am% is used as the second volume. Or get the increase parameter n, and then use A+n as the second volume.

It can be understood that, in order to make the second volume greater than or equal to the first volume, the volume increase parameter m% may be set to be greater than or equal to 100%, or the volume increase parameter n may be set to be greater than or equal to zero.

Optionally, when determining the first volume and the second volume, the set volume of the earphone may be determined first according to the second volume setting parameter set by the user, and the set volume of the earphone is used as the second volume. Then the first volume is determined according to the second volume.

Wherein, when determining the first volume according to the second volume, the volume attenuation parameter may be acquired first, and then the first volume is determined according to the volume attenuation parameter and the second volume.

Exemplarily, when the second volume is B, the volume attenuation parameter x% or y can be obtained, and then Bx% or B-y is used as the first volume. It can be understood that, in order to make the second volume greater than or equal to the first volume, the volume adjustment parameter x% may be set to be less than or equal to 100%, or the volume adjustment parameter y may be set to be greater than or equal to zero.
