Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Currently, earphone devices are used to output audio signals to a user and to receive audio signals input by the user. When the user is in a specific motion state (such as riding), the user needs to acquire wind speed information to adjust the activity state.

In the related art, the earphone can only identify wind noise through the collected microphone signals, and then the influence of noise is reduced by adopting a preset noise suppression mode, the wind speed information cannot be determined, the requirement of a user for acquiring the wind speed information is difficult to meet, and therefore the use experience of the user is influenced.

In order to solve the above technical problems, the present disclosure provides a wind speed determination method, which determines a first energy parameter of a first microphone outside an ear canal and a second energy parameter of a second microphone inside the ear canal according to a first microphone signal of the first microphone outside the ear canal and a second microphone signal of the second microphone inside the ear canal, respectively. By comparing the first energy parameter and the second energy parameter, the wind speed information of the environment where the earphone is located can be determined, and the function of determining the wind speed information by the earphone is realized so as to improve the use experience of a user.

For ease of understanding, the earphone device of the present disclosure will be described first. As shown in fig. 1, the earphone device comprises a first earphone 1 and/or a second earphone 2. The first earphone 1 may be located in the left ear and the second earphone 2 may be located in the right ear. Or the first earphone 1 may be located in the right ear and the second earphone 2 may be located in the left ear. The first earphone 1 and/or the second earphone 2 comprises a first microphone 11 located outside the ear canal and a second microphone 12 located inside the ear canal. The first microphone 11 is usually located at the ear stem position, either at the end or in the middle. The second microphone 12 is typically located around the earmuff. In the process of acquiring the wind noise signal, the first microphone 11 can acquire the wind noise signal of each frequency band. The second microphone 12 is capable of collecting low frequency wind noise signals, which are absorbed by the user. Under different wind speed information, the wind noise signals received by the first microphone 11 and the second microphone 12 have different differences, so that the determination of the wind speed information is realized. In an embodiment, the first earphone 1 and/or the second earphone 2 further comprise a third microphone located outside the ear canal. When the first microphone 11 is located at the end of the ear stem position, the third microphone is located in the middle of the ear stem position. When the first microphone 11 is located in the middle of the ear stem position, the third microphone is located at the end of the ear stem position. The first microphone 11 may be a talk microphone or a feed-forward microphone, for example. The second microphone 12 is a feed-back microphone. Wherein the feedforward microphone and the feedforward microphone are used for active noise reduction. The communication microphone can be independently used for communication noise reduction, and can also be used for noise reduction together with the feedforward microphone and the feedback microphone to improve the effect of communication noise reduction.

The embodiment of the disclosure provides a wind speed determining method applied to a first earphone, wherein the first earphone comprises a first microphone positioned outside an ear canal in a wearing state and a second microphone positioned in the ear canal in the wearing state, as shown in fig. 2, and the method comprises the following steps:

S100, acquiring a first microphone signal acquired by a first microphone and a second microphone signal acquired by a second microphone.

S200, determining a first energy parameter according to the first microphone signal.

S300, determining a second energy parameter according to the second microphone signal.

S400, comparing the first energy parameter with the second energy parameter, and determining wind speed information according to the comparison result.

In this embodiment, the first energy parameter of the first microphone outside the ear canal and the second energy parameter of the second microphone inside the ear canal are determined according to the first microphone signal of the first microphone outside the ear canal and the second microphone signal of the second microphone inside the ear canal, respectively. By comparing the first energy parameter and the second energy parameter, the wind speed information of the environment where the earphone is located can be determined, and the function of determining the wind speed information by the earphone is realized so as to improve the use experience of a user.

In one embodiment, as shown in fig. 3, the determining the first energy parameter according to the first microphone signal in step S200 is determined by:

S210, determining a first time domain relation between time and amplitude of the first microphone signal according to the first microphone signal.

S220, converting the first time domain relation to obtain a first frequency domain relation between the frequency and the energy of the first microphone signal.

S230, determining a first energy parameter according to the first frequency domain relation.

In this embodiment, after receiving the first microphone signal, the first microphone signal is used as the first time domain relationship according to the change relationship of the amplitude with time. Since the first energy parameter is required to determine the wind speed information, the first time domain relationship is converted into the energy-to-frequency variation relationship as the first frequency domain relationship. According to the first frequency domain relation, energy of a required frequency range is selected as a first energy parameter. The first time domain relation is converted into the first frequency domain relation, so that the first energy parameter is extracted from the first microphone signal to determine the wind speed information, and the reliability of wind speed information determination is improved.

In an embodiment, the first microphone is an analog microphone, as shown in fig. 4, the first time-domain relationship between the time and the amplitude of the first microphone signal is determined in step S210 according to the first microphone signal by the following manner:

S211, converting the first microphone signal into a first digital audio signal.

S212, determining a first time domain relation between the time and the amplitude of the first microphone signal according to the first digital audio signal.

In this embodiment, when the first microphone is an analog microphone, the earphone cannot directly process the first microphone signal, and the first microphone signal needs to be converted into a first digital audio signal that can be identified by the earphone. A first time domain relationship of time and amplitude in the first microphone signal is determined from the first digital audio signal. The unrecognizable analog signal is converted into a digital signal, so that the earphone can process the first microphone signal, and reliability of wind speed information determination is improved.

Illustratively, the converting the first time-domain relationship in step S220 to obtain the first frequency-domain relationship between the frequency and the energy of the first microphone signal may be implemented by means of fourier transform.

In one embodiment, as shown in fig. 5, the determining the first energy parameter according to the first frequency domain relation in step S230 is determined by:

s231, integrating the energy lower than the first preset frequency in the first frequency domain relation.

S232, determining the integration result as a first energy parameter.

In this embodiment, since the first microphone is located outside the ear canal and can collect the full-band signal, the second microphone is located inside the ear canal and can collect only the low-frequency signal, and the comparison between the first energy parameter and the second energy parameter is required. Therefore, it is necessary to extract low frequency energy in the first microphone signal. Integrating the energy lower than the first preset frequency in the first frequency domain relation, calculating the area of the energy in the low-frequency signal, and taking the area as a first energy parameter. And the first energy parameter is determined by selecting low-frequency energy for integration so as to improve the reliability of wind speed information determination.

For example, the first preset frequency may be selected by referring to a frequency band signal of the wind noise signal, where the frequency band signal is high in energy and not easy to be absorbed by a user. For example, 600Hz, 800Hz, 1kHz, etc.

In one embodiment, as shown in fig. 6, the determining the second energy parameter according to the second microphone signal in step S300 is determined by:

s310, determining a second time domain relation between time and amplitude of the second microphone signal according to the second microphone signal.

S320, converting the second time domain relation to obtain a second frequency domain relation of the frequency and the energy of the second microphone signal.

S330, determining a second energy parameter according to the second frequency domain relation.

In this embodiment, after receiving the second microphone signal, the second microphone signal is used as the second time-domain relationship according to the change relationship of the amplitude with time. Since a second energy parameter is required to determine the wind speed information, the second time domain relationship is converted into a variation relationship of energy with frequency as a second frequency domain relationship. According to the second frequency domain relation, energy of the required frequency range is selected as a second energy parameter. The second time domain relation is converted into the second frequency domain relation, so that the second energy parameter is extracted from the second microphone signal to determine the wind speed information, and the reliability of wind speed information determination is improved.

In an embodiment, the second microphone is an analog microphone, as shown in fig. 7, the second time-domain relationship between the time and the amplitude of the second microphone signal is determined according to the second microphone signal in step S310 by the following method:

s311, converting the second microphone signal into a second digital audio signal.

S312, determining a second time domain relation between the time and the amplitude of the second microphone signal according to the second digital audio signal.

In this embodiment, when the second microphone is an analog microphone, the earphone cannot directly process the second microphone signal, and the second microphone signal needs to be converted into a second digital audio signal that can be recognized by the earphone. And determining a second time domain relation between time and amplitude in the second microphone signal according to the second digital audio signal. The second microphone signal can be processed by the earphone by converting the unidentifiable analog signal into a digital signal, so that the reliability of wind speed information determination is improved.

Illustratively, the converting the second time-domain relationship in step S320 to obtain the second frequency-domain relationship between the frequency and the energy of the second microphone signal may be implemented by means of fourier transform.

In one embodiment, as shown in fig. 8, the determining the second energy parameter according to the second frequency domain relation in step S330 is determined by:

s331, integrating the energy lower than a second preset frequency in the second frequency domain relation.

And S332, determining the integration result as a second energy parameter.

In this embodiment, since the first microphone is located outside the ear canal and can collect the full-band signal, the second microphone is located inside the ear canal and can collect only the low-frequency signal, and the comparison between the first energy parameter and the second energy parameter is required. Therefore, it is necessary to extract low frequency energy in the second microphone signal. And integrating the energy lower than a second preset frequency in the second frequency domain relation, and obtaining the area of the energy in the low-frequency signal, wherein the area is used as a second energy parameter. And the second energy parameter is determined by selecting low-frequency energy for integration so as to improve the reliability of wind speed information determination.

For example, the second preset frequency may be selected by referring to a frequency band signal of the wind noise signal, which has high energy and is not easily absorbed by the user. For example, 600Hz, 800Hz, 1kHz, etc.

In one embodiment, as shown in fig. 9, the determining wind speed information in step S400 according to the first energy parameter and the second energy parameter is determined by:

S410, determining an energy difference value of the first energy parameter and the second energy parameter.

S420, determining preset configuration information, wherein the preset configuration information is used for representing the corresponding relation between the preset energy difference value and the wind speed information.

S430, determining wind speed information based on preset configuration information and the energy difference value.

In this embodiment, since the difference between the first energy parameter and the second energy parameter is different under different wind speed information, the energy difference between the first energy parameter and the second energy parameter is determined to determine the magnitude of the difference. And determining preset configuration information corresponding to the preset energy difference value and the wind speed information, and taking the preset configuration information as a reference for determining the wind speed information by a table look-up method. And determining wind speed information corresponding to the energy difference value in the preset configuration information based on the preset configuration information and the energy difference value. By determining the wind speed information corresponding to the energy difference value in a table look-up mode, the accuracy of determining the wind speed information is improved.

For example, the determining the preset configuration information in step S420 may be performed by measuring different energy differences under different wind speed information in advance, and establishing a correspondence between the energy differences and the wind speed information. The energy difference values under different wind speed information can be deduced according to a theoretical deduction mode, and the corresponding relation between the energy difference values and the wind speed information is established. The theoretical deduction result can be corrected by combining with the actual test on the basis of theoretical deduction, and the corresponding relation between the energy difference value and wind speed information is established.

In one embodiment, the greater the absolute value of the energy difference, the greater the wind speed information. The smaller the absolute value of the energy difference, the smaller the wind speed information.

In the present embodiment, in the case where the wind speed information is small, the low frequency energy received by the first microphone and the second microphone is small, and the energy difference value thereof is small. As the wind speed information increases gradually, the low frequency energy received by the first microphone and the second microphone increases gradually, and the increasing speeds are different. In the case where the wind speed information is large, the energy difference value between the first microphone and the second microphone is large. The wind speed information is determined to be small under the condition that the energy difference value is small, and the wind speed information is determined to be large under the condition that the energy difference value is large, so that the energy difference value can accurately reflect the size of the wind speed information to improve the accuracy of wind speed information determination.

The wind speed determining method provided by an embodiment of the present disclosure further includes the following steps:

And sending wind speed prompt information to a user according to the wind speed information.

In the embodiment, after the wind speed information is determined, the wind speed prompt information is sent to the user to enable the user to acquire the wind speed information, so that the user can adjust the movement according to the wind speed information, and the use experience of the user is improved.

Illustratively, according to the wind speed information, a wind speed prompt message is sent to the user, and the wind speed information can be played to the user by the first earphone. The first earphone may send the wind speed information to the electronic device of the user, and the user obtains the wind speed information through the electronic device. The electronic device is, for example, a mobile phone, a notebook computer, a tablet computer, a wearable device, etc.

and adopting a wind noise suppression strategy corresponding to the wind speed information according to the wind speed information.

In this embodiment, the wind noise information may interfere with the audio signal input to the earphone by the user under different wind speed information. According to the wind speed information, the corresponding wind noise suppression strategy is adopted to reduce the interference of the audio signal input, so that the call quality of a user is improved.

For example, the wind noise suppression strategy may be to adjust the gain of the first microphone according to the magnitude of the wind speed information. The low-frequency band signal collected by the first microphone can be adjusted according to the wind speed information.

As shown in fig. 10, the wind speed determining method provided in an embodiment of the present disclosure further includes the following steps:

S510, according to the movement speed information and the wind speed information, safety prompt information is sent to a user.

In this embodiment, by acquiring the movement speed information and combining the wind speed information, it can be determined whether the user is safe currently, and a safety prompt message is sent to the user to remind the user of safety. Through combining motion speed information and wind speed information, the safety of the user is reminded, and the user is prevented from being injured, so that the use experience of the user is improved.

For example, the movement speed information may be detected by other devices interacting with the first earpiece using a sensor. The other devices may be wearable devices or mobile devices.

The exercise speed information may be, for example, a riding speed of the user during riding or a running speed of the user during running. Under different movement speed information, the safety limit is different, so that different safety prompt information needs to be sent to the user to avoid the influence on the use experience of the user due to false reminding.

By acquiring and comparing the wind speed information of the two earphones, the wind direction information can be determined according to the size of the wind speed information. According to the wind direction information, a wind direction prompt message is sent to the user, so that the user can adjust the current motion state, and the use experience of the user is improved.

According to the direction of wind speed, wind direction information is further determined, and therefore the function of wind direction determination can be achieved through the earphone, and the use experience of a user is improved. In an exemplary embodiment, the first relative position information of the second microphone and the third microphone is perpendicular to the wind direction information, and if the third energy parameter in the third microphone signal is greater than the first preset energy threshold, the wind direction information is oriented perpendicular to the first relative position information. If the first relative position information is north, the wind direction information is east. The first relative position information of the second microphone and the third microphone is perpendicular to the wind direction information, and if the third energy parameter in the third microphone signal is larger than the first preset energy threshold value, the wind direction information is perpendicular to the first relative position information. If the first relative position information is northward, the wind direction information is westward.

Illustratively, the wind direction information and the movement direction information in step S800 satisfy the preset condition, and may be that the preset condition is confirmed to be satisfied when the wind direction information is the same as the movement direction information. It may be that when the wind direction information is opposite to the movement direction information, it is confirmed that the preset condition is satisfied. Or when the wind direction information and the movement direction information form a certain angle, the preset condition is confirmed to be met.
