[0043] In daily life, in addition to satisfying people's needs for listening to music, the earphone 100 also has an important function of making calls. The calling function of the earphone 100 is slightly different from the music playing function. In addition to the sound of the earphone 100 speaker, the microphone of the earphone 100 plays a very critical role. It is particularly important for the microphone to clearly transmit the voice of the earphone 100 user 200 to the remote end in a complex and changing environment. The most common situation is when making calls in windy weather conditions. The interference of wind noise on the voice of the earphone 100 user 200 will affect the microphone's sound pickup and transmission, and thus affect the remote user experience.

[0044] Most current windproof designs are designed to provide structural protection, such as the microphone sound inlet is not at the tip, and the sound inlet is chamfered to prevent wind noise caused by eddy currents; in addition, windproof sponges are added to the microphone sound inlet or the microphone front cavity to absorb wind noise and reduce the impact on the microphone. All of the above can handle wind noise to a limited extent, but are easily restricted by product ID size, mold, etc., and the windproof effect of the above windproof design is greatly reduced due to its inflexibility and poor environmental adaptability. These conventional designs are not within the scope of this solution.

[0045] Figure 1 The method flow chart of the method for reducing wind noise of the earphone 100 according to the embodiment of the present invention is schematically shown. Figure 1 As shown, the present invention proposes a method for reducing wind noise of earphone 100, a noise reduction device, earphone 100 and a computer storage medium. The earphone 100 of the present invention is equipped with a gyroscope and a GPS positioning component, and the method for reducing wind noise of earphone 100 includes:

[0046] S1: Obtain wind force information of the location of the earphone 100 and direction information of the sound inlet of the microphone of the earphone 100;

[0047] S2: Calculate the actual wind noise energy based on the wind force information and the sound inlet direction information;

[0048] S3: According to the actual wind noise energy, the corresponding audio is matched and the wind noise at the sound inlet is reversely offset.

[0049] According to the technical solution of the present invention, when the user 200 wears the earphone 100 in an outdoor use environment at a certain time and place facing a certain direction, the product will automatically match the wind force information of the user 200's location and the direction information of the sound inlet of the microphone of the earphone 100. Through the wind force information and the direction information of the sound inlet of the microphone, the actual wind noise energy can be calculated, and the corresponding audio is matched to act reversely on the real-time wind noise at the sound inlet of the earphone 100, so as to offset the noise caused by the wind blowing in through the sound inlet of the microphone, thereby achieving the effect of intelligent noise reduction of the earphone 100 according to the wind force.

[0050] Specifically, in this embodiment, the earphone 100 can obtain the real-time position of the earphone 100 through the built-in GPS (Global Positioning System) and other positioning components, and obtain the weather information of this position through the real-time position, wherein the weather information includes wind direction, thereby achieving the purpose of obtaining the wind direction information of the location of the earphone 100.

[0051] Specifically, in this embodiment, the positioning component may also be a Beidou positioning and navigation module, which is mainly used to locate the real-time position of the product.

[0052] Specifically, in this embodiment, a gyroscope is provided in the earphone 100. The gyroscope is mainly based on the law of conservation of angular momentum and is a device capable of sensing and maintaining direction. The earphone 100 can obtain the orientation information of the sound inlet of the microphone of the earphone 100 according to the gyroscope. Among them, the arrangement of the gyroscope needs to be adapted and matched with the orientation of the sound inlet in advance, thereby improving the precision and accuracy.

[0053] Specifically, the gyroscope module is a gyroscope module provided in the earphone 100 itself, and is mainly used to identify the direction of the sound inlet of the microphone when the earphone 100 is normally worn (ie, the direction of the user 200).

[0054] In some embodiments of the present invention, Figure 2 As shown, obtaining wind force information at the location of the headset 100 includes:

[0055] The wind force information includes wind force level, wind direction and initial wind noise energy matching the wind force level.

[0056] Specifically, in this embodiment, the wind direction refers to the direction from which the wind blows. The direction of the sound inlet of the microphone is the axial direction of the sound inlet.

[0057] Specifically, in this embodiment, the orientation of the microphone sound inlet is mainly detected by the built-in gyroscope of the earphone 100 (the gyroscope is a device that can help determine the direction and position by detecting the change of the rotation of the object, and uses the principle of rotational inertia to measure the direction through the mechanical effect of rotation). When the user 200 wears the earphone 100 correctly, the gyroscope starts to work in real time, and the gyroscope will automatically calibrate the front direction to the direction of the microphone sound inlet. After the wearer turns around or turns his head, the defined front direction will change with the change of the orientation of the microphone sound inlet. When the positive direction is defined, the orientation of the microphone sound inlet is defined accordingly. Combined with the upwind direction, the above-mentioned orientation angle is naturally defined accordingly.

[0058] In some embodiments of the present invention, Figure 2 As shown in FIG. 1 , according to the wind force information and the sound inlet direction information, the actual wind noise energy is calculated including:

[0059] Determine the angle between the wind direction and the sound inlet direction according to the wind direction and the sound inlet direction information;

[0060] The actual wind noise energy is calculated based on the orientation angle and the initial wind noise energy.

[0061] In some embodiments of the present invention, Figure 2 and 3 As shown, according to the orientation angle and the initial wind noise energy, the actual wind noise energy is calculated including:

[0062] According to the obtuse angle, using formula Α 实际 =Α 初始 *sin(α-90°) calculates the actual wind noise energy;

[0063] Among them, Α 实际 is the actual wind noise energy, Α 初始 is the initial wind noise energy, and α is the orientation angle.

[0064] Specifically, in this embodiment, if Figure 2 and 3 As shown, when the wearer wears the headset 100 at a place where the angle with the wind direction is α, the wind noise energy corresponding to the wind force level at this time and place is Α, so the system immediately downloads and analyzes the corresponding energy level from the cloud storage module (i.e., the cloud service module or wind force database, which is mainly used to store audio recording files of noise levels corresponding to each level of wind force. The recording files are files recorded by simulating the wearer under laboratory conditions under different noise levels) to offset the wind noise. The absolute value of the energy level is Αsin (α-90°), and the direction is opposite to that of the wind noise. Among them, the signal direction of the wind noise energy and the actual wind noise energy output is opposite, so that the effect of mutual offset can be achieved.

[0065] Further, in this embodiment, if Figure 2 and 3 As shown, when the user 200 wears the earphone 100, the angle between the wind direction and the wind direction is divided into three cases. In the first case, the wind direction (i.e., the wind blowing direction) is opposite to the direction of the microphone sound inlet (i.e., the wind direction and the direction of the microphone sound inlet are opposite), that is, the wind direction and the direction of the microphone sound inlet are set at an obtuse angle, and the wind can blow towards the sound inlet. At this time, the angle between the wind direction and the direction of the microphone sound inlet is α, and the range of the angle is 0°<α<180°. Assuming that the wind noise energy corresponding to the wind force level at this time is Α, the absolute value of the component of the wind noise in the direction of the microphone sound inlet is Αsin(α-90°). Because the wind direction is a vector, the direction needs to be considered. Taking the direction of the microphone sound inlet as positive, the component of the wind noise in this direction is -Αsinα.

[0066] In some embodiments of the present invention, Figure 4 and 5 As shown in FIG. 1 , according to the wind force information and the sound inlet direction information, the actual wind noise energy is calculated including:

[0067] According to the orientation angle of 90° or 270°, it is determined that the actual wind noise energy is 0.

[0068] Specifically, in this embodiment, if Figure 4 and 5 As shown, there are three cases when the angle between the user 200 wearing the earphone 100 and the wind direction is. In the second case, the angle between the wind direction and the direction of the sound inlet of the microphone of the earphone 100 is 90° or 270°. At this time, the wind direction and the direction of the sound inlet are set perpendicularly, and the wind blows in the direction perpendicular to the direction of the sound inlet of the microphone, that is, the wind blows toward the side wall of the earphone 100 in a direction perpendicular to the direction of the sound inlet, which will not affect the sound inlet of the earphone 100. Therefore, in this case, it is considered that the wind does not directly act on the sound inlet of the microphone, and the noise generated by the wind on the microphone is very little, and thus there is no need to reverse the real-time wind noise at the sound inlet of the earphone 100 through actual wind noise energy.

[0069] In some embodiments of the present invention, calculating the actual wind noise energy according to the wind force information and the sound inlet hole orientation information includes:

[0070] Since the orientation angle is an acute angle, it is determined that the actual wind noise energy is 0.

[0071] Specifically, in this embodiment, the angle between the user 200 wearing the earphone 100 and the wind direction is divided into three cases. In the third case, the angle between the wind direction and the direction of the sound inlet of the earphone 100 microphone is an acute angle. At this time, the wind direction and the direction of the sound inlet are set in the same direction, and the wind blows in the opposite direction of the sound inlet of the microphone, that is, the wind blows towards the back wall of the earphone 100 along the direction of the sound inlet, which will not affect the sound inlet of the earphone 100. Therefore, in this case, it is considered that the wind does not directly act on the sound inlet of the microphone, and the noise generated by the wind on the microphone is very little, and thus there is no need to reverse the actual wind noise energy to the real-time wind noise at the sound inlet of the earphone 100.

[0072] Specifically, Figure 6 As shown, according to the orientation angle of 0°, the actual wind noise energy is determined to be 0. In this case, it is not necessary to use the actual wind noise energy to act inversely on the real-time wind noise at the sound inlet of the earphone 100.

[0073] In some embodiments of the present invention, Figure 2 As shown, the initial wind noise energy is obtained by analyzing the audio files of wind noise of different wind force levels. In this embodiment, a plurality of audio files are stored in the cloud storage module, each audio file corresponds to the wind noise energy of a wind force level, that is, each wind force level can analyze the corresponding initial noise energy from a corresponding audio file in the cloud storage module.

[0074] In some embodiments of the present invention, the initial wind noise energy is determined by the frequency of the audio file and the RMS (Root Mean Square) value of the corresponding response value of the audio file. Specifically, in this embodiment, the cloud storage module can store audio files corresponding to the wind noise energy corresponding to each level of wind at each location. The wind noise energy is obtained by analyzing the files recorded by wind noise of different levels, mainly determined by the RMS value (Root Mean Square) of the frequency and the corresponding response value, that is, the RMS of the frequency response curve is obtained. Therefore, the initial wind noise energy can be obtained from the cloud storage module according to the wind force level.

[0075] In some embodiments of the present invention, multiple audio files that match the actual wind noise energy are stored in the cloud storage module. In this embodiment, after the actual wind noise energy is calculated, a corresponding audio file can be matched from the cloud storage module, and then the earphone 100 reversely cancels the wind noise of the sound inlet according to the audio recording file that matches the actual wind noise energy.

[0076] The present invention also provides a noise reduction device for earphones 100, the noise reduction device comprising:

[0077] An acquisition unit, used to acquire wind force information of the location of the earphone 100 and direction information of the sound inlet hole of the microphone of the earphone 100;

[0078] A calculation unit, used to calculate actual wind noise energy according to wind force information and sound inlet hole direction information;

[0079] The output unit is used to match the corresponding audio and reversely offset the wind noise at the sound inlet.

[0080] According to the technical solution of the present invention, when the user 200 wears the earphone 100 in an outdoor use environment at a certain time and place facing a certain direction, the acquisition unit can obtain the wind force information of the user 200 and the direction information of the sound inlet of the microphone of the earphone 100. Through the wind force information and the direction information of the sound inlet of the microphone, the actual wind noise energy can be calculated by the calculation unit, and the corresponding audio is matched to act reversely on the real-time wind noise at the sound inlet of the earphone 100 through the output unit, so as to offset the noise caused by the wind blowing in through the sound inlet of the microphone, thereby achieving the effect of intelligent noise reduction of the earphone 100 according to the wind force.

[0081] The present invention further provides an earphone 100, comprising:

[0082] A memory configured to store executable code;

[0083] The processor is configured to read the executable code and run a program corresponding to the executable code to implement the method for reducing wind noise of the earphone 100 according to the above.

During the noise reduction process, the product will automatically match the wind force information of the user 200 and the direction information of the sound inlet of the microphone of the earphone 100. Through the wind force information and the direction information of the sound inlet of the microphone, the actual wind noise energy can be calculated, and the corresponding audio is matched to act reversely on the real-time wind noise at the sound inlet of the earphone 100 to offset the noise caused by the wind blowing in through the sound inlet of the microphone, thereby achieving the effect of intelligent noise reduction of the earphone 100 according to the wind force.
