Description
Technical Field

Background
The pass-through mode is a common technique for headphones, and is intended to enable a wearer to hear ambient sounds without taking off the headphones. The common practice is to pick up external environmental sound through a microphone outside the earphone, gain-process the picked-up microphone signal (to obtain transparent sound), and send the sound to the human ear through an earphone speaker. At present, when a user covers the earphone by hand, the transparent sound played by the loudspeaker is picked up by the microphone again due to the leakage of the earphone, the transparent sound forms a closed loop in the link, and howling can be generated when the transparent sound is processed by the gain. The existing solution to howling is to reduce the gain value when it is detected that the external environment signal picked up by the microphone exceeds a certain threshold. However, this solution has a problem that when external loud sounds such as door closing sounds suddenly appear, the microphone monitoring function is triggered by mistake, so that the gain value is reduced, and the user can obviously feel that the external sounds become stuffy with the door closing sounds, and the user experience is poor.

Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a first embodiment of a method for controlling a headset through mode according to the present invention.
The embodiments of the present invention provide embodiments of a method for controlling a headset pass-through mode, and it should be noted that although a logic sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown or described herein. The earphone penetrating mode control method is applied to earphone equipment, the earphone equipment can comprise one earphone or two earphones, and as the earphone penetrating mode control methods of the two earphones are the same, the earphone equipment comprises one earphone by default for example for embodiment explanation for convenience of description. In this embodiment, the method for controlling the earphone through mode includes:
Step S10, when the earphone equipment is in the transparent mode, acquiring a first signal which is played through the loudspeaker and picked up by the microphone, wherein the frequency of the first signal is out of the hearing frequency range of a user;
the earphone device may include a speaker and a microphone disposed at a side of the earphone device near the external environment for picking up external environment signals. The earphone device is provided with the transparent mode, when the earphone device is in the transparent mode, the earphone device can pick up external environment signals through the microphone, gain processing is carried out on the external environment signals, and then the external environment signals are played through the loudspeaker, so that when a user wears the earphone, the external sound heard is not influenced because the earphone blocks the auditory canal. Gain processing generally employs a pass filter for gain processing, and the specific manner is not limited herein.
In order to solve the problem of howling caused by ear covering in the pass-through mode and avoid bad experience effect of users on the pass-through mode caused by false touch when loud sounds are generated due to the fact that the howling problem is overcome, in this embodiment, a section of sound signal with specific frequency (hereinafter referred to as a first signal) is played by a loudspeaker when the earphone device is in the pass-through mode, the first signal is picked up by a microphone, whether the users cover the ears or not is accurately determined by judging the energy of the picked-up first signal, and then gain values are accurately adjusted, so that the howling is avoided, and gain adjustment when the users cover the ears due to false touch of loud sounds is avoided. Wherein the specific first signal is a signal having a frequency outside the range of the hearing of the user, i.e. which is not audible to the speaker by the user of the earphone device. The hearing frequency ranges of each person may be different, so in a specific embodiment, the frequency of the first signal may be selected empirically to accommodate most users, or may be set for a particular user, e.g. by playing different frequency sound signals through a speaker to test the hearing frequency range of a particular user, and the frequency of the first signal is selected according to the measured hearing frequency range.
When the earphone device is in the pass-through mode, the timing of playing the first signal through the speaker is not limited in the embodiment. For example, in an embodiment, the earphone device may play the first signal through the speaker uninterruptedly or periodically while in the pass-through mode, and accordingly, pick up the first signal through the microphone uninterruptedly or periodically; when the first signals are played by the loudspeaker at regular time, the first signals can be played once at intervals, each time a certain time is played, and the time interval between two adjacent first signals can be set to be short, so that howling caused by ear covering of a user in a period of non-playing in the middle is avoided. In another embodiment, the earphone device may play the first signal through the speaker when detecting that the energy value of the external environment signal picked up by the microphone is greater than a threshold value while in the pass-through mode; wherein the gain value may be maintained at a normal level in the pass-through mode when the energy value of the ambient signal is less than the threshold.
It should be noted that, when the speaker does not play the first signal, the sound signal picked up by the microphone only includes the external environment signal; when the loudspeaker plays the first signal, the sound signal picked up by the microphone comprises the first signal and an external environment signal. When the speaker plays the first signal, the headphone device can extract the first signal from the sound signal picked up by the microphone, since the first signal is known.
Further, in an embodiment, the step of acquiring the first signal played through the speaker and picked up by the microphone in the step S10 includes:
step S101, acquiring sound signals picked up by the microphone;
step S102, filtering the sound signal to obtain a first signal that is played through the speaker and picked up by the microphone.
The earphone device can play the first signal through the loudspeaker, acquire the sound signal picked up by the microphone, and filter the sound signal to acquire the first signal picked up by the microphone. The filtering may specifically be to set a filter according to the frequency of the first signal, and obtain the first signal by filtering with the filter. For example, when the frequency of the first signal is high, a high-pass filter may be set for filtering, and when the frequency of the first signal is low, a low-pass filter may be set for filtering, or a band-pass filter may be set for filtering, which is not limited in this embodiment.
Step S20, if the signal energy of the picked-up first signal is less than or equal to a first energy threshold, controlling the earphone device to perform gain processing by adopting a gain value greater than or equal to a first gain threshold in the pass-through mode;
After the first signal is picked up by the microphone, it may be determined whether the signal energy of the picked-up first signal is greater than a first energy threshold. The first energy threshold may be set through a test, so that when the signal energy of the picked-up first signal is greater than the first energy threshold, the user is indicated to cover the ear by hand, and when the signal energy of the picked-up first signal is less than or equal to the first energy threshold, the user is indicated to not cover the ear. When the user wears the earphone to cover the ear by hand and wear leakage occurs, the signal energy of the first signal picked up by the microphone is larger than the signal energy of the first signal picked up by the microphone when the user does not cover the ear, so that whether the user covers the ear can be judged by comparing the signal energy of the first signal with the set first energy threshold.
If the signal energy of the picked-up first signal is smaller than or equal to the first energy threshold, the user is not covered by the ear, and at this time, the earphone device can be controlled to perform gain processing by adopting a gain value larger than or equal to the first gain threshold in the pass-through mode. The first gain threshold value can be set according to experience, the first gain threshold value can achieve the transparent effect of external sound when the user does not cover the ear, howling cannot occur, and howling may occur when the user covers the ear by performing gain processing with the first gain threshold value. When the external environment generates sudden loud sound but the user does not cover the ears, the user can be determined that the user does not cover the ears by judging the signal energy of the picked-up first signal, and then gain processing is still performed with a normal gain value, so that the user can hear more real external sound, namely the permeation effect is more real.
Specific implementation details of controlling the earphone device to perform gain processing with a gain value greater than or equal to the first gain threshold in the pass-through mode are not limited in this embodiment. For example, in an embodiment, the earphone device may first determine whether the currently employed gain value is greater than or equal to the first gain threshold when detecting that the signal energy of the picked-up first signal is less than or equal to the first energy threshold; if the gain value is greater than or equal to the first gain threshold value, the earphone equipment can be kept at the current gain value without adjustment; if the gain value is smaller than the first gain threshold value, the earphone device may directly set the gain value to a value greater than or equal to the first gain threshold value, or may increase the gain value based on the current gain value according to a certain step, and at least one step of adjustment is performed to make the gain value reach a level greater than or equal to the first gain threshold value. As another example, in another embodiment, the headphone device may directly set the gain value to a value greater than or equal to the first gain threshold when detecting that the signal energy of the picked-up first signal is less than or equal to the first energy threshold.
Step S30, if the signal energy of the picked-up first signal is greater than the first energy threshold, controlling the earphone device to perform gain processing by adopting a gain value smaller than a second gain threshold in the pass-through mode, where the second gain threshold is smaller than or equal to the first gain threshold.
If the signal energy of the picked-up first signal is greater than the first energy threshold, it indicates that the user covers the ear, and at this time, in order to avoid howling, the earphone device may be controlled to perform gain processing in the pass-through mode by adopting a gain value smaller than the second gain threshold. The second gain threshold may be set empirically, where the second gain threshold is a gain value that is not howling caused by leakage when the user covers the ear, and may be set smaller than or equal to the first gain threshold according to specific situations.
Further, in an embodiment, when detecting that the signal energy of the picked up first signal is greater than the first energy threshold, the earphone device may first detect whether the energy value of the external environment signal picked up by the microphone is greater than the second energy threshold, if so, control the earphone device to perform gain processing in the pass-through mode by using a gain value smaller than the second gain threshold, and if so, control the earphone device to perform gain processing in the pass-through mode by using a gain value greater than or equal to the first gain threshold. The second energy threshold may be set as needed, so that when the energy value of the external environment signal picked up by the microphone is smaller than or equal to the second energy threshold, howling does not occur, and when the energy value of the external environment signal picked up by the microphone is greater than the second energy threshold, howling may occur for a period of time. That is, if the user covers the ear, but the signal energy of the external environment signal does not reach the level where howling occurs, the normal gain level may still be maintained, and when the signal energy of the external environment signal reaches the level where howling occurs, the gain value is adjusted to be smaller, so as to avoid the occurrence of howling.
Specific implementation details of controlling the earphone device to perform gain processing with a gain value greater than or equal to the first gain threshold in the pass-through mode are not limited in this embodiment. For example, in an embodiment, the earphone device may directly set the gain value to a value smaller than the second gain threshold value when it is detected that the signal energy of the picked-up first signal is larger than the first energy threshold value.
Further, in another embodiment, the step S30 includes:
step S301, if the signal energy of the picked up first signal is greater than the first energy threshold, detecting whether the gain value adopted by the earphone device in the pass-through mode is smaller than a second gain threshold;
step S302, if the gain value adopted by the earphone device in the pass-through mode is smaller than the second gain threshold value, the gain value adopted by the earphone device in the pass-through mode is kept unchanged;
step S303, if the gain value currently adopted by the earphone device in the pass-through mode is greater than or equal to the second gain threshold, reducing the gain value currently adopted by the earphone device in the pass-through mode to be less than the second gain threshold according to a preset step.
The earphone device may first determine whether the currently employed gain value is smaller than the second gain threshold value when detecting that the signal energy of the picked-up first signal is larger than the first energy threshold value. If the currently adopted gain value is smaller than the second gain threshold value, the earphone equipment can be kept at the current gain value without adjustment; if the currently adopted gain value is greater than or equal to the second gain threshold, the earphone device may directly set the gain value to a value smaller than the second gain threshold, or may reduce the gain value based on the current gain value according to a preset step, and adjust the gain value by at least one step to reach a level smaller than the second gain threshold. The preset step may be set as required, which is not limited in this embodiment.
In this embodiment, when the earphone device is in the pass-through mode, a first signal played through a speaker of the earphone device and picked up by a microphone is acquired, a frequency of the first signal is set to be out of a hearing frequency range of a user, when a signal energy of the first signal is less than or equal to a first energy threshold value, the earphone device is controlled to perform gain processing with a gain value greater than or equal to a first gain threshold value in the pass-through mode, and when the signal energy of the first signal is greater than the first energy threshold value, the earphone device is controlled to perform gain processing with a gain value less than a second gain threshold value in the pass-through mode, and the second gain threshold value is set to be less than or equal to the first gain threshold value. Through adopting the speaker to broadcast the signal that the user can't hear under penetrating mode to judge through the energy size to this signal that the microphone picked up in order to confirm whether the user covers the ear, and then adjust the gain value little when the user covers the ear, adopt normal gain value to carry out gain processing when the user does not cover the ear, can enough avoid the howling that causes because of covering the ear, can avoid the external sudden loud sound to cause gain value misadjustment again and lead to penetrating effect not good, improved the user experience to earphone penetrating mode.
Further, based on the first embodiment, a second embodiment of the method for controlling a headset through mode of the present invention is provided, in this embodiment, before the step of acquiring the first signal played by the speaker and picked up by the microphone in step S10, the method further includes:
step S40, when the earphone equipment is in the through mode and the gain value adopted by the earphone equipment is larger than or equal to the first gain threshold value, acquiring a first external environment signal picked up by the microphone currently;
in this embodiment, in order to avoid excessive consumption of resources of the earphone device caused by the earphone device always sending the first signal, the first signal may be played through the speaker when the signal energy of the external environment signal picked up by the microphone of the earphone device is greater than the second energy threshold.
Specifically, when the earphone device enters the pass-through mode, the gain value adopted by default may be greater than or equal to the first gain threshold, so as to ensure the normal pass-through function of the pass-through mode. And then, when the earphone equipment is in the through mode and the adopted gain value is larger than or equal to a first gain threshold value, acquiring an external environment signal (hereinafter referred to as a first external environment signal for convenience in distinguishing) picked up by the current microphone. It should be noted that, when the earphone device is in the pass-through mode and the adopted gain value is greater than or equal to the first gain threshold, the earphone device will acquire the external environment signal picked up by the microphone, so as to monitor whether the external environment has loud sound in real time.
And step S50, if the signal energy of the first external environment signal is larger than a second energy threshold value, playing the first signal through the loudspeaker.
After the first external environment signal is picked up, it may be determined whether the signal energy of the first external environment signal is greater than a second energy threshold. If the signal energy of the first external environment signal is greater than the second energy threshold, it is indicated that if the user continuously covers the ear, howling may be caused, at this time, the earphone device may play the first signal through the speaker, pick up the first signal through the microphone, and determine whether the user covers the ear at this time by determining the signal energy of the picked first signal; if the user ear covering is determined, the explanation is that the user ear covering causes larger signal energy of the external environment signal, and the gain value is reduced to be lower than a second gain threshold value at the moment so as to avoid howling; if the user is determined to not cover the ears, the outside natural loud sound is indicated, and at the moment, the gain value is kept at the first gain threshold value or above, so that the normal penetrating function is ensured.
When the earphone device is in the pass-through mode and the gain value adopted is smaller than the second gain threshold, the earphone device may restore the gain value to a level greater than or equal to the second gain threshold when a certain condition is satisfied, where the condition may be that the gain value is restored when the user is detected to be not covered by the ear by a certain method, or that the signal energy of the external environment signal is detected to be lower than the second energy threshold, which is not a limitation in the present embodiment.
Further, in an embodiment, after the step S30, the method further includes:
step A10, when the earphone device is in the pass-through mode and the gain value adopted by the earphone device is smaller than the second gain threshold value, playing a second signal through the loudspeaker, and picking up the second signal through the microphone, wherein the frequency of the second signal is outside the hearing frequency range of the user;
when the gain value adopted by the earphone device is smaller than the second gain threshold value, the earphone device can play the second signal through the loudspeaker. The second signal may be different from the first signal or the same signal, but the frequencies of the second signal and the first signal are both out of the hearing frequency range of the user, that is, by judging the energy of the second signal picked up by the microphone, it is also able to determine whether the user is ear-covered.
It should be noted that, when the earphone device is in the pass-through mode and the adopted gain value is smaller than the second gain threshold, the earphone device plays the second signal through the speaker to determine whether the user covers the ear in real time.
Step A20, if the signal energy of the picked-up second signal is smaller than or equal to the first energy threshold, controlling the earphone device to perform gain processing by adopting a gain value larger than or equal to the first gain threshold in the pass-through mode;
After the second signal is picked up by the microphone, it may be determined whether the signal energy of the second signal is less than or equal to the first energy threshold. Similarly to the first signal, when the signal energy of the second signal is less than or equal to the first energy threshold, it is indicated that the user does not cover the ear, and at this time, the earphone device may be controlled to perform gain processing with a gain value greater than or equal to the first gain threshold in the pass-through mode, that is, to restore the gain value to a normal level, so as to ensure a normal pass-through function. At this time, since the previous gain value is smaller than the second gain threshold value, when the earphone device is controlled to perform gain processing with a gain value greater than or equal to the first gain threshold value, the gain value may specifically be set directly to a value greater than or equal to the first gain threshold value, or may be increased in a certain step on the basis of the current gain value, and the gain value is adjusted at least once to reach a level greater than or equal to the first gain threshold value.
And step A30, if the signal energy of the picked-up second signal is larger than the first energy threshold value, controlling the earphone equipment to perform gain processing by adopting a gain value smaller than the second gain threshold value in the pass-through mode.
When the signal energy of the second signal is greater than the first energy threshold, the user is still in the ear covering state, and at the moment, the earphone equipment is still controlled to perform gain processing by adopting a gain value smaller than the second gain threshold so as to avoid howling. Since the previous gain value is smaller than the second gain threshold value, when the earphone device is controlled to perform gain processing with the gain value smaller than the second gain threshold value, the gain value may be specifically set to be a value smaller than the second gain threshold value directly, or the current gain value may be kept unchanged.
If the gain value is reduced when the signal energy of the external environment signal picked up by the microphone is detected to be greater than a certain threshold value, and the gain value is recovered when the signal energy is smaller than or equal to the threshold value, then the noise of the earphone is disappeared after appearing when the user covers the ear, and the noise is continuously circulated when the user is continuously covered, so that the user experience is poor. In this embodiment, the earphone device adjusts the gain value down when detecting the ear covering, and the gain value is not recovered until the ear covering is not detected, so that the situation that the whistle suddenly disappears is avoided.
Further, in an embodiment, after the step S30, the method further includes:
step B10, when the earphone device is in the pass-through mode and the gain value adopted by the earphone device is smaller than the second gain threshold value, acquiring a second external environment signal picked up by the microphone currently;
when the earphone device is in the pass-through mode and the gain value adopted when performing gain processing is smaller than the second gain threshold value, the earphone device acquires an external environment signal (hereinafter referred to as a second external environment signal for convenience of distinction) picked up by the current microphone. It should be noted that, when the earphone device is in the pass-through mode and the adopted gain value is smaller than the second gain threshold, the earphone device will acquire the external environment signal picked up by the microphone, so as to monitor in real time whether the external environment has loud sound.
Step B20, if the signal energy of the second external environment signal is smaller than or equal to the second energy threshold, controlling the earphone device to perform gain processing by adopting a gain value larger than or equal to the first gain threshold in the pass-through mode;
after the second external environment signal is picked up, it may be determined whether the signal energy of the second external environment signal is greater than a second energy threshold. If the signal energy of the second external environment signal is smaller than or equal to the second energy threshold value, the howling cannot occur at the moment; at this time, the earphone device may be controlled to perform gain processing by using a gain value greater than or equal to the first gain threshold in the pass-through mode, so as to ensure a normal pass-through function.
Since the previous gain value is smaller than the second gain threshold, when the earphone device is controlled to perform gain processing by adopting the gain value larger than or equal to the first gain threshold, the gain value may be specifically set to a value larger than or equal to the first gain threshold directly, or the gain value may be increased according to a certain step on the basis of the current gain value, and the gain value is adjusted at least once to reach a level larger than or equal to the first gain threshold.
And step B30, if the signal energy of the second external environment signal is greater than the second energy threshold, controlling the earphone equipment to perform gain processing by adopting a gain value smaller than the second gain threshold in the pass-through mode.
If the signal energy of the second external environment signal is greater than the second energy threshold, it is indicated that if the user continuously covers the ear, howling may be caused, and at this time, the earphone device is still controlled to perform gain processing by adopting a gain value smaller than the second gain threshold, so as to avoid howling. Since the previous gain value is smaller than the second gain threshold value, when the earphone device is controlled to perform gain processing with the gain value smaller than the second gain threshold value, the gain value may be specifically set to be a value smaller than the second gain threshold value directly, or the current gain value may be kept unchanged.
Further, in an embodiment, after the step S40, the method further includes:
step S60, if the signal energy of the first external environment signal is less than or equal to the second energy threshold, controlling the earphone device to perform gain processing in the pass-through mode by using a gain value greater than or equal to the first gain threshold.
If the signal energy of the first external environment signal is smaller than or equal to the second energy threshold value, the howling cannot occur at the moment; at this time, the earphone device may be controlled to perform gain processing by using a gain value greater than or equal to the first gain threshold in the pass-through mode, so as to ensure a normal pass-through function.
