Technical Field

Background

With the continuous development of modern science and technology, the diversification and the intelligence of electronic products are greatly improved, and particularly, the proximity detection technology is gradually mature and is gradually applied to various electronic devices, such as wireless earphones.

In the prior art, mutual capacitance detection technology is applied to earphones to determine whether the earphones are worn on the ears of a person. Mutual capacitance detection uses two sensors, one for sending detection signals and one for receiving signals. The amplitude of the received signal will vary as the magnitude of the mutual capacitance varies. When the human body is close to, the human body can influence the electric field between two mutual capacitance sensors, reduces the mutual capacitance value, can judge whether the earphone is worn in the ear through the variable quantity that detects the mutual capacitance value. When the earphone enters a wearing state, the functions of Bluetooth connection, music playing, noise reduction and the like are started; otherwise, if the wearing state is not entered, the functions are closed, thereby achieving the purpose of reducing power consumption. However, in order to facilitate charging of the earphone, it is common to expose the ground of the internal circuit of the earphone, and when a person takes the earphone, the hand may contact the ground of the internal circuit exposed from the earphone, so that the ground of the internal circuit is communicated with the person. When a person takes the earphone and touches the ground of the internal circuit of the earphone, the reading of the mutual capacitance detection circuit can be greatly changed, so that the detection value characteristics of the mutual capacitance detection circuit are similar to those of the earphone worn by the person, misjudgment is easily caused, and the state of the earphone is judged to be a wearing state.

An execution main body of the earphone state detection method in the embodiment of the present application may be a server, a terminal, or other devices with logic processing capability, which is not limited in the embodiment of the present application. For convenience of description, the following description will be given taking the execution body as an example.

Referring to fig. 3, fig. 3 is a schematic flowchart illustrating an embodiment of a method for detecting a state of an earphone according to an embodiment of the present application, where the method is applied to the earphone shown in fig. 1, and an embodiment of the method for detecting a state of an earphone according to the embodiment of the present application includes:

301. the terminal acquires a first mutual capacitance variable quantity through a data processing unit;

the mutual capacitance is the capacitance between one sensing block and another sensing block, when an excitation signal is applied to one sensing block, the excitation signal can be sensed and received on the other sensing block due to the existence of the mutual capacitance, and the magnitude and the phase shift of the received signal are related to the frequency of the excitation signal and the magnitude of the mutual capacitance. Two sensors are needed for mutual capacitance detection, one for sending detection signals and one for receiving signals. The amplitude of the received signal will vary as the magnitude of the mutual capacitance varies. When a human body approaches, the human body can influence an electric field between the two mutual capacitance sensors, and the mutual capacitance value is reduced.

When a user approaches the earphone, no matter the user wears the earphone on the ear or the user touches the ground of the exposed internal circuit of the earphone with a hand, the change of the mutual capacitance value between the first sensor and the second sensor is caused, at the moment, the terminal can acquire the first mutual capacitance change amount through the data processing unit of the earphone, and the first mutual capacitance change amount is the change amount of the mutual capacitance value between the first sensor and the second sensor.

302. The terminal judges whether to trigger a proximity event of the earphone according to the first mutual capacitance variation, if so, the step 303 is executed;

after the terminal acquires the first mutual capacitance variation through the data processing unit of the earphone, it may be determined whether to trigger a proximity event of the earphone according to the first mutual capacitance variation, where the proximity event is an event that a person approaches the earphone, and if the terminal determines that the proximity event occurs, step 303 may be executed. If the approach event of the earphone is not triggered, on the premise that the equipment works normally, the condition that the earphone is touched to the ground of an internal circuit by a user does not exist naturally, so when the terminal determines that the approach event is not triggered, the step of acquiring the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit is not necessarily executed, and only when the approach event is determined to be triggered, the step of acquiring the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit is executed.

303. The terminal acquires a first self-capacitance variation and/or a second self-capacitance variation through the data processing unit;

when a proximity event triggering the headset is determined, this time including a number of situations, such as when the user is correctly wearing the headset to his ear, when the user's hand touches the ground of the internal circuit exposed by the headset, and so on. The terminal needs to acquire more information to determine the specific state of the headset after determining the proximity event triggering the headset, and therefore the terminal acquires the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit. The first self-capacitance variation is a variation of the self-capacitance of the first sensor, and the second self-capacitance variation is a variation of the self-capacitance of the second sensor.

304. And the terminal determines the wearing state of the earphone according to the first self-capacitance variation and/or the second self-capacitance variation.

After the terminal acquires the first self-capacitance variation and/or the second self-capacitance variation, because the condition that the user touches the ground of the internal circuit of the earphone but does not wear the earphone is compared with the condition that the user correctly wears the earphone to the ear, the caused first self-capacitance variation and/or second self-capacitance variation has obvious difference, so the terminal can determine the wearing state of the earphone according to the first self-capacitance variation and/or second self-capacitance variation. Wherein, the wearing state of the earphone comprises an unworn state and a worn state.

In this implementation, the terminal first obtains a first mutual capacitance variation through the data processing unit, where the first mutual capacitance variation is a variation of a mutual capacitance value between the first sensor and the second sensor, and then determines whether to trigger a proximity event of the earphone according to the first mutual capacitance variation, and when determining to trigger the proximity event of the earphone, obtains a first self-capacitance variation and/or a second self-capacitance variation through the data processing unit, where the first self-capacitance variation is a variation of a self-capacitance value of the first sensor, and the second self-capacitance variation is a variation of a self-capacitance value of the first sensor, and finally determines a wearing state of the earphone according to the first self-capacitance variation and/or the second self-capacitance variation. Whether the proximity event of the earphone is triggered or not is judged through the first mutual capacitance variation, if the proximity event of the earphone is triggered, the wearing state of the earphone is determined through the first self-capacitance variation and/or the second self-capacitance variation, the condition that the user does not wear the earphone when the user's hand contacts the ground of an internal circuit of the earphone is compared with the condition that the user correctly wears the earphone to the ear, and the caused first self-capacitance variation and/or second self-capacitance variation have obvious difference, so that the condition that the earphone is misjudged to be the wearing state can be reduced.

Referring to fig. 4, fig. 4 is a schematic flowchart of another embodiment of a method for detecting a state of an earphone according to an embodiment of the present application, applied to the earphone shown in fig. 1, where the another embodiment of the method for detecting a state of an earphone according to the embodiment of the present application includes:

401. the terminal acquires a first mutual capacitance value;

the mutual capacitance is the capacitance between one sensing block and another sensing block, when an excitation signal is applied to one sensing block, the excitation signal can be sensed and received on the other sensing block due to the existence of the mutual capacitance, and the magnitude and the phase shift of the received signal are related to the frequency of the excitation signal and the magnitude of the mutual capacitance. Two sensors are needed for mutual capacitance detection, one for sending detection signals and one for receiving signals. The amplitude of the received signal will vary as the magnitude of the mutual capacitance varies. When a human body approaches, the human body can influence an electric field between the two mutual capacitance sensors, and the mutual capacitance value is reduced.

When a user approaches the earphone, no matter the user wears the earphone on the ear or the user touches the ground of the exposed internal circuit of the earphone with a hand, the change of the mutual capacitance value between the first sensor and the second sensor is caused, and at the moment, the terminal can acquire the change of the mutual capacitance value between the first sensor and the second sensor through the data processing unit of the earphone.

And the terminal will acquire the variable quantity of the mutual capacitance value between the first sensor and the second sensor, and then need acquire the basic mutual capacitance value between the first sensor and the second sensor earlier to just can acquire the variable quantity of the mutual capacitance value according to the basic mutual capacitance value. Therefore, the terminal first obtains a first mutual capacitance value, which is a basic mutual capacitance value between the first sensor and the second sensor. It should be noted that the manner of acquiring the first mutual capacitance value by the terminal may include multiple manners, including directly acquiring a preset mutual capacitance value burned on the earphone as the first mutual capacitance value; when the proximity event of the headset is not triggered, acquiring, by a data processing unit of the headset, a mutual capacitance value between the first sensor and the second sensor as a first mutual capacitance value, which is not limited herein.

In the embodiment, the preset mutual capacitance value burnt on the earphone is directly obtained to be used as the first mutual capacitance value, so that the method is convenient and quick and has high efficiency; when the approach event of the earphone is not triggered, the accuracy of the mutual capacitance value between the first sensor and the second sensor is high by acquiring the mutual capacitance value as the first mutual capacitance value through the data processing unit of the earphone.

402. The terminal acquires a second mutual capacitance value between the first sensor and the second sensor in real time through the data processing unit;

in order to obtain the variation of the mutual capacitance value between the first sensor and the second sensor, the terminal needs to obtain the mutual capacitance value between the first sensor and the second sensor in real time as the second mutual capacitance value in addition to the first mutual capacitance value, and only after the first mutual capacitance value and the second mutual capacitance value are obtained, the terminal can further obtain the first mutual capacitance variation. Therefore, the terminal needs to obtain the second mutual capacitance value through the data processing unit in real time at this time.

403. The terminal calculates a first mutual capacitance variation according to the second mutual capacitance value and the first mutual capacitance value;

after the terminal acquires the first mutual capacitance value and the second mutual capacitance value at the same time, the first mutual capacitance variation can be calculated according to the second mutual capacitance value and the first mutual capacitance value. The specific calculation method may be to subtract the first mutual capacitance value from the second mutual capacitance value to obtain a difference, where the difference is the first mutual capacitance value variation.

404. The terminal judges whether the first mutual capacitance variation is larger than or equal to a third threshold, if so, step 405 is executed;

after obtaining the first mutual capacitance variation, the terminal may compare the first mutual capacitance variation with a third threshold, and if the first mutual capacitance variation is greater than or equal to the third threshold, step 405 may be executed. When the user is close to the earphone, for example, the hand of the user is close to the earphone, for example, only a few centimeters away from the earphone, or the user holds the earphone and touches the ground of the internal circuit of the earphone, the variation of the mutual capacitance value generated in the case that the user holds the earphone and touches the ground of the internal circuit of the earphone, or the variation of the mutual capacitance value generated in the case that the user holds the earphone and touches the ground of the internal circuit of the earphone and the user holds the earphone and wears the earphone on the ear, respectively, is very small, but the variation of the mutual capacitance value generated in other cases, for example, the case that the hand of the user is close to the earphone, for example, only a few centimeters away from the earphone, and the two cases, respectively, is obviously different. Therefore, a value can be preset as a third threshold value to distinguish between the case where the user correctly wears the earphone on the ear and the case where the user holds the earphone and touches the ground of the internal circuit of the earphone, which are different from the other cases in the amount of change in the mutual capacitance value.

In this embodiment, a preset value is used as the third threshold, so that the difference between the variation of the mutual capacitance value caused by the fact that the user correctly wears the earphone on the ear and the fact that the user grips the earphone and touches the ground of the internal circuit of the earphone with the hand can be effectively distinguished, and the possibility of misjudging that the wearing state of the earphone is the worn state is greatly reduced.

405. The terminal determines a proximity event triggering the earphone;

after determining that the first mutual capacitance variation is greater than or equal to the third threshold, the terminal may determine that a proximity event of the headset is triggered.

406. The terminal acquires a first self-capacitance value and/or a second self-capacitance value;

when a proximity event triggering the headset is determined, this time including a number of situations, such as when the user is correctly wearing the headset to his ear, when the user's hand touches the ground of the internal circuit exposed by the headset, and so on. Therefore, after determining that the proximity event of the headset is triggered, the terminal needs to acquire more information to determine the specific state of the headset, and therefore, the terminal acquires the change amount of the self-capacitance value of the first sensor and/or the change amount of the self-capacitance value of the second sensor through the data processing unit.

And the terminal needs to acquire the variation of the self-capacitance value of the first sensor, and then the basic self-capacitance value of the first sensor needs to be acquired first, so that the variation of the self-capacitance value can be acquired according to the basic self-capacitance value. Therefore, the terminal needs to first obtain a first self-capacitance value, which is the basic self-capacitance value of the first sensor. It should be noted that all the cases where the terminal acquires the first self-capacitance value may include multiple cases, including directly acquiring a self-capacitance value of a preset first sensor burned on the earphone as the first self-capacitance value; the method also includes acquiring, by a data processing unit of the headset, a self-capacitance value of the first sensor as a first self-capacitance value when the headset is not physically close to the headset, which is not limited herein.

Similarly, the terminal needs to acquire the variation of the self-capacitance value of the second sensor, and then needs to acquire the basic self-capacitance value of the second sensor first, so that the variation of the self-capacitance value can be acquired according to the basic self-capacitance value. Therefore, the terminal needs to first obtain a second self-capacitance value, which is the basic self-capacitance value of the second sensor. It should be noted that the terminal may obtain a plurality of second self-capacitance values, including directly obtaining a self-capacitance value of a preset second sensor burned on the earphone as the second self-capacitance value; the method also includes acquiring, by the data processing unit of the headset, the self-capacitance value of the second sensor as a second self-capacitance value when the headset is not physically close to the headset, which is not limited herein.

In this embodiment, directly acquire the self-capacitance value of burning record preset first sensor on the earphone as first self-capacitance value, convenient quick, efficient is favorable to reducing the time of judging the wearing mode of earphone for wearing the state to be favorable to improving with user experience. When no physics is close to the earphone, the data processing unit of earphone obtains the self-capacitance value of first sensor as first self-capacitance value, and the accuracy is high, can adapt to multiple external environment.

In this embodiment, directly acquire the self-capacitance value of burning record preset second sensor on the earphone as the second from the capacitance value, convenient quick, efficient is favorable to reducing the time of judging the wearing mode of earphone for wearing the state to be favorable to improving with user experience. When no physics is close to the earphone, the data processing unit of earphone obtains the self-capacitance value of second sensor as second self-capacitance value, and the accuracy is high, can adapt to multiple external environment.

407. The terminal acquires a third self-capacitance value of the first sensor and/or a fourth self-capacitance value of the second sensor in real time through the data processing unit;

in order to obtain the variation of the self-capacitance value of the first sensor, the terminal needs to obtain the self-capacitance value of the first sensor in real time as a third self-capacitance value in addition to the first self-capacitance value, and the terminal can further obtain the first self-capacitance variation only after the first self-capacitance value and the third self-capacitance value are obtained at the same time. Therefore, the terminal needs to obtain the third self-capacitance value through the data processing unit in real time at this time.

Similarly, in order to obtain the variation of the self-capacitance value of the second sensor, the terminal needs to obtain the self-capacitance value of the second sensor in real time as the fourth self-capacitance value in addition to the second self-capacitance value, and the terminal can further obtain the second self-capacitance variation only after the second self-capacitance value and the fourth self-capacitance value are obtained. Therefore, the terminal needs to obtain the fourth self-capacitance value through the data processing unit in real time at this time.

408. The terminal calculates a first self-capacitance variation according to the third self-capacitance value and the first self-capacitance value and/or calculates a second self-capacitance variation according to the fourth self-capacitance value and the second self-capacitance value;

after the terminal acquires the first self-capacitance value and the third self-capacitance value at the same time, the first self-capacitance variation can be calculated according to the third self-capacitance value and the first self-capacitance value. The specific calculation method may be to subtract the first self-capacitance value from the third self-capacitance value to obtain a difference, where the difference is the first self-capacitance value variation.

Similarly, after the terminal acquires the second self-capacitance value and the fourth self-capacitance value at the same time, the second self-capacitance variation can be calculated according to the fourth self-capacitance value and the second self-capacitance value. The specific calculation method may be to subtract the second self-capacitance value from the fourth self-capacitance value to obtain a difference, where the difference is the second self-capacitance value variation.

409. And the terminal determines the wearing state of the earphone according to the first self-capacitance variation and/or the second self-capacitance variation.

After the terminal acquires the first self-capacitance variation and/or the second self-capacitance variation, because the condition that the hand of the user is in contact with the ground of the internal circuit of the earphone but the earphone is not worn is compared with the condition that the user correctly wears the earphone to the ear, the caused first self-capacitance variation and/or second self-capacitance variation has obvious difference, so the terminal can determine the wearing state of the earphone according to the first self-capacitance variation and/or second self-capacitance variation. Wherein, the wearing state of the earphone comprises an unworn state and a worn state.

Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a flow of another embodiment of the method for detecting a state of an earphone according to the present application, applied to the earphone shown in fig. 2, where the another embodiment of the method for detecting a state of an earphone according to the present application includes:

501. the terminal acquires a first mutual capacitance variable quantity through a data processing unit;

the mutual capacitance is the capacitance between one sensing block and another sensing block, when an excitation signal is applied to one sensing block, the excitation signal can be sensed and received on the other sensing block due to the existence of the mutual capacitance, and the magnitude and the phase shift of the received signal are related to the frequency of the excitation signal and the magnitude of the mutual capacitance. Two sensors are needed for mutual capacitance detection, one for sending detection signals and one for receiving signals. The amplitude of the received signal will vary as the magnitude of the mutual capacitance varies. When a human body approaches, the human body can influence an electric field between the two mutual capacitance sensors, and the mutual capacitance value is reduced.

When a user approaches the earphone, no matter the user wears the earphone on the ear or the user touches the ground of the exposed internal circuit of the earphone with a hand, the change of the mutual capacitance value between the first sensor and the second sensor is caused, at the moment, the terminal can acquire the first mutual capacitance change amount through the data processing unit of the earphone, and the first mutual capacitance change amount is the change amount of the mutual capacitance value between the first sensor and the second sensor.

502. The terminal judges whether to trigger a proximity event of the earphone according to the first mutual capacitance variation, if so, step 503 is executed;

after the terminal obtains the first mutual capacitance variation through the data processing unit of the earphone, it may be determined whether to trigger a proximity event of the earphone according to the first mutual capacitance variation, where the proximity event is an event that a person approaches the earphone, and if the terminal determines that the proximity event occurs, step 503 may be executed. If the approach event of the earphone is not triggered, on the premise that the equipment works normally, the condition that the earphone is touched to the ground of an internal circuit by a user does not exist naturally, so when the terminal determines that the approach event is not triggered, the step of acquiring the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit is not necessarily executed, and only when the approach event is determined to be triggered, the step of acquiring the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit is executed.

503. The terminal acquires a first self-capacitance variation and/or a second self-capacitance variation through the data processing unit;

when a proximity event triggering the headset is determined, this time including a number of situations, such as when the user is correctly wearing the headset to his ear, when the user's hand touches the ground of the internal circuit exposed by the headset, and so on. The terminal needs to acquire more information to determine the specific state of the headset after determining the proximity event triggering the headset, and therefore the terminal acquires the first self-capacitance variation and/or the second self-capacitance variation through the data processing unit. The first self-capacitance variation is a variation of the self-capacitance of the first sensor, and the second self-capacitance variation is a variation of the self-capacitance of the second sensor.

504. The terminal determines whether the first self-capacitance variation is greater than or equal to a first threshold and/or whether the second self-capacitance variation is greater than or equal to a second threshold, if yes, step 505 is executed;

after obtaining the first self-capacitance variation and/or the second self-capacitance variation, the terminal may compare the first self-capacitance variation with a first threshold and compare the second self-capacitance variation with a second threshold, respectively, and may perform step 505 according to the following three cases:

1. the first self-capacitance variation is greater than or equal to a first threshold;

2. the second self-capacitance variation is greater than or equal to a second threshold;

3. the first self-capacitance variation is larger than or equal to a first threshold, and the second self-capacitance variation is larger than or equal to a second threshold.

In practical application, the terminal distinguishes two cases, namely the case that the user correctly wears the earphone on the ear and the case that the user grips the earphone and the hand touches the ground of the internal circuit of the earphone, from the variation of the mutual capacitance value caused by other cases through the first mutual capacitance variation, but cannot distinguish the two cases through the first mutual capacitance variation, and at the moment, the terminal can distinguish the two cases through the first self-capacitance variation and/or the second self-capacitance variation. When the user wears the earphone on the ear correctly, the distance between the human body and the first sensor or the second sensor is reduced, the human body is equivalent to the ground, and the distance between the human body and the ground is reduced from infinity to close proximity, so that the self-capacitance value of the first sensor or the second sensor is obviously increased. And for the condition that the user holds the earphone and touches the ground of the internal circuit of the earphone with the hand, the ground of the internal circuit is communicated with the human body, which is equivalent to communicating the ground of the internal circuit with the ground, but the first sensor or the second sensor is far away from the ground of the internal circuit, even if the ground of the internal circuit is communicated with the ground, the increment of the self-capacitance value of the first sensor or the second sensor caused by the communication is not large, and is even difficult to detect. Therefore, a value can be preset as the first threshold value to distinguish between a case where the user wears the headphone correctly on the ear and a case where the user grips the headphone and touches the ground of the internal circuit of the headphone with the hand, and the amount of change in the self-capacitance value of the first sensor is different from that caused by the other cases. Similarly, a value may be preset as the second threshold value to distinguish between a case where the user wears the headphone correctly on the ear and a case where the user grips the headphone and touches the ground of the internal circuit of the headphone with the hand, and the amount of change in the self-capacitance value of the second sensor is different from that caused by the other cases.

In practical applications, the terminal may detect the first self-capacitance variation alone, may detect the second self-capacitance variation alone, and may detect the first self-capacitance variation and the second self-capacitance variation simultaneously, which is not limited herein.

505. The terminal determines that the earphone is in a wearing state;

the terminal may determine that the headset is in a worn state after determining that the first self-capacitance variation is greater than or equal to a first threshold and/or the second self-capacitance variation is greater than or equal to a second threshold.

506. The terminal judges whether hand pressing exists or not through the pressure sensor, if yes, step 507 is executed;

after determining that the headset is in the worn state, the terminal may detect whether the user takes the headset off so that the headset is in a non-worn state. To detect whether the headset is switched from the worn state to the unworn state, the terminal first needs to determine whether there is hand pressure through the pressure sensor, and if it is determined that there is hand pressure, step 507 may be performed.

Further, in order to achieve the purpose of saving power, when the headset is in a worn state and hand pressure detection is performed, if hand pressure is not detected, low-frequency detection can be performed, the detection frequency is low, and once hand pressure is detected, high-frequency detection is switched to.

507. The terminal acquires a third mutual capacitance value between the first sensor and the second sensor in real time;

after the terminal determines that the hand pressure exists, a third mutual capacitance value between the first sensor and the second sensor can be acquired in real time.

508. The terminal calculates a second mutual capacitance variation according to the third mutual capacitance value and the second mutual capacitance value;

after the third mutual capacitance value is obtained, the terminal may calculate a second mutual capacitance variation according to the third mutual capacitance value and the second mutual capacitance value, specifically, may subtract the second mutual capacitance value from the third mutual capacitance value to obtain a difference, and use the difference as the second mutual capacitance variation.

509. The terminal determines whether the second mutual capacitance variation is greater than or equal to a fourth threshold, if so, step 510 is executed, and if not, step 506 is executed again;

after the terminal obtains the second mutual capacitance variation, it may be determined whether the second mutual capacitance variation is greater than or equal to a fourth threshold, and if it is determined that the second mutual capacitance is greater than or equal to the fourth threshold, step 510 may be executed; if it is determined that the second mutual capacitance value is less than the fourth threshold value, step 506 may be performed again.

510. And the terminal determines that the earphone is in a non-wearing state.

If the second mutual capacitance variation is greater than or equal to the fourth threshold, the terminal may determine that the headset is switched from the worn state to the unworn state, and the headset is currently in the unworn state.

In this embodiment, when it is determined that hand pressing exists, the terminal acquires a third mutual capacitance value between the first sensor and the second sensor, calculates a second mutual capacitance variation by combining the second mutual capacitance value, and after it is determined that the second mutual capacitance variation is greater than or equal to a fourth threshold, may determine that the earphone is in a non-wearing state, otherwise, continues to perform the determination of whether hand pressing exists and the subsequent steps. In practical application, in the process that a user grips an earphone worn on an ear with a hand, the terminal can detect hand pressing, the terminal can acquire a third mutual capacitance value and calculate a second mutual capacitance variation, but the hand of the user is close to the earphone, the hand of the user can cut off electric field lines between the first sensor and the second sensor, the second mutual capacitance variation is very small or even 0, the fourth threshold cannot be larger than or equal to, and the terminal cannot judge that the earphone is converted into a non-wearing state. Once the user releases the headset, for example, when the user puts the headset on a desktop and the hand pressure disappears, the second mutual capacitance variation also increases and is greater than or equal to the fourth threshold, and at this time, the terminal may determine that the headset is switched from the worn state to the unworn state.

In this embodiment, except that the wearing state that can detect the earphone is changed from the non-wearing state to the wearing state, can also further detect the earphone and change into the non-wearing state at the wearing state, after the user takes off the earphone, can in time close the music broadcast or the bluetooth connection etc. of earphone, be favorable to for the earphone power saving. Meanwhile, the user does not need to manually disconnect the earphone from other equipment, convenience is provided for the user, and user experience is improved.
