Meanwhile, pins are arranged on the wireless earphone 110 and the earphone box 120, and the pins coupled when the wireless earphone 110 and the earphone box 120 are in contact with each other can be used as a charging and discharging path between the wireless earphone 110 and the earphone box 120 or a path for information interaction between the wireless earphone 110 and the earphone box 120.

In one possible application scenario, the wireless headset 110 needs to perform an in-box detection to determine whether the wireless headset 110 is in an in-box state, so as to more accurately perform charging or information interaction between the wireless headset 110 and the headset box 120.

In the related art, a mode of touching a switch lightly may be adopted when the wireless headset is placed in the box for detection, as shown in fig. 2, a micro switch 203 is arranged at the bottom of the wireless headset 202, when the wireless headset 201 is placed in the headset box 202, the micro switch 203 is touched lightly, the micro switch 203 is turned on to generate a trigger signal 204, and the headset box 202 receives the trigger signal, that is, determines that the wireless headset 201 is in the box-in state.

Obviously, after the method for detecting the earphone in the box provided by the related technology is used for a long time, foreign matters may exist in the earphone box, the problem of poor contact of the microswitch may be caused, and the box-in detection of the earphone is affected.

In order to solve the problems in the related art, in the method provided by the embodiment of the application, the structure of the original earphone box is improved, so that the whole box-entering detection process is improved. Schematically, as shown in fig. 3, in the embodiment of the present application, a speaker 304 is disposed inside an earphone box 302, and when performing box entry detection, the earphone box 302 plays an audio signal 305 through the speaker 304, and when the wireless earphone 301 receives the audio signal 305 through a microphone 303, it is determined that the wireless earphone 301 is in a box entry state. Compared with the prior art, the box entering detection is realized by means of the micro switch, the wireless earphone determines whether the wireless earphone is in the box entering state or not by determining whether the audio signal sent by the earphone box is received or not, the box entering misjudgment caused by poor contact of the micro switch can be avoided, the box entering detection accuracy is improved, and the wireless earphone is facilitated to accurately execute the related box entering operation.

It should be noted that, in the foregoing embodiment, only the single-ear wireless headset in-box detection is taken as an example for description, in other possible embodiments, the left-ear wireless headset and the right-ear wireless headset may perform in-box detection at the same time, and correspondingly, the headset box may include two accommodating positions, and speakers are respectively disposed at bottoms of the two accommodating positions, which is not limited in this embodiment.

Optionally, the position of the speaker inside the earphone box can be opposite to the position of the wireless earphone microphone in the accommodating state (namely, the speaker inside the earphone box is right opposite to the wireless earphone microphone), so that the radio reception effect of the wireless earphone microphone is improved, and the accuracy of box detection is further improved.

Schematically, in a housed state, that is, when the wireless headset is placed in the headset case, as shown in fig. 4 (a), when the microphone 403 is disposed at the bottom of the wireless headset 401, correspondingly, the speaker 404 should be disposed at the bottom of the headset case 402; as shown in fig. 4 (B), if the microphone 403 is provided on the right side of the wireless headset 405, the speaker 404 should be provided on the right side surface of the headset case 406.

For convenience of description, the following embodiments are schematically illustrated by taking the wireless headset as a single-ear wireless headset and the speaker disposed at the bottom of the headset case as an example.

Referring to fig. 5, a flowchart of a headset in-box detection method according to an exemplary embodiment of the present application is shown. The embodiment is described by taking the earphone in-box detection method as an example for being used in the implementation environment shown in fig. 3, and the method includes:

step 501, when the earphone box is in the open box state, the speaker is started.

Since the headphone box needs to continuously transmit the audio signal through the speaker during the in-box detection, the power consumption of the headphone box is increased by this operation, and therefore, the turning on of the speaker should consider whether the in-box detection is currently required. In the embodiment of the application, the earphone box is determined to be required to be subjected to box entering detection when the earphone box is detected to be in the box opening state.

Optionally, the earphone box detects a mode that the earphone box is in an open box state, elements such as a magnet and the like capable of generating a magnetic field can be arranged at the edge of a box cover of the earphone box, a hall switch is arranged at the edge of a box body of the earphone box, the position of the hall switch is opposite to the position of the magnet on the box cover under the closed state of the earphone box, when the earphone box is in the closed box state, the magnet is close to the hall switch, the hall switch can output a low potential voltage (low level) or a closed signal, when the earphone box is in the open box state, the magnet is far away from the hall switch, and the hall switch outputs a high potential voltage (high level) or an open signal. Illustratively, as shown in fig. 6, a magnet 605 is disposed at an edge of a box cover 601 of the earphone box, a hall switch 604 is disposed at an edge of a box body 602 of the earphone box, when the magnet 605 is away from the hall switch 604 during the box opening operation 603, the hall switch 604 generates a high level signal 606, and when the earphone box receives the high level signal 606, it is determined that the earphone box is in the box opening state.

Optionally, a hall switch may be disposed at an edge of the box cover of the earphone box, and correspondingly, a magnet is disposed at an edge of the box body of the earphone box.

Optionally, magnets may be disposed on the box cover and the box body of the earphone box, the earphone box is in a closed state, the two magnets are coupled, and the two magnets are decoupled when the earphone box is in an open state. When the earphone box detects that the two magnets are decoupled, the earphone box is determined to be in an open box state.

The loudspeaker is a transducer device for converting an electrical signal into an acoustic signal, and is used for emitting an audio signal for box-in detection. Loudspeakers can be classified into different categories according to different operating principles, for example: the present embodiment is not limited to the type of speaker, and includes an electric type, an electrostatic type, an electromagnetic type, a piezoelectric type, and the like.

In a possible embodiment, before the box-entering operation is performed, the earphone box is in a box-closing state, when the earphone box is switched from the box-closing state to the box-opening state, the box-entering detection is required, and the earphone box starts the loudspeaker. The earphone box detects that the earphone box is in the open box state, the judgment mode of the loudspeaker is started, and unnecessary electric quantity consumption can be reduced.

Step 502, the earphone box plays a preset audio signal through a loudspeaker, and the preset audio signal is used for the wireless earphone to perform box-in detection.

Wherein, the preset audio signal may be a continuous sound wave signal with a fixed frequency, for example, a continuous sound wave signal with 20 KHZ; or may be a continuous periodically varying acoustic signal, i.e. a periodic variation of frequency over time, such as a sine wave.

Because the preset audio signal can be transmitted to the outside of the earphone box through the earphone box, the audio signal with the frequency above 20KHZ can be selected to avoid noise interference to a user.

Alternatively, the preset audio signal may be an audio signal set by the user, for example, a ring tone. The present embodiment does not limit the type of the audio signal.

In one possible implementation. When the earphone box is in the open-box state, the preset audio signal is played through the loudspeaker, so that the wireless earphone can be conveniently subjected to in-box detection. Optionally, the earphone box may continuously play the audio signal through the speaker, or may play the audio signal at periodic intervals.

Step 503, the wireless headset receives the first audio signal through the microphone.

The microphone is a transducer for converting a sound signal into an electric signal, is applied to the wireless headset, and can receive voice of a user and other environmental audio signals. In a normal state, a microphone on the wireless headset is turned on by default, so that an external audio signal can be received at any time, and after the microphone receives the audio signal, corresponding operation is executed.

In step 504, if the first audio signal matches the predetermined audio signal, the wireless headset is determined to be in a boxed state.

In a possible implementation manner, the wireless headset receives the first audio signal through the microphone, and since the first audio signal may be a preset audio signal sent by the headset box or other environmental audio signals, the wireless headset needs to check the audio signal to determine whether the first audio signal matches the preset audio signal.

The preset audio signal may be pre-stored in the wireless headset (for example, a built-in memory of the wireless headset), when the wireless headset receives the first audio signal, the first audio signal is matched with the preset audio signal, and if the first audio signal is matched with the preset audio signal, the wireless headset determines that the wireless headset is in a box-in state.

Optionally, the wireless headset may receive the first audio signal N times through the microphone, and after N times of matching, if the N times of matching results all indicate that the first audio signal matches the preset audio signal, the wireless headset determines that the wireless headset is in a box-entering state, where N is an integer and is greater than or equal to 2. The accuracy of the box detection can be improved through multiple matching, and accidental phenomena are avoided.

And 505, when the wireless earphone is in the box entering state, executing box entering operation, wherein the box entering operation at least comprises entering a standby state.

In a possible embodiment, when the wireless headset is in the in-box state, i.e. enters the standby state, since the wireless headset may be a single-ear wireless headset or a double-ear wireless headset, the wireless headset enters the standby state in two cases:

if the wireless earphone is a single-ear wireless earphone, when the wireless earphone is in a standby state, the wireless earphone can move back to the working state before entering or exiting the box. For example, the wireless headset plays music before entering the box, and stops playing music after the wireless headset confirms entering the box. Alternatively, when the wireless headset is in a standby state, the wireless headset may disconnect from the terminal after a predetermined time. For example, the predetermined time is 10 minutes, and when the wireless headset is determined to be in the box for 10 minutes, the connection with the terminal is disconnected.

If the wireless earphone is a dual-ear wireless earphone, namely the wireless earphone is divided into a left-ear earphone and a right-ear earphone, in a possible implementation mode, when a user uses the left earphone and the right earphone of the wireless earphone simultaneously, the wireless earphone can distinguish the master-slave relationship between the left earphone and the right earphone according to the time of box outlet, namely the first earphone is the master earphone and the second earphone is the slave earphone, so that the master-slave relationship is distinguished when the left earphone and the right earphone of the wireless earphone work simultaneously. Optionally, when the wireless headset is in the standby state, the wireless headset may exit from the master-slave relationship state before entering the case, that is, there is no master-slave relationship, so as to re-determine the master-slave relationship after the next cartridge exit.

Of course, when any one of the two-ear wireless earphones is in the in-box state, the in-box operation similar to that of the one-ear wireless earphone can be performed, and details are not described herein in this embodiment.

Since the earphone box mainly functions to charge the wireless earphone, the wireless earphone can be put into the box to charge the wireless earphone. Optionally, when wireless earphone got into the box state, can pass through the pin with the electric quantity information of self and transmit for the earphone box to the earphone box judges the demand of charging whether satisfying wireless earphone according to the electric quantity information of wireless earphone, for example, the electric quantity when the earphone box is not enough to make wireless earphone full of electricity, then the earphone box can remind the user through the colour of pilot lamp, so that the user charges for the earphone box in time.

Step 506, when the earphone box determines that the wireless earphone is in the box-in state, the preset audio signal is stopped playing.

Because the electric quantity of the earphone box is consumed when the preset audio signal is played, when the wireless earphone is in the box-in state, the preset audio signal does not need to be received to judge whether the wireless earphone is in the box-in state, and therefore when the earphone box determines that the wireless earphone is in the box-in state, the preset audio signal can be stopped being played.

In a possible implementation manner, the wireless headset may transmit the box-entering information to the headset box through the pin, so that the headset box determines that the wireless headset is in the box-entering state, and then stops playing the preset audio signal.

Optionally, after the wireless headset is in the box-entering state, the headset box can be switched to the box-closing state from the box-opening state, and the headset box can determine that the wireless headset is in the box-entering state by detecting that the headset box is in the box-closing state, for example, when the headset box is in the box-closing state, the magnet is close to the hall switch, the hall switch can output a low level signal, and when the headset box receives the low level signal, it is determined that the wireless headset is in the box-entering state.

Optionally, it may also be determined that the earphone box is in the closed box state by detecting that the two magnets are in the coupled state, and then it is determined that the wireless earphone is in the in-box state.

To sum up, in this application embodiment, set up the speaker in the earphone box, predetermine audio signal through this speaker broadcast, after wireless earphone received this predetermine audio signal through the microphone, then confirm to be in and go into the box state, and then carry out relevant box operation of going into. Compared with the prior art, the box entering detection is realized by means of the micro switch, the wireless earphone determines whether the wireless earphone is in the box entering state or not by determining whether the wireless earphone receives the preset audio signal sent by the earphone box or not, the box entering misjudgment caused by poor contact of the micro switch can be avoided, the accuracy of the box entering detection is improved, and the wireless earphone is facilitated to accurately execute the related box entering operation.

Because under the usual condition, the microphone on the wireless earphone is acquiescently opened, and other audio signals can be received at any time, so as to avoid the situation that the wireless earphone identifies the external audio signals as preset audio signals sent by the earphone box by mistake, and the detection result of the box-in state is incorrect, in a possible implementation mode, the earphone box can encode the preset audio signals, and correspondingly, only when the wireless earphone identifies that the first audio signals contain target coding information, the wireless earphone can be determined to be in the box-in state.

Referring to fig. 7, a flowchart of a method for in-cassette detection according to another exemplary embodiment of the present application is shown. The method comprises the following steps:

and step 701, when the earphone box is in an open box state, starting a loudspeaker.

Step 501 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.

And step 702, the earphone box encodes the audio signal according to the target encoding information to obtain a preset audio signal.

The target coding information may be regular digital information, for example, digital information of 101010 type is added to an audio signal to obtain a preset audio signal; the target coding information may also be another audio signal, and the audio signal is added to the original audio signal to obtain a preset audio signal. The present embodiment is not limited to the type of target encoded information.

In one possible implementation, a Digital Signal Processing (DSP) chip may be disposed inside the headphone case, and the audio Signal may be encoded by the DSP chip. Optionally, any component that can implement the function of encoding the audio signal may be provided, and the audio signal is encoded by the component.

In step 703, the earphone box plays a preset audio signal through a speaker.

Step 704, the wireless headset receives a first audio signal through the microphone.

The implementation of step 703 and step 704 may refer to step 502 and step 503, which is not described herein again.

Step 705, the wireless headset decodes the first audio signal to obtain first encoded information included in the first audio signal.

The preset audio signal is obtained by encoding the audio signal according to the target encoding information, so that the target encoding information can be stored in the wireless earphone in advance, the first audio signal is decoded after the wireless earphone receives the first audio signal, and if the first audio signal does not contain the encoding information, the first audio signal is determined not to be the audio signal for the in-box detection; if the first audio signal contains the coding information, whether the first audio signal is used for the in-box detection can be further determined by judging whether the coding information is matched with the target coding information.

In a possible implementation manner, if the wireless headset is provided with a chip with a decoding function, the chip can be used for decoding the first audio signal; or a DSP chip can be specially arranged in the wireless earphone, so that the DSP chip is utilized to decode the first audio signal; optionally, any component capable of implementing the function of decoding the audio signal may be provided, and the component is used to decode the first audio signal.

Step 706, if the first coding information matches the target coding information, the wireless headset is determined to be in a box-in state, and the preset audio signal is obtained according to the target coding information.

In a possible implementation manner, the wireless headset decodes the first audio signal to obtain first encoded information included in the first audio signal, and may compare whether the first encoded information matches the target encoded information, and if the first encoded information matches the target encoded information, the wireless headset determines that the wireless headset is in the in-box state, otherwise, the wireless headset determines that the wireless headset is not in the in-box state.

Optionally, the microphone may receive the first audio signal N times, decode the N first audio signals respectively, and if the obtained N pieces of encoded information match the target code, the wireless headset determines that the wireless headset is in a box-in state, where N is an integer and is greater than or equal to 2. The accuracy of the box detection can be improved through multiple matching, and accidental phenomena are avoided.

And step 707, when the wireless headset is in the box-in state, executing box-in operation, wherein the box-in operation at least comprises entering a standby state.

Step 505 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.

And 708, the wireless earphone sends the box information to the earphone box through the pin, and the earphone box is used for stopping playing the preset audio signal according to the box information.

In a possible implementation manner, after the wireless headset enters the box-in state, the pin on the wireless headset and the pin on the headset box can be automatically coupled, and the wireless headset can perform information interaction with the headset box through the pin. Optionally, the wireless headset may send the box information to the headset box through the pin, so that the headset box may stop playing the preset audio signal after receiving the box information.

And step 709, the earphone box receives the box entering information sent by the wireless earphone through the pin.

In a possible implementation manner, after the wireless headset enters the box-in state, the pin on the headset box is automatically coupled with the pin on the wireless headset, and the headset box can charge the wireless headset through the pin and can also perform information interaction with the wireless headset. Optionally, the earphone box may receive box entering information sent by the wireless earphone through the pin, so as to execute a corresponding operation according to the box entering information, for example, stop playing the preset audio signal.

And step 710, the earphone box determines that the wireless earphone is in the box-in state according to the box-in information, and stops playing the preset audio signal.

Step 506 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.

In the embodiment of the application, the earphone box obtains the preset audio signal by encoding the target coding information, the wireless earphone decodes the received first audio signal, and matches the coding information obtained by decoding with the target coding information, so that whether the earphone box is in a box entering state or not is determined according to a matching result, the false recognition of the wireless earphone can be avoided, and the box entering detection can be carried out more accurately. The wireless earphone sends box information into to the earphone box through the pin to the earphone box stops sending according to the box information of going into and predetermines audio signal, can reduce the power consumption of earphone box, avoids the unnecessary consumption.

Because the preset audio signal that the speaker broadcast probably pierces through the earphone box, when wireless earphone in the use to when being close to with the earphone box, probably receive this preset audio signal, thereby lead to wireless earphone misidentification to the box state of going into, in order to avoid wireless earphone misidentification to the box state of going into in the use, in a possible implementation, wireless earphone can acquire the user state of self, receive this preset audio signal when wireless earphone, and wireless earphone is in the non-wearing state, just can confirm to be in the box state of going into.

Illustratively, on the basis of fig. 7, as shown in fig. 8, step 705 and step 706 may be replaced by step 711, step 712 and step 713.

Step 711, acquiring the use state of the wireless headset, where the use state includes a wearing state and a non-wearing state.

The wireless earphone can detect the use state through the proximity sensor, and the proximity sensor can adopt an infrared induction mode, namely, whether the wireless earphone is in a wearing state can be determined by detecting infrared radiation generated by a human body. The wearing state can also be detected through the capacitive sensor, namely when the wireless headset is worn on the ear of a user, the coupling capacitance can be generated, so that the output value of the capacitive sensor is changed, and the wireless headset can detect the wearing state according to the change of the output value.

The proximity sensor and the capacitive sensor are taken as examples to schematically illustrate the detection of the use state, and optionally, a three-axis accelerometer may be used in combination with the optical sensor to detect whether the wireless headset is in the wearing state, which is not limited in this embodiment.

In step 712, the wireless headset decodes the first audio signal to obtain the first encoded information contained in the first audio signal.

Step 705 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.

In step 713, if the first encoded information is matched with the target encoded information and the wireless headset is in a non-wearing state, it is determined that the wireless headset is in a box-entering state.

In one possible embodiment, since the wireless headset should be in a non-wearing state before the wireless headset is in the box detection, the wireless headset is determined to be in the box state after the wireless headset determines that the first encoded information matches the target encoded information and the wireless headset determines to be in the non-wearing state.

In this embodiment, by adding the condition of determining the use state, when the wireless headset determines that the first encoded information matches the target encoded information and the wireless headset is determined to be in the non-worn state, the wireless headset is determined to be in the in-box state, so that the wireless headset can be prevented from being mistakenly identified as the in-box state in the use process, and the accuracy of in-box detection is improved.

After the wireless earphone is put into the box, a series of information exchanges may need to be performed between the wireless earphone and the earphone box, after the pin on the wireless earphone is coupled with the pin on the earphone box, information interaction may be performed through the coupled pin, but while the information interaction is performed, the earphone box may not charge the wireless earphone at the same time, if the information interaction is performed while charging, charging efficiency may be affected, thereby prolonging charging time, and therefore, in order to separate charging from information interaction, the information interaction may be achieved through a mode of transmitting an audio signal.

Referring to fig. 9, a flowchart illustrating information interaction between the wireless headset and the headset case in the in-box state is shown. Step 901, obtaining earphone box state information.

The state information of the earphone box may include a remaining power of the earphone box, for example, the remaining power of the earphone box is 60%; the charging state of the earphone box, namely, fast charging, continuous charging, trickle charging and the like, wherein the fast charging refers to a process of charging the battery of the wireless earphone to 80%; in the continuous charging state, the charging current of the earphone box is gradually reduced, so that the battery of the wireless earphone can be ensured to enter a full critical state; in the trickle charging state, the earphone box charges the wireless earphone by using a tiny pulse current, so that the battery of the wireless earphone is ensured to be really saturated, and the service life of the wireless earphone is prolonged.

In a possible implementation manner, after the earphone box determines that the wireless earphone is placed in the box and stops playing the preset audio signal, information interaction with the wireless earphone can be prepared, namely, state information of the earphone box is obtained.

And step 902, the earphone box encodes the earphone box state information through the DSP chip to obtain a second audio signal.

In a possible implementation manner, the headphone case may encode the headphone case state information through the DSP chip to obtain a second audio signal carrying the headphone case state information.

Step 903, the earphone box plays the second audio signal through the speaker.

In a possible implementation manner, the earphone box plays the second audio signal through the speaker, so that the wireless earphone can still obtain the state information of the earphone box while charging. Optionally, the headphone case may play the second audio signal at regular time, for example, once every 1 minute.

Step 904, the wireless headset receives a second audio signal sent by the headset box through the microphone.

When the wireless earphone enters the box-in state, the microphone on the wireless earphone is still opened by default, so that the information interaction with the earphone box can be completed by receiving the second audio signal through the microphone.

And step 905, the wireless earphone decodes the second audio signal through the digital signal processing DSP chip to obtain earphone box state information.

Because the earphone box can not directly perform information interaction with the terminal, the state information of the earphone box needs to be transmitted to the terminal through the wireless earphone, so that a user can check the state information of the earphone box at any time. In a possible implementation manner, when the wireless headset receives the second audio signal sent by the headset box, since the second audio signal is an analog signal, in order to facilitate information transmission of the wireless headset, the second audio signal needs to be decoded to obtain a digital signal carrying state information of the headset box.

Step 906, the wireless headset sends the headset box state information to the paired terminal, which is the terminal paired with the wireless headset.

In one possible embodiment, the wireless headset may transmit the digital signal carrying the status information of the headset case to the counterpart terminal in the form of a data packet (e.g., a bluetooth data packet), so that the user can directly view the status information of the headset case on the terminal.

In this embodiment, when wireless earphone is in the box-in state, the earphone box plays second audio signal through the speaker, and at this moment, wireless earphone can receive this second audio signal through the microphone to the analysis obtains the earphone box state information that contains in the second audio signal, thereby realizes carrying out the information interaction with the earphone box when charging, avoids the two to carry out the influence of information interaction to charging efficiency. The state information of the earphone box can be sent to the pairing terminal, so that a user can know the state information of the earphone box in time.

In a possible embodiment, the mode that the wireless earphone receives the audio signal through the microphone can also be used for out-box detection, so that the wireless earphone confirms out-box, and accordingly corresponding out-box operation is executed.

Referring to fig. 10, a flowchart of a headphone out-of-box detection method according to an exemplary embodiment of the present application is shown.

And 1001, when the earphone box is switched from the closed box state to the open box state, playing a third audio signal through a loudspeaker.

Step 501 may be referred to in the implementation of detecting the open state of the earphone box, and this embodiment is not described herein again.

The third audio signal is used for out-of-box detection, and the third audio signal may be a continuous sound wave signal with a certain frequency, for example, a continuous sound wave signal with 20 KHZ. Or may be a continuous periodically varying acoustic signal, i.e. a periodic variation of frequency over time, such as a sine wave.

Since the third audio signal can be transmitted to the outside of the headphone case through the headphone case, in order to avoid noise interference to the user, an audio signal with a frequency greater than or equal to 20KHZ may be selected.

Alternatively, the third audio signal may be the same as the preset audio signal. The present embodiment does not limit the type of the audio signal.

When the wireless earphone is switched to the box-out state from the box-in state, correspondingly, the earphone box should also be switched to the box-out state from the box-closed state, in a possible implementation manner, when the earphone box determines that the wireless earphone is in the box-in state, and after the earphone box is in the box-closed state, the earphone box is switched to the box-out state from the box-closed state, at this moment, the wireless earphone may need to be subjected to box-out detection, and then the earphone box plays a third audio signal through the loudspeaker.

In step 1002, the wireless headset receives a third audio signal through the microphone.

The step 503 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.

Step 1003, if the wireless headset does not receive the third audio signal for N consecutive times, determining that the wireless headset is in the out-of-box state.

In a possible implementation manner, the wireless headset may receive the third audio signal at least 1 time during the process of going out of the box, continue to receive the third audio signal after receiving the third audio signal, and determine that the wireless headset is in the out-of-box state if the third audio signal is not received N consecutive times. Wherein N is an integer and is greater than or equal to 2.

And 1004, when the wireless earphone is in the box-out state, executing box-out operation, wherein the box-out operation at least comprises entering a working state.

In a possible implementation manner, when the wireless headset is in the out-of-box state, i.e. enters the working state, since the wireless headset may be a single-ear wireless headset or a double-ear wireless headset, the wireless headset enters the working state in two cases:

if the wireless earphone is a single-ear wireless earphone, when the wireless earphone is in a working state, the wireless earphone can be connected with the terminal again, music can be played again, and the like.

If the wireless earphones are double-ear wireless earphones, namely the wireless earphones are divided into a left-ear earphone and a right-ear earphone, in a possible implementation mode, the left earphone and the right earphone are in a box-in state at the same time, after any earphone is taken out of the box, the wireless earphones can distinguish the master-slave relation between the left-ear earphone and the right-ear earphone according to the time of taking out the box, namely the earphone which is taken out of the box firstly is the master earphone, and the earphone which is taken out of the box later is the slave earphone.

Of course, when any one of the two-ear wireless earphones is in the out-box state, the out-box operation similar to that of the one-ear wireless earphone can be performed, and details are not described herein in this embodiment.

In one possible embodiment, in order to reduce power consumption, the transmission of the third audio signal may be stopped after the earphone box determines that the wireless earphone has come out of the box. The mode of determining that the wireless earphone is taken out of the box can be that the earphone box is switched from an open box state to a closed state.

In this embodiment, when the earphone box is switched from the closed box state to the open box state, the third audio signal is played through the speaker, the wireless earphone can receive the third audio signal in the process of going out of the box, and when the wireless earphone does not receive the third audio signal for N consecutive times, the earphone is determined to be in the out-of-box state. The wireless earphone is judged to be in the out-of-box state by determining the mode that the third audio signal is not received, so that the wireless earphone can perform corresponding out-of-box operation, manual operation of a user is not needed, and the use convenience of the wireless earphone can be improved.

It should be noted that, in the foregoing embodiments, the step of using the wireless headset as the execution main body may be implemented separately as a method for detecting that the headset is plugged into the box of the wireless headset side, and the step of using the headset box as the execution main body may be implemented separately as a method for detecting that the headset is plugged into the box of the headset box side, which is not described herein again.
