Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

References herein to "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Referring to fig. 1, a schematic diagram of an implementation environment including a wireless headset 110 and a headset case 120 according to an exemplary embodiment of the present application is shown.

The wireless earphone 110 is a portable electronic device with a listening function, and the wireless earphone 110 may be a single-ear wireless earphone or a double-ear wireless earphone, where the single-ear wireless earphone refers to that the wireless earphone is connected with the terminal in a wireless manner; the wireless earphone of ears divide into left ear and right ear, all is connected through wireless mode between this left ear and the right ear, between left and right ear and the terminal to the earphone can be simultaneously with terminal connection use, also can be alone with terminal connection use.

In one possible implementation, the wireless headset 110 has a bluetooth connection function, and the wireless headset 110 communicates with the terminal through a bluetooth connection.

The earphone box 120 is a device having a storage function and a charge/discharge function, at least one storage position is provided in the earphone box 120, the storage position is used for storing the wireless earphone 110, the number of the storage positions is related to whether the wireless earphone 110 is monaural or binaural, for example, the wireless earphone 110 is monaural, and only one storage position of the earphone box is provided. Meanwhile, pins are arranged on the wireless earphone 110 and the earphone box 120, and the pins which are coupled when the two are contacted 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 two.

In one possible application scenario, the wireless headset 110 needs to perform a box-in detection to determine whether the wireless headset 110 is in a box-in 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, when the wireless earphone is detected in the case of the wireless earphone, as shown in fig. 2, a micro switch 203 is disposed at the bottom of the wireless earphone 202, and when the wireless earphone 201 is placed in the earphone case 202, the micro switch 203 is turned on by touching the micro switch 203, so as to generate a trigger signal 204, and the earphone case 202 receives the trigger signal, that is, it is determined that the wireless earphone 201 is in the case-in state.

Obviously, after the earphone box detection method provided by the related technology is used for a long time, foreign matters possibly exist in the earphone box, and the problem of poor contact of the micro switch possibly occurs, so that the box 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 present application, the structure of the original earphone box is improved, so that the whole flow of in-box detection 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 the earphone box 302 performs the box-in detection, an audio signal 305 is played by the speaker 304, and when the wireless earphone 301 receives the audio signal 305 through a microphone 303, it is determined that the earphone box is in the box-in state. Compared with the prior art that the box entering detection is realized by means of the micro switch, the wireless earphone determines whether the box entering state is realized by determining whether the audio signal sent by the earphone box is received or not, so that the box entering erroneous judgment 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 relevant box entering operation.

It should be noted that, in the above embodiment, only the case detection of the single-ear wireless earphone is taken as an example for description, and in other possible embodiments, the case detection may be performed by the left-ear wireless earphone and the right-ear wireless earphone simultaneously, and accordingly, the earphone case may include two accommodating positions, and speakers are respectively disposed at bottoms of the two accommodating positions, which is not limited in this implementation.

Optionally, the position of the speaker inside the earphone box may be opposite to the position of the wireless earphone microphone in the accommodating state (i.e. the speaker inside the earphone box is opposite to the wireless earphone microphone), so as to improve the sound receiving effect of the wireless earphone microphone and further improve the accuracy of the in-box detection.

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

For convenience of description, the following embodiments will be schematically illustrated taking a wireless earphone as a single-ear wireless earphone and a speaker disposed at the bottom of an earphone box as an example.

Referring to fig. 5, a flowchart of a method for detecting a headphone set in a case according to an exemplary embodiment of the present application is shown. The embodiment will be described by taking an example that the earphone in-box detection method is used in an implementation environment shown in fig. 3, and the method includes:

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

Since the earphone box needs to continuously transmit the audio signal through the speaker at the time of the in-box detection, which increases the power consumption of the earphone box, the on of the speaker should take into consideration the factor of whether the in-box detection is currently required. In the embodiment of the application, when the earphone box is detected to be in the box opening state, it is determined that box entering detection is needed.

Optionally, the earphone box detects the mode that self is in the open box state, can set up the component that can produce the magnetic field such as magnet at the lid edge of earphone box, set up hall switch at the box body edge of earphone box, and hall switch's position is relative with the position of magnet on the lid under the earphone box closed state, when earphone box is in the closed box state, magnet is close to hall switch, hall switch can output low potential voltage (low level) or the signal of closing, when earphone box is in the open box state, magnet keeps away from hall switch, hall switch output high potential voltage (high level) or the signal of opening. Schematically, 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 box opening operation 603 is performed, the magnet 605 is far away from the hall switch 604, the hall switch 604 generates a high level signal 606, and when the earphone box receives the high level signal 606, the earphone box is confirmed to be in the box opening state.

Alternatively, a hall switch can be arranged at the edge of the box cover of the earphone box, and a magnet is correspondingly arranged at the edge of the box body of the earphone box.

Alternatively, magnets can be arranged on the box cover and the box body of the earphone box, when the earphone box is in a closed box state, the two magnets are coupled, and when the earphone box is in an open box state, the two magnets are decoupled. 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 in-box detection. Speakers can be classified into different kinds according to different operating principles, for example: the type of speaker is not limited in this embodiment, such as an electric type, an electrostatic type, an electromagnetic type, and a piezoelectric type.

In one possible embodiment, before the in-box operation is performed, the earphone box is in a closed state, and when the earphone box is switched from the closed state to the open state, in-box detection is required, at which time the earphone box starts the speaker. The earphone box detects that the earphone box is in an open box state, so that 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 speaker, and the preset audio signal is used for the wireless earphone to perform box-in detection.

The preset audio signal may be a continuous sound wave signal with a fixed frequency, for example, a continuous sound wave signal with a frequency of 20 KHZ; or a continuous periodically varying acoustic signal, i.e. a frequency that varies periodically with 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, in order to avoid noise interference to a user, the audio signal with the frequency above 20KHZ can be selected.

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

In one possible embodiment. When the earphone box is in an open box state, a preset audio signal is played through a loudspeaker, so that the wireless earphone can carry out box-in detection. Alternatively, the earphone box may continuously play the audio signal through the speaker, or may play the audio signal at periodic intervals.

In step 503, the wireless headset receives a first audio signal via the microphone.

The microphone is a transducer for converting sound signals into electric signals, and is applied to the wireless earphone, and can receive the voice of a user and also can receive other environment audio signals. In a normal state, a microphone on the wireless earphone 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, a corresponding operation is performed.

In step 504, if the first audio signal matches the preset audio signal, the wireless earphone is determined to be in the in-box state.

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

The preset audio signal may be stored in the wireless earphone (for example, a built-in memory of the wireless earphone) in advance, after the wireless earphone 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 earphone is determined to be in a box-in state.

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

In step 505, when the wireless earphone is in the in-box state, a in-box operation is performed, and the in-box operation at least includes entering a standby state.

In one possible implementation manner, when the wireless earphone is in the in-box state, that is, enters the standby state, since the wireless earphone may be a single-ear wireless earphone or a dual-ear wireless earphone, the wireless earphone 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 exit from the working state before entering the box. For example, the wireless earphone is playing music before being put into the box, and when the wireless earphone confirms that the box is put into the box, the playing of the music is stopped. Alternatively, when the wireless headset is in a standby state, the wireless headset may be disconnected 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 binaural wireless earphone, that is, the wireless earphone is divided into a left ear earphone and a right ear earphone, in one possible implementation manner, when a user uses the left ear earphone and the right ear earphone of the wireless earphone at the same time, the wireless earphone can distinguish a master-slave relationship between the left ear earphone and the right ear earphone according to the time of outputting the box, that is, the first-output box is a master earphone, and the second-output box is a slave earphone, so that when the left earphone and the right earphone of the wireless earphone work at the same time, the distinction of the master-slave relationship is provided. Optionally, when the wireless earphone is in the standby state, the wireless earphone may exit the master-slave relationship state before entering the box, that is, there is no master-slave division, so as to redetermine the master-slave relationship after the next exiting of the box.

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

Since the main function of the earphone box is to charge the wireless earphone, the wireless earphone can be put into the box for charging itself. Optionally, when wireless earphone gets into box state, can pass through the pin with self electric quantity information and give the earphone box to the earphone box judges whether to satisfy wireless earphone's demand of charging according to wireless earphone's electric quantity information, for example, when the electric quantity of earphone box is insufficient makes wireless earphone fully charged, 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.

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

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

In one possible implementation, the wireless earphone may transmit the in-box information to the earphone box through the pin, so that the earphone box determines that the wireless earphone is in the in-box state, and further stops playing the preset audio signal.

Optionally, after the wireless earphone is in the box-in state, the earphone box can be switched from the box-out state to the box-in state, and the earphone box can determine that the wireless earphone is in the box-in state through detecting that the earphone box is in the box-in state, for example, when the earphone box is in the box-in state, the magnet is close to the hall switch, the hall switch can output a low-level signal, and when the earphone box receives the low-level signal, the wireless earphone is determined to be in the box-in state.

Alternatively, the earphone box is determined to be in a closed box state by detecting that the two magnets are in a coupled state, so that the wireless earphone is determined to be in a box-in state.

To sum up, in the embodiment of the present application, a speaker is disposed inside the earphone box, a preset audio signal is played through the speaker, and when the wireless earphone receives the preset audio signal through the microphone, the wireless earphone is determined to be in a box-in state, so as to execute a related box-in operation. Compared with the prior art that the box entering detection is realized by virtue of the micro switch, the wireless earphone determines whether the wireless earphone is in the box entering state by determining whether the wireless earphone receives the preset audio signal sent by the earphone box, and can avoid the box entering erroneous judgment caused by poor contact of the micro switch, thereby improving the box entering detection accuracy and being beneficial to the wireless earphone to accurately execute the relevant box entering operation.

Since in normal circumstances, the microphone on the wireless earphone is turned on by default, other audio signals can be received at any time, in order to avoid that the wireless earphone recognizes the external audio signal as a preset audio signal sent by the earphone box by mistake, and the in-box state detection result is wrong, in a possible implementation manner, the earphone box can encode the preset audio signal, and accordingly, the in-box state can be determined only when the wireless earphone recognizes that the first audio signal contains the target encoding information.

Referring to fig. 7, a flowchart of a method for detecting a box entry according to another exemplary embodiment of the present application is shown. The method comprises the following steps:

in step 701, when the earphone box is in an open box state, the speaker is started.

The implementation of this step may refer to step 501, and this embodiment is not described herein.

In 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, 101010 type digital information is added into the audio signal to obtain a preset audio signal; the target coding information can also be another section of audio signal, and the audio signal is added into the original audio signal to obtain a preset audio signal. The present embodiment is not limited in the kind of target encoding information.

In one possible implementation, a digital signal processing (Digital Signal Processing, DSP) chip may be provided inside the earphone box, with which the audio signal is encoded. Alternatively, any component that can realize the function of encoding an audio signal, through which the audio signal is encoded, may be provided.

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

In step 704, the wireless headset receives a first audio signal via the microphone.

The embodiments of step 703 and step 704 described above may refer to step 502 and step 503, and this embodiment is not described herein.

In step 705, the wireless earphone decodes the first audio signal to obtain first encoded information contained in the first audio signal.

Because the preset audio signal is obtained by encoding the audio signal according to the target encoding information, the target encoding information can be stored in the wireless earphone in advance, the first audio signal is also 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 in-box detection; if the first audio signal contains the coding information, then whether the first audio signal is used for in-box detection can be determined by judging whether the coding information is matched with the target coding information.

In one possible implementation manner, if the wireless earphone is provided with a chip with a decoding function, the chip can be used for decoding the first audio signal; a DSP chip may be specially configured inside the wireless headset, so that the DSP chip may be used to decode the first audio signal; alternatively, any component that can realize the function of decoding the audio signal may be provided, and the first audio signal may be decoded by using the component.

In step 706, if the first encoding information matches the target encoding information, the wireless headset determines that the wireless headset is in the in-box state, and the preset audio signal is encoded according to the target encoding information.

In one possible implementation manner, the wireless earphone decodes the first audio signal to obtain the first encoded information contained in the first audio signal, and then the first encoded information and the target encoded information may be compared to determine whether the first encoded information and the target encoded information match, if the first encoded information and the target encoded information match, the wireless earphone determines that the wireless earphone is in the in-box state, otherwise, the wireless earphone determines that the wireless earphone is not in the in-box state.

Optionally, the microphone may receive N first audio signals, decode the N first audio signals respectively, and if the obtained N coding information matches the target coding, the wireless earphone determines that the wireless earphone is in an in-box state, where N is an integer and greater than or equal to 2. The accuracy of box entering detection can be improved through multiple times of matching, and the occurrence of accidental phenomenon is avoided.

In step 707, when the wireless earphone is in the in-box state, a in-box operation is performed, where the in-box operation at least includes entering a standby state.

The implementation of this step may refer to step 505, and this embodiment is not described herein.

In step 708, the wireless earphone sends the in-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 in-box information.

In one possible implementation, after the wireless earphone enters the box state, the pin on the wireless earphone and the pin on the earphone box are automatically coupled, and the wireless earphone can perform information interaction between the pin and the earphone box. Optionally, the wireless earphone may send the in-box information to the earphone box through a pin, so that after the earphone box receives the in-box information, playing of the preset audio signal may be stopped.

In step 709, the earphone box receives the in-box information sent by the wireless earphone through the pin.

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

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

The implementation of this step may refer to step 506, and this embodiment is not described herein.

In the embodiment of the application, the earphone box obtains the preset audio signal by encoding the target coding information, and 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 is in the box-in state or not is determined according to the matching result, the false identification of the wireless earphone can be avoided, and the box-in detection is more accurately carried out. The wireless earphone sends the box information to the earphone box through the pin, so that the earphone box stops sending preset audio signals according to the box information, the power consumption of the earphone box can be reduced, and unnecessary power consumption is avoided.

Because the preset audio signal played by the loudspeaker may penetrate through the earphone box, when the wireless earphone is in use and is close to the earphone box, the preset audio signal may be received, so that the wireless earphone is mistakenly identified as being in the box state, in order to avoid mistaken identification of the wireless earphone as being in the box state in use, in one possible implementation mode, the wireless earphone can acquire the use state of the wireless earphone, and when the wireless earphone receives the preset audio signal, the wireless earphone is in the non-wearing state, the wireless earphone is determined to be in the box state.

Illustratively, steps 705 and 706 may be replaced with steps 711, 712, and 713, as shown in FIG. 8, based on FIG. 7.

In step 711, a usage status of the wireless headset is obtained, where the usage status includes a wearing status and a non-wearing status.

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

The above-mentioned proximity sensor and capacitive sensor are taken as examples, and the detection use state is schematically described, and alternatively, the wireless earphone may be detected whether it is in a wearing state by using a triaxial accelerometer in combination with an optical sensor, which is not limited in this embodiment.

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

The implementation of this step may refer to step 705, and this embodiment is not described herein.

In step 713, if the first encoded information matches the target encoded information and the wireless headset is in the non-wearing state, then the first encoded information is determined to be in the in-box state.

In one possible embodiment, since the wireless headset should be in a non-wearing state before the in-box detection, when 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, it is determined to be in the in-box state.

In this embodiment, by adding the condition of judging the usage state, when the wireless earphone determines that the first encoded information is matched with the target encoded information and the wireless earphone determines that the wireless earphone is in the non-wearing state, the wireless earphone is determined to be in the box-in state, and therefore the situation that the wireless earphone is erroneously identified as the box-in state in the using process can be avoided, and accuracy of box-in detection is improved.

After the wireless earphone is put into the box, a series of information exchange may need to be performed between the wireless earphone and the earphone box, when the pins on the wireless earphone are coupled with the pins on the earphone box, the information exchange can be performed through the coupled pins, but the wireless earphone cannot be charged at the same time of the information exchange, if the information exchange is performed at the same time of charging, the charging efficiency may be affected, so that the charging time is prolonged, and therefore, in order to separate the charging from the information exchange, the information exchange can be realized through a mode of transmitting audio signals.

Referring to fig. 9, a flowchart of information interaction between the wireless earphone and the earphone box in the in-box state is shown. Step 901, obtaining the 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 method can also comprise the charging state of the earphone box, namely quick charging, continuous charging, trickle charging and the like, wherein the quick charging refers to the process that the battery of the wireless earphone can be charged to 80%; in a 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 charge state, the earphone box charges the wireless earphone by using tiny pulse current, so that the real saturation of a battery of the wireless earphone is ensured, and the service time of the wireless earphone is prolonged.

In one possible implementation, after the earphone box determines that the wireless earphone is already in the box and stops playing the preset audio signal, information interaction with the wireless earphone, that is, state information of the earphone box, may be prepared.

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

In one possible implementation, the earphone box may encode the earphone box state information through the DSP chip to obtain a second audio signal carrying the earphone box state information.

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

In one possible implementation, the earphone box plays the second audio signal through the speaker, so that the wireless earphone can still acquire the state information of the earphone box while being charged. Alternatively, the earphone box may play the second audio signal at regular intervals, for example, every 1 minute.

In step 904, the wireless headset receives a second audio signal from the headset box via the microphone.

When the wireless earphone enters the in-box state, the microphone on the wireless earphone is still turned on by default, so that the second audio signal can be received by the microphone to complete information interaction with the earphone box.

In step 905, the wireless earphone decodes the second audio signal through the DSP chip to obtain the earphone box status information.

Because the earphone box cannot directly interact with the terminal, 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 one possible implementation, when the wireless earphone receives the second audio signal sent by the earphone box, since the second audio signal is an analog signal, in order to facilitate information transmission of the wireless earphone, the second audio signal needs to be decoded to obtain a digital signal carrying the box state information of the earphone.

In step 906, the wireless headset sends headset box status information to the paired terminal, which is a terminal paired with the wireless headset.

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

In this embodiment, when the wireless earphone is in the in-box state, the earphone box plays the second audio signal through the speaker, at this time, the wireless earphone can receive the second audio signal through the microphone and analyze and obtain the earphone box state information contained in the second audio signal, so as to realize information interaction with the earphone box while charging, and avoid the influence of information interaction on charging efficiency. The state information of the earphone box can also be sent to the pairing terminal, so that a user can know the state information of the earphone box in time.

In one possible implementation, the manner in which the wireless earphone receives the audio signal through the microphone may also be used for out-of-box detection, so that the wireless earphone confirms the box and performs a corresponding out-of-box operation.

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

In step 1001, when the earphone box is switched from the closed box state to the open box state, a third audio signal is played through the speaker.

In the embodiment of detecting the open state of the earphone box, reference may be made to step 501, and this embodiment is not described herein.

Wherein the third audio signal is used for detecting the output box, and the third audio signal can be a continuous sound wave signal with a certain frequency, for example, a continuous sound wave signal with 20 KHz. Or a continuous periodically varying acoustic signal, i.e. a frequency that varies periodically with time, such as a sine wave.

Because the third audio signal can be transmitted to the outside of the earphone box through the earphone box, in order to avoid noise interference to the user, an audio signal with a frequency of 20KHZ or more can 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 audio signal.

When the wireless earphone is switched from the in-box state to the out-box state, the corresponding earphone box should also be switched from the out-box state to the open-box state, in a possible implementation manner, when the earphone box determines that the wireless earphone is in the in-box state and the earphone box is in the out-box state, the earphone box is switched from the out-box state to the open-box state, at this time, the wireless earphone may need to perform out-box detection, and the earphone box plays a third audio signal through the speaker.

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

The implementation of this step may refer to step 503, and this embodiment is not described herein.

In step 1003, if the wireless headset does not receive the third audio signal N consecutive times, it is determined to be in the out-of-box state.

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

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

In one possible implementation manner, when the wireless earphone is in the out-box state, i.e. enters the working state, since the wireless earphone may be a single-ear wireless earphone or a dual-ear wireless earphone, the wireless earphone 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, and music and the like can be played again.

If the wireless earphone is a binaural wireless earphone, that is, the wireless earphone is divided into a left ear earphone and a right ear earphone, in one possible implementation manner, the left ear earphone and the right ear earphone are simultaneously in a box-in state, after any earphone is out of a box, the wireless earphone can distinguish a master-slave relationship between the left ear earphone and the right ear earphone according to the time of the out-box, that is, the first-out box is a master earphone, and the second-out box is a slave earphone.

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

In one possible implementation, to reduce power consumption, the transmission of the third audio signal may be stopped after the earphone box determines that the wireless earphone has been out of box. The mode of determining the wireless earphone out of the box may 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 may receive the third audio signal in the process of outputting the box, and when the wireless earphone does not receive the third audio signal N times continuously, the wireless earphone is determined to be in the box outputting state. The method for judging the wireless earphone to be in the box-out state by determining that the third audio signal is not received is convenient for the wireless earphone to carry out corresponding box-out operation without manual operation of a user, and the using convenience of the wireless earphone can be improved.

In the above embodiments, the step of using the wireless earphone as the execution body may be implemented as the earphone-in-box detection method of the wireless earphone side alone, and the step of using the earphone box as the execution body may be implemented as the earphone-in-box detection method of the earphone box side alone, which is not described herein.
