For example, a neck-band wireless headset may play media data for a user such as music, recordings, sounds in video files, etc.; under the scenes of telephone, audio call and video call, the method can play an incoming call prompt tone and voice data of a call opposite terminal, acquire the voice data of a user and send the voice data to the mobile phone; in a game scene, background music, game prompt tones, team-friend voice data and the like can be played, and voice data of a user is collected and sent to the mobile phone; under the WeChat voice message scene, the voice message can be played, and voice data recorded by a user is collected and sent to the mobile phone; under the scenes of a voice assistant and the like, the voice data of the user can be collected and sent to the mobile phone.

The following embodiments are described taking as an example a scenario in which a user plays music using a mobile phone and a neck-band wireless headset.

When the mobile phone and the neck belt type wireless earphone are used for listening to music, the first Bluetooth chip in the neck belt type wireless earphone and the mobile phone can be connected in a Bluetooth pairing mode. After the user starts the music playing service through the mobile phone, for example, referring to fig. 6, through the bluetooth connection, the user can enjoy music using the neck-band wireless headset.

When the neck strap type wireless earphone is normally used for listening to music, the first interface and the second interface are plugged together, the first Bluetooth chip in the neck strap type wireless earphone can receive audio data sent by a mobile phone through Bluetooth, and the processor can call the audio management module to transmit the audio data received by the mobile phone to the first earplug through the second connecting line, the battery box and the first connecting line and transmit the audio data to the second earplug through the first interface, the second interface and the third connecting line. In one arrangement, the processor may invoke the audio management module to send the left channel signal to the left earpiece and the right channel signal to the right earpiece. In another scheme, the processor may invoke the audio management module to send the same audio data to the left ear plug and the right ear plug, the left ear plug playing the left channel signal, and the right ear plug playing the right channel signal.

Under the condition that the neck strap type wireless earphone needs to be charged, such as the electric quantity is low or the neck strap type wireless earphone is shut down due to the exhaustion of the electric quantity, the first interface can be separated from the second interface, and the first interface and/or the second interface can charge the neck strap type wireless earphone.

It should be noted that, in the embodiment of the present invention, the separation of the first interface from the second interface means that the first interface and the second interface are pulled out, the first interface is completely exposed, and the first interface is electrically disconnected from the second interface.

For example, in one case, a user can unplug a first interface and a second interface that are plugged together, so that the first interface is completely exposed and the first interface is electrically disconnected from the second interface; in another case, a switch is arranged on the neck strap type wireless earphone, when a user presses the switch, the first interface and the second interface are bounced open, so that the first interface is completely exposed, and the first interface is electrically disconnected with the second interface; in another case, the user instructs to separate the first interface and the second interface on the mobile phone which sends audio data of music to the neckband type wireless earphone, the mobile phone sends a separation instruction to the neckband type wireless earphone after detecting the instruction operation of the user, and the neckband type wireless earphone responds to the separation instruction to automatically flick the first interface and the second interface, so that the first interface is completely exposed, and the first interface is electrically disconnected with the second interface.

After the first and second interfaces are separated, the neck-band wireless headset may include a first headset portion 403 and a second headset portion 404 as shown in fig. 4. Wherein the first earphone part may include a first earphone, a first connection line, a battery case, a second connection line, and a first part of the wire control case, which are electrically connected in sequence. The first portion of the drive-by-wire cartridge may include a control module electrically connected to the second connection line, and a first interface electrically connected to the control module. Thus, the first interface is also electrically connected to the second connection line. The second earphone portion may include a second earplug, a third cord, and a second portion of the cord control box electrically connected in sequence. The second portion of the drive-by-wire cartridge may include a second interface.

The first interface and the second interface may be different pluggable interfaces. For example, the first interface is a male connector and the second interface is a female connector. In the following embodiments, the first interface is a male connector (see interface 401 in fig. 4) of a USB Type-C connector (abbreviated as USB-C), and the second interface is a female connector (see interface 402 in fig. 4) of the USB-C connector.

In one embodiment, the first interface (i.e., the male portion of the USB-C connector) may be electrically connected to an external power source to charge the first battery after the first interface is separated from the second interface. When the first interface is electrically connected with the external power supply, the current input by the external power supply flows into the first interface and flows into the first battery in the battery box through the control module and the second connecting wire, so that the first battery is charged.

For example, the first interface can be directly plugged into a female terminal of a USB-C connector arranged on an external power supply such as a mobile phone, an ipad, a mobile power supply, a power plug or other electronic equipment for charging. Like this, need not carry and connect extra charging wire and special power, the second connecting wire and the first connecting wire of neck strap formula wireless headset itself just can regard as the charging wire, and cell-phone or other portable electronic equipment just can regard as the power to can be simply, convenient, charge for neck strap formula wireless headset's first battery fast. Therefore, the neck strap type wireless earphone can be conveniently charged even when it is difficult to connect to a power source during traveling on a train, an airplane, an automobile, outdoors, or the like.

In particular, the first interface may be plugged into an electronic device being used in conjunction with a neck-strap wireless headset for charging, which may reduce the number of devices that are interconnected (including wired and wireless connections) and reduce the number of devices that a user may need to carry around during mobility. For example, in the scenario shown in fig. 6, compared with the case where the first interface is inserted into another electronic device or a power plug such as an ipad or a mobile power supply for charging, as shown in fig. 7A, the number of the devices connected to each other can be reduced by inserting the first interface into a mobile phone for charging, and a user does not need to carry the ipad or the mobile power supply during moving, but only needs to carry the neck strap type wireless headset or carry the neck strap type wireless headset and the mobile phone.

In the following, the first interface is inserted into the mobile phone for charging when the neck strap type wireless headset and the mobile phone are used. The first interface may be implemented in various ways to charge the first battery of the first earphone part via the mobile phone.

For example, in one scheme, when the first interface (i.e., the male connector of the USB-C connector) is plugged into the female connector of the USB-C connector of the mobile phone, the processor may send the device type (e.g., the headset type) to the mobile phone through the first interface, and the mobile phone charges the first battery through the first interface after determining that the accessed device is the headset type.

In another scheme, after the first interface is inserted into the female terminal of the USB-C connector of the mobile phone, the mobile phone may compare the voltage of the battery of the mobile phone with the voltage of the first battery connected to the first interface. If the voltage of the mobile phone battery is higher than that of the first battery, the mobile phone can charge the first battery through the first interface; if the voltage of the mobile phone battery is lower than that of the first battery, the mobile phone does not charge the first battery.

In another scheme, after the first interface is inserted into the female terminal of the USB-C connector of the mobile phone, the mobile phone may compare the voltage of the battery of the mobile phone with the voltage of the first battery connected to the first interface. If the voltage of the mobile phone battery is higher than that of the first battery, the mobile phone can charge the first battery through the first interface; if the voltage of the mobile phone battery is lower than the voltage of the first battery, the mobile phone charges the first battery through the first interface after the voltage of the first battery is increased.

In another scheme, after the first interface is inserted into a female connector of a USB-C connector of the mobile phone, the mobile phone may compare the voltage of the mobile phone battery with a preset threshold. Generally, when the battery is sufficiently charged, the voltage of the battery is higher, for example, the voltage of the battery of the mobile phone may be 4.2V when the battery is sufficiently charged; when the battery charge decreases, the voltage of the battery also decreases. Therefore, if the voltage of the mobile phone battery is higher than the preset threshold (for example, may be 3.7V), it may indicate that the electric quantity of the mobile phone battery is sufficient, and the mobile phone may charge the first battery through the first interface; if the voltage of the mobile phone battery is lower than the preset threshold value, the electric quantity of the mobile phone battery is insufficient, and the mobile phone can not charge the first battery.

In yet another scheme, when the first interface is plugged into the female connector of the USB-C connector of the mobile phone, referring to fig. 7A, the mobile phone may display a prompt interface 71 on the current interface to prompt the user, or the mobile phone may prompt the user through an application (App), or the mobile phone may prompt the user through voice to determine whether to charge the accessed neck-band wireless headset. After detecting an operation of the user indicating charging (for example, detecting that the user clicks the control 72 or detecting a voice instruction of the user, etc.), the mobile phone charges the first battery through the first interface.

In another scheme, after the first interface is inserted into a female connector of a USB-C connector of the mobile phone, the user may press the control 2 on the neck strap type wireless headset, the neck strap type wireless headset sends a charging request to the mobile phone, and the mobile phone charges the first battery through the first interface after receiving the charging request.

In yet another aspect, after the first interface is plugged into the female connector of the USB-C connector of the mobile phone, the user can instruct the mobile phone to charge the neck strap wireless headset through the microphone of the mobile phone, and after detecting the instruction, the mobile phone charges the first battery through the first interface.

In another scheme, after the first interface is plugged into a female connector of a USB-C connector of the mobile phone, the user can instruct the mobile phone to charge the neck strap wireless headset through a microphone of the neck strap wireless headset. The processor sends the indication information to the mobile phone through the first interface, or the processor sends the indication information to the mobile phone through the first Bluetooth chip; and after receiving the indication information, the mobile phone charges the first battery through the first interface.

In some embodiments, after the first interface is plugged into the handset, in addition to charging the first battery, it may be determined whether the first bluetooth chip of the neck strap wireless headset has been bluetooth paired with the handset before. If the Bluetooth pairing is not performed, the first Bluetooth chip can be triggered to perform Bluetooth pairing with the mobile phone, so that when a subsequent user wants to perform Bluetooth communication with the mobile phone by using the first Bluetooth chip, the subsequent user can directly perform Bluetooth connection and Bluetooth communication on the paired basis without performing Bluetooth pairing when the user needs to use the Bluetooth communication.

For example, referring to fig. 7B, the process of triggering bluetooth pairing may include: 701. after the first interface is inserted into the mobile phone, if the processor of the neck strap type wireless headset determines that the processor supports the hardware to trigger the Bluetooth pairing function, the processor can control the first interface to send first information to the mobile phone, wherein the first information is used for indicating that the neck strap type wireless headset supports the hardware to trigger the Bluetooth pairing function. 702. After the mobile phone receives the first information, if the mobile phone determines that the mobile phone also supports the function of triggering Bluetooth pairing by hardware, the mobile phone sends second information to the neck belt type wireless earphone through the first interface so as to inform the neck belt type wireless earphone that the mobile phone also supports the function of triggering Bluetooth pairing by hardware. 703. After receiving the second information, the neck strap wireless headset may send information such as a bluetooth address (e.g., MAC address) of the first bluetooth chip to the mobile phone. 704. The historical matching information of the mobile phone stores the Bluetooth address of the device matched with the mobile phone, and the mobile phone can determine whether the mobile phone is matched with the first Bluetooth chip according to whether the historical matching information comprises the Bluetooth address of the first Bluetooth chip. 705. If the mobile phone is not paired with the first Bluetooth chip, the mobile phone can prompt the user whether to perform Bluetooth pairing with the inserted equipment. 706. If the mobile phone detects that the user indicates the operation of pairing with the inserted device, the mobile phone can enter a Bluetooth pairing mode. 707. The cell phone can instruct the neck strap wireless headset to enter a Bluetooth pairing mode through the first interface. 708. The mobile phone can directly carry out wireless Bluetooth pairing with the first Bluetooth chip according to the Bluetooth address of the first Bluetooth chip acquired through the first interface. Wherein, the process that this bluetooth paired can follow current bluetooth agreement, the embodiment of the utility model provides a do not restrict this. 709. After the Bluetooth pairing is completed, the user can be prompted to be successfully paired with the Bluetooth through the mobile phone and/or the neck belt type wireless earphone. In addition, the mobile phone can also display the names, Bluetooth addresses and other related information of the two successfully paired devices.

It should be noted that, when the above 701-709 is executed, the earphone is kept powered on, and in some embodiments, in 702, if the mobile phone determines that the mobile phone itself does not support the function of triggering bluetooth pairing by hardware, the steps after 702 are not executed, and the process of inserting the first interface into the mobile phone for charging is executed. Alternatively, in 704, the handset determines that it has already been paired with the headset before 701, and then the steps after 704 are not executed, and the aforementioned process of inserting the first interface into the handset for charging is executed. Or after 709, the process of charging by inserting the first interface into the mobile phone is executed. The specific process of charging is not repeated, and the earphone can be kept on or off during charging.

That is to say, by inserting the first interface into the mobile phone, the bluetooth pairing between the mobile phone and the first bluetooth chip can be triggered by hardware. Compared with the process of triggering Bluetooth pairing through wireless software such as wireless scanning in the prior art, the process of triggering Bluetooth pairing through hardware can save complex operations such as user indication entering a Bluetooth pairing mode and selection of equipment to be paired, and the Bluetooth pairing process is simpler and quicker.

In addition, after the first interface and the second interface are separated, at least the first earphone part in the neck strap type wireless earphone can be continuously used while charging is carried out through the first interface. Thus, when listening to music using a mobile phone and a neck strap type wireless earphone, even at home, when a power socket is available, the user can avoid inconvenience caused by long expectation of using the neck strap type wireless earphone beside the power socket when the mobile phone is inserted into the first interface for charging. During the journey, insert the cell-phone through with first interface and charge, can charge when using cell-phone and neck belt formula wireless headset, avoid neck belt formula wireless headset to need additionally to connect the inconvenience that portable power source caused.

When charging is performed through the first interface after the first interface and the second interface are separated, in one scheme, referring to fig. 7A, the first earplug which is connected with the first interface can be continuously used; the second earpiece, which is separate from the first interface, cannot be used further because power cannot be supplied. At this time, the neckband type binaural wireless earphone becomes a monaural earphone.

Specifically, the first interface may receive audio data of music sent by the mobile phone through a connection (i.e., a wired connection) between the first interface and the mobile phone, the processor calls the audio management module to send the audio data to the first ear plug, the first ear plug plays the audio data, and the first earphone portion at this time may be used as a wired earphone. Or when the processor determines that the channel quality of the bluetooth wireless connection between the processor and the mobile phone is good (for example, higher than or equal to a preset value), the first bluetooth chip may receive the audio data in a wireless communication manner, the processor calls the audio management module to send the audio data to the first earpiece, and the first earpiece plays the audio data; when the processor determines that the channel quality of the bluetooth wireless connection with the handset is poor (e.g., below a preset value), the first interface receives audio data of the music in a wired connection and the first earpiece plays the audio data.

Among them, there may be various parameters for representing the channel quality, such as one or more of a packet loss rate, an error rate, a signal-to-noise ratio, a quality of service (QoS) parameter, a Channel Quality Indicator (CQI) parameter, and the like. In the process of carrying out Bluetooth communication between the neck strap type wireless earphone and the mobile phone, the first Bluetooth chip can acquire the channel quality parameters through the antenna and report the channel quality parameters to the processor. The processor may determine the quality of the channel based on the channel quality parameter.

In this arrangement, the second earplug ceases to operate after the first and second interfaces are separated. After the first interface is inserted into the mobile phone, the processor controls the first earphone part to be powered off, the mobile phone can stop playing music and record a playing point at which the playing is stopped, after a user indicates that the first earphone part is powered on, the first earphone starts to work, the mobile phone continues to send audio data of the music to the first earphone part from the playing point, and the user can continue to enjoy the music through the first earphone; or after the first interface is inserted into the mobile phone, the first earphone part is not powered off, and the first earphone continues to play music after the first interface is inserted into the mobile phone; or before the first interface is inserted into the mobile phone, if the first earplug plays the left channel signal or the right channel signal in the binaural signal, after the first interface is inserted into the mobile phone, the processor enables the first earplug to play the monophonic signal by calling the audio management module, so as to improve the user experience.

After the first interface and the second interface are separated, when charging is carried out through the first interface, in another scheme, the first earplug connected with the first interface can be normally used; and, can embed second bluetooth chip and second battery in the second earplug, the second battery can be for the power supply of second earphone part, and the second earplug in the second earphone part also can be used.

Specifically, after the first interface and the second interface are separated, when the first interface is not electrically connected with the charging device, if the first earphone part is not electrically connected with the second earphone part, the second battery may supply power to the second earphone part; the second battery may provide power to the second earphone portion and the first earphone portion if the first earphone portion is electrically connected to the second earphone portion.

When the first interface and the second interface are not separated, in one case, the first earplug and the second earplug can share the first Bluetooth chip; in another case, the first earpiece uses the first bluetooth chip to communicate wirelessly with the mobile phone, and the second earpiece uses the second bluetooth chip to communicate wirelessly with the mobile phone. After the first interface and the second interface are separated, the first earplug uses the first Bluetooth chip to perform wireless communication with the mobile phone, and the second earplug uses the second Bluetooth chip to perform wireless communication with the mobile phone.

Wherein, first bluetooth chip and second bluetooth chip can have been joined in marriage when leaving the factory and have been right, mutually keep the bluetooth address of other side in first bluetooth chip and the second bluetooth chip. The first Bluetooth chip and the second Bluetooth chip can establish Bluetooth connection according to the Bluetooth address of the other party. Or the first Bluetooth chip and the second Bluetooth chip are separated from the second interface at the first interface and are in pairing connection when the second earplug is used in a Bluetooth mode.

After the first interface and the second interface are separated, when the first interface is used for charging, the first earplug and the second earplug can be matched for use in a binaural mode, and the first earplug and the second earplug play music synchronously. For example, referring to fig. 8, the same user wears a first ear bud and a second ear bud simultaneously, the second ear bud includes a second bluetooth chip 801 and a second battery 802, and the first ear bud and the second ear bud synchronously play left and right channel signals of stereo music. Specifically, the first earplug can be connected with the first bluetooth chip, and the second earplug can be connected with the bluetooth chip of the mobile phone through the second bluetooth chip in a forwarding, monitoring or dual-transmission manner, so that music can be played synchronously. For the related description of the dual-hair connection scheme, reference may be made to related descriptions in utility model documents with utility model numbers PCT/CN2018/118783, PCT/CN2018/118730, and PCT/CN2018/118791, which are not described herein again.

Alternatively, the first and second earplugs may each be used in a monaural mode. For example, referring to fig. 9, different users use different earplugs to interface with different cell phones. For example, the current user continues to enjoy music using the first earpiece and the current cell phone; the second earplug is connected with the Bluetooth chip of another mobile phone through the second Bluetooth chip, and another user uses the second earplug and another mobile phone to make and receive calls.

Or, the first earphone part can be used as a wired earphone when the first earphone part receives and plays the audio data of the music through the wired connection between the first interface and the mobile phone. Or when the channel quality of the Bluetooth wireless connection between the first earphone and the mobile phone is good, the first earphone receives audio data in a Bluetooth wireless communication mode so as to play music; when the channel quality of the Bluetooth wireless connection is poor, the audio data is received through the first interface in a wired connection mode so as to play music. The second earphone can be connected with the mobile phone through the second Bluetooth chip in a Bluetooth mode, so that audio data of music can be received and played in a wireless mode, and the second earphone portion can be used as a wireless earphone. At this time, the first and second earplugs can be used in a binaural mode to play music synchronously; the two-ear mode can also be used in the single-ear mode, and the embodiment of the present invention is not limited.

Under the condition that the second battery is arranged in the second earplug and the first interface is not separated from the second interface, according to a preset strategy, only the first battery provides electric quantity for the neck strap type wireless earphone, and the second battery does not provide electric quantity for the neck strap type wireless earphone, so that after the first interface is separated from the second interface, the second earplug can continue to work by using the electric quantity of the second battery; or the first battery firstly provides electric quantity for the neck belt type wireless earphone, and the second battery provides electric quantity for the neck belt type wireless earphone when the first battery is dead or low in electric quantity; alternatively, the first battery and the second battery may provide power to the neckband wireless headset simultaneously. Moreover, the first battery and the second battery can be charged mutually according to different voltages, so that the voltages of the two batteries tend to be balanced; alternatively, the second battery may charge the first battery when the charge of the first battery is depleted or is about to be depleted.

Under the condition that the second battery is arranged in the second earplug, when the first interface is separated from the second interface and is connected with the mobile phone to charge the first battery, the first earphone part can be electrically connected with the second earphone part through the connecting part, so that the second battery can be charged while the first battery is charged. And the second earplug can also be provided with a connecting terminal, a power supply control chip, a temperature detection circuit and the like which are matched with the second battery. In this case, the current input by the mobile phone flows from the first interface and flows into the first battery in the battery box through the control module and the second connecting wire, so as to charge the first battery; the current flowing from the first interface may also flow into the second earphone part via the connection between the first earphone part and the second earphone part and further into the second battery in the second earphone part, thereby also charging the second battery.

For example, referring to fig. 10, the back surface of the first earplug and the back surface of the second earplug are respectively provided with a magnetic attraction device (e.g., an induction elastic sheet), when the back surface of the first earplug and the back surface of the second earplug are close to each other, the first induction elastic sheet on the back surface of the first earplug and the second induction elastic sheet on the back surface of the second earplug are magnetically attracted to each other, that is, the first earphone portion is electrically connected with the second earphone portion, and the charging current flowing in the first interface can flow into the second battery in the second earplug through the electrical connection between the first induction elastic sheet and the second induction elastic sheet, so as to charge the second battery.

For another example, the first interface is electrically connected to the first plug, the second interface is electrically connected to the second plug, and the first plug and the second plug are detachably connected. When the first interface and the second interface are not separated, the first plug connector and the second plug connector can be plugged together to keep electric connection, and can also be separated to disconnect the electric connection. After the first interface is separated from the second interface, the first plug connector and the second plug connector are plugged together, and the charging current flowing into the first interface can flow into the second battery in the second earplug through the first plug connector and the second plug connector which are electrically connected, so that the second battery can be charged.

For another example, the neck strap wireless headset may further include a jumper through which the first interface and the second interface are electrically connected. After the first interface is separated from the second interface, the charging current flowing into the first interface can flow into the second interface through the jumper wire and further flow into the second battery in the second earplug, so that the second battery can be charged.

It will be appreciated that the first earphone part and the second earphone part may also be electrically connected by means of a snap or the like to charge the first battery in the first earphone part and the second battery in the second earphone part via the first interface. The first induction elastic sheet, the second induction elastic sheet, the jumper, the first plug connector, the second plug connector, the buckle and other parts are connecting parts between the first earphone part and the second earphone part.

It should be noted that, after the first interface is separated from the second interface, when the first interface is used for charging, if the first earphone portion and the second earphone portion are electrically connected, the connection manner between the two earphone units is usually limited, the first earplug and the second earplug are sucked together or the distance that the first earplug and the second earplug can be stretched between the first earplug and the second earplug is limited, so that a user can only wear one earplug into an ear, that is, the user can only select to use the first earplug or the second earplug. However, both the electrically connected first and second earpieces can receive and play audio data. If the extendable distance between the first and second earpieces is long (e.g. by a jumper connection between the two earpiece units), the user may also use the first and second earpieces simultaneously.

When the user uses the first and/or second ear buds, the first and/or second ear buds can receive audio data through the connection (i.e. the wired connection) between the first interface and the mobile phone so as to play music; the first Bluetooth chip and/or the second Bluetooth chip can receive audio data in a wireless communication mode so as to play music; and when the channel quality of the Bluetooth wireless connection is poor, the audio data is received through the first interface in a wired communication mode so as to play music.

In other schemes, the first interface may also be connected to other electronic devices or power supplies through an adapter or a patch cord, so as to charge the first battery and/or the second battery. For example, the first interface (i.e., the male connector of the USB-C connector) may be connected to a charging device provided with a male connector via a patch cord having female connectors at both ends of the USB-C connector, thereby charging the first battery and/or the second battery.

In another embodiment, the second interface electrically connects to an external power source to charge a second battery of the second earpiece after the first interface is separated from the second interface. When the second interface is electrically connected with an external power supply, the current flowing from the second interface can flow into the second battery in the second earplug through the third connecting wire, so that the second battery is charged. For example, the second interface may be plugged into an external power source to charge the second battery.

In some embodiments, after the second interface is plugged into the external power source, in addition to charging the second battery, it may be determined whether the second bluetooth chip has been bluetooth paired with the external power source before, similar to the process shown in fig. 7B. If the Bluetooth pairing is not performed, the second Bluetooth chip can be triggered to perform Bluetooth pairing with the external power supply, so that when a subsequent user wants to perform Bluetooth communication with the external power supply by using the second Bluetooth chip, the Bluetooth connection and the Bluetooth communication can be directly performed on the paired basis, and the user does not need to perform Bluetooth pairing when needing to use the Bluetooth communication.

Specifically, the second interface (i.e., the female terminal of the USB-C connector) may be connected to a male terminal of the USB-C connector provided on the external power source, or connected to the mobile power source, the power plug, or other electronic devices through a charging line, an adapter, a patch cord, or the like, so as to charge the second battery.

In a scene of playing music by using the mobile phone, the second earphone can receive and play audio data of the music sent by the mobile phone through the wired connection between the second interface and the mobile phone, and the second earphone part is equivalent to a wired earphone; or, the second earphone can also receive and play the audio data of the voice sent by the mobile phone in a wireless connection mode through the second bluetooth chip, and the second earphone part at this time is equivalent to a wireless earphone. Alternatively, the processor may determine the channel quality of the bluetooth connection and switch between the wired communication mode and the wireless communication mode according to the channel quality.

In this embodiment, the first earphone part and the second earphone part may be electrically connected by the connection part, so that when the power supply is connected through the second interface, the second battery in the second earphone part may be charged, and the first battery in the first earphone part may also be charged. In this case, when the second interface is electrically connected to the external power source, the current flowing from the second interface may flow into the second battery in the second earpiece through the third connection line, thereby charging the second battery; the current flowing from the second interface may also flow into the first earphone part through the connection member and further into the first battery in the first earphone part, thereby charging the first battery.

For example, referring to fig. 11, the first earphone portion and the second earphone portion can be electrically connected through a magnetic attraction device on the back of the first earphone and the second earphone, and the second interface is connected with the mobile power supply 1102 through a charging cord 1101 so as to receive a charging input. Alternatively, the first earphone part and the second earphone part may be electrically connected by a jumper between the first interface and the second interface; alternatively, the first earphone part and the second earphone part can be electrically connected by means of a buckle or a plug and the like.

When the first and second ear pieces are electrically connected to each other by charging through the second interface after the first and second interfaces are separated, the first and second ear pieces are attracted together or have a limited distance to extend therebetween, which is limited by the connection between the two ear pieces, so that a user can use only one ear piece. If the distance between the first and second earplugs is relatively long, the user may also use the first and second earplugs simultaneously. Likewise, when the user uses the first earplug and/or the second earplug, the first earplug and/or the second earplug can receive the audio data through the second interface in a wired connection mode so as to play music, can also receive the audio data through the first Bluetooth chip and/or the second Bluetooth chip in a wireless communication mode so as to play music, and can also switch between wired communication and wireless communication according to the channel quality.

In another embodiment, after the first interface is separated from the second interface, the charging can be performed through the first interface and the second interface at the same time.

For example, in one arrangement, referring to fig. 12, the first earphone portion and the second earphone portion are electrically disconnected, the first interface connects the handset to charge the first battery, and the second interface connects the portable power source to charge the second battery. In this case, the current input to the first interface by the mobile phone flows into the first battery, and the current input to the second interface by the portable power source flows into the second battery.

In another scheme, the first earphone part and the second earphone part are electrically connected through connecting parts such as an induction spring, a jumper, a buckle or a plug and the like, and are electrically connected with an external power supply through the first interface and the second interface to perform multi-path charging on the first battery and the second battery. In this case, a part of the current input from the external power supply to the first interface flows into the first battery, and the other part of the current flows into the second earphone part through the connecting member and further flows into the second battery in the second earphone part; a part of current input from the external power supply to the first charging interface flows into the second battery, and the other part of current flows into the first earphone part through the connecting part and further flows into the first battery in the first earphone part. When the maximum charging current of the battery is fixed, each path of charging current can be smaller through multi-path charging, so that the heating value during charging can be reduced, and the charging efficiency is improved.

Illustratively, referring to fig. 13, the first earpiece and the second earpiece are magnetically connected, the first interface receives a charging input through the mobile phone, and the second interface receives a charging input through the mobile power source. For another example, referring to fig. 14, the first interface and the second interface are connected by a jumper 1401, the first interface receives a charging input through a mobile phone, and the second interface receives a charging input through a mobile power supply.
