When the earphone especially some special application scenes of TWS earphone, for example when using as the accessory of wearing type equipment such as VR, the earphone often need fix respectively in wearing type equipment's both sides, nevertheless wearing type equipment can not charge for the earphone, can not accomodate the earphone in addition when not using wearing type equipment at ordinary times yet, has caused the difficulty for user's use.

Therefore, the invention provides a split-type earphone box, which is applied to an earphone assembly, wherein the earphone assembly comprises a first earphone and a second earphone.

Referring to fig. 1, in an embodiment of the present invention, a split-type earphone box includes:

the earphone comprises a first charging box 10, wherein an accommodating cavity for accessing a first earphone is formed in the first charging box 10, and a first main control assembly 12 and a first working assembly 11 are arranged in the first charging box 10;

the first main control component 12 is configured to control the first working component 11 to be in a charging mode to charge the first headset when the first headset is accessed, and/or control the first working component 11 to be in a communication mode so that the first main control component 12 establishes a communication connection with the first headset through the first working component 11;

a second charging box 20, wherein an accommodating cavity for accessing a second earphone is arranged on the second charging box 20, and a second main control assembly 22 and a second working assembly 21 are arranged in the second charging box 20;

the second main control component 22 is configured to control the second working component 21 to be in a charging mode to charge the second headset when the second headset is connected, and/or control the second working component 21 to be in a communication mode so that the second main control component 22 establishes a communication connection with the second headset through the second working component 21;

a connector 30, the first charging box 10 for establishing electrical connection with the second charging box 20 via the connector 30;

the first main control assembly 12 is further configured to establish a communication connection with the second main control assembly 22 when the first charging box 10 is electrically connected with the second charging box 20 through the connector 30.

In this embodiment, the first main control component 12 can be implemented by a main controller, such as an MCU (micro controller unit), a DSP (Digital Signal processing) chip, an FPGA (Field Programmable Gate Array) chip, and the like. The first working assembly 11 and the second working assembly 21 may be composed of a battery, at least one switching circuit, and a charging circuit, so that the voltage of the battery can be converted into a charging voltage and then output, and the headset can enter a charging state when being connected.

In this embodiment, the connector 30 may be implemented by using a separate connector 30, for example, a flat cable with a connector or a connecting wire to establish electrical connection between the first charging box 10 and the second charging box 20, or may be directly disposed on the first charging box 10 or the second charging box 20, for example, a plurality of connecting ports including a plurality of connecting ends are disposed on the first charging box 10, and a connecting head having a structure corresponding to the connecting ports and including a plurality of connecting ends is disposed on the second charging box 20, so as to facilitate the use of a user without additionally carrying a connecting wire.

In this embodiment, the shape of the receiving cavity may be set according to the configuration of the earphone.

In this embodiment, after the first main control component 12 establishes a communication connection with the first headset/after the second main control component 22 establishes a communication connection with the second headset, data can be interacted with each other, for example, the power of the headset is read, or the headset is controlled to execute a corresponding program according to an externally accessed signal. And when the first charging box 10 is in a combined state with the second charging box 20 through the connector 30, data exchange between the first main control assembly 12 and the second main control assembly 22 can also be achieved, so that the first main control assembly 12 controls the first headset and the second headset at the same time.

It will be appreciated that in practical applications, the connection terminals of the earphone and the charging box are generally two (ground terminal and charging/communication terminal) or three (ground terminal, charging terminal, communication terminal).

Optionally, in an implementation, two connection terminals (a ground terminal and a charging/communication terminal) may be disposed in the accommodating cavity at the same time to adapt to the earphone with the two connection terminals. Taking the first charging box 10 as an example (the same applies to the circuit of the second charging box 20), when the first earphone is not used for communication, the first main control module 12 may control the corresponding charging circuit to start operating, and control the corresponding switch circuit to operate, so as to conduct the path between the output end of the charging circuit and the charging/communication end on the accommodating cavity (charging mode), and when the earphone needs to communicate, control the corresponding switch circuit to operate, so that the charging/communication end on the accommodating cavity only establishes an electrical connection path with the first main control module 12. Thus, when the first earphone is connected, the first charging box 10 can store, charge and communicate with the first earphone. When the first charging box 10 and the second charging box 20 are in a combined state through the connector 30, the first earphone box and the second earphone box can still normally charge the accessed first earphone and the accessed second earphone, and at this time, the first main control assembly 12 can communicate with the second main control assembly 22 through the connector 30 to realize mutual data interaction. In other words, the first master control assembly 12 can now acquire data from the second headset via the connector 30 and the second master control assembly 22, and send the data to the second headset via the connector 30 and the second master control assembly 22.

Optionally, in another embodiment, three corresponding connection ends may be simultaneously disposed in the accommodating cavity, or a first charging box 10 is taken as an example, when the first main control component 12 has a communication requirement, the first working component 11 is controlled to be in a communication mode, for example, a corresponding switch in the first control component is controlled to be in a closed state, so as to conduct a path between the first main control component 12 and the communication end in the accommodating cavity, so that when the first earphone is connected, the first main control component 12 establishes a communication connection with the first earphone through the first working component 11, and simultaneously, the first working component 11 may be controlled to be in a charging mode, so that the corresponding charging circuit works to output a charging voltage through the charging end, so that the charging operation can be performed when the first earphone is connected. When the two charging boxes are in a combined state through the connector 30, the charging box communication can still be performed on the connected earphones, and data can be exchanged between the first main control assembly 12 and the second main control assembly 22 as in the above embodiment, so that the first main control assembly 12/the second combined empty assembly can control the first earphone and the second earphone at the same time. Therefore, in a special use scene of the headset, for example, when the headset is used as an accessory of a head-mounted device, a user can respectively arrange the first headset box and the second headset box on two sides of the head-mounted device to respectively store two headsets and charge the headset, so that the requirement of the user on using the headset when the user uses the head-mounted device is met, and the convenience of the user in the special application scene is improved. Meanwhile, when the first charging box 10 and the second charging box 20 are connected through the connector 30, the requirement of the user for daily independent use of the earphone can be met, and the same function as that of a common earphone charging box is realized.

The split type earphone box of the present invention includes a first charging box 10, a second charging box 20, and a connector 30. The first charging box 10 is provided with a containing cavity for accessing a first earphone, the first charging box 10 is provided with a first main control assembly 12 and a first working assembly 11, the first main control assembly 12 is used for controlling the first working assembly 11 to be in a charging mode to charge the first earphone when the first earphone is accessed, and/or controlling the first working assembly 11 to be in a communication mode to enable the first main control assembly 12 to be in communication connection with the first earphone through the first working assembly 11; the second charging box 20 is provided with an accommodating cavity for accessing a second earphone, the second charging box 20 is provided with a second working assembly 21, and the second main control assembly 22 is used for controlling the second working assembly 21 to be in a charging mode to charge the second earphone when the second earphone is accessed, and/or controlling the second working assembly 21 to be in a communication mode to enable the second main control assembly 22 to establish communication connection with the second earphone through the second working assembly 21; a connector 30, the first charging box 10 for establishing electrical connection with the second charging box 20 via the connector 30; the first master control assembly 12 is also configured to establish a communication connection with the second master control assembly 22 when the first charging box 10 is electrically connected to the second charging box 20 via the connector 30. Therefore, in a special use scene of the headset, for example, when the headset is used as an accessory of a head-mounted device, a user can respectively arrange the first headset box and the second headset box on two sides of the head-mounted device to respectively store two headsets and charge the headset, so that the requirement of the user on using the headset when the user uses the head-mounted device is met, and the convenience of the user in the special application scene is improved. Meanwhile, when the first charging box 10 and the second charging box 20 are connected through the connector 30, the requirement of the user for daily independent use of the earphone can be met, so that the convenience of the user in using the split-type earphone box of the present invention is improved.

Referring to fig. 2, in an embodiment of the present invention, the first main control component 12 includes a first communication end for accessing the connector 30, and the first working component 11 includes:

a first battery 111;

the output end of the first switch circuit 112 is used for establishing an electrical connection path with the first earphone when the first earphone is connected, and the controlled end and the second input end of the first switch circuit 112 are respectively connected with the first main control assembly 12;

a first power management circuit 113, an input terminal of the first power management circuit 113 is connected to the first battery 111, and an output terminal of the first power management circuit 113 is connected to a first input terminal of the first switch circuit 112;

a first power management circuit 113, configured to output a charging voltage after performing overvoltage conversion on the battery voltage of the first battery 111;

a first switch circuit 112, configured to, when in a charging mode under the control of the first main control assembly 12, turn on a path between a first input terminal and an output terminal of the first switch circuit 112; alternatively, when the first main control component 12 is in the communication mode, the path between the second input terminal and the output terminal of the first switch circuit 112 is conducted, so that the first main control component 12 and the first headset establish a communication connection when the first headset is connected.

In this embodiment, the first power management circuit 113 may be implemented by using a charge management chip with a voltage conversion function, or by using the charge management chip and a DCDC circuit. The first switch circuit 112 may be implemented by a single-pole double-throw switch circuit, such as a single-pole double-throw relay and its peripheral control circuit, or a single-pole double-throw analog switch, so that the first switch circuit 112 can switch on/off a path between the first input terminal and the output terminal under the control of the first main control component 12.

Specifically, when the first main control assembly 12 does not need to communicate with the first earphone, the first main control assembly 12 controls the first switch circuit 112 to be in the charging mode, that is, controls the first switch circuit 112 to conduct the path between the first input terminal of the first switch circuit 112 and the output terminal SC1, at this time, if the first earphone is connected, the first power management circuit 113 may output the charging voltage to the first earphone through the output terminal SC1 of the first switch circuit 112 to charge the first earphone.

When the first main control component 12 needs to communicate with the first earphone, the first switch circuit 112 is controlled to be in the communication mode to conduct the path between the second input terminal of the first switch circuit 112 and the output terminal SC1, so that the first main control component 12 establishes a communication connection with the first earphone when the first earphone is connected.

It can be understood that, under the condition of no communication requirement, the first main control component 12 may also control the first switch circuit 112 to be in the communication module at intervals of preset access detection time (set by a developer), at this time, the first main control component 12 may send an inquiry signal, if the first headset is accessed, then an headset access response signal may be transmitted back, then the first main control component 12 may confirm that the current first headset is accessed when receiving the headset access response signal, and if the headset access response signal cannot be received within a certain time, then confirm that the current first headset is not accessed.

Through the above arrangement, no matter when the first charging box 10 and the second charging box 20 are used separately/jointly, the user can place the first earphone in the first charging box 10, so as to charge the first earphone while the first charging box 10 accommodates the first earphone, or perform communication interaction with the first earphone. The earphone can meet the requirements of a user on using the earphone on a head-mounted device in a special scene, and meanwhile, the requirement of the user on daily independent use of the earphone can be met, and the convenience of use of the user is further improved.

In an embodiment of the present invention, the second main control assembly 22 includes a second communication terminal for accessing the connector 30, and when the first charging box 10 is used for establishing an electrical connection with the second charging box 20 through the connector 30, the first communication terminal and the second communication terminal establish an electrical connection path;

a second switch circuit 212, configured to turn on a path between a first input terminal and an output terminal of the second switch circuit 212 when the second master control component 22 is in the charging mode; alternatively, when the second master control assembly 22 is in the communication mode, the path between the second input terminal and the output terminal of the second switch circuit 212 is turned on, so that the second master control assembly 22 and the second headset establish a communication connection when the second headset is connected.

In this embodiment, the second switch circuit 212 may be implemented by a single-pole double-throw switch circuit, such as a single-pole double-throw relay and its peripheral control circuit, or a single-pole double-throw analog switch, as in the first switch circuit 112 of the above-mentioned embodiment. The second power management circuit 213 may be implemented by using a charge management chip with a voltage conversion function, or may be implemented by using a charge management chip and a DCDC circuit, as in the first power management circuit 113 in the above embodiment.

Specifically, when the second master control assembly 22 has no communication requirement with the second earphone, the control will control the second switch circuit 212 to be in the charging mode, that is, control the second switch circuit 212 to conduct the path between the second input terminal of the second switch circuit 212 and the output terminal SC2, as in the control process of the first master control assembly 12 in the above embodiment, at this time, if the second earphone is connected, the second power management circuit 213 can output the charging voltage to the second earphone via the output terminal SC2 of the second switch circuit 212 to charge the second earphone.

Similarly, if the second main control module 22 needs to communicate with the second earphone, the second switch circuit 212 is controlled to be in the communication mode to conduct the path between the second input terminal of the second switch circuit 212 and the output terminal SC2, so that the second main control module 22 and the second earphone establish a communication connection when the second earphone is connected.

It can be understood that, under the condition of no communication requirement, the second main control assembly 22 also controls the second switch circuit 212 to be in the communication module at preset access detection time intervals (set by developers), at this time, the second main control assembly 22 sends out an inquiry signal, if the second headset is accessed, an headset access response signal is returned, and then the second main control assembly 22 can confirm that the current second headset is accessed when receiving the headset access response signal, and if the headset access response signal cannot be received within a certain time, then confirm that the current second headset is not accessed.

After the first charging box 10 and the second charging box 20 are electrically connected through the connector 30, the first communication terminal of the first main control assembly 12 is electrically connected to the second main control assembly 22 through the connector 30 and the second communication terminal, and at this time, the first main control assembly 12 can exchange data with the second main control assembly 22.

It is understood that the first master control assembly 12 is further configured to output a query signal via the first communication terminal every preset polling time interval;

the second main control assembly 22 is further configured to determine that the first charging box 10 is electrically connected to the second charging box 20 through the connector 30 when receiving the query signal through the second communication terminal, and output a response signal through the second communication terminal;

In the present embodiment, the preset polling time is set in advance by the developer during the development period and is stored in the first master component 12. After the first main control assembly 12 sends the query signal through the first communication terminal, if the corresponding feedback signal is not received through the first communication segment within the preset response time (it can be understood that the duration of the preset response time is slightly less than the duration of the preset polling time), the first main control assembly 12 considers that the first charging box 10 and the second charging box 20 are currently in the separated state. In this manner, the first and second

main control assemblies

12 and 22 can confirm whether the first charging box 10 is currently electrically connected to the second charging box 20 via the connector 30.

Through the arrangement, when the second charging box 20 in the split-type earphone box is in a split state, for example, when the second charging box is arranged on one side of the head-mounted device, the requirements of a user on storing the second earphone and charging the second earphone can be met, and the user can pick the second earphone conveniently at any time. Meanwhile, when the second charging box 20 is in a combined state with the first charging box 10 through the connector 30, all functions of a normal earphone charging box can be realized, so that the split charging box and two earphones can interact with each other. The invention not only meets the requirement of using the earphone on the head-wearing equipment under a special scene, but also meets the requirement of independently using the earphone in daily life, thereby further improving the convenience of using the earphone by the user.

the second main control component 22 is further configured to control the second switch circuit 212 to be in the communication mode every preset time interval, so as to obtain a second electric quantity signal transmitted by the second headset, and control the second indication module 23 to indicate the electric quantity of the second headset according to the second electric quantity signal.

It can be understood that the controller in the earphone can obtain the current battery capacity of the earphone from the capacity information output by the internal BMS module, and output a corresponding capacity signal when the earphone box requires its output capacity parameter.

In this embodiment, the first indication module 13 and the second indication module 23 may be implemented by RGB-LED lamps, after the first main control component 12 determines that the first earphone is connected, the first main control component 12 may control the first switch circuit 112 to be in the communication mode at preset time intervals (the first main control component 12 is pre-stored by research and development personnel in the research and development period), for example, 5S, 10S, and the like, so as to communicate with the connected first earphone and request the first earphone to output the first electric quantity signal, the first main control component 12 may determine the current battery electric quantity of the first earphone according to the first electric quantity signal output by the first earphone, and control the RGB lamps to light corresponding colors according to the current battery electric quantity, for example, the RGB lamps light red when below 20%, light blue when 20% -60%, light green when above 60%, and the like. Similarly, after the second main control component 22 determines that the second earphone is connected, the second main control component 22 may also adopt the same control process to obtain the second electric quantity signal from the second earphone, determine the current battery electric quantity of the second earphone according to the second electric quantity signal, and control the RGB lamp to light the corresponding color according to the current battery electric quantity.

For example, when the first and second headsets are connected and the first and

second charging boxes

10 and 20 are in the merging state, the user may press the key for a long time to make the first and second

main control assemblies

12 and 22 output bluetooth matching signals to the first and second headsets, so that the first and second headsets enter the bluetooth matching state.

Therefore, the split type earphone box provided by the invention can meet the requirements of a user when the user uses the earphone on a special scene, such as a head-wearing device, and can also meet the requirements of the user for daily independent use of the earphone, thereby further improving the convenience of use of the user.
