The invention provides a head-wearing wireless earphone.

The head strip in the Wireless headset is detachably connected with the headset body, the application of a main headset, particularly a Bluetooth headset, is more and more extensive along with the rapid development of the headset technology, the latest TWS (True Wireless Stereo) headset is a typical product with good combination of intelligentization and Wireless trends in the main headset, and the TWS headset has a certain occupancy rate in the headset market by means of wearing freedom and good tone quality. The TWS headset is generally composed of a master headset and a slave headset, and a single headset can be used independently, that is, the two headsets can be used as both the master headset and the slave headset. The TWS earphone transmits the audio signal of the mobile phone to the master earphone through a Bluetooth link through a Bluetooth technology, and the master earphone transmits the audio data to the slave master earphone, so that the purpose of simultaneously playing two ears is achieved. That is, when the existing TWS headset wants to realize binaural simultaneous playing, it needs to pair the ears first. For the two paired main earphones, because the connection information of the pair of the main earphones to the ears exists, the connection between the pair of the main earphones and the ears can be directly carried out when the main earphones are used again.

The pairing control method for the primary earphone of the TWS bluetooth earphone to enter the pairing mode or release the pairing mode is roughly divided into two methods. The first method comprises the following steps: a key triggering mode is added on the earphone; and the second method comprises the following steps: and the charging box sends a pairing command to the earphone, and the earphone enters a pairing mode or a pairing releasing mode. However, the TWS bluetooth headset has a small size, and the way of adding keys to the headset not only affects the aesthetic property of the ID, but also causes many problems in terms of structure and electronic design. If the structural space of the earphone is small, keys cannot be added, the sealing performance of the earphone cannot be guaranteed due to the increased keys, and the like; and let the box that charges send for the earphone and pair when ordering, the box that charges will increase microprocessor and lead to and earphone communication, increased extra cost, and in pairing and removing at every turn and pairing need put into the box that charges, complex operation is unfavorable for user experience. In addition, the main earphone needs to be paired with an external terminal, the main earphone is generally divided into a main earphone and a secondary earphone, when the terminal is paired with the TWS earphone through a key, the main earphone needs to be paired with the secondary earphone and then paired with the external terminal, and the user needs to press the key of the earphone for a long time in the process, so that great inconvenience is brought to the user. The operation is complex, the pairing time is long, and the user experience effect is poor.

To solve the above problem, referring to fig. 1 and 2, in an embodiment of the present invention, the wireless headset includes:

a head bar 100 configured to transmit low power consumption wireless broadcast information to pair with an external terminal 400 and output an earphone switching signal;

and a master earphone 200 and a slave earphone 300 detachably and electrically connected to the headset 100, wherein when the master earphone 200 and the slave earphone 300 are respectively connected to the headset 100, the master earphone 200 and the slave earphone 300 are configured to turn on their wireless communication chip switches upon receiving the earphone switching signal.

Further, after the wireless communication chip of the master earphone 200 and the slave earphone 300 is turned on, the master earphone 200 and the slave earphone 300 send their wireless communication addresses to each other through the headband 100, so as to pair the master earphone 300 and the slave earphone 300;

further, the headset 100 is further configured to, when receiving an earphone pairing request, send a pairing check code corresponding to the earphone pairing request to the main earphone 200, so that the main earphone 200 is paired with the external terminal 400.

In this embodiment, the master earphone 200 may be a left earphone, and the slave earphone 300 may be a right earphone; alternatively, the master earphone 200 is a right earphone and the slave earphone 300 is a left earphone; or the master earphone and the slave earphone are two left earphones; or the master earphone and the slave earphone are two right earphones, which are specifically set according to the requirements of the user, and the setting is not limited here. Also, since the master and slave roles of the two earphones of the TWS earphone can be switched during use, the master earphone 200 can synchronize the related information required to establish or break the wireless connection with the device to the slave earphone 300; so that after switching from the earphone 300 to the main ear, a wireless connection with the terminal can be established according to the relevant information. The master earphone 200 and the slave earphone 300 are respectively integrated with a wireless communication chip 220, such as a bluetooth chip, and when the headset works, the wireless communication chip is connected with a terminal, such as a mobile phone, a smart watch, a tablet computer, and the like, so that when the transmission of an audio signal is realized, the terminal needs to be wirelessly connected with the earphone first. Specifically, the wireless connection is established between the master earphone 200 and the slave earphone 300, and the transmission of the audio signal is realized in an asynchronous communication mode, that is, after the terminal outputs the audio signal to the master earphone 200, the audio signal is transmitted to the right earphone through the master earphone 200.

The headpiece 100 and the two earphones can be connected in a plug-in mode, a buckle connection mode or a connection mode of the electric connector 210, and when the connection is established between the headpiece 100 and the earphones, the electric connection and the physical connection are simultaneously realized. Specifically, the connection between the headband 100 and the two earphones may be implemented through a serial port, for example, I2C, a URAT serial port, etc., after the connection is established, the headband 100 and the two earphones may transmit a data signal, for example, power information, and the headband 100 may also read data stored in the earphones, for example, a wireless communication address of the earphones, a stored address of a paired device, etc.

The head-wearing Bluetooth headset comprises a shell, a key switch, a touch switch and the like, wherein the key switch, the touch switch and the like are arranged on the shell; the electronic control board, and wireless communication chip 220, main controller 130, charging circuit, communication interface 110, the interface that charges that set up on the electronic control board. The electronic control board is usually further provided with an antenna, and is connected with the external terminal 400 through a radio frequency channel so as to be paired with the external terminal 400 which is also provided with a wireless communication chip nearby.

The wireless communication chip 220 may be a BLE (Bluetooth Low Energy) chip, and the BLE chip may utilize many intelligent means to reduce power consumption to the maximum. The BLE chip may be used to transfer data from a miniature wireless sensor (exchanging data once every half second) or other peripheral such as a remote control using fully asynchronous communication. These devices transmit very small amounts of data (typically a few bytes) and also transmit very small numbers of times (e.g., a few times per second to once per minute, or even less). When the earphone is paired with the external terminal 400, the pairing of the terminals before operation can be realized by a BLE chip because the transmitted Data is small, generally, a wireless communication address and the like, and the pairing of the terminals before operation can be realized by a BR/EDR (Basic Rate/Enhanced Data Rate) chip because the Data of the audio signal is large and the number of transmission times is large. In this embodiment, optionally set up BLE chip in the headset 100, set up BR EDR chip in master earphone 200 and slave earphone 300, adopt BLE chip in the headset 100 to realize the pairing with external terminal 400, when external terminal 400 pairs with master earphone 200, transmit corresponding data through BLE chip, can improve the transmission of data, and the consumption is lower, can transmit far away distance, is favorable to improving the wireless headset of wear-type and external terminal 400 pair efficiency.

When the wireless headset is in operation, the headset 100 may operate based on a key signal triggered by a user, or transmit BLE broadcast information to the external terminal 400 in real time in a polling manner, and operate in a scanning detection state, where the BLE broadcast information may include a device name, a device type, a device model, a battery level, a wearing state, a BLE address, and the like of the wireless headset. Accordingly, in the external terminal 400, a BLE chip and a related application are integrated, when a user needs to use the headset, the related application may be opened, and BLE broadcast information of the headset 100 is queried in a manner of searching a list, so as to pair the headset 100 and the external terminal 400. The headbar 100 also sends a headset switch signal to pair the master 200 and slave 300 headsets. For the master (slave) earphone, when the earphone switch signal is received and the bluetooth chip of the earphone is turned on to trigger the bluetooth chip to work, the master earphone sends the wireless communication address of the master earphone to the slave (master) earphone through the communication interface 110 of the headset 100, that is, when the master earphone and the slave earphone are triggered to be paired, the operation of the user is not needed, the hands of the user can be released, and the convenience of the user is provided. The slave earphone stores the wireless communication address of the master earphone and the slave earphone 300 inquires the wireless communication address of the other party in a broadcasting and scanning way, so that the verification can be quickly passed and the pairing can be completed. In this process, the headset 100 may transmit the status information of the master-slave headset 300 to the external terminal 400, so that the external terminal 400 transmits a headset pairing request to the headset 100 according to the status information, or the external terminal 400 may also set a delay device and transmit the headset pairing request to the headset 100 after a preset time. After receiving the pairing request, the headwear 100 determines whether the external terminal 400 corresponding to the pairing request is a paired terminal, if so, sends a verification code corresponding to the pairing request to the main earphone 200, the main earphone 200 stores the verification code of the external terminal 400, and when the verification code corresponding to the pairing request is consistent with the stored verification code, the main earphone 200 pairs with the external terminal 400 and establishes wireless connection.

The invention sends low-power consumption wireless broadcast information to the outside through the head strip 100 so as to match with the external terminal 400 and output an earphone switch signal, controls the wireless communication chip switches of the master earphone 200 and the slave earphone 300 to be turned on when receiving the earphone switch signal, and after receiving the earphone switch signal of the head strip 100, the wireless communication chip switches of the master earphone 200 and the slave earphone 300 are turned on and trigger the wireless communication chip to work. The wireless communication chips of the master earphone 200 and the slave earphone 300 are controlled to work through the head strip, and the process does not require a user to press keys of the earphones for a long time, so that great inconvenience is brought to the user in operation convenience.

After the wireless communication chips of the master earphone 200 and the slave earphone 300 are triggered, the master earphone 200 and the slave earphone 300 transmit their own wireless communication addresses to each other through the headset 100 to pair the master earphone 300 and the slave earphone 300, and when receiving an earphone pairing request, the slave earphone 300 transmits a pairing check code corresponding to the earphone pairing request to the master earphone 200, so that the master earphone 200 and the external terminal 400 can be paired. The master earphone 300 and the slave earphone 300 in the wireless earphone are triggered by the head strip 100 for pairing without long-time pressing of keys by a user, and the master earphone 300 and the slave earphone 300 transmit wireless communication addresses in a wired connection mode with the head strip 100 for pairing without wireless broadcasting and scanning, so that the pairing efficiency of the master earphone 300 and the master earphone 200 with the external terminal 400 can be improved.

In this embodiment, the head bar 100 further includes a memory 230, and the memory 230 may be a high-speed RAM memory 230 or a non-volatile memory 230 (e.g., a disk memory 230). The memory 230 is used for burning a communication address of the headband 100 itself, a communication address of a terminal, and various application programs and running programs for implementing the function of the headset wireless headset. The low power wireless chip 120 may be a low power bluetooth chip, and is configured to implement pairing with the external terminal 400, and obtain an instruction, a request, and the like sent by the external terminal 400. The communication interface 110 may be one of a UART serial port, I2C, SPI, and the wireless communication address of the slave earphone 300 may be given to the master earphone 200 and the wireless communication address of the master earphone 200 may be given to the slave earphone 300 by RX/TX in the communication interface 110. The communication interface 110 may also enable the main controller 130 of the headset 100 to perform data interaction with the master earphone 200 and the slave earphone 300, respectively, so that the headset 100 acquires information of the master earphone 200 and the slave earphone 300, such as power, volume, and the like, and outputs the acquired information to the external terminal 400 through the low-power wireless chip 120. The head bar 100 further includes a power interface through which a power line Vbus may supply power to the master earphone 200 and the slave earphone 300 or output an externally accessed power to the master earphone 200 and the slave earphone 300 to provide a charging path for the master earphone 200 and the slave earphone 300.

Referring to fig. 1 and 2, in an embodiment, the main controller 130 is further configured to obtain wireless communication data of the main headset 200 through the communication interface 110 when the low power wireless chip 120 is paired with an external terminal 400, and send the wireless communication data to the external terminal 400 through the low power wireless chip 120; and the number of the first and second groups,

transmitting wireless communication data of the external terminal 400 through the communication interface 110 for storage by the master earphone 200; wherein the wireless communication data comprises a check code and a wireless communication address.

The main headset 200 is further configured to establish a connection with the external terminal 400 when a check code in the stored wireless communication data of the external terminal 400 is identical to the pairing check code.

In this embodiment, when the main earphone 200 is paired with the external terminal 400 for the first time, when the external terminal 400 is paired with the headset 100, the wireless communication address of the terminal may be sent to the main earphone 200 through the headset 100, and the wireless communication address of the main earphone 200 is sent to the external terminal 400 through the headset 100, so that when an earphone pairing request sent by the external terminal 400 is received, a pairing check code corresponding to the terminal is output to the main earphone 200, when a check code in wireless communication data of the main earphone 200 is the same as the received pairing check code, it may be determined that the wireless communication address of the external terminal 400 stored by the main earphone 200 is the same as the wireless communication address of the external terminal 400 stored by the main earphone 200, and pairing is completed, the main earphone 200 and the external terminal 400 enter a wireless connection state, and the external terminal 400 may send an audio signal to the main earphone 200, thereby.

Referring to fig. 1 and 2, in an embodiment, the headwear 100 is further configured to, when receiving an earphone pairing request of a current external terminal 400 within a first preset time when the external terminal 400 is wirelessly disconnected from the main earphone 200, obtain a wireless communication address of the current external terminal 400 and determine whether the wireless communication chip 220 of the main earphone 200 is turned on in a state;

if the wireless communication chip 220 of the main headset 200 is turned on, whether the main headset 200 is paired with the current external terminal 400 is controlled according to the wireless communication address of the current external terminal 400 and the wireless communication address of the last paired external terminal 400.

It should be noted that after the wireless connection between the main headset 200 and the external terminal 400 is established, the signal may be too weak because the distance between the terminal and the main headset 200 is too large, or the user may disconnect the wireless connection actively, or the external terminal 400 may disconnect from the main headset 200 because the terminal stops using the bluetooth module due to other application control, or the like. After these factors are eliminated, the terminal may again establish a connection with the master headset 200 and send a headset pairing request to the headband 100. When the main earphone 200 is disconnected from the terminal, the headband 100 starts to calculate the time for disconnection from the terminal, and if the earphone pairing request is received within a first preset time, it is detected whether the wireless communication chip 220 of the main earphone 200 stops working. If it is detected that the wireless communication chip 220 stops working, the main earphone 200 may stop working due to the power of the main earphone 200 being too low, or the main earphone 200 failing, and the headband 100 may stop non-return. If it is detected that the wireless communication chip 220 of the main headset 200 is still in a working state, that is, in an on state, the wireless communication address of the external terminal 400 can be obtained, and the wireless communication address of the external terminal 400 is checked with the external terminal 400 paired last time, and if the wireless communication address of the external terminal 400 is the same external terminal 400, the headset pairing request is output to the main headset 200, so that the main headset 200 and the external terminal 400 are connected back.

Referring to fig. 1 and 2, in an embodiment, the headset 100 is further configured to output a headset on-off signal to the master headset 200 and the slave headset 300 when receiving a headset pairing request of the current external terminal 400 after a first preset time when the external terminal 400 is wirelessly disconnected from the master headset 200, so as to complete pairing of the master headset 300 and the slave headset 200, and control the master headset 200 to be paired with the current external terminal 400.

In this embodiment, if the time for the user to stop using the headset is not longer than the first preset time after receiving the headset pairing request, in this process, the user may replace the external terminal 400. Therefore, when it is detected that the earphone disconnection time exceeds the first preset time, the headset 100 retransmits the low power consumption wireless broadcast information, and pairs with the external terminal 400 again, and outputs an earphone switch signal to control the pairing of the master and slave earphones 300 and the master earphone 200 reestablishes a wireless connection with the external terminal 400. In the above embodiment, the first preset time may be set according to a use habit of a user, or an off-line shutdown mechanism is provided in the main earphone, so that after the first preset time, the main earphone is automatically shut down to reduce power consumption of the earphone. In an embodiment, the first predetermined time may be set to 5 to 15 minutes, and may be optionally 10 minutes.

Referring to fig. 1 and 2, in an embodiment, when the master earphone 200 and the slave earphone 300 are detached from the headset 100, respectively, the master earphone 200 and the slave earphone 300 are further configured to configure their own earphones as master devices and transmit their wireless communication addresses to different external terminals 400 to pair with the different external terminals 400.

It is understood that the master earphone 200 and the slave earphone 300 may be physically and electrically detachably connected to the headband 100. In the case where the user needs to use the master earphone 200 or the slave earphone 300 alone after detaching the master earphone 200 from the headband 100, or the master earphone 200 cannot operate normally but the slave earphone 300 needs to operate by himself or herself, etc., the master earphone 200 and the slave earphone 300 can detect the communication state of themselves with the headband 100; or a trigger switch is provided at an interface where the master earphone 200/slave earphone 300 is connected to the headband 100 to detect the connection state of the master earphone 200/slave earphone 300 to the headband 100. When the left and right earphones are physically and electrically connected to the headband 100, respectively, one of the left and right earphones is configured as the master earphone 200, and the other earphone is configured as the master earphone 300. The master earphone 200 and the external terminal 400 in the two sets establish a wireless link, receive the audio signal transmitted by the external terminal 400, and synchronously transmit the audio signal to the slave earphone 300 matched with the master earphone to realize the wireless music sharing function between the two earphones. The slave device 300 of the two is only required to wait for receiving the audio signal transmitted from the master earphone 200 after completing the pairing with the master earphone 200, and does not need to broadcast its own wireless communication address to connect with the external terminal 400.

When one of the left and right earphones is disconnected from the physical connection and the electrical connection with the head bar 100 and serves as the earphone existing in the slave earphone 300, the left and right earphones can be reconfigured to be the master earphone 200, that is, both the left and right earphones can be independently used as the master earphone 200 at the time, and when the left and right earphones serve as the master earphone 200, the left and right earphones broadcast their own wireless communication addresses to the outside to respectively pair with two different external terminals 400 and receive a pairing request, an audio signal, a data reading instruction and the like sent by the respective paired external terminals 400, thereby realizing a single earphone playing function. Compared with a head-wearing wireless earphone with left and right earphones fixed with the head strip 100, the invention can be suitable for different application requirements of users, so that the users can simultaneously realize the connection with a plurality of terminals by using a pair of earphones, thereby meeting different requirements of the users and being beneficial to improving the use efficiency of the earphones. Of course, in other embodiments, the left and right earphones may be physically and electrically connected to the headset 100 by simply detaching and storing the left and right earphones from the headset 100 without using the earphones for a certain period of time.

Referring to fig. 2 and 3, the present invention further provides a wireless headset, including:

an electrical connector 210 connected to the communication interface 110 of the headpiece 100;

a wireless communication chip 220 connected to the electrical connector 210, configured to turn on when receiving an earphone switch signal output by the headpiece 100, and receive a wireless communication address output by the headpiece 100;

a memory 230 configured to store the wireless communication address as a paired address.

It can be understood that the wireless earphones can be used in pairs or used alone, when used in pairs, the two earphones are divided into a master earphone and a slave earphone, the master earphone and the slave earphone are symmetric structures, and the slave earphone has the same structure as the master earphone. The master earphone may be a TWS earphone, and may be an earphone of left and right channels that are arranged in pairs, and a single earphone may also be used independently, and only a left channel earphone or a right channel earphone may also be an earphone that can achieve functions, in the master earphone 300, after the master earphone 300 and the slave earphone 300 are paired, the master earphone 200 may be paired and connected with a mobile terminal such as a mobile phone, and an audio signal or the like may be transmitted to the slave earphone 300 through the master earphone 200. In the main earphone, a serial communication module, a speaker, a microphone, an indicator light, a micro motor, a sensor and other components are usually further provided. In this embodiment, the memory 230 may be configured as at least three memory areas, where the three memory areas are respectively used for burning a communication address of the memory 230, a wireless communication address of an earphone paired with the memory, and a wireless communication address of the external terminal 400. The wireless communication chip 220, for example, a bluetooth chip, is provided in the wireless headset, and the bluetooth chip can be triggered based on the key signal of the user, and in this embodiment, the bluetooth chip can be controlled based on the high and low levels of the main controller 130 in the sidebar, and is turned on when receiving the high level, and is turned off when receiving the low level. After being turned on, the wireless communication address output by the sidebar 100 may be received and it may be determined whether pairing is required or in a standby state.

The wireless communication chip 220 interacts with the main controller 130 through the communication interface 110 in the headwear 100 with the communication address of the main headset to be paired. That is, before pairing, each master earphone is required to burn the communication address of the paired party into a storage area (hereinafter, flash is taken as an example) corresponding to the paired party. When the master controller 130 in the headset 100 sends a high-level headset on-off signal through the communication interface 110, the master headset 200 in the two master headsets first obtains from the flash and sends its own communication address through the communication interface 110 of the headset 100, and simultaneously, after receiving the communication address of the slave headset 300, sends a pairing request to the slave headset 300, the slave headset 300 verifies the received communication address and the paired address, pairing is completed, and the master headset 300 enters a wireless connection state.

It can be understood that, before the main earphone is paired with the external terminal 400, the headset 100 may be paired with the external terminal 400 first, that is, the headset 100 may obtain the wireless communication address of the external terminal 400 first, and at this time, the headset 100 is electrically connected to the two earphones through the communication interface 110, so that the headset 100 may send the wireless communication address of the external terminal 400 to the main earphone 200 while being paired with the external terminal 400, and thus, when receiving an earphone pairing request of the external terminal 400 sent by the main controller 130 in the headset 100, the external terminal 400 may be verified according to a check code corresponding to the pairing request, so as to implement wireless connection between the main earphone 200 and the external terminal 400.

Further, when the wireless communication address output by the headset 100 is received by the wireless communication chip 220 and is the communication address of the wireless headset, the wireless headset transmits its own wireless communication address to the wireless headset of the other party through the headset 100, so as to perform master-slave headset pairing.

In this embodiment, the master and slave earphones 300 transmit the wireless communication address through wired connection with the communication interface of the headset 100 to realize pairing, wireless broadcasting and scanning are not required, and the pairing efficiency of the master and slave earphones 300 and the master earphone 200 with the external terminal 400 can be improved.

Alternatively, when the wireless communication address outputted from the headset 100 is the communication address of the external terminal, the wireless communication chip 220 transmits its own wireless communication address to the external terminal through the headset 100, so that the wireless headset is paired with the external terminal 400.

In this embodiment, a BLE chip is integrated in the headset 100, and BLE broadcast information may be broadcast, so as to pair the headset 100 and the external terminal 400. The headbar 100 also sends a headset switch signal to pair the master 200 and slave 300 headsets. The main headset 200 transmits/receives a wireless communication address to/from the external terminal through the BLE chip of the headset 100, so that pairing with the external terminal 400 is realized, data transmission of the wireless headset can be improved, power consumption is low, a long distance can be transmitted, improvement of pairing efficiency of the wireless headset and the external terminal 400 is facilitated, and cruising ability of the wireless headset is improved.
