Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
Fig. 1 schematically shows a master-slave switching method for a TWS headset according to an embodiment of the present invention, where the master-slave switching method is suitable for a binaural use mode, that is, when both the master headset and the slave headset are worn on ears of a user, the master headset is a headset currently connected to a terminal, and the slave headset is a headset not currently connected to the terminal, and the master headset and the slave headset need to be placed in a charging box for charging due to insufficient power of the master headset.
As shown in fig. 1, the master-slave switching method of the TWS headset includes:
s100, the main earphone receives an in-place instruction.
Wherein, the in-place instruction is an instruction generated when the main earphone is detected to be placed in the charging box.
In the present embodiment, in order to simplify the structure of the TWS headset, the execution subject of the operation of detecting that the primary headset is placed in the charging box is the charging box in such a manner that when the charging box detects that the primary headset is placed in the charging box, the charging box generates an in-position instruction and transmits the in-position instruction to the primary headset. When the charging box detects that both the master and slave earphones are placed into the charging box, the charging box does not generate an in-place instruction. That is, the charging box generates an in-place command and sends the in-place command to the primary earpiece only when the charging box detects that the primary earpiece is placed in the charging box.
The box that charges can realize through various sensors whether main earphone places the detection in the box that charges, the kind and the setting position of sensor, and the producer can set for according to actual conditions, for example when the sensor is pressure sensor, this pressure sensor can set up the side that main earphone placed the position in the box that charges. Of course, the sensor may also be a light sensor or the like.
In this embodiment, in order to improve and detect the precision, can be equipped with the MCU module in the box that charges, the MCU module is used for detecting the switching of magnetism switch of inhaling, and when the MCU module detects the magnetism switch that inhales that corresponds the setting with main earphone and is in the closed condition, the box that charges sends instruction in place to main earphone.
In order to enable the charging box and the main earphone to smoothly realize data interaction, a power supply contact is arranged on the charging box, a charging contact is arranged on the TWS earphone, and charging and communication interaction between the charging box and the TWS earphone can be realized through the power supply contact and the charging contact which are connected mutually. Therefore, the two-wire interaction mode is adopted between the charging box and the TWS earphone, namely, the charging and the communication interaction between the charging box and the TWS earphone can be realized through the mutually connected power supply contact and charging contact, so that the number of PIN needles can be reduced, the production cost is effectively reduced, and meanwhile, the structures of the TWS earphone and the charging box can be simplified.
The charging box can send an in-place instruction to the main earphone through a customized high-low level coding format. Therefore, the charging box can realize the coded transmission of the on-position instruction by controlling the charging voltage, and the main earphone can acquire the on-position instruction transmitted by the charging box by detecting the change of the charging voltage.
S200, when the master earphone receives the in-place instruction, the master earphone sends the connection information of the master earphone and the terminal to the slave earphone, so that the slave earphone initiates a connection request to the terminal according to the connection information and establishes connection, and master-slave switching of the TWS earphone is completed.
When the in-place instruction is received by the main earphone, the main earphone is indicated to be placed into the charging box by the user, and the main earphone is indicated to stop working, namely to be disconnected from the terminal. At this time, in order to ensure that the slave earphone can continue to work, the master earphone sends the connection information between the master earphone and the terminal to the slave earphone (for example, the master earphone sends the connection information between the master earphone and the terminal to the slave earphone through the established bluetooth link), the slave earphone initiates a connection request to the terminal according to the connection information and establishes connection, that is, data interaction with the terminal can be realized, so that work can continue, normal use of a user is ensured, at this time, master-slave switching of the TWS earphone is completed, that is, the slave earphone is switched to the current master earphone.
In this embodiment, the content of the connection information is not limited, and may include, for example, a MAC address of the terminal, as long as the connection can be established from the headset to the terminal through the connection information, thereby achieving data interaction.
In the present embodiment, the timing of transmitting the connection information to the slave earphone by the master earphone is not limited, and the connection information may be transmitted to the slave earphone immediately when the master earphone receives the presence instruction, or may be transmitted to the slave earphone when the master earphone disconnects from the terminal, for example. As long as the slave earphone can receive the current connection information with the terminal sent by the master earphone.
Since only one earphone can be connected with the terminal at the same time, the slave earphone wants to initiate a connection request to the terminal through the connection information and establish a connection, and the master earphone must be disconnected from the terminal. The present embodiment does not limit the time when the master earphone is disconnected from the terminal, and for example, the master earphone may be disconnected from the terminal when receiving the in-place instruction; or the connection with the terminal is disconnected after the master earphone sends the connection information of the master earphone and the terminal to the slave earphone; it is of course also possible that the master earphone is disconnected from the terminal when the slave earphone is ready to establish a connection with the terminal. The shorter the time interval between the disconnection of the master earphone and the terminal and the establishment of the connection of the slave earphone with the terminal according to the connection information, the better the user experience. Therefore, preferably, after the master earphone sends the connection information to the slave earphone, before the slave earphone initiates a connection request to the terminal according to the connection information and establishes a connection, the method further includes: the main earphone is disconnected with the terminal.
In order to ensure that the connection information is successfully received from the headset, the present embodiment may further establish a first feedback mechanism by which it is ensured that the connection information is successfully received from the headset. The present embodiment does not limit the method of executing the specific first feedback mechanism. For example, the successful reception feedback information may be sent to the master earphone when the connection information is successfully received from the earphone, and the master earphone determines that the connection information is successfully received from the earphone when the connection information is received from the earphone. Or the slave earphone does not receive the connection information within the designated time, the request for obtaining the connection information again is sent to the master earphone until the slave earphone successfully receives the connection information.
To further enhance the user experience, the MAC address of the master earpiece is the same as the MAC address of the slave earpiece. The main earphone and the slave earphone share the same MAC address, so that the terminal and the TWS earphone always transmit audio signals through the same MAC address, the problem of secondary Bluetooth pairing caused by different MAC addresses of the main earphone and the slave earphone is solved in the switching process of the main earphone and the slave earphone, the communication and audio link established between the TWS earphone and the terminal only needs to be reconnected, and the link of the traditional TWS earphone needs to be completely reestablished in the switching process of the main earphone and the slave earphone. By adopting the switching method of the master earphone and the slave earphone provided by the invention, the switching of the master earphone and the slave earphone is natural and smooth, almost has no time delay, and can not cause the blocking of sound.
In order to further improve the user experience, the master-slave switching method provided by this embodiment may further include: and the master earphone sends the current service information to the slave earphone, and the slave earphone recovers the service work according to the current service information. The current service information refers to the working data of the current TWS headset, for example, whether music playing or conversation is currently performed or a novel is currently being played can be determined from the headset according to the current service information, and the current working progress, for example, if music is currently being played, a specific position of which song is played. Therefore, after the slave earphone is connected with the terminal again, the slave earphone can continue to execute the previous task according to the current service information, so that the user can not feel the master-slave switching process of the two earphones, the user does not need to execute the playing action again, and the user experience is greatly improved.
In this embodiment, the time when the master earphone sends the current service information to the slave earphone is not limited, and for example, the master earphone may send the current service information to the slave earphone after receiving the in-place instruction; or the master earphone sends the connection information of the master earphone and the terminal to the slave earphone and simultaneously sends the current service information. As long as the current traffic information is sent to the slave headset before the master headset is disconnected from the terminal.
In order to ensure that the slave earphone can successfully receive the current service information, the embodiment may further establish a second feedback mechanism, and the slave earphone is ensured to successfully receive the current service information through the second feedback mechanism. The embodiment does not limit the specific execution method of the second feedback mechanism, for example, feedback information of successful reception may be sent to the master earphone when the current service information is received from the earphone, and when the master earphone receives the information, it is determined that the current service information is successfully received from the earphone. Or the slave earphone does not receive the current service information within the appointed time, a request for obtaining the current service information again is sent to the master earphone until the slave earphone successfully receives the current service information.
In summary, in the method for switching between master and slave of the TWS headset according to the embodiment, by detecting the in-place state of the master headset, that is, whether the master headset is placed in the charging box, it is determined whether to switch between the master headset and the slave headset, so that a problem that the slave headset worn on the ear of a person cannot continue to work because the master headset is disconnected from the terminal when the master headset is placed in the charging box in the prior art is solved.
Fig. 2 schematically shows a master-slave switching method of a TWS headset according to another embodiment of the present invention, which is suitable for a single-ear use mode, that is, the master headset and the slave headset are both placed in a charging box, when a box cover of the charging box is opened, one of the headsets is taken out to be worn on a human ear for use, and the taken-out headset is a slave headset, where the master headset is a headset currently connected to a terminal, and the slave headset is a headset currently not connected to the terminal.
As shown in fig. 2, the master-slave switching method of the TWS headset includes:
and S1, receiving the off-position instruction from the earphone.
Wherein the off-position instruction is an instruction generated when the earphone is detected to leave the charging box.
In the present embodiment, in order to reduce the switching time between the master and slave earphones, the execution unit that generates the unseating command is the slave earphone, and when the slave earphone detects that the slave earphone is separated from the charging box, the slave earphone generates the unseating command. The detection of whether the slave earphone leaves the charging box can be realized according to the connection state of the slave earphone and the charging circuit of the charging box. When the slave earphone detects that a charging circuit between the slave earphone and the charging box is in a disconnected state, an off-position instruction is generated.
And S2, when the slave earphone receives the off-position instruction, the slave earphone sends a connection request to the terminal and establishes connection, and the charging box sends a switching instruction to the master earphone so that the master earphone is disconnected from the terminal, thereby completing master-slave switching of the TWS earphone.
When the slave earphone receives the off-position instruction, the slave earphone indicates that the slave earphone is taken out of the charging box by the user, and the slave earphone indicates that the user wants to establish connection with the terminal through the slave earphone. At this moment, in order to ensure that the slave earphone can work smoothly, the slave earphone initiates a connection request to the terminal and establishes connection, and the slave earphone is switched to the current master earphone, so that data interaction between the slave earphone and the terminal is realized, and normal use of a user is ensured.
Since only one earphone can be connected with the terminal at the same time, the slave earphone wants to initiate a connection request to the terminal and establish a connection, and the master earphone must be disconnected from the terminal. Thus, after the charging box detects that the slave earphone leaves the charging box and before the slave earphone initiates a connection request to the terminal and establishes a connection, the charging box sends a switching instruction to the master earphone to disconnect the master earphone from the terminal.
In this embodiment, in order to improve the detection precision, the charging box can be provided with an MCU module therein, the MCU module is used to detect the on/off of the magnetic switch, and when the MCU module detects that the magnetic switch corresponding to the slave earphone is in an off state, the charging box sends a switching command to the master earphone, so that the master earphone is disconnected from the terminal.
In order to enable the charging box and the main earphone to smoothly realize data interaction, a power supply contact is arranged on the charging box, a charging contact is arranged on the TWS earphone, and charging and communication interaction between the charging box and the TWS earphone can be realized through the power supply contact and the charging contact which are connected mutually. Therefore, the two-wire interaction mode is adopted between the charging box and the TWS earphone, namely, the charging and the communication interaction between the charging box and the TWS earphone can be realized through the mutually connected power supply contact and charging contact, so that the number of PIN needles can be reduced, the production cost is effectively reduced, and meanwhile, the structures of the TWS earphone and the charging box can be simplified.
The charging box can send a switching instruction to the main earphone through a customized high-low level coding format. Therefore, the charging box can realize the coded transmission of the switching instruction by controlling the charging voltage, and the main earphone can acquire the switching instruction transmitted by the charging box by detecting the change of the charging voltage.
To further enhance the user experience, the MAC address of the master earpiece is the same as the MAC address of the slave earpiece. Because the master earphone and the slave earphone share the same MAC address, the terminal and the TWS earphone always transmit audio signals through the same MAC address, the problem of secondary Bluetooth pairing caused by different MAC addresses of the master earphone and the slave earphone can be avoided in the switching process of the master earphone and the slave earphone, and a link of the traditional TWS earphone needs to be completely reestablished in the switching process of the master earphone and the slave earphone. By adopting the switching method of the master earphone and the slave earphone provided by the invention, the switching of the master earphone and the slave earphone is natural and smooth and almost has no time delay.
In summary, the master-slave switching method for the TWS headset according to the embodiment determines whether to switch the master headset and the slave headset by detecting the off-position state of the slave headset, that is, whether the slave headset is taken out from the charging box, so as to solve the problem that the slave headset cannot be normally used if the slave headset is taken out from the charging box in the single-ear mode in the prior art.
