the triggering module 1 is used for generating a reconnection triggering instruction;
and the Bluetooth module 2 is configured to send a BLE (Bluetooth Low Energy) broadcast reconnection signal to the master earphone and/or the slave earphone after receiving the reconnection trigger instruction, so that the master earphone and the slave earphone are reconnected.
It should be noted that the trigger module 1 and the bluetooth module 2 may be disposed on the main headset, or may be disposed on another module independent from the TWS headset, such as a charging box, a mobile terminal, etc. The trigger module 1 can be a button module, a key module and the like, and in this way, a user can manually control the button module or the key module; the trigger module 1 can also be a timer, and in this way, the timer automatically outputs a reconnection trigger instruction at preset time intervals; the reconnect trigger command may be a level signal, such as a high level signal and a low level signal.
The Bluetooth module 2 is used for establishing wireless connection with Bluetooth modules in the master earphone and the slave earphone, so that signal interaction between the Bluetooth module 2 and the master earphone and the slave earphone is achieved, the master earphone and the slave earphone do not need to be specially placed in other modules to achieve reconnection of the master earphone and the slave earphone, and the operation is simple. After receiving the reconnection trigger instruction, the bluetooth module 2 sends a BLE broadcast reconnection signal to the master earphone and/or the slave earphone according to the setting condition of the bluetooth module. Specifically, when the bluetooth module 2 is arranged in a master earphone of the TWS earphone, multiplexing with the bluetooth module in the master earphone is realized, and besides realizing reconnection triggering for itself, a BLE broadcast reconnection signal is sent to the slave earphone so as to reconnect the master earphone and the slave earphone; when the bluetooth module 2 is provided on another module independent of the TWS headset, the bluetooth module 2 transmits the BLE broadcast signal to the master and slave headsets, and the master and slave headsets reconnect after receiving the BLE broadcast signal. It is thus clear that through this kind of mode, only need bluetooth module 2 to send BLE broadcast reconnection signal to master earphone and/or from the earphone, alright realize the reconnection of master earphone and follow earphone, need not master earphone and send BR reconnection signal to follow earphone, reduced the consumption of TWS earphone.

On one hand, the Bluetooth module 2 is communicated with the TWS earphone through BLE signals, so that the master ear and the slave ear can be connected again conveniently, the master earphone is not required to send BR reconnection signals, and the power consumption of the TWS earphone is reduced; on the other hand, the TWS headset does not need to be placed in a reconnection device or other devices, the reconnection device can send BLE broadcast reconnection signals to the Bluetooth module 2, the operation is simple, and the user experience is improved.
On the basis of the above-described embodiment:
as a preferred embodiment, the triggering module 1 is a button module and/or a key module and/or a timer for sending a reconnection triggering instruction at preset time intervals.
In this application, the triggering module 1 may be a button module or a key module (for example, a conventional key or a touch screen key) controlled by a user, or may be a timer for automatically outputting a reconnection triggering instruction. The reconnect trigger command may be a level signal (e.g., high or low level) or a pulse.
When the trigger module 1 is a button module or a key module, when a user presses a button or a key, the bluetooth module 2 sends a BLE broadcast reconnection signal to the master earphone and the slave earphone, and the master earphone and the slave earphone reconnect after receiving the BLE broadcast reconnection signal.
Specifically, the button module may include a button, a pull-up resistor and a power supply, where the button is equivalent to a controllable switch, one end of the button is connected to one end of the pull-up resistor and the bluetooth module 2, the other end of the button is grounded, and the other end of the pull-up resistor is connected to the power supply, so that in a normal situation, when the button is not pressed, the button is equivalent to a controllable switch being turned off, and at this time, the bluetooth module 2 receives a high level, and the bluetooth module 2 does not operate; when the button is pressed, the controllable switch is closed, the bluetooth module 2 receives a low level, the reconnection trigger instruction is received, and the bluetooth module 2 acts, namely sends a BLE broadcast reconnection signal to the master earphone and/or the slave earphone. Of course, the button module and the key module may have other structures, and the present application is not limited thereto.
When the trigger module 1 is a timer, according to the setting, the timer sends a reconnection trigger instruction every other preset time, and in practical application, the timer may send the reconnection trigger instruction every other preset time after receiving a start instruction (for example, a power signal when the timer is powered on). The preset time is not particularly limited in the present application and is determined according to actual conditions.
The embodiment can realize manual control or automatic control on reconnection of the master earphone and the slave earphone, and the control mode is flexible.
As a preferred embodiment, the trigger module 1 and the bluetooth module 2 are disposed in the charging box, and the bluetooth module 2 is specifically configured to:
sending a BLE broadcast inquiry signal to the master earphone after receiving the reconnection triggering instruction so as to inquire whether the master earphone is connected with the slave earphone or not;
if not, sending a BLE broadcast reconnection signal to the master earphone and the slave earphone so as to reconnect the master earphone and the slave earphone.
In practical application, no matter the trigger module 1 is a button module or a key module or a timer, the bluetooth module 2 disposed in the charging box can firstly send a BLE broadcast inquiry signal to inquire whether the master earphone is connected with the slave earphone or not after receiving a reconnection trigger instruction, the master earphone replies corresponding response information to the bluetooth module 2 according to the actual situation whether the master earphone is connected with the slave earphone or not, and if the bluetooth module 2 receives the information that the master earphone replies is not connected with the slave earphone, the BLE broadcast reconnection signal is sent to the master earphone and the slave earphone, so that the master earphone and the slave earphone can reconnect after receiving the BLE broadcast reconnection signal. If the Bluetooth module 2 receives the information replied by the master earphone and connected with the slave earphone, the BLE broadcast reconnection signal is not sent to the master earphone and the slave earphone.
In this embodiment, the trigger module 1 and the bluetooth module 2 are not disposed in the main headset but disposed in the charging box, so that the space occupation of the main headset is reduced. In addition, before sending the BLE broadcast reconnection signal to the master earphone and the slave earphone, the bluetooth module 2 may also inquire whether the master earphone is connected with the slave earphone, and send the BLE broadcast reconnection signal to the master earphone and the slave earphone after the master earphone replies that the master earphone is not connected with the slave earphone, so that the control mode is more reliable.
As a preferred embodiment, before sending the BLE broadcast reconnection signal to the master earphone and the slave earphone, the method further includes:
and sending a BLE broadcast distance signal to the slave earphone, judging whether a reply signal of the slave earphone is received, and if so, entering the subsequent step.
Specifically, it is considered that signal interaction is performed between the master and slave earphones and between the bluetooth module 2 and the master and slave earphones through bluetooth, and therefore, a distance between the bluetooth module 2 and the master and slave earphones is required to be within a certain range. When the distance between the bluetooth module 2 and the master and slave earphones is within a certain range (i.e. closer), the distance between the master and slave earphones is also within a certain range. In order to realize the judgment of the distance between the bluetooth module 2 and the slave earphone, in this embodiment, the bluetooth module 2 sends a BLE broadcast distance signal to the slave earphone to inquire whether the slave earphone is near the bluetooth module 2, if the distance between the slave earphone and the bluetooth module 2 is within a certain range, the slave earphone replies a corresponding response signal, after receiving the response signal from the slave earphone, the bluetooth module 2 considers that the distance between the bluetooth module 2 and the slave earphone is within a certain range, and then sends a BLE broadcast reconnection signal to the master earphone and the slave earphone, otherwise, the slave earphone cannot receive or cannot receive the BLE broadcast distance signal due to the distance, and cannot reply the corresponding response signal. The BLE broadcast distance signal and the reply signal are preset and paired, and the specific content of the BLE broadcast distance signal and the reply signal is not particularly limited in the present application and is determined according to the actual situation.
Through the mode, the Bluetooth module 2 can send BLE broadcast reconnection signals to the master earphone and the slave earphone only when the distance between the master earphone and the slave earphone is determined to be within a certain range, so that the master earphone and the slave earphone are ensured to be within the connectable distance range, and the connection reliability of the master earphone and the slave earphone is improved.
As a preferred embodiment, the trigger module 1 and the bluetooth module 2 are disposed in the master earphone, and the bluetooth module 2 is specifically configured to:
judging whether the earphone is connected with a slave earphone or not after a reconnection triggering instruction is received;
if not, sending a BLE broadcast reconnect signal to the slave earphone so that the master earphone and the slave earphone are reconnected.
In this embodiment, the trigger module 1 and the bluetooth module 2 may be further disposed in the master earphone, and in this case, the bluetooth module 2 may be multiplexed with the bluetooth module in the master earphone, and after receiving the reconnection trigger instruction sent by the trigger module 1, the bluetooth module 2 equivalently realizes reconnection triggering for itself, and may also send a BLE broadcast reconnection signal to the slave earphone, so as to realize reconnection of the master earphone and the slave earphone. Therefore, in the mode, the main earphone can realize reconnection of the main ear and the auxiliary ear without other devices except the TWS earphone, and the overall structure of the reconnection device and the TWS earphone is simplified.
In addition, the trigger module 1 can not select a key module or a button module, but preferentially selects a timer, so that the main earphone is more attractive and more comfortable to wear, and the condition of reconnection false triggering is avoided.
In practical application, the bluetooth module 2 may not be multiplexed with the bluetooth module in the master earphone, and in this case, the bluetooth module 2 may also send a BLE broadcast reconnection signal to the master earphone, which specific selection mode is not particularly limited, and is determined according to practical situations.
As a preferred embodiment, the trigger module 1 and the bluetooth module 2 are disposed in the mobile terminal, and the bluetooth module 2 is specifically configured to:
after receiving the reconnection trigger instruction, sending an inquiry signal of a preset protocol to the master earphone to inquire whether the master earphone is connected with the slave earphone or not;
if not, sending a reconnection signal of a preset protocol to the master earphone, and sending a BLE broadcast reconnection signal to the slave earphone so as to reconnect the master earphone and the slave earphone;
the preset protocol is a BR or BLE protocol.
Specifically, considering that in practical applications, the TWS headset is usually used in conjunction with a mobile terminal (the mobile terminal may be, but is not limited to, a mobile phone, a pad, etc.) (for example, a song list on the mobile terminal is played through the TWS headset), the mobile terminal and the TWS headset are connected through bluetooth, and perform signal interaction based on a BR protocol. In this embodiment, the trigger module 1 and the bluetooth module 2 may also be disposed in the mobile terminal, the mobile terminal is usually disposed with the bluetooth module 2, the bluetooth module 2 in the reconnection device may be reused with the bluetooth module 2 in the mobile terminal, and the trigger module 1 may also be reused with a key or a button in the mobile terminal, so that hardware in the mobile terminal may not be changed, and only an APP (Application, Application program) is needed to be added accordingly.
After receiving a reconnection trigger instruction, a Bluetooth module 2 in the mobile terminal sends an inquiry signal of a preset protocol to a master earphone to inquire whether the master earphone is connected with a slave earphone or not, if the information that the master earphone replies that the master earphone is not connected with the slave earphone is received, the Bluetooth module sends a reconnection signal of the preset protocol to the master earphone, and sends a BLE broadcast reconnection signal to the slave earphone, so that reconnection of the master earphone and the slave earphone is realized.
Regarding the preset protocol, if the bluetooth module 2 in the mobile terminal is being connected with the master earphone (e.g., listening to a song through the master earphone, and disconnecting from the master earphone and the slave earphone) and performing BR signal interaction (e.g., listening to a song through the earphone), the preset protocol may directly select the currently used BR protocol, and is not switched to the BLE protocol; if the bluetooth module 2 of the mobile terminal is not connected with the master earphone, the connection between the mobile terminal and the bluetooth module 2 may be established first, and a signal interaction protocol, which may be a BR protocol or a BLE protocol, may be selected, and is determined according to actual conditions. When the protocol is a BR protocol, the reconnect signal of the preset protocol may specifically be an SPP (Serial Port Profile) signal.
Therefore, through the mode, the master ear and the slave ear can be reconnected through the mobile terminal, and the control mode is flexible.
As a preferred embodiment, before sending the BLE broadcast reconnection signal to the slave headset, sending a reconnection signal of a preset protocol to the master headset further includes:
and sending a BLE broadcast searching signal, judging whether a slave earphone is searched, and if so, entering the subsequent steps.
In the above description, the master and slave earphones are connected through the bluetooth, there is a requirement for the distance between the master and slave earphones, and in order to improve the reliability of master and slave ear reconnection, in this embodiment, before sending a reconnection signal of a preset protocol to the master earphone and sending a BLE broadcast reconnection signal to the slave earphone, the bluetooth module 2 further sends a BLE broadcast searching signal, if the slave earphone is searched, it indicates that the distance between the mobile terminal and the slave earphone is short, and indirectly indicates that the distance between the master and slave earphones is short, then sends a reconnection signal of a preset protocol to the master earphone, and sends a BLE broadcast reconnection signal to the slave earphone. Therefore, through the mode, the connection of the main lug and the auxiliary lug is controlled only when the distance between the main lug and the auxiliary lug is short, and the reconnection reliability of the main lug and the auxiliary lug is improved.
