The term "module," as used herein, refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.
Referring to fig. 1, fig. 1 is a schematic view of a usage scenario of a TWS bluetooth headset provided in an embodiment of the present application, and in the embodiment of the present application, the TWS bluetooth headset includes an audio source device 100 and a TWS bluetooth headset 200, where the audio source device 100 may be an electronic device in various forms, such as a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted device, an intelligent audio device, an intelligent furniture, a wearable device, and the like.
The TWS bluetooth headset 200 includes two bluetooth headsets without physical connection, which are a master headset 201 and a slave headset 202, respectively, and wireless communication connection can be realized between the master headset 201 and the audio source device 100 and between the master headset 201 and the slave headset 202 through bluetooth, so that playing of audio data provided by the audio source device 100 can be completed through the master headset 201 and the slave headset 202, and a true wireless structure is realized.
In some embodiments, the master earphone 201 and the slave earphone 202 need to be paired with each other, the communication protocol between the master earphone 201 and the slave earphone 202 may be a standard bluetooth protocol or a non-bluetooth protocol, and the master earphone 201 and the audio source device 100 establish a standard bluetooth connection. When the audio source device 100 plays audio, the main earphone 201 obtains the bluetooth parameter that establishes bluetooth connection with the audio source device 100, and subsequently receives the data packet sent by the audio source device 100 based on the bluetooth parameter. Upon receiving the data packet transmitted from the audio source device 100, the master earphone 201 transmits the received data packet to the slave earphone 202 by using the bluetooth connection between the master earphone 201 and the slave earphone 202.
Currently, the sound source device 100 is generally accompanied by some specific prompt information during the use process, so that the user can accurately grasp the working state of the sound source device. When the TWS bluetooth headset adopts the binaural cue method, the time for outputting the cue tone from the master headset 201 and the slave headset 202 is often different due to various factors, and it is difficult to keep synchronization, so that the cue tone heard by the user is mixed.
In order to solve the above technical problem, in an embodiment of the present application, a method for synchronizing a cue message is provided, where when receiving a cue message sent by a sound source device, a master earphone predicts a play time based on a time when the cue message is received, clock offset and jitter information between the master earphone and a slave earphone, and a preset preparation time for playing the cue message from the earphone, and then carries the play time when sending the cue message to the slave earphone, and instructs the slave earphone to play the cue message at the play time, so that the master earphone and the slave earphone can play the cue message at the same time, and synchronization of output of the cue message is ensured. The following examples are given for illustrative purposes.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for synchronizing prompt messages according to an embodiment of the present application, and an execution main body of the present embodiment may be the main earphone 201 in the embodiment shown in fig. 1. As shown in fig. 2, the method includes:
s201, when the master earphone receives the prompt message sent by the sound source equipment, determining a first playing time based on a first time when the prompt message is received, clock offset and jitter information between the master earphone and the slave earphone, and a preset preparation time for playing the prompt message by the slave earphone.
In the embodiment of the present application, the master earphone and the slave earphone have their own independent clocks, and the clock offset (clock offset) between the master earphone and the slave earphone refers to the time difference between the clock of the master earphone and the clock of the slave earphone. For example, if the value of the master earphone clock is 100 and the value of the slave earphone clock is 91, then the clock offset between the master and slave earphones is 9.
The slave headset stores the clock offset, and during use, the slave headset adds the clock offset to its local clock value to determine when to listen.
When the master earphone transmits data to the slave earphone through the wireless connection at a certain moment, the slave earphone can receive the data at a certain moment, the wireless connection is established according to the time spent by the master earphone and the slave earphone, the time cannot be determined to a great extent, the time is long sometimes and short sometimes, and the time deviation is called jitter (jitter) in a Bluetooth environment. In the embodiment of the application, the time length required for the master earphone to send the prompt message to the slave earphone can be determined according to the jitter information between the master earphone and the slave earphone.
The method includes that after receiving a prompt message sent by a master earphone, a slave earphone needs to complete some initialization preparation work to play the prompt message, so that a certain time interval is usually provided between the time when the slave earphone receives the prompt message sent by the master earphone and the time when the slave earphone plays the prompt message, and the time interval is defined as preparation time for the slave earphone to play the prompt message in the embodiment of the application.
In one possible embodiment, a fixed preparation time period may be set as the preset preparation time period by measuring a plurality of times.
In a possible implementation manner of the present application, when the master earphone receives a prompt message sent by the sound source device, the clock offset of the slave earphone is read, and then a first playing time for playing the prompt message from the slave earphone is determined based on a first time when the master earphone receives the prompt message, the clock offset and jitter information, and the preset preparation time.
For example, assuming that the first time when the master earphone receives the alert information is 00:00:00.00, the clock offset between the master earphone and the slave earphone is 2 milliseconds, the time period required for the master earphone to send the alert information to the slave earphone is 1 millisecond, and the preset preparation time period for the slave earphone to play the alert information is 10 milliseconds, based on the local clock of the master earphone, the first play time when the slave earphone plays the alert information may be 00:00: 00.13. Wherein the first playing time is referenced to a clock local to the slave headset.
In another possible implementation manner of the present application, when the master earphone receives the prompt message sent by the audio source device, the master earphone may determine a second time when the slave earphone receives the prompt message based on a first time when the prompt message is received, and clock offset and jitter information between the master earphone and the slave earphone; and then determining the first playing time according to the second time and the preset preparation time.
For example, assuming that the first time when the master earphone receives the alert information is 00:00:00.00, the clock offset between the master earphone and the slave earphone is 2 milliseconds, and the time required for the master earphone to transmit the alert information to the slave earphone is 1 millisecond, when the slave earphone receives the alert information transmitted by the master earphone, the second time when the slave earphone receives the alert information transmitted by the master earphone can be 00:00:00.03, based on the clock local to the slave earphone. Meanwhile, assuming that the preset preparation time period for playing the reminder from the headphones is 10 milliseconds, the first play time at which the reminder is played from the headphones is determined to be 00:00: 00.13.
It can be understood that, after receiving the above-mentioned prompt message and the first playing time, the slave earphone plays the prompt message when the first playing time arrives based on the local clock of the slave earphone.
S202, the master earphone sends a prompt information packet to the slave earphone, the prompt information packet comprises prompt information and play time indication information, and the play time indication information is used for indicating the slave earphone to play the prompt information at a first play time.
In this embodiment of the application, after determining the first playing time, the master earphone sends the first playing time and the prompt message to the slave earphone together, and instructs the slave earphone to play the prompt message at the first playing time.
In a feasible implementation manner of the present application, in order to ensure the real-time performance of receiving the prompt information by the master earphone and the slave earphone, the time for information interaction between the master earphone and the slave earphone may be reduced by adjusting a Sniff sub-rating (SSR), so as to improve the "real-time performance" of the prompt information.
S203, the master earphone determines a second playing time based on the first playing time and the clock offset between the master earphone and the slave earphone, and plays the prompt message at the second playing time.
In this embodiment of the application, after determining the first play time, the master earphone determines a second play time at which the master earphone plays the prompt message based on the first play time and a clock offset between the master earphone and the slave earphone.
For example, assuming that the first time when the master earphone receives the reminder message is 00:00:00.00 and the clock offset is 2 milliseconds, the second playing time when the master earphone plays the reminder message may be 00:00: 00.11. Wherein the second playing moment is referenced to a local clock of the master earphone.
It can be understood that, after the master earphone determines the second playing time, the prompt message is played when the second playing time arrives based on a local clock of the master earphone. Due to the clock offset between the master and slave earphones, the first playing time "00: 00: 00.13" determined based on the slave earphone clock and the second playing time "00: 00: 00.11" determined based on the master earphone clock are actually the same point in time with respect to the user and, at the same time, with respect to the local clock of the audio source device.
According to the method for synchronizing the prompt messages, when the master earphone receives the prompt messages sent by the sound source equipment, the time for playing the prompt messages from the slave earphone is predicted based on the first time for receiving the prompt messages, clock offset and jitter information between the master earphone and the slave earphone and the preset preparation time for playing the prompt messages from the earphone, and then the time and the prompt messages are sent to the slave earphone at the same time, and the slave earphone is instructed to play the prompt messages at the time; meanwhile, the master earphone plays the prompt information at the same time point based on the time and the clock offset between the master earphone and the slave earphone, so that the output prompt information between the master earphone and the slave earphone can be kept synchronous.
Based on the content described in the foregoing embodiment, referring to fig. 3, fig. 3 is another schematic flow chart of the method for synchronizing prompt information provided in the embodiment of the present application. In some embodiments, the method comprises:

In some embodiments, the prompt message includes any one of the following prompt messages generated by the audio source device: starting up prompt, closing down prompt, electric quantity prompt, volume adjustment prompt, short message prompt, unlocking prompt and screen locking prompt.

And S303, the master earphone receives feedback information sent by the slave earphone, wherein the feedback information comprises a third playing time for playing the prompt information, which is determined based on a local clock of the slave earphone after the slave earphone receives the prompt information packet.
In the embodiment of the application, after receiving the prompt message sent by the master earphone, the slave earphone determines the time when the slave earphone actually receives the prompt message based on a local clock of the slave earphone, predicts a third playing time at which the slave earphone can play the prompt message most quickly according to the time and a preset preparation time for playing the prompt message by the slave earphone, and feeds the third playing time back to the master earphone. Wherein the third playing time is referenced to a clock local to the slave headset.
S304, determining whether the first playing time is effective. If not, continuing to execute the steps S305-S307; if yes, go to step S308.
In some embodiments of the present application, it can be understood that, when the third playing time is later than the first playing time, that is, it indicates that the slave earphone cannot play the prompt message at the first playing time specified by the master device, at this time, it may be determined that the first playing time is invalid; when the third playing time is not later than the first playing time, that is, the slave earphone can play the prompt message at the first playing time specified by the master equipment, and at this time, it can be determined that the first playing time is valid.
S305, the master earphone adjusts the playing time indication information according to the third playing time.
And S306, the master earphone sends the adjusted playing time indication information to the slave earphone, wherein the adjusted playing time indication information is used for indicating the slave earphone to play the prompt information at the playing time indicated by the adjusted playing time indication information.
In a possible implementation manner of the present application, when the master earphone determines that the slave earphone cannot play the prompt message at the first play time, the master earphone adjusts the play time indication message, and sends the adjusted play time indication message to the slave earphone to instruct the slave earphone to play the prompt message at a third play time.
In another possible implementation manner of the present application, when the master earphone determines that the slave earphone cannot play the prompt message at the first play time, the first play time is adjusted to be the third play time, and after generating the adjusted play time indication information based on the adjusted first play time, the adjusted play time indication information is sent to the slave earphone to indicate the slave earphone to play the prompt message at the third play time.
In some embodiments of the present application, when the master earphone determines that the slave earphone cannot play the prompt message at the first play time, the master earphone may adjust the first play time to a time after the third play time, generate the adjusted play time indication information based on the adjusted first play time, and transmit the adjusted play time indication information to the slave earphone to instruct the slave earphone to play the prompt message at a time after the third play time.
And S307, the master earphone adjusts the second playing time based on the third playing time and the clock offset between the master earphone and the slave earphone, and plays the prompt message at the adjusted second playing time.
In this embodiment of the application, after the time when the slave earphone plays the prompt message is adjusted, the master earphone needs to adjust the play time of the master earphone in time according to the adjusted play time of the slave earphone, so that the master earphone and the slave earphone can play the prompt message at the same time point.
S308, the master earphone determines a second playing time based on the first playing time and the clock offset between the master earphone and the slave earphone, and plays the prompt message at the second playing time.
In this embodiment of the application, when it is determined that the slave earphone can play the prompt message at the first play time specified by the master device, the master earphone may determine a second play time based on the first play time and a clock offset between the master earphone and the slave earphone, and play the prompt message at the second play time, thereby ensuring that the master earphone and the slave earphone can play the prompt message at the same time point.
