The communication time slot allocation method provided in the embodiment of the present application may be applied to an application environment shown in fig. 1, where the application environment includes a terminal device 101 and an earphone set 102, and the earphone set 102 includes a master earphone 1021 and a slave earphone 1022. The terminal 101 performs data transmission with the headset 102 through interaction with the master headset 1021, and the slave headset 1022 performs data transmission through interaction with the master headset 1021, when the terminal device 101 needs to send data to the headset 102, the terminal device 101 sends the data to the master headset 1021, and then the master headset 1021 sends corresponding data to the slave headset 1022 according to the need. Similarly, when the slave earphone 1022 needs to transmit data to the terminal apparatus 101, the data needs to be transmitted to the master earphone 1021, and the master earphone 1021 is transmitted to the terminal apparatus 101. The terminal device 101 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The earphone set 102 is a true wireless stereo earphone.

The communication time slot allocation method provided by the embodiment of the application is applied to a data transmission process when the earphone set 102 performs binaural recording, after the earphone set 102 and the terminal equipment 101 are successfully connected in a communication manner, a recording action is performed in response to a recording starting instruction sent by the terminal equipment 101, the master earphone 1021 and the slave earphone 1022 respectively acquire audio data through microphones and respectively encode the acquired audio data, the slave earphone 1022 stores a slave recording data packet generated after encoding into a buffer zone, and the slave recording data packet is sent to the master earphone 1021 through a communication connection established with the master earphone 1021; the master earphone 1021 encodes the audio data collected by the microphone thereof to generate a master recording data packet, and stores the master recording data packet in the local master buffer area, and the master earphone 1021 receives a slave recording data packet sent by the slave earphone 1022 and stores the slave recording data packet in the slave buffer area. When the uplink transmission is started, the master earphone 1021 acquires a master recording data packet in a local master buffer, sequentially acquires a slave recording data packet and the master recording data packet in a slave buffer for synchronous comparison, the master recording data packet and the slave recording data packet which are synchronous in comparison are combined into a binaural data packet, the binaural data packet is transmitted to the terminal equipment 101 through communication connection with the terminal equipment 101, the data corresponding to the successfully transmitted binaural data packet is cleared from the buffer by the master earphone 1021, the corresponding master recording data packet is cleared from the master buffer, and the corresponding slave recording data packet is cleared from the slave buffer.

In one embodiment, as shown in fig. 2, a communication time slot allocation method is provided, and the method is applied to the master earphone in fig. 1 for illustration, and includes the following steps:

step 201, identifying the number of buffered master record data packets and the number of slave record data packets.

The main recording data packet is an audio data packet which is recorded and generated by the main earphone; the slave recording data packet is an audio data packet recorded by the slave earphone and transmitted to the master earphone.

Step 202, determining a time slot ratio of the first time slot to the second time slot according to the number of the main recording data packets and the number of the slave recording data packets.

The method comprises the steps that a first time slot is a communication time slot allocated to terminal equipment, a master earphone sends a double-ear data packet to the terminal equipment in the first time slot, and the double-ear data packet is generated by the master earphone based on a synchronous master recording data packet and a slave recording data packet; the second time slot is a communication time slot allocated to the slave earphone, and the master earphone receives the slave recording data packet sent by the slave earphone in the second time slot. The communication time slot refers to time slices of time division multiplexing, the communication device divides a communication period into a plurality of time slices, and the time slices are distributed to different devices for communication interaction, so that the interaction with the different devices is avoided, and the time division multiplexing communication is realized. In the embodiment of the present application, the sum of the first time slot and the second time slot is constant, and when the first time slot increases, the second time slot decreases; conversely, as the first time slot decreases, the second time slot increases. When the time slot ratio is increased, namely the first time slot is increased, more communication bandwidth is allocated to the terminal equipment at the moment; when the slot ratio is reduced, that is, the second slot is increased, the communication bandwidth allocated to the terminal device is reduced, the communication bandwidth allocated to the slave earphone is increased, and the increase of the communication bandwidth can improve the data transmission efficiency.

When the communication signal strength between the terminal equipment and the main earphone is poor, if the original communication bandwidth is maintained, the data transmission efficiency is reduced, even the data cannot be successfully transmitted, at the moment, the time slot ratio can be increased, and therefore the data transmission stability between the main earphone and the terminal equipment is ensured. If the communication signal strength between the master earphone and the slave earphone is poor, if the original communication bandwidth is maintained, the slave earphone may not transmit the slave recording data packet, the master earphone may not generate the binaural data packet and transmit the binaural data packet to the terminal device, and at this time, the duty ratio of the second time slot may be increased, so as to ensure the stability of recording data transmission.

According to the number of the main recording data packets and the auxiliary recording data packets cached by the main earphone, the communication signal intensity between the main earphone and the terminal equipment and between the main earphone and the auxiliary earphone can be judged. Specifically, when the communication signal strength between the master earphone and the terminal device is poor, uplink data transmission cannot be normally realized, and at this time, the slave earphone continuously transmits slave recording data packets according to the originally allocated second time slot, which can lead to continuous increase of the number of data packets buffered by the master earphone, that is, continuous accumulation of the data packets to be transmitted to the terminal device, and at this time, the first time slot can be increased, that is, the time slot ratio is improved. When the communication signal intensity between the master earphone and the slave earphone is poor, the success rate of the slave earphone for transmitting the slave recording data packet is reduced, but at the moment, the terminal equipment still receives the double-ear data packet according to the allocated first time slot, so that the slave recording data packet cached by the master earphone is less or even zero, and the data transmission between the master earphone and the slave earphone can be ensured by increasing the second time slot, namely reducing the time slot ratio.

Step 203, sending a time slot adjustment notice to the terminal device and the slave earphone according to the time slot ratio.

Wherein the slot adjustment notification is used to notify the terminal device and adjust the slot allocation from the headset. The terminal equipment and the slave earphone notify corresponding adjustment time slot allocation according to the monitoring time slot adjustment, thereby ensuring that binaural recording data of the earphone set can be stably transmitted.

According to the communication time slot allocation method, the communication signal intensity change between the master earphone and the terminal equipment is judged by identifying the number of the master recording data packets and the number of the slave recording data packets cached by the master earphone, the time slot ratio of the first time slot allocated to the terminal equipment to the second time slot allocated to the slave earphone is determined according to the number of the master recording data packets and the number of the slave recording data packets, and the time slot adjustment notification is sent according to the time slot ratio to inform the terminal equipment and the slave earphone to adjust the time slot allocation, so that the communication bandwidth of interaction between the master earphone and the slave earphone and the terminal equipment respectively is dynamically adjusted, and the stability of data transmission is improved.

In one embodiment, as shown in fig. 3, the determining the time slot ratio of the first time slot to the second time slot according to the number of the main recording data packets and the number of the slave recording data packets includes:

Step 301, it is determined whether the number of primary recording data packets is greater than a first threshold and whether the number of secondary recording data packets is greater than a second threshold.

The first threshold is used for measuring whether the number of the main recording data packets exceeds the due buffering quantity under the normal signal strength, and the second threshold is used for measuring whether the number of the auxiliary recording data packets exceeds the applied buffering quantity under the normal signal strength. The first threshold value and the second threshold value may be equal or different.

In step 302, if the number of the master recording data packets is greater than the first threshold and the number of the slave recording data packets is greater than the second threshold, the timeslot ratio is determined as a first preset timeslot ratio.

When the number of the master recording data packets is greater than the first threshold and the number of the slave recording data packets is greater than the second threshold, that is, both the master recording data packets and the slave recording data packets exceed the normal buffer when the communication signals between the master earphone and the terminal equipment and between the master earphone and the slave earphone are normal respectively, the communication signal strength between the master earphone and the terminal equipment may be poor at this time, for example, the bluetooth signal between the master audio equipment and the terminal equipment is interfered or the communication signal is weak because the distance between the master earphone and the terminal equipment is far, so that the master earphone cannot normally upload the binaural data packets to release the buffer, the ratio of the first time slot needs to be improved at this time, and the time slot ratio should be determined as a first preset time slot ratio.

In step 303, if the number of the master recording data packets is not greater than the first threshold, or the number of the slave recording data packets is not greater than the second threshold, the timeslot ratio is determined as the second preset timeslot ratio or the third preset timeslot ratio.

When the number of the main recording data packets is not greater than the first threshold value or the number of the auxiliary recording data packets is not greater than the second threshold value, the communication signal intensity between the main earphone and the terminal equipment is normal, the duty ratio of the first time slot can be properly reduced, but the time slot ratio is finally determined to be the second preset time slot ratio or the third preset time slot ratio according to the communication signal intensity between the main earphone and the auxiliary earphone. Wherein the first preset time slot ratio is greater than a third preset time slot ratio, which is greater than the second preset time slot ratio.

It should be noted that, there is no sequence between the step 302 and the step 303, which are the steps to be executed under different conditions.

In one embodiment, if the number of the master recording data packets is not greater than the first threshold value, or the number of the slave recording data packets is not greater than the second threshold value, comparing whether the difference between the number of the master recording data packets and the number of the slave recording data packets is greater than the third threshold value; if the difference between the number of the master recording data packets and the number of the slave recording data packets is larger than a third threshold value, the time slot ratio is determined as a second preset time slot ratio.

The third threshold is used for measuring whether the difference between the number of the main recording data packets and the number of the auxiliary recording data packets exceeds the difference between the communication signals of the main earphone and the auxiliary earphone when the communication signals are normal.

When the difference between the number of the master recording data packets and the number of the slave recording data packets exceeds a normal value, the fact that more master recording data packets cannot generate binaural recording data packets for transmission and release is indicated, namely the success rate of transmitting the slave recording data packets from the slave earphone is reduced, so that fewer slave recording data packets are buffered by the master earphone, namely the communication signal strength between the master earphone and the slave earphone is poor. At this time, the duty ratio of the second time slot can be increased, and a smaller second preset time slot ratio is selected, so that the communication bandwidth of the master earphone and the slave earphone is increased, and the success rate of the slave earphone for transmitting the slave recording data packet is ensured.

In one embodiment, if the number of the master recording data packets is not greater than the first threshold value, or the number of the slave recording data packets is not greater than the second threshold value, comparing whether the difference between the number of the master recording data packets and the number of the slave recording data packets is greater than the third threshold value; if the difference between the number of the master recording data packets and the number of the slave recording data packets is smaller than or equal to a third threshold value, the time slot ratio is determined as a third preset time slot ratio.

When the difference between the number of the master recording data packets and the number of the slave recording data packets does not exceed the difference between the communication signals of the master earphone and the slave earphone when the communication signals of the master earphone and the slave earphone are normal, the ratio of the number of the currently cached master recording data packets to the number of the slave recording data packets is normal, and the binaural data packets can be normally sent, namely, the communication signal intensity between the master earphone and the slave earphone is normal. And the number of the main recording data packets is not more than a first threshold value and the number of the auxiliary recording data packets is not more than a second threshold value, namely the communication signal strength between the main earphone and the terminal equipment is normal. In this case, the timeslot ratio corresponding to the normal signal strength may be selected, and since the data amount of the single binaural data packet is obviously larger than the data amount of the single slave recording data packet, in order to ensure the data transmission stability, a certain communication bandwidth needs to be allocated to the terminal device appropriately, so that a third preset timeslot ratio larger than the second preset timeslot ratio may be selected.

Illustratively, the first preset slot ratio may be 4:1, the second preset slot ratio may be 1:1, the third preset slot ratio may be 2:1.

as shown in fig. 4, the determining the time slot ratio of the first time slot to the second time slot according to the number of the master recording data packets and the number of the slave recording data packets includes:

Step 401, if the number of the master recording data packets is not greater than the first threshold value, or the number of the slave recording data packets is not greater than the second threshold value, comparing whether the difference between the number of the master recording data packets and the number of the slave recording data packets is greater than the third threshold value;

step 402, if the difference between the number of the master recording data packets and the number of the slave recording data packets is greater than a third threshold, determining the timeslot ratio as a second preset timeslot ratio;

step 403, if the difference between the number of the master recording data packets and the number of the slave recording data packets is less than or equal to the third threshold, determining the timeslot ratio as a third preset timeslot ratio.

It should be noted that, there is no sequence between step 402 and step 403, and steps of correspondingly determining different slot ratios under two conditions are respectively performed.

In one embodiment, the third predetermined time slot ratio is a default time slot ratio, i.e., the third predetermined time slot ratio is preferentially selected after the recording is started.

In order to avoid frequent adjustment of the timeslot ratio due to the change of the number of the master recording data packets and the number of the slave recording data packets buffered by the master earphone, referring to fig. 5, in one embodiment, the determining the timeslot ratio as the first preset timeslot ratio includes the following steps:

In step 501, a first duration is obtained in which the number of primary recording data packets is greater than a first threshold and the number of secondary recording data packets is greater than a second threshold.

Wherein the first duration is a maintenance time of a state in which the number of main recording data packets is greater than the first threshold value and the number of sub recording data packets is greater than the second threshold value, it is understood that once the number of main recording data packets is not greater than the first threshold value or the number of sub recording data packets is not greater than the second threshold value, the calculation of the first duration is stopped until the state is re-entered again.

Step 502, determining whether the first duration reaches a first preset duration.

In step 503, if the first duration reaches the first preset duration, determining the timeslot ratio as the first preset timeslot ratio is performed.

In step 504, if the first duration does not reach the first preset duration, the timeslot ratio is temporarily not adjusted.

Judging whether the time slot ratio needs to be adjusted or not through the first preset time length, and when the first duration reaches the first preset time length, namely the communication signal strength between the terminal equipment and the main earphone cannot be recovered to be normal temporarily, maintaining the stability of the transmission of the recording data through intervening the time slot ratio.

Similarly, in one embodiment, the determining the slot ratio as the second preset slot ratio includes the following steps:

step 505, obtaining a second duration in which a difference between the number of master recording data packets and the number of slave recording data packets is greater than a third threshold.

Wherein the second duration is a maintenance time of a state in which a difference between the number of the master recording data packets and the number of the slave recording data packets is greater than a third threshold, it is understood that once the difference between the number of the master recording data packets and the number of the slave recording data packets is not greater than the third threshold, the calculation of the second duration is stopped until the second duration is recalculated when the state is re-entered.

Step 506, determining whether the second duration reaches a second preset duration.

If the second duration reaches the second preset duration, step 507, determining the timeslot ratio as the second preset timeslot ratio is performed.

In step 508, if the second duration does not reach the second preset duration, the timeslot ratio is not adjusted.

Judging whether the time slot ratio needs to be adjusted or not through the second preset time length, and when the second duration time reaches the second preset time length, namely the communication signal strength between the slave earphone and the master earphone cannot be recovered to be normal temporarily, maintaining the stability of the transmission of the recording data through intervening the time slot ratio.

In one embodiment, on the other hand, the determining the slot ratio as the third preset slot ratio includes the following steps:

step 509, obtaining a third duration in which a difference between the number of master recording packets and the number of slave recording packets is less than or equal to a third threshold.

Wherein the third duration is a maintenance time of a state in which a difference between the number of the master recording data packets and the number of the slave recording data packets is less than or equal to a third threshold, it is understood that once the difference between the number of the master recording data packets and the number of the slave recording data packets is greater than the third threshold, the calculation of the third duration is stopped until the third duration is recalculated when the state is re-entered.

In step 511, it is determined whether the third duration reaches a third preset duration.

If the third duration reaches the third preset duration, step 512 is executed to determine the slot ratio as the third preset slot ratio.

In step 513, if the third duration does not reach the third preset duration, the timeslot ratio is temporarily not adjusted.

Judging whether the time slot ratio needs to be adjusted or not through the third preset time length, and when the third duration time reaches the third preset time length, namely the communication signal strength between the master earphone and the slave earphone as well as between the master earphone and the terminal equipment is normal, selecting the third time slot ratio to maintain normal recording data transmission.

In one embodiment, as shown in fig. 6, a communication time slot allocation method is provided, and the method is applied to the master earphone in fig. 1 for illustration, and includes the following steps:

step 601, determining a transmitted number of binaural data packets to be transmitted to a terminal device within a preset time and a received number of slave recording data packets to be received from a headset.

Wherein the binaural data packet is generated based on the synchronized master recording data packet and slave recording data packet; the main recording data packet is an audio data packet which is recorded and generated by a main earphone; the slave recording data packet is an audio data packet recorded by the slave earphone and transmitted to the master earphone. The preset time is a period of time ending at the current time, i.e. the transmitted number of binaural data packets and the received number of slave recording data packets from before the preset time to the current time are determined. The number of transmitted binaural data packets may be determined by collecting the amount of transmitted during a preset time or determined from the transmission record, and the number of received binaural data packets may be determined from the recorded audio data packets by collecting the amount of received during a preset time or determined from the received record.

By way of example, the preset time may be 20ms, i.e. the transmitted data of the binaural data packets and the received number of slave recording data packets within 20ms from the current time instant onwards are determined. The preset time can be set as required.

Step 602, determining a slot ratio of the first slot to the second slot according to the transmitted number and the received number.

The definition of the first time slot and the second time slot is the same as that of the foregoing embodiment, and will not be described herein.

Whether the success rate of uplink data transmission is reduced due to the change of communication signals can be judged according to the sent quantity, whether the reason for the reduction of the success rate of uplink data transmission is poor in signal strength between the master earphone and the terminal equipment or poor in signal strength between the master earphone and the slave earphone can be judged by combining the received quantity, and further dynamic adjustment of communication time slots is achieved.

Step 603, sending a time slot adjustment notification to the terminal device and the slave earphone according to the time slot ratio.

According to the communication time slot allocation method, the communication signal intensity change between the master earphone and the terminal equipment can be judged according to the sent quantity and the received quantity of the preset time, the time slot ratio of the first time slot allocated to the terminal equipment to the second time slot allocated to the slave earphone is further determined, the time slot adjustment notification is sent according to the time slot ratio, the terminal equipment and the slave earphone are informed of time slot allocation adjustment, the communication bandwidth of interaction between the master earphone and the slave earphone and the terminal equipment respectively is dynamically adjusted, and the stability of data transmission is improved.

In one embodiment, if the transmitted number is less than the transmission amount threshold and the received number is not less than the reception amount threshold, the slot ratio is determined as a first preset slot ratio.

The transmission amount threshold is the number of binaural data packets to be transmitted in a preset time when communication signals between the master earphone and the terminal device and between the master earphone are normal. The reception amount threshold is the number of the received slave ear data packets within a preset time when the communication signal between the master earphone and the slave earphone is normal.

When the transmitted number of the binaural data packets is smaller than the transmission amount threshold, the success rate of transmitting the binaural data packets may be reduced due to poor communication signals between the master earphone and the terminal device; it may also be that the number of slave recording packets is insufficient due to poor communication signals between the master earphone and the slave earphone, resulting in a reduced number of generated binaural data packets and thus reduced transmitted binaural data packets. The reason can be determined by judging the received number of the slave recording data packets in combination with the master earphone in the preset time. If the received number is not less than the threshold of the received amount, that is, the communication signal between the slave earphone and the master earphone is normal, the transmission success rate of the binaural data packet is reduced because the communication signal between the master earphone and the terminal device is poor, so that the duty ratio of the first time slot needs to be increased, and the time slot ratio should be determined as the first preset time slot ratio.

In one embodiment, if the transmitted number is less than the transmission amount threshold and the received number is less than the reception amount threshold, the slot ratio is determined to be a second preset slot ratio.

When the transmitted number is smaller than the transmission amount threshold, if the received number is smaller than the reception amount threshold, that is, the communication signal between the slave earphone and the master earphone is poor, the received amount of the slave recording data packet is reduced, and the transmission amount of the binaural data packet is reduced, so that the duty ratio of the second time slot needs to be increased, and the time slot ratio should be determined as a second preset time slot ratio. Wherein the second preset time slot ratio is smaller than the first preset time slot ratio.

In one embodiment, if the number of transmitted transmissions is not less than the threshold transmission amount, the slot ratio is determined to be a third preset slot ratio.

When the transmitted number is not less than the threshold of the transmission amount, that is, the communication signals of the master earphone, the terminal device and the slave earphone are normal, the received number at the moment is not necessarily less than the threshold of the reception amount, so that the time slot ratio corresponding to the normal signal strength can be selected, and the time slot ratio can be determined as a third preset time slot ratio. In one embodiment, since the data amount of the single binaural data packet is obviously larger than the data amount of the single slave recording data packet, a certain communication bandwidth needs to be allocated to the terminal device appropriately in order to ensure the data transmission stability, so that the third preset time slot ratio larger than the second preset time slot ratio and smaller than the first preset time slot ratio can be selected.

As shown in fig. 7, the embodiment of the present application further provides a data transmission method, which is applied to a master earphone in an earphone set, where the earphone set further includes a slave earphone; the method comprises the following steps:

in step 701, a slave recording packet sent from the headset is received in a second time slot.

In step 702, if the buffered master recording data packet is synchronized with the slave recording data packet, the master recording data packet is included with the slave recording data packet and a binaural data packet is generated.

The synchronization refers to that the master recording data packet and the slave recording data packet correspond to audio data within the same time, and specifically can be judged through sequence number comparison, time frame comparison or other synchronization comparison methods.

In step 703, the binaural data packet is transmitted to the terminal device in the first time slot.

The time slot ratio of the first time slot to the second time slot is determined according to the communication time slot allocation method.

In this embodiment, the master earphone and the slave earphone are used for recording respectively, and then the master earphone is used for synchronously comparing the audio data recorded by the master earphone and the slave earphone to generate true stereo recording data, the true stereo recording data is sent to the terminal equipment, the true sound field is restored, and meanwhile, the first time slot and the second time slot are dynamically adjusted, so that stable data transmission is ensured, the recording effect is ensured, and the problem of intermittent recording is avoided.

As shown in fig. 8, in one embodiment, the data transmission method further includes the steps of:

step 801, comparing the first synchronization information of the master recording data packet with the second synchronization information of the slave recording data packet, and judging whether the first synchronization information and the second synchronization information are matched.

The first synchronization information is identification information added to the recorded audio data by the main earphone; the second synchronization information is identification information added to the recorded audio data from the headphones. The first synchronization information and the second synchronization information may be information for identifying time frames, or sequence number information for identifying recording sequence

In one embodiment, the first synchronization information and the second synchronization information are added before encoding the audio data. In this embodiment, the master earphone needs to compare the second synchronization information obtained after decoding the slave recording data packet with the first synchronization information, and then encode the synchronized master recording data packet and slave recording data packet to generate the binaural data packet.

In one embodiment, the first synchronization information and the second synchronization information are added after encoding the audio data. In this embodiment, the master earphone may directly compare the synchronization information of the received encoded slave recording data packet, and if the comparison is synchronous, the master recording data packet and the slave recording data packet are directly combined into the binaural data packet to be sent, so that the data processing process of the master earphone is reduced, and the data transmission efficiency is improved.

Step 802, if the first synchronization information matches the second synchronization information, determining that the master recording data packet is synchronized with the slave recording data packet.

Step 803, if the first synchronization information and the second synchronization information are not matched, another slave recording data packet is obtained and compared with the master recording data packet until the master recording data packet is matched with the synchronized slave recording data packet.

Taking the first synchronization information and the second synchronization information as serial numbers for illustration, wherein the first synchronization information and the second synchronization information are serial numbers allocated to a master earphone and a slave earphone based on the sequence of data packets generated by recording respectively, when the master earphone performs synchronization comparison, the master earphone extracts a master recording data packet with the minimum serial number from a master cache area, and performs serial number comparison of a slave recording data packet with the minimum serial number from a slave cache area, if the serial numbers are consistent, the synchronization is judged, if the serial numbers are inconsistent, the serial number comparison of a slave recording data packet with the next serial number is extracted from the slave cache area, until the synchronous slave recording data packet is found, or the comparison is stopped when all the slave recording data packets are found, and the synchronization comparison is tried again after waiting for a certain time.

The embodiment adopts a synchronous information comparison mode to judge whether the main recording data packet is matched with the auxiliary recording data packet, and has simple judging process and easy execution.

As shown in fig. 9, the embodiment of the present application further provides a communication time slot allocation method, which is applied to the system shown in fig. 1; the method comprises the following steps:

step 901, determining a time slot ratio of a first time slot to a second time slot by a master earphone according to the number of the cached master recording data packets and the number of slave recording data packets;

in step 902, the master earphone sends a slot adjustment notification according to the slot ratio.

In step 903, the terminal device adjusts the timeslot allocation when it monitors the timeslot adjustment notification, so as to receive, in the first timeslot, the binaural data packet sent by the master earphone.

Step 904, the slave earphone adjusts the time slot allocation when the slave earphone monitors the time slot adjustment notification to transmit the slave recording data packet to the master earphone in the second time slot.

The time slot is the data transmission time allocation agreed between two communication ends, when the main earphone determines that the time slot ratio needs to be adjusted, besides self-adjusting the time slot allocation, the main earphone also needs to inform the auxiliary earphone and the terminal equipment to make corresponding adjustment.
