- Claim: 1. A TWS earphone interaction method, wherein the TWS earphones comprise a main earphone and a secondary earphone, wherein the method comprises: when the main earphone and the secondary earphone receive a data packet sent by an audio source, performing, by the main earphone and the secondary earphone, data interaction within a first residual slot of a first data transmission slot, wherein the first residual slot is a remaining of the first data transmission slot after the data packet is transmitted; when a data packet is received and the main earphone sends acknowledgment information to the audio source, performing, by the main earphone and the secondary earphone, data interaction within a second residual slot of a first next data transmission slot, wherein the second residual slot is a remaining of the first next data transmission slot after the acknowledgment information is sent; when a data packet is received and the main earphone sends acknowledgment information and extra information to the audio source, within a residual slot of a second next data transmission slot, performing, by the main earphone and the secondary earphone, data interaction within a third residual slot of a second next data transmission slot, wherein the residual slot is a remaining of the second next data transmission slot after the acknowledgment information and extra information is sent; and when the main earphone does not correctly receive audio data sent by the audio source, performing, by the main earphone and the secondary earphone, data interaction within a fourth residual slot of a third next data transmission slot, wherein the fourth residual slot is remaining of the third next data transmission slot minus a feedback time of the main earphone; wherein the feedback time of the main earphone is equal to the duration used by the main earphone to send the acknowledgment information.
- Claim: 2. The TWS earphone interaction method according to claim 1 , wherein interactive data transmitted between the main earphone and the secondary earphone includes one or more of received signal strength, signal-to-noise ratio, packet error rate, timing information, control information, customized data package/function package, audio data, audio data synchronization information, and data indicating whether or not the audio data is received correctly.
- Claim: 3. The TWS earphone interaction method according to claim 2 , wherein based on durations of the first, second, third, or fourth residual slots, and the timing and period of the interactive data, the interactive data is determined to be of a certain type.
- Claim: 4. The TWS earphone interaction method according to claim 2 , wherein based on durations of the first, second, third or fourth residual slots and the type of the interactive data, an RF frequency point of the interactive data and receiving and sending time points of the interactive data are determined.
- Claim: 5. The TWS earphone interaction method according to claim 1 , wherein communication between the main earphone and the secondary earphone is based on a Bluetooth protocol or a non-Bluetooth protocol.
- Claim: 6. TWS earphones, comprising a main earphone and a secondary earphone, wherein the main earphone and the secondary earphone use one or more residual slots for data interaction as follows: 1) When the main earphone and the secondary earphone receive a data packet sent by an audio source, the main earphone and the secondary earphone use a first residual slot of a data transmission slot, wherein the first residual slot is remaining of the data transmission slot after the data packet is transmitted; 2) When a data packet is received and the main earphone sends acknowledgment information to the audio source, the main earphone and the secondary earphone use a second residual slot of a first next data transmission slot, wherein the second residual slot is a remaining of the first next data transmission slot after the acknowledgment information is sent; 3) When a data packet is received and the main earphone sends acknowledgment information and extra information to the audio source, the main earphone and the secondary earphone use a third residual slot of a second next data transmission slot, wherein the third residual slot is a remaining of the second next data transmission slot after the acknowledgment information and the extra information is sent; and 4) When the main earphone does not receive audio data sent by the audio source correctly, the main earphone and the secondary earphone use a fourth residual slot which is a remaining of a third data transmission slot; wherein based on durations of the residual slots, and timing and period of the interactive data transmitted between the main earphone and the secondary earphone, the interactive data is determined to be of a certain type.
- Claim: 7. The TWS earphones according to claim 6 , wherein the interactive data transmitted between the main earphone and the secondary earphone includes one or more of received signal strength, signal-to-noise ratio, packet error rate, timing information, control information, customized data package/function package, audio data, audio data synchronization information, and data indicating whether or not the audio data is received correctly.
- Claim: 8. The TWS earphones according to claim 6 , wherein based on durations of the residual slots and the type of the interactive data, an RF frequency point of the interactive data and receiving and sending time points of the interactive data are determined.
- Claim: 9. A TWS earphone interaction system, comprising TWS earphones and an audio source, wherein the audio source sends data packages to the TWS earphones, wherein the TWS earphones comprise a main earphone and a secondary earphone, wherein the main earphone and the secondary earphone are used for data interaction in one or more residual slots as follows: 1) When the main earphone and the secondary earphone receive a data packet sent by an audio source, the main earphone and the secondary earphone use a first residual slot of a data transmission slot, wherein the first residual slot is remaining of the data transmission slot after the data packet is transmitted; 2) When a data packet is received and the main earphone sends acknowledgment information to the audio source, the main earphone and the secondary earphone use a second residual slot of a first next data transmission slot, wherein the second residual slot is a remaining of the first next data transmission slot after the acknowledgment information is sent; 3) When a data packet is received and the main earphone sends acknowledgment information and extra information to the audio source, the main earphone and the secondary earphone use a third residual slot of a second next data transmission slot, wherein the third residual slot is a remaining of the second next data transmission slot after the acknowledgment information and the extra information is sent; and 4) When the main earphone does not receive audio data sent by the audio source correctly, the main earphone and the secondary earphone use a fourth residual slot which is a remaining of a third next data transmission slot; wherein based on durations of the residual slots, and timing and period of interactive data transmitted between the main earphone and the secondary earphone, the interactive data is determined to be of a certain type.
