Claim 0:
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.
