The present disclosure provides a TWS earphone interaction method and system, and TWS earphones. When a main earphone and a secondary earphone receive a data packet sent by an audio source, within a residual slot of a data transmission slot, the main earphone and the secondary earphone can perform data interaction, wherein the residual slot is the remaining data transmission slot after the data packet is transmitted. When a data packet is received, the main earphone sends acknowledgment information to the audio source, within a residual slot of a next data transmission slot, the main earphone and the secondary earphone can perform data interaction, wherein the residual slot is the remaining of the next data transmission slot after the acknowledgment information is sent.

The present disclosure provides a TWS earphone communication method and system, and TWS earphones. The method includes: when an audio source sends a data packet and a main earphone correctly receives the data packet, the main earphone sends acknowledgment information in an acknowledgment information slot; when the data packet is incorrectly received by the main earphone, no information is sent in the acknowledgment information slot; and when the data packet is received correctly by a secondary earphone, the secondary earphone does not send any information in the acknowledgment information slot. When the data packet is not received correctly by the secondary earphone, it sends interference information in the acknowledgment information slot.

The present disclosure provides a method and system for synchronous audio playback of TWS earphones, The TWS earphones include a master earphone and a slave earphone; both the master earphone and the slave earphone include a first timer, a second timer, an audio DAC, and an audio playback phase-locked loop; the first timer and the second timer of the master earphone are respectively used to collect a real-time audio playback position of the master earphone and a public Bluetooth clock; the first timer and the second timer of the slave earphone are respectively used to collect a real-time audio playback position of the slave earphone and a local Bluetooth clock; the slave earphone calibrates audio data in the audio DAC, and the first timer and the audio playback phase-locked loop of the slave earphone, to achieve synchronization between the master earphone and the slave earphone.
