Abstract

The invention discloses a TWS earphone based on a monitoring scheme and an implementation method thereof, and the earphone comprises a main earphone which is in communication connection with an intelligent device, adds a timestamp to a received data packet through a Bluetooth clock, obtains corresponding SEQN information, obtains a set of {SEQN, timestamp} of an auxiliary earphone for representingthe receiving condition of the data packet, and transmits the data packet to the intelligent device according to the set of {SEQN, timestamp}, finds out a lost packet of the auxiliary earphone according to the timestamp and the SEQN information and sends the lost packet to the auxiliary earphone; the auxiliary earphone which is used for adding timestamps to the data packets received in the monitoring link through a Bluetooth clock, obtaining corresponding SEQN information, representing the data packet receiving condition of each received data packet through a set of {SEQN, timestamps}, sending the set of {SEQN, timestamps} to the main earphone after receiving a request of the main earphone, and sending the set of {SEQN, timestamps} to the main earphone; and inserting the lost packet withthe timestamp forwarded by the main earphone into the received data packet sequence when the lost packet with the timestamp forwarded by the main earphone is received.

Description

technical field

[0001] The invention relates to the technical field of TWS earphones, in particular to a TWS earphone based on a monitoring scheme and an implementation method thereof. Background technique

[0002] With the progress of society and the development of communication technology, earphones have become an indispensable daily necessities in people's lives. Among them, Bluetooth earphones apply Bluetooth technology to hands-free earphones, allowing users to avoid the entanglement of earphone cables. Feel comfortable using your headphones in a variety of ways.

[0003] At present, the True Wireless Stereo (TWS) Bluetooth headset has completely got rid of the shackles of the connecting wire. The left and right sides of the TWS headset are equipped with independent Bluetooth, so that the TWS headset has a truly separated left and right channel. The TWS headset includes the main headset and Secondary earphones, currently there are two main transmission schemes for TWS ...

Examples

Embodiment

[0101] In this embodiment, the implementation process of a TWS earphone based on the monitoring scheme is as follows:

[0102] Step A, the primary and secondary earphones add time stamps to the received data packets, and obtain corresponding SEQN information.

[0103] Step B, the primary earphone sends a request to the secondary earphone to obtain a set of {SEQN, time stamp} from the secondary earphone end indicating its data packet reception status. In this embodiment, when the main earphone judges that it has received 4 data packets, it will send a request to the secondary earphone, and the secondary earphone will feed back the reception status of the local end to the main earphone in the form of {SEQN, time stamp}.

[0104] Step C, the primary earphone finds out the lost packet according to the time stamp and the SEQN information and sends it to the secondary earphone.
