Abstract

The invention discloses a TWS earphone based on a monitoring scheme and its implementation method. The earphone includes: a main earphone, which communicates with an intelligent device, adds a time stamp to a received data packet with a Bluetooth clock and obtains corresponding SEQN information, and acquires The pair of earphones indicates the collection of {SEQN, timestamp} of the data packet reception situation, according to the set of {SEQN, timestamp}, find out the lost packet of the pair of earphones according to the timestamp and SEQN information and send it to the pair of earphones; the pair of earphones, for the monitoring chain The data packet received on the road adds a time stamp with the Bluetooth clock and obtains the corresponding SEQN information, and the information of each data packet received is represented by a set of {SEQN, time stamp}. After the request of the earphone, the {SEQN, time stamp} set is sent to the main earphone, and when the lost packet with the time stamp forwarded by the main earphone is received, it is inserted into the sequence of received data packets.

Description

technical field

[0001] The present 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 development of social progress and communication technology, earphones have become an indispensable daily necessities in people's lives. Among them, bluetooth earphones apply bluetooth technology to hands-free earphones, so that users can avoid the shackles of earphone cables. Feel free to use the headset in a variety of ways.

[0003] At present, True Wireless Stereo (TWS) Bluetooth headsets are completely free from the shackles of connecting cables. The left and right TWS headsets are equipped with independent Bluetooth, so that the TWS headsets have truly separated left and right channels. The TWS headset includes the main headset and Secondary earphones, there are two main transmission schemes for TWS earphones: forwarding and monitoring. In ...

Examples

Embodiment

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

[0102] In step A, the primary and secondary earphone terminals add a timestamp to the received data packet, and obtain the corresponding SEQN information.

[0103] In step B, the primary earphone sends a request to the secondary earphone to obtain a set of {SEQN, timestamp} representing the reception status of its data packets at the secondary earphone end. In this embodiment, when the main earphone determines that four data packets are received, it sends a request to the secondary earphone, and the secondary earphone feeds back the reception status of the local end to the main earphone as a set of {SEQN, timestamp}.

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