Embodiment approach

[0051] In one embodiment, if the other headset does not receive the first frame sent by the one headset and the other headset does not receive the third frame sent by the one headset Send a NACK response packet to another device (denoted as steps ). In another embodiment, if it is determined that the selected one earphone has not correctly received the Bluetooth audio data frame (the result of step 603 is "No"), and it is determined that it has not correctly received the packet header of the Bluetooth audio data frame (step 604 ) The result is "No"), then the one headset sends a NACK response packet to the other device. The two implementations will not be implemented simultaneously, only one may be selected.

[0052] Different sub-modes of Bluetooth communication can be used for wireless headsets and smart devices for different application scenarios. The wireless earphones and the communication methods thereof according to various embodiments of the present disclosure will...

Abstract

The invention relates to a wireless earphone and a communication method for the wireless earphone. The wireless earphone comprises a master earphone and a slave earphone, and the master earphone establishes a Bluetooth link with another device to perform Bluetooth communication with the other device and to transmit relevant parameters of the Bluetooth link to the slave earphone, so that the slaveearphone monitors a Bluetooth signal from the other device. One earphone is configured to: in the case that a packet header of a Bluetooth audio data frame is correctly received but the Bluetooth audio data frame is not correctly received, send a first frame only comprising the information of the correctly received packet header of the Bluetooth audio data frame to the other earphone; and the other earphone is configured to: in the case that the Bluetooth audio data frame is correctly received and the first frame is received, send a second ECC frame to the one earphone. By adoption of the communication method for the wireless earphone, the reliability of Bluetooth transmission can be improved; the retransmission of audio data frame is reduced; and the synchronism of the Bluetooth audio data frame can be improved to optimize the stereo effect.

Description

technical field [0001] The present disclosure relates to earphones and communication methods for earphones, and more particularly, to wireless earphones and communication methods for wireless earphones. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones have become an indispensable daily necessities for people. Traditional wired earphones are connected to smart devices (such as smartphones, laptops, tablets, etc.) through wires, which will restrict the wearer's movement, especially in sports situations. At the same time, the winding and pulling of the headphone cable, as well as the stethoscope effect all affect the user experience. Ordinary Bluetooth headsets cancel the connection between the headset and the smart device, but there is still a connection between the left and right ears. [0003] True wireless stereo headphones came into being. The current communication method of true wireless earphones is...
