Problems solved by technology

[0004] In response to the above problems, a patent titled charging box, earphones, computer storage media and earphone power upload method in the earphone charging system (patent number: 201810652152.8) came into being, but the method of earphone power upload described in this invention Only through the COM terminal, this method is more prone to data errors and affects the accuracy of the data. On the other hand, this method is only used for the charging box to query the power in the earphones, and cannot realize the charging box to send its own power to the earphones. It is more difficult to realize that the charging box sends its own power information to the VG device through the earphone

Embodiment 1

[0054] The charging box sends the information that the charging box is opened to the TWS headset

[0055] 1) The charging box sends a communication code to the TWS headset through the Vcharge terminal;

[0056] 2) The TWS earphone analyzes the communication code, and sends a reply code to the charging box through the COM terminal after the communication code is effectively interpreted;

[0057] 3) The charging box judges whether the reply code is received within 350ms. If yes, the charging box judges that the communication code has been effectively interpreted, and then ends the communication; if not, the charging box judges that the TWS headset has not received the communication code, and then enters the next step ;

[0058] 4) The charging box judges whether the number of consecutive communication codes sent to the TWS earphone is more than three times, if yes, end the communication, if not, return to step 2).

[0059] The communication code includes a guide code, a data c...

Embodiment 2

[0061] The charging box sends a message that the charging box is closed to the TWS headset

[0062] 1) The charging box sends a communication code to the TWS headset through the Vcharge terminal;

[0063] 2) The TWS earphone analyzes the communication code, and sends a reply code to the charging box through the COM terminal after the communication code is effectively interpreted;

[0064] 3) The charging box judges whether the reply code is received within 350ms. If yes, the charging box judges that the communication code has been effectively interpreted, and then ends the communication; if not, the charging box judges that the TWS headset has not received the communication code, and then enters the next step ;

[0065] 4) The charging box judges whether the number of consecutive communication codes sent to the TWS earphone is more than three times, if yes, end the communication, if not, return to step 2).

[0066] The communication code includes a guide code, a data code, a...

Embodiment 3

[0068] The user double-clicks the reset button on the earphone box, and the charging box sends a message to the TWS earphone to enter the pairing mode

[0069] 1) The charging box sends a communication code to the TWS headset through the Vcharge terminal;

[0070] 2) The TWS earphone analyzes the communication code, and sends a reply code to the charging box through the COM terminal after the communication code is effectively interpreted;

[0071] 3) The charging box judges whether the reply code is received within 350ms. If yes, the charging box judges that the communication code has been effectively interpreted, and then ends the communication; if not, the charging box judges that the TWS headset has not received the communication code, and then enters the next step ;

[0072] 4) The charging box judges whether the number of consecutive communication codes sent to the TWS earphone is more than three times, if yes, end the communication, if not, return to step 2).

Abstract

The invention discloses a two-way communication method between a TWS earphone and a charging box, including the TWS earphone and the charging box. The method includes the following steps: 1) three pins of the TWS earphone are respectively connected to corresponding three terminals in the charging box; 2) ) Send the communication code; 3) Analyze the communication code, and send the reply code after the communication code is effectively interpreted; 4) Determine whether the reply code is received within the specified time, if so, then T judges that the communication code has been effectively interpreted, Then end the communication; if not, judge that the communication code has not been received, and then go to the next step; 5) judge whether the number of times the communication code has been sent continuously is greater than three times, if so, end the communication, if not, return to step 2); among them, TWS The headset sends a communication code to the charging box through the COM terminal, and the charging box sends the communication code to the TWS headset through the Vcharge terminal. The invention can realize two-way communication between the TWS earphone and the charging box, effectively improve the degree of UI interaction between the TWS earphone and the charging box, and effectively improve the accuracy of interactive data.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a two-way communication method between a TWS earphone and a charging box. Background technique [0002] TWS earphones, also known as true wireless earphones, refer to the wireless connection between two earphones and between earphones and mobile devices without any wired communication. TWS earphones are the mainstream development trend of earphones in the future. At present, giants including Huawei, Harman International, and Apple have joined the R&D and design of TWS earphones. [0003] The trend of TWS earphones is that the size, structure, and appearance should be as simple and compact as possible, and the lower the cost, the better. For traditional TWS earphones, when charging, the connection terminals between the charging box and the left and right earphones generally have only two pin points, that is, VCC / GND (the connection terminal on the charging box is called the pow...
