Method and apparatus for establishing single line connection, wireless earphone and charging box

Abstract

The invention discloses a method for establishing a single line connection, and relates to the technical field of portable listening devices. The method is used for solving the problem that the communication between an existing wireless earphone and a charging box is unreliable, which is not conducive to the user experience. The method comprises the following steps: judging, by a wireless earphone, whether a power supply contact point of a charging box is in a communication mode, wherein a charging contact point of the wireless earphone is connected with the power supply contact point of the charging box; and if yes, switching the charging contact point from a charging mode to the communication mode, and establishing the single line connection with the charging box. According to the methoddisclosed by the invention, the charging contact point of the wireless earphone is connected with the power supply contact point of the charging box to establish the single line connection between the wireless earphone and the charging box, so that the wireless earphone and the charging box can perform information interaction through the single line connection, thereby improving the communicationreliability of the charging box and the wireless earphone, and improving the user experience. In addition, the invention further discloses an apparatus for establishing the single line connection, awireless earphone, a TWS earphone and a charging box, which also have the above beneficial effects.

Description

technical field

[0001] The invention relates to the technical field of portable listening devices, in particular to a method and device for establishing a single-wire connection, a wireless earphone, a TWS earphone and a charging box. Background technique

[0002] Headphones are a pair of conversion units used to receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears.

[0003] Current earphones can be divided into wired earphones and wireless earphones. Among them, wired earphones require two left and right earphones to form a left and right sound channel through a wired connection to produce a stereo effect, which is very inconvenient to wear. The wireless headset communicates with the terminal through a wireless communication protocol (such as Bluetooth). Compared with wired headsets, it has the characteristics of no need to pack data cables and is easy to use. Among them, the latest true wirel...
