[0058] Based on the same inventive concept, the second embodiment of the present invention is a TWS earphone presence detection system, the system includes a charging box and a TWS earphone;

[0059] The charging box is used to send a power-on signal to the TWS earphone, and stop charging the TWS earphone;

[0060] The TWS earphone is used to power on when the power-on signal is received, and periodically collect the Vbus voltage value of the TWS earphone in the power-on state;

[0061] The TWS earphone is used to compare the collected Vbus voltage value with the preset charging stop voltage value, and when the Vbus voltage value is greater than or equal to the charging stop voltage value, it is determined that the TWS earphone is charging Otherwise, it is determined that the TWS earphone is not in the charging box.

[0062] In this embodiment, the charging box has a built-in Hall switch;

[0063] When the charging box determines that the charging box is opened through the H...

Abstract

The invention discloses a method and system for detecting the presence of a TWS earphone. The method includes: a charging box sends a power-on signal to the TWS earphone, and stops charging the TWS earphone; when the TWS earphone receives the power-on signal Power on, and periodically collect the Vbus voltage value of the TWS earphone in the power-on state; the TWS earphone compares the collected Vbus voltage value with the preset charging stop voltage value, and when the Vbus voltage value is greater than or equal to When the charging stop voltage value is reached, it is determined that the TWS earphone is in the charging box; otherwise, it is determined that the TWS earphone is not in the charging box. The invention can actively identify whether the TWS earphone is in the charging box, and can provide technical support for some functions that need to identify whether the TWS earphone is in the charging box, and the invention has low implementation cost and high detection reliability.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a TWS earphone presence detection method and system. Background technique [0002] With the development of wireless communication technology, users usually choose wireless earphones when listening to audio and video or answering calls. True Wireless Stereo (TWS) earphones that can achieve wireless separation of left and right channels are common in the market today. Bluetooth wireless headset. The TWS earphone can connect the mobile terminal to the main earphone (such as the left earphone) through Bluetooth wireless mode, and the master earphone is then connected to the slave earphone (such as the right earphone) through Bluetooth wireless mode to realize the real wireless separation of the left and right audio channels of the earphone , Eliminate the connecting wires between the ears of traditional earphones and even Bluetooth earphones, making it easier to wear. [0003] At...
