Abstract

The invention discloses an earphone charging device, box and system. The earphone charging device comprises a storage battery, a charging box main circuit, an earphone charging interface, a charging box charging interface and a switching circuit, the power input end of the charging box main circuit and the controlled end of the switching circuit are connected with the charging box charging interface, the power output end of the charging box main circuit is connected with the power input end of the switching circuit, and the power output end of the switching circuit is interconnected with the earphone charging interface and the storage battery. When the earphone charging device carries out charging via the charging box charging interface, the switching circuit is switched on, and DC power undergoes charging management by the charging box main circuit and then output to the storage battery; and when the earphone charging device does not carry out charging, the switching circuit is switched off, the storage battery is isolated from the charging box main circuit, and the charging box main circuit does not work. The problems of electric energy loss and electrostatic interference when the circuit in the earphone charging box is in the work state for long time are solved.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an earphone charging device, an earphone charging box and an earphone charging system. Background technique [0002] TWS (True Wireless Stereo, True Wireless Stereo) earphones do not need a wired connection. The left and right earphones form a stereo system through Bluetooth, which is popular among consumers for listening to music and talking. Currently, there are more and more TWS earphones on the market. The more there are, the more corresponding charging boxes will be. [0003] However, there is a problem with the current charging box, that is, the earphone is still in working state when it is not charging, that is, the battery is connected to the back-end circuit, and the back-end circuit is in working state all the time. [0004] On the one hand, this increases the standby power consumption of the earphone charging box, and also causes unnecessary power consumption. [0...
