Abstract

The embodiment of the invention discloses a Bluetooth earphone charging circuit and a Bluetooth earphone. The circuit comprises an earphone side connector, an earphone processor input-output port anda charging box side connector; when the earphone processor input-output port works in an output mode, the earphone processor input-output port is connected with the earphone side connector, and the earphone side connector is connected with the charging box side connector; when the earphone processor input-output port works in an input mode, the earphone processor input-output port is connected with an earphone processor input power supply via a first resistor; the charging box side connector is connected with the negative electrode of a charging box power supply via a second resistor; and thelevel state of the earphone processor input-output port is used for determining the state of the earphone. According to the Bluetooth earphone charging circuit and Bluetooth earphone provided by the embodiment of the invention, the situation that the state judgment of earphone is inaccurate when the charging box is out of power is avoided, the accuracy of state judgment of the earphone is improved, and the accurate control on the earphone is achieved, and the user experience is improved.

Description

Technical field [0001] The embodiment of the present invention relates to wireless charging technology, in particular to a Bluetooth headset charging circuit and a Bluetooth headset. Background technique [0002] Common Bluetooth headsets on the market now consist of two Bluetooth headsets and a headset charging box. The headset charging box charges the Bluetooth headset. When the Bluetooth headset is placed in the charging box, the two are electrically connected through three connectors such as pins. Let the three connectors be named connector A, connector B, and connector C. Connector A: The charging box provides charging power VBUS to the headset, such as 5V. Connector B: The headset provides indicator light control signals to the charging box. Connector C: common ground pin for earphone and charging box. [0003] In the earphone control logic, the earphone is put into the charging box, the earphone detects the VBUS high level through the connector A, it is judged that it h...
