Charging box and headset in headset charging system, computer storage medium and method for uploading power for headset

Abstract

The invention relates to the field of headset charging, in particular to a charging box and headset in a headset charging system. A charging box charging management circuit provides a COM common linewith power; a common pin of a charging box MCU is connected with the COM common line; a GND pin of the charging box MCU is connected with a GND line; a headset charging management circuit takes the power from a COM' common line; a common pin of a headset MCU is connected with the COM' common line; the GND pin of the headset MCU is connected with a GND' line; an input end of the headset charging management circuit is also connected to the COM' common line through a capacitor C2; when the headset is inserted into the charging box, powered terminals on the headset are butted with power supply terminals on the charging box, so that the COM common line conducts the COM' common line and the GND line conducts the GND' line; normal power supply and data interaction are carried out between the charging box and the headset through the COM common line and the COM' common line; and when level of the COM' common line is lowered, the capacitor C2 is slowly discharged to the headset charging management circuit and the headset charging management circuit is charged for a while, thereby ensuring uninterrupted power supply for the charging box and the headset during data interaction.

Description

technical field [0001] The invention relates to the field of earphone charging, in particular to a charging box and an earphone of an earphone charging system. The charging box and the earphone each have a computer storage medium, and each computer storage medium has a program executable by an MCU. 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 righ...

Problems solved by technology

In the prior art, in order to communicate between the charging box and the headset, it is often necessary to add additional pin points, such as 4 pin points, in addition to the two power supply lines, two additional lines are added for communication design, but this structural design, It will greatly affect the aesthetics of the structure, and the cost of materials will also increase
