Embodiment Construction

[0033] See figure 1 , figure 1 It is a schematic diagram of the circuit connection after the left / right earphone is inserted into the charging box. The left side of the figure is the charging control module of the charging box, and both the left earphone and the right earphone are TWS earphones.

[0034] In the charging control module, the charging management circuit of the charging box is an existing technology, which takes power from the battery of the charging box, converts the power of the current, and sends it to the COM public line. In order to ensure unidirectional conduction charging and step-down protection, a diode D1 is connected in series between the charging management circuit of the charging box and the COM common line, and the cathode of the diode is connected to the COM common line.

[0035] The charging control module is provided with a charging box MCU, which is the initiator for charging control and communication control. The MCU of the charging box takes ...

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...
