Abstract

The present invention provides a charging and communication circuit and method and its charging equipment, accessories and system, including: a box-side communication module, used to generate a box-side communication request signal and transmit it to the potential output terminal, and the potential of the box-side communication request signal is not It is equal to the high potential and low potential when the potential output terminal provides charging power; the path establishment module is used to disconnect the charging power output to the potential output terminal according to the communication request signal of the box terminal, so as to request the terminal connected to the potential output terminal to establish a communication connection . Therefore, the potential interference caused by the charging power source is reduced, so that when the terminal connected to the potential output terminal is requested to establish a communication connection, the identification of the communication connection request is improved, and the communication connection establishment request is more targeted and effectively initiated. .

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a charging and communication circuit and method, as well as charging equipment, accessories and systems thereof. Background technique [0002] With the development of technology, wireless headsets (such as Bluetooth headsets) are becoming more and more popular. At present, a charging box is usually configured for a wireless earphone, and most of the charging box and the wireless earphone are charged through two corresponding power contact points. There are many communication requirements between the charging box and the wireless headset, including: after the wireless headset is inserted into the charging box, the battery level of the headset is detected; the wireless headset queries the battery level of the charging box; the button pairing function on the wireless headset charging box, etc. [0003] When the existing charging box communicates with the wireless earpho...
