VR headband having audio, data transmission, and charging functions, and control circuit

Disclosed is a VR headband having audio, data transmission, and charging functions, and a control circuit. The VR headband includes a headband body and a power storage component, a transmission line, and an earphone integrally disposed on the headband body. The control circuit includes a DSP audio circuit, a data transmission circuit, a charging circuit, and a discharging circuit. The DSP audio circuit is configured to perform signal optimization on audio data inputted by VR glasses; the data transmission circuit is configured to convert a differential signal inputted by a USB-C base on the power storage component; the charging circuit is configured to buck a high voltage inputted by the USB-C base; and the discharging circuit is configured to boost a voltage outputted by the rechargeable battery. The present invention has the advantages of convenient charging, data transmission, and audio reception of the VR glasses.
