A charging circuit of an earphone device converts an output voltage provided by a charging device into a charging voltage to charge an earphone battery when the output voltage is higher than a preset voltage. The earphone device or the charging device adjusts the output voltage to switch between a first voltage and a second voltage, so as to perform data transmission between the earphone device and the charging device, wherein the first voltage and the second voltage are higher than the preset voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Earphone charging system and charging method thereof","description":"An earphone charging system and a charging method thereof are provided.
