The circuit board includes a first grounding branch and a second grounding branch. The first grounding branch is connected in series to a first switch, and the second grounding branch is connected in series to a second switch. When the first switch is on, the first grounding branch serves as a current return path of the antenna. When the second switch is on, the second grounding branch serves as a current return path of the antenna. By controlling the on or off state of the first switch and the second switch, the Bluetooth earphone can switch ground structures of the antenna and select different current return paths for the antenna, to switch radiation patterns of the antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bluetooth earphone","description":"A Bluetooth earphone includes an antenna and a circuit board.
