Visible light communication external device and electronic device

The invention provides a visible light communication external device and an electronic device. The visible light communication external device comprises a shell, a photoelectric detector, a receivingcircuit, a sending circuit, a light source, a transmission line and an interface unit. The photoelectric detector, the receiving circuit, the sending circuit, the light source, the transmission line and the interface unit are mounted in the shell. The shell is mounted out of an electronic device body in a matchable mode. According to the visible light communication external device and the electronic device, the visible light communication external device can be mounted out of the electronic device body in the matchable mode, so the electronic device has a visible light communication function. 本申请提供了种可见光通信外置装置及电子设备，可见光通信外置装置包括：壳体、光电检测器、接收电路、发送电路、光源、传输线路和接口单元；光电检测器、接收电路、发送电路、光源、传输线路和接口单元安装于壳体内；壳体可匹配的安装在电子设备主体的外部。在本申请中，可以将可见光通信外置装置可匹配的安装在电子设备主体的外部，使电子设备具备可见光通信功能。
