摘要： An earphone including an audio play portion (30), a body (12) where a printed circuit board (14), a plug (15), and a socket (16) are installed, and a connecting wire (40). The plug (15), the socket (16), and the connecting wire (40) are in electrical connection with the printed circuit board (14). The plug (15) is configured to be adapted to a lightning interface (22) integrated with an audio output and a power input, and the audio play portion (30) and the socket (16) are in electrical connection with the plug (15) and capable of work simultaneously and being respectively configured to play music and charge when the plug (15) is inserted into the lightning interface (22). The earphone utilizes the plug (15) to be adapted to the lightning interface (22) integrated with the audio output and the power input. By setting the socket (16) and the audio play portion (30) in connection with the body to be capable of working simultaneously and by allowing the socket (16) and the audio play portion (30) to respectively be configured to audio transmission and charge, the music listening and charging can be simultaneously achieved.
