The present invention relates to an audio device applied to land or water transportation means such as a vehicle, vessel, or the like, and more specifically, to an audio device to be mounted on the transportation means. The audio device has improved convenience enabling an MP3 file stored in a mobile phone or additional USB memory of a user to be output, depending on existing broadcast or charge or needs of the mobile phone. Also, since a waterproof function of the audio device is required when the audio device is applied to a water transportation means such as a vessel, a water tight structure for a connection part of a wiring, which is the most vulnerable to water tightness, is improved, thereby improving the waterproof function. The audio device according to the present invention comprises: an MP3 application (100); at least one USB port (200); and a wiring water tight means (300). |
