Abstract: An audio device where an influence of magnetic field formed by an external speaker on a magnetic sensor can be reduced is provided. When a mobile phone 2 is placed on a cradle 3 so as to fit in a recess 25, an audio signal terminal 36 of the mobile phone 2 and an audio signal terminal 22 of the cradle 3 are connected, and an audio signal of the mobile phone 2 is output from a speaker 23. The speaker 23 and a magnetic sensor such as an opened and closed sensor 42 or geomagnetism sensor 43 of the mobile phone 2 are arranged at positions not superposed on each other.
