PROBLEM TO BE SOLVED: To provide a mobile phone auxiliary device which is simplified in configuration further, and a mobile phone which is simplified in configuration further.SOLUTION: An upper part of a soft cover which covers a normal mobile phone is made thick, an electromagnetic vibrator which becomes a cartilage conduction vibration source is disposed in one corner, an external earphone plug which is inserted into an external earphone jack of a mobile phone is provided in the other corner, and the cartilage conduction vibration source is driven by audio signals outputted from the external earphone jack. Before the mobile phone is covered with the soft cover, the soft cover can be inserted into an external output jack. The soft cover includes a driving section of the cartilage conduction vibration source and a power supply section which feeds power to the driving section. A cartilage conduction vibration section is provided in one of upper corners of the mobile phone, cartilage conduction can be performed both from a front side and from a rear side by contact to the corners, and a microphone having directivity which is symmetric at the front side and the rear side is provided on a side face or a bottom face. |
