PROBLEM TO BE SOLVED: To provide a mobile phone which can be used more easily.SOLUTION: A mobile phone has: a housing structure; a cartilage conduction vibration section which is held in the housing structure and transmits a cartilage conduction vibration to the surface of the housing structure; and a touch panel operation surface. The cartilage conduction vibration section is vibrated due to cartilage conduction when the surface of the housing structure contacts an ear cartilage and is vibrated due to feedback of a touch panel operation feeling when a finger touches the touch panel operation surface. The mobile phone has an impact detection object surface. The cartilage conduction vibration section is held in the housing structure in a direction where the main vibration direction is substantially orthogonal to the impact detection object surface. The cartilage conduction vibration section is commonly used for vibration for an incoming call notification. The mobile phone has a horizontal still state detection section which detects a horizontal still state. When the horizontal still state is detected, vibration of the cartilage conduction vibration section is stopped. |
