Abstract

A mobile telephone includes a cartilage conduction unit for making contact with the ear cartilage. The cartilage conduction unit is provided to at least one of two corner parts at an upper side of the mobile telephone. The mobile telephone can include a surface of an outer wall and a cartilage conduction vibration source arranged inward from the surface of the outer wall, the vibration of the cartilage conduction vibration source being transmitted to the surface of the outer wall, wherein when the surface of the outer wall is brought into contact with at least a part of the ear cartilage around the entrance part to the external auditory meatus without making contact with the auricular helix, the sound pressure inside the external auditory meatus at about 1 cm from the entrance part of the external auditory meatus has an at least 10 dB increase compared to the non-contact state.
