Mobile telephone
First Claim
1. A mobile telephone comprising a cartilage conduction unit to transmit vibration to ear cartilage through direct contact therewith,the cartilage conduction unit being located at at least one of two corner parts at an upper side of the mobile telephone,wherein when the cartilage conduction unit is brought into contact with at least one part of the ear cartilage around an 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 increase of at least 10 dB over that in the non-contact state, and the sound pressure inside the external auditory meatus at about 1 cm from the entrance part of the external auditory meatus changes by at least 5 dB increase due to a change in contact pressure;
- and, when the entrance part of the external auditory meatus is occluded by an increase in contact pressure, the sound pressure inside the external auditory meatus at about 1 cm from the entrance part of the external auditory meatus has an increase of at least 20 dB over that in the non-contact state.

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.
