| 摘要 | There is disclosed in the present specification a mobile telephone in which a cartilage conduction unit for making contact with the ear cartilage is provided to at least one of two corner parts at an upper side of the mobile telephone. Further disclosed is a mobile telephone comprising 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. Further disclosed is a mobile telephone comprising: a telephone function unit; a cartilage conduction vibration source; an application processor for controlling the telephone function unit; a power management unit for supplying a plurality of different voltages to the telephone function unit; a drive circuit for driving the cartilage conduction vibration source on the basis of the power supplied from the power management unit; and a controller for controlling the power management unit and the drive circuit on the basis of an instruction from the application processor; the power management unit, the drive circuit, and the controller being configured as a single-chip integrated circuit. | ||||||
