The terminal utilizing bone conduction converts the voice transmitted from the other party's terminal after being converted into an electric signal into vibration. When a user of a terminal using bone conduction puts a speaker (vibration part) of the terminal on his or her skull, the vibration is transmitted to the cochlea through the skull. Therefore, even if the external ear is impaired, the voice can be transmitted to the brain without passing through the affected part.
