A telephone includes: a housing; a voice output device that is placed inside the housing and produces voice; a contact detection unit that detects a position of an object that contacts the housing; a position offset calculation unit that calculates a distance between the contact position of the object detected by the contact detection unit and the voice output device; and a voice adjustment unit that adjusts the voice produced from the voice output device, depending on the distance.
