Abstract:
1. A mobile terminal apparatus comprising: a first case that has a panel surface with a keypad; a second case that is attached to the first case so as to be movable between a closed state to cover the panel surface and an open state in which the keypad provided on the panel surface is exposed to allow the keypad to be used; a receiver that is provided on a front surface of the second case facing the panel surface of the first case and that produces air vibration when receiving a call; and a bone conduction speaker that has a vibration surface attached to the first case so as to protrude from the panel surface of the first case when the second case is in the open state and to protrude outwardly from a back surface of the second case by way of an opening in the second case when the second case is in the closed state, and that produces vibration according to a call reception signal so that the call is received by means of bone conduction, wherein the mobile terminal apparatus is configured such that, when the received call is in progress during the open state of the second case, the received call is switchable from the receiver to the bone conduction speaker.
