Abstract
It is possible to surely protect the user's ear from a sudden large volume and enable the user to surely and clearly hear a sound as information to be alarmed. In case an incoming call signal is received when the user holds a mobile telephone () at the speaking position and listens to a message output from an audio output unit (), a control unit () makes a vibrator () generate a vibration as an alarm to call user's attention. At the timing when the user has sufficiently separated the mobile telephone () from his/her ear, the control unit () makes the audio output unit () output a ringtone of large volume. Thus, it is possible to surely protect the user's ear from a sudden large volume. Even when a music composition to notify the receipt of incoming call signal is used as a ringtone, the user can surely and clearly hear the sound as information to be alarmed.
