Audio output device, its alarm output control method, and its control program
First Claim
1. An audio output device provided with an electro-acoustic transducer that converts an electrical signal to a sound wave and radiates thus generated sound wave, comprising:
- a sound controller configured to control the electro-acoustic transducer under any one sound mode of a small volume sound mode that outputs a sound with volume which is smaller than a predetermined value so as to hear a sound by setting the user'"'"'s ear in close proximity to the electro-acoustic transducer, or a large volume sound mode that outputs a sound with volume which is larger than a predetermined value so as to hear a sound by setting the user'"'"'s ear away from the electro-acoustic transducer; and
an alarm output unit configured to, before radiating a sound wave from the electro-acoustic transducer under the large volume sound mode, output an alarm to call user'"'"'s attention so as to protect the user'"'"'s ear.

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 (1) at the speaking position and listens to a message output from an audio output unit (8), a control unit (17) makes a vibrator (27) generate a vibration as an alarm to call user'"'"'s attention. At the timing when the user has sufficiently separated the mobile telephone (1) from his/her ear, the control unit (17) makes the audio output unit (8) 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.

12. An alarm output control method in an audio output device provided with an electro-acoustic transducer that converts an electrical signal to a sound wave and radiates thus generated sound wave, comprising:
-
a sound control step of controlling the electro-acoustic transducer under any one sound mode of a small volume sound mode that outputs a sound with volume which is smaller than a predetermined value so as to hear a sound by setting the user'"'"'s ear in close proximity to the electro-acoustic transducer, or a large volume sound mode that outputs a sound with volume which is larger than a predetermined value so as to hear a sound by setting the user'"'"'s ear away from the electro-acoustic transducer; and an alarm output step of, before radiating a sound wave from the electro-acoustic transducer under the large volume sound mode, outputting an alarm to call user'"'"'s attention so as to protect the user'"'"'s ear. - View Dependent Claims (13, 14, 15, 16, 17)
