PROBLEM TO BE SOLVED: To provide a mobile communication terminal that enhances the sound informative performance by generating sound in a sufficient sound volume even when the terminal in folded state is kept to any attitude. SOLUTION: Each rear part of upper and lower cases A, B of a foldable mobile phone is provided with first and second sounders 21a, 21b. Further, an opening/closing discrimination function 12a discriminates whether the upper and lower cases A, B are folded or opened on the basis of a sensing output of a sensor 23. A ringer tone output control function 12b allows both the first and second sounders 21a, 21b to output a ringer tone in a folded state or allows either of the first and second sounders 21a, 21b to output a ringer tone in an opened state as its control on the basis of the result of discrimination.
