PURPOSE: A mobile communication terminal is provided to supply a flat speaker for simultaneously performing a vibration plate role and a signal conversion function by using piezoelectric properties of a high-polymer film, thereby realizing miniaturization and lightness of the mobile communication terminal. CONSTITUTION: A flat speaker(120) is attached to a predetermined part of a terminal(100). The flat speaker(120) is attached to the predetermined part of the terminal(100) by inserting a support(130) into a rear side of an LCD window(110) of the terminal(100). The flat speaker(120) formed with a PVDF(Polyvinylidene Fluoride) piezoelectric film is formed under 1mm in thickness. The piezoelectric film is made of a transparent material, functioning as a speaker when the flat speaker(120) is attached to the rear side of the LCD window(110).
