PURPOSE: A two-channel integration speaker is provided to be capable of making a mobile communication terminal light and thin by adding a function of a receiver to a speaker. CONSTITUTION: A frame(110) is installed in a main body of a mobile communication terminal and has an opened upper surface. A terminal plate(140) is provided at the outside of the frame and has the first to third copper plates. A magnet(121) is spaced apart from an inner surface of a cap part and is installed at the cap part. A pole piece(125) is spaced apart from an inner surface of the cap part and is installed on the magnet. A vibration plate(130) is installed at the frame so as to cover an upper surface of the frame. A voice coil(133) is installed at the vibration plate so as to be placed between the frame and the pole piece and is connected to the second and third copper plates. A resistor is connected to the first and third copper plates and is connected in series to the voice coil.
