Zusammenfassung:	PURPOSE: An one-directional oval type speaker for mobile communication terminal is provided to enhance the magnetic force and improve the sound quality by using a two-magnet structure instead of the existing one-magnet structure. CONSTITUTION: A plate(11') is installed at an upper end of an oval type permanent magnet having a center hole in order to form an one-directional oval type speaker of one magnet structure. The permanent magnet is formed with a two-magnet structure including a first permanent magnet(10) and a second permanent magnet(10'). The first and the second permanent magnets are formed with rectangular shapes. The plate is loaded on an upper end of the second magnet. The plate is formed with the rectangular shape. A rectangular hole(11'-1) is formed at a center of the plate.
