PURPOSE: A sound reproducing system using a sound pressure is provided to reproduce high sound quality and have a structure suitable to a mass production. CONSTITUTION: A sound pressure generator(20) generates sound pressure. The first center pole yoke(51) include a plurality of sound pressure passing holes. The sound pressure passes through the sound pressure holes. A magnet(30) encloses the first center pole yoke(51). The first plate(50) is arranged between the sound pressure generator(20) and the magnet(30). The second center pole yoke(51) include a plurality of sound pressure passing holes. The sound pressure passes through the sound pressure holes. The second plate(60) encloses the second center pole yoke(61) and is arranged adjacent to the magnet(30). A sound pressure controller(40) is arranged in a predetermined space between the first center pole yoke(51) and the second center pole yoke(61).
