1. A magnetic circuit for a slim type speaker, comprising:

  • a perpendicular-magnetized permanent magnet;

    a plate that is formed of a paramagnetic material and is attached to a surface of the perpendicular-magnetized permanent magnet; and

    horizontal-magnetized permanent magnets that are arranged at opposite sides of the perpendicular-magnetized permanent magnet and are spaced apart from the perpendicular-magnetized permanent magnet by a predetermined interval,wherein the perpendicular-magnetized permanent magnet and the horizontal-magnetized permanent magnets interact with each other to form a uniform magnetic field.
