PURPOSE: A ribbon type speaker which increase the driving force is provided to improve a magnetization direction to a horizontal direction by respectively horizontally arranging a first magnet and a second magnet about a first plate, a second plate, and a third plate. CONSTITUTION: A vibration plate(120) is supported on a supporting frame(110). The supporting frame generates sound pressure through the vibration. A voice coil(130) is connected to a lower side of the vibration plate. The voice coil of an FPCB type transfers vibration to the vibration plate by receiving a voice signal. A first plate(141), a second plate(142), and a third plate(143) are installed in the location of the voice coil. A first magnet is located between the first plate and the second plate. A first magnet is located between the second plate and the third plate.
