PURPOSE: A slim type speaker is provided to widely form width of a shortening direction by widely forming an interval between external diameter of a vibration plate and inside diameter. CONSTITUTION: A frame(110) is formed into selected one shape among ellipse shape, racetrack shape, or rectangular shape. A magnetic circuit part(120) generating magnetic force is combined in the lower-part of the frame. A sound generation part(130) reproducing sound is installed in the upper surface of the frame. The magnetic circuit part comprises a yoke(121), a bottom plate(123), and a magnet(125) and a cover plate(127). The sound generation part comprises a voice coil(131), a cap(133), and an edge(135) and a vibration plate(137). |
