A slim type speaker is provided to use a relatively large damper by coupling a damper in a part of a supporting plate protruded toward an outer side of a shortening part of a supporting rim. A frame(110) includes a supporting rim(111) of a track shape and a supporting plate(115) formed in a bottom side of the supporting rim. An entrance groove(112) is formed in a side of a shortening part of the supporting rim. A through hole of a track shape is formed in a central part of the supporting plate. A magnetic circuit part(120) includes a plate, a magnet(123) coupled in a bottom surface of the plate, and a yoke having a standing plate(125a) and a pole. A connecting hole facing the through hole is formed in a central part of the plate and the magnet. A vibration part(130) includes a damper coupled in the supporting plate, a voice coil, and a vibration plate(135). |
