A speaker is provided to implement a high sound quality and a high power by preventing a bobbin from being changed and increasing a coupled area between a vibration plate and the bobbin. A speaker includes a fixing unit(500), a moving unit(400), a vibration plate(200), and a guide member(800). The fixing unit is coupled to a predetermined position of a base frame(700). The moving unit is moved from the fixing unit by an electromagnetic force. The vibration plate is vibrated with being coupled with the moving unit. The guide member is installed between the moving unit and the vibration unit. The vibration plate has a track shape. The moving unit has a corresponding shape to the vibration plate. The guide member includes an upper member and a lower member. The upper member is coupled to the vibration plate. The lower member is coupled to the upper member and is coupled to the moving unit.
