    Abstract: The present invention relates to a flat panel speaker with which a speaker can be implemented by maximizing the number of coil turns and reduce unnecessary coil lines and weight. The flat panel speaker may include a pair of magnetic bodies with a movable coil plate therebetween, the magnetic bodies being spaced apart from each other, and movable coils patterned and printed in a printed circuit board (PCB) track shape, and laminated in even numbered layers with two or more layers, wherein: the movable coils are patterned and printed on the movable coil plate of each layer as a first coil track and a second coil track; each of the first coil track and the second coil track comprises a horizontal and vertical line coil; the horizontal line coil is formed by connecting a plurality of lines in parallel; and the vertical line coil is formed in a single line.
