摘要
The present invention relates to a flat-panel speaker, and more particularly, to a flat-panel speaker having a multilayer PCB pattern voice coil film, which enables induced electromotive force to be increased by controlling the impedance of the multilayer voice coil film. The flat panel speaker having the multilayer PCB pattern voice coil film according to the present invention is characterized in that the voice coil comprises: a PCB (printed circuit board) pattern printed thereon and voice coil films stacked in an even number of 4 layers or more. Two layers each of said voice coil films are mutually connected in series, and the serially-connected voice coil films are connected to each other in parallel.
