Abstract

The present invention relates to a flat-type speaker, and more specifically, to a flat-type speaker in which a plurality of magnetic circuits are horizontally connected in serial or in parallel such that one speaker is formed. According to the present invention, a flat-type speaker in which a plurality of magnetic circuits are horizontally connected is constituted by: a horizontal connection structure in which two or more pairs of independent magnetic bodies having different polarities are equipped; on said two or more magnetic bodies, enabling two or more voice coil plates, on which voice coils are printed, to be vertically arranged between the respective magnetic bodies in a horizontal direction; enabling the stream of currents of said two or more voice coil plates to maintain the same direction; allowing two or more thin film-shaped vibration-lead plates to be positioned on the upper end of said two or more voice coil plates such that the plates are electrically separated from each other; and allowing said voice coils and said two or more vibration-lead plates to be electrically connected with each other.
