Abstract

The present invention relates to a flat diaphragm and to a planar speaker using same. The flat diaphragm according to the present invention comprises: a base plate made of an epoxy resin containing glass fiber; a metal foil which is attached onto a lower surface of the base plate, and on which a circuit pattern for electrically connecting voice coils is formed; an annular edge unit arranged along an edge of the base plate; and a plurality of conductive suspensions electrically connected to the circuit pattern of the metal foil to transfer electrical signals and prevent excessive vibrations of the base plate.
