<p>The present invention relates to an electric gayageum which comprises a main upper plate which has a needle which has an upper surface which is convex in a width direction and is combined with one end of the upper surface in a length direction, and a bridge which is stepped in the other part of the upper surface in the length direction; a stop which is arranged between the needle and the bridge; a string which has both ends fixed to the needle and the bridge and is supported by the stop; a main lower plate which has a lower surface which is concave in the width direction and has a reinforcement rib protruding in the length direction of the lower surface and is combined with the main upper surface. A reinforcement framework which is formed in an inner space formed by the main upper plate and the main lower plate and is arranged in the length direction of the main upper plate and the main lower plate. Thereby, deformation such as warpage and distortion according to the length direction can be prevented and weigh lighting can be achieved.</p> |
