Abstract
A stringed instrument such as an electric guitar has a specially designed body structure, which is configured by a body frame, a center block, at least one bridge, a front board, a back board and a back cover. The bridge is arranged between a side portion of the body frame and a side wall of the center block, thus partitioning an interior space of the body frame to provide a vacant space for arranging electrical parts. Because of the provision of the bridge, it is possible to improve rigidity of the body structure. Herein, the vacant space is reduced in size and area, and it is encompassed by the side portion of the body frame, the side wall of the center block and the bridge. The front board is used to completely cover the front side of the body frame. The back board is partially cut out and is used to cover the back side of the body except for the opening area of the vacant space inside of the body frame. The back cover is detachably attached to the back side of the body frame in conformity with a cutout of the back board. Because the back cover has a restricted size and shape for merely covering the opening area of the vacant space in the backside of the body, it is possible to prevent the back cover from easily resonating with sounds produced by plucking the strings of the stringed instrument. Thus, it is possible to improve the sound quality as well as the appearance of the backside of the stringed instrument.
