Description
Technical Field
[0001] The utility model relates to the technical field of musical instruments, and particularly relates to a durable body structure of a dulcimer. Background Art
[0002] The existing dulcimer generally consists of a body, multiple rows of bridge, multiple string nails, multiple tuning pegs and multiple strings. The body includes a resonance box, which is composed of a panel, a front side plate, a left side plate, a rear side plate, a right side plate and a bottom plate; each row of bridge is installed on the panel, each string nail is installed at the left end of the resonance box, each tuning peg is installed at the right end of the resonance box, and both ends of each string are respectively connected to the corresponding tuning peg and string nail. The bridge is used to support the strings. The above resonance box (except the panel) is made by hollowing out a complete wooden board in the middle, and the grain direction of the wooden board is the left-right direction. When each string is wound around the corresponding tuning peg and string nail in sequence, a huge tensile force will be generated on each string. The huge tensile force of each string will act on the left and right ends of the resonance box. Since the grain of the left and right ends of the resonance box is in the left-right direction, the left and right ends of the resonance box cannot withstand the huge tensile force generated by each string for a long time, which easily leads to the loosening of the tuning peg and string nail, and even causes cracks in the resonance box, shortening the service life.
