Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of musical instrument components, in particular to a new type of embedded threaded tuning peg. Background Technique
[0002] At present, there are a wide variety of musical instruments, including the erhu, which is a traditional Chinese bowed string instrument with two strings. The erhu includes a body (including a neck, a sound box, a base, a membrane, and a sound window), a string system (including strings, tuning pegs, a nut, a bridge, and a sound pad), and a bow (including a frog, a stick, and horsehair).
[0003] The existing tuning pegs of the erhu still have the following problems in use: one side is a thick shaft for convenient hand-held turning, and the other side is a thin shaft for threading and winding the strings. When installing the strings of the erhu, first put the small ring at the end of the string (thin string) on the screw under the base of the erhu, then straighten it and put it on the tuning peg. It is fixed on the tuning peg. Insert the string head into the wire hole of the lower tuning peg, pass through and then pull it back and insert it into the head of the erhu. It doesn't need to pass through, just hide the string head. Rotate the tuning peg and wind it clockwise (from the inside out) and tighten it on the tuning peg. The installation holes in the traditional erhu tuning peg and the neck are not easy to fix when stringing, and phenomena such as string slipping and out-of-tune are likely to occur.
