Violin tailpiece with reciprocating lengthening and wide-arc involute groove string hooks

Abstract

The invention provides a violin tailpiece with reciprocating lengthening and wide-arc involute groove string hooks in the technical field of musical instruments, and the violin tailpiece comprises: amain tailpiece which is provided with a chute at the central part, four string hook through grooves at the head part, and a main blind hole and two tail rope through holes at the bottom part, whereina screw hole is formed between each string hook through groove and the sliding groove; an auxiliary tailpiece which is arranged in the sliding groove, wherein an ejector rod positioning hole and an auxiliary blind hole are formed in the two ends of the auxiliary tailpiece respectively. an ejector is arranged, one end of the ejector rod abuts against the auxiliary blind hole, the other end of the ejector rod abuts against the main blind hole, and reciprocating relay lengthening of the main tailpiece and the auxiliary tailpiece is formed; four wide-arc involute groove string hooks which are provided with involute grooves and wide arc surfaces and are arranged in the string hook through grooves, wherein the involute grooves do not damage a string ball head string hook, and the wide arc surfaces are used for finely adjusting noise reduction intonation of the wide cambered surface and the inner wall of the rolling string hook through groove. The invention has the advantages that: intonationshift, bridge bending and surface damage caused by environmental humidity change are greatly reduced, the damage of string cores and ball head winding wires is avoided, and the noise is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of musical instruments, in particular to a violin tailpiece with reciprocating lengthening and wide-arc gradual groove hooks. Background technique [0002] The tailpiece of the violin is a necessary part of the violin, taking the cello 100' as an example, such as Figure 15 to Figure 18 As shown, it includes tailpiece 1', fine-tuning hook 2', screw 3', tail rope 4', string ball head 5', secondary string 6' (the section from string ball head 5' to saddle 8') , Main string 7' (short 8' to saddle 13'), saddle 8', saddle top 9' (piano top below saddle 8'), saddle top 10' (saddle 8' 'Above the piano surface), body 11', fingerboard 12', nut 13', string tail 14', peg 15', tail nut 16', tail post button cover 17' and tail rope fixing screw 18' . [0003] The tailpiece 1' is set under the piano body 11', the tail is pulled by the tail rope 4' and the tail rope fixing screw 18', and then fixed on the tail column but...

Problems solved by technology

[0008] 4. The traditional fine-tuning string hook 2' adopts the following three forms: ①. The curved surface string hook as thin as a knife edge (in order to connect with the universal keyhole type string hole), which is easy to vibrate and generate noise, which is then passed to the The hard tailpiece will amplify the noise; ②, a steel wire passes through four string hooks at the same time, and the noise generated by the vibration of the string hook and the steel wire is transmitted to the hard tailpiece, which will amplify the noise; ③, directly Installing the whole trimmer on the keyhole-type string hole is easy to produce noise and uncoordinated sound

[0009] 5. The traditional tailpiece 1' is mainly hard and thin. Hard and solid will affect the sensitivity, so it is made thin to reduce weight. Its upper end pulls the fine-tuning hook 2' and the auxiliary string 6' to the bridge , the lower end is pulled by the tail rope 4' and the tail rope fixing screw 18', and the whole tailpiece 1' is suspended in a suspended state, forming a noise amplifier, that is, a noise vibration plate

[0010] 6. The front and rear widths of the fine-tuning hook grooves of the traditional fine-tuning hook 2' are the same. In order to simultaneously supply four strings with different thicknesses, the grooves are very wide, causing the string ball head 5' to be skewed. The string ball head 5' is not stuck, it is very easy to damage the winding wire and string core of the string ball head 5', especially the nylon string core
