Abstract

The utility model provides a mobile tonal modification clamp of the type I for a guitar. The utility model is characterized in that the tonal modification clamp comprises an upper rod 1 sheathed with a rubber 4 which is used for contacting strings and a guitar neck finger plate, a lower rod 6 sheathed with an abnormity rubber 7 which is contacted and matched with the guitar neck, a draw rod 8 which is fixed in tow with the lower rod, and springs 9 which can be connected with the end parts of both sides of the upper rod and the lower rod and can be used for controlling and pressing the guitar string tensile force arranged between the upper rod and the lower rod. While in use, the draw rod 8 can be pulled by one hand, the springs 9 can be stretched, and the draw rod moved by hands can drive the upper rod 1 to move the needed moving position from some one grid of the guitar neck; after the draw rod is loosened, the upper rod can press the strings depending on the tensile force of the springs, and the tonal modification can be finished. The utility model can make the free movement on the guitar neck be attained, and the purpose of the tonal modification oparated by one hand can be attained; when the ending tone of the music needs to be modified, the free tonal modification can be attained dispensing with stopping the performance, and the music can be coherent. The color can be modified through different melodies, and the expressive force of the music can be reinforced.

Description

The portable folder I type that modifies tone of a kind of guitar

Technical field:

The utility model belongs to a kind of guitar folder that modifies tone, relate to six roots of sensation string, as guitar class plucked instrument.

Background technology:

Usually known to, guitar is a kind of plucked instrument, and six roots of sensation string is arranged usually.The hand string that keeps left, the right hand is played sounding.Left hand changes the position of pressing string, can change pitch.Bonding jumper on the neck panel is called product.Because guitar is the twelve-tone equal temperament musical instrument, adjacent two lattice i.e. phase difference of half sound between two product.During as empty string, play, then be expressed as C and transfer by C tuning rank.Be clipped in first lattice if at this moment will modify tone, play by C tuning rank equally, then be expressed as ^#The C accent (or ^bD transfers).If modified tone is folded up at second lattice, play by C tuning rank, then be expressed as D and transfer; If then being expressed as A with the performance of G tuning rank transfers.The modified tone principle that Here it is modifies tone and press from both sides.

The purport of pressing from both sides that modifies tone is to simplify chord, makes the player give the bigger expressive space of player bigger energy performance aspect the musical.In the guitar of multiple styles such as allusion, folk rhyme is played, application is arranged all.The basic comprising unit is the chord fingering in guitar performance fingering.Chord is divided into two kinds of open type chord and enclosed chords.Wherein the enclosed chord mostly is single finger and will pins many strings, and its tone is raise, and this method of playing is called horizontal in (be called barye and play method in classical guitar).What in most cases serve as this effect is left index finger, the folder that modifies tone can be pinned many strings of same product simultaneously, can replace the effect of forefinger in the enclosed chord, so just can save player's a finger, this means that the performance of music will have bigger space and possibility.

At present the guitar that the uses folder that modifies tone is all fixed, by a rubber bar clinching and tightly guitar on to reach the effect of pressing string.When playing music need modify tone, then need to stop to play, take off the folder that modifies tone, again it is moved to desired location, buckle well the purpose that just can reach modified tone again.But the continuity of melody has been subjected to destruction, has lost the complete performance of original music.

Summary of the invention:

The purpose of this utility model is to overcome above deficiency, designs the portable folder that modifies tone of a kind of guitar, and this modified tone folder can move freely on neck, and one-handed performance just can reach the purpose of modified tone.

The technical solution of the utility model is referring to Fig. 1-Fig. 4, it is characterized in that: it comprises the upper boom 1 that is with the rubber 4 that is used for contacting string and neck fingerboard part, be with the lower beam 6 that partly contacts the special-shaped rubber 7 that matches with neck, with the pull bar 8 that lower beam 6 is fixed together, that upper boom 1 and lower beam 6 both side ends connect, be used to control the spring 9 that presses the guitar string tension force that places between upper boom 1 and the lower beam 6.

Wherein said upper boom 1 and lower beam 6 both ends are equipped with catch 2 and active blade 3, and catch 2 and active blade 3 are provided with the annulus 5 that is used for fixing spring 9; Wherein catch 2 is fixed on the same side of upper boom 1 and lower beam 6, and another side adopts known technology to connect dismountable active blade 3.

Wherein said active blade 3 is by being threaded in upper boom 1 and lower beam 6 both side ends.

Use-pattern of the present utility model is: when one hand is held pull bar 8, exert oneself a little, spring 9 is stretched, and drops pull bar 8 with hand and drives upper booms 1 and move to the position that will move by a certain lattice of neck.Releasing lever 8 relies on the tension force of spring, and upper boom 1 just can press string, reaches the purpose of modified tone.

Design proposal of the present utility model has reached on neck and has moved freely, and the purpose that one-handed performance just can modify tone when the phrase ending needs to modify tone, need not stop just to play and can freely modify tone, and melody is linked up.By different tune mode colors, strengthened the expressive force of melody.

Embodiment:

1-accompanying drawing 4 adopts conventional machining technique to carry out design and installation in conjunction with the accompanying drawings.According to Fig. 1, upper boom 1 both sides are connected with catch 2 and active blade 3, be with ebonite skin 4 on the upper boom 1, be connected with annulus 5 on catch 2 and the active blade 3, be with obform body rubber 7 on the lower beam 6, lower beam 6 both sides are connected with catch 2 and active blade 3, are connected with annulus 5 on catch 2 and the active blade 3, lower beam 6 welds together with pull bar 8, is connected with spring 9 between the homonymy annulus 5.All assembly parts of the utility model all adopt universal accessories to finish.
