Abstract

The utility model provides a mobile tonal modification clamp with the type II for a guitar. The utility model is characterized in that the tonal modification clamp with the type II comprises a seat body, a contacting rubber pad which is arranged on the seat body and is used for supporting a guitar neck, and a left and a right upper seat body which can be connected with the seat body; a longitudinal spring is arranged in the first flute of the left and the right upper seat body, and the longitudinal spring is connected with both ends of a guide block with a projecting station; the lower plane of the guide block is connected with a rubber pressing block which can be used for pressing strings, and a cross spring is arranged in the second flute of the left upper seat body; one end of a slide block with the projecting station is connected with the cross spring, and is formed a frictional contact with the guide block with the projecting station; the upper part of the right upper seat body is provided with a lock catch button with a built-in spring, the lock catch button is used for the decline locking of the slide block, and the built-in spring is used for making the lock catch button be returned. When the tonal modification clamp with the type II needs to be moved, the lock catch button can be pressed, can make the slide block be returned and can make the rubber pressing block be relaxed; after the tonal modification clamp with the type II is moved to the needed position, the slide block can be pushed by one hand, the guide block can drive the rubber pressing block to descend and the strings can be pressed tightly, and the tonal modification function can be finished. The utility model can accomplish the free tonal modification dispensing with stopping the performance, and the music can be coherent.

Description

The portable folder II 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 characterized in that referring to Fig. 1-Fig. 5: it includes pedestal 1, and the contact rubber cushion 2 that is used to support neck that is provided with on the pedestal 1 is connected upper right pedestal 3 and upper left pedestal 4 on pedestal 1 left and right two end faces; Wherein upper right pedestal 3 and upper left pedestal 4 are respectively equipped with longitudinal spring 5 near in first groove of pedestal 1, the two ends that have the guide block 6 of convex are connected with making its longitudinal spring that resets 5, the lower plane of guide block 6 is connected with the rubber briquetting 7 that compresses string, be provided with crossed strip 9 in second groove of the close pedestal 1 of upper left pedestal 4, an end that has the slide block 8 of convex is connected with crossed strip 9, and form rubbing contact with the guide block 6 that has convex, the end face of upper right pedestal 3 is provided with the snap close of built-in spring 11 and turns round 10, snap close is turned round 10 and is used for slide block 8 locking of gliding, and built-in spring 11 is used for making snap close to turn round 10 resetting.

Wherein said upper right pedestal 3 upper left pedestal 4 both sides transverse sides are connecting the casing cover 12 that its relative position is fixing respectively.

Wherein said pedestal 1 and upper right pedestal 3 and upper left pedestal 4 are connected by screw, and casing cover 12 also is to adopt screw to be connected with upper right pedestal 3 upper left pedestals 4.

For difference custom that satisfies the player and the needs that the folder that modifies tone is controlled and used, can change upper right pedestal 3, upper left pedestal 4 that is connected with pedestal 1 and the left and right directions position of going up each connected components thereof, referring to accompanying drawing 4.

Use-pattern of the present utility model is: when needs are mobile, press snap close with hand and turn round 10 slide block 8 is resetted, thereby rubber briquetting 7 is loosened.To modify tone to press from both sides with hand then and move to the desired position.And then with singlehanded sliding piece 8, make guide block 6 drive 7 declines of rubber briquetting and compress string, finish the modified tone function.

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.
