Description

Six strings and 12 string interchangeables are with neck double-purpose guitar

The utility model relates to a kind of multi-usage musical instrument combination.

Present known guitar all has six roots of sensation string, is commonly called as guitar.This six roots of sensation string is from coarse to fine, and six strings are the thickest, and a string is the thinnest, and its pitch roll call generally is decided to be E, A, d, g, b, e respectively ₁A kind of 12 strings (multiple string) guitar is arranged abroad, the YAMAHAAPX-4-12 guitar of producing as Japanese YAMAHA company etc., they are actually " the multiple string double-tone " guitar that derives from the basis of guitar, its string is divided into six roots of sensation master string and the secondary string of the six roots of sensation, is called main 1, main 2 respectively ... main 6 and secondary 1, secondary 2 ... secondary 6.String on main string and the guitar arrange and model identical, by thick to thin; Secondary string then adopts thin string, and wherein secondary 1,2,3,4 strings adopt main 1 string, main 2 strings of secondary 5 strings employing, and secondary 6 strings adopt main 3 strings, and the distance between the secondary string of each root master string and each root is very near, is no more than 2mm, and when manipulating the strings with assurance, the major-minor string is vibration sounding simultaneously.Aspect the accordatura of string, the interval of each root master string string secondary with it is unison or harmonious pure tone journey relation such as octave.Generally can be decided to be E and e or a, A and a, D and d ₁, G and g ₁, b and b, e ₁And e ₁, the sound of two like this twang signal to noise ratio monochords is the horn of plenty harmony more, and when particularly playing chord, acoustics is more outstanding, and that is sharp or blunt clean but it removes but can not play out guitar, and the effect with " granular sensation " is come.At this situation, abroad, there is the people that this good for both sides qin is blended together, make a kind of pair of neck guitar.It has two necks, and two scroll heads are fixed with 12 strings on a neck, be fixed with six roots of sensation string on another neck,, use very inconvenient though solved the problem of a qin double-purpose, and the production cost height, complex process, practicality are not strong.

The purpose of this utility model provides a kind of six strings and 12 string interchangeables with neck double-purpose guitar, to solve under the situation that does not change guitar basic configuration and structure the problem of a qin double-purpose.

The utility model be achieved in that it by scroll head, go up capotasto, neck (attached fingerboard), string, lower chord pillow and major parts such as qin sign indicating number, qin case thereof and form.The profile of its neck, qin case and internal structure are similar to common guitar, but have structurally carried out intensive treatment to a certain degree, can bear the pulling force of 12 strings simultaneously.On scroll head and qin sign indicating number, arranging that respectively 12 are arranged the orderly accurate chord eye of string to draw 12 strings, its cloth string accordatura mode is identical with foregoing 12 strings (multiple string) guitar.And feature of capotasto and lower chord pillow is obvious on it: is cylindrical shape, can under the control of handle on the capotasto or link gear, rotates freely, so the capotasto position at scroll head and qin sign indicating number place is configured to semi-circular recesses so that with circle on lower chord pillow match.On upper and lower capotasto, there are six main chord slots and six sub-chord slots to round respectively.Main chord slot is around upper and lower capotasto the time, and its groove depth is more shallow and consistent, and the transverse section is and includes nettedly with one heart, and the main action degree that is pressed in like this in the main chord slot can not change with the rotation of last lower chord pillow; Sub-chord slot around upper and lower capotasto the time, groove depth from light to dark, shallow by returning to deeply again, its transverse section is cam-like, like this, the secondary string that is pressed in the sub-chord slot will rotate and raises or reduce along with last lower chord pillow.And as long as change the outline line of its " cam ", as adopting constant velocity spiral, off-centre includes circle etc., just can make secondary action degree change the needs that adapt to practical application.Therefore go up lower chord pillow and adopt such structure, can rapidly six strings and two kinds of patterns of 12 strings be exchanged, can understand like this: when the contact point of major and minor string and major and minor groove all is the shallow slot state, major and minor string is normal value apart from the height of fingerboard and panel, like this, 12 major-minor strings can both vibration sounding, and 12 strings (multiple string) guitar that can be used as standard uses; When rotate going up lower chord pillow to the position among wherein the secondary string of the six roots of sensation all is in deep trouth, secondary string drops to minimum point apart from the height of fingerboard and panel, and be attached on the fingerboard, lost the function of vibration sounding, and six roots of sensation master string is owing to go up the main chord slot groove depth unanimity of lower chord pillow when rotating, therefore can continue to keep vibration sounding function, become six string guitars of standard.In order to make the secondary string of the six roots of sensation stop vibration more reliably, also having six system sound brushes can be pressed in the rotation of lower chord pillow on the secondary string of the six roots of sensation of action reduction on the lower chord pillow, and can leave secondary string, thereby guarantee that the playing quality of this guitar under different conditions is unaffected with the rising of secondary string.

Adopt above scheme that following advantage is arranged:

(1) regulates conversion conveniently.Realize the conversion of six strings and two kinds of patterns of 12 strings by rotating mode that lower chord pillow rotates, very fast, can accomplish to finish in 1 second, make a first melody become possibility with two kinds of patterns performances.

(2) simple in structure, can be basically under the situation that does not change guitar profile and structure, with 12 string guitars and six string guitars in the advantage on the audio comprehensively on a guitar.

(3) applied widely, all applicable on various forms of guitars such as wooden guitar, electric guitar, folk rhyme guitar, classical guitar.

(4) expressive force and the appeal of guitar have been enriched, for guitar is played and the manufacturing field has increased a kind of new art mode.
