Abstract

The utility model discloses a kind of high Hu being easy to vibrato, beautifying tone color, it is provided with qin bar 1 on qin cylinder 6, is provided with qin axle 2 on the top of qin bar 1, is connected to string 5 between the qin holder 8 of qin axle 2 and qin cylinder bottom; Described qin bar 1 is provided with very heavy 4, and it is also provided with vibration very heavy 3 on qin bar 1; Described vibration very heavy 3 be on qin bar switching have withhold string withhold bar 11, described in withhold between bar 11 and qin bar 1 and be provided with the drop-down spring 13 withholding bar.By height recklessly on to arrange vibration very heavy, making the feel of player when playing become more lax, so just significantly reducing the difficulty of vibrato, not only can kneadding easily, easily can also realize the vibrato of normal tumbling and nip drum convolution.Due to vibrate very heavy in be provided with spring, spring can vibrate with the vibration of string, has superposed new vibration when the fundamental frequency of string is constant, and this just makes its tone color more soft and graceful, and especially when empty string is played, the improvement of tone color is more outstanding.

Description

Be easy to vibrato, beautify the recklessly high of tone color

Technical field

The utility model relates to a kind of national musical instruments, especially a kind of high Hu being easy to vibrato, beautifying tone color.

Background technology

Height is high pitch bowed instrument recklessly, its shape, structure, performance bowing and skill and performance symbol used etc., and all substantially similar with urheen, qin cylinder (resonant tank) is more smaller than urheen, and the part that conventional two legs clip qin cylinder is played.High structure is recklessly provided with qin bar on qin cylinder, and be provided with qin axle on the top of qin bar, be connected to string between the qin holder of qin axle and qin cylinder bottom, qin skin is provided with bridge; Qin bar is also provided with string is play fixing and chord of contact effect very heavy (also known as a thousand pieces of gold).High recklessly when playing, utilize the friction between bow and string to drive string vibration, string by the vibration of bridge excitation qin skin, then is empathized in qin cylinder, thus produces sound.

The important bowed instrument of part in Gao Hushi traditional instruments orchestra is again solo instrument simultaneously.In band, high recklessly by actual pitch note spectrum, tune up more high-purity than urheen five degree or pure four degree, namely tune up as a (1), e (2) or g (1), d (2).Conventional range is a1 (g1) to b3 (a3) sound, the sound of more than b3 (a3), the distribution of performance middle finger position and two-stringed Chinese fiddle are seemingly, in conventional range scope, its tone color is bright and clear, limpid, be suitable for playing grace, lyric and beautiful, active tune, and often and urheen form octave and assist and play.Thus, vibrato skill seems particularly important.Existing high Hu Yizhi uses traditional rope bundle formula (or gold belongs to Hook formula) very heavy, from string vibration frequency formula (I),

$f=\frac{n}{2l}\sqrt{\frac{T}{\mathrm{\ρ}}}---\left(I\right)$

High l, ρ recklessly of reserving tune are certain, are mainly derived from the pressure (changing tension force T) to string and point the rolling of tripe on string (to change l) in vibrato to the change of frequency.People often feel that when vibrato its string is very hard.Namely when imposing vibrato skill, do not impose enough pressure, string distortion or bending very little, the wave amplitude caused is inadequate.Particularly beginner, the amplitude of vibrato is more difficult to ensure.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of high Hu being easy to vibrato, beautifying tone color more easily realizing tumbling.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: it is provided with qin bar on qin cylinder, is provided with qin axle on the top of qin bar, is connected to string between the qin holder of qin axle and qin cylinder bottom; Described qin bar is provided with very heavy, and it is very heavy that it is also provided with vibration on qin bar; Described vibration is very heavy be on qin bar switching have withhold string withhold bar, described in withhold between bar and qin bar and be provided with the drop-down spring withholding bar.

Described in the utility modelly very heavyly move 3-8cm from traditional very heavy position, below very heavy after the very heavy chord of contact point of described vibration is positioned at and moves.

Qin bar described in the utility model has two to withhold bar by fixed mount switching, and two lower ends of withholding bar are provided with that two to be withheld bar affixed and withhold the depression bar of string.One end of described fixed mount is enclose the fixed part of hoop on qin bar, and described fixed part is provided with the adjusting screw(rod) regulating its degree of tightness; The other end of described fixed mount is two poles of stretching out from fixed part, and bar switching, through the drift bolt having connection two pole, is withheld on drift bolt for described two in the front end of pole.Described drift bolt is socketed with and withholds sleeve pipe between bar two.Withhold bar and be drawbar structure for described two.Described spring is connected to the middle part or middle and lower part of withholding bar.Described depression bar is provided with the groove adapting to string.

The spring regulating device of adjustable springs degree of tightness is provided with between qin bar described in the utility model and spring.Described spring regulating device is the adjustable plate that cover has U-shaped on qin bar, adjustable plate runs through and has threaded rod; One end linking springs of described threaded rod, the other end is supporting setting nut.

The beneficial effect adopting technique scheme to produce is: the utility model is very heavy by arranging vibration on height Hu, originally fixing very heavy suitably on move, the feel of player when playing is made to become more lax, so just the difficulty of vibrato is significantly reduced, not only can kneadding easily, easily can also realize the vibrato of normal tumbling and nip drum convolution.Due to vibrate very heavy in be provided with spring, spring can vibrate with the vibration of string, and namely the utility model has superposed new vibration when the fundamental frequency of string is constant, and this just makes its tone color more soft and graceful, and especially when empty string is played, the improvement of tone color is more outstanding.

Very heavy bar of withholding is vibrated when adopting drawing and pulling type structure in the utility model, player can withhold the length of bar according to the hand-type size adjustment of oneself, change the very heavy chord of contact position of vibration, all can be convenient and practical to juvenile, adult etc., and to traditional playing technique and method without any change.

When the utility model adopts spring regulating device, player can the degree of tightness of regulating spring as required, to realize the very heavy good chord of contact accordatura of this vibration, is applicable to different performance situations to make the utility model.
