Abstract
The invention relates to series of Qinhu nuts, which is characterized in that hard maple is selected as raw material to make into block body of 'axe' shape, the upper top face of the block body is equipped with two open slots which is used to support strings, two voice holes on the upper portion of the block body are respectively communicated with the lower circular arc long through hole, the bottom of the block body is equipped with a long circular through hole with 'arch' opening which is connected with a resonating plate. The invention has advantages that the vibration and conduction are extremely good, impurity is filtered to make the voice purer, the shape and the structure are more suitable for the happening and vibrating of the panel musical instruments, the two voice holes loose the voice and soften tone quality, the long through hole can filter noise and the bottom is equipped with a semi-circle hole with opening connecting with the resonating plate, which is more favorable for the advantages and effects of the conduction and happening of the voice.
Description
Technical field
The present invention relates to a kind of series Qinhu bridge, belong to bowed instrument accessory field.
Background technology
The Qin is the novel bowed instrument of being reformed on traditional urheen type system recklessly.Per four of series Qinhu is one group, name high Hu respectively into the Qin, Qin's urheen, Hu and the Da Hu of the Qin in the Qin, with corresponding high pitch, alto, middle pitch and bass part, range is contained three octaves, existing bridge is used the hollow horse of the Atria face boring eye building sky of bamboo making, open two breach again on the nightstool top, another kind is made bridge shape to small bamboo block the empty horse of bridge, and effect is quite a lot of than hollow horse is general for the empty horse of bridge, and the bridge of ware string Chinese fiddle has the groove breach, all there is not concrete structure, its fault is not filter the noise hole, is not hard material, occurs the vibration between bridge and sounding board easily, cooperate not closely, produce and to beat or slippage.
Summary of the invention
Purpose of the present invention provides a kind of light weight rigidity big indeformable series Qinhu bridge for the shortcoming that overcomes above-mentioned prior art existence with deficiency just, thereby make not vibrating between Qin's Hu sounding board and bridge, cooperate closely, do not produce and beat or slippage, play more bright and glittering.
The objective of the invention is to realize by following technical proposal:
Series Qinhu bridge, it selects for use hard maple wood to make the block of axe-shape for material, the open slot 1 that two frame strings are arranged on the plane, top on the block, two sound holes 2 are arranged on block top, two sound holes communicate with the following circular arc long through-hole 3 that tilts laterally respectively, and the oval through hole 4 of the opening arch of joining with sounding board is arranged at the block bottom.
The open slot of described two frame strings distance be 5.5mm～6.0mm, and described two sound bore dias are arranged on block top is 1.2mm～2.0mm, two sound pitch of holes 5mm～7mm, highly 17mm～26mm.
Series Qinhu bridge of the present invention selects for use hard maple wood to be material, Chinese name: white ox maple, another name: white ox, external title: the Hard Maple place of production: Canada is commonly called as: add maple, it has clean mark easily debates, and drying shrinkage is slow, but shrinkage factor is bigger, facts have proved that the series Qinhu bridge that it is made makes Qin's sound quality, performance recklessly be optimized and distil.
Series Qinhu has carried out acoustics through Acoustical Inst., Chinese Academy of Sciences and has held property testing, wherein to bridge test of the present invention and test result is:
The bridge of unlike material is to the measurement of the influence of tonequality, the rigidity difference that the material difference of bridge causes, can influence bridge the vibration of string is directed to performance on the sounding board, show as the function of a wave filter, perfect rigidity can not bring error by bridge, and the different bridge of density can cause each frequency sound generating amplitude fading and phase deviation in the music.Respectively the unlike material bridge is drawn duplicate sound, compare the frequency spectrum difference of sound of musical instrument that microphone is surveyed then, just can reflect the influence of bridge material.
Bridge is the hard wooden unit that is adhesive on the sounding board, and the conduct vibrations of string to sounding board, and is produced general frequency, has on the bridge with two apertures of curved slot laterally to filter noises, is rectangular arch.
Bridge requires light weight, and rigidity is big, and is indeformable, cooperates with sounding board closely, the vibration between bridge and sounding board can not occur, and promptly bridge can not be beated or slippage by the off-resonance plate.
White ox (hard maple wood) bridge can increase harmonics quantity and amplitude
To empty-chord sound, the high frequency harmonics is the strongest when using white ox bridge, and overtone is abundant.And the humorous frequency spectrum of low frequency is the strongest when using the red sandalwood bridge, but the harmonics amplitude is low, and overtone weakens to some extent.Sounding effect when using red acid branch bridge is between the two.
Internal string sound d2, the harmonics amplitude is the strongest when using white ox bridge, and overtone is abundant.And the humorous spectrum of low frequency is the strongest when using the red sandalwood bridge, but the harmonics amplitude is low, and overtone weakens to some extent.Sounding effect when using the red acid branch is between the two.Internal string sound g1, the high frequency harmonics is basic identical when using 3 kinds of bridges.And the humorous spectrum of low frequency is the strongest when using the red sandalwood bridge, the loudness height.Sounding effect when using the red acid branch is between the two.
External empty-chord sound, the high frequency harmonics is the strongest when using white ox bridge, and overtone is abundant.And low frequency harmonics line spectrum difference is little when using 3 kinds of bridges.Sounding effect when using red acid branch bridge is between the two.
To exterior string sound a2, the high frequency harmonics is the strongest when using white ox bridge, and overtone is abundant.And the humorous spectrum of low frequency is the strongest when using the red sandalwood bridge, but the harmonics amplitude is low, and overtone weakens to some extent.Sounding effect when using the red acid branch is between the two.
Owing to take technique scheme to make the technology of the present invention compared with the prior art have following advantage and effect:
A) select for use the musical instrument of hard maple wood material and wooden structures can extraordinary conduction vibration, impurity screening makes sound purer,
B) She Ji shape and structure are more suitable for the generation and the vibration of plate face musical instrument,
C) to have played sound lax two sound holes, the effect of soft and graceful tone color, and microscler through hole can filter noise,
D) the open semi circular hole that joins with sounding board is arranged at the bottom, is more conducive to initiating and take place of sound.

Embodiment
Series Qinhu bridge, by Fig. 1, shown in 2, bridge is to be adhesive in middle part on the sounding board, pressure by inside and outside string makes it fixing, it selects for use hard maple wood to make the block of axe-shape for material, the open slot 1 that two frame strings are arranged on the plane, top on the block, two sound holes 2 are arranged on block top, two sound holes have been played sound and have been relaxed, the effect of soft and graceful tone color, two sound holes communicate with the downward-sloping circular arc long through-hole 3 of both sides respectively, and microscler through hole can filter noise, and the block bottom has the oval through hole 4 of the opening arch of joining with sounding board to be more conducive to initiating of sound and takes place.
