Abstract

The utility model relates to a musical instrument relating to a resonance violin family. Two resonance beams are added on the basis of the original structure, and the shape of lining wood is changed into trapezium. The resonance violin family with still purer sonification and even more elegant tone color and tone quality eliminates wolf sound in playing as an original violin eliminates wolf sound so that good sound effect is obtained.

Description

Resonance violin family

The utility model is a kind of musical instrument that relates to new Resonance violin family.

In the prior art, violin family musical instrument, bass bar only is housed, sound wave is transmitted to each position of panel by it, owing to be subjected to the restriction of its structure, cause the vertical and horizontal vibration of qin plate that certain time difference is arranged, this species diversity is reflected in the interior air resonance of qin body also will be subjected to corresponding influence, unbalanced, as to keep away unavoidable " wolf sound " in performance appearance.This is the subject matter that modern violin family musical instrument exists.Be again initial and end lining wood with face, the backboard adhesive surface is bigger and upper and lower equating, the vibration of this counter plate and common toot effect also can produce certain influence.These constructional restrictions have reduced the acoustics of violin family musical instrument.

The purpose of this utility model is to develop a kind of wolf sound that do not have, and tonequality, tone color grace resemble old qin, the better new resonance type violin family of acoustics.

Consider that the transaudient speed of wood grain vertically much larger than horizontal characteristics, tries hard to improve panel transverse vibration speed, so that the time difference of whole front panel vibration dwindles, this is the design's a rationale.New Resonance violin family revolves except that having that head, peg, neck, fingerboard, panel, side plate, backboard, string are total, the member of existing violin such as qin sign indicating number, bass bar, lining wood and sound column family, it also has two resonant beam (1), (2) (seeing accompanying drawing 1).Resonant beam is bonded in the back side of panel, and is vertical with bass bar (3), upper and lower each one.It is to coincide and the slightly crooked batten (seeing accompanying drawing 2) of ratio panels with the panel adhesive surface for a resonant beam, and shape is similar to bass bar, along the grain makes.Suppress just to have produced after being bonded on the panel and give stress.Resonant beam is opposite with the direction that bass bar acts on the power on the panel.Resonant beam is accelerated panel transverse vibration conduction, under the acting in conjunction of bass bar, resonant beam, forms new resonator system, panel vertically, laterally all give stress.Be that panel vibration is stronger so on the one hand, air resonance is strengthened in the corresponding qin body; The mistiming that is the panel ambient vibration on the other hand dwindles greatly, and the qin body is toot balance preferably altogether.This just makes toot the coordination degree altogether between panel and the whole qin body improve greatly.

Initial and end lining wood (4) on the side plate, (5) are changed system into its longitudinal profile and are trapezoidal, it and the adhesive surface ratio of panel and the adhesive surface little (seeing accompanying drawing 3) of backboard.Because the stressing conditions difference of upper and lower two adhesive surfaces of lining wood, what bear with the panel adhesive surface is pressure, does not need excessive adhesive surface, serve as a contrast wooden making in echelon with the panel adhesive surface and dwindles, and has so just enlarged the vibration area of panel, makes to be total to toot also enhancing thereupon.

Neck (6), fingerboard (7) correspondence on its adhesive surface have semi-circular groove (seeing accompanying drawing 4), and mutual bonding back forms hollow tubular.Compare with solid construction, be further improved with regard to the effect that makes the vibration of conduction string like this.

Resonant beam be installed in the nodal point of vibration zero-bit be changed to best, best results.The length of last resonant beam is longer slightly for good than the distance between two f nose end heads, and the length of low-resonance beam is longer slightly for good than the distance between lower end, two f holes.

New Resonance violin family is because vibration changes, and resonance is strengthened, toot coordination altogether, and violin pronunciation is purer, and reflection is sensitive, four string volumes, tonequality high conformity, tone color is graceful more, and resembles old qin, has fundamentally eliminated " wolf sound " in playing.Facts have proved that the large, medium and small violin of this kind structure is played through examination and " wolf sound " all do not occurred, is good for sound.They reflect that feel is good especially; Pronunciation is sensitive, and reaction is fast; Four string tonequality, volume are balanced consistent.

Accompanying drawing 1 is the back side of panel synoptic diagram.

Accompanying drawing 2 is the bonding diagrammatic cross-sections of resonant beam and panel.

Accompanying drawing 3 is that side plate and initial and end serve as a contrast wooden diagrammatic cross-section.

Accompanying drawing 4 is neck, fingerboard fluting synoptic diagram.

Claims

1, a kind of have revolve that head, peg, neck, fingerboard, panel, side plate, backboard, string are total, the violin family of qin sign indicating number, bass bar, lining wood and sound column etc., it is characterized in that it has two resonant beam (1), (2), said resonant beam be bonded in panel the back side, vertical, upper and lower with bass bar (3) each one, initial and end serves as a contrast wood (4), (5) in addition, and it is trapezoidal, little with the adhesive surface of backboard with the adhesive surface ratio of panel that its longitudinal profile is.

2, violin as claimed in claim 1 family is characterized in that said resonant beam, and it is to coincide with the panel adhesive surface and slightly crooked batten.

3, as the said violin of claim 1 family, it is characterized in that neck (6), fingerboard (7), correspondence has half slot on its adhesive surface, and mutual bonding back forms hollow tubular.
