Abstract
The utility model relates to a composite side board for a resonance box of a fiddle type stringed musical instrument. The utility model is characterized in that the inner of a side board made of maple which is sawn in a radial direction is added with a bamboo spring flake with the grain direction of 90 DEG on the premise that the shape and manufacture and the outer appearance of an original musical instrument are reserved, bamboo spring is taken from the inner wall layer of Nan bamboo, and the constant value of the acoustic radiation of the high-density rigid surface is very high; in addition, the vibration transmitting speed of the longitudinal grain is 6 times as that of the transverse grain, the originally neglected acoustic function as a musical instrument of the side board is fully activated, and the acoustic quality of the musical instrument is greatly enhanced (namely the level of products is enhanced). The utility model has the advantages of wide range of application, and can be used for the manufacture of side boards of various resonance boxes (cylinders) for musical instruments equally with visible effect.
Description
Technical field:
The utility model is the side plate improvement of violin class stringed instrument resonator.
Background technology:
On western musical instrument and Chinese Musical Instruments structure, pulse as tight as a bowstring musical instrument and plucked instrument (general designation stringed musical instrument), generally form by scroll head, neck (bar) and body, body promptly is the resonance system of stringed musical instrument, form resonant tank by panel, backboard and side plate (qin frame), or epithelium and tube plate composition resonance tube.Stringed musical instrument all is the acoustic energy diffusion of strengthening the string vibration by resonance system, increases volume, promptly produces " sympathetic response ".Because stringed instrument resonator (tube) can be given prominence to some frequency range acoustic energy, not only can enlarge volume, and can change instrument tamber.Therefore, the acoustical behavior of stringed instrument resonator (tube) is most important to the influence of musical instrument tonequality.As the resonant tank of violin, panel adopts density little, light weight, and the fir class quarter sawing timber that elastic modulus is high is made, and backboard and side plate (qin frame) then adopt the higher harder quarter sawing maple of sound radiation constant value to make.Tradition violin manufacture craft, the material of only paying attention to panel, backboard select and instrumental acoustics technology such as thickness distribution on, and the instrumental acoustics function of side plate is ignored, only require by uniform thickness (violin 1.2mm, violoncello 1.8mm) in mould, makes the qin frame after the quarter sawing rift grain maple thin plate curved, compose the violin resonant tank with panel, backboard again.From the instrumental acoustics angle analysis, side plate (qin frame) not only has been to connect the effect that panel, backboard form resonant tank, and the biography of side plate (the same with the sound column effect) harmony radiation effects that shakes is also very important aspect acoustical behavior, should be not out in the cold.The acoustic speed of wood vertical texture of (bamboo) material fiber pattern and cross grain differs 5 times more than.Therefore, if the grain direction of the wooden side plate of traditional quarter sawing is turn 90 degrees, it passes the vibration velocity degree can accelerate greatly, and this more meets the scientific law of instrumental acoustics.But individual layer quarter sawing maple thin plate is easily lost when crooked as making vertical texture into, so just impossible bending forming, if with former maple plate attenuate, inside stick on again a layer texture be 90 the degree materials become the compositeness side plate, can keep traditional appearance and thickness, also easy hot pressing bending forming can be accelerated to pass the vibration velocity degree, and the function of side plate in the musical instrument sympathetic response given full play to.
Summary of the invention:
The utility model purpose is keeping under violin kind musical instrument resonant tank tradition shape system characteristics and the manufacture craft prerequisite, only with the log side plate, to improve the compound side plate of the violin class stringed instrument resonator that forms for the vertical gummed with the bamboo wood texture of a kind of timber.
Technical solutions of the utility model:
With former individual layer quarter sawing maple side plate 2 attenuates, stick on the bamboo spring thin slice 3 that a layer texture is 90 degree orthogonals more inside.
The used bamboo spring material of the utility model is to be taken from by the processing of bamboo inner wall layer, and its quality is hard, and the density height has high sound radiation constant value.Bamboo spring thin slice texture is 90 degree hot-press gluings at maple side plate nexine, both kept former musical instrument shape system outward appearance, can accelerate to pass the vibration velocity degree again, its highdensity rigid surface (loud radiation constant value), also can accelerate the acoustic energy diffusion, strengthen homophonic energy, can promote the acoustic quality of musical instrument significantly, i.e. product specification.
The utility model is applied widely, and can be used for the making of multiple rubbing down (tube) side plate all has remarkable result.
Description of drawings:
Fig. 1 violin resonant tank structural representation
1 resonant tank, 2 side plates, 3 bamboo springs
Embodiment:
With former individual layer quarter sawing maple side plate 2 attenuates, stick on the bamboo spring thin slice 3 that a layer texture is 90 degree orthogonals more inside.
For example, violoncello side plate original thickness is 1.8mm, nexine with the side plate 2 of the maple plate attenuate 0.8mm of quarter sawing cross grain, glue together last layer thickness is 90 degree for the 0.8mm texture bamboo spring thin slice 3 again, behind the hot pressing bending forming, mold is made the qin frame, forms resonant tank 1 with panel, backboard gummed again.
The utility model is applied widely, not only is used for violin series (large, medium and small, times bass) resonant tank, also is applicable to other stringed instrument resonators, as national bass fire do not think, Ruan and guitar etc., all can implement by technique scheme.For national stringed musical instrument two-stringed Chinese fiddle resonance tube, then the bamboo spring is affixed on redwood class qin tube inwall and gets final product.
