Abstract
The utility model provides a combined type violin family bass bar comprising a bass bar body in the shape of a quadrangular prism. The bass bar body is formed by splicing the side surfaces of two daughter bass bars in the shape of a quadrangular prism. The daughter bass bars are the same in terms of size and shape. The joint between the two daughter bass bars forms a splicing surface. The annual ring directions on the end faces of the two daughter bass bars are distributed symmetrically with the splicing surface as the plane of symmetry. Compared with the prior art, the combined type violin family bass bar is formed by splicing two daughter bass bars which are the same in terms of size and shape and whose annual ring directions are distributed symmetrically, so that the impedance characteristic of the combined type violin family bass bar for signals tends to be uniform, the sounding quality of the violin family can be greatly improved and the sound made by the musical instruments can be powerful, even and full. The combined type violin family bass bar enables the sounding effect the same as that of the conventional bass bar made of better timer such as fir to be achieved with timber with common quality.
Description
Technical field
The utility model belongs to musical instrument technical field, relates to the accessory sound beam in shell-and-plate stringed instrument, particularly a kind of compound violin bass bar.
Background technology
Violin sound beam is again bass bar, is a kind of wooden crossbeam being installed in violin resonant tank, conventionally glued together with resonant tank soundboard, and sound beam has the effect of adjusting violin tone color and support violin soundboard anticracking.
Sound beam of the prior art is all the solid wooden sound beam of strip, as shown in Figure 1-2, the sound beam body 2 being formed in one, sound beam body 2 is to be made up of timber, because the annual ring direction 21 of timber is the circle of multiple mutual sockets, cut thus a part that only intercepts strip while making, its annual ring direction 21 is not often symmetrical, but can be with arc-shaped bend, and entirety is mal-distribution, this just causes vibrational waveform inhomogeneous and distort, and intensity of phonation is inadequate.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of compound violin bass bar of the pronunciation quality that can greatly improve violin, uses this sound beam, can make violin sounding powerful, all even plentiful.
The utility model provides a kind of compound violin bass bar, comprise sound beam body, described sound beam body be shaped as cubic cylinder, it is characterized in that, described sound beam body is that the secondary sound beam of the cubic bar shape identical by two size shape is spliced mutually by side, the joint of two secondary sound beams forms Mosaic face, and the annual ring direction on the end face of two secondary sound beams is all symmetry arrangement take Mosaic face as the plane of symmetry.
The annual ring direction of each secondary sound beam and the angle of Mosaic face are and are greater than 0 degree and are less than 45 degree.
The annual ring direction of each secondary sound beam and the angle of Mosaic face are 1-30 °.
The end face of described sound beam body is rectangle, and described Mosaic face is parallel to the large side of surface area of sound beam body.
Described sound beam body is to be made up of timber, and the wood grain trend of described timber parallels with the Mosaic face of sound beam body.
Described sound beam body is to be mutually bonded by side by two secondary sound beams.
Compared with prior art, the compound violin bass bar that the utility model provides adopts two identical secondary sound beam side spelling groups of two size shape to form, and the annual ring direction of the end face of two secondary sound beams is all symmetry arrangement take Mosaic face as the plane of symmetry, the splicing of identical by two size shape like this and secondary sound beam that annual ring direction is symmetric, just make its impedance operator to signal be tending towards even, thereby greatly improve the pronunciation quality of violin, made musical instrument sounding powerful, all even plentiful; In addition, the compound violin bass bar of the utility model can reach and adopt good timber as the sounding effect of traditional sound beam of China fir with the timber of normal quality.

Embodiment
The utility model provides a kind of compound violin bass bar, as shown in Figure 3-4, comprise sound beam body 1, described sound beam body 1 be shaped as cubic cylinder, described sound beam body 1 is that the secondary sound beam 11 of the cubic bar shape identical by two size shape is spliced mutually by side, two secondary sound beams 11 can be by being laser-cut into, and the annual ring direction 13 on the end face of 12, two secondary sound beams 11 of joint formation Mosaic face of two secondary sound beams 11 is all symmetry arrangement take Mosaic face 12 as the plane of symmetry.Like this by the splicing of two symmetrical secondary sound beams 11, just make its bending strength to Mosaic face 12 and the impedance operator of signal be tending towards evenly, thereby greatly improved the pronunciation quality of violin, make musical instrument sounding powerful, all even plentiful.
The annual ring direction 13 of each secondary sound beam 11 is and is greater than 0 degree and is less than 45 degree with the angle of Mosaic face 12.Further preferred, the annual ring direction 13 of each secondary sound beam 11 is 5-15 ° with the angle of Mosaic face 12.The end face of described sound beam body 1 is rectangle, and described Mosaic face 12 is parallel to the large side of surface area of sound beam body 1.The wood grain trend of described timber preferably parallels with the Mosaic face 12 of sound beam body 1.
Described sound beam body 1 is to be made up of timber, is preferably by China fir and makes.The kind of China fir is a lot, more preferably fish scale dragon spruce, fish scale dragon spruce texture is straight and even, property is slightly soft, moderate strength, high resilience, easily vibration and transaudient speed fast, but the compound violin bass bar of the utility model can reach and adopt good timber as the sounding effect of traditional sound beam of China fir with the timber of normal quality.In addition, existing seven-stringed plucked instrument in some ways similar to the zither tonequality is mellow, but insufficient strength often adopts the compound violin bass bar of the utility model, can greatly improve its intensity, thereby the quality of lifting sound that can be larger has wide market outlook.
