Summary of the invention
It is less to the objective of the invention is to solve in the prior art urheen volume, the tone color thickness low LCL, and the brightness of sound is also poor, the problem that range is wide inadequately.
Technical solution of the present invention design voice-amplified urhu, its feature: the qin tube is long a little, qin tube right-hand member has the qin skin, qin tube right-hand member is outer anistree, outer anistree upper and lower the other side is wider big, and remaining left and right outer-hexagonal the other side width equates that outer anistree left part is the middle part that the vertebra degree is arranged slightly, the middle part connects waistband, and the left end of waistband is the loudspeaker external diameters.The right part of loudspeaker internal diameter is interior anise, and the right part of interior anise is interior R groove, and the right-hand member of interior R groove (endoporus of qin tube right-hand member) is the internal diameter that the vertebra degree is arranged slightly.Advantage of the present invention is flat octagonal voice-amplified urhu, and upper and lower the other side is wider big: increase brightness, flat hexagonal left and right sides the other side: increase thickness, qin tube lengthening: broadening range, left end loudspeaker: strengthen volume.
Embodiment
Fig. 1 is a voice-amplified urhu qin tube front view, its feature among the figure: upper and lower the other side 1 of outer anistree qin tube is wider big, upper and lower the other side's 1 rear portion is the internal diameter 2 that the vertebra degree is arranged slightly, the rear portion of internal diameter 2 is interior R grooves 3, the rear portion of interior R groove 3 is the upper and lower theother side 4 of interior anise, outer anistree except that upper and lower the other side 1 wider big, left and right the other side's 5 width of remaining hexagonal equate, the left and right the other side's 5 of outer-hexagonal internal diameter 6, the vertebra degree is arranged slightly, the rear portion of internal diameter 6 isinterior R grooves 7, and the rear portion ofinterior R groove 7 is that left and right the other side's 8 width of interior hexagonal equate that qin tube front end is aqin skin 9.
Fig. 2 is the voice-amplified urhu rear view, loudspeaker external diameter 11 among the figure, theinternal diameter 10 of loudspeaker, the front portion of loudspeaker is interior anises, interior anise except that upper and lower theother side 4 wider big, remaining in left and right the other side's 8 width of hexagonal equate, the loudspeaker front end is outer anistree, outer anistree except that upper and lower the other side 1 wider big, left and right the other side's 5 width of remaining outer-hexagonal equate that the front end of loudspeaker isqin skins 9.
Fig. 3 is the voice-amplified urhu side perspective, the top of qin tube right-hand member is that outer anistree upper and lower the other side 1 is wider big among the figure, qin tube right-hand member is aqin skin 9, the left and right of upper and lower the other side 1 is outer-hexagonal theother side 5, the internal diameter 2 of qin tube right-hand member has a vertebra degree, the left part of internal diameter 2 is R grooves 3 in upper and lower the other side, the left part of interior R groove 3 is the upper and lower theother side 4 of interior anise, interior anistree upper and lower the other side's 4 left end is a loudspeakerinternal diameter 10, the external diameter 11 of loudspeaker, loudspeaker external diameter 11 connectswaistband 12, and the right part ofwaistband 12 is the outer middle parts 13 of qin tube, and the vertebra degree is arranged slightly.
Fig. 4 is the voice-amplified urhu structural map, the figure middle and lower part is a qin tube 15, the bottom of qin tube 15 is collets 16, the right-hand member of qin tube is aqin skin 9, qinsign indicating number 14 is arranged on theqin skin 9, qin tube right-hand member top is on the outer anise, following wider big the other side 1, a remaining left side, right outer-hexagonal theother side 5 width equate that the middle part 13 of qin tube connectswaistband 12, the left end ofwaistband 12 is external diameters 11 of loudspeaker, on, be qin bar 22 on wider big the other side 1 down, the upper end of qin bar 22 is scroll heads 18, and the top of qin bar 22 is interior pegs 19, interior peg under slightly is outer peg 20, the below of outer peg is very heavy 21, in, outer peg 19, in on 20 being, outer string 17, urheen is furnished with bow stick 23, bow hair 24 is arranged on the bow stick, and the bow stick right-hand member is a bow hair parbuckle screw 25.The present invention is flat-shaped anistree qin tube, because of upper and lower two the other side wider big: increase VDF, the horizontal degree of left and right sides the other side is widened: increase tone color thickness, qin tube lengthening: range broadening, horn shape: volume is amplified.
