Embodiment:
Below in conjunction with drawings and Examples structure of the present utility model and principle of work and the course of work are elaborated:
As shown in Figure 1, the utility model comprise qin axle 1, the string of a musical instrument 2, audio amplifier 7, snakeskin 8, main bridge 9, very heavy 10 and copper axle micro-adjusting mechanism constitute, qin axle 1 bottom is fixed with audio amplifier 7, top is fixed with copper axle micro-adjusting mechanism, the string of a musical instrument 2 upper ends are fixed on the twisted wire wheel 12 of copper axle micro-adjusting mechanism, the lower end is fixed on the hook nail 3 of audio amplifier 7 bottoms, and qin axle 1 medium position has the string of a musical instrument 2 of very heavy 10 tension relevant positions, the utility model improvement part following points:
1) string of a musical instrument 2 bottoms fixing: be to adopt a bamboo head to make 90 degree hook nails two strings of a musical instrument are hooked on the hook nail 3 in the audio amplifier bottom.Fix about string of a musical instrument bottom, can have three kinds, one is exactly that the existing hook nail of making of metal hooks; It two is to make two hook nails with the mao bamboon head, fixes as the bottom of two strings of a musical instrument.The 3rd, be to make a hook nail 3 as two common stiff ends in the string of a musical instrument 2 bottoms with the mao bamboon head, the string of a musical instrument 2 up is pressed on the main bridge 9 of snakeskin 8 medium positions that are pressed in the sidepiece that is positioned at audio amplifier 7 on the tuning tongue piece 11 more then.Being exactly of above-mentioned three kinds of method the bests made 90 with a mao bamboon head and spent hook nails two string of a musical instrument bottoms are fixed together, and the bottom is connected on the point mutually.Such product tonequality is transparent, and tonequality is good.Why make hook nail and fix the meeting of two string root tonequality better with a mao bamboon head? here we will illustrate the trend of sound wave: after the horse hair bow hair stridulate of two strings, master volume very heavy with down between the audio amplifier, string of a musical instrument bottom 90 degree are fixed on the audio amplifier bottom, but its some lingering sound, if make hook nail with metal, it can consume volume, if being fixed on the supporting plate, string of a musical instrument bottom also can consume a part of volume, so make hook nail with a mao bamboon head, tonequality is better, be that it is better to reach sound tonequality because the hook nail that the remaining bottom of string is done through the mao bamboon head is passed to audio amplifier.
2) why urheen has noise, wolf sound, main relevant with material and technology, be exactly 9 pairs of snakeskins of main bridge, 8 pressure tensions in addition, make it lose better elasticity, air humidity is big, snakeskin 8 is soft to be fallen, and the sound bullet does not get up, air drying, main bridge 9 pressure are too tight again, sound yet bullet does not get up, and the wolf sound is sent in the meeting that has, and it is very ear-piercing that the people sounds.At two problems in front, the inventor has done long term studies: reaching a conclusion is that any metal parts can not be used; Present improved way is to make a series of tuning tongue pieces 11 different in size with the mao bamboon head, select the tuning tongue piece of suitable length according to tune, individual demand, its structure is: tuning tongue piece 11 1 ends withstand on the wire-hanging hook of hook nail the other end and are pushed down by two strings of a musical instrument 2.The tuning tongue piece has two effects, changes tuning tongue piece length and changes the purpose that main bridge 9 pressure reach change tonequality; Pressure is big, and main bridge and snakeskin vibration frequency height, sound are just high; Main bridge and snakeskin pressure are little, and vibration frequency is low, but the big tonequality of amplitude is lower, thus tangible tuning effect, and this tonequality that existing urheen will reach the inventor's product is impossible.
3) material is made three with mao bamboon and is gone up bridge 4,5,6, this be before the urheen structure unexistent, this go up bridge to change copper axle tonequality, stablize the tone color effect very big, used these three kinds on bridges, the sound of musical instrument of copper axle not only can not degenerate, better on the contrary, tone color is more rough, and present old-fashioned urheen adds also can be better with these three last bridge tone colors, with last bridge, even copper axle bowing is very heavy, as imitate the clippety-clop bow of cutting, its tone can not become.Concrete structure is: go up bridge 4,5,6 for three and fix by coiling coiled knot; Go up bridge for every and be provided with perforation, the string of a musical instrument 2 other ends up pass the perforation of bridge 4,5,6 and get on and the twisted wire wheel 12 of copper axle micro-adjusting mechanism is fixed through very heavy 10.
4) why not handy the copper axle fine setting before is, and reason has two, and the first has been used behind the copper axle original pleasing to the ear tone color variation, and reason is because last lingering sound is absorbed by the metallic copper axle to consume, and makes the poorer reason of tonequality elasticity; Its two be before the people of design because do not expect, in order to keep outward appearance, usefulness be that turbine is below front end, very long back, scroll bar position, so in use mechanically be called and walk because of playing turbine, worm screw that vibrations cause, string of a musical instrument degree of tightness has changed, and causes that sound of musical instrument gets out of tune.Improve the turbine on the mechanics of making an exception, the theory of scroll bar " worm screw is descending at last, turbine " at two problems above the fine setting of copper axle.We adopt new structure i.e. " worm screw down, turbine is last ", copper axle micro-adjusting mechanism concrete structure is to comprise shell 13, axle 14, turbine 15, worm screw 16, twisted wire wheel 12 and hold-down nut 17, shell has axial trough 18 in 13 1 ends, shell is provided with turbine groove 19 in 13 the other end, the turbine groove 19 mid-turbines that are placed with 15, shell 13 sides are provided with worm screw locating slot 20, worm screw 16 1 ends insert in the side worm screw locating slot 20 of shell 13 location and can rotate, worm screw 16 other ends are fixed with knob 21, are convenient to rotary worm; Axle 14 1 ends penetrate in the axial trough 18 that is provided with in shell 13 1 ends and by the convex edge that its other end is provided with and are stuck in outside the axial trough, the axial trough that axle 14 1 ends penetrate shell one end enters turbine central shaft hole in shell 13 the other end turbine grooves 19 and passes that to place the outer twisted wire of shell 13 other ends to take turns 12 center pits fixing by nut 17 again, and the turbines 15 in the shell 13 are located at, worm screw 16 is located at down and turbine 15, worm screw 16 are connected with a joggle.The knob 21 of the rotary worm other end just makes worm screw rotate and drives turbine, twisted wire wheel and axle rotation, and the twisted wire wheel is finely tuned the string of a musical instrument.This structure is used in string music and well but finely tunes again, and the string of a musical instrument is received tightly more, and turbine and worm is big painstakingly more, and tone is just steady more.Be that the scroll bar position is short and all at front end in addition, play former you how to shake, mechanical component can not cause that the gap walks, and causes that musical instrument gets out of tune.This mechanical tuning device, the band fine setting improves urheen, and two great advantage are arranged: the one, simple structure is done well, and cost is low; Its two urheen of being had been friends in the past just can become the outer tuning urheen of machinery of the present utility model through transforming.Twisted wire rod among the utility model figure does not play the twisted wire effect, as keeping original surface structure, is that turbine, the worm screw of adopting copper axle micro-adjusting mechanism regulated and regulate the string of a musical instrument just.
