Embodiment
The first embodiment: Fig. 1 Fig. 2 Fig. 3 has introduced a kind of large range matouqin, comprises qin bar 1, audio amplifier 2, string code 3, string 4, qin axle 5, bow (not shown), visible in conjunction with Fig. 5 Fig. 6 Fig. 7: the panel 7 of audio amplifier 2 adopts arc cambered plate.This cambered plate is different from the panel of the thin thick middle of existing surrounding, and existing panel is outer middle side part evagination slightly only, and inner side is plane, though load performance is better than uniform thickness panel, the amplitude improving is little.And it is all outwardly inside and outside this routine panel, visible in conjunction with Fig. 4: the arch height h=10-20mm of panel section.The pressure of string code 3 directly passes to the frame of audio amplifier 2, and load performance significantly improves, and string 4 can be stretched even tauter, and sound equipment is more loud and sonorous resonant, and the volume of audio amplifier 2 obviously increases, sympathetic response effect strengthens, and audio amplifier intensity obviously improves, not yielding, tone is more stable, longer service life.
In conjunction with Fig. 5 Fig. 6 Fig. 7, be also shown in: string code 3 moves on to the bottom of audio amplifier from the middle and upper part of original Loudspeaker panel 7.Preferably, at golden section point place, the bottom of panel 7, establish audio amplifier height a=1, the horizontal central line of string code 3 is to distance b=0.618 of panel 7 coboundarys.Experimental results demonstrate, string code 3 moves on to bottom, has been equivalent to improve the position of drawing string point, contributes to strengthen high pitch.In addition, string code 3 moves down has also abdicated upper space, to offer large-area sound hole.As shown in the figure, the upper middle part of panel 7, string code 3 directly over have sound hole 6.The shape of sound hole 6 can be varied, can be one of rectangle, circle, ellipse, polygon.But the total area of sound hole 6 should be greater than 25cm
2.This sound hole 6 is just in time in drawing between string point chord code 3, and sympathetic response effect is significantly improved.
Experimental results show that: by above-mentioned improved matouqin, its bass effect is unaffected, still can send overcast serious sound equipment, kept the traditional local flavor of matouqin.On this basis, its treble is effectively expanded, and formation can be high or low, and bass is vigorous rough, and the artistic characteristics that high pitch is golden sound and jade vibration makes ancient matouqin shine more mysterious charming color.
The second embodiment: visible in conjunction with Fig. 8 Fig. 9: the lower end of qin bar 1 is connected with the wainscot in audio amplifier 2, and not by audio amplifier 2.Space in audio amplifier 2 increases, and has eliminated the interference of 1 pair, qin bar audio amplifier wallboard vibration wave around, and vibrating effect significantly strengthens.
The third embodiment: visible in conjunction with Figure 10 Figure 11: variation has occurred wood grain 10 trends of Loudspeaker panel 7, wood grain is the fiber pattern of wooden wallboard, the wallboard that matouqin adopts mostly at present is linear texture, and is setting installation, and the direction of wood grain is parallel with string.Experiment discovery, the direction of xylogen texture has certain effect for sound wave propagation tool, and the wood grain of setting is conducive to the vertical propagation of sound wave, and is unfavorable for the horizontal transmission of sound wave.Because string 4 itself is exactly vertical, and be the prepreerence transmitting carrier of sound wave, it is also vertical adding wallboard wood grain around, the condition that sound wave is vertically propagated is better than the condition of horizontal transmission far away, cause thus the unicity of the direction of propagation, consequently reduce the sympathetic response effect of sound wave, reduce source of sound audio frequency effect around.Based on this understanding, this example is wallboard wood grain 10 horizontal positioned of audio amplifier, vertical with string 4.Since 2012, adopt double-blind study to carry out many people audition repeatedly and pass judgment on, player and hearer are all in unwitting situation, and the performance of passing through is listened and commented marking, and carry out statistical treatment, result shows: the suggestion orientation that horizontal wood grain acoustics is better than vertical wood grain is highly consistent.Particularly the wood grain horizontal of panel 7 has the greatest impact to acoustics.The backboard 8 of audio amplifier and the wood grain 10 of side plate 9 are taken second place, but also have higher using value.
