Abstract
A kind of improved modulation system of perpendicular an ancient plucked stringed instrument is by the pedal that is positioned at base, the modulation mechanism of top chord arm and be connected in pedal and modulation mechanism between drive link form.Drive link is positioned at outside the qin post, thereby is convenient to Installation and Debugging.Be positioned at the device that fine setting drive link length also can be set on the drive link outside the qin post in addition, can adjust easily to guarantee effective traverse of pedal by the performance personnel.
Description
The present invention relates to the improvement of modulation system of vertically stringed music instrument.
Perpendicular an ancient plucked stringed instrument generally is made up of parts such as base, qin post, the top chord arm that modulation mechanism is housed and vertical audio amplifiers, two row's string row vertically are arranged in the audio amplifier both sides by the scale order from high to low, its modulation system is mainly by the modulation pedal that is positioned at base, the modulation mechanism of top chord arm and be connected in pedal and modulation mechanism between drive link form, generally each scale is provided with the such modulation system of a cover respectively.In the modulation system of existing this musical instrument, described drive link is arranged within the qin post snugly, so fabrication and installation and debugging are very inconvenient.In addition, after the long-term use of such modulation system, gap between each part can be strengthened because of factors such as wearing and tearing, thereby influence accuracy in pitch, therefore the connecting thread at drive link two ends plays a part to adjust drive link length so that guarantee the predetermined traverse of pedal, but because drive link is arranged within the qin post, such adjustment is difficulty very, need be undertaken by the professional.
The objective of the invention is for perpendicular an ancient plucked stringed instrument provides a kind of improved modulation system, wherein drive link is arranged on outside the qin post, thereby is convenient to carry out fabrication and installation and debugging.In addition at this set on the drive link outside the qin post, the device of fine setting drive link length can be set, adjust very convenient, can carry out at any time by the performer.
Embodiments of the present invention is described in detail for contrast the following drawings now:
Figure 1 shows that the perpendicular an ancient plucked stringed instrument front view that adopts modulation first kind of embodiment of system of the present invention, do not draw the string row among the figure;
Figure 2 shows that along the sectional view of Figure 1A-A line;
Figure 3 shows that the perpendicular an ancient plucked stringed instrument front view that adopts modulation second kind of embodiment of system of the present invention, do not draw the string row among the figure;
Fig. 4 is first kind of example of the device of the fine setting drive link length that is provided with on the used drive link of modulation system of the present invention;
Fig. 5 is second kind of example of the device of the fine setting drive link length that is provided with on the used drive link of modulation system of the present invention.
As shown in Figure 1, perpendicular an ancient plucked stringed instrument is by base 1, qin post 2, parts such as the top chord arm 4 of modulation mechanism 3 and vertical audio amplifier 5 are housed to be formed, two row's string row (not shown)s vertically are arranged in the audio amplifier both sides by the scale order from high to low, its modulation system is positioned at the modulation mechanism 3 of top chord arm 4 mainly by the modulation pedal 6 that is positioned at base 1, and the drive link 7 that is connected between pedal 6 and the modulation mechanism 3 is formed.Some drive links 7 are vertically arranged along qin post 2 medial surfaces, and as shown in Figure 2, drive link 7 also can be arranged (see figure 2) along the longitudinal fluting on qin post 2 medial surfaces.
Treadle 6, drive modulation mechanism 3 by drive link 7 and can realize modulation.
Consult Fig. 3 now.Be with Fig. 1 difference, the drive link 7 among this embodiment be arranged between two row's string row (not shown)s parallel with string and pass audio amplifier after be connected with pedal.
In addition, a main advantages of the present invention is, be arranged on the device that fine setting drive link length can be set on the drive link outside the qin post, adjust very convenient, can carry out at any time by the performer, so that eliminate the gap of the increasing that causes because of wearing and tearing between each part of modulation system, guarantee the effective traverse of pedal, thereby guarantee accuracy in pitch accurately.
The device of this fine setting drive link length can adopt various prior arts commonly used in the mechanical engineering, and Figure 4 and 5 illustrate two kinds of different embodiments respectively.
As shown in Figure 4, drive link 7 be divided into upper and lower two-section 7 ' and 7 ", on cut 7 ' the lower end and following section 7 " the upper end attack mutual reverse screw thread respectively, upper and lower two-section screws in respectively in the internal thread of a sleeve pipe 8 upper/lower terminals.Sleeve pipe 8 outer circumference surfaces are provided with the adjustment hole of being convenient to finely tune 9, and available suitable spanner inserts, and turnbarrel 8 is so that trace is adjusted the length of drive link 7.
In Fig. 5, drive link 7 upper ends are with screw thread and penetrate in one L shaped 9 the hole of modulation mechanism 3, and the diameter in hole is a bit larger tham the external diameter of drive link 7, and drive link can be slided in the hole, and rotation nut 10 can the micro-length of adjusting drive link 7.
More than describing not is to concrete qualification of the present invention, and the professional and technical personnel can make many variations and not exceed scope of the present invention above-mentioned various embodiment.The described various embodiment of this instructions also have more than and are applicable to perpendicular a kind of musical instrument of an ancient plucked stringed instrument in addition, also can be applied to harp and be equal in the kind musical instrument.
