Description

Novel double string konghou

Technical Field

The invention belongs to the technical field of musical instruments, and particularly relates to a novel double-row string konghou.

Background

Application No.: CN85200599, entitled double-row string vertical code type pressing flutter full-modulation konghou, is the first double-row string vertical code type pressing flutter pedal full-modulation konghou applied by the applicant in 1985. Due to the successful development of the konghou, the performance professions of the konghou are successively opened by some mainstream music academy in China. The national band example is the establishment of formal vocal ministry, and although the application of more than 30 years is improved and perfected for many times, the problems of complex structure, easy generation of abnormal sound, complex tone adjustment and the like are difficult to solve.

The basic structure of the piano is as shown in fig. 12, and comprises a vertical resonance box consisting of a left side soundboard 300, a right side soundboard 400 and a sound box bottom frame 200, a support column and a curved tuning peg board, wherein the inverted triangular piano body frame structure is formed, the vertical resonance box is clamped between a left side string 500 and a right side string 700, and the left side string 500 and the right side string 700 are supported on the left side soundboard 300 and the right side soundboard 400 of the sound box by using a bridge 600 respectively as sound guide bodies. Left side string 500 and right side string 700 lower extreme are hung and are set up on audio amplifier base frame 200 in the rigidity is pressed the recess of quivering device 100 both ends roll adjustment screw for audio amplifier left side string 500 and right side string 700 link as an organic wholely, and the other end of two chords that correspond twines respectively on the peg on the curve peg board, through rotatory peg, and the tensioning string is adjusted to the accuracy of sound of settlement, and the square can be played.

The tension of one side string is changed simultaneously through pressing the other side string, the effect of tremolo can be produced during playing, the pressure quivers the device to be located the part of the movable balance bar that has the triangle sword strong point in the middle of the sound box base frame, the sound box both sides string hangs respectively in the recess on the recess screw at balance shaft both ends, transfer one side string must influence the pitch of opposite side string, and the musical instrument sign indicating number also is a movable part, can produce the displacement perk during the accent musical instrument, need adjust the operation requirement that can reach repeatedly several times, as shown in fig. 12.

Because the side soundboard passes through the sign indicating number bridge support conduction about two rows of strings are respectively through the vertical case of writting altogether in the centre, and the both sides soundboard is the independent pronunciation of branch differentiation, and this can lead to there being certain difference in the both sides soundboard stereo set. A section of melody in playing is often finished by connecting a left hand and a right hand, when the left hand and the right hand play, the left hand and the right hand pronounce independently through a left sound board and a right sound board, the sounds are different, repeated string pressing easily causes the displacement of a musical instrument code, the accuracy of sound is influenced, the directionality of sound is inconsistent, and the like.

Disclosure of Invention

The invention aims at the problems and provides the novel double-row string microphonic konghou which is clear in sounding sound directivity, pure in sound and good in stability.

In order to achieve the above purpose, the invention adopts the following technical scheme that the invention comprises a resonance box, wherein the resonance box is provided with upright posts and chord shaft plates, and a suspended auxiliary beam is arranged between the resonance box and the chord shaft plates, and the invention is characterized in that: the two sides of the soundboard of the resonance box corresponding to the suspension auxiliary beam are provided with double rows of strings, and each string is connected with the peg body at the other side of the peg board after passing through the suspension auxiliary beam at the same side.

As a preferred scheme of the present invention, the suspension auxiliary beam is provided with a sound changer matched with the strings, the sound changer comprises a rotating shaft arranged on the suspension auxiliary beam, the rotating shaft is provided with a rotating disc, and the rotating disc is provided with string-cutting posts matched with the strings.

Furthermore, the rotating shaft is connected with a crank, the crank of the sound changer of each same sound name sound group is connected with a linkage rod in the suspension auxiliary beam, and one end of the linkage rod is provided with a steering component.

Further, one end of the steering member is connected to a pedal box at the bottom of the resonance box by a stay.

Furthermore, a height adjusting support is arranged between the resonance box and the pedal box.

Furthermore, a pedal rod is arranged in the pedal box, and one end of the pedal rod is connected with a hinged support inside the pedal box; the brace is connected with the middle part of the pedal rod.

As another preferable scheme of the present invention, the upper end of the auxiliary suspension beam is provided with a nut of the string.

Furthermore, the capo comprises two opposite L-shaped fixing seats, and a rotating wheel is arranged between the two fixing seats through a rotating shaft.

Furthermore, the fixed seat is connected with the auxiliary suspension beam through a long hole bolt assembly.

Furthermore, the rotating wheel is provided with a string groove.

The invention has the beneficial effects that: the double-row string structure directly connects the double-row strings with the soundboard without using a bridge as a sound guide body, and has the advantages that: the two rows of strings are tied on a soundboard, the sound directivity of the sound is clear, more copies are not available, the sound is pure, and convenience is provided for users; due to the structural characteristics of the suspended auxiliary beam, the string section between the suspended auxiliary beam and the peg body is crossed to be stringed left and right, so that the string is strung by the right hand, the same string suspended auxiliary beam is pressed to the string section on the peg board by the left hand to generate the tremolting effect, and on the contrary, the string is strung by the left hand, and the same string suspended auxiliary beam is pressed to the string section on the peg board by the right hand to generate the same tremolting effect. The diversification of musical instruments meets the requirement of multiple cultural spirits of people, so the musical instruments also exist relatively, the single-row string konghou has pure sound, is convenient to adjust and is beneficial to popularization, the double-row string konghou has more abundant sound and has inspiration because of the resonance on objective acoustics, and the other double-row strings are played at the melody and polyphonic accompaniment sound parts simultaneously, so the completeness of the two sound parts can be kept, and various different tuning modes can be provided; the suspended auxiliary beam structure also solves the problems of sound directivity dispersion, more movable parts, difficulty in adjusting sound level, poor stability, easy generation of abnormal sound and the like of the traditional vertical code type konghou. Therefore, the double-row string konghou and the single-row string konghou of the 'suspended auxiliary beam' can achieve the characteristic of perfectly expressing the instrument. The ancient plucked stringed instrument lost for more than three hundred years returns to the real culture life of people again with rich expressive force and an ancient plucked stringed instrument closer to the traditional structure state.
