Abstract

The utility model provides a zheng, 21-or 25-stringed plucked instrument, comprising a tone cavity, an instrument seat for supporting a tone beam, arranged in the tone cavity, an instrument cover arranged on the instrument seat, and instrument strings and instrument string codes arranged on the instrument cover, characterized in that the back side of the instrument cover is provided with the tone beam, and the lower end of the tone beam is arranged in the tone cavity of the instrument seat, thereby not only enhancing the resonance effect of the instrument tone in the instrument seat and increasing the timbre and volume, but also enabling the instrument tone to be fluent, clear, melodious, silvery and bright. The arrangement of liquid groove for supporting the top of the tone beam, and of the middle vertical tone post effectively enables the high pitch penetrating power to be increased and the middle pass to be vigorous and powerful, and thereby when the zheng, 21-or 25-stringed plucked instrument is played, the timbre is more accurate and the lingering sound is more long-drawn-out. Additionally, the scheme also enables the strength and toughness of the instrument cover to be increased, and thereby the instrument is more elastic, the instrument string codes are more stable, and the instrument strings are unnecessary to be adjusted.

Description

A kind of Zheng

Technical field

The utility model relates to a kind of Zheng, and the Zheng that particularly a kind ofly have a beautiful tone, tonequality is good belongs to musical instrument design and manufacturing technology field.

Background technology

Zheng is the distinctive a kind of national musical instruments of China, enjoys liking of people over the past thousands of years.Traditional Zheng owing to lack the sympathetic response device in the sound chamber, too loose, the unable problem of pronunciation often occurs when therefore playing, while Zheng volume is too little, and the lingering sound when playing is very short.This has not only greatly influenced the music effect when Zheng is played, and in order to increase volume and to increase lingering sound by artificial mode, just must carry out the configuration of sound equipment and amplifirer accordingly, so just increase operating cost greatly, and the preliminary work before playing is comparatively loaded down with trivial details.Especially for large-scale band or large-scale concert, more need to drop into a large amount of apparatuses and human and material resources, make the operation cost of a performance too high, bring no small trouble, allow spectators be difficult to enjoy more beautiful, interesting to listen to Zheng music to operator.In addition, traditional Zheng also exists sound instability and string slack and undisciplined, needs problems such as frequent tuning.Therefore be necessary prior art is improved.

Summary of the invention

Unresolved existing Zheng is loose because of the qin sound that unreasonable structure exists, and volume is little, and lingering sound is short, and the string sign indicating number slides when playing easily, needs problems such as frequent tuning, and the utility model provides a kind of Zheng of tone color enhancement mode.

The utility model is finished by following technical proposal: a kind of Zheng, comprise and establish the qin seat that supports the sound beam in band sound chamber and the sound chamber, be located at the qin lid on the qin seat, be located at string and string sign indicating number that qin covers face, it is characterized in that the Qin Gai back side is provided with the sound beam, the lower end of this sound beam places in the sound chamber of qin seat, to increase volume, prolongs lingering sound.

The sound beam at the described Qin Gai back side is a bass bar, and the axis of bass bar intersects with qin lid axis, so that the oblique Qin Gai back side of being located at of bass bar to strengthen the sympathetic response effect, makes the Zheng pronunciation clear and melodious bright.

The top of the support sound beam in the described qin seat sound chamber is provided with the fluid sound groove at interval, so that transmit the qin sound by the fluid sound groove, and improves the flow direction of qin sound, prolongs lingering sound.

Through hole is established at support sound beam middle part in the described qin seat sound chamber, establishes movable perpendicular sound column in this through hole, to improve Zheng tone color and volume.

The perpendicular sound column of described activity is made as a plurality of of differing heights, so that adjust the position of perpendicular sound column in supporting sound beam through hole as required, to satisfy the requirement of different tone colors and volume.

Described qin seat comprises the vertical plate of base plate and base plate periphery, and the base plate left side is provided with manhole, and the base plate right side is provided with the waveform through hole, to increase qin sound volume.

The utlity model has following advantage and effect: by bass bar being set at the Qin Gai back side, not only can strengthen the sympathetic response effect of qin sound in the qin seat, tone color and volume have been improved greatly, also make qin sound smoothness, clear, excellent poplar, clear and melodious, bright simultaneously, the setting of erecting sound column by the setting and the middle part of support sound back portion fluid sound groove effectively improves the high pitch penetration power again, bass is simple and honest strong in making simultaneously, thereby when Zheng is played, make tone color more accurate, lingering sound is longer simultaneously; Such scheme has also strengthened the strength and toughness of qin lid in addition, makes it to be rich in elastic force, and the string sign indicating number is stable, need not often to tune a stringed instrument.Be a desirable Zheng in fact.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The Zheng that the utility model provides, comprise and establish the qin seat 4 that supports sound beam 3 in band sound chamber 2 and the sound chamber 2, be located at the qin lid 12 on the qin seat 4, be located at string and string sign indicating number above the qin lid 12, wherein qin covers 12 back sides and is provided with sound beam 13, this sound beam 13 is a bass bar, and the lower end of bass bar 13 places in the sound chamber 2 of qin seat 4, and the axis of bass bar 13 covers 12 axis with qin and intersects, so that the bass bar 13 oblique qins of being located at cover 12 back sides, as Fig. 4,, prolong lingering sound to increase volume; The top of the support sound beam 3 in the described qin seat 4 sound chambeies 2 is provided with fluid sound groove 10 at interval, so that transmit the qin sound by fluid sound groove 10, and improves the flow direction of qin sound, prolongs lingering sound; Through hole 5 is established at support sound beam 3 middle parts in the described qin seat 4 sound chambeies 2, establish movable perpendicular sound column 11 in the through hole 5, movable perpendicular sound column 11 is made as a plurality of of differing heights, as Fig. 3, so that adjust the position of perpendicular sound column in supporting sound beam through hole as required, to satisfy the requirement of different tone colors and volume; Described qin seat 4 comprises the vertical plate of base plate 7 and base plate 7 peripheries, and base plate 7 left sides are provided with manhole 8, and base plate 7 right sides are provided with waveform through hole 6, to increase qin sound volume, be provided with string fagging 1 in the sound chamber 2 of qin seat 4, be fixed with string erection column 9 on the string fagging 1, as Fig. 2, Fig. 1.
