Abstract
The invention is a kind of duplicate resonator which is fixed in the chord musical instrument resonant box or resonant pipe. Its position is near to the back of oscillating source bridge. On the premise of maintaining the features of various types of chord musical instruments, the musical instrument acoustic structure of the primary single resonant cavity can turn into acoustic structure of duplicate resonant musical instrument, as long as fixing the invention. So it can amend in a large extent the acoustic quality of musical instrument, that is to say, augmenting volume, longer aftersound and prettifying tamper to make musical instrument more sonorous, melodious and fair-sounding. The invention has simple structure, easily making, easily fixing, extremely economical investment, remarkable effect.
Description
Technical field:
The invention belongs to the instrumental acoustics structural improvement of chord crying musical instrument resonator (case or tube).
Background technology:
The structure of chord crying musical instrument mainly is divided into sounding body and resonant two parts.String is that sounding body when vibration volume is fainter, in order to obtain big volume, and the vibration that must strengthen and play up sounding body by resonant (being resonator) as the qin tube of urheen, the qin case of violin.Chord crying musical instrument is divided three classes according to the playing method difference: 1, plucked instrument such as Ruan, Chinese lute, guitar etc.; 2, bowed stringed instrument (also claiming bowed instrument) is as urheen, violin etc.; 3, hammered string instrument such as dulcimer etc.On the structure of Chinese and Western chord crying musical instrument, to form by scroll head, qin bar (neck), body, body is resonant tank or resonance tube.No matter resonant tank or resonance tube, it all is the resonator of different musical instrument shape systems, its effect is to vibrate when stressed the exciting of string, pass by the sign indicating number bridge again and shake to panel or epithelium, sound wave promptly produces resonance in resonator, thereby enlarged volume, beautified tone color, musical instrument just sends loud melodious musical sound.Getting well with inferior of instrumental acoustics quality (volume, tonequality, tone color), resonator plays crucial effects.Though various chord crying musical instruments are because shape system difference, resonator (body) different plays the sympathetic response effect and all produces in single cavity (case or tin) and carry out.And the function of single resonator (case or tube) has certain limitation, and is more obvious for the acoustic quality influence of musical instrument: the volume decay as the urheen treble is serious; The guitar resonant tank is very big, and volume is little; Chinese lute always has some grade lingering sounds short (being commonly called as dead sound); The exercise of violin class with qin be middle-grade and universal class mostly sympathetic response is relatively poor, tonequality is relatively poor, plank is highly seasoned.
Summary of the invention:
The object of the invention is intended to not change under the original organ for resonance prerequisite of musical instrument, the present invention's (complex resonator) is installed in employing in the chord crying musical instrument resonator, musical instrument becomes multiple resonance instrumental acoustics structure by former single resonator acoustic construction, can improve the acoustic quality of musical instrument by a relatively large margin.
Technical scheme of the present invention: as shown in Figure 1, resonance tube 1,2 parallelly tightly are pasted together, at resonance tube 1,2 middle part has through wind 3 up and down, be that rectangular through holes is wide 2～4 millimeters, be about 25～40 millimeters, 0.8～1 millimeter of the wall thickness of resonance tube, 16～25 millimeters of diameters, two resonance tube diameters are than being about 4: 5 for good, resonance tube 1,2 length is to decide according to the size of rubbing down or tube, can between 60～200 millimeters, select for use (as urheen 65 millimeters long, violin 100 millimeters long, violoncello 200 millimeters long), two resonance tubes are the wood with same length, bamboo or engineering plastics are made, two ends are with the celluloid foil seal and corner angle limit cavetto, two resonance tubes 1,2 parallel being close together, the middle part is installed with the extension silk 4 that is used for fixing, so that be fixed in rubbing down or the resonance tube, and it not only can freely have been trembleed but also can not brush up against resonant tank up and down or the wooden partition of tube is as the criterion, hang the phosphorus copper wire of 0.8～1 millimeter of silk 4 usefulness diameter and make, also can adopt other bronze wires or spring steel wire to make.

Specific embodiments:
The present invention is embodied as example with violoncello, as shown in the figure: adopt big resonance tube 1,2 wall thickness are 1 millimeter engineering plastics pipe, two ends celluloid foil seal, the diameter of resonance tube 1 is 25 millimeters, the diameter of resonance tube 2 is 20 millimeters, two length of tube all are 200 millimeters, air port 3 be 40 millimeters of wide 4 millimeters long to reach through hole, upper aperture is over against vibration source sign indicating number bridge place, adopt the phosphorus copper wire of 0.8 or 1 mm dia to hang that silk 4 is fixed on the violoncello back side of panel bass bar and parallel with it, hang the length of silk 4 and installation site with: 1, complex resonator can not run into violoncello resonant tank wooden partition and bass bar is as the criterion up and down in the chord crying musical instrument resonator when performance is rocked; 2, when playing, complex resonator can freely tremble in the chord crying musical instrument resonator.Improved like this violoncello can increase volume when playing, lingering sound is elongated, beautifies sound quality, and its acoustic quality improves by a relatively large margin, and musical sound is more loud, and is melodious, interesting to listen to.
Chord crying musical instrument for the similar violoncello of other resonant tank, draw thunder, Chinese lute suddenly as violin, viola, Double bass and guitar, Ruan, national bass ... Deng, adopt in the above-mentioned chord crying musical instrument resonator complex resonator installation method and require to implement to get final product, its size fibrous root stradivarius resonant tank volume size matches and makes.
For the two-stringed Chinese fiddle resonator is the musical instrument of resonance tube, then complex resonator in the chord crying musical instrument resonator vertically must be installed between epithelium and the qin bar, its length should be than short 3～4 millimeters of qin tube internal diameter, all keep some gaps with qin tube plate and epithelium, qin bar before and after reaching up and down after the installation, preceding air port 3 must be over against also close vibration source numeral place, adjustment installs and fixes the extension silk 4 of usefulness, and it can freely be trembleed by a small margin, can not play at great dynamics again to brush up against epithelium, qin bar, barrel when rocking and send noise.
The present invention is widely applicable, and various Chinese and Western bowed stringed instrument, plucked instrument all can and require with reference to above-mentioned installation method to implement.
Complex resonator in the chord crying musical instrument resonator of the present invention, simple structure is easily made, and easily installs, and invests economicly, and effect is remarkable.
