Abstract

The present invention announces a kind of percussion instrument " bell qin ",One kind copper alloy,It is semicircle,Like small bell (abbreviation small bell),Processed by casting,Change resonant frequency (tone),Tone color is adjusted by changing density,The lightness of pronunciation is improved by reducing resonant cavity damping,All small bells according to " twelve-tone equal temperament " rule,Combination,It is fixed on wooden qin frame,It is formed a kind of new musical instrument,For convenience of performance,The high bass two rows of scale point,Tone is from G4-B7 totally 41 scales,90 centimetres of this qin length,High 45 centimetres (not including support) each sounding body is connected using spring leaf,Hit with gavel,During performance small bell can resonate pronunciation and can swing up and down change pronunciation direction,Tone color is clear and melodious,It is bright,Narrate in a specious manner that moves one to listen,Can the happy happy psychotic mental of expression,Also new kind is increased for musical instrument circle.

Description

Bell qin

Technical field：

The present invention relates to musical instrument field, more particularly to percussion instrument.

Background technology：

In existing percussion instrument product, it can play that the copper musical instrument of melody is seldom, the fivebyfive of copper bell, which is listened, can not but play melody, and most of Ledu of hitting is the performance to rhythm, rather than the performance to music rhythm.

The content of the invention：

In order to overcome above-mentioned existing technical deficiency, the invention provides a kind of percussion instrument-bell qin that can play melody.

The present invention adopts the technical scheme that：According to acoustics resonance principle, sounding body referred to as (small bell) of the shape similar to copper small bell is passed through casting, machine tooling, change frequency of oscillation (tone) by changing its physical dimension, proportioning by changing copper alloy increases density and changes tonequality, the lightness that damping by reducing vibration chamber raises the tone, rule multiple sounding bodies with individual tone according to twelve-tone equal temperament, combination is fixed on four scale cross bar timberings, this qin is about 1 meter, tone is from G4--B7 totally 41 scales, it is divided into two rows for convenience of all scales of bell qin are played, hit with gavel.Compared with prior art, the beneficial effects of the invention are as follows：Dulcet sound is allowed to turn into the musical instrument that can be played, increase the kind to play an instrument, the less varieties that relatively existing percussion instrument can be played, tone color is limited, and the present invention uses the soft fixation of spring as a result of Cu alloy material on fixed structure, small bell while strike vibrations pronunciation through that can also swing up and down during performance, change the direction of sound, make tone color more clear and melodious melodized, can more express the requirement of happy happy emotion！The very convenient performance of this qin and study, it need not adjust tone, it is not required that as other orchestral bowings, fingering, with gas, as long as strike just can send pleasing to the ear metal sound, be easy to popularize and practise mastery learning music knowledge.

Brief description of the drawings：

A kind of percussion instrument-bell qin such as Fig. 1 combined by multiple sounding bodies of Fig. 1,1 carries handle, 2 be high pitch chromatic scale cross bar, 3 be high pitch whole tone scale cross bar, 4,5 be bass chromatic scale and whole tone scale cross bar, and 6 be bell qin support, and small bell is swung up and down after 7. elastic metallic materials, 8. semicircle sounding bodies, 9. strikes.

Embodiment

8 be by retrofit, the accurate tuner of instrument in each sounding body such as Fig. 1, frequency of oscillation is reached the requirement of twelve-tone equal temperament, such as c5, pronouncing frequency is 563.2 hertz.Copper alloy ratio is adjusted in terms of casting improves copper alloy density, it is allowed to send clear and melodious melodious, the strong tone color of bright sense, proofreaded in frequency of oscillation by CALIBRATION, relatively centre frequency, each note after mixing up is changeless, each sounding body and rack cross-bar 2, 3, 4, 5, (7 in Fig. 1) are all combined using elastomeric material, physical efficiency of pronouncing during strike, which swings up and down in Fig. 19 and had, shakes sympathetic response and has upper and lower air swaying direction sound again, so it is very lucid and lively lively to play musical note out, sound very graceful interesting to listen to, this qin length is about 1 meter high by 45, this is table qin, it can also make vertical or hanging.

Claims (3)

1. a kind of tinkling of pieces of jade qin, by timbering, scale cross bar, semi-circular sounding body referred to as " small bell " forms, it is characterized in that：Each small bell of the musical instrument has the spring leaf (7) of fixed pronouncing frequency (8) and scale cross bar (2,3,4,5) and fixed small bell.

2.According to claimTinkling of pieces of jade qin described in 1 it is characterized in that：Scale cross bar is respectively high pitch chromatic scale (2), and high pitch whole tone scale (3), bass chromatic scale (4), bass whole tone scale (5) structure is to be arranged above and below.The above is high pitch, and here is bass.Tone from left to right raises successively.

3.According to claimTinkling of pieces of jade qin described in 1 it is characterized in that：All small bell and scale cross bar connections are all using elastomeric material (7) (small bell can swing up and down (9) and sound more lively melodious during performance).
