The utility model adds tamber to the middle and the bass registers of the national instrument provided with the basic performing means of music and efficiently increases the expressive force of music. The utility model has the advantages of simple structure, easy carrying, low manufacturing cost, easy learning compared with stringed instruments and other plucking instruments and high prevalence rate. The utility model has a plurality of grades of the big, middle, small, high, middle and low with various specifications applicable, therefore meets the demands of solos, accompaniments, band concerts and entertainments.

Description

The national musical instruments that a kind of both hands are played

1, technical field the utility model relates to a kind of national plucked instrument, specifically relates to the national musical instruments that a kind of both hands are played.

2, the present national plucked instrument of technical background, as Chinese lute, liuqin, Ruan, bullet cloth etc., and it is similar, external plucked instrument has guitar etc., and similar structures, and their common ground is vibrating mass with the string, the strong point is 2 points, middle vibratory drive resonant tank is played music score and is referred to that with left hand 4 right hand is played string.

Could produce desirable tone color and mode after though the string tension of plucked instrument is tight, big to audio amplifier (skin) pressure, destruction is arranged when especially air humidity and dry difference are big, accuracy in pitch poor effect, easily out of tune, the beginner sets the tone than difficulty etc.

The musical expression of plucked instrument, existing kind is far from reaching the required optimal music expressive forces of occasion such as music appreciating, song and dance, opera, drama, movie and television play.

3, the summary of the invention the purpose of this utility model is the national musical instruments that provide a kind of both hands to play for national musical instruments, and for middle basso increases tone color, but both hands ten fingers are played note respectively, increase the expressive force of music effectively.It is simple in structure, low cost of manufacture, easy to carry, than stringed musical instrument and other plucked instruments are easily learned, popularity rate is high characteristics etc.

For achieving the above object, the technical solution of the utility model is achieved in that the qin sign indicating number is fixed on the Loudspeaker panel middle part, and each dull and stereotyped strip sounding body is clamped on the qin sign indicating number, and sounding body is with metal and high strength plastics and high resiliency.Because sounding body coverlet fulcrum supports, so there is not tensile force, audio amplifier does not bear pressure, and is not out of tune when the humidity difference is big.Play the tone that sends and adopt the ordering of twelve-tone equal temperament system, both hands ten refer to play out simultaneously skills such as melody and sound accompaniment, harmony, chord, and the conversion tone is convenient.

4, description of drawings Fig. 1 is a both hands plucked instrument vertical view.Fig. 2 is the A-A sectional view (its ratio Fig. 1 amplifies 3 times) of Fig. 1.Fig. 3 is the vertical view of B-B among Fig. 2.

5, embodiment will be described in detail embodiment of the present utility model with reference to accompanying drawing.

Structure of the present utility model is: the qin sign indicating number [4] that materials such as hardwood are made can distinguish independent form or whole crosswise fixed at Loudspeaker panel [5] middle part, each dull and stereotyped strip sounding body [3] is tightened gland [2] formation jaw by bolt [1] respectively and is clamped on the qin sign indicating number [4], qin sign indicating number [4] is born the nut effect, sounding body [3] is supported by the single fulcrum of qin sign indicating number [4], audio amplifier [6] does not bear pressure, accuracy in pitch is effective, but and loose bolts [1] regulate the distance adjustment pitch (sounding body [3] of making standard pitch can not need tuning) that sounding body [3] stretches out.Determining of tone: sounding body [3] is that C transfers middle pitch arrangement central authorities, with the length of CALIBRATION C adjustment to decision sounding body [3], left side bass, the twelve-tone equal temperament system of employing, the clamped part pros and cons of sounding body [3] has ironed netted decorative pattern [8], displacement is out of tune when stoping vibration, and sounding body [3] material requested is that the performance of pronunciation when having high resiliency and hardness and body vibration such as metal and high strength plastics is as sound source medium (material).

The part basic size that sounding body [3] exposes, length: bass 300.0mm gradually is as short as high pitch 20.0mm, width: bass 6.0～30.0mm is gradually narrow to high pitch 2.0mm～9.0mm, thickness: bass 1.0mm～2.5mm gradually is as thin as high pitch 0.2mm～0.3mm.The cross section is selected difform geometric surface for use according to tone color and intensity, the end [7] of sounding body [3] is semicircle, distance from Loudspeaker panel [5]: bass 30.0～50.0mm gradually is low to moderate high pitch 20.0mm～30.0mm, and the centre distance of sounding body [3] is 16.0mm～21.0mm and 18.0mm～35.0mm.

The utility model can be made large, medium and small, the multiple model of high, medium and low class, 60,39,27 of quantity of sounding body [3] configuration can be provided with on demand, and its audio amplifier [6] overall size is 1200.0mm*350.0mm*80.0mm, 850.0mm*280.0mm*60.0mm, 720.0mm*240.0mm*55.0mm.

When playing qin is lain on the folding rack that can heighten with qin, between audio amplifier [6] and the support by cork or 3 contact points of rubber cushion, sitting posture, standing gets final product, both hands ten refer to play note respectively, nail and finger abdomen can encase with adhesive plaster, wear-resisting, because of the people decided because of the time of playing, firmly clicking sounding body [3] fast is subjected to driving force to be used as the sympathetic response of convergent oscillation driving audio amplifier [6], send the abundant musical sound of wooden deepness, bass in the genus can be played out skills such as melody and accompaniment part, harmony, chord simultaneously, possesses the basic expression means of music.
