Abstract

The utility model relates to a portable Koto, which comprises a panel, a bottom plate, a side plate, a Koto head, a Koto tail, a takeyama, a Koto code and a Koto string, wherein, the panel, the bottom plate, the side plate and the Koto tail form a resonance box, a tone bridge is arranged in the resonance box, a sound output hole is arranged on the bottom plate, and Koto nails are arranged in the Koto head. The utility model is characterized in that the panel is an arched plate, the middle part of the panel is thick, and the circumference of the panel is thin. The length of a resonance box body is 60-90 cm, and 13-15 pieces of Koto strings are arranged. The utility model has the advantages of portability and strong recreation. The utility model is suitable for being used as a musical instrument for learning purpose by infants, children and schools.

Description

Portable Zheng

The utility model relates to a kind of bullet and pulls out stringed musical instrument, specifically a kind of portable Zheng.

Zheng is one of traditional outstanding national musical instruments of China, its tone color grace, elegance, and the mild and roundabout smoothness of harmonious sounds, it is quick-moving, the ABC of easily that study gets up to go up; At present, the kind of Zheng is a lot, the branch that traditional zheng and reform zither are arranged, but its structure is similar, mainly by panel, base plate, side plate, zither head, zither tail, Yue Shan, numeral, qin nail, sender and zither string etc. are partly formed, and wherein resonant tank is formed on the panel of Zheng, base plate and two zither limits, be provided with the sound bridge in the resonant tank, the Zheng base plate is provided with sender; Its deficiency is: the zither body of Zheng is generally long, be not suitable as the study qin of child, children and school on the one hand, when out on tours, carry inconvenience on the other hand, this just makes Zheng limited to aspect exercise, performance and the amusement, be not easy to popularize, as geometric ratio simply Zheng is dwindled, then volume and tone color all can reduce greatly, influence exercise and playing effect.

The purpose of this utility model is to provide a kind of zither body little and lack, and is easy to carry, and give great volume, tonequality is pure, good tone color, play the portable Zheng in labour-saving.

The utility model is achieved through the following technical solutions:

The utility model comprises panel, base plate, side plate, zither head, zither tail, Yue Shan, zither sign indicating number and zither string, wherein panel, base plate, side plate and zither tail constitute resonant tank, in resonant tank, be provided with the sound bridge, on base plate, be provided with sender, be provided with the qin nail in the zither head, be characterized in that described panel is thick middle, thin cambered plate all around, the length of described resonant tank is 60-90 centimetre, and described zither string is the 13-15 root.

Characteristics of the present utility model are: 1) because Zheng belongs to plate resonance musical instrument, its tonequality quality is not only relevant with the structure of timber and physics, machinery, acoustical behavior, more relevant with the thickness distribution of plate, because the amplitude of panel vibration and the thickness that the frequency size is decided by panel: panel is thin more, amplitude is big more, and frequency is low more; Plate is thick more, and amplitude is more little, and frequency is high more, and the structure that panel adopts thick middle, approaches all around, its pronunciation characteristic is that pronunciation is pure and real; Give great volume so the utlity model has, tonequality is pure, and the mellow and full grace of tone color is played characteristics such as laborsaving, pronunciation sensitivity.

2) because the natural frequency of resonant tank of the present utility model is close with alt frequency, strengthened the sympathetic response effect of zither, the utility model is being further enhanced aspect volume and the tonequality.

3) the utility model volume is small and light, relatively is fit to child, children and school and uses qin as study, also is easy to carry when out on tours in addition, has increased the recreational of Zheng, makes that Zheng is easier to be popularized.

Described in detail below in conjunction with the utility model embodiment accompanying drawing:

Fig. 1 is the utility model embodiment stereographic map;

Fig. 2 is the utility model example structure synoptic diagram;

Fig. 3 is the A-A cut-open view of Fig. 2.

With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises panel 1, base plate 2, side plate 3, zither head 4, zither tail 5, Yue Shan 7, zither sign indicating number 8 and zither string 10, wherein panel 1, base plate 2, side plate 3 and zither tail 5 constitute resonant tank 6, in resonant tank 6, be provided with the sound bridge, on base plate 2, be provided with sender 12, be provided with qin nail 9 in the zither head 4, one end of zither string 10 is fixed on the zither tail 5, the other end is fixed in qin and nails on, be characterized in that described panel 1 is thick middle, thin cambered plate all around, the length of described resonant tank 6 is 65-80 centimetre, and described zither string is 13, and range is three octave.

For making tonequality of the present utility model better, described sound bridge is made up of many sound columns 11.Except that but counter plate 1 is played a supporting role, also can strengthen the sympathetic response effect of resonant tank, improve volume and tonequality.
