Abstract

The utility model provides a compounded resonance barrel of a musical instrument, which is composed of an inner barrel, musical instrument skin, a sound window, etc. The utility model is characterized in that a polygonal outer barrel is arranged on the periphery of the inner barrel to form a barrel of the musical instrument, which is provided with a double-layer compounded resonance body. The barrel of the musical instrument solves the defect that only a single cavity body of the inner barrel is arranged so that the utility model can be adapted to the resonance requirement of sound amplification, and the aims of volume expansion and timbre beautification are achieved.

Description

Compound sympathetic response qin tube

The utility model relates to national musical instruments, particularly a kind of compound sympathetic response qin tube.

At present, national stringed instrument that China is popular such as urheen, high Hu, jinghu, bowed stringed instrument with a thin wooden soundboard, coconut palm recklessly etc., the qin tube that is adopted all is to make housing with materials such as wooden, thick bamboo tube or coconut husks, covers with Qin Pi or panel and sound window and makes resonating body (qin tube).Though these qin tubes are different, materials differ, and it all has strong and dense national style and color on aspect moulding and the pronunciation, and have volume little, give great volume, characteristics such as tone color diversification.Therefore, be widely used with popular among the people.But, because pandemic these common bowed instruments all are the musical instruments that has only two strings.And common qin tube also can only be fit to assemble the bowed instrument that has only two strings because its structure is limit, if in case when meeting the high pitch that exceeds two strings or bass and taking place, common qin tube just is difficult to adaptation.It is dried, hard, narrow, little that the sound that is sent will become, and sounds not nature.So, seek a kind of novel qin tube and solve this difficult problem.

The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of sympathetic response sound of qin tube that makes further to strengthen, expand, and realizes beautifying the purpose of tone color.

The purpose of this utility model is achieved by the following scheme, constitute by inner core, qin skin, sound window and string bolt seat, its solution is to be provided with the polygon urceolus in the periphery of inner core, this urceolus can constitute polygon with the wood chip that polylith shapes, and can constitute polygon by the monoblock wood working simultaneously.

The utility model has following advantage compared with the prior art: the double-deck qin tube of compound formation is more mellow and fuller, simple and honest than the pronunciation of individual layer qin tube, especially is fit to be applied to through adding the bowed instrument of string reform.Reform the pressure increase of back to the qin skin because of musical instrument through adding string, add reasons such as bridge increase, pronunciation will diminish comparatively speaking, but adds the stringed musical instrument range than original broadness, and common qin tube just difficulty adapts to.The utility model efficiently solves this difficult problem, makes the national stringed instrument voice effect that adds string reach hard and soft mutual Ji, and existing loud and sonorous bright high pitch has simple simple and honest bass again.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is a Facad structure synoptic diagram of the present utility model;

Fig. 2 looks synoptic diagram for the right side of Fig. 1;

Fig. 3 looks synoptic diagram for the left side of Fig. 1.

As shown in Figure 1-Figure 3: constitute two-layer compound sympathetic response qin tube jointly by inner core 1, urceolus 2, qin skin 3, sound window 4, string bolt seat 5, qin holder 6, pressure regulating seat 7.

Embodiment is: inner core 1 and qin skin 3 (or panel) tightly are bonded together constitutes the resonant tank main part earlier, will be sleeved on the periphery of inner core 1 with the urceolus 2 that wood materials shapes again, forms a qin tube with two-layer compound resonant.This qin tube does not have differently greatly from producing the qin tube see with common sound layer structure in appearance, but volume and sympathetic response Space are further strengthened, expanded than common qin tube.Thereby changed the deficiency of having only the single cavity of inner core greatly, made it to adapt to more the sympathetic response needs that amplify, reached the expansion volume, beautified the purpose of tone color.

Claims

1, a kind of compound sympathetic response qin tube is made of inner core (1), qin skin (3), sound window (4) and the combinations such as (5) of string bolt seat, and it is characterized in that: the periphery that is positioned at inner core (1) is provided with polygon urceolus (2).

2, qin tube according to claim 1 is characterized in that: said urceolus (2) constitutes polygon by the wood chip that polylith shapes.

3, qin tube according to claim 1 and 2 is characterized in that: said urceolus (2) constitutes polygon by the monoblock wood working.
