CN201307398Y - Double-box bass zither - Google Patents

Abstract

The utility model discloses a double-box bass zither and belongs to the technical field of zithers. The zither comprises a hollow resonator consisting of a panel arranged on the upper part, a bottom plate arranged on the lower part, end plates arranged at both ends, a front side plate and a back side plate. Three sound beams are vertically arranged in the resonator at intervals; sound holes are formed on the bottom plate; a zither bridge is arranged on the panel; a plurality of zither strings with both ends being fixed on the resonator are arranged on the zither bridge; and the height of each of the side plates is 12 cm to 13 cm, and the diameter of the zither string is 1.0 cm to 3.0 cm. The utility model has the following advantages that the height of each of the side plates is increased, the corresponding resonator is increased in size and the natural vibration frequency of the resonator is increased; the diameter of the zither string is bigger in comparison with the prior zither string, so that the natural vibration frequency thereof is reduced; the resonator is combined with the zither string to produce sound with lower frequency; and the double-box bass zither can be combined with a normal zither for the playing, thereby making up the defects that the prior zither can not cover diapason with lower frequency. The double-box bass zither can be combined with the normal zither for the playing.

Description

Double-case bass Chinese zither

Technical field

The utility model relates to a kind of musical instrument, particularly a kind of Zheng.

Background technology

Zheng of the prior art, its structure mainly comprises the hollow resonant of being made up of the end plate at the base plate of the panel on top, bottom, two ends and front and back side plate, keep at a certain distance away in the resonant and uprightly be provided with three road sound beams, described base plate is provided with sound hole, outside the end plate on right side, be provided with zither head box, panel is provided with the zither horse, and zither sets up some two ends at once and is fixed on zither string on the resonant.The player stirs the zither string, the string vibration, and by sounding from sound hole after the resonant sympathetic response.Existing Zheng has specific range scope, can satisfy general bullet and gather, and its weak point is: the side plate height of existing Zheng is 8cm, its natural frequency is higher, zither string diameter is also less, makes it can not cover lower bass range, needs other basses to cooperate during (instrumental) ensemble and plays.

The utility model content

The purpose of this utility model provides a kind of double-case bass Chinese zither, makes Zheng can cover more low-frequency range scope, to satisfy the needs of instrumental ensembling.

The purpose of this utility model is achieved in that double-case bass Chinese zither, comprise by the panel on top, the base plate of bottom, the end plate at two ends and the hollow resonant that the front and back side plate is formed, keeping at a certain distance away in the resonant uprightly is provided with three road sound beams, and described base plate is provided with sound hole; Panel is provided with the zither horse, and zither sets up some two ends at once and is fixed on zither string on the resonant; The height of described side plate is 12-13cm, and zither string diameter is 1.0-3.0cm.

The utility model is increased side plate, and corresponding resonant strengthens, and its intrinsic vibration frequency is step-down also; The more existing zither string of zither string diameter diameter is thick, and the natural frequency when making its vibration is step-down also; Both cooperatively interact and can send the lower sound of frequency; Can instrumental ensemble with common Zheng, can not cover more low-frequency defective to remedy existing Zheng.This Zheng can be used for instrumental ensembling with common Zheng.

For making the Zheng sound can be longer, be provided with dividing plate in the described resonant, dividing plate is divided into two up and down with resonant, also is provided with sound hole on the described dividing plate.Resonant is divided into two parts up and down, and during sounding, sound wave agitates in resonant and repeatedly reflection, makes sound longer, and lingering sound is without cease.

For adapting to the variation of resonant, zither string natural frequency better, described zither horse highly is 8-9cm.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is A-A sectional drawing of Fig. 1.

Wherein, 1 zither head box, 2 panels, 3 zither strings, 4 sound beams, 5 zither horses, 6 sound holes, 7 dividing plates, 8 base plates, 9 side plates, 10 end plates.

Embodiment

As figure, double-case bass Chinese zither is made of resonant hollow zither head box 1, zither horse 5, zither string 3 and resonant, the base plate 8 of its panel 2 by top, bottom, the end plate 10 at two ends, front and back side plate 9 are formed, and keep at a certain distance away in the resonant and uprightly are provided with three road sound beams 4; 13 zither horses 5 are erected on the panel, and zither horse 5 highly is 8-9cm, and each zither horse 5 is put on the shelf and is provided with two ends and is fixed on zither string 3 on the resonant; The height of side plate 9 is 12-13cm, and zither string 3 diameters are 1.0-3.0cm; Be provided with dividing plate 7 in resonant, this dividing plate 7 is divided into two up and down with resonant, is equipped with sound hole 6 on base plate 8 and the dividing plate 7.

The utility model is not limited to the foregoing description, and described zither string number also can suitably reduce or increase.

Claims (4)

1, double-case bass Chinese zither comprises that keeping at a certain distance away in the resonant uprightly is provided with three road sound beams by the panel on top, the base plate of bottom, the end plate at two ends and the hollow resonant that the front and back side plate is formed, and described base plate is provided with sound hole; Panel is provided with the zither horse, and zither sets up some two ends at once and is fixed on zither string on the resonant; It is characterized in that: the height of described side plate is 12-13cm, and zither string diameter is 1.0-3.0cm.
