Abstract

Provided is a cylinder ponticello dual-membrane-surface Erhu capable of increasing the acoustic performance thereof. The Erhu has main characteristics that an inner cylinder equipped with a leather membrane is installed in an outer cylinder and on a same axis of the outer cylinder, that a sound chamber opened to the outer cylinder is formed between the leather membrane of the inner cylinder and that of the outer cylinder and is used as a main constituent part of a resonant body, and that the vibration of strings is conducted to the resonant body via a ponticello so that the Erhu emits sound similar to human voice.

Description

Sleeve, cover code, two face urheen
Affiliated technical field
The utility model relates to a kind of improved device of urheen, especially can improve the two face urheens of jacket casing code of urheen acoustics performance.
Background technology
Play at present traditional urheen resonant (single qin cylinder) simple structure of using, acoustical behavior is poor, and tonequality, tone color decay and wolf sound, noise easily occur in treble.Existing double-cylinder type improved ErHu also fails to solve the problem of above existence.
Utility model content
The purpose of this utility model is the two face urheen devices of jacket casing code that a kind of improvement will be provided, and it can alleviate the decay of urheen treble tonequality, tone color effectively, reduces wolf sound, noise, improves the acoustical behavior of urheen.
Technical solution adopted in the utility model is: on the inner same axis of qin cylinder (hereinafter referred to as outer qin cylinder), install one with the interior qin cylinder of epithelium, form outside qin cylinder open " sound chamber " between interior qin cylinder epithelium and outer qin cylinder epithelium.Outer qin cylinder and outer qin cylinder epithelium, interior qin cylinder and interior qin cylinder epithelium, sound chamber form resonant jointly.When the inside and outside string of bow friction of motion produces string vibration, string vibration conducts to inside and outside qin cylinder face by the cover code through outer qin cylinder epithelium, expands vibration, makes resonant send the sound.
The utility model only needs in qin cylinder, an interior qin cylinder with epithelium to be installed outside, and the cover code that passes outer qin cylinder epithelium, and string conduct vibrations, to resonant, is formed to chorus sound equipment, and structure is simple especially.Its starting point is with apery body vocal organs larynx vocal structures (vestibular Bi, Hilton's sac, sound wall)---" sound chamber ", and the decay that alleviates urheen treble tonequality, tone color reduces wolf sound and noise, makes it send the sound equipment of person of modern times's sound.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is according to the front view of the jacket casing code bimodulus face urheen device the utility model proposes.
1. outer qin cylinders in figure, 2. interior qin cylinder, 3. interior qin cylinder epithelium, 4. outer qin cylinder epithelium ,5. sound chamber, 6. interior qin corner brace, 7. outer bridge, 8. bridge cover plate, 9. outer bridge hole, 10. outer qin cylinder epithelium hole.
Embodiment
This device comprises an outer qin cylinder (1), be arranged on the interior qin cylinder (2) on same axis, between interior qin cylinder epithelium (3) and outer qin cylinder epithelium (4), form a sound chamber (5) that outside qin cylinder is open, when the inside and outside string of bow friction of motion, the vibration of generation string, string vibration is passed through bridge cover plate (8) and is passed the interior qin corner brace (6) of outer qin cylinder epithelium hole (10), outer bridge hole (9) to bridge cover plate (8) below, outer bridge (7) conducts to interior qin cylinder epithelium (3), outer qin cylinder epithelium (4) expands vibration, makes resonant send sound equipment.

Claims (3)

1. sleeve, cover code, two face urheen, this device has an outer qin cylinder (1) and is arranged on the interior qin cylinder (2) on same axis, it is characterized in that having formed between interior qin cylinder epithelium (3) and outer qin cylinder epithelium (4) sound chamber (5) of an outside qin cylinder opening.
2. sleeve according to claim 1, cover code, two face urheen, is characterized in that sound chamber (5) and outer qin cylinder (1) and outer qin cylinder epithelium (4), and interior qin cylinder (2) and interior qin cylinder epithelium (3) form resonant.
3. sleeve according to claim 1, cover code, two face urheen, interior qin cylinder epithelium (3) is with adjacent through the interior qin corner brace (6) in outer qin cylinder epithelium hole (10), outer bridge hole (9), outer qin cylinder epithelium (4) is adjacent with outer bridge (7), interior qin corner brace (6) top, outer bridge top (7) and bridge cover plate (8) are adjacent, and bridge cover plate (8) makes resonant and sounding by string conduct vibrations to interior qin corner brace (6), outer bridge (7).
