Abstract

The utility model discloses a convex arch shaped membrane Erhu with side acoustic window comprising a resonance box. A neck is provided on the resonance box, a membrane is provided on the front end of the resonance box, and an acoustic window is provided on the rear end. The Erhu is characterized in that a convex arch shaped membrane is provided on the front end of the resonance box, one to plural side acoustic windows in different sizes are added, high, medium, low frequencies are sent out through duct of their own based on the length, so that the deficit of noise which is hard to be overcome is eliminated. The resonance box of the Erhu is more beautiful in appearance, and more practical, the Erhu acoustic membrane is more elastic, the sounding in high pitch level is louder, the volume is higher, the acoustic range is wider, the voice penetration is stronger, the timbre of the nasal sound is more elegant, the performance can be conducted.

Description

A kind of convex surface arc sound film urheen with the sidetone window

Technical field

The utility model relates to a kind of national musical instruments, specifically, relates to a kind of convex surface arc sound film urheen with the sidetone window.

Background technology

At present, traditional urheen tune is that the hand push hair of pulling the bow acts on string, the surface sound film of resonant tank sends sound wave, sound wave is sounded by the sound window of urheen resonant tank, its structure is that a resonant tank has a sound window, this urheen sends from a qin window owing to high, normal, basic frequency sound wave is concentrated, the defective that causes noisy sound to be difficult to overcome, this urheen is also because the sound film is pure flat, easily weakened and follow the string by the compacting of qin sign indicating number, cause the high position sounding not work, the sound penetration power is not strong, can not pull for a long time to enter playing state.

Summary of the invention

The utility model provides a kind of high position louder, and the sound penetration power is stronger, can enter playing state, a kind of convex surface arc sound film urheen with the sidetone window that tone color is graceful more.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of urheen of the convex surface arc sound film with the sidetone window, comprise resonant tank, be set with the qin bar on the described resonant tank, the qin bar passes the jack of resonant tank, it is characterized in that: described resonant tank is provided with convex surface arc sound film and several sidetone windows that vary in size.

Beneficial effect:

The utility model adopts the scheme of going up, sound window of traditional urheen resonant tank and surface sound film are transformed, the front end of resonant tank is provided with convex surface arc sound film, increase by a sidetone window to several different sizes, high, normal, basic equifrequent sound wave is respectively sought Qi Dao according to length and is led off and send, thereby eliminated this defective that is difficult to overcome of noisy sound, the urheen resonant tank is more both artistic and practical, make the high resilience of urheen sound film, the high position sounding is louder, and volume is bigger, range is broader, the sound penetration power is stronger, and the nasal sound tone color is graceful more, can play.

The vertical view of Fig. 4 the utility model resonant tank.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment

Embodiment, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of convex surface arc sound film urheen with the sidetone window, comprise resonant tank 3, be set with qin bar 5 on the described resonant tank 3, the front end of described resonant tank 3 is provided with convex surface arc sound film 4, the rear end is provided with sound window 2, casing on the described resonant tank 3 is provided with the sidetone window 1 of several different sizes, resonant tank 3 is passed by jack 6 in qin bar 5 lower ends, the push-and-pull bow makes convex surface arc sound film 4 produce the vibrations sound waves, sound wave through the sidetone windows 1 of different sizes and after sound window 2 passage sounding.

Claims

1. urheen with the convex surface arc sound film of sidetone window, comprise resonant tank (3), be set with qin bar (5) on the described resonant tank (3), qin bar (5) passes the jack (6) of resonant tank (3), it is characterized in that: (3) are provided with convex surface arc sound film (4) and several sidetone windows (1) that varies in size on the described resonant tank.
