Description

A kind of Erhu

Technical field

The utility model belongs to musical instrument technical field, is specially a kind of Erhu.

Background technology

Urheen is the extremely wide bowed instrument of China's folklore, is the pillar in national instrument of China, there is long go through History.Its interior string tone color is soft, plentiful, and exterior string tone color is relatively bright, energetic.Urheen suitably plays soft careful lyricism rotation Rule, energetic strong or active cheerful and light-hearted melody can be also played by some special playing techniques, moreover it is possible to simulate the sound of drums and gongs, neigh, Chirping of birds, horse ululation etc., are the extremely abundant solo instruments of an expressive force.

Current existing structure of erhu includes piano stick, the barrel arranged on piano stick bottom, the base arranged on barrel bottom, is arranged on Axle that a pair on piano stick top is arranged above and below, be connected to two a pair of of strings between axle and base, and barrel is at it The front end face adjacent with string is equipped with qin film and bridge, and bridge is pressed on the outer surface of qin film by string.Drawn when with bow When dynamic string, the vibration of string is delivered on qin film by bridge, the sound that string vibration produces is passed through qin film and qin Cylinder zooms into the sound of larger volume.This existing urheen has the following disadvantages：1. barrel combines structure by several blocks of plates Into there are the deficiency of globality poor in its structure, junction easily allows sound to produce flaw, wolf sound, Sha Yin, miscellaneous easily occurs Sound；2. for sound wave directly by the cavity of barrel, its resonating effect is limited, exhale sound small and miscellaneous, cause tonequality is undesirable, volume is small to lack Weary vibration sense；3. qin film is installed in barrel, the fixed of qin film is operated by rule of thumb by stringed-instrument player processed, once be made, qin film it is elastic Degree cannot adjust, and the tone color of urheen also finalizes the design almost, and the quality of its tone color has great contingency, and by the shadow of temperature humidity Ring, qin film can fluff or become tight, and one has surprising difference urheen in different weather, different geographical its sounding, and existing urheen has Significant limitation；4. barrel is made of natural timber, natural environment, weather, soil when the quality of timber can be grown The various factors such as earth, species influence its property of pronouncing, and have the missing that the quality produced is difficult to stability contorting.Again because of the West Wind instrument is largely made of metal material, also there is the sound property of metal in terms of sound, when the player of the urheen is intended to and west When foreign wind instrument collocation is played, have and be not suitable for the missing that collocation western wind instrument is played.

The content of the invention

In order to solve the deficiencies in the prior art, the utility model provides a kind of Erhu.

Technical solution is used by the utility model：A kind of Erhu, including piano stick, barrel, qin film, base, qin Axis, string, bridge, a thousand pieces of gold, bow, wherein piano stick bottom are arranged in barrel, and base is set below barrel, and barrel front end is set Qin film, piano stick top set a pair of axle being arranged above and below, and a pair of of string are set between axle and base, between string and qin film Bridge is set, a thousand pieces of gold is equipped between string and piano stick top, it is characterized in that：The barrel includes outer barrel and inner cylinder, outer barrel and interior Cylinder is integrally formed by aluminium alloy compression casting；The outer barrel is the hollow circular cylinder of both ends open, and outer barrel rear open end is equipped with sound window, Outer barrel forward open end is equipped with circle and covers, and circle set is connected with outer barrel by screw thread, and circle is put on equipped with qin film；The inner cylinder is opened for both ends The hollow cone cylinder body of mouth, inner cylinder big opening end overall diameter are equal to the interior diameter of outer barrel, and inner cylinder osculum end overall diameter is slightly smaller than outer barrel Interior diameter, is uniformly provided with some open-works on inner cylinder side wall, by inner cylinder be arranged on outer barrel it is hollow in, make inner cylinder coaxial with outer barrel, it is interior Cylinder big opening end is fixedly connected towards outer tube rear end and with outer tube inner wall, and inner cylinder osculum end is towards outer cylinder front end and stretches out outer barrel port Qin film is supported, qin film is in outwardly convex shape under the counter-active effect of inner cylinder osculum end, screws the adjustable qin film elasticity of circle set.

Further, the outer cylinder front end is equipped with external screw thread, and circle is arranged with the internal thread to match with the external screw thread, circle set with Outer barrel is connected by screw thread, and circle set lateral surface is equipped with anti-skid chequer.

Further, in order to increase the stability of urheen, the center of gravity of urheen is reduced, iron block is equipped with the middle part of the base.

Further, in order to increase the stability of inner cylinder, in order to form multiple resonators, the outer tube inner wall and inner tank theca Between be uniformly arranged some support plates.

The utility model beneficial effect is：1. outer barrel, inner cylinder, support plate, open-work form multiple resonators, during performance, Sound wave is sent from after barrel front port enters multiple resonators by barrel sound window, and due to the effect of resonator, sound wave stacking is turned over Roll, sonorant is big, breaks out loudness of a sound, cry greatly and becomes clear, tonequality is good, tone color becomes clear, and it is easy to solve traditional urheen well There is the problem of wolf sound, Sha Yin, noise.2. screwing the adjustable qin film elasticity of circle set, it is difficult to stability contorting when overcoming manufacture Missing, reduce environmental factor on urheen tone color influence, meet different demands under different occasions；3. iron block is housed in the middle part of base, The position of centre of gravity of urheen is greatly reduced, player is clearly felt that qin lower part than scroll head portion's weight, has very strong stabilization Property；4. barrel includes outer barrel and inner cylinder, outer barrel and inner cylinder are integrally formed by aluminium alloy compression casting, therefore it is pure to improve sound Degree, manufacturer can control it to manufacture stay in grade, tonequality from the sound of weather influences, urheen is big and smooth-going and looks good with Western wind instrument is played.
