CN201812479U - Alto Chinese violin easy for vibrato and capable of beautifying timbre - Google Patents

Abstract

The utility model discloses an alto Chinese violin easy for vibrato and capable of beautifying timbre. The alto Chinese violin is characterized in that a stem is arranged on a drum, a shaft is arranged on the upper portion of the stem, strings are connected between the shaft and a support on the lower portion of the drum, a bridge is arranged on the drum, a jack and a vibration jack are arranged on the stem, a small bearing of the vibration jack is arranged on the stem, a fastening press stem is rotatably connected onto the bearing, and a spring is arranged between the fastening press stem and the stem. Hands feel looser for the strings by the aid of the vibration jack and elasticity of the spring, consequentially, difficulty for vibrato is evidently lowered, a user not only can easily vibrate the alto Chinese violin in a pressing manner, but also can normally vibrate in a rolling manner, and a traditional alto Chinese violin playing method and skills are not changed. Movable stems of the fastening press stem adopt a drawing type, so that convenient and flexible variation of the position for tone setting by means of tuning up the strings can be easier to be realized, and the alto Chinese violin is convenient for children, adults and the like. The spring is arranged in the vibration jack and vibrates along with vibration of the strings, namely, new vibration is added to the alto Chinese violin without changing fundamental frequencies of the strings, so that the timbre is more graceful, and improvement of the timbre is more outstanding especially in open-string playing.

Description

Hu in a kind of middle pitch that is easy to rub string, beautify tone color

Technical field

The utility model relates to a kind of national musical instruments, Hu in especially a kind of middle pitch that is easy to rub string, beautify tone color.

Background technology

In be recklessly in the traditional instruments orchestra in the important bowed instrument of part, be again the solo musical instrument simultaneously.And middle Hu can be divided in the high pitch recklessly, in the bass recklessly, in the middle pitch recklessly, the utility model be in traditional middle pitch recklessly.The structure of Hu is to be provided with the qin bar on the qin tube in the middle pitch, is provided with the qin axle on the top of qin bar, is connected to string between the qin holder of qin axle and qin tube bottom, and the qin skin is provided with the qin sign indicating number; On the qin bar, also be provided with very heavy (the claiming a thousand pieces of gold again) of string being played fixing and chord of contact effect.Hu utilizes the friction between bow and the string to drive the string vibration when playing in the middle pitch, and string encourages the vibration of qin skin by the qin sign indicating number, empathizes in the qin tube, thereby produces sound.

The Chinese fiddle bar is long than urheen in the middle pitch, refers to a wider distribution, and the most suitable performance is vast unfolds, the melody of long figure and the property sung.Thereby, rub the string skill and seem particularly important.It is very heavy that Hu Yizhi uses traditional rope bundle formula (or gold belongs to the Hook formula) in the existing middle pitch, by string vibration frequency formula (I) as can be known,

$f=\frac{n}{2l}\sqrt{\frac{T}{\mathrm{\ρ}}}---\left(I\right)$

Reserve in the middle pitch of accent recklessly that l, ρ are certain, rub in the string change to frequency and be mainly derived from pressure (changing tension force T) and the rolling (change l) of finger tripe on string string.But because the Chinese fiddle string is generally thick than urheen string in the middle pitch, people often feel that when rubbing string its string is very hard.Promptly imposing when rubbing the string skill, do not impose enough pressure, string distortion or bending are very little, and the wave amplitude that causes is not enough.Beginner particularly, the amplitude of rubbing string more is difficult to guarantee.

The utility model content

The technical problems to be solved in the utility model provides in a kind of middle pitch that is easy to rub string, beautify tone color of easier realization tumbling recklessly.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: be provided with the qin bar on the qin tube, be provided with the qin axle on the top of qin bar, be connected to string between the qin holder of qin axle and qin tube bottom, the qin skin of qin tube is provided with the qin sign indicating number; Be provided with very heavyly on the qin bar, its improvements are, it is very heavy also to be provided with vibration on the qin bar; Described vibration is very heavy to be to be provided with little bearing on the qin bar, on little bearing, be rotatably connected to and withhold bar, withhold bar and and the qin bar between be provided with spring.

The further technical scheme of the utility model: very heavyly move 4-10cm from traditional very heavy position, vibrate very heavy withholding a little be positioned at very heavy below.

The utility model preferably withhold bar be the top switching of two motion bars on little bearing, two motion bars adopt the drawing and pulling type structures, lay respectively at the both sides of string; Described spring is connected the middle part or the middle front part of motion bar; Be provided with two depression bars that motion bar is affixed in the lower end of motion bar, depression bar is withheld string under the pulling force effect of spring.

The further technical scheme of the utility model is the spring regulating device that is provided with the adjustable springs degree of tightness between qin bar and spring.

The structure of preferred spring regulating device is: be with the adjuster bar of U-shaped on the qin bar, two ends of adjuster bar run through adjustable plate, and spring is fixed on the adjustable plate; Two ends of adjuster bar are provided with screw thread, by the location of nut and screw thread realization adjuster bar and adjustable plate.

Adopt the beneficial effect that technique scheme produced to be: the utility model is very heavy by vibration is set on the Hu in middle pitch, originally fixing very heavy moved on suitably, make the feel of player when playing become more lax, so just significantly reduced the difficulty of rubbing string, not only kneadding easily can also easily realize the string of rubbing of normal tumbling and nip drum convolution.Owing to be provided with spring during vibration is very heavy, spring can vibrate with vibrations of strings, i.e. the utility model new vibration that under the constant situation of the fundamental frequency of string, superposeed, and this just makes tone color of the present utility model more soft and graceful, especially when empty string was played, the improvement of tone color was more outstanding.

Especially vibrate very heavy motion bar and adopt the drawing and pulling type structure, the length that the player can withhold bar according to the hand-type size adjustment of oneself, change the very heavy chord of contact position of vibration, all can be convenient and practical to juvenile, adult etc., and to traditional playing technique and method without any change.

When especially the utility model was set up spring regulating device, the degree of tightness of regulating spring was vibrated very heavy good chord of contact accordatura to realize this, so that the utility model is applicable to different performance situations as required.
