Abstract

The utility model relates to a modulation device for a Guzheng, which is arranged in a tuning box body on the rear or head part of the Guzheng, and is characterized in that: the modulation device comprises a tuner bracket, a chord nail, a turner, a tone indicator panel and a modulation calculator; wherein, the turner is composed of a worm gear, a worm and a knob; the chord nail is fixed on the side plate of the tuner bracket; the worm gear is arranged on the chord nail; the worm is fixed on the tuner bracket and is upwards vertical to the chord nail; the worm rotates to drive the worm gear and the chord nail to rotate; the knob is arranged on the upper end of the worm; the tone indicator panel is arranged under the knob; and the modulation calculator is fixed on the side plate of the turner bracket. A Guzheng player can manually turn the tuning knob to change the tensile force of the chord according to the rotation angle of the tone indicator panel, the difference relationship of the pitch and pitch interval of the chords is accordingly changed, and the arbitrary modulation of 12 musical modes is realized.

Description

A kind of modulation device of Zheng

Technical field

The utility model relates to the modulation device of musical instrument, relates in particular to a kind of modulation device of Zheng.

Background technology

Zheng is a kind of Chinese Musical Instruments.The overwhelming majority of Xiao Shouing is traditional Zheng of tuning up with five-tone scale in the market.This Zheng is adjusted to the basis with D and transfers, and covers an octave by 6 strings, has 21 strings, covers at least 4 octave.The modulation of this traditional Zheng can change the length of string by mobile qin sign indicating number, perhaps adjusts this dual mode of tension force of string and realizes.The tradition Zheng when transferring D to turn into other modes from the basis, needs the player to move 4 to 21 qin sign indicating numbers or rotates 4 to 21 qins nails with spanner in the process of playing music.This process is difficult to finish quickly and accurately.The difficulty of tradition Zheng modulation has limited Zheng institute energy playing music purpose type, and the application of Zheng in band.Present all kinds of modulation Zheng of selling on the design of disclosed various Zheng modulations and the market since physical construction too complicated, influence Zheng generation effect, change a variety of causes such as Zheng playing mode and characteristic, all do not accepted by Zheng performance circle.

The utility model content

Technical problem to be solved in the utility model provides a kind of modulation device of Zheng, has overcome the shortcoming of above-mentioned prior art.

Technical problem to be solved in the utility model is achieved through the following technical solutions:

A kind of modulation device of Zheng, described modulation device is arranged in the tuning casing of qin tail or scroll head, it is characterized in that: organ stop, tone display disc and modulation counter that described modulation device comprises organ stop support, string nail, is made up of turbine worm and knob; Described string nail is fixed on the side plate of organ stop support; Described turbine is arranged on the string nail; Described worm screw is fixed on the organ stop support, follows closely perpendicular to string upward; The rotation of described worm screw drives the rotation of turbine chord nail; Described knob is arranged on the upper end of worm screw; Described tone display disc is arranged on the below of knob; Described modulation counter is fixed on the side plate of organ stop support.Described modulation device also comprises tuning pilot lamp and the reference note pilot lamp by the control of modulation counter.

The employed organ stop of the utility model is a stringed musical instrument, for example guitar and urheen, general turbine worm combination, by the knob that has pointer, by changing the pitch that tension force changes string.The player uses the hand turning knob, rotates the string nail by the turbine and worm system, changes the tension force of string, changes the pitch of string, thereby realizes the tuning and the modulation of Zheng.

Rotatable tone display disc is set below the tuning knob, and according to basic tone, for example D transfers 21 strings is carried out after tuning finishes at Zheng, and rotation tone display disc makes it on the basis transfer, and for example D accent mark aligns with the pointer of tuning knob.

On the tone display disc, raise or when reducing the interval of a semitone and a whole sound, the angle of the required rotation of string button makes a mark for the tone of string.

When Zheng need change into other modes, the Zheng player is according to the rule of traditional Zheng modulation of tuning up by 5 sound rank, change the string of pitch for needs, with knob clockwise or be rotated counterclockwise, make the rotation of knob arrive on the tone display disc position of mark in advance,, make of the requirement of the pitch of string according to institute's modulation formula by changing the tension force of string, raise or reduce a semitone or a whole sound, thereby reach the purpose that transfers other modes to.

When needs change into other modes, determine to need change by the modulation counter pitch string number and change the degree of pitch, promptly need to raise or reduce the interval of a semitone or a whole sound, result of calculation is stored in the modulation counter.

Being arranged near the tuning pilot lamp of tuning knob is controlled by the modulation counter, be presented at the result of calculation of storing in the modulation counter, need rotate the number of tuning knob during for modulation, and this knob needs along clockwise or be rotated counterclockwise, and need rotation semitone interval or whole sound interval to show, so that prompting Zheng player carries out correct operation.

Under the string at Zheng Yue Shan place, be provided with the display lamp of root of each octave of modulation counter control, be used for showing the position of the pairing root of each mode of Zheng.Both 5 of music (sou) or other sounds positions of 1 (dou) for example is as the prompting to Zheng player playing music.

The utlity model has following advantage:

The utility model is that traditional Zheng designs a kind of additional modulation device, simple in structure, easy to operate, under the prerequisite of the structure that does not change traditional Zheng, tone color, tonequality, volume and playing method, the Zheng player rotates the tuning knob with hand, according to the prompting to rotational angle of tone display disc, by the tension force that changes string realize quick tuning and between 12 music modes arbitrarily, modulation quickly and accurately.
