Description

A kind of automatic tuning and modulation device of Zheng

Technical field

The utility model relates to the tuning and the modulation device of musical instrument, relates in particular to a kind of automatic tuning and 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.Since the restriction of the wooden structures intensity of Zheng, movable qin sign indicating number, extension string mode, the influence of playing string when the tone of the string of traditional Zheng is subjected to environment temperature, humidity and performance.Be easy to change.Zheng often need carry out tuning before each the performance, perhaps play the tuning before of every first melody before the lights.Among the carrying out of a first melody, the accordatura of string also may change, and influences performing effect.For these problems, traditional Zheng does not still have solution.

The modulation of tradition 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.All kinds of modulation Zheng of selling on the design of present disclosed various Zheng modulations and the market, because physical construction is too complicated, influence a variety of causes such as Zheng generation effect, change Zheng playing mode and characteristic, all do not played the boundary by Zheng and accept, influence power is very limited.

The utility model content

Technical problem to be solved in the utility model provides a kind of automatic tuning and 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 automatic tuning and modulation device of Zheng, described tuning and modulation device are arranged in the casing of qin tail or scroll head, it is characterized in that: described tuning and modulation device comprise organ stop support, string nail, vibration frequency sensor, organ stop and tuning controller; Described vibration frequency sensor is installed on the Yue Shan, the below of every Zheng string, and the relation of measurement vibrations of strings frequency, pitch and interval is sent its measurement result into the tuning controller.

Described string nail is installed on the organ stop support, is connected with the rotating shaft of micromotor in the organ stop; Described string nail rotational angle is realized by the rotation of tuning controller control micromotor.

Described tuning controller has open circuit and two kinds of mode of operations of closed circuit control.Automatically the power of tuning and modulation system is provided by internal battery or external power supply.

When working in open circuit mode, the player need transfer the basis that Zheng carries out before Zheng is played, and for example D transfers in capable tuning.When practical the utility model Zheng, if the melody of being played needs modulation, the player needed preliminary work is carried out in modulation before playing, and the player assigns instruction by button to organ stop, control the rotation of micromotor by the tuning controller, 21 strings of Zheng are carried out tuning.After the adjustment that the basis is transferred was finished, the angle position of the rotor of the pairing micromotor in string nail position was stored by the tuning controller.If the melody of being played needs Zheng to carry out modulation, the player assigns instruction by button to organ stop, control micromotor by the tuning controller and rotate the string nail, change interval relation between vibrations of strings frequency, tone and the string by the tension force that changes string, thereby Zheng is transferred to the mode that needs.Simultaneously, the modulation controller is determined at mode with Zheng from basic tone, total number of degrees of the required rotation of rotor of the pairing micromotor of each root string when for example D turns to needed other modes, and the result stored.Before Zheng is played or among the process that Zheng is played, when needs when some modes change into other modes, the player presses the button of other modes that representative need be transformed into, by the result of modulation controller according to storage, micromotor is assigned instruction, forward the string nail to other modes desired angle position, to realize the automatically fast modulation of Zheng in the music playing process.

When the utility model works in closed mode, all strings of Zheng are the required vibration frequency that reaches under 12 modes, be stored among the tuning controller with the form of e-file form, described vibration frequency sensor, in order to measuring vibration frequency and the interval relation of all strings under 12 modes of music of Zheng, and compare with the data in being stored in form.If the Zheng player need carry out tuning or modulation to Zheng, the Zheng player is logical to press the button of representing the player to require the mode that reaches, at this moment the tuning controller begins to control the rotation of micromotor, makes vibrations of strings frequency and tone change.The controller of modulation simultaneously receives from the relevant string vibration frequency of vibration transducer and the signal of tone, after vibrations of strings frequency and tone have reached predetermined requirement, the rotation of micromotor stops automatically, and is finished by demonstration tuning of tone display lamp or modulation.In the time of under the Zheng modulation device work closed mode state described in the utility model, the tuning of Zheng and modulation can be finished automatically, and the sense of hearing that no longer needs to rely on the player comes the pitch of string is made judgement.

The utility model is provided with the display lamp of modulation counter control under the string at Zheng Yue Shan place, be used for showing the position of root of pairing each octave of each mode of Zheng, as the prompting to the Zheng player.Root is generally 1 (dou) sound or 5 (so) sound.

The utlity model has following advantage:

The utility model is a kind of based on automatic tuning and modulation device on the modern industry automatic control technology of traditional Zheng design, under the prerequisite of the structure that does not change traditional Zheng, tone color, tonequality, volume and playing method, realize Zheng between 12 music modes automatically, arbitrarily, modulation fast and accurately.When the utility model is operated under the closed mode, can carry out automatic tuning to each mode of Zheng.

Embodiment

The utility model is mounted in the auxiliary device in the tuning casing of Zheng qin afterbody.As shown in Figure 1, an end of the string 1 of Zheng is fixed on the string nail 3 of Zheng.String nail is installed on the organ stop support 6, and is connected with the rotating shaft of micromotor 4 in the organ stop.The change of required string tension force is realized by micromotor 4 rotation string nails 3 when Zheng tuning and modulation.String nail rotational angle is by 5 controls of tuning controller.The measurement of vibrations of strings frequency, pitch and interval relation by be arranged on the Yue Shan 2, vibration frequency sensor 8 under the string 1 realizes that its measurement result is sent into tuning controller 5.Root display lamp 7 is arranged near the below of Zheng Yue Shan 2 every strings.Automatically the power of tuning and modulation system is provided by internal battery or external power supply.
