Description
Technical field
The present invention relates to a kind of musical instrument fields, are a kind of zither tuning dresses that tuning can efficiently be rapidly completed specifically
It sets.
Background technique
Chinese zither is a kind of traditional instrument of China, and tone color is graceful, and the song of pop-up is interesting to listen to, is liked for numerous compatriots.Yin Gu
Zither using wooden structures, activity bridge, hang the factors such as string tensioning mode, Chinese zither string vulnerable to ambient temperature and humidity, to play the time long
Short equal influence, tone are easy to happen change.Therefore it needs before playing or when dodgoing carries out tuning, traditional tuning method
It is to rotate qin nail by spanners for attuning to be corrected tone, but the tension by manually adjusting string is not easy to control, slightly not
Careful, string is easy to be pulled off, and tuner process is time-consuming and laborious, not enough accurately.
Summary of the invention
To solve the above problems, not needing the present invention provides a kind of conveniently zither tuning device using tune
Sound spanner, and tuning quickly and easily can be automatically performed to the string that need to arbitrarily correct.
The technical solution adopted by the present invention are as follows: a kind of zither tuning device, including zither head, zither body and zither tail, in zither head
Equipped with the qin nail connecting with string, qin nail attachment device, motor and controller are additionally provided in zither head；Qin nail attachment device,
Motor is connected with controller；Qin nail attachment device includes orthogonal X to gear rack straight guide rail slide unit, Y-direction
With Z-direction ball-screw guide rail slide unit, wherein be provided on Y-direction ball-screw guide rail slide unit string vibration frequency adjustment system,
Including motor and retarder；Qin nail connector is provided on the motor；The position of each string is corresponded on zither body panel
String vibration frequency detection device is provided below；The controller includes D/A converting circuit and motor-drive circuit；String
Vibration frequency detection device detect tuner when string vibration frequency, and send it to in controller, with corresponding string
Target frequency is compared, and according to the deviation of the two, establishes the feedback control system of string frequency, controls string vibration frequency tune
The rotation speed of motor and direction in whole system.
The X by stepper motor or is watched to gear rack straight guide rail slide unit, Y-direction and Z-direction ball-screw guide rail slide unit
Take motor driven.
The string vibration frequency detection device is ultrasonic detection device or infra-red ray detection device.
When needing tuning, that root string to tuner need to be only played, ultrasonic wave or infra-red ray detection device detect automatically
The vibration frequency of the string, and sending it in controller, it is in vibration and its vibration frequency that controller receives for which root string,
To control qin nail connector and corresponding qin nail connection in qin nail attachment device, and by with the target frequency in controller into
Row compares, and the feedback control system of string frequency is established according to bias contribution, drives motor in string vibration frequency adjustment system
Rotation, to realize the tensioning of string and loosen.
The above process, which does not depend on, to be manually adjusted, quick and precisely, time saving and energy saving, to all strings of Chinese zither either before playing
It carries out which root string tone detonieren is tuner still find in playing, can apply.
Detailed description of the invention
Technical solution of the present invention is described further with reference to the accompanying drawing:
Fig. 1 is the overlooking structure diagram of zither tuning device of the invention when zither head case lid is opened；
Wherein: 1. zithers are first；2.X is to gear rack straight guide rail slide unit；3.Z is to ball-screw guide rail slide unit；4. controller；5.Y
To ball-screw guide rail slide unit；6. motor；7. retarder；8. qin follows closely connector；9. qin is followed closely；10. string vibration frequency detection dress

Specific embodiment
As shown in Figure 1, a kind of zither tuning device, including zither head 1, zither body 11 and zither tail, it is equipped in zither head 1 and string
The qin nail 9 of 12 connections is additionally provided with qin nail attachment device, motor 6 and controller 4 in zither head 1；Qin follows closely attachment device, motor 6
It is connected with controller 4；The qin nail attachment device includes that orthogonal X is rolled to gear rack straight guide rail slide unit 2, Y-direction
Ballscrew guide rail slide unit 5, Z-direction ball-screw guide rail slide unit 3, wherein being provided with string vibration on Y-direction ball-screw guide rail slide unit 5
Dynamic frequency adjusts system, including motor 6 and retarder 7；Qin nail connector 8 is provided on the motor 6；It is right on zither body panel
Answer the position of each string that string vibration frequency detection device 10 is provided below；The controller 4 includes digital-to-analogue conversion electricity
Road and motor-drive circuit；The vibration frequency of string when string vibration frequency detection device 10 detects tuner, and send it to
In controller 4, it is compared with the target frequency of corresponding string, according to the deviation of the two, establishes the feedback control of string frequency
System processed controls the rotation speed of motor 6 and direction in string vibration frequency adjustment system.
Wherein, X is sliding to gear rack straight guide rail slide unit 2, Y-direction ball-screw guide rail slide unit 5 and Z-direction ball-screw guide rail
Platform 3 is driven by stepper motor or servo motor.By the setting of XYZ three-dimensional slide unit, it can be achieved that spatially reciprocal of motor 6
Movement, in addition pre-set in controller 4 revolution of motor when slide unit is moved at each qin nail position from origin position with
And each qin nail between move when motor revolution, so as to accurately be parked in the position to tuner string in each tuner,
And realize combination that qin nail connector and qin are followed closely with separate.
In addition, string vibration frequency detection device 10 is ultrasonic detection device or infra-red ray detection device.
When needing tuning, firstly, need to only play that root string 12 to tuner, ultrasonic wave or infra-red ray detection device are certainly
The dynamic vibration frequency for detecting the string 12, and sending it in controller 4, controller 4 receives be any root string in vibration and
Its vibration frequency, to control X to gear rack straight guide rail slide unit 2, Y-direction ball-screw guide rail slide unit 5 and Z-direction ball-screw
Guide rail slide unit 3 is moved at corresponding string position, make 9 connection of qin nail connector 8 and corresponding qin nail, and is passed through and be will test
Vibration frequency is compared with the target frequency in controller 4, and the feedback control system of string frequency is established according to bias contribution,
The rotation speed of motor 6 and direction in string vibration frequency adjustment system are controlled, to realize the tuning of the root string.When the root
After the completion of string tuning, above-mentioned tuning process is repeated, tuning is carried out to the string that in addition need to be corrected.When all tuning works of completion
After work, X is returned to gear rack straight guide rail slide unit 2, Y-direction ball-screw guide rail slide unit 5 and Z-direction ball-screw guide rail slide unit 3
To origin, prepare for tuning next time.
Above-described embodiment is only preferred embodiment of the invention, is not intended as limitation of the invention further, all bases
