7) will to examine for the levels song, in master's instructional video, audio frequency typing storage chip
Can with reference to the instructional video of master and play video self-study when self-taught learner or practitioner oneself practise at home, understand the emotion of melody, strengthen the self-learning ability of oneself.
8) multiple-working mode
The multi-functional Zheng music score of Chinese operas is designed with different patterns for the people of different learning phase: exercise mode, mode of learning, performance pattern etc.The emphasis of different mode is different, and such as exercise mode stresses fingering order, and mode of learning stresses accuracy and the integrality of melody, and performance pattern stresses the strong and weak speed of melody, emotive connotation etc., helps learner's constantly progress.
Electronic score treating apparatus comprises Audio Input Modules A, music score of Chinese operas analysis circuit B, music score of Chinese operas contrast circuit C, page turning control circuit D, string shock detection circuit H, tuning indicating circuit F, standard pronunciation produces circuit I, beat produces circuit J, song audio frequency and video memory circuit K, song calls circuit L, function setting and remote control circuit E, video output circuit G and central processing unit; Described central processing unit is for controlling each element circuit work, and the voice signal of Zither playing is successively through Audio Input Modules, music score of Chinese operas analysis circuit, music score of Chinese operas contrast circuit and page turning control circuit; Tuning indicating circuit is transmitted signals to after string shock detection electric circuit inspection to tuning signal; By carrying out discriminance analysis to the qin sound of Zheng, reaching the accuracy differentiating that Zheng practitioner plays, and the string tuning state of Zheng is shown on a display screen.
This device each several part specific works principle is as follows:
1) audio input interface A and music score of Chinese operas analysis circuit B
The voice signal of the Zheng received is converted to electric signal by acoustic pickup, is sent to audio input interface A, and A delivers to music score of Chinese operas analysis circuit B after carrying out Shape correction to electric signal.
The electric signal of B to the Zheng audio frequency after Shape correction carries out spectrum analysis, analysis result is delivered to central processing unit and C.
Music score of Chinese operas analysis circuit principle of work is: Zither playing signal utilizes signal processing means after converting electric signal to, and time-domain signal is transformed into frequency-region signal, then carries out frequency-domain analysis, obtains the spectrum sequence signal of Zither playing signal, completes music score of Chinese operas analytic function.
2) music score of Chinese operas contrast circuit C and page turning control circuit D
The original song stored in the analysis result that B transmits by music score of Chinese operas contrast circuit C and J carries out Data Comparison, result is delivered to central processing unit and page turning control circuit D.
Whether the comparing result that C transmits by D judges, be the end of this page of music score of Chinese operas, if so, then send page turning signal to central processing unit.
The principle of work of music score of Chinese operas contrast circuit is: adopt time-domain analysis and frequency-domain analysis method to be analyzed by original song, obtain the spectrum sequence signal of original song, and the spectrum sequence signal of the Zither playing signal this signal and music score of Chinese operas analysis circuit B analyzed contrasts, produce comparing result.
Page turning control principle is: central processing unit arranges a pointer, be used to indicate the progress of playing note, the progress that it is played along with Zither playing person moves on music score of Chinese operas display, when pointer movement is to the end note of one page music score of Chinese operas, central processing unit exports lower one page music score of Chinese operas, delivers to music score of Chinese operas display screen by video output circuit G.
3) string shock detection circuit H, tuning indicating circuit F and standard pronunciation produce circuit I
Receive during the work of string vibration-sensing clip in the peg in Zheng zither head, string vibration signal is converted to electric signal, pass
Deliver to H.
The electric signal of H string vibrations carries out Shape correction, and delivers to F.
I generates standard pronunciation electric signal, is sent to F.
F contrasts the electric signal of the string vibrations after Shape correction and standard pronunciation electric signal, and comparing result reaches central processing unit.
String shock detection circuit is made up of circuit such as shock sensor, wave filter, operational amplifier, integrators, the signal of string sensor is after filter filtering, export with the acceleration of Fixed Time Interval, amplify through operational amplifier integration again and be transformed to rate signal, this signal by obtaining displacement after integrator integration, thus records vibration frequency.
Standard pronunciation produces circuit and adopts integrated circuit to make oscillatory circuit, and the vibration of this oscillatory circuit is by Digital Circuit Control, and its vibration frequency is international standard voice frequency (vibration frequency as A1 is 440 hertz).
The string vibration frequency that H records by tuning indicating circuit and the international standard voice frequency that I produces contrast, and are presented on a display screen with index dial form by comparing result.
4) beat produces circuit J
J produces the cadence signal of different frequency, reaches central processing unit.It is according to the beat demand in Zither playing process that beat produces circuit, utilizes signal generating circuit to export the unifrequency sound signal having strong and weak Changing Pattern with a group.
5) song audio frequency and video memory circuit K and song call circuit J
K stores master instructional video, audio frequency, calls circuit J call demonstration for song, and as the canonical reference of C.
J receive central processing unit call instruction after in K, transfer corresponding file, be sent to central processing unit.
6) function setting and remote control circuit E
E receives the remote signal of telepilot, requires to send function setting signal to central processing unit according to various application.
7) video output circuit G
The various results of central processing unit process are converted to vision signal by electric signal by video output circuit G, export TV screen display to.
Fig. 2 is device workflow schematic diagram, as shown in the figure:
Central processing unit accepts the signal of each circuit transmission, sends instruction and video frequency output electric signal.Central processing unit complete as note automatically identify, wrong identification, automatic page turning, tuning, the function such as beat process.
Before Zheng fan starts study, by electronic score installation's power source switch opens, central processing unit is initialization first, waits for that user selects corresponding function.
1) if select disc-jockey functionality, by debugging one by one 21 Zheng strings, string vibration signal and string standard pronunciation contrast by central processing unit, show the concrete situation of tuning on the tv screen, and assistance Zheng fan harmonizes string sound.
2) if select training function, call required song, be shown on TV screen, the song that fan plays by central processing unit carries out spectrum analysis, and contrast with the song of standard, the right and wrong situation that real-time display fan plays, is convenient to practitioner and corrects a mistake promptly, reach the object that training improves.In this process, central processing unit, by every page of end note and song end note, judges whether that page turning and song play the states such as complete in time, and makes corresponding display on the tv screen.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
