Description
Technical field
The present invention relates to musical instrument teaching field, particularly relate to a kind of wiping stringed musical instrument teaching side based on radio sensing network
Method.
Background technology
Urheen in the most representational violin having in Western music of existing wiping stringed musical instrument and national music, both of which is only qin
And do not have pitch interval prompting musical instrument.Different with the guitar of plucked string instrument, the qin wiping stringed musical instrument does not has separator bar upper,
Player cannot with the naked eye identify whether the position that oneself finger pressed makes string send correct pitch.For begining to learn
For person, it is understood that whether the melody oneself played falls within is only had two kinds of situations on correct pitch: first player oneself
Person can listen the phenomenon showing whether the melody oneself played has detonieren to have absolute sound sensation；As for the player not having absolute sound sensation
Just can only be dependent on teacher or other people with absolute sound sensation listen to content the instructing of performance for him.Usual music class
Course the most only can on classroom with teacher's interaction one to two hour, other time player can only oneself be in exercise, body
While the people being not equipped with absolute sound sensation can correct because of height for him in good time.Therefore, for the people not having absolute sound sensation, study is wiped
The stage of begining to learn of stringed musical instrument can be quite painful process.
Existing stringed musical instrument tuning instrument can be divided into active with passive type two types: passive type instrument is generally to be found pleasure in
The variator of hand getting, is converted into visual cue information by cresset by pitch, and musician adjusts string further in accordance with information
Elasticity, and then reach the purpose of pitch calibration, the error of such method maximum comes from musician's individuality to pitch cognition
Difference and the variator calibration of each producer differ.The active existing commodity of tuning instrument only have for guitar design fits motor
Deng the automatic tuning mechanism driving assembly to constitute, the active variator being whether embedded on musical instrument or separate with musical instrument body
Active variator, had the most there is not similar designs or product in other kind stringed musical instruments.
Summary of the invention
It is an object of the invention to provide a kind of wiping stringed musical instrument assistant teaching method based on radio sensing network.
For achieving the above object, the technical scheme is that a kind of wiping stringed musical instrument based on radio sensing network
Assistant teaching method, gathers audio signal by wireless sensing device, by calculus of differences circuit and standard audio identification,
Final output LED lamplight optical signal.
As a kind of optimal way of the present invention, specific works step includes:
Step one, shows audio signal sample device, audio storage and output device, calculus of differences circuit, LED signal
Device connects, and builds described wireless sensing device；In audio storage and output device, storage has the correct audio frequency of melody；
Step 2, before musician plays, selects melody correct that will play in described audio storage and output device
Audio frequency；
Step 3, musician strikes up, and audio signal, audio signal sample device are played in audio signal sample device collection
Audio signal is converted into the signal of telecommunication, and output is to calculus of differences circuit；Meanwhile, standard audio storage and output device are by correct sound
Frequently synchronism output is to calculus of differences circuit；Now play audio frequency and correct audio frequency Complete Synchronization；
Step 4, calculus of differences circuit carries out calculus of differences, the electricity of output operation result to performance audio frequency and correct audio frequency
Signal；
Step 5, the signal of telecommunication of operation result exports to LED signal display device, and LED signal display device is by the signal of telecommunication
Being converted into LED color, brightness, Real-time Feedback is to musician；
Step 6, will play audio signal storage and record to audio storage and output device, play as inspecting musician
The foundation of accuracy in pitch.
The invention has the beneficial effects as follows:
The present invention introduces technology of wireless sensing network and combines difference channel and LED semiconductor subassembly by sensing network node
Designing can be as the system of wiping stringed musical instrument assistant teaching aid, after the melody except player being played compares with standard music data
Be converted to the output of visible light signal, also the performance result of player be embedded in the terminal sunk to a little simultaneously, progressively build
The learning portfolio of vertical player, looks back altogether in the future and finds out the weakness that should strengthen training.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below.
A kind of wiping stringed musical instrument assistant teaching method based on radio sensing network, gathers audio frequency by wireless sensing device and believes
Number, by calculus of differences circuit and standard audio identification, finally export the LED lamplight optical signal of comparative result, specifically
Work process is as follows:
Step one, shows audio signal sample device, audio storage and output device, calculus of differences circuit, LED signal
Device connects, and builds described wireless sensing device；In audio storage and output device, storage has the correct audio frequency of melody；
Step 2, before musician plays, selects melody correct that will play in described audio storage and output device
Audio frequency；
Step 3, musician strikes up, and audio signal, audio signal sample device are played in audio signal sample device collection
Audio signal is converted into the signal of telecommunication, and output is to calculus of differences circuit；Meanwhile, standard audio storage and output device are by correct sound
Frequently synchronism output is to calculus of differences circuit；Now play audio frequency and correct audio frequency Complete Synchronization；
Step 4, calculus of differences circuit carries out calculus of differences, the electricity of output operation result to performance audio frequency and correct audio frequency
Signal；
Step 5, the signal of telecommunication of operation result exports to LED signal display device, and LED signal display device is by the signal of telecommunication
Being converted into LED color, brightness, Real-time Feedback is to musician；
Step 6, will play audio signal storage and record to audio storage and output device, play as inspecting musician
The foundation of accuracy in pitch.The data recorded then as inspect afterwards player play accuracy in pitch according to it can also be used to follow the trail of player
The part showed at those phrases needs to strengthen training again.
The present invention uses radio sensing network carry out data collection and transmit standard audio, the network of radio sensing network
Topology construction can use multiple different communications protocol to reach, including using bluetooth, infrared ray, Wifi, WiFAX, radio
Ripple etc..
In the present embodiment, calculus of differences main circuit to be made up of operational amplifier, and operational amplifier receives musician simultaneously
Play audio signal and standard audio signal, be output as on the occasion of, then the red cresset of LED display, for negative value then, LED shows
Blue cresset, if being output as zero, represents that the melody audio frequency that player plays is consistent with standard audio sequence, then LED shows green
Colored lights number.
Additionally, audio signal sample device also can realize signals collecting by the way of the vibration frequency of perception string.LED
Outside lamp is divided by colour recognition, it is also possible to identify signal by brightness output.
Described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into the scope of protection of the invention.
