Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, illustrated embodiment is served only for explaining the present invention,
It is not intended to limit the scope of the present invention.For those of ordinary skill in the art, in the premise not paying creative work
Under, all embodiments obtained according to present invention spirit, broadly fall into protection scope of the present invention.
Self adaptation tuning method in the embodiment of the present invention can apply to stringed musical instrument, such as guitar etc..
Fig. 1 is the flow chart of self adaptation tuning method in the embodiment of the present invention.As it is shown in figure 1, in the present embodiment, self adaptation
Tuning method may include steps of:
Step S101, the actual empty-chord sound frequency of every string on detection stringed musical instrument；
In embodiments of the present invention, step S101 may include that the empty string shocking waveshape gathering string；According to the empty string gathered
Shocking waveshape calculates the actual empty-chord sound frequency of string.
As a example by guitar, guitar has 6 strings, and for each string, the empty string shocking waveshape gathering this string can be by such as
Under type realizes: with pick up for this string, then stirs this string, with ADC (Analog-to-Digital Converter, mould
Number converter) circuit gathers the shocking waveshape of pick up output, the empty string shock wave of shocking waveshape this string i.e. of pick up output
Shape.The empty string shocking waveshape of 6 strings of guitar is gathered respectively by above method.
Wherein, pick up is a kind of device that the vibrations of string are converted into the signal of telecommunication, has electromagnetic pick-up and piezoelectricity to pick up
Sound device.
Wherein, the actual empty-chord sound frequency calculating string according to the empty string shocking waveshape gathered may is that F=1/T, wherein, and F
Representing the actual empty-chord sound frequency of string, T is the cycle of sky string shocking waveshape, and T is equal to adjacent two crests in empty string shocking waveshape
Between time interval.See the sound waveform that Fig. 2, Fig. 2 (a) are the identical pitches that two kinds of musical instruments send, due to putting down of waveform
Slippage degree is different, and to result in tone color different, can ignore the difference of tone color when calculating the frequency of pitch, use sound waves
Between crest adjacent in shape, the time calculates the frequency of sound, as shown in Fig. 2 (b).
Step S102, obtains the standard pronunciation frequency of every string on stringed musical instrument；
Step S103, determines the conversion coefficient of every string according to the actual empty-chord sound frequency of every string and standard pronunciation frequency；
Wherein, the conversion coefficient of string can be equal to the standard pronunciation frequency business divided by the actual empty-chord sound frequency gained of string of string
Value.
Step S104, utilizes the conversion coefficient of corresponding string that the actual output voice frequency of corresponding string is converted to actual output sound
The standard pronunciation frequency that frequency is corresponding.
Wherein, the conversion coefficient at string is equal to the standard pronunciation frequency quotient divided by the actual empty-chord sound frequency gained of string of string
In the case of, the standard pronunciation frequency that the actual output voice frequency of corresponding string is corresponding can be equal to the actual output voice frequency of corresponding string
Product with the conversion coefficient of corresponding string.
Below the principle of embodiment of the present invention self adaptation tuning method is described in further details.
The most illustratively theoretical foundation of embodiment of the present invention self adaptation tuning method.On single string, no matter qin
How the tension force of string and density change, only it is to be understood that the standard pronunciation frequency of this string and actual empty-chord sound frequency, it is possible to logical
Cross and calculate the sound that all sounds of output actual on this string are adjusted to be exported.
As a example by guitar:
See Fig. 3, the empty chord length of any one string of guitar is denoted as L1, now the empty string vibration frequency of this string
(namely empty-chord sound frequency) is f1.
Pinning product of guitar, chord length now is denoted as L2, and vibration frequency is f2.
The density of the tension force chord of string, is the most all constant.
From aforesaid formula (1):
Therefore, f2/f1=L1/L2.
Because the structure of guitar has secured, so L1/L2 is a constant.
So on guitar root string, the ratio of the pitch of pitch when pinning guitar one product and empty string is a fixed value.
And this value is unrelated with the material density of the tension force of string and string.
The standard pronunciation frequency assuming this string is A (5 strings of guitar), then the sound of product is #A.Change any material
String, the tension adjustment of string is to arbitrary value.Empty-chord sound frequency is denoted as F1, and the voice frequency of product is denoted as F2.
Because F2/F1=#A/A=L1/L2, so #A=F2*A/F1, wherein, symbol " * " is multiplication operator, and "/" is
Division arithmetic accords with.
Then, any one sound Fn that this string exports not tuning when, can be by being calculated tuning after
The sound Fout that should export, formula is as follows:
Fout=Fn*A/F1, wherein, symbol " * " is multiplication operator, and "/" is division arithmetic symbol.
Wherein, Fn represents the actual output voice frequency under the non-tuning state of this string, and this value can be obtained by measurement.
Wherein, A represents the standard null string voice frequency that this string should be adjusted to, and this value is known fixed value.(guitar 1
～6 the standard empty-chord sound of string be: E, B, G, D, A, E)
Wherein, F1 is the actual empty-chord sound frequency under the non-tuning state of this string, and this value can also be obtained by measurement.
Wherein, corresponding after being the conversion of actual output voice frequency Fn for Fout standard pronunciation frequency.
Wherein, A/F1 is conversion coefficient.
Based on above-mentioned theoretical foundation, it is illustrated by way of example the conversion to standard pronunciation frequency of the actual empty-chord sound frequency the most again
Process.
Empty-chord sound rate for guitar:
International first standard pitch is A=440HZ；
International second standard pitch is A=439HZ；
International 3rd standard pitch is A=438HZ.
As follows by calculating the theoretical pitch (twelve-tone equal temperament) of each string empty-chord sound of guitar:
1 string sky string, pitch e1, frequency f=440.0000/2^ (5/12)=329.6276Hz；
2 string sky strings, pitch b, frequency f=440.0000/2^ (10/12)=246.9417Hz；
3 string sky strings, pitch g, frequency f=440.0000/2^ (14/12)=195.9977Hz；
4 string sky strings, pitch d, frequency f=440.0000/2^ (19/12)=146.8324Hz；
5 string sky strings, pitch A, frequency f=440.0000/2^ (24/12)=110.0000Hz；
6 string sky strings, pitch E, frequency f=440.0000/2^ (29/12)=82.4069Hz.
Assuming that the sound waveform data such as Fig. 4 (a) sampled is shown, the frequency of waveform shown in Fig. 4 (a) is F0=1/T0.
Want to be adjusted to the frequency of waveform shown in Fig. 4 (a) N times of primary frequency, then can be by between each sampled point of this waveform
Time interval shortens N times, then obtains the waveform as shown in Fig. 4 (b).
The frequency of waveform shown in Fig. 4 (b) is F1=1/T1.
Because T1=T0/N, so F1=N*F0.Wherein, symbol " * " is multiplication operator, and N is conversion coefficient.

Any one string just can be looked for install in the case of answering tuning method.
Three are, decrease the material for string and select and the restriction of neck fixed form.Due to the embodiment of the present invention
Self adaptation tuning method be with algorithm adjust actual audio rate to standard pronunciation frequency, so the tension force of string can be tried one's best little by one
Point, it is only necessary to ensure that the certain feel of player is the most permissible, the tensile requirements much lower that string be can bear by this, thus
The material making string selects and the fixed form of neck has had more possibility.This is conducive to the excellent of stringed musical instrument structure and volume
