Piece machine is the electronic guitar organ stop circuit of core, and empty-chord sound gathers audio signal by microphone during tuner, with single-chip microcomputer to empty string
The frequency of sound is detected, and is then contrasted with standard frequency, is revolved according to result by controlled motor rotation to adjust the regulation of string
Button rotating is so as to adjust string elasticity, by being repeated several times until string frequency is harmonized.Although the technical scheme makes tuning
Become simple, but tuning process lacks the interaction with beginner, therefore beginner is difficult to association and independently distinguishes sound and tuning.
How to allow tuning change simple, guide beginner's tuning and attraction beginner to be to the interest and attention rate of guitar
Prior art needs the problem solved.
The content of the invention
The purpose of this utility model is to provide a kind of with temperature correction, the organ stop of intelligent voice prompt function, religion
Can beginner how tuning and to attract beginner to the interest and attention rate of guitar.
Therefore, the utility model provides a kind of organ stop, including sound pick-up, tone color recognition unit, frequency control unit,
Output unit, the sound pick-up is used to receive the sound from guitar, and converts sound into electric signal；
The tone color knows unit and is used to receive the electric signal from sound pick-up, and judges that sound is sent out according to incoming electric signal
From string；
The frequency control unit, the signal being passed to according to tone color recognition unit judge the accuracy in pitch of string, and by accuracy in pitch
As a result exported by output unit；The frequency control unit also includes MCU（Microprocessor Control Unit are micro-
Processing and control element (PCE)）And temperature sensor, the MCU gather current temperature by temperature sensor, to tone color recognition unit
Incoming electric signal carries out temperature difference compensation；
The output unit also includes memory and loudspeaker, and the memory have recorded the audio text of the tuning method of guitar
Part；The output unit sends alarm or voice message according to frequency control unit according to the result of accuracy in pitch.
Preferably, the frequency control unit also includes temperature sensor, and the temperature sensor is NMES TEMPs
Device.
Preferably, the tone color recognition unit also includes frequency identification unit.
Preferably, the output unit also includes LED display.
The beneficial effects of the utility model：
1. frequency control unit combination output unit, the information such as accuracy in pitch, frequency, tuning method are intuitively begun to learn with guitar
Person interacts, and the level of recognizing sounds for improving beginner simultaneously, conveniently grasps tuning method.
2. the temperature information that frequency control unit is gathered by temperature sensor, temperature difference compensation is carried out to the frequency of collection,
Improve organ stop frequency accuracy.

Embodiment
Specific embodiment of the present utility model is described further below：
The utility model provides a kind of organ stop, including sound pick-up 1, tone color recognition unit 2, frequency control unit 3, defeated
Going out unit 4, the sound pick-up 1 is used to receive the sound from guitar, and converts sound into electric signal,
The tone color knows unit 2 and is used to receive the electric signal from sound pick-up, and judges sound according to incoming electric signal
From string；
The frequency control unit 3, the signal being passed to according to tone color recognition unit 2 judge the accuracy in pitch of string, and by accuracy in pitch
Result pass through output unit 4 output 4；The frequency control unit 3 also includes MCU32 and temperature sensor 31, the MCU32
Current temperature is gathered by temperature sensor 31, frequency control unit 3 passes according to temperature sensor 31 to tone color recognition unit 2
The electric signal entered compensates calibration；
The output unit 4 also includes memory 41 and loudspeaker 42；The output unit 4 according to frequency control unit according to
The result of accuracy in pitch sends sound or voice message, such as frequency is too high or too low, and loudspeaker can send different audio warnings.
In one embodiment of the present utility model, memory 41 have recorded multiple guitar tuning methods or the audio of prompting
File, beginner can train musicality, the concept of training status sound, are easy to practise according to voice message.For example, the Buddhist nun on new
Imperial string is not easy to harmonize, it will usually which more loose, so suggesting being transferred to little higher, then push-and-pull string, pulls loose string, at this moment
Waiting sound can lowly come, then heighten, and be repeated several times until that sound stable recalls to standard pronunciation again later.
In addition, the method for common guitar tuning has using six tuning pipes, single-tone flute, piano or other musical instruments, using adjacent string
Unisonance method, listen empty-chord sound method, resonance method.The key of guitar tuning is：High pitch string is first harmonized as far as possible, then adjusts bass string, because
High pitch string sensitivity is big compared with bass string, is easier to listen standard.The presence due to crank system and each string tension for electric guitar
It is different, it is proposed that to be adjusted since bass string to high pitch string.
In one embodiment of the present utility model, it is contemplated that influence of the temperature to string, temperature sensor 31 are NMES
Temperature sensor.NMES（Nano-Electromechanical System Nano electro-mechanical systems）Temperature sensor 31 is on the one hand
The measurement accuracy of accuracy in pitch is improved, on the other hand reduces the influence to the volume of whole organ stop again.
In one embodiment of the present utility model, the tone color recognition unit 2 also includes frequency identification unit.Frequency is known
Other unit includes multiple bandpass filters, bandpass filter extracted from note signal frequency band corresponding with each string of musical instrument into
Divide, generate the monochord sound signal of each string.
In one embodiment of the present utility model, the output unit 4 also includes LED display.Display screen passes through frequency
The signal of rate controller transmission, show the string of current temperature, the frequency of accuracy in pitch and corresponding sounding.Such as according to spectrum, it is red
Represent the strings of pitch E the 6th, frequency 82.4069Hz；Purple represents descant E1, frequency 329.6276Hz.
During using organ stop provided by the utility model, switch on power first, string, pickup are played respectively by tuning method
Device receives string sound, is translated into electric signal, receives and handles by tone color recognition unit 2, frequency control unit 3, will
The frequency of string and the frequency signal of standard pronunciation are shown by the form of numeral or waveform, and pass through the not homochromy of LED display
Color or loudspeaker 42 prompt user's current frequency（Compared with standard pronunciation）Higher or relatively low, then user can be by playing output unit
4 audio files prerecorded understand and learnt specific tuning method.
Exemplified as above is only for example, not forming to the scope of protection of the utility model to of the present utility model
Limitation, it is every to be belonged to the same or analogous design of the utility model within the scope of protection of the utility model.According to above-mentioned
The announcement and teaching of specification, the utility model those skilled in the art above-mentioned embodiment can also be carried out change and
Modification.Therefore, the utility model is not limited to embodiment disclosed and described above, and utility model some are repaiied
Change and change should also be as falling into scope of the claims of the present utility model.In addition, although used in this specification
Some specific terms, but these terms are merely for convenience of description, do not form any restrictions to the utility model.
