Description
Technical field
The utility model relates to musical instrument tuning field, relates in particular to a kind of tuning device with musical instrument of string.
Background technology
Music is indispensable in the life, and especially in the scientific and technological epoch of material desire now crossing current, the urbanite of bustling about enjoys the impayable beautiful impression that music is brought after fatigue, makes body and mind abrupt release tired out.But,, be the key of birth one first melodious music for producing the requisite musical instrument of music.When producing musical instrument and when using musical instrument, all need adjust accurately musical instrument, make it reach the most perfect accuracy in pitch requirement.In early days, for the debugging of musical instrument, be to carry out tuning, but such tuning efficient is not only low, and there is subtle difference in the musical instrument of same tuner debugging by the very high tuner of music attainment with string.Simultaneously constantly fly into ordinary citizen house along with musical instrument; Demand to musical instrument is to increase day by day, but the high tuner of attainment but loses and increases, in order to satisfy the demand in market; Attainment is not that very high tuner regulates by the tuning appearance relatively, thereby has alleviated the continuation development of the problems referred to above.But, for requiring very high musical instrument, simply use the tuning appearance to regulate, do not reach requirement.Because the tuning appearance is actually a kind of sound-frequency measuring meter device, the frequency that the tuner regulates musical instrument adopts spanner to carry out manual adjustments, and the precision of tuning is not high, and the tuner that the music attainment is not high still is difficult to musical instrument is calibrated to best state.
Summary of the invention
The purpose of the utility model embodiment is: a kind of tuning device is provided, has tuning precision height, fireballing characteristics.
A kind of tuning device that the utility model embodiment provides comprises generating laser, imageing sensor, central processing unit and governor motion; Said generating laser reflexes to the laser of launching on the said imageing sensor through pad pasting; Said imageing sensor links to each other with said central processing unit electricity respectively with said governor motion.
Optional, said imageing sensor is a ccd image sensor.
Optional, said pad pasting is reflective pad pasting; The said pad pasting of giving out light is affixed on the string of musical instrument.
Optional, said governor motion comprises stepper motor, mechanical hand and speed reduction gearing; Said stepper motor and said speed reduction gearing drive said mechanical hand and rotate.
Optional, said governor motion comprises reducing motor and mechanical hand; Said reducing motor directly drives said mechanical hand and rotates.
Optional, said central processing unit also is connected with LCD display.
Therefore; Use the technical scheme of the utility model embodiment, adopt generating laser emission laser, reflex on the said ccd image sensor through the reflective pad pasting that is affixed on the musical instrument string; Said ccd image sensor then converts the light signal that receives into analog electrical signal; Said analog electrical signal is a digital electric signal through amplification and analog to digital conversion, and said digital electric signal is transferred to said central processing unit, and said central processing unit then sends corresponding instruction according to said digital electric signal and gives said governor motion; Said governor motion is then corresponding makes corresponding action, drives the mechanical hand rotation through stepper motor and speed reduction gearing.The direction that said mechanical hand rotates and angle all by said central processing unit according to the frequency data of the digital electric signal that receives and standard frequency compare with computing after definite, the precision height.Simultaneously, said governor motion also can adopt and add the directly said mechanical hand rotation of drive of speed motor, can reach same effect.In addition, said central processing unit also is connected with LCD display, can show that said central processing unit receives the frequency values of said digital electric signal, thus the very cheer and bright gap of seeing with standard frequency.Above technical scheme has replaced the mode that existing employing tuner ear is listened, and has improved the precision of tuning greatly, employing be full automatic mechanically actuated, also improved the efficient of adjustment simultaneously greatly.
