Abstract

The utility model relates to a high-precision tone corrector for correcting tunes from a visual sense and tuning various music instruments. The utility model is characterized in that a liquid crystal display is provided with cent indication and musical alphabet indication. An interior circuit has connected relation that a sensor is connected with a signal processor which is composed of two-stage amplifiers IC1, IC2, the output end of the signal processor is connected with the input end of a microcomputer, and the output end of the microcomputer is respectively connected with the liquid crystal display and an LED display and is used for displaying the cent indication, an intonation pointer and an intonation indicating lamp; a keystroke is connected with the input end of the microcomputer, and a power supply is respectively connected with the processor, the sensor and the microcomputer through an electronic switch Q1. Cents can be displayed through the musical alphabet indication or the comparison of the musical alphabet indication and string number indication, and meanwhile, the intonation pointer and the intonation indicating lamp can be adopted. The high and low of the tones can be visually differentiated from the visual sense through three kinds of display functions, various music instruments can be tuned in a manual control or a self control mode, and the tones are corrected rapidly, accurately and stably. The utility model is especially suitable for tuning five kinds of usual music instruments, namely, a koto, a guitar, a violin, a lute and an Erhu in the mode of manual control.

Description

The high precision CALIBRATION

Technical field

The utility model relates to tuning on one kind of multiple musical instruments, relates in particular to a kind of high precision CALIBRATION of coming tuner from vision.

Background technology

At present, electronic tonometer on the market, just show English alphabet and arabic numeral, the musical alphabet of expression tuner and string preface etc., the overwhelming majority in the colony of use CALIBRATION is the musical instrument beginner, for relating to musical alphabet, the string preface, the music theory knowledge of group preface etc. also is not familiar with understanding, and, though the musical alphabet of the simple and clear reaction tuner of displaying contents and string preface etc., its weak point are, the manual tuning of the incompatible five kinds of musical instruments commonly used of CALIBRATION, no cent indicated number, degree of accuracy is not high, shows instability, is difficult to make the beginner more intuitively from visually helping the height of explanation sound.

Summary of the invention

In order to overcome the deficiency that prior art exists, the utility model provides a kind of manual tuner of five kinds of musical instruments commonly used and the automatic control tuner of various musical instruments, offers an explanation the height of sound, the not only fast but also accurate a kind of high precision CALIBRATION of check and correction sound from visual multi-angle.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of high precision CALIBRATION, comprise accuracy in pitch pointer on the LCD, string number indication, accuracy in pitch refers to lamp on the LCD display, and acoustic pickup, button, its characteristics, LCD is equipped with the cent indication, the musical alphabet indication, the its internal circuit annexation: sensor connects signal processor, signal processor is formed its output terminal by two-stage amplifier and is connected with the microcomputer input end, the microcomputer output terminal respectively with LCD, light-emitting diode display connects, and is used to show the cent indication, the accuracy in pitch pointer, accuracy in pitch refers to that the lamp button connects the microcomputer input end, power supply by electronic switch respectively with processor, sensor, microcomputer connects.

The beneficial effects of the utility model are: press the K3 option keys and press K4 and go up that line unit shows cent by string number indication and musical alphabet indication contrast under line unit or the K5, simultaneously, adopt accuracy in pitch pointer and accuracy in pitch to refer to lamp, three kinds of Presentation Functions, offer an explanation the height of sound intuitively from vision, can carry out automatic tuning to various musical instruments, the check and correction sound is not only fast but also accurate and stable, especially more is applicable to the manual tuning of Zheng, guitar, violin, Chinese lute, urheen.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural drawing of the present utility model;

Fig. 2 is a circuit process flow diagram of the present utility model;

Fig. 3 is circuit theory diagrams of the present utility model.

Embodiment

Fig. 1-shown in Figure 3, a kind of high precision CALIBRATION, comprise accuracy in pitch pointer 12 on the LCD 5, string number indication 11, accuracy in pitch refers to lamp 9 on the LCD display, and acoustic pickup 13, button 4, be characterized in, LCD 5 is equipped with cent indication 8, musical alphabet indication 10, its internal circuit annexation: sensor 1 connects signal processor 2, and signal processor 2 is formed its output terminal by two-stage amplifier and is connected with microcomputer 3 input ends, microcomputer 3 output terminals respectively with LCD 5, light-emitting diode display 6 connects, and is used to show cent indication 8, accuracy in pitch pointer 12, accuracy in pitch refer to lamp 9, button 4 connects microcomputers 3 input ends, power supply 7 by electronic switch Q1 respectively with processor 2, sensor 1, microcomputer 3 connects.

The 13 to the 15 pin of described microcomputer 3 respectively with LCD display 6 on accuracy in pitch refer to that lamp 9 diode D3-D1 are connected, the 16 to the 19 pin of described microcomputer 3 connects the K5-K2 on the button 4 respectively, and first pin of microcomputer 3 and the K1 on the 20 pin and the button 4 are connected to form the unlatching that circuit loop is used to control CALIBRATION.

Among Fig. 1, button 4 comprises the K1 on ﹠ off switch, K2 frequency modulation key, K3 option keys, the last line unit of K4, line unit under the K5, LCD 5 shows: cent indication 8, musical alphabet indication 10, string number indication 11, accuracy in pitch pointer 12, three accuracy in pitch refer to lamp 9, built-in sensors in the light-emitting diode display 6.

Manual pattern is suitable for 5 kinds of musical instruments commonly used, in the use, presses the K1 on ﹠ off switch earlier, glimmers after five seconds, refers on selected " musical instrument " by option keys K3 " ↑ ", and LCD 5 shows: cent indication 8, musical alphabet indication 10, string number indication 11, accuracy in pitch pointer 12.

1) press K4 and go up line unit or press the descending key assignments string of K5 number, musical alphabet indication 10 shows cent with the contrast of string number indication 11 in the LCD 5, and cent indication 8 shows " 0 " accuracy in pitch, shows that " Lo " sound is low excessively, and demonstration " Hi " sound is too high.
