Abstract

An electronic tone calibrator of ancient kite with tone corrected through syllable names is provided, which comprises a shell, a SCM, a control key, a signal detection circuit and an amplifying circuit; the signal detection and amplifier circuit is connected with the input end of the SCM. The utility model is characterized in that: the output end of the SCM is connected with a LCD display and a LED, the stroke and LED spot of the LCD display are used for displaying the syllable names of ancient kite. The ancient kite electronic tone calibrator has excellent design, reasonable structure, high performance; by adopting the ancient kite electronic tone calibrator, the difficulty of tone calibration is reduced for ancient kite learner, the problem of unconformity between the syllable names method and tone calibration practice is solved.

Description

Zheng electronic tonometer with the roll call accordatura

Technical field

The utility model belongs to electronic tonometer, especially a kind of Zheng electronic tonometer with the roll call accordatura.

Background technology

Electronic tonometer is the main tool that the music-lover is used for the musical instrument tuner, existing electronic tonometer is except that general twelve-tone equal temperament CALIBRATION, special-purpose CALIBRATION such as guitar, violin, Zheng are still arranged, but no matter above universal or special CALIBRATION, common characteristic all is based on the west twelve-tone equal temperament, shows musical sound with musical alphabet.This method of musical alphabet of utilizing is given no cause for much criticism for the fixing western musical instrument of transferring of custom application, but then has some forced for be adjusted to main national musical instruments with head.Such as above-mentioned existing Zheng CALIBRATION this phenomenon is arranged promptly.

Summary of the invention

Above-mentioned defective for fear of the prior art existence, the utility model provides a kind of Zheng electronic tonometer with the roll call accordatura, this Zheng CALIBRATION more meets the characteristics of Chinese folk music, and the music-lover that can allow music theory knowledge, musical technique still owe can give the Zheng tuner quickly.

The utility model comprises with the Zheng electronic tonometer of roll call accordatura: casing, single-chip microcomputer, control button, signal deteching circuit and amplifying circuit, input and amplifier circuit are connected to the input end of single-chip microcomputer, it is characterized in that: the single-chip microcomputer output terminal is connected to LCD display, and the pen section of LCD display is used to show the roll call of musical sound that Zheng takes place.

The Zheng electronic tonometer design science of this usefulness roll call accordatura, rational in infrastructure, result of use is good, adopts this Zheng electronic tonometer can alleviate the difficulty of Zheng beginner tuner, has solved the difficult problem that musical alphabet method and Zheng tuner custom is not inconsistent.

Description of drawings

Fig. 1 is the contour structures synoptic diagram of the Zheng electronic tonometer of this usefulness roll call accordatura;

Fig. 2 is a theory diagram of using the Zheng electronic tonometer of roll call accordatura shown in Figure 1;

Fig. 3 is an one embodiment circuit diagram.

Embodiment

Below in conjunction with the embodiment accompanying drawing the utility model is described in detail.

As shown in Figure 1, 2, the Zheng electronic tonometer of this usefulness roll call accordatura comprises casing 1, single-chip microcomputer 7, control button 4, input and amplifying circuit 6, LCD display 3 and some light emitting diodes 2, input and amplifier circuit are connected to the input end of single-chip microcomputer, single-chip microcomputer output termination LCD display 3 and light emitting diode 2, the pen section of LCD display and the bright spot of light emitting diode are used to show the roll call of musical sound that Zheng takes place.

Wherein, the circuit board that is loaded with parts such as single-chip microcomputer, input and amplifying circuit, light emitting diode and LCD places in the casing 1, and light emitting diode 2, LCD 3, control button 4 and microphone 5 are positioned at casing 1 panel one side.

The utility model with the design concept of the Zheng electronic tonometer of roll call accordatura is: utilize microphone to pick up note signal, this note signal is imported in the single-chip microcomputer after amplifying circuit amplifies shaping, calculate the frequency of this musical sound by single-chip microcomputer, be converted into roll call and come out by LCD or some diode displaying.

Among Fig. 3 typical circuit figure, control button 4 connects between the input, output terminal of single-chip microcomputer U1, single-chip microcomputer output termination LCD display 3 and light emitting diode 2, the 6th, input and amplifying unit, signal deteching circuit is general microphone input circuit, amplifying circuit adopts general amplifier, amplifying unit output connects an input end of single-chip microcomputer, the note signal that amplifying unit is sent here calculates the frequency of this musical sound by single-chip microcomputer, is converted into that roll call sends liquid crystal display 3 to and light emitting diode 2 shows relevant roll call.

Claims

1, a kind of Zheng electronic tonometer with the roll call accordatura, comprise: casing, single-chip microcomputer, control button, signal deteching circuit and amplifying circuit, input and amplifier circuit are connected to the input end of single-chip microcomputer, it is characterized in that: the single-chip microcomputer output terminal is connected to LCD display, and the pen section of LCD display is used to show the roll call of musical sound that Zheng takes place.

2, according to the described Zheng electronic tonometer with the roll call accordatura of claim 1, it is characterized in that: also comprise being used to show that several light emitting diodes of musical sound roll call take place Zheng, described some light emitting diodes are connected to the corresponding output terminal of single-chip microcomputer respectively.
