Abstract
A portable koto trainer comprises the case and the string. The front beam at the right end is the koto head, and the rear beam at the right end is the koto tail. The medium section is the koto body. The portable koto trainer also comprises the electronic acoustic device, the speaker, the power supply (batter box and power socket), the tone regulator and the volume regulator. The string crosses over the front beam, and the rear beam fixedly joins the case. The string connects with the input terminal of the electronic acoustic device. The electronic acoustic device receives the input sound signal from the string and drives the speaker. At the same time, the electronic acoustic device could regulate the tone of the input sound signal with the tome regulator and regulate the speaker with the volume regulator. The koto trainer made with the technical scheme could sound same as or similar to the real koto. However, the volume of the koto trainer is greatly less than that of the real koto, easy to carry and available to regulate the volume.
Description
Technical field
The utility model relates to a kind of musical instrument exercising machine, particularly a kind of Zheng exercising machine that comprises electronic sound-producing device.
Background technology
Zheng is the famous national musical instruments of China, and the prototype great majority of Zheng are about 35 centimetres of 163 cm x, and 21 strings, wild goose post are arranged, can be in order to play as musical instrument.
This ancient musical instrument has attracted increasing fan with its exclusive glamour, and the professional person is wherein arranged, and the amateur is also arranged, and comprises child, social class's white collar, and manual labour gang, retired old man etc., very extensive.We know that any musical instrument of study all is through after the grasp method, and the exercise by diligent effort just can reach the destination of study.Play in the process of Zheng in exercise, the exercise of finger dirigibility is very important, a very crucial exercise.As the saying goes: " song is not from mouth, and fist is not from hand ", reach the own target of being learned, will do constant practice.
Present Zheng is inconvenient to carry because body is big, be in if just put, when working, go on business or situation that other are gone out under, exercise is carried in inconvenience.Sometimes go home very late, think that exercise can influence neighbourhood, household again.These situations all can influence exercise, if do not practice, then finger is day by day stiff, influences improving in study of Zheng.
By the above as seen, the body of Zheng is big, the disadvantages affect of being inconvenient to carry Zheng learner's routine, thereby also restricting the popularization of this traditional instrument.
Summary of the invention
The utility model i.e. volume at above present Zheng is big, and the shortcoming of being inconvenient to carry is utilized electronic sound-producing device, realizes that volume reduces portable Zheng exercising machine.
For achieving the above object, the utility model provides a kind of portable Zheng exercising machine, and this Zheng exercising machine comprises that shell, string, right-hand member front-axle beam are zither head, and the left end back rest is the zither tail, and center section is the zither body, electrophonic musical device, loudspeaker, power supply; String is fixedly received on the shell across front-axle beam, the back rest; String is connected with the electric sounder input end, and electric sounder receives the input audio signal of string and drives the loudspeaker pronunciation.Also can add tone controller, volume adjuster is as the input of electronic sound-producing device.String wherein is connected to the input end of electrophonic musical device, and when the practitioner played, the pronunciation signal that the electrophonic musical device transmits according to string drove the high bass effect that loudspeaker sends notes such as 1,2,3,4,5,6 of similar Zheng.String process and the method that signal passes to electron generating of sounding can be carried out with reference to the principle of the electronic guitar acoustic pickup in the prior art, or with other sensor acquisition vibrations of strings signals.Used power supply can be the battery that is contained in the battery case, also can be the external power supply that supply hub connects, and through power switch control conducting or disconnection.The size of volume adjuster control loudspeaker output volume.Loudspeaker wherein also can be other external pronunciation equipment, drives audio amplifier as the lug machine or by external power amplifier.
According to the utility model, owing to adopted the electrophonic musical device, the size of the exercising machine prototype of Zheng relatively reduces a lot, for example can make the size of 18 centimetres of 25 cm x, be applicable to make and grow 1 meter once, 21 Zheng exercising machines that string is following make exercising machine be easy to carry, and also can carry easily in the occasion of going out and practise.Simultaneously, pronunciation is accurate, good hand touch.Can regulate owing to volume, can adapt to the requirement of different time, varying environment, when also wanting to practise Zither playing, volume can be turned down, thereby can not have influence on the rest in household, neighbourhood when having gone home late.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is a circuit part block scheme of the present utility model.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
According to Fig. 1, the Zheng exercising machine comprises shell 1, string 2, and right-hand member front-axle beam 3 is zither head, and the left end back rest 4 is the zither tail, and center section is a zither body 5; String 2 is fixedly received on the shell across front-axle beam 3, the back rest 4, and circuit part is placed on the enclosure interior of Zheng.The button of associated adjustment, control, knob are installed in the side or the front of Zheng exercising machine.
In this example, the physical dimension of Zheng exercising machine is 25 centimetres (about distance) * 18 centimetres (longitudinal separation), and thickness is 6 centimetres.Size than the prototype of Zheng greatly reduces.According to different needs, different model Zheng exercising machine size can be different.
Circuit part is placed on the enclosure interior of Zheng, and it forms block diagram as shown in Figure 2.Comprise electric sounder 6, battery case, supply hub, power switch 11, loudspeaker 7, tone controller 8, volume adjuster 9.Battery case wherein, supply hub are referred to as power supply 10.
When the practitioner played string, the transmission of sound signals that string sends was to electronic sound-producing device, and electronic sound-producing device drives loudspeaker and sends the corresponding sound identical or close with the Zheng effect.String process and the method that signal passes to electron generating of sounding can adopt the principle of the electronic guitar acoustic pickup in the prior art to carry out.The voice signal that electronic sound-producing device is regulated input according to tone carries out the adjustment of tone, regulates according to volume the sound size of output driving loudspeaker is adjusted.Loudspeaker in the block scheme also can be other external pronunciation equipment, drives audio amplifier as the lug machine or by external power amplifier.Used power supply can be the battery that is contained in the battery case, also can be the external power supply that supply hub connects, and through power switch control conducting or disconnection.
In this embodiment, because described portable Zheng exercising machine has adopted electronic sound-producing device to drive the loudspeaker sounding, obtain the sound effect identical or close, and physical dimension is that about 35 centimetres of 163 cm x significantly are reduced to about 18 centimetres of 25 cm x from the prototype great majority of Zheng with Zheng.Relative Zheng prototype, portability has improved greatly.Simultaneously,, also make things convenient under different occasions and adjust volume, for example volume can be turned down than later the time at night, in order to avoid influence neighbourhood, household because volume can regulate.
