Abstract
A multifunctional electro-acoustic konghou relates to improvement of a plucked national electro-acoustic instrument and is characterized in that an output end of a sensor SR is connected with an input end of a signal conditioner ST, an output end of the signal conditioner ST is connected with an input end of a CPU (central processing unit), and an output end of the CPU is connected with a display D, an audio unit and an MIDI (musical instrument digital interface) respectively. The multifunctional electro-acoustic konghou has the advantages that the multifunctional electro-acoustic konghou is convenient to use and rich in functions, expression is enhanced and dissemination distance is increased, and the konghou has high practical value and broad application field with regard to solo, ensemble and teaching.
Description
Technical field
the utility model belongs to the musical instrument technical field, relates to the improvement of the national electrophonic musical instrument of a kind of type of playing.
Background technology
an ancient plucked stringed instrument is the very ancient plucked string instrument of China, in ancient times except that the imperial palace ceremonial music uses, in also widespread among the people.On the shelf from later stage trecento, so that slowly disappear, see something of the pattern of an ancient plucked stringed instrument on mural painting that can only be former and the embossment.In order to make this musical instrument that disappears for many years reappear stage; Eighties of last century the fifties rises; China musician and musical instrument are made teachers and have been carried out number of research projects, and the figure according to the record of ancient book and the ancient wall preserved designs an ancient plucked stringed instrument of having manufactured experimently several types; But, come so do not promote and spread because these an ancient plucked stringed instruments exist many deficiencies.Up to the eighties of last century early eighties, a kind of novel an ancient plucked stringed instrument---wild goose post an ancient plucked stringed instrument is developed out.Fairly perfect, the science of its structure, sound equipment has national characteristic, thereby is used for music practice by popularization.But traditional an ancient plucked stringed instrument is because volume is limited, when and occasion that do not have public address equipment big in the space played volume a little less than, be difficult to the effect that reaches satisfied.
Summary of the invention
The purpose of
the utility model is: a kind of multi-functional electroacoustic an ancient plucked stringed instrument is provided, and it is to go out the ancient musical instrument of an ancient plucked stringed instrument with the electro-acoustic production.
The technical scheme of
the utility model is: be made up of sensor, signal conditioner, primary processor, audio unit, display, several parts of midi interface, through system software whole electric an ancient plucked stringed instrument carried out sequencing control.
output terminal of sensor SR is connected with the input end of signal conditioner ST, and the output terminal of signal conditioner ST is connected with primary processor CPU input end, and primary processor CPU output terminal is connected with display D, audio unit, midi interface respectively.
The beneficial effect of
the utility model is: a. electricity an ancient plucked stringed instrument is realized the expansion of electro-acoustic function under the prerequisite that does not change traditional an ancient plucked stringed instrument original function, characteristic and style.Under non-electroacoustic mode of operation, can it be played as traditional an ancient plucked stringed instrument.B. after getting into the electroacoustic mode of operation, electric an ancient plucked stringed instrument can directly have the playback of big loudness through loudspeaker when playing.C. connect computing machine through midi interface, can carry out MIDI recording, music score record, make things convenient for the user to remember spectrum, creation.D. the extended function that control program is realized in the electric an ancient plucked stringed instrument comprises: 1. CALIBRATION function, and the string accuracy in pitch regulated in the musical alphabet of the string that is struck that the user can show according to display; 2. pitching instrument function, the standard pronunciation that sends fixed frequency is used for the musical instrument accordatura; 3. the effect device function realizes that abundant tone color changes.E. assemble silencer on the qin body, can connect earphone through receiver J-Horner CK1, convenient individual also can avoid bothering other people when practising.F. can import the sound signal of playing equipment such as into the outside amplifies, recording, sound console in real time through circuit output plughole CK2.
Easy to use, the feature richness of
multi-functional electroacoustic an ancient plucked stringed instrument; The expressive force and the propagation distance of traditional an ancient plucked stringed instrument have been strengthened; No matter be that solo, ensemble or association play, instrumental ensemble so that teaching all has the application of higher utility and broad.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram;
Fig. 2 is the utility model circuit diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
are as shown in the figure, and SR is that ORZ110 type sensor, ST are that RL-17 type signal conditioner, CPU are that YX-Z2640 primary processor, D are that E0443F escope, MIDI are that 501 type midi interfaces, KA are that TM0050B type audio unit, YD are that S501T type audio amplifier, CK1 and CK2 are C635 type audio coupler.
every string is furnished with standalone sensor SR, and its major function is to carry out the collection of music information, is about to vibrations of strings and is transformed into and frequency and the corresponding electric signal of amplitude; The signal entering signal conditioner ST that collects, to signal amplify, filtering, technical finesse such as abate the noise; Treated signal imports primary processor CPU into, changes to the received signal, makes it become digital signal; And analyze; Then be sent to respectively: 1. audio process KA, deliver to loudspeaker YD playback through power amplification, realize having the audio output function of certain power; 2.MIDI interface is realized midi signal output; 3. display D is used for the required icon of the various functions of Display Realization.
Claims (1)
1. multi-functional electroacoustic an ancient plucked stringed instrument; It is characterized in that: the output terminal of sensor SR is connected with the input end of signal conditioner ST; The output terminal of signal conditioner ST is connected with primary processor CPU input end, and primary processor CPU output terminal is connected with display D, audio unit, midi interface respectively.
