Description

Accompanied with accordion type electronic organ

The utility model belongs to the electronic musical instrument class, particularly relates to portable electronic qin class.

Along with mellotron is universal day by day, a lot of organ-grinders begin to hold a concurrent post the performance of mellotron in recent years, but the left hand accompaniment skill that can use at accordion originally can't adopt on mellotron.Most mellotron users have synesthesia: though bass, harmony accompaniment effect are abundant automatically, it does not have speed to change freely, and always rule is repeating the content reserved in advance in the program simply, is unfavorable for the performance and the performance of artistic individuality.It is stiff, ossified to accompany, and practical efficiency is very low.The accompaniment method that therefore have to adopt piano, organ type to use always, this has brought new difficulty again for most of players (especially vast sparetime), often susceptible does not always catch up with right hand melody part in the left hand accompaniment, simple bass commonly used, a chord are alternately accompanied, and figure is total to need two hands finish (especially when speed is fast), has weakened electronic organ keyboard utilization factor and expressive force.

The purpose of this utility model is keeping on the conditional electronic qin functional effect basis, has applied a performance dish with accordion left hand accompaniment function, thereby this dish becomes an accordion accompaniment formula mellotron with mellotron other parts integrator.

This qin unique point is: kept on each functional effect basis of conditional electronic qin, increased a complete performance dish with accordion left hand bass accompaniment effect on qin panel upper left side.Because the science of accordion left hand bass (bass, chord) key arrangement, practicality is consistent for many years generally acknowledges.When its arrangement principle being moved on to above the mellotron when constituting the performance dish, just can directly adopt the former spectrum of accordion to play.The electronic organ performance person that the accordion playing basis is arranged can reproduce accordion skill and effect from mellotron as long as adapt to a little.Ben Qin compares with accordion also has each button that musical alphabet mark, big, the bass of volume amplitude are all arranged, and chord respectively has characteristics such as multiple tone color variation.The fingering of left hand bass, chord, connection are used very convenient in the playing procedure.C transfers general all the turning of fingering to change, and more can bring into play its effect in impromptu accompaniment.

The present invention finishes as follows.Fig. 1 is this qin working envelope figure, and dotted portion is a concertina bass performance dish, and this dish is the key point different with the conditional electronic qin.When mellotron was in running order, central microprocessor constantly sent the pulse signal of different cycles to the performance dish.All buttons on the dish (1X2 switch) end constitutes according to bass, chord, and arrangement regulation grouping back links to each other with this signal, and the other end then is connected with the corresponding musical alphabet of central microprocessor input end with musical alphabet and after connecting respectively.So when a key or multikey were pressed, the button two ends were connected, pulse signal is got back to central microprocessor.This system sends instruction to sounding circuit after to signal Processing immediately, by the sounding circuit output digital signal corresponding with musical alphabet, thereby exports scale by D/A numeral, analog-converted, wave filter, amplifier, power amplifier.Each scale of electronic organ keyboard produces with performance dish scale production process, is the array mode of different musical alphabets.

Below in conjunction with accompanying drawing this qin differentiated part is described in further detail.

Fig. 2 is this qin schematic appearance.

Fig. 3 a, Fig. 3 b are this qin accordion accompaniment formula performance dish schematic diagrams.

Fig. 4 is performance outside drawing when coiling independent adult and being used with other mellotron.

With reference to Fig. 2, the performance dish is equipped with plurality of keys in the dotted line of qin upper left side, and is evenly distributed by constant slope from top to bottom.With reference to Fig. 3 a, Fig. 3 b.This figure part button (36 bass) that only draws, the actual packing of playing can be selected for use from 36 ┄, 120 basses according to needs, and its principle of work, process are just the same.Fig. 3 a is a bass key circuit principle, and＜1〉is first row's contraposition bass from top to bottom,＜2〉second row's ground bass.Button one end links to each other following musical alphabet key one end: C1, #C1, D1, #D1, F1, F1 are one group, with be connected from central microprocessor button global semaphore O1, another group links to each other following musical alphabet key one end: #F1, G1, #G1, A1, #A1, B1 are connected then with from central microprocessor button global semaphore O2.Totally ten two contacts (C1 to B1) after the identical musical alphabet key of all button other ends connects, corresponding continuous with C1 to B1 respectively from the central microprocessor input end.Fig. 3 b is the chord circuit theory diagrams,＜3〉the 3rd arranges big chord from top to bottom, the little chord of＜4〉the 4th rows, and＜5〉are the 5th row's dominant seventh chord,＜6〉are the 6th row's diminished seventh chord.The chord key circuit is different from the bass key circuit and is: sound of the every key control of bass buttons produces, and three sounds produce so that the formation chord and the every key of chord key is controlled simultaneously.All chord button one ends link to each other with+V, and the other end then connects corresponding chord and produces switching system, and each chord is by a cmos analog switch of key control (C514) circuit, and this circuit utilizes 3 only switches set, 3 control end parallel connections simultaneously.Constitute needs according to chord, one end of 3 groups of switches in all C514 circuit, divide two groups by following musical alphabet connection: C, #C, A, #A, B are one group, C, #C, d, #d, e, f, #f are another group, link to each other respectively with from central microprocessor input end C to #f point is corresponding, when the connection of chord button just has malleation to add to the C514 control end, make the conductings simultaneously of 3 groups of switches, the chord sound equipment that is made of three sounds produces.At this moment, bass, the multiple figure combination of chord just can be finished by hand of player fully with conversion, and performance speed also is random variation.

Accordion accompaniment formula mellotron is that vast mellotron, the accordion person of drilling grasp left hand accompaniment skill rapidly, fully improves the mellotron utilization factor, expressive force has been created good condition.

With reference to Fig. 4, this performance dish also can be made of one separately, becomes the novel attachment device of a kind of mellotron, and additional performance dish (7) is held up by support (12) and is fixed on＜11〉mellotron.Performance dish circuit theory is fully with Fig. 3 a, Fig. 3 b, do not exist together just O1, O2, four contacts of O3, O4,12 contacts of C1 to B1, interior corresponding the linking to each other of relevant circuit of mellotron that 12 contacts of C to #f are all added by plug seated (8), (9), lead-in wire bundle (10), it has identical effect with the incorporate accordion accompaniment formula of performance dish and qin mellotron, can be used with various mellotrons.
