Embodiment
The note indicator that the application is described to be used for keyboard instrument mainly is made of note display screen (3), controller (1), universal display device (2) three parts, below in conjunction with accompanying drawing this three part is described in detail, and after a preferred embodiment is provided.
[note display screen]
Because to relate to content more for the note display screen, the ranks that below are divided into the defining of the corresponding viewing area of key, LED are arranged, the selecting for use of LED, four parts of photic zone are described in detail:
1. the corresponding viewing area of key defines
Corresponding the defining of viewing area of key can have two kinds of diverse ways---12 point-scores and 7 point-scores:
So-called 12 point-scores are meant black key and Bai Jian status equalization, according to the width of black key and the width of close black key one end of white key an octave are divided into 12 zones.
So-called 7 point-scores are meant black key and do not wait from the key status, away from the width of black key one end an octave is divided into 7 zones according to white key, and the zone of black key correspondence are the junction of two white key ranges.Adopt this method, the peak width of white key correspondence is distributed to the LED columns of Bai Jian and can so just can be distinguished white-black key more easily by the note width more than black key greater than black key.Therefore, 7 point-scores are method for optimizing.
2.LED ranks arrange
Note display screen (3) luminous displaing part divides the LED that is arranged by ranks to form, and the line direction (4) that LED arranges is parallel with the orientation of keys of keyboard, column direction vertical with the orientation of keys of keyboard (5), and line space equates.
The line number of LED has determined the time range that note display screen (3) can show: line number scope of many time more is long more.Line space has determined the note display screen to show the continuity of piano roller shutter: line space is big more, and continuity is poor more, and the user is easy more to feel not smooth.The line number of LED is The more the better, line space the smaller the better (line space reduces, and same height just needs more LED), but all be to be cost to promote cost.
The arrangement mode of LED row has two kinds---inhomogeneous arrangement and evenly distributed:
So-called inhomogeneous arrangement is meant in the middle of each key corresponding display, and row or a multiple row LED is set.Can be on this theoretical method so that LED and key corresponding relation are better, but effect is not fairly obvious in the actual test.
The so-called evenly distributed column pitch that is meant equates, and column pitch is less than any one key corresponding display width.Because column pitch equates that line space itself equates that also therefore the industrial lattice module that can select for use dot spacing to equate greatly reduces cost.Simultaneously, because dot spacing equates that the note display screen can show some supplementarys in the clear area that does not have note, for example simple literal and shape etc. are in order to information such as indication pedal, fingering, modes.Therefore, evenly distributed is method for optimizing.
3.LED select for use
The selected LED of note display screen can be monochromatic, double-colored even all-colour LED:
It is cheap adopting the monochromatic LED advantage, but shortcoming also is significant: a lot of song right-hand man region separation are also not obvious, adopt monochromatic LED not know and differentiate each self-corresponding note of right-hand man.
Adopt dual-colored LED, right-hand man's note distributes two different colors, can easily differentiate the right-hand man.And dual-colored LED can be by two kinds of different brightness of color multiple color of arranging in pairs or groups out, and then with different color tables information such as key, fingering, chord is shown.
Adopt the all-colour LED effect best, but the all-colour LED cost is too high.
Therefore, adopting dual-colored LED is preferred version.
4. photic zone
Photic zone (7) can be selected light-passing board for use, the frosted paster, even material such as common printer paper, key is to allow the LED light transmission of direct projection (can select the different materials of light transmission power according to required brightness, with not dazzling be fundamental purpose), stop that diffusing of LED background sees through (preventing that background from causing interference to key viewing area sign).
The mark (8) of dividing the key viewing area can directly place photic zone (7) to go up (modes such as printing, stickup), and it is preceding also can to place on the hyaline membrane (modes such as printing, stickup) to cover photic zone (7).The mark (8) of dividing the key viewing area can suitably add boost line or auxiliary pattern, as long as can clear performance go out the key corresponding display.
Photic zone (7) can be that musical alphabet, the roll call of this note also can be numbered musical notation mark or staff mark at the corresponding note information in different keys viewing area (9).
The pattern difference of photic zone (7) in the different keys of same octave viewing area both can be embodied in the difference of color, also can be embodied in the difference of pattern, even both was all inequality.
Photic zone (7) also can be very close in different octaves but the pattern of the identical key of musical alphabet viewing area can be identical, as long as obvious difference is less than the difference of different keys viewing area pattern in the same octave.
[controller]
Controller (1) can be formed for computing machine (comprising desktop computer, notebook computer, panel computer, smart mobile phone etc.) installs the LED display isochronous controller additional, also can customize embedded system (single-chip microcomputer, FPGA, CPLD etc.) as required.
Controller (1) should include midi interface, realizes carrying out data communication with electric keyboard instrument.When controller (1) is computing machine, can select for use the sound card of band midi interface or USB to change converters such as MIDI line; When controller (1) is embedded system, can realize the corresponding interface by serial ports.
[universal display device]
The LCD that universal display device (2) can carry for portable computer also can be all color monitors such as common LCD, CRT monitor, TV, projector.Operate and consider volume and weight for the convenience of the users, should preferably support the LCD of touch operation.
[preferred embodiment]
