Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further.
Embodiment mono-
As shown in Figure 1, a kind of electronic musical instrument ensemble system, it comprises a mellotron and an electronic drum.Described mellotron comprises main control board, storer, key, LED display, power amplifier, loudspeaker, man machine operation interface, sound source circuit board and USB interface, wherein, from hardware configuration, LCD display in the Chinese utility model patent that the mellotron of the present embodiment is 201120534543.3 by application number replaces with LED display, and the emission principle of mellotron is same as the prior art, from storer, read music file, then play accompaniment, user presses key, from sound source circuit board, take out piano sound, and pass through power amplifier, loudspeaker sends piano sound, man machine operation interface is used for choosing song, parameters etc., main control board is processed all signals, storer can adopt SD card, man machine operation interface can adopt touch display screen.The difference of electronic drum and mellotron is only to have replaced key with drum, and principle of work is identical, does not repeat them here.
Introduce in detail the difference of the present embodiment and prior art below.
Mellotron is connected and is communicated by USB line with electronic drum, and it is main process equipment that mellotron is set, and it is from machine equipment that electronic drum is set.
The LED display of the present embodiment is used to indicate user and activates its corresponding sound inductive component (being key or drum).Described LED display comprises multiple LED lamp bars, and each LED lamp bar is made up of multiple LED lamp pearls of from top to bottom arranging successively and equidistantly, the main control board electric connection of described LED display and corresponding electronic musical instrument (being mellotron or electronic drum).
When use, mellotron, for reading the MIDI file of its storage, and the note event of reading in advance two fixed tracks of described MIDI document, two tracks of described appointment can be piano track and tympanitic note rail, according to the LED lamp pearl quantity of LED lamp bar and its spacing and default setup time (as 2.2 seconds), in conjunction with the LED display of corresponding its LED display of track control and electronic drum according to bright light speed from top to bottom, so that lighting to the time lighting of the LED lamp pearl under of the LED lamp pearl going up most of LED lamp bar corresponding to the sound inductive component corresponding with described note event equals described setup time, wherein, described setup time is that described track arrives a period of time before described note event.For example, the corresponding track of mellotron is piano track, pre-read out the time point of each the note event on piano track, then this time point is pushed away to 2.2 seconds forward as setup time, in conjunction with LED lamp quantity and the spacing of the corresponding LED lamp of described note event bar, just can calculate the start time of the bright LED lamp pearl going up most, then every bright next LED lamp pearl how often, LED lamp pearl under making mates with the time point of note time while lighting, thereby indicating user is pressed key matchingly; In like manner, the LED display of electronic drum is carried out bright light according to the data of tympanitic note rail, and other tracks (as violin, guitar etc.) are play with accompaniment form, thereby realizes mellotron and the same first song of electronic drum He Zou.
In addition, because MIDI file is not music file, its storage be note, control the instruction such as parameter, therefore, mellotron is not necessarily chosen piano track and is played, and electronic drum is not necessarily chosen tympanitic note rail and played, can also artificial selecting, mellotron is chosen tympanitic note rail and is played, and so, what sound source circuit board was transferred is exactly tympanitic note.
Embodiment bis-
As shown in Figure 2, the difference of the present embodiment and embodiment mono-is electronic drum a kind of embodiment to replace with mellotron, and the main process equipment of the present embodiment is mellotron A, is mellotron B from machine equipment, and its principle of work is identical with embodiment mono-.
Embodiment tri-
As shown in Figure 3, a kind of electronic musical instrument is played guiding device, comprises an electronic drum.Described electronic drum comprises multiple drums 5, sound source circuit board 10, main control board 7, power amplifier 8, loudspeaker 9, storer 6, man machine operation interface 2 and is used to indicate user the LED display that activates (knocking) corresponding drum 5.Drum 5, sound source circuit board 10, storer 6, man machine operation interface 2 and LED display are all electrically connected with main control board 7, and main control board 7 is connected with loudspeaker 9 by power amplifier 8.
Described LED display comprises multiple LED lamp bars 3, and each LED lamp bar 3 correspondence is arranged on the lateral margin of a drum 5.Described LED lamp bar 3 can be 90 °-175 ° with the angle that knocks plane of drum 5, and the present embodiment is preferably 90 °.LED lamp bar 3 is made up of multiple LED lamp pearls 4 of from top to bottom arranging successively and equidistantly.
The man machine operation interface 2 of the present embodiment preferably adopts touch display screen, and storer 6 preferably adopts SD card.
Sound source circuit board 10, main control board 7, power amplifier 8, loudspeaker 9 are installed in a housing 1, a side of housing 1 described in storer 6, and drum 5, man machine operation interface 2 and LED display are installed in the top of housing 1.
Described electronic drum, for reading the MIDI file of its storage, and pre-read the note event of a fixed track of described MIDI document, according to the LED lamp pearl quantity of LED lamp bar and its spacing and default setup time, control its LED display according to bright light speed from top to bottom, so that lighting to the time lighting of the LED lamp pearl 4 under of the LED lamp pearl 4 going up most of LED lamp bar 3 corresponding to the sound inductive component corresponding with described note event (being drum 5) equals described setup time, wherein, described setup time is that described track arrives a period of time before described note event.
In addition, the electronic drum of the present embodiment can also replace with mellotron, can realize as long as drum 5 is replaced with to key.And the electronic drum of the present embodiment, mellotron all can be applicable to embodiment mono-or embodiment bis-.
For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection domain of the claims in the present invention within.
