Abstract
The present invention relates to a kind of device by micro processor controls storer composite music.It has brought into play the functional characteristics of microprocessor control able to programme, make the music encoding in the storer can be reduced into music with stylizing according to people's wish, and can realize automatic program locate device, the layout play list, changing music transfers not and musical performance speed, select functions such as single instrument playing music, can help people to learn to give song recitals, under the situation that lacks musical instrument accompaniment and accompaniment personnel, can replace piano, pipe organ, violin etc., because what the music encoding storer adopted is large scale integrated chip, have the big characteristics of memory capacity, a chip can be stored thousands of song songs.
Description
The present invention relates to a kind of device by micro processor controls storer composite music.
Existing mellotron and electronic synthesizer can synthesize the accompaniment melody, and theme then need could realize that by player's performance existing in addition electronic synthesizer only has the function of simple synthetic reproducing music.
The purpose of this invention is to provide a kind of programming Control function that can utilize microprocessor, make music encoding in the storer be reduced into the device of music according to people's wish with stylizing.
For achieving the above object, technical scheme of the present invention is, adopt the peripheral operation display device, IO interface, microprocessor (CPU), music encoding storer (ROM), scale generator (S.G.), D/A, audio signal amplifier, loudspeaker and power circuit etc. constitute the present invention, its each several part annexation is, the peripheral operation display device is connected with IO interface, IO interface is connected with CPU, CPU is connected with scale generator with the music encoding storer, also be connected between music encoding storer and the scale generator, scale generator is connected with audio signal amplifier through behind the D/A, audio signal amplifier links to each other with loudspeaker again, and power circuit then provides electric energy for each parts among the present invention.In the use, CPU accepts the instructions of peripheral operation display device by the IO interface input, under pre-set software systems are supported, control music encoding storer and scale generator with stylizing, according to the desired mode of instruction, order is taken out from the music encoding storer, decodes through scale generator with the music track of input instruction appointment, and then, be reduced into music signal by loudspeaker at last through steering D/A conversion, sound signal amplification.
The invention has the advantages that, adopted microprocessor able to programme (CPU) chip after, make desirable multiple broadcast functions of use to realize by means of pre-set support software.The present invention keys in corresponding instruction by digital code keyboard, both can select the melody that to play, can set the number of times that repeats to play arbitrarily again, can also play multi part melody (He Zou) or only play wherein a certain part (single melody solo), can also arrange the order of a series of melodies broadcasts in addition and the performance content of a certain melody is carried out layout, for example, add the Quan Qu etc. that strikes up again after certain several trifle of playing in " moving into one's husband's household upon marriage ", the first playing music.The present invention can change the tone of melody or the musical instrument that conversion is played by status switch or button input instruction, as: piano, pipe organ, clarinet, trumpet etc.; By potentiometer or button input instruction, can only change the speed of music playing and do not change former tone.In addition, because the music encoding storer among the present invention adopts large scale integrated chip, the music track memory space is big on the one hand, can reach thousands of head, and on the other hand, storer adopts replaceable storage card, and the song memory space can further expand.
Introduce a specific embodiment of the present invention below in conjunction with accompanying drawing.
Accompanying drawing 1, structured flowchart of the present invention.
Accompanying drawing 2, embodiment of the invention structural principle block diagram.
As shown in Figure 2, the peripheral operation display device of present embodiment comprises: digital code keyboard, two status switches, two slip variable potentiometers and a code translator, a LCD (LCD).Digital code keyboard can be realized programming, as selecting, sort play list, determine the pass and the speed of music playing, and the musical instrument of selection solo etc., it is other that status switch is used for the accent of conversion music, another status switch then is used for selecting solo (commonly used) musical instrument, a slip variable potentiometer is used for changing the speed of music playing, another then is used for controlling volume, code translator (4543) and LCD in time show the instruction of digital code keyboard input, and the model of other each chip assembly is respectively:
CPU-V20 ROM-27C512
IO interface-8155 scale generators-Y8314
In addition, the music encoding storer adopts replaceable storage card, and the song memory space is enlarged.
Claims (3)
1, a kind of multi-function music generator, it is by the peripheral operation display device, IO interface, microprocessor, the music encoding storer, scale generator, D/A, audio signal amplifier, formation such as loudspeaker and power circuit, it is characterized in that: the peripheral operation display device is connected with IO interface, IO interface is connected with microprocessor, microprocessor is connected with scale generator with the music encoding storer, also be connected between music encoding storer and the scale generator, scale generator is connected with audio signal amplifier through behind the D/A, audio signal amplifier is connected with loudspeaker, power circuit then provides electric energy for each parts, in use, microprocessor is accepted the peripheral operation instruction by IO interface, display device then shows instructions, under the software systems that pre-set are supported, control music encoding storer and scale generator with stylizing, with the music track of input instruction appointment according to the desired mode of instruction, order is taken out from the music encoding storer, decode through scale generator, and then through steering D/A conversion, become sound signal, send loudspeaker to be reduced into music signal the sound signal of amplifying at last.
2, multi-function music generator according to claim 1, it is characterized in that: the peripheral operation display device comprises digital code keyboard, status switch, variable potentiometer and LCD, above-mentioned each switch, potentiometer, digital code keyboard all are connected with IO interface, and LCD is connected with IO interface through code translator.
3, multi-function music generator according to claim 1 is characterized in that: the music encoding storer adopts convertible storage card.
