Abstract
The utility model relates to a device which controls a memorizer to synthesize music through a microprocessor. The outer operation display unit of the utility model is connected with an input and output interface which is connected with the microprocessor, and the microprocessor is connected with a music encoding memorizer and a musical scale generator. The music encoding memorizer is also connected with the musical scale generator, the musical scale generator is connected with an audio frequency signal amplifier after passing through a number/mode converter, and the audio frequency signal amplifier is connected with a loudspeaker. A power supply circuit provides each component with electric energy. The utility model can automatically select songs, select playing music, change tones and playing speed, etc., and the capacity for storing songs is large.
Description
The utility model relates to a kind of device by micro processor controls storer composite music.
Existing mellotron and electronic synthesizer, though can synthesize accompaniment melody and beat, it can only simply reproduce formula ground and synthesize predetermined accompaniment melody and beat.
The purpose of this utility model provides a kind of programming Control function that can utilize microprocessor, makes the music encoding that leaves in the storer be reduced into the device of music according to people's wish with stylizing.
For achieving the above object, the technical solution of the utility model 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 (accompanying drawing 1), 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.
Advantage of the present utility model is, adopted microprocessor able to programme (CPU) chip after, make desirable multiple broadcast functions of use to realize by means of pre-set software systems.Its volume is little, and function is many, and purposes is wide, and is easy to operate, dependable performance.
Accompanying drawing 1 is the utility model structured flowchart.
Accompanying drawing 2 is the utility model most preferred embodiment theory diagrams.
Accompanying drawing 3 is circuit diagrams of digital code keyboard among the embodiment, code translator, LCD.
Accompanying drawing 4 is circuit diagrams of microprocessing systems among the embodiment.
Accompanying drawing 5 is circuit diagrams of music coded stack among the embodiment.
Below in conjunction with accompanying drawing, introduce a most preferred embodiment of the present utility model.
The composition of this embodiment circuit, one-piece construction and annexation are referring to accompanying drawing 2.
In accompanying drawing 3, (1) is that LCD, (2) are that code translator, (3) are that attachment plug, (4) are digital code keyboards; U1(8088MIN in accompanying drawing 4), U2, U3, U4 have constituted microprocessing systems; Four ROM (read-only memory) (27512) have been formed the music encoding storer in accompanying drawing 5; In accompanying drawing 6, (5) are that IO interface, (6) are gang socket, and the attachment plug (3) in it and the accompanying drawing 3 plugs.(7) be that scale generator, (8) are that D/A, (9) are that audio signal amplifier and loudspeaker, (10) are that power circuit, (11) are that two status switches (accent that is used for the conversion music is other, another be used for selecting several solo musical instruments commonly used), (12) are that speed, (13) that variohm can be used to change music playing are that another variohm can be used to control volume.
Present embodiment electrical schematic diagram accompanying drawing 3 is to being to be mutually related between the accompanying drawing 6, and the connection termination symbol of each an accompanying drawing left side (right side) side has been indicated corresponding annexation between each accompanying drawing.From complete machine, its signals transmission is, from the instruction of digital code keyboard (4) input, a path is through attachment plug (3), and code translator (2) shows on LCD (1) then; Another path is to gang socket (6) through attachment plug (3), arrive microprocessing systems (accompanying drawing 4) through IO interface (5) again, microprocessing systems is being controlled music encoding storer (accompanying drawing 5) and music generator (7), promptly take out and deliver to by command request and be transformed into digital music signal in the scale generator being stored in music encoding in the music encoding storer, D/A (8) changes this digital music signal into analog music signals, deliver to note amplifier (9) at last and amplify, (SP1) sends music sound by loudspeaker.Variohm R25(12) can change the speed of music playing, variohm R14(13) can change volume.SW1 in the status switch (11) transfers other selector switch as music again both as power switch, SW2 be used for selecting several solo musical instruments commonly used (as, pipe organ, piano etc.).In addition, the operate as normal of present embodiment, the corresponding software programs that need join.
Present embodiment in actual use, key 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 one of them part (single melody solo), can also arrange order that a series of melodies play 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.By status switch or button input instruction, can change the tone of melody or the musical instrument that conversion is played in addition, 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 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.
