Its characterized in that of this automatic performance of piano acoustic control remembers voluntarily that pedigree all: collect processing system, the automatic performance system of piano and piano including sound and remember the pedigree automatically all, sound collect processing system and form by sound collector, sound signal processor and sound converter, the automatic performance system of piano include drive arrangement and permanent magnet, at the opposite sensor installation of permanent magnet, install sensing element on microcomputer central processing unit CPU's circuit board, the permanent magnet setting is at the key lower extreme, the permanent magnet is including activity magnet and magnetic core, the magnetic core passes through the key connecting rod and is connected with the key, the piano automatic remember that the pedigree is all including the microcomputer. Simple structure, convenient to use, through collection and the processing and the conversion of sound, realize the automation of automatic acoustic controlization of playing of piano and piano note register for easy reference, the practicality is high, and the facilitate promotion is used.
Description
(1) technical field
The utility model relates to a kind of piano acoustic control automatic Playing and automatically remembers spectra system, belongs to musical instrument technical field.
(2) background technology
Under existing technical situation, piano automatic Playing and note spectrum are independently, occurred the automatic playing system of piano at present, but this performance system sets up on the music for piano basis that result transforms, and can not carry out allocating and recording music score according to the sound of singer.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of collection by sound and process and conversion, and the piano acoustic control automatic Playing realizing the acoustic control of piano automatic Playing and the robotization of piano note spectrum remembers spectra system automatically.
The utility model is achieved by the following technical solution:
A kind of piano acoustic control automatic Playing remembers spectra system automatically, it is characterized in that: comprise sound collecting disposal system, piano automatic playing system and piano and automatically remember spectra system, described sound collecting disposal system is made up of sound collector, audio signal processor and sound converter; Described piano automatic playing system comprises drive unit and permanent magnet, at the opposite sensor installation of permanent magnet, sensing element installed by the circuit board of microcomputer central processor CPU, permanent magnet is arranged on key lower end, permanent magnet comprises movable magnet and magnetic core, and magnetic core is connected with key by key connecting link; Described piano remembers that spectra system comprises micro computer automatically.
Wherein:
Described sound collector comprises microphone, and sound wave collected by microphone; Sound Processor Unit involving vibrations detecting device, vibrating detector be attached to around sound source and in Vibration propagation characteristic, be different from the Vibration propagation medium of air, and be vibration signal by described vibration medium reverts; Sound converter comprises analog/digital conversion circuit, and voice signal is converted into electromagnetic signal and staff signal by analog/digital conversion circuit.
The utility model is realized by following principle of work: the utility model is on the basis of piano automatic playing system, add the device of sound collecting and process, with automatic manual memory apparatus, three is combined together, by the collection of sound and process and conversion, realize the acoustic control of piano automatic Playing and the robotization of piano note spectrum, permanent magnet and drive unit are installed under piano key, at the opposite sensor installation of permanent magnet, on circuit boards sensing element is installed, passed through analog/digital conversion circuit again to process, be converted into electromagnetic signal, on fingerboard, automatic playing out, sound is converted into staff signal by sound converter, input micro computer carries out the record of staff, and finally can check or export.
The beneficial effects of the utility model are: structure is simple, easy to use; By the collection of sound and process and conversion, realize the acoustic control of piano automatic Playing and the robotization of piano note spectrum; Practicality is high, easy to utilize.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is key sectional view;
Accompanying drawing 3 is workflow diagram.
In figure: 1, sound collector; 2, audio signal processor; 3, sound converter; 4, micro computer; 5, movable magnet; 6, magnetic core; 7, key connecting link; 8, key.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model piano acoustic control automatic Playing as depicted in figs. 1 and 2 remembers spectra system automatically, comprise sound collecting disposal system, piano automatic playing system and piano and automatically remember spectra system, described sound collecting disposal system is made up of sound collector 1, audio signal processor 2 and sound converter 3; Described piano automatic playing system comprises drive unit and permanent magnet, at the opposite sensor installation of permanent magnet, sensing element installed by the circuit board of micro computer 4 central processor CPU, permanent magnet is arranged on key 8 lower end, permanent magnet comprises movable magnet 5 and magnetic core 6, and magnetic core 6 is connected with key 8 by key connecting link 7; Described piano remembers that spectra system comprises micro computer 4 automatically.
As shown in Figure 3, after singer sings sound, sound collector 1 pair of sound is collected, sound wave imports audio signal processor 2 into after being converted into voice signal, sound check processing reforming unit is had in sound converter 3, voice signal is converted into electromagnetic signal and staff, sound detection device checks vibration signal, voice signal is carried out classification process, micro computer 4 mates the tone of assonance again, carry out record, with output electromagnetic signal, sound converter 3 exports electromagnetic signal and occurs to movable magnet 5, movable magnet 5 is movable on magnetic core 6 according to electromagnetic signal, thus drive key connecting link 7, key connecting link 7 drives key 8 to play, sound is converted into staff signal by sound converter 3, input micro computer 4 carries out the record of staff, and finally can check or export.
