Description
(1) technical field
The utility model relates to a kind of piano acoustic control automatic playing system, belongs to musical instrument technical field.
(2) background technology
Under existing technical situation, piano can generally be played by people.Along with the development of technology, slowly there is the automatic playing system replacing people to play, as just provided a kind of automatic piano playing device by micro computer and drived control in patent of invention " automatic piano playing system " (application number: 01128471.4 applying date: 2001-09-18), in Japanese Patent Application Laid-Open No.2005-196074 and Japanese Patent Application Laid-Open No.2005-084578, and for example disclose the typical case of music performance system.But these simple piano automatic playing systems can only be that the machinery of computer and piano is unilaterally played, can not with singer conversate formula cooperation play.
(3) summary of the invention
The utility model is in order to make up the defect of prior art, provide a kind of structure simple, both automatic player piano can be provided to accompany for player, and also tone can be provided to judge for singing voice practitioner, the piano acoustic control automatic playing system of the aid of other piano tuning can also be used as.
The utility model is achieved by the following technical solution:
A kind of piano acoustic control automatic playing system, it is characterized in that: comprise sound collecting disposal system and piano automatic playing system, described sound collecting disposal system is made up of sound collection means, sound detection device and sound processing apparatus; Described piano automatic playing system comprises drive unit and permanent magnet, just sensor is being provided with to the place of permanent magnet, sensing element installed by the circuit board of microcomputer central processor CPU, described permanent magnet is arranged on key lower end, permanent magnet comprises movable magnet and iron core, and iron core is connected with key by key connecting link.
Wherein:
Described sound collection means comprises microphone and voice signal gatherer, and microphone will be collected by airborne sound wave, and sound collected by voice signal gatherer; Sound detection device involving vibrations detecting device and signal propagation controller, wherein vibrating detector be attached to around sound source, the Vibration propagation medium that is different from air in Vibration propagation characteristic, and be vibration signal by described vibration medium reverts, signal propagation controller is connected on pick-up unit, main detection source of students is vibration or noise, thus carries out detecting and screening; Sound processing apparatus is made up of analog/digital conversion circuit and sound processing control apparatus, mainly carries out process to voice signal and transforms, thus be transferred to key.
Described sound detection device and sound processing apparatus are arranged in microcomputer central processor CPU.
The utility model is realized by following principle of work: the utility model is on the basis of traditional piano, drive unit and permanent magnet are installed under piano key, just to the local sensor installation of permanent magnet, on circuit boards sensing element is installed, the voice signal exported by CPU again and cross analog/digital conversion circuit and process, finally on fingerboard, automatic playing is out.
The beneficial effects of the utility model are: structure is simple, easy to use; Both automatic player piano can be provided to accompany for player, and also tone can be provided to judge for singing voice practitioner, the aid of other piano tuning can also be used as.
(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 the utility model key sectional view;
Accompanying drawing 3 is the utility model process flow diagram.
In figure: 1, microcomputer central processor CPU; 2, key; 3, movable magnet; 4, iron core; 5, key connecting link; 6, voice signal gatherer.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model piano acoustic control automatic playing system as depicted in figs. 1 and 2, comprise sound collecting disposal system and piano automatic playing system, described sound collecting disposal system is made up of sound collection means, sound detection device and sound processing apparatus; Described piano automatic playing system comprises drive unit and permanent magnet, just sensor is being provided with to the place of permanent magnet, sensing element installed by the circuit board of microcomputer central processor CPU1, described permanent magnet is arranged on key 2 lower end, permanent magnet comprises movable magnet 3 and iron core 4, and iron core 4 is connected with key 2 by key connecting link 5.
As shown in Figure 3 after singer sounds, voice signal gatherer 6 can collect voice signal, voice signal gatherer 6 is converted to voice signal to its sound wave by by air borne, sound wave imports microcomputer central processor CPU1 into after being converted into voice signal, sound detection device harmony sound processor is had in microcomputer central processor CPU1, voice signal carries out process and transforms in microcomputer central processor CPU1, sound detection device checks vibration signal, voice signal is carried out classification process, the tone of assonance is mated again by microcomputer central processor CPU1, carry out record, finally export electromagnetic signal, export electromagnetic signal by microcomputer central processor CPU1 and occur to movable magnet 3, movable magnet 3 is movable on iron core 4 according to electromagnetic signal, thus drive key connecting link 5, thus drive key 2 to play, player also can set up accompaniment figure by microcomputer central processor CPU1 in advance, thus coordinate the piano automatic playing of monophone when singing, produce more abundant acoustics.
For singing voice practitioner, system can collect pronunciation signal by voice signal gatherer 6, voice signal imports microcomputer central processor CPU1 process into, mate similar tone signal, be converted into electromagnetic signal afterwards, be transferred to movable magnet 3, movable magnet 3 is movable on iron core 4 according to electromagnetic signal, thus drive key connecting link 5, key connecting link 5 is movable thus drive key 2 to play, according to the position of key 2 and sound, such practitioner just can judge that whether the pronunciation of oneself is accurate.
For piano tuning person, this system can as the aid of other piano tuning, by playing corresponding piano key 2, can judge that whether the musical note of piano is accurate, debugged piano, corresponding sound is sent by what play corresponding key 2, system collects pronunciation signal by voice signal gatherer 6, import microcomputer central processor CPU1 process afterwards into, mate similar tone signal immediately, be converted into electromagnetic signal afterwards, be transferred to movable magnet 3, movable magnet 3 will be movable on iron core 4 according to electromagnetic signal, thus drive key connecting link 5, key connecting link 5 is movable thus drive key 2 to play, according to key 2, such piano tuning person just can judge that whether the tone of debugged piano is accurate, thus carry out auxiliary temperament.
