Description
Technical field
The present invention relates to electronic musical instrument realize and electronic device technology, particularly relating to can the speaker battle array of flexible configuration
Row realize the device of a kind of universal electric musical instrument with spatial audio effect sense.
Background technology
Electronic musical instrument refers to that player triggers electronic signal by limited means so that it is utilizes electronic synthesis technology or adopts
Sample technology sends the musical instrument of sound by electroacoustic equipment, such as electronic organ, electronic drum etc..
Traditional instrument typically leans on the vibration of string, film, spring, plate or metallic object etc. to send sound.Such as violin class, urheen kind and bullet
Stringed musical instrument, is sent sound by Chord vibration, and gong is then sent sound by metallic object vibration with pulling out kind musical instrument.Have " musical instrument it
King " piano of laudatory title, it is made up of 88 keys (52 white key, 36 black keys) and metallic cord soundboard, player is by pressing key
Key on dish, affects the gavel that enclose carpet inside piano, then taps steel wire string and sends sound.Violin also passes through
Chord vibration and send sound, it has four strings, is divided into: 1 string (E string), 2 strings (A string), 3 strings (D string) and 4 strings (G string).They
Tonequality be substantially limited by material and corresponding structure, depend on the frequency of vibration of material and its reaction to Chord vibration, excellent
Matter string can blaze abroad the fundamental tone of each sound sent and overtone the most delicately.String vibrates, on string
Each particle for produce simple harmonic oscillation, its direction of vibration is vertical with the direction of propagation of ripple, sends shear wave, then is passed by air
Enter human ear
The sounding body of electronic musical instrument is sound-electricity conversion device, and sound-electricity conversion device converts electrical signals to sound, also cries and raises
Sound device or loudspeaker, comparison many be dynamic speaker, its main element is coil, when different electron energies reaches
During coil, it is interactive with the magnetic field of Magnet that coil produces a kind of energy, and this interaction causes paper disc to vibrate, and makes the density degree of air
Producing change and produce sound, the direction of vibration of this medium particle is consistent with the direction of propagation of ripple, is formed " compressional wave ".
The kind of electronic musical instrument is a lot, and using most is electronic organ and the various electronic synthesizers with MIDI function.
Both maximum differences are that electronic organ uses the tone color sampling of solidification, and major part does not provide tone color editting function, and synthesizer
Tone color editing can be provided and control function, tone color being modified, and then creates oneself exclusive tone color.
Electronic musical instrument is different from traditional instrument, is respectively arranged with quality, is mainly reflected in: 1) sounding body of electronic musical instrument is that electroacoustic turns
Change element, music electrical signal is converted into audio signal.And the sounding body of traditional instrument, substantially string, film, spring, plate or gold
Belong to body etc..2) traditional instrument is the tone color of a kind of single instrument, and electronic musical instrument then can pass through electronic filtering, polishes or modulate,
Show single tone color, it is also possible to analog representation is combined tone color.3) traditional instrument is limited by the physical attribute of musical instrument itself, by self
Range, volume, tone color, the impact of congenital attribute " shape " of the aspect such as playing technique.All of traditional instrument cannot present pure
Pure sound wave, such as sine wave, triangular wave, square wave etc., such as violin, it can only present the range scope of wherein treble,
Can not remove to present the range of bass.The state being limited by " shape " in musical composition and playing procedure then broken by electronic musical instrument.4) pass
The single tone color of system musical instrument is the most mellow and the fullest, and electronic musical instrument is when imitating all kinds of pipes, stringed musical instrument, and skill and technique shows slightly dull, sound
Matter is poor.5) traditional instrument is easily affected by natural climate condition, as bamboo flute there will be pitch in the environment of different temperatures
Difference, drum class or stringed musical instrument affected by humidity, also there will be the change of tone color, pitch.And electronic musical instrument be only limited by voltage,
The impact of the factors such as electric current or electronic component quality, comparatively speaking, it is not easy to affected by natural climate condition.
Current electronic musical instrument can solve the problem that small-sized singing and the accompaniment problem in dance hall, can be in advance by an individual making companion
Playing musical composition or background music, without band, or part replaces band, therefore occupies a tiny space in musical instrument,
But the difference being because tonequality still cannot substitute traditional instrument, traces it to its cause, and the sound of traditional instrument is the letter by string
Harmonic motion sends, and is a kind of shear wave, and the compressional wave of electronic musical instrument speaker carrys out Simulating Transverse Wave and has certain limitation, its
Secondary, its sounding body Limited Number, cause vocal cords number limited.The improvement of electronic musical instrument at present focuses on: 1) on software, research makes
Produce tone color, as several sine-wave oscillators are connected together, change respective frequency, amplitude, produce different tone color；Or
Use voltage-controlled method, frequency, amplitude, waveform, duration, envelope etc. are modulated；Or the method using frequency modulation, waveform is remembered
Recall method, pulse number modulator approach etc., it is also possible to any of the above method is used in mixed way.2) on hardware, then capacity is extended,
Including extension notch, increase floppy disk or hard disk, increase maximum pronunciation number, increase storage capability, extension key etc., make merit
Can be diversified, as a synthesizer become the musical instrument that can send out two kinds, four kinds tone colors the most several simultaneously, i.e. one as several
Platform use etc. so that electronic musical instrument is increasingly heavier and configures immobilization.3) for promoting audition audio, around sense and extension sense
Deng, the reproducing channel of left and right two-way independence is carried out stereophonic reproduction, arranges multiple speakers at sound equipment receiving terminal so that listen
Person places oneself in the midst of in the encirclement of these speakers, to reach the effect of surround sound.The improvement of electronic musical instrument is seldom at software at present
Combine with on hardware, particularly at sound source end, from the sounding body (electricity playing machinery sound generating mechanism and electronic musical instrument of traditional instrument
Sound conversion element) play sound principle promote tonequality and spatial audio effect sense, as electronic organ simulate piano performance, bank goes out
The sound electronic signal come is play through speaker, is based on left and right acoustic channels, and speaker simply plays electroacoustic conversion, so playing
Out there is no spatial audio effect sense so that the sound analogy that tonequality cannot send, later stage receiving terminal or the end that amplifies with piano string
Play by stereosonic effect again or amplify, still reaching to less than good auditory effect.
Flourish along with the Internet, Internet music is also developed, and current online music refers to music
Product is various wired by the Internet, mobile radio communication etc. and wireless mode is propagated, and forms digital music production, propagation
And consumption mode, it is then that user uploads oneself music and downloads other people music towards popular popularization and application.If energy
One song of creation, uploads to network further, the most again by relatively popularizing the different performance side of general electronic musical instrument
Formula, including selecting different musical instruments, different famous expert's playing style etc. is played out, it will Internet music is provided
Personalized service, is more liked by people and the promoting, by the development of more conducively internet music of song.
Summary of the invention
Traditional instrument is simulated by string by the compressional wave that its sound-electricity conversion device sends for current electronic musical instrument
The shear wave that simple harmonic oscillation sends has certain limitation, and spatial audio effect sense lacks, and and maximize for extending its function and consolidate
Determining is difficult to spread to household person and uses, it is difficult to providing personalized service for Internet music, the present invention proposes one
Software and hardware combines the electronic musical instrument of improvement, particularly from the mechanical sound generating mechanism of traditional instrument and broadcasting of electronic musical instrument
The principle of sound reproduction sound is started with, sound source sound-filed simulation characteristic based on sounding body, with can the loudspeaker array of flexible configuration realize

Timbre bank module stores the tone color of various musical instruments.Tone color refers to the sense quality of sound, different sounding bodies due to
Material, structure are different, and the tone color sending sound is also the most different, thus can go to differentiate different pronunciations by the difference of tone color
Body.People feels the difference of sound, and except tone and loudness, it is simply that tone color, the height of tone is decided by the frequency that sounding body vibrates
Rate, the size of loudness is decided by the amplitude that sounding body vibrates.Tone color be differently depending on different overtones, each musical instrument sends
Sound, in addition to a fundamental tone (tone), the overtone also having many different frequencies is adjoint, and these overtones determine it not just
Same tone color, enables a person to pick out different musical instruments.From waveform, fundamental tone is exactly first-harmonic, or makes first harmonic (humorous
Sound), overtone refers to frequency and presents these harmonic waves with fundamental frequency integral multiple, can be referred to as second harmonic successively according to multiple
(homophonic), third harmonic (homophonic) etc..
The tone color file of the various musical instrument of timbre bank module actual storage, tone color file is the wave file that musical instrument sends sound
Parameter File, record is the distribution relation between each harmonic wave of each tone color and the amplitude of each harmonic wave.Specifically, it is right
Each tone color analyzes its frequency spectrum, extracts first-harmonic and the frequency of each harmonic wave (homophonic), range parameter, forms Parameter File.It addition, tone color

Closely high speed radio transmission technology can be considered as, such as ultra broadband etc., so make keyboard and master control end, with some points
Cloth can the loudspeaker array of flexible configuration be the structure of wireless split-type, it is simple to put at home and stage is arranged.
A kind of have spatial audio effect sense can flexible configuration loudspeaker array electronic musical instrument can the raising one's voice of flexible configuration
Device array is formed by some loudspeaker array.Speaker can select volume little.The number of speaker flexibility as required is joined
Put；It addition, loudspeaker array is on flexible circuit board so that loudspeaker array can the most on-demand adjustment, open up flexibly
Becoming or be rolled into arbitrary shape, linear, circular such as plane, curved surface, stereo structure etc., pendulum before the lights, or is suspended on stand
On, it is also possible to the device forming Wearable carries with use.The speaker of flexible configuration can need numbering, and at master control end
Communication module registration, i.e. be formed vocal cords table corresponding with the sequence number of speaker, it is simple to the centralized Control of master control end and flexibility
Configuration.
Above-mentioned loudspeaker array can have different arrangements and combined method, can send sound according to speaker support
Frequency or frequency range arrange, as being divided into bass band array, middle vocal cores array and treble band array or finer
The division of vocal cores.The speaker supporting same frequency or frequency range has multiple, is distributed in the position that space is different, when each leisure not
Same initial time plays same such performance data (audio files), when i.e. using different time delays, then can simulate a string
The vibration of certain harmonic wave.According to the rule of tone color harmonic wave (homophonic), select frequency or the frequency range of the corresponding sound of multiple support
Speaker, according to certain time delay corresponding such performance data of regular broadcasting, then can simulate a string or many
The sound that string sends.Use multiple speaker according to certain time delay regular broadcasting such performance data to simulate string space
On vibration, and the spatial distribution position of each speaker is different, and the array of above-mentioned speaker can be rolled into
Arbitrary shape, forms certain vibration cavity or resonator so that plays sound out and has the strongest spatial audio effect sense.
Above-mentioned speaker has fixing narrowband width, and in support bandwidth, the such performance data of frequency is play.
Above-mentioned speaker includes electroacoustic converting unit, communication unit, control unit, D/A conversion unit, power amplification list
Unit.Electroacoustic converting unit, converts electrical signals to sound.The communication unit of each speaker arranges an identification identifier,
Corresponding with the speaker of oneself numbering.The communication information that communication unit is responsible for the communication module of master control end to send over is carried out
Deblocking, understanding header file, if there being the identification identifier of oneself inside header file, then receiving the control information inside this communication information
With such performance data information, otherwise abandon this information.Control unit according to receive control information, including play vocal cords, intensity,
Time delay and duration, send control command.Intensity is to adjust the loudness played；Time delay is to control when to play；Duration is to play
Time span, according to controlling delivering control command.D/A conversion unit then carries out digital-to-analogue conversion to such performance data information, so
Electroacoustic converting unit is given by power amplification unit after being amplified afterwards.Electroacoustic converting unit then combines the control life that control unit provides
Order carries out orderly broadcasting to such performance data information.
Further illustrate loudspeaker array simulation string pronunciation principle:
First, when single speaker works alone, vibrate in atmosphere as independent sound source, a little while compressed air,
It is made to become " dense ", air expansion a little while, become " sparse ", form the ripple of a series of density change, vibrational energy is passed
Seeing off, the direction of vibration of medium particle is consistent with the direction of propagation of ripple forms " compressional wave ".
And traditional instrument sends sound by the simple harmonic oscillation of string, propagate with the form of shear wave.A piece string plays certain
Tone color causes the vibration of string, and the vibration of string can be divided into the most multifrequency vibration.As, its fundamental frequency of certain tone color is f1, successively
Second harmonic f2=2f1, third harmonic f3=2f1..., n-th harmonic wave fN=Nf1, decomposite the amplitude that each harmonic wave is corresponding
AiAnd initial phaseIt it is i.e. the spectral decomposition of tone color.By recording the frequency of each harmonic wave, amplitude, initial phase, it is possible to
The simple harmonic motion that this harmonic wave is corresponding is describedThe parameter that wherein harmonic wave is important is amplitude
And frequency, initial phase can be regarded as 0, thusX can be simplified toi(Ai,fi), this tone color is the most permissible
WithDescribe.
The propagation on string of certain subharmonic, can regard string as has an once per revolution vibration of a lot of particle, and these particles
It is distributed across various location on string.Therefore these matter can be simulated with the speaker supporting same frequency or frequency range
Point, is placed on the diverse locations such as the crest of harmonic wave, trough, controls its difference playing same such performance data (audio files) and initiates
Moment, then can simulate the vibration of certain harmonic wave of string.Here these speakers of the same such performance data of broadcasting, due to
Broadcasting initial time is different and is referred to as the time delay set of speakers of certain subharmonic.
It is previously mentioned that the frequency spectrum of certain tone color of a string performance can resolve into multiple harmonic wave, therefore selects multiple
Support the speaker of corresponding harmonic frequency or frequency range, according to certain time delay corresponding such performance data of regular broadcasting,
Then can simulate a string or sound that many strings send.For certain tone color, first-harmonic is propagated slow, its time delay needed
Number of loudspeakers is few, and along with the frequency of harmonic wave increases, wants preferably to describe this harmonic wave, then corresponding time delay number of loudspeakers
Need to increase.The time delay of each speaker in the number of time delay set of speakers and the time delay set of speakers of first-harmonic is according to performance
Needs pre-set, the time delay of each speaker in the time delay set of speakers of harmonic wave then can according to the multiple proportion of harmonic wave and
The time delay of each speaker in the time delay set of speakers of first-harmonic is derived according to algorithm.
Principle based on loudspeaker array simulation string pronunciation, the method summing up formation spatial audio effect sense:
The spectral decomposition of a piece string tone color obtains N number of such performance data xi(Ai, fi), i=1, L, N, according to its frequency spectrum characteristic,
The time delay number of loudspeakers of different subharmonic, selects corresponding speaker, simultaneously according to the time delay set of speakers of the first-harmonic arranged
In the time delay of each speaker, obtain the time delay of each speaker in the time delay set of speakers of each harmonic wave.Corresponding raises one's voice
Device obtains these such performance datas, selects the such performance data of oneself the most from the inside, plays out further according to corresponding time delay, due to
The time (sequential) playing audio files is different, is i.e. to have different time delays, this like the shear wave sent at string no
Co-located (such as crest, trough etc.) places speaker, thus simulates the tone color of a string.If the most in an identical manner
Processing the such performance data of many tone colors corresponding to string, that just simulates the spatial audio effect of many strings.At corresponding speaker is possible
In different vocal cores arrays, it is distributed in space diverse location；Additionally the array of speaker can be rolled into arbitrary shape, is formed certain
Vibration cavity or resonator so that the spatial audio effect sense playing sound out is higher.
A kind of have spatial audio effect sense can flexible configuration loudspeaker array electronic musical instrument can the raising one's voice of flexible configuration
Device array, can work independent of keyboard and master control end as the external sound equipment of vocal cords more than.As computer or mobile phone need
When playing certain audio file, use a control software that audio file carries out spectrum analysis and become the audio frequency literary composition of many subbands
Part, be then then forwarded to can flexible configuration loudspeaker array support frequency band speaker play out.
A kind of there is spatial audio effect sense can the workflow explanation of electronic musical instrument device of flexible configuration loudspeaker array
As follows:
The most stored various musical instruments of timbre bank module of master control end and the tone color file of editor, communication module is configured
Good vocal cords table corresponding with the sequence number of speaker, is i.e. to know to have which speaker to control.When there being a music score of Chinese operas to be played,
Open keyboard, master control end and can the respective power supply of loudspeaker array of flexible configuration, start following job step:
1) select to play an instrument, open keyboard, the input music score of Chinese operas.The supervisory control desk of master control end selects one or more to drill
Playing music device, player by corresponding key, is i.e. the input corresponding note of the music score of Chinese operas on keyboard.The input of the music score of Chinese operas can also be passed through
The reading spectrum software of supervisory control desk inputs.
2) music score of Chinese operas resolves.The music score of Chinese operas parsing module of master control end understands and resolves the various music score of Chinese operas, supports to use different sounds
The song that rule is composed.According to the note current with the music score of Chinese operas that play an instrument selected, music score of Chinese operas parsing module to bank transfers phase
The tone color answered, then translates into control information the music score of Chinese operas, including vocal cords, intensity and the duration played, and such performance data information
