Description
Technical field
The invention belongs to multimedia technology field, be specifically related to a kind of height integrated, high-quality multimedia video device for tone frequencies integrated approach and system.
Background technology
Along with the progress and the growth in the living standard of society, society requires increasingly highly to audio/video multimedia audio-visual equipment, not only requires acoustics to get well, and visual effect will get well, and is also easy to install.Along with the demand of various large-scale, high-quality integrated multimedia acoustic products is more and more diversified and personalized; These products are carried out Normalized Design, assembling; Thereby reduce aspects such as cost of goods manufactured and short manufacturing cycle very important meaning is arranged; And traditional manufacturing technology and product can not satisfy market to multi-varieties and small-batch, have more characteristic and meet the product demand that client individual requires pattern and function.
In the prior art, sound wave is variation or several kinds of change comprehensive of the pressure in Elastic medium, propagated, stress, particle displacement, particle velocity etc.When sound source towards periphery during the medium radiative acoustic wave, the zone that has sound wave to exist in the medium is called sound field.
Sound field, that part of medium scope that has sound wave to propagate therein is meant the space that Elastic medium occupied that sound wave exists.Medium can be gas, liquid and solid, and the medium that environmental acoustics relates to mainly is an atmosphere.Sound field can be divided into free found field again and mix sound field etc.Free found field is meant that sound source is in even, isotropic medium, and the sound field that the influence on border can be disregarded is called free found field.In free found field, sound wave is by radiation characteristic not interrupted and propagation intrusively to all directions of sound source.Sound field in the enclosure space is meant that the sound field of sound source radiation in the space that interface surrounded different by specific acoustic impedance is claimed the sound field in the enclosure space.For example machine sends noise in workshop or laboratory, and when the area of door, window or other openings area much smaller than whole border, then indoor sound field just can be regarded the sound field in the enclosure space as approx.Sound source during radiative acoustic wave, propagates into the sound wave on each interface in enclosure space, a part is absorbed by the interface, and a part is reflected.In general room, be through after repeatedly reflecting, the intensity of sound wave just is attenuated to can uncared-for degree.
The present invention studies a kind of sound field characteristic according to enclosure space, reaches the multimedia integration multimedia video device for tone frequencies integrated approach and the system of high-quality tonequality and image quality.
In the sound field of enclosure space, comprise direct sound wave and reverberation sound.Continuously and stably during radiative acoustic wave, the acoustic energy of space each point is the result from the sound wave stack of all directions to sound source in enclosure space.Wherein reflection, the sound wave that directly propagates into certain point are called direct sound wave; Once and repeatedly the stack of reflected sound is called reverberation sound.The intensity of direct sound wave is inversely proportional to the square distance that leaves Sound Source Center.If frequency higher (wavelength is compared very little with bulk), it is equal everywhere that the intensity of reverberation sound can be thought approx.The size of reverberation acoustic energy, outside the Pass having, also relevant with the average sound absorption coefficient at space size and all interfaces with radiation power of sound source.
The present invention obtains preferable indoor acoustic pressure steady-state value scope also through independent research, and apply it to product design, integrated in.In enclosure space stably during radiative acoustic wave, when sound wave was propagated in medium on the one hand, constantly decayed by acoustic energy with acoustical power (W) for sound source, when sound wave runs into the interface again some energy be absorbed; Sound source is constantly replenished acoustic energy again on the other hand.Sound source began behind the sounding through very short a period of time, and acoustic energy just reaches dynamic balance state, and the each point acoustic pressure reaches a steady-state value in this time space.
The indoor direct sound and reverberant are counted when the center distance from the sound source to a point r, the sound pressure p times the average of the squares, ρ0 is the density of air; c is the speed of sound in air; Qθ is In the θ direction of the sound source directivity factor of the radiation, that is, the point of the sound intensity and sound power equivalent to the non-directional sound source at a distance of the same sound intensity ratio; R = S Wei / (1 - Wei) called room constant; S is the total surface area of the interior; Wei Zhu indoor surface average absorption coefficient.
Diffuse field distance is meant that through acoustic pressure decays by the distance inverse ratio rule; Reverberation sound can be similar to thinks that each point all equates in the space; Therefore in a certain distance from sound source, its direct sound wave effective acoustic pressure equates just in time that with the reverberation sound effective acoustic pressure this distance is called diffuse field distance rc.
The acoustic absorptivity at enclosure space volume or interface is big more, and diffuse field distance is just big more.When sound source in the directivity factor of all directions radiation not simultaneously, the diffuse field distance on the different directions is also different.If the non-directional sound source radiation that Qθ THREE IN 1, then the direction of the diffusion field at the same distance, called the reverberation radius.
In the zone less than diffuse field distance, direct sound wave in the permissible error scope, can be ignored the zone of reverberation sound (being reflected sound) influence, as approximate free found field greater than reverberation sound.Otherwise in the zone greater than diffuse field distance, reverberation sound is called reverberant field greater than direct sound wave.
Normal-mode: when sound wave is propagated,, will produce resonance between a pair of rigid interface parallel to each other if distance is the integral multiple of half-wavelength.Correspondent frequency is claimed normal frequency (or natural frequency, resonance frequency), and corresponding standing wave circulation way is claimed the normal modes of vibration, or normal-mode.Three dimensions has a series of various types of normal-mode.Calculating formula about normal frequency is seen room acoustics.
Diffuse sound field: when being excited normal-mode in the enclosure space abundant,, thereby make the sound wave that reaches certain point comprise various possible incident directions because different modes has the specific separately direction of propagation.In this case, except the free found field district in diffuse field distance and in 1/4 wave-length coverage of interface fixedly the interference region, the acoustic density of each point is equal in the space in; The sound intensity that arrives certain point from all directions equates; The phase place that arrives between each wave beam of certain point is random.The sound field that possesses such characteristic is called diffuse sound field.
Desirable diffuse sound field also is difficult to obtain.In low-frequency range, the normal-mode that has been excited is less especially, and the sound wave incident direction that arrives certain point is insufficient, and the fluctuating of each point acoustic density is also bigger.In addition, when there is the material that the surperficial specific acoustic impedance of bulk area differs greatly at the interface, also can make the sound field in the space inhomogeneous.This situation is called the sound field indiffusion or spreads bad.In order to obtain sound field diffusion conditions preferably, for the laboratory of reverberation room or special test noise, considered is taked following measure when design: 1. make the laboratory that enough big volume is arranged especially; 2. make the laboratory that good layout is arranged; 3. at the suitable fixed or movable diffuser of indoor increase.
The present invention also researches and develops rational sound field decay and the reverberation time scope of obtaining.Sound source one stops sounding, and everywhere average acoustic energy density just decays by index percent gradually in the enclosure space.Acoustic density decay to the required time in 1,000,000 original/time and is called the reverberation time.The length of reverberation time is directly proportional with spatial volume, and with the space in sound absorption be inversely proportional to.
Dissimilar normal-modes has the different indices rate of disintegration (or reverberation time).Total decay process is not single exponential disintegration rule, with the rate of disintegration of difference in the time space bigger difference is often arranged also.The inhomogeneities of this reverberation time and the scrambling of the rate of disintegration and bad being closely connected of sound field diffusion.
When sound field spreads when bad, indoor each point sound pressure level and the fluctuating of reverberation time are all bigger.At this moment, in actual acoustic is measured, only obtain the mean value of repeatedly measuring, just can obtain experimental result comparatively accurately at more measuring point.
The present invention has fully used room acoustics (room acoustics) achievement in research, and it is the propagation of sound in the research department and the subject of hearing effect, is the important component part of architectural acoustics.Its objective is to indoor tone quality design theoretical foundation and method are provided.Sound is arranged relevant in indoor propagation with shape, size, structure and the sound-absorbing material in room; Hear effect and then reflect people's subjective feeling, there is different evaluation criterions in the room of different purposes.Indoor, the sonic propagation of sound source radiation is to the interface the time, and part acoustic energy is absorbed, and part is reflected.Usually will be through after repeatedly reflecting, acoustic density just is attenuated to can uncared-for degree.When sound source continuously and stably during radiative acoustic wave, the acoustic energy of space each point is the result from the stack of all directions sound wave.Wherein reflection, the sound wave that directly propagates into certain point by sound source are called direct sound wave; Once and repeatedly the stack of reflective sound wave is called reverberation sound.
Room sound field is synthetic by direct sound wave and reverberation sound, and the acoustic density of direct sound wave is by anti-square law decay, and that the acoustic density of reverberation sound can be thought approx is equal everywhere.The size of reverberation acoustic energy is removed outside the Pass radiant power with sound source has, and is also relevant with the average sound absorption coefficient at space size and each interface.The research of indoor sound transmission.Under different condition, the propagation that can come sound in the research department with ray acoustics method, statistical acoustics method and wave acoustics method respectively.
The ray acoustics method is meant when the diffusivity of research freedom sound field, ignores the wave characteristic of sound, adopts sound ray to describe the method for sound transmission approach.When indoor sound transmission to a size during than the much bigger interface of wave length of sound, the propagation law of available ray acoustics method research sound.This and be according to reflection law with sound ray conceptual approach acoustic propagation approach: the angle of reflection of sound ray equals incidence angle, and reflection sound ray and incident sound ray and normal are at grade.
The present invention utilizes the geometrograph of sound ray to analyze the distribution situation of direct sound wave and nearly secondary reflection sound, avoids between direct sound wave and the first reflection sound bigger delay-time difference being arranged, and avoids the focusing of reflected sound to appear near the auditoria.Through layout near the reflecting surface of sound source, replenish the short reflected sound that postpones, increase with distance with the sound intensity of avoiding the sound source front and degradation occurred significantly descending.
The wave acoustics method is meant the method with the indoor standing wave resonance influence of Research on fluctuation theory.When the physical dimension of Interior Interface and wave length of sound were comparable, the wave characteristic of sound just can not be ignored, and becomes outstanding research emphasis.According to the wave acoustics principle;, the distance between the pair of parallel metope 1 on this dimension, can produce standing wave when equaling the integral multiple n of sound wave half wavelength lambda/2; The compression and sparse " pattern " that are sonic propagation have fixing position in the space, resonance appears in room air vibration in other words.When the people along the standing wave direction when an end moves towards the other end, can feel that the sound intensity has variation fluctuated, height differs at most and can reach about 20 decibels.These frequencies that can produce standing wave are called the normal mode vibration frequency or claim normal frequency.Its result makes sound field extremely inhomogeneous, and the some frequency contents that meet above-mentioned situation in the sound source are too strengthened, and also decays slowlyer than other frequency, therefore will cause serious distortion.
The present invention has carried out the design of high-fidelity symmetry tonequality.The quality of the power of sound, the height of tone and tone color is the essential characteristic of sound.Therefore, in the tonequality design, should accomplish to utilize fully direct sound wave according to the concrete instructions for use in room, the nearly secondary reflection sound that reasonably distributes is correctly controlled reverberation sound.
The frequency response curve of sound-absorbing material can not be a straight line on the interface, when selecting and arrange sound-absorbing material, will take into full account this situation, otherwise can cause frequency distortion.Because people's ear can only be told two sound interval greater than 50 milliseconds, therefore the nearly secondary reflection sound in 50 milliseconds has the effect of strengthening direct sound wave, and this is for the diffusivity of improving sound field, and it is all favourable to improve signal to noise ratio.Should avoid the phenomenon (seeing the tonequality defective) of flutter echo and sound focusing simultaneously as far as possible.The richness cordial feeling of tone color is directly relevant with the reverberation time, and the reverberation time is too short, can feel dry and astringent; And the reverberation time is long, influences the definition of sound again.
The quality of sound system overall technology index performance depends on the quality of each unit self performance, if the technical indicator of each unit in the system is all higher, the technical indicator of entire system is then fine so.Its technical indicator mainly contains six: frequency response, signal to noise ratio, dynamic range, the distortion factor, transient response, stereo crosstalk, the stereo degree of balance; The present invention makes every effort to reach the concrete needs of basis These parameters is regulated, and makes it reach personal needs.
Wherein, frequency response is meant frequency range and the magnitude of acoustic waves of the stereo set playback time variation relation with frequency.General this index that detects is reference with the Frequency and Amplitude of 1000Hz, and is the amplitude of unit representation frequency with logarithm with decibel (dB).It is 20～20000Hz that the overall frequency response of sound system requires in theory.Owing to the reasons such as quality of circuit structure, element, often this requirement can not be reached in actual use, but generally 32～18000Hz will be reached at least.
Signal to noise ratio is meant the ratio of the new noise that sound system produces the acoustical reproduction of source of sound software and whole system, and its noise mainly contains thermal noise, AC noise, machinery noise or the like.General when detecting this index and importing with no signal with the rated output power of replay signal the logarithm ratio decibel (dB) of system noise power output represent.The signal to noise ratio of general sound system needs more than 85dB.
The logarithm value of the ratio of system noise power output when dynamic range is meant sound system playback time maximum undistorted power output with static state, unit is a decibel (dB).General performance preferably the dynamic range of sound system more than 100 (dB).
After distortion is meant that sound system is reset to sound source signal, make some part (waveform, frequency or the like) of former sound source signal that variation take place.The distortion of sound system mainly contains following several kinds:
A. harmonic distortion: so-called harmonic distortion is meant that sound after sound system is reset is than the much more extra harmonic components of original signal source.This extra harmonic components signal is the frequency multiplication or the frequency division of signal source frequency, and it is caused by negative feedback network or amplifier nonlinearity characteristic.The harmonic distortion of high fidelity sound system should be less than 1%.
B. intermodulation distortion: intermodulation distortion also is a kind of nonlinear distortion; It is that plural frequency component is mixed by a certain percentage; Intermodulate between each frequency signal, through producing the nonlinear properties that increase newly behind the tone playing equipment, this signal comprises signal between each signal and that reach difference.
C. transient distortion: transient distortion is claimed transient response again, and its generation mainly is when bigger transient signal is added to amplifier suddenly because the reflection of amplifier is slower, thereby makes signal produce distortion.After generally passing through tone playing equipment with the input square-wave signal, the similar follow-up capability of expressing amplifier of the square-wave waveform whether envelope waveform of observation amplifier output signal is imported to transient signal.
Stereo crosstalk is represented the isolation between left and right two sound channels in the stereo component system, and in fact it reflected left and right two degree that sound channel is crosstalked each other.If it is bigger to crosstalk between two sound channels, the third dimension of the sound of resetting so will weaken.
The stereo degree of balance is represented the difference of left and right sound channels gain in the three-dimensional playback system, if degree of unbalance is excessive, the stereosonic acoustic image location of playback will produce skew.The stereo degree of balance of general high-quality sound system should be less than 1dB.
The range scope of the playback sound of sound system generally can be divided into subwoofer, bass, middle bass, middle pitch, alt, alto, high pitch, eight ranges of extra-high-speed sound.Audio frequency range generally can be divided into four frequency ranges, and promptly low-frequency range (30～150Hz); Medium and low frequency section (150～500Hz); Medium-high frequency section (500～5000Hz); High band (5000～20000Hz).Wherein, 30～150Hz frequency range: can show the low-frequency component of music, make the appreciator experience strong and powerful innervation.150～500Hz frequency range: can show the expressive force of single percussion instrument in music, be the part of expressing dynamics in the low frequency.500～5000Hz frequency range: mainly express the definition of singer's language and the expressive force of string music.5000～20000Hz frequency range: mainly express the lightness of music, but too much can make sound send out broken.
Direct sound field, reflection sound field, direct sound field
When loud speaker is sounded in a room; The audience can hear directly and pass the sound of coming from loud speaker; Here it is direct sound field (indirectfield), but can hear that also this just is called reflection sound field (reverberantfield) from wall, ceiling and sound that the floor reflected back.The audience hears the sound of more direct sound fields; The sound of reflection sound field just more hour, this sound is just good more, because directly the sound of sound field can be controlled; But the sound of reflection sound field is out of contior; Only can add noisy dying, lowering at the bottom of the definition of sound originally, so sit to such an extent that leave the closer audience of audio amplifier and will feel better acoustics directly educating the sound that the field sends; And the audience who is sitting in the back is likely that the reflection sound field sound that they hear is bigger than direct sound field sound, acoustics just can be poor and definition reduce.When sometimes one group of band performs on platform; Because they do not have monitor speaker, and the main sound box of both sides is the position that is placed near entablature, and band and the sound that the singer heard are not let slip from direct sound field fully; The position that they stand just is called not directly sound field; Sound effect is surely not good, and the performance level that this also can have influence on band makes spectators hear not so good performance sound.
Good product, good Environment Design, the installation and debugging that also need get well.Suitable position, suitable dimensions, placement suitable device, it is also more important than buying the product of getting well to a certain extent to debug out suitable effect according to environment and user's hobby, main application etc.The present invention is directed to this demand, researched and developed and to have regulated product size (length and width absolute value and relative scale) within the specific limits according to concrete project installation and debugging needs, make it easy to carry out rational installation and debugging, obtain preferable audio frequency and video effect.And in the existing acoustic product, the function of regulating product size is not provided all generally.
