Description
Technical field
The present invention relates to the stereophonic sound system field in audio- visual technique, specifically a kind of cinema seat multichannel sterego speaker system.
Background technology
Currently, global multichannel sterego movie theatre adopts the multichannel sterego speaker system centered on theater.So-called multichannel sterego speaker system typically refers to left and right main sound channel（Based on music signal）Speaker system+center channels（Based on voice signal）Speaker system+left and right circular sound channel（Based on background effect signal）Speaker system+subwoofer sound channel（Ultra-low frequency signal）Speaker system, constitutes a multichannel sterego speaker system distribution mode amplified for movie theatre.This kind of mode is recorded above-mentioned 6 channel audio sound tracks Signal separators by during multichannel sterego film making, corresponding channel separation is carried out respectively during projection by above-mentioned 6 speaker systems again to reset and amplify, the sound equipment for making whole movie theatre shows the synthetic effect of above-mentioned 6 sound channels, this speaker system distribution mode for widely being adopted also is known as 5.1 stereophonic sound system distribution modes, i.e., left main sound channel+right main sound channel+center channels+left side is around sound channel+right surround sound channel（It is commonly called as 5 sound channels）Individually add a subwoofer sound channel again（It is commonly called as .1）Speaker system distribution mode, so being also known as 5.1 modes；Also occur in that in the recent period and add again that on the basis of 5.1 overhead is referred to as the speaker system of " scene sound channel " effect in the speaker system that ceiling amplifies down, is commonly called as 6.1 systems；Besides wall adds two around channel speaker system towards auditorium direction from after movie theatre on the basis of 5.1, composition is commonly called as the speaker system for 7.1, or on the basis of 6.1 again from after movie theatre wall towards auditorium direction along with two around channel speaker systems, composition is commonly called as 9 channel speaker systems.No matter how current multichannel sterego theatre loudspeaker system changes, its basis is 5.1 more universal systems, and current so-called 5.1 multichannel sterego speaker system is centered on auditorium, multi-channel speaker system distribution to be carried out around it around auditorium：The left front of auditorium is left main sound channel speaker system, and the major function of the sound channel is that the L channel based on cinemusic is amplified；The right front of auditorium is right main sound channel speaker system, and the major function of the sound channel is that the R channel based on cinemusic is amplified；Auditorium dead ahead is center channels speaker system, and the major function of the sound channel is that the center channels based on film dialogue i.e. voice are amplified；Auditorium right side side or right lateral side side are right surround channel speaker system, and the major function of the sound channel is that the right surround sound channel based on film background and its effect is amplified；, for left around channel speaker system, the major function of the sound channel is that the left side based on film background and its effect is amplified around sound channel for auditorium left side side or left back side；Before auditorium（Or anywhere）It is placed with subwoofer channel speaker system（It is commonly called as " subwoofer "）, major function is that the intrasonic in cinemusic or effect sound is amplified（Because subwoofer frequency response is in 120Hz or below 80Hz, its sound wave does not have directivity, so the position of subwoofer channel speaker system does not affect the sound field effect of listening process）.
The multi-channel speaker system distribution mode of current movie theatre, be one kind centered on auditorium, left main sound channel, center channels, right main sound channel, the left speaker systems such as sound channel, right surround sound channel, subwoofer sound channel that surround are carried out around auditorium surrounding to be distributed, in the mode of this kind of speaker system distribution, there is following inevasible defect in it：
First, from terms of physicss' angle, the more remote acoustic pressure of sound source is lower, different from the acoustic energy obtained under conditions of different angles from sound source different distance.Due to each the spectators' seat in current movie theatre（Spectators）With its same sound source（All channel speaker systems）Distance and angle it is all different, so each seat（Spectators）The sound-filed simulation for being obtained is also different with acoustic pressure distribution standard, that is to say, that the multichannel sterego speaker system distribution mode of current movie theatre covers each seat due to each sound channel（Spectators）Distance it is different, angle is different, so can not give each seat（Spectators）Uniform acoustic pressure, uniform sound field, cause most seats（Spectators）Real multichannel sterego effect can not be obtained.The sound-filed simulation of current all multichannel movie theatres：Left main sound channel speaker system, right main sound channel speaker system, center channels speaker system, left channel speaker system, right surround channel speaker system etc. of surrounding being respectively around auditorium and dividing mode for cloth, its sound-filed simulation is to all seats centered on auditorium（Spectators）Lack of balance sound-filed simulation is carried out, therefore, except all multi-channel speaker system sound fields cover the seat in region in a balanced way（Spectators）Can hear outside multichannel sterego effect（Strictly only 1 spectators of whole movie theatre can hear）, remaining seat（Spectators）Real multichannel sterego effect can not all be heard, because only obtain in auditorium all multi-channel speaker system sound field alternate coverings definitely in a balanced way under the conditions of can just hear real multichannel sterego effect, the sound-filed simulation of current multichannel movie theatre can meet only only some or several seats of the condition.The application of multichannel sterego movie theatre technology, is to allow all spectators that multichannel sterego effect, but the speaker system distribution mode in the multichannel sterego technology of current all movie theatres can be heard then not with each seat essentially（Spectators）Centered on construction multichannel sterego reproducing process, cause most seats（Spectators）Can't hear real multichannel sterego effect.
Fig. 1 illustrates that the speaker system distribution of current multichannel movie theatre causes the seat kept left in the face of screen axis（Spectators）Hear L channel（Left main sound channel speaker system, a left side are around channel speaker system）Sound be more than R channel（Right main sound channel speaker system, right surround channel speaker system）Sound, conversely, and facing the seat that screen axis is kept right（Spectators）Hear R channel（Right main sound channel speaker system, right surround channel speaker system）Sound be more than L channel（Left main sound channel speaker system, a left side are around channel speaker system）Sound, from axis more away from seat（Spectators）Just less hear the sound of relative direction sound channel, farther seat（Spectators）The sound of relative direction sound channel is even can't hear at all.
That is, current multichannel sterego movie theatre can hear the seat of real multichannel sterego due to being limited by the restriction of existing speaker system distribution mode（Spectators）Seldom, if from the face of screen axis more away from, the multichannel effect heard is poorer, until can't hear multichannel effect.
In other words, the played in stereo technology of existing multichannel movie theatre is involved in the significant deficiency of speaker system distribution mode, define a kind of " pseudoscience " played in stereo technology, because multichannel movie theatre sterophonic technique is for each spectator services, the final purpose of its technology that amplifies is to allow each seat（Spectators）Uniform acoustic pressure and sound field can be obtained, can obtain same multichannel sterego effect, and saying on current multichannel sterego speaker system stricti jurise can only allow a seat（Spectators）Real multichannel sterego sense of hearing can be obtained, because in current multichannel sterego speaker system distribution mode, only one seat（Spectators）The center of the alternate covering sound field that amplifies in all speaker systems of multichannel, in addition, other all seats（Spectators）This center is not at, especially in the face of seat that screen axis is more remote（Spectators）Obtained multichannel heterogeneity sound field covers bigger.
Second, it is limited by distribution mode, and acoustic pressure is unable to uniform fold, makes front-seat spectators excessive with the acoustic pressure difference of pittite.The speaker system distribution mode of current all movie theatres covers uneven to the acoustic pressure of spectators：Front-row seats（Spectators）Resulting acoustic pressure is far longer than back seat（Spectators）, because the distance of sounding point and listening point often increases by 1 times, acoustical power can be reduced to 1/4, i.e., distance often doubles, change=10*log (1/4)=- 10*0.6021=-6dB of sound pressure level, so, front-row seats（Spectators）With back seat（Spectators）What is obtained is different acoustic pressure effects.
3rd, because it is to carry out public address to whole movie theatre, so substantial amounts of public address energy fails, for human ear, to cause a large amount of wastes of acoustical power（Invalid acoustic energy）.Acoustic energy is that, by electric energy conversion, the waste of acoustic energy is equal to the waste of electric flux.
Fig. 2（It is invalid acoustic energy beyond oblique square frame in figure）There are a large amount of acoustic energy not to be directed to human ear for the speaker system distribution for illustrating existing movie theatre, only accounting example smaller portions are applied, and greater proportion of acoustic energy becomes on the contrary the redundancy acoustic energy of destruction acoustic enviroment, in order to reduce those acoustic damages of invalid redundancy sound energy reflection to listening environments, movie theatre has to be processed using corresponding sound-absorbing engineering, not only electroacoustic efficiency is low, and is a kind of burden of acoustic enviroment.
4th, the restriction of its speaker system distribution mode is limited by, produce the different defect of sound picture synchronous regime apart from speaker system difference with spectators.Current all movie theatres are limited by the restriction of speaker system distribution mode, front-row seats（Spectators）With back seat（Spectators）The sound heard has the time difference, seat（Spectators）More rearward the time difference is bigger, it is assumed that movie theatre is provided with 10 row's seats（The spacing for often arranging seat is 0.8 meter）, then last 23 milliseconds more late than first row spectators of spectators of row hears sound, also just says spectators more rearward, and sound picture synchronization difference is bigger, because the light velocity is 870,000 times of the velocity of sound, current all cinema seats（Spectators）From preposition left main sound channel speaker system, center channels speaker system, right main sound channel speaker system more away from, existing sound picture it is nonsynchronous affect it is bigger.
