Description
Technical field
The present invention relates to movie theatre sound effect apparatus fields, more particularly to one kind is for building cinema screening Room surround sound
The ring curtain system of effect.
Background technique
Sound techniques develop to stereo audio from monophonic, so far recent innovation digital circulating audio technology.Term
It is stereo to be commonly called as the stereo method referred in the illusion audio reproduction for the directionality and auditory perspective being wherein created.Illusion
Creation usually by the configuration of two or more speaker systems using two or more independent voice-grade channels come reality
It is existing.Therefore, term is " stereo " is suitable for so-called " quadraphonic " and " surround sound " system and double-channel, 2 loudspeakers
System.Monophonic sounds are still widely used under the background of today, and one of stereo equipment uses high bandwidth.
The system and method for some prior arts use multiple high end digital circuits, to generate the audio track for record
The natural effect in road.To realize this point, multiple main loudspeakers are used in the system and method for the existing prior art, bass is raised
Sound device and sub-woofer speaker.The existing system and method for other realize digital circuit, to generate a big cone of coverage
Audio frequency effect.In order to achieve this goal, it is provided in existing existing system and method multiple vertical in audio tweeter
And at one as the closed area horizontal position of cinema.However the existing prior art cannot provide good environment with
360 degree of angle of coverage.The existing prior art is to provide a kind of limitation of audio experience on the spot in person simultaneously.Except this it
Outside, existing existing method cannot provide three-dimensional surrounding sound effect.
104145485 A of CN discloses a kind of for generating at least 3-dimensional digital stereo-circulation voice output with 360 degree
Angular range without using the output stage of activated amplifier, while covering horizontal and vertical two systems and listening to layout areas,
Consequently facilitating being evenly distributed surrounding sound effective value regardless of hearer listens with 360 degree of surrounding sound effect on the spot in person
Listen the position of experience.The audio signal of output is synchronized with practical source in three dimensions.Present invention may also apply to earphones
Device to generate 3 D stereo surrounding sound effect, and provides soothening effect, so that user can hear such production
Raw surround sound long time.Once video camera is recorded again, the media with the output of 3-dimensional digital stereo-circulation sound
Content, output video council has the sound being beyond recognition, to provide a piracy protection mechanism.
It includes vertical half entrant sound curtain that 204014074 U of CN, which discloses one kind stereo sound effect device of movie theatre that circles in the air, further includes
Three groups of main loudspeakers, two groups of sub-woofers and surround sound loudspeaker, wherein three groups of main loudspeakers are from left to right respectively a left side
Set main loudspeaker, in set main loudspeaker, main loudspeaker is set on the right side, the point centered on vertical half entrant sound curtain central point, vertical semi-transparent
Main loudspeaker is set in placing after sound curtain central point, is to place curve with vertical half entrant sound curtain circular arc degree, a main loudspeaker left side is set in
Set main loudspeaker and main loudspeaker is set on the right side in the left side that lies on its side of the right side two；Perpendicular bisector upper half of the surround sound loudspeaker in vertical half entrant sound curtain
Portion, lower half place 2~6, and center surround sound loudspeaker up and down is arranged, remaining circulating loudspeaker is with center surround sound
It successively arranges centered on loudspeaker；Lower central surround sound loudspeaker rear is provided with left sub-woofer and right infra-low frequency is raised
Sound device and lower central surround sound loudspeaker constitute triangular layout.
Thus above-mentioned two patent documents it is found that currently, to realize 360 degree of 3-dimensional digital stereo-circulation audios or
It needs to make an issue of on circuit, the sound way of output is done by specially treated by amplifying circuit.It just needs to increase loudspeaker
Quantity, arrange multiple loudspeakers, around the cinema projection Room to achieve the purpose that stereo effect.Both methods is not
But the cost of sound effect device is considerably increased, and the structure of Movie House and installation are more complex, be not suitable for promoting and applying.
Therefore, it is necessary to establish a system, there is big overlay area to generate at least 360 degree of surround sounds.Also have
It must
It establishes a system and provides small hiding information to extract audio track.A system is further also needed, with
Reduce electric power
Consumption.
Summary of the invention
