Description

The one projection screen of band sound equipment
Technical field:
The present invention relates to a kind of projection screen, is a kind of projection screen that is applicable to projections such as family, commercial affairs, office, teaching, amusement, and it is the projection screen that a kind of projection screen and sound system are combined into one.
Background technology:
Existing projection screen is a lot, soft projection screen is arranged, hard projection screen etc., but, these projection screens all voiceless sound ring function, these projection screens can only be watched the image frame on the projection screen when using its projection, and there is not sound, can't hear the corresponding acoustics of sound and image frame, expecting promptly has image that sound effect is arranged again, must increase in addition and buys power amplifier and stereo set is realized, so not only because buy the increase that stereo set causes use cost in addition, and using on-the-spot stereo set and the layout signal transmssion line installed again, promptly taken the space, influenced indoor office of whole portion again, thereby brought inconvenience.General external stereo set quantity is more scattered, volume is big relatively heavier, and power consumption is also big, manipulates and move these equipment more complicated.If the outer equipment that connects of sound realizes that two kinds of inconvenience are arranged: the one, external stereo set volume is all bigger, power consumption is high, be awkward; The 2nd, if adopt be convenient to move, the little external stereo set in power saving, saving space, but do not reach the sound effect of real needs.In addition, all external power amplifiers and stereo set all are producers according to the different consumer groups, stratum and usable range environment, different purposes and the serial stereo set of producing does not exist versatility, shared property.If sound effect is realized by connecting peripheral hardware power amplifier and stereo set when using projector, projection screen, can cause difference so because of sound equipment ornaments position, the image frame of sound field effect and screen can produce asynchrony phenomenon, can cause the dynamic distance direction feeling of image frame and sound effect inharmonious, can allow the people that vision and asynchronous sense are acoustically arranged.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of projection screen and stereo set integrated, can really reach audio-visual synchronous, the accurate sound field effect of image and sound localization, the one projection screen of the band sound equipment that the audio-visual devices volume is little, power consumption is low, easy to operate.
Purpose of the present invention can realize by following technical measures:
