At present my company is in respect of frequency enlarge sound, mastering top technology of a world, namely technology of joining together of coupling of complete frequency sound, excogitated acoustical lens module perpendicular array, namely the linear array that average person place thinks.
But the linear array of most enterprise is accurate linear array, not be the linear array on real significance. So major person falls in the situation that does not understand, thinking to make linear array is follow the fashion. Linear array puzzles the most easily person, because a lot of people do not know how to distinguish, want to differentiate, basically have two methods:
The first, angle of high and perpendicular control cannot be more than 1 degree, otherwise 85 meters generate interference necessarily later, must explaining at the same time is to use angle of what means pilot, can be accurate linear array only certainly otherwise.
The 2nd, after be in 150 meters, whether clarity listens those who give 10KHZ above is high frequency, often most person won't have an opportunity to be in 150 try beyond rice listen to linear array, accordingly, a lot of brands, can puzzle through listening to the effect nearly others.
Of traditional sound box alt it is to pass bugle to get together sound energy, rely on chimney to get together just like flashlight light is same, radial diverge, range is narrow, and the means that our acoustical lens collects sound energy, the way that collects light energy with laser is same, cannon-shot is more far, acoustical pressing is more strong.
Linear array (acoustical lens module is perpendicular array)
-- the meaning that researchs technology of joining together of coupling of complete frequency sound
The trend of enlarge sound has been the actual SPL in increasing a concert already (sound pressure level) , raise covers audience range again, this brings about the addition of loudhailer amount inevitably. Loudhailer of groovy date canister load enclothes angle to decide to set scallop array with the level of every sound box normally, the jackknife that brings about mutual and quits interference in order to decrease covers area, be in such permutation to fall, in same just can use a sound box to provide the voice with loud definition only up. To achieve farthermost distance and taller SPL (sound pressure level) and adopt " make array flat " design, bring about in cannot the serious interference on pilot direction. Affect audio quality, analytic force, cover range, although press a manual to arrange (always " optimal " eclectic, because the polar coordinates of separate order canister is answered,change) , between sound box radiant sound wave still cannot systematically coupling, because of this traditional system program from going up at all is defective, more troublesome is the confused sound field that produces by continuity sound source, wasted sound energy, the acoustical lens that achieves as alone as clarity to want so is perpendicular the sound pressure level with same array, traditional array needs place of more perpendicular than this sound lens array to use the amount with times more sound box and greater power, although such volume are quite large but it is quite good to not be equal to sound quality.
