Cov yam ntxwv：

G-212 siv lub tshuab hais lus loj peb txoj kev ua haujlwm siab, muaj zog siab. Nws muaj 2x12-nti tsawg zaus tsav tsheb units. Muaj ib qho 10-nti nruab nrab zaus tsav tsheb unit nrog lub horn, thiab ob 1.4-nti caj pas (75mm) siab zaus compression tsav tsheb units. Cov high-frequency compression tsav tsheb units yog nruab nrog lub waveguide device horn tshwj xeeb. Cov qis zaus tsav tsheb units yog teem rau hauv ib qho dipole symmetric faib nyob ib ncig ntawm lub hauv paus ntawmlub txeeCov khoom nruab nrab thiab siab zaus hauv cov qauv coaxial tau teeb tsa rau hauv nruab nrab ntawmlub txee, uas tuaj yeem ua kom muaj kev sib tshooj du ntawm cov zaus sib ze hauv kev tsim ntawm lub network crossover. Qhov kev tsim no tuaj yeem tsim 90 ° kev them nqi tsis tu ncua nrog kev tswj hwm zoo heev, thiab qhov kev tswj hwm qis dua txuas mus txog 250Hz. Lublub txeeyog ua los ntawm cov ntoo plywood birch Lavxias teb sab thiab coated nrog polyurea txheej uas tiv taus kev cuam tshuam thiab hnav. Lub pem hauv ntej ntawm lub tso suab yog tiv thaiv los ntawm lub grille hlau ruaj khov.

Vim Li Cas MuajCov Neeg Hais Lus Kab ArrayUa tus "Xaiv Zoo Tshaj Plaws" hauv Kev Teeb tsa Kev Ua Haujlwm?

Thaum ib qho chaw uas muaj 10,000 tus neeg xav tau cov suab nrov meej thiab sib xws, thiab thaum cov kev hais kwv txhiaj xav tau kev hnov ​​​​​​lus zoo kawg nkaus, dab tsi ua rau cov neeg hais lus line array yog qhov kev xaiv zoo tshaj plaws? Cov lus teb nyob rau hauv lawv cov txuj ci tseem ceeb thiab kev ua tau zoo hauv ntiaj teb tiag tiag! Cov neeg hais lus ib txwm muaj cov suab nrov tawg ua tej daim me me, ua rau lub zog pov tseg thiab lub suab tsis zoo. Cov neeg hais lus line array, los ntawm kev npaj cov chaw hais lus kom raug, ua rau cov suab nrov tawm suab zoo li "targeted sniping" - nrog lub zog sib xyaw thiab pov tseg tsawg kawg nkaus. Qhov sib txawv ntawm lub suab ntawm thaj chaw ze thiab deb tuaj yeem tswj tau hauv 3dB, txhais tau tias txawm tias koj nyob hauv kab pem hauv ntej lossis 100 meters deb, koj tuaj yeem hnov ​​​​​​lub suab zoo thiab tag nrho..

Qhov zoo kawg nkaus ntxiv yog nws qhov kev hloov pauv ntawm kev ua haujlwm zoo: nyob rau hauv tib lub zog, lub suab nrov ntawm cov kab arrays nce 3 zaug, sib npaug rau kev ua tiav peb zaug ntawm cov nyhuv nrog ib nrab ntawm kev siv hluav taws xob. Qhov no tsis yog tsuas yog kev tswj hwm thev naus laus zis xwb tab sis kuj tseem zoo rau kev siv nyiaj txiag thiab kev tiv thaiv ib puag ncig. Tsis muaj qhov xav tsis thoob, los ntawm cov suab paj nruag saum toj kawg nkaus mus rau cov xwm txheej kis las thoob ntiaj teb, los ntawm kev ua yeeb yam mus rau cov rooj sib tham loj, thaum twg xav tau "kev paub suab zoo", cov neeg hais lus kab array yeej ib txwm yog tus ace tom qab.

Nws qhov zais cia yog dab tsi? Nws hloov kho cov ciam teb ntawm acoustics siv cov kev cai lij choj ntawm lub cev: los ntawm kev tswj cov kab suab los ntawm kev cuam tshuam ntawm cov array, nws tsom cov zog faib mus rau hauv "phab ntsa suab", xyuas kom meej tias ob qho tib si kev npog sab thiab kev tso tawm ntsug sib npaug. Qhov no tsis yog tsuas yog lub hais lus xwb, tab sis kev koom tes zoo meej ntawm cov kws ua haujlwm acoustic thiab cov kev cai lij choj ntawm physics.
