Iimbonakalo：

I-G-212 isebenzisa isithethi esikhulu esinemigca emithathu esisebenza kakuhle, esinamandla aphezulu. Iqulethe iiyunithi zomqhubi ezisebenzisa i-frequency ephantsi ze-2x12-intshi. Kukho iyunithi enye yomqhubi osebenzisa i-frequency ephakathi ye-intshi ezili-10 ene-horn, kunye neeyunithi ezimbini zomqhubi osebenzisa i-throat ephezulu ye-1.4-intshi (75mm). Iiyunithi zomqhubi osebenzisa i-frequency ephezulu zixhotyiswe nge-waveguide device horn. Iiyunithi zomqhubi osebenzisa i-frequency ephantsi zicwangciswe ngendlela ye-dipole symmetric distribution ejikeleze embindini we-ikhabhinethiIzixhobo eziphakathi neziphezulu kwisakhiwo se-coaxial zifakwe embindini weikhabhinethi, enokuqinisekisa ukudibana okuthe tye kweebhendi zefrikhwensi ezikufutshane kuyilo lwenethiwekhi ye-crossover. Olu yilo lunokwenza ugqumo lwe-directivity oluqhubekayo lwe-90° olunefuthe elihle lolawulo, kwaye umda wolawulo ophantsi ufikelela kwi-250Hz.ikhabhinethiyenziwe nge-Russian birch plywood engeniswe kwamanye amazwe kwaye igqunywe nge-polyurea coating enganyamezeliyo ukutshayelwa nokuguguleka. Umphambili wesithethi ukhuselwe yi-grille yesinyithi eqinileyo.

Kutheni Ndibe NaloIzithethi ze-Line ArrayYiba "nguMntu oKhethekileyo" kwiindawo zobungcali?

Xa indawo yabantu abali-10,000 ifuna izandi ezicacileyo nezihambelanayo, kwaye xa iikonsathi zifuna amava okuva amangalisayo, yintoni eyenza izithethi ze-line array zibe zezona zikhethwayo? Impendulo ikwisiseko sazo sobugcisa kunye nokusebenza kwehlabathi lokwenyani! Izithethi zemveli zisasaza amaza esandi ngokungacwangciswanga, nto leyo ebangela inkunkuma yamandla kunye nokonakala komgangatho wesandi. Izithethi ze-line array, ngokulungiselela ngokuchanekileyo iiyunithi zezithethi, zenza amaza esandi avele ngokuchanekileyo njenge-"targetted sniping" - ngamandla aqokelelweyo kunye nenkunkuma encinci. Umahluko woxinzelelo lwesandi phakathi kweendawo ezikufutshane nezikude unokulawulwa ngaphakathi kwe-3dB, oko kuthetha ukuba nokuba ukwi-front row okanye kwiimitha ezili-100 ukusuka apho, unokuva umgangatho wesandi olinganiselayo nopheleleyo..

Okumangalisa ngakumbi kukuguquka kwayo kokusebenza kakuhle: phantsi kwamandla afanayo, ukugubungela intsimi yesandi kwii-line arrays kuyanda ngokuphindwe kathathu, okulingana nokufikelela kwisiphumo esiphindwe kathathu ngesiqingatha sokusetyenziswa kwamandla. Oku akupheleli nje ekubeni kulawulo lwetekhnoloji kodwa kukwanobuhlobo obuphindwe kabini nohlahlo lwabiwo-mali kunye nokhuseleko lokusingqongileyo. Akumangalisi ukuba, ukusuka kwiikonsathi eziphezulu ukuya kwimicimbi yezemidlalo yamazwe ngamazwe, ukusuka kwimiboniso yeqonga ukuya kwiinkomfa ezinkulu, nanini na xa kufuneka "amava esandi anzulu", izithethi ze-line arrays zihlala ziyindlela engasemva kweqonga.

Iyintoni imfihlo yayo? Iphinda ibumbe imida ye-acoustics isebenzisa imithetho yendalo: ngokulawula iindlela zamaza esandi ngokusebenzisa ukuphazamiseka kwe-array, igxila amandla asasazekileyo "kudonga lwesandi", iqinisekisa ukugqunywa ecaleni kunye nokubonakaliswa okufanayo kwe-vertical. Oku akusiyo nje isithethi, kodwa yintsebenziswano epheleleyo phakathi kweenjineli ze-acoustic kunye nemithetho yefiziksi.
