Acoustics ezisinga obulungi ku home theatre – okulonda n’okukuŋŋaanya enkola n’emikono gyo

Ekigendererwa ekikulu ekya sinema z’awaka kwe kutondawo “presence effect” nga olaba firimu n’okuwuliriza ennyimba. Mu ngeri endala, mu kuddamu okufulumya ebifaananyi n’amaloboozi ag’omutindo ogwa waggulu, okumpi ne sinema. Enkola y’emizindaalo mu sinema y’awaka y’evunaanyizibwa ku ddoboozi eryetoolodde. Mu kwekenneenya kuno, tujja kukyetegereza.

Acoustics for home theatre: kiki kye kiri, kiki kye kirimu ne kiki kye kikozesebwa

Kale, wansi wa acoustics kya mpisa okutegeera akakwate akasembayo mu lujegere lw’ebyuma ebivunaanyizibwa ku kutambuza amawulire ag’amaloboozi. Ku mutendera guno, eddoboozi liddamu okukolebwa nga likyusa siginiini y’amasannyalaze mu kukankana okw’ebyuma okw’emizindaalo egy’amasannyalaze. Omulimu omukulu ogw’emizindaalo gya sinema awaka ge maloboozi ag’amaanyi ag’omutindo ogwa waggulu aga 3D. Kino kinnyonnyolwa nti tewali muzindaalo na gumu oguzimbibwa mu ttivvi, ebyembi, guwa eddoboozi n’amaloboozi agazingiramu sinema z’awaka ze zigulibwa. Enkola y’emizindaalo nnyangu nnyo. Acoustics yonna erimu omubiri, emizindaalo 2-4 n’ebyuma ebisengejja amasannyalaze. Ebisembayo bikola okwawula emikutu gy’amaloboozi wakati w’emizindaalo. Emizindaalo egy’amaanyi nagyo girimu amplifier ezimbiddwamu.

Acoustics mu mbeera yonna ey’obudde

Emizindaalo egy’obudde bwonna gikozesebwa ebweru – mu bifo ebiggule, gazebo, n’ebirala Zirina omutindo ogweyongedde ogw’obukuumi okuva ku bunnyogovu n’ebbugumu erisukkiridde. Ng’etteeka bwe liri, ziteekebwa wansi w’ekisenge.

Akasolya

Emizindaalo egyateekebwa ku mwaliiro gye gitwalibwa ng’egisinga obutalabika. Zikozesebwa mu bifo eby’obusuubuzi ne ofiisi, amayumba n’ebirala.

bbugwe ayingidde mu kisenge

Emizindaalo egy’omu bbugwe (zombi eziri mu bbokisi n’ezitali mu bbokisi) ngeri nnungi ey’okukolamu amaloboozi ag’okwetooloola ekifo kyo eky’awaka nga totaataaganyizza kifo.

Enkola z’emizindaalo ezikola ku katemba w’awaka

Active acoustics presupposes okubeerawo kwa amplifier / amplifiers ezimbiddwamu, nga / ezisooka okulondebwa obulungi era ne zisengekebwa omukozi. Mu active acoustics, twawula wakati w’emizindaalo egya wireless ne active monitors.

Emizindaalo egya waya ne wireless

Ekika kino eky’amaloboozi kisalibwawo engeri emizindaalo gye giyungiddwamu.

Abalondozi abakola

Active oba studio monitors zitera okuba ez’engeri bbiri nga zirina woofers ne tweeters. Omulimu gwabwe omukulu kwe kutambuza amaloboozi awatali kussaamu langi oba okukyusakyusa.

Empagi z’amayembe

Emizindaalo gy’amayembe nagyo gyawulwamu, ng’eddoboozi teriva butereevu ku muzindaalo, wabula nga liyita mu jjembe eriteekebwa okumpi. Emizindaalo egy’engeri eno girina obuwulize obw’amaanyi n’obutereevu bw’obusannyalazo bw’amaloboozi.

Emizindaalo egy’amasannyalaze

Ekika ky’emizindaalo kino kyawukana ku birala kubanga mu kifo ky’emizindaalo, wano ekozesebwa firimu ennyimpi, ng’egoloddwa wakati wa kondakita 2, nga kuliko siginiini y’amasannyalaze eya firikwensi z’amaloboozi. Kondakita ziweebwa vvulovumenti okuva ku mutimbagano. Olw’enkolagana eno ey’ennimiro z’amasannyalaze ezitakyukakyuka n’ezikyukakyuka, firimu ekankana. Dizayini eno egaba obulagirizi bw’amaloboozi obutuufu, ekiyinza okutwalibwa ng’ekirungi n’ekibi.

empagi eziriko ebisenge (planar columns).

Era ekozesa firimu mu kifo ky’emizindaalo. Naye obutafaananako kika kya maaso, mu maloboozi aga pulaani, okukankana kwa firimu kutondebwa mu kifo kya magineeti ekitakyukakyuka. Bwe kityo, okutondawo eddoboozi erifaananako n’eryo eryayogeddwako emabegako.

Ebintu ebiyitibwa Subwoofers

Nga tugamba nti subwoofer tutegeeza emizindaalo egiddamu okufulumya amaloboozi ga frequency eza wansi, ebiseera ebisinga okuva ku 20 Hz.

Subs ezikola

Active woofers zirina amplifier ezimbiddwamu ne active crossover.

Subwoofer ezitali za kukola

Passive subwoofers tezirina amplifier ya maanyi. Era nga eyungibwa ku amplifier ey’ebweru mu parallel.

Ebikwata ku by’ekikugu

Ekimu ku bipimo ebisalawo omutindo gw’amaloboozi g’emizindaalo ye data ey’ekikugu ey’ekyuma kino:

1. Parameter esooka ye maanyi g’emizindaalo . Eddoboozi eddungi lijja kuweebwa emizindaalo egy’amaanyi ga watts 100 oba okusingawo. Era amaanyi g’ebyuma gye gakoma okuba amangi, n’obusobozi bwabyo gye bukoma okuba obunene.
2. Maximum sound pressure , mu ngeri endala, amaanyi agasinga obunene agakkirizibwa.
3. ebanga lya frequency . Subwoofer etera okuvunaanyizibwa ku frequency okuva ku 20 okutuuka ku 120 Hz.
4. Nga balina tekinologiya . Parameter eno y’evunaanyizibwa ku ddoboozi ly’eddoboozi.
5. Dyaamu y’emizindaalo ne dizayini ya kabineti . Parameters zino era okusinga zisalawo omutindo gw’amaloboozi ku kigero ekinene.

Acoustics ey’ekikugu

Mazima ddala waliwo enjawulo ennene wakati w’amaloboozi ag’awaka n’ag’ekikugu. Emizindaalo gyonna egy’ekikugu gikozesa active circuits, ekigiwa enkizo ey’amaanyi ku passive speakers:

1. Mu by’amaloboozi eby’ekikugu, buli muzindaalo waliwo ebyuma ebigaziya amaanyi ebiwerako, kwe kugamba, omugatte gw’amaloboozi amangi gwe gukozesebwa, ekintu ekitali kya bulijjo nnyo mu kukozesebwa awaka.
2. “Amaanyi” galongoosebwa era gakola mu bbandi ya frequency enfunda. Bino byonna bikendeeza ku kukyusakyusa okuyinza okubaawo, bitereeza eddoboozi okutwaliza awamu n’okukendeeza ku ssente z’ebyuma.
3. Okukyusakyusa kwa intermodulation nakyo kiggyibwawo olw’obutabaawo bisengejja bya passive high-current.
4. Olw’obutabaawo bisengejja bya crossover, omugugu gwa amplifier nagwo gulongoosebwa.
5. Okukendeeza (damping) kwa amplitude y’okuwuuma (oscillation amplitude) kulongoosebwa.

Mu ngeri endala, amaloboozi ag’ekikugu gakwata ku kuwa eddoboozi ery’olubereberye awatali kukyusakyusa kwonna.

Ebbaluwa! Ebyembi, si acoustics zonna eza situdiyo nti zisobola okuwa eddoboozi ery’ekikugu erisuubirwa. N’olwekyo kirungi okugula emizindaalo okuva mu bika ebyo ebyagezesebwa edda ekiseera okugeza Genlec.

Ebisale by’emizindaalo egy’ekikugu biva ku ddoola 2,000 okutuuka ku ddoola 12,000.

Amaloboozi g’awaka

Enjawulo enkulu wakati w’amaloboozi g’abakozesa n’ag’ekikugu kwe kukyusa sitayiro yaabwe ey’ekitongole, so si ddoboozi ery’olubereberye erirongoofu awatali kukyusakyusa. Kale, okugeza, brand “Harman” ejja kuwulira eddoboozi erikambwe, “Musical Fidelity” – “golden mean”, ne brands z’e Japan – swamped bass.

Emizindaalo gya Wireless Home Theatre

To connect a classic home theatre , ekozesebwa ne mu kisenge ekitono, ojja kwetaaga obutakka wansi wa mita 20-30 eza waya y’emizindaalo. N’olwekyo ekimu ku bizibu ebikulu ebya DC ye waya. Mu nsonga eno, abakola DC baatandika okukola layini zaabwe ez’ebyuma ebitaliiko waya. Ziyungibwa nga ziyita mu Bluetooth oba Wi-Fi.

Waliwo ebika bibiri eby’okuyungibwa okutaliiko waya okw’emizindaalo gya DC:

• okuyungibwa kwa wireless ku mizindaalo gy’emabega gyokka (Surround);
• okuyungibwa kwa wireless ku mizindaalo gyonna egy’enkola.

Wabula okussa mu nkola omukutu gwa wireless ogw’emikutu mingi ogw’ekifo eky’okwesanyusaamu si nkola nnyangu. Kikwatagana ne:

• ensengeka nnyingi ez’enjawulo ez’emikutu mingi ezeetaaga processor ey’amaanyi ne decoders;
• interfaces ez’enjawulo ezizibu okugatta mu AU;
• obwetaavu bw’okukwataganya mu bujjuvu enkola y’ennyiriri zonna.

System acoustics 5.1 oba still 7.1 – ekisinga obulungi

Bwe tuba twogera ku home theatre, olwo ekibuuzo kijja kujja ddala, format ki eya acoustics esinga. Enkola ya classic ye nkola ya 5.1, nga ennamba “5” eraga omuwendo gw’emizindaalo, “1” – omuwendo gwa subwoofers. Mu ngeri y’emu, emizindaalo gyanjulwa mu ngeri y’emizindaalo 1 egy’omu makkati, emizindaalo 2 egy’omu maaso (egiteekeddwa ku ludda olwa ddyo ne kkono olw’abawuliriza / abawuliriza ku ddaala ly’amatu) n’emizindaalo 2 egy’emabega (egiteekeddwa emabega oba waggulu w’omutwe).

Emisingi gy’okulonda

Bw’oba ​​olonda acoustics ku home theater, kikulu okulowooza ku parameters z’ekisenge n’emirimu ekyuma gye kirina okukola. Kya lwatu, tetwerabira ku kika ky’okukulembeza eky’okuteeka amaloboozi era tetulagajjalira data ya tekinologiya ey’ebyuma. Okulonda acoustics for home theatre – nga brands zikola emizindaalo egy’omulembe era egy’omutindo ogwa waggulu ne subwoofers: https://youtu.be/MPRZgPQsLKk

Okuyunga enkola y’emizindaalo 5.1, 7.1 – engeri y’okusengeka emizindaalo gya sinema awaka

Okuyunga Emizindaalo gya Home Theatre

Bw’oba ​​oteeka enkola ya sinema y’awaka, ky’olina okusooka okukola kwe kuteeka emizindaalo gyonna mu butuufu, ng’otunuulira byonna ebiteesebwako. Ekiddako, tuyunga emizindaalo ku lisiiva. Kino okukikola, kozesa cable ejja ne threaded ne push connectors. Era tuyunga ku biyingiza amaloboozi, nga essira tulitadde ku bubonero obukwatagana (CENTER – ku mizindaalo egy’omu makkati, FRONT – ku maaso, SURROUND – ku mabega ne SUBWOOFER – ku subwoofer, mu kulondako). Engeri y’okuteekawo enkola ya sinema awaka ng’olina enkola y’emizindaalo egy’omutindo gwa hi-fi – okuteeka emizindaalo emituufu ku nkola ya 5.1: https://youtu.be/YPsUVh8WvGw

Okuyunga acoustics ku kompyuta

Osobola n’okuyunga emizindaalo ku kompyuta. Bwe tuba twogera ku mizindaalo egy’obutakola, olwo ebyuma tubiyunga nga tukozesa waya ya Mini Jack oba waya 2 eza RCA nga tukozesa adapter (laba data ey’ekikugu ey’emizindaalo). Ku PC, audio input ewandiikiddwa mu langi ya green. Okuyunga amaloboozi agakola ku kompyuta nakyo kisoboka. Kaadi z’amaloboozi ezimbiddwamu ku PC ez’omulembe zisobozesa wadde enkola ya emikutu 7 okukozesebwa. Ekikulu kwe kumanya ensengeka za langi. Kale, audio input ya orange ya mizindaalo egy’omu makkati ne subwoofer, eya green ya mizindaalo egy’omu maaso, eddugavu ya mizindaalo gya mabega, enzirugavu ya side, eya bbulu ya linear connection ya an gitala y’amasannyalaze, omuzannyi n’ebirala, ate eya pinki ya kuyunga mayirofooni.
