Ungayikhetha kanjani i-subwoofer esebenzayo ne-passive yetiyetha yasekhaya

Namuhla sizokhuluma ngohlelo lwesipikha olukhiqiza imisindo ephansi kakhulu ohlelweni lwetiyetha yasekhaya – i-subwoofer. Sizokhuluma ngezinhlobo nezici zobuchwepheshe zamadivayisi, sichaze amamodeli aphumelele kakhulu, wabelane ngemiyalo yokuxhuma, ukumisa, ngisho nokuhlanganisa i-subwoofer ngokwakho.

I-Subwoofer: umqondo kanye nenhloso endaweni yaseshashalazini yasekhaya

I-subwoofer iyithuluzi elikhiqiza kabusha imisindo yefrikhwensi ephansi kakhulu – ukusuka ku-5 Hz (okungukuthi, kufaka phakathi i-infrasound). Ngesikhathi esifanayo, akuyona ikholomu ezimele, kodwa ihambisana nesistimu yomsindo.

Qaphela! Imisindo ye-low-frequency ayitholakali kahle endaweni, okungukuthi, kunzima ukunquma umthombo womsindo ngendlebe. Mayelana nalokhu, ohlelweni lwe-stereo olunezindlela eziningi, sincoma ukufaka i-woofer eyodwa kuphela. Le nketho yokumisa izokonga isikhala futhi yehlise zonke izindleko zesistimu yesipika ngaphandle kokudela ikhwalithi yomsindo. Ama-Subwoofers, njengomthetho, asetshenziswa kulezo zinhlelo ze-stereo ezenzelwe ukubuka amafilimu agcwele imiphumela ekhethekile; kanye nokulalela umculo wesimanje ocebile nge-bass. Ngenxa yalokho, sithola umsindo ogqamile futhi ongokoqobo. [id-caption id=”attachment_6621″ align=”aligncenter” width=”623″] I-

Izinhlobo zama-subs ezisetshenziswa kumathiyetha asekhaya

Ngokuphathelene ne-audio frequency amplifier, ama-woofers ahlukaniswe abe asebenzayo futhi angasebenzi.

1. I-subwoofer esebenzayo , eyaziwa nangokuthi i-woofer, ihlukaniswa ngokuba khona kwe-amplifier eyakhelwe ngaphakathi kanye ne-crossover esebenzayo. Okusho ukuthi, ihlanganisa lawo madivaysi atholakala ngokwehlukana. I-subwoofer enjalo inokuphuma komugqa nokokufaka, futhi ingathola isignali enamaza aphezulu asevele asikiwe, okungukuthi, izinga lomugqa. Kulokhu, isihlungi se-crossover asidingeki. Ama-subwoofers amaningi asebenzayo nawo anezinketho ezengeziwe zokulungisa izimo.
2. Ngakolunye uhlangothi, isipika sokwenziwa asifakelwe isikhulisi samandla. Futhi ixhuma ku-amplifier yangaphandle noma izipikha zesitiriyo eziyinhloko ngokuhambisana. Ububi obuyinhloko bokushintsha okunjalo kuwumthwalo owengeziwe kuma-amplifiers okukhiphayo, ngezinye izikhathi okunciphisa ukucindezela komsindo jikelele. Ngakolunye uhlangothi, i-crossover ye-passive endleleni esuka ku-amplifier kuya kuzikhulumi eziyinhloko nayo inomphumela omubi kuzakhiwo ze-acoustic. I-subwoofer engenzi lutho “idinga” ukuthi ifakwe, futhi ayinawo amandla okushuna asizayo.

Isikhulisi kufanele sibe namandla okungenani ngamaphesenti ayi-10-15 kune-subwoofer engenzi lutho yamandla amenyezelwe (kanye nezipikha).

Imininingwane okufanele uyinake

Lapho sikhetha i-subwoofer, sinaka izici zobuchwepheshe eziyisisekelo zedivayisi:

1. Okunye okubaluleke kakhulu ububanzi befrikhwensi . Amandla okukhiphayo ahlukaniswe ngokwemibandela abe ama-octave amaningana, okuyi-deep bass (20 – 40 Hz), medium (40 – 80 Hz) kanye naphezulu (80 – 160 Hz). Ngesikhathi esifanayo, uhla lwamamodeli amaningi luyi-40 – 200 Hz. Amafrikhwensi asuka ku-5 Hz akhiqiza imodeli eyodwa kuphela.
2. Ipharamitha elandelayo ingcindezi ephezulu yomsindo , ngamanye amazwi, umthamo omkhulu we-subwoofer.

Kuyathakazelisa ukwazi. Izinga eliphansi kakhulu elibonwa umuntu libizwa ngokuthi i-threshold of hearing. Inani layo lingu-0 dB. Okuphakeme kakhulu yi-threshold yobuhlungu – 120 dB.

1. Ukuzwela kwe-subwoofer isilinganiso sokucindezela komsindo okumaphakathi kuya ku-1 W wamandla kanye nebanga elingu-1 m. Ngokuvamile, ukuphakama kwevelu yokuzwela (dB), kuba ngcono umsindo wesistimu yesipika.
2. Imvamisa ye-Crossover . Lapha siqonda imvamisa lapho isigaba sesignali senzeka khona. Isibonelo, uma imvamisa ye-crossover ingu-90 Hz, khona-ke zonke izingxenye zesignali ezinobubanzi obungu-20 – 90 Hz zizonikezwa i-subwoofer, futhi, isignali enamafrikhwensi ngaphezu kwevelu eshiwo izothunyelwa kuzipikha ezinkulu.
3. ububanzi be – subwoofer . Idizayini ye-subwoofer ebiyelwe futhi inquma kakhulu izici ze-acoustic zedivayisi. Kunezinhlobo ezi-3 eziyinhloko zomklamo we-subwoofer dynamic bass head – i-bandpass, ivaliwe kanye ne-inverter yesigaba. Uhlobo ngalunye lunakho kokubili izinzuzo zalo kanye nokubi okuthile.

Ungayiqaqa kanjani i-subwoofer yaseshashalazini yasekhaya ukuze ilungiswe

Ukuwisa i-subwoofer noma ukunyakazisa iyunithi kungalimaza izintambo. Lokhu kuzoholela emsindweni ovungamayo uma kuvuliwe noma okunye ukungasebenzi kahle okukhulu. Ukuze kulungiswe inkinga, isistimu yesipikha sefrikhwensi ephansi izodinga ukuhlakazwa. I-oda lokuhlaziya imi kanje:

• qaqa ngokucophelela ikesi le-subwoofer;
• Susa isipika kuhlaka.

Kubonakala sengathi yonke into ilula. Kodwa lapho uhlukanisa i-sub, kubalulekile ukucabangela inani lama-nuances.

• Amakesi anoma iyiphi i-subwoofer avuleka aqine kakhulu . Ezipikhani zamanye amafemu, udonga olungemuva luboshelwe ngezikulufo ezine noma ezinhlanu. Abanye abakhiqizi abanqunyelwe kulolu hlobo lwe-fastener, futhi banamathisele izingxenye; noma sebenzisa uhlobo lokubopha “emigwaqweni”. Ngakho-ke, ukuze uqaqa icala, ungase udinge ama-screwdrivers amancane ayisicaba kanye ne-Phillips, ummese wokukhipha ingcina.

Qaphela! Vula ikesi kancane ukuze ungalimazi izintambo nokunye okungaphakathi kwe-subwoofer.

• Isipika esingaphakathi kwekesi singabuye sifakwe ngezikulufo kanye neglue . I-Panasonic subwoofers inekhebula elihlukile. Ukuhlola ubuqotho bezintambo, i-compartment ivuliwe. Kubuye kunconywe ukuthwebula indawo yezintambo ezigabeni ezihlukene zokuqaqa i-subwoofer. Lokhu kuzokwenza kube lula kakhulu inqubo yokuhlehla – umhlangano ozayo wesistimu.

Sithemba ukuthi ukubuyekezwa kwethu kusizile ukubhekana nayo yonke imibuzo ekhona.
