I-home subwoofer esebenzayo: xhuma kwaye uqwalasele

I-subwoofer yenye yezona zinto zibalulekileyo kwiinkqubo zesithethi ezininzi. Ngaphandle kwakhe, intlangano yeevenkile zasekhaya ayinqabile ngokwaneleyo. Ingcamango yeklasi yale nxalenye ye-acoustics inikeza uvavanyo oluthe lucacisiweyo lwee- frequencies eziphantsi xa kuthelekiswa ne-stereosystems epheleleyo. Ukongezelela, kwezinye iinguqu ezinjalo izicwangciso zifakela izinto eziphosakeleyo zesandi, okwenza uhlaziyo oluhlambulukileyo. Okubaluleke ngakumbi, i- subwoofer esebenzayo ekhaya inempembelelo encinci kwintlangano yomzimba kwinkqubo.

Ngokuqhelekileyo, oku kuhlanganiswa kwe-compact, ukubekwa kwezinto ezingabandakanyiyo ngokwemibono yeso sandi ngumphulaphuli. Oku kubangelwe ngokuthe ngqo kwi-specificity of the propagation evela kumgangatho ophantsi, onokuthi uthathwe ngokulinganayo kungakhathaliseki ukuba ngumthombo womthombo. Nangona kunjalo, uqhagamshelo kunye nokucwangciswa kwezixhobo zifuna ulwazi ngolwazi oluthile lwezobugcisa kunye nokusebenza kwe-subwoofer.

Yiyiphi imbonakalo yesikhombi se-subwoofer esisebenzayo?

Uhlobo oluphambili phakathi kwe-subwoofers esebenzayo kunye nezixhobo ezingabonakaliyo kukufumaneka kwe- amplifier yamandla ehlangeneyo . Siyabulela kule kongeza ukuba izixhobo ngokufanelekileyo zisusa umthwalo we-frequency frequency kwi-amplifier yesikelo. Ukongeza, i sixhobo sine-crossover esebenzayo, evumela ukuhlunga kwamazinga aphezulu kunye nokwenza lula ukuchaneka kwezixhobo kunye ne-acoustics ebanzi. Kukho iinkcukacha ezongezelelweyo kwezinye iimodeli. Ngaloo ndlela, i-subwoofer yasekhaya, enexabiso elingaphezu kwama-ruble angama-30-35 amawaka, iqheleke ixhotyiswe ngemisebenzi yokulungiswa kwiimeko ezizodwa zokusebenza. Ezi azikho iimodeli ze-premium, kodwa kunoko-class ephakathi. Abameli beli candelo baxhasa ukulungiswa kwebala, ukujikelezwa kwesigaba, ukusekwa kwezikhundla zeengcingo, njl njl.

Indlela yokudibanisa i-subwoofer esebenzayo nge-amplifier?

I-amplifier ixhomekeke kwi-RCA ekhethekileyo, isenzelwe ukudibanisa i-subwoofers esebenzayo. Kweminye imodeli, kukho izibonelelo ezininzi ezinikezelwayo, eziphucula ubuchule be-acoustic zezixhobo. Ukusuka kumsebenzisi kuyimfuneko kuphela ukulungiselela i-cable ye-RCA yobude obude kwaye uyixhome kwisixhumo esifanayo. Ngokubhekiselele ekusebenziseni kwangaphandle kwezibonelelo ezimbini, eli cwangciso lincedwa ukufumana i-subwoofers yamandla enamandla exhunyiwe kwi-cable-splitter. Ngale ndlela yokusebenzisana, i-subwoofer iya kuphinda ibe nefuthe lokuqonda, kodwa oku akuyi kuba nempembelelo ebonakalayo kwizandi ezijikelezayo.

Kwakhona kukufanelekile ukugcina engqondweni ukuba ii-subwoofers zihlala zixhotyiswe ngeendlela eziphezulu nezisekhohlo eziphezulu. Kwimeko ye-acoustics, kubaluleke kakhulu ukuba ungaphumeleli ekukhetheni ikhebula. Kucetyiswa ukuba ukhethe ukhetho lwentsimbi eluqilima, oluya kugcina umthamo wesignali esiphezulu. Nangona kunjalo, ukuba usebenzisa i-subwoofer esebenzayo ekhaya ukusuka kwicandelo lohlahlo lwabiwo-mali, ngoko akukho nto ingayi kuba neyona ndawo ekunyuseni ukusebenza kwe-snap-in.

Ukuxhuma kwii-terminals terminals

Olunye uhlobo lokuxhamla luquka ukusetyenziswa kweziphene eziphambili. Kule meko, iinkqubo zesithethi zixhunyiwe kwiziphumo eziphezulu kwi-subwoofer. Ngaphambi kwamagqabantshintshi nazo zifayile eziphezulu, zibonelela umyinge we-6 dB. Olu qulunqo lunikeza ubuncinci obuncinci kuma-acoustics kwinqanaba elisezantsi. Kodwa, xa ugqiba indlela yokudibanisa i-subwoofer esebenzayo ngokusebenzisa i-terminal terminals, kubalulekile ukuqwalasela ukungabikho kweskimu esinjalo. Ukuba ukhetha imodeli echazwe ngokuxhomekeka kwii-terminals kunye nezihlungi ze-subwoofer ngokwayo, unako ukuphumeza umgangatho ophezulu womsindo kulo lonke uluhlu ngokunciphisa iiphene ze-palette ye-acoustic kwi-frequency frebit spectrum. Kodwa ekubeni iziteshi zoxhumano ziya kusebenza ngokufanayo, umthwalo wonke kwiinkqubo ziya kunyuka kakhulu.

Ukubeka i-Subwoofer yaseKhaya ngokuFa

Ukulungiswa okusisiseko kwezixhobo kwenziwa ngokuqwalasela iimpawu ze-acoustics eziphambili. Kukho nawuphi na, kuyafaneleka ukuhamba kwiiparameters eziphambili. Ukufakela ngokwayo kungatshintshwa kwiiparitha ze-audio crossover kunye neshintsho lesigaba, esiza kuxoxwa ngezantsi. Kodwa ude uqale ukucwangcisa ngqo iiparameter ze-acoustic, kufuneka uhlole umgangatho wokuxhuma kunye nokwandisa i-nodes zokuxhumeka kangangoko kunokwenzeka. Ngaphezu koko, i-subwoofers yanamhlanje kwiindawo zokuzonwabisa zasekhaya kwimida eyahlukileyo zixhotyiswe ngeendlela zokunxibelelana ezingenazintambo. Oku kuthetha ukuba izixhobo ezinjalo azidingi ukusetyenziswa kwezicwangciso zomzimba zendalo kwaye zidibaniswe ngabavoti bezonxibelelwano zomsakazo. Oko kukuthi, kufuneka kuphela ukuvumelanisa izixhobo ngokusebenzisa imodyuli yeBluetooth okanye enye inkqubo yokunxibelelana kwentambo.

Uhlengahlengiso lweCrossover

Ukusekwa kwe-crossover kwenzelwe ukusetha i-frequency spectrum yohlulo lwe-woofer. Oko kukuthi, ngoncedo lwalo mlawuli, i-subwoofers yeevenkile zasekhaya zijoliswe kuluhlu olupheleleyo lwesalathisi sokuvelisa. Kweminye imodeli, kunye nexabiso eligqithiseleyo leenqwelo-moya linikezelwa, phantsi kweyiphi i-apparatus ayikho yonke into eqondwe ngendlebe yomntu. Ixabiso eliqhelekileyo liyisithuba esiphakathi sama-80 Hz. I-Retreat kule xabiso kufuneka ibe kwiimeko apho kukho izandi ezihamba phambili. Kwimeko enjalo, kucetyiswa ukuba uhambise umlawuli ngokubhekiselele kwixesha eliphantsi.

Ukusetha kwesigaba

Ishintsho sesigaba, kwakhona, senzelwe ukuhlawulela ukuhlukana kwezikhefu phakathi kwendawo yokugcina i-subwoofer kunye nezinto zayo. Kwakhona, lo mlawuli unceda ukufanisa iimpawu ezivela kwiipatellithi ezahlukeneyo. Ulungelelanisa i-subwoofer esebenzayo ekhaya ukuba le pharamitha icebiswe ngokusemgangathweni yokudlala iziqendu zomculo ngezwi eliphantsi lomntu. Umsebenzisi kufuneka anqume ngexesha lokuphulaphula, apho isigaba sokutshintsha kwesimo sinezwi elivakalayo ngokwemvelo nangokwemvelo.

Ukupheliswa kwe-acoustic distortion ye-subwoofer

Ngenxa yezizathu ezimbalwa, nokuba ne-subwoofers ezinamaxabiso angabi naso sonke isibonelelo esilungileyo kwi-crystal. Nangona kunjalo, kwezinye iimeko, iingxaki ezinjalo ziyakwazi ukulungiswa. Ngokomzekelo, i-acoustic hum ekhethiweyo ingabangelwa kukusabalalisa kwiifowuni ze-subwoofer. Oku kunjalo nje xa umgangatho wekhebula udlala indima ebalulekileyo kwiimpawu zokusasazwa kwesandi. Ungayilungisa le ngxaki ngokuhlaziya ucingo, okanye ngokucwangcisa ulawulo lwevolumu ukufumana isandi esilungileyo esilungileyo. Ngokukodwa, i-home subwoofers ezinamandla zicetyiswa ukuba zixhunywe ngokuqala ngentambo enamandla eneRCA yekhwalithi ephuculweyo kunye nomsebenzi wokuhlola. Ngokuqhelekileyo, abasebenzisi be-subwoofers baqaphela ukuduma okukhulu, okuphazamiseka ngazo zonke iintlobo. Ukuphelisa ezo mpazamo kuya kunceda oko kuthiwa ikhefu yangoku kwikhebula.

Indlela yokukhetha i-subwoofer engcono?

Inkqubo yokufaneleka ingaba nemilinganiselo yokusebenza emyingeni kwaye, ngaphandle kokuba uxhumano olufanelekileyo, uvelise ipalali enobugcisa ehloniphekileyo. Ngaloo ndlela, i-subwoofer yamandla enamandla, enexabiso elimalunga nama-ruble angama-50-60 lamawaka, iyakwazi ukujamelana nemisebenzi yalo yokucwangcisa iifom ephantsi kwimida evunyelwe yi-acoustics. Nangona kunjalo, umphumo ofanayo uya kunikwa ngumzekelo ukusuka kwiklasi yoqoqosho, leyo, ngokwemigangatho yayo yokusebenza ephezulu, iyahambelana nekhono leyunithi yesintloko. Oko kukuthi, ukuhlawulwa ngaphezulu kwezixhobo akusoloko kulungelelanisa, njengokuba kunjalo kwiisetelliti.

Ukongeza kwiimpawu eziphambili ze-impedance, amandla kunye nebala lexesha eliqhelekileyo, ingqalelo kufuneka ihlawulwe kwakhona kwizinto zokwakha. Nangona udumo lweplastiki, imfuno ye-subwoofer eyenziwe ngamaplanga ayiyi kucima. Iingxelo zibonisa ukuba umzimba owenziweyo wezinto eziphathekayo uncedo kakhulu ekunciphiseni ukuchithwa kunye nokusabalalisa okufanayo komqondiso osebenzayo. Enyanisweni, ukhuni lulahlekelwa iplastiki ngokusebenza ngokubhekiselele kokufakela.

Isiphelo

I-subwoofer njengaleyo ifakwe kwisistim yesithethi ngenxa yesifiso soxolo oluphezulu. Ukufakelwa okusebenzayo kunye nabakukhulisi ngokubanzi ukuqinisekisa ukuphumelela kwesi siphumo. Kwaye, ngaphandle kokuba uxhulumaniso oluchanekileyo lwenziwe, i-subwoofer esebenzayo yasekhaya iya kulungelelanisa utyalo-mali kulo. Ngokutsho kwabathandwayo bomculo abasebenzisa ukucwangciswa okunjalo kunye ne-subwoofers esebenzayo, kwiingingqi ezifanayo zasemakhaya kunokwenzeka ukuphumeza amandla okuvelisa okunamandla ngezantsi. Ubungakanani benkqubo yokudalulwa kwezi mpawu ngokukodwa kuboniswe ngumgangatho woqhagamshelwano. Kwindawo yesibini izicwangciso ze-subwoofer zoluhlu lwamanqanaba.
