Jawaab Subwoofer iyo nidaamka Gudoomiyaha noqnoqoshada

Horaantii ee todobaatanaadkii iyo tiris ah oo qarnigii la soo dhaafay, waxaa la rumeysan yahay in ay ku hadla weyn ee khaanadda, si fiican. Habka casriga ah urur ee sonification ee accomodations xoogaa qaybinta kala duwan ee nidaamka Dolby wareejin subwoofer gaar ah kalsooni xoogaa ruxmado codka gudoomiyaha fiicnayn la kala duwan ku hadla, laakiin taageerayaasha ayaa ka tagay badan ilaa xad ah.

Su'aasha ah waa maxay ahaan, dhaq-Afayeenka, daryeel ah oo ku saabsan horumarinta iyo farsamoyaqaanno ka joogo marka transducers korontada galay nolosha. Waxaa jira khilaaf gaar ah in shuruudaha diffuser ah. Dhinaca mid, si loo maqli karo tayada hoose, kala duwan oo Bass ah waa inay noqdaan weyn oo ku filan iyo weyn gariiradda magnetic, on the "Bass dharbaaxay" baxo ugu xoogga. Dhinaca kale, mawjadaha sare u baahan yihiin nidaam oscillatory fudaydkii ugu badnaan iyo tiiro ugu yar.

Ugu dambayntii, horumarinta accessories loomana baahno u yimaadeen si ay xal macquul ah in safka taagan woofers wada shaqaynaya iyo kuwa lagu magacaabo "tweeter". Si kastaba ha ahaatee, haddii ay taasi waxay ka dhigan tahay "failure" dhexe ee spectrum ah, laakiin dhibaatada waa la ciribtiray by dheer ee afhayeenka saddexaad ka shaqeeya ee kala duwan this.

jawaab Frequency sidaas waafaqsan on band oo dhan la maqli karo. woofer The la qalo karaa iyada oo shaandhada dheeraad ah, laakiin si loo yareeyo load ah waxa on oo uu cimrigiinnu ku cimri dherer, waxaa la siiyaa inductance taxane-xiran a, ma dhexdhexaad transmissive iyo hirarka sare. samaacad dhexe ayaa sidoo kale u gargaartay ka haysan si ay "waffle" in Bass, iyo qaybaha signal sare. Si taas loo gaaro, in line la mid ah gariiradda iyo capacitor ah. Sida for "tweeter", ka dibna waxaa laga yaabaa in lagu bixisey oo kaliya loogu talo galay, waayo, ka band ee qiyaastii 3 Khz iyo wixii ka sarreeya, waayo, samaacad this ee taxanahan la capacitance tani waxaa ka mid ahaa.

samaacad Bass Modern waa qalab korontada adag. Dabcan ee diffuser waa wax weyn. Si aad u bixiyaan muddo dheer, waxyaabaha looga baahan yahay inay u adkeysan lahayo ku laastikada oo sidaas hayn hantida. Sida caadiga ah, emitter ku laayeen xiran yahay qaybta semicircular faraanti caag diffuzoroderzhatelem ah.

Stroke of a milimitir yar, waa in ay leeyihiin jidka cad, haddii kale cidhifka gariiradda noqon doonaa "overwritten" magnet dhexe. Waxay bixiyo dhaqe ah ee ku waxaa inta badan ka samaysan gal cusbi a cufay dhar dalool la corrugation ah annular.

Woofer - qalab-teknoolojiyad sare ee dhismaha ah waxaa loo isticmaalaa oo dhan horukaca ee la soo dhaafay in wax soo saarka polymer. diffuser waa in uu adag, ka dibna ciidanka of gariiradda la isugu gudbin doonaa guud ahaan ay dusha ku dhow goobtii, oo ay fududahay in la dardar-sifooyinka wakhtiga ay suurto gal arakayo yaraan. Si kastaba ha ahaatee, in inta badan ku hadla ugu qaalisan oo tayo sare leh, qaab daran oo ku filan, inkastoo oo dhan horumarka of technology casriga ah, warqad waxaa loo isticmaalaa sida afhayeenka ugu horeysay, kaas oo la been abuurtay in 1925 by Maraykanka gool Rice oo Kellogg.

woofer ayaa noqotay qayb muhiim ah oo design ka mid ah wax Gudoomiyaha tayo sare leh nidaamka.
