Impendulo Subwoofer kunye nenkqubo isithethi frequency

Ekuqaleni ngeminyaka yee- zenkulungwane yokugqibela, kwakukholelwa ukuba izithethi ezinkulu kwikholam, ngcono. Indlela yanamhlanje ukuya nokucwangciswa sonification of accomodations ngandlel 'ukwabiwa ezahlukeneyo inkqubo Dolby Kaka kunye subwoofer eyahlukileyo ukuzithemba ngandlel izanyazanyiswa ema isandi isithethi kangangoko nezithethi ezininzi, kodwa abalandeli baye bashiya into eninzi.

Lo mbuzo kufuneka ibe yintoni Dynamics kwisithethi, abakhathalele abaphuhlisi kunye noochwephetsha ukusuka mzuzu xa transducers electromechanical wangena ebomini. Kukho yintswela ethile iimfuno diffuser. Kwelinye icala, ukuba umgangatho sokudlala ophantsi, uluhlu bass kufuneka zibe nkulu ngokwaneleyo ezibanzi coil zemagneti, kwi "bass wakhuph 'kushiya ezininzi amandla. Kwelinye icala, ezitsho aphezulu ifuna inkqubo ndandifeketha oscillatory ubuninzi kunye inertia ubuncinane.

Ekugqibeleni, abaphuhlisi izincedisi ive baye isicombululo ubhalo kwikholam zibekwe woofers kunye ukusebenza ze-ebizwa ngokuba "tweeter". Noko ke, kule meko iba "ukungaphumeleli" phakathi kwe spectrum, kodwa le ngxaki iyapheliswa ngokuthi kongezwe isithethi wesithathu ukusebenza kweli banga.

Ngoko impendulo Ubuninzi elungelelaniswe kwi yonke band oluvakalayo. Le woofer unako esebenza ngaphandle okucoca ezongezelelweyo, kodwa ukwenzela ukunciphisa umthwalo kuyo nokulondoloza uqinile, inesixhobo inductance uthotho-elidityaniswe, kungekhona transmissive aphakathi kunye namaza eliphezulu. Ngombhobho eliphakathi nayo wakhululeka ekubeni ukuya 'waffle' ukuya bass, kwaye amacandelo umqondiso eliphezulu. Ukuza kuthi ga ngoku, ngokuhambelana nalo kwaquka coil kunye capacitor. Ke ukuba i "tweeter", ngoko ke uya kunikwa bujolise kuphela kuyo ukususela band nama-3 kHz nangaphezulu, le isandisi-zwi in ngcelele nale capacitance ifakiwe.

Modern ganga isandisi sisixhobo oluntsonkothileyo electromechanical. Le khosi ye-diffuser mkhulu kakhulu. Ukubonelela nto ixesha elide, izinto ezifunekayo ukumelana deformation elastic ngaloo ukugcina iimpahla zazo. Ngokuqhelekileyo, le emitter edge edibene ring yerabha diffuzoroderzhatelem icandelo omise.

Stroke of a iimillimitha embalwa, kufuneka ngokucacileyo indlela, kungenjalo ngohlangothi coil iya kuba "ngaphezulu" umazibuthe engundoqo. Wanika iqhoshana egxile yenziwe a Umatshini intlaka buzane Ilaphu tubing kunye corrugation thunzi.

Woofer - isixhobo eliphezulu-zobugcisa bokwakha asetyenziswa zonke inkqubela yakutshanje kwimveliso Polymer. I diffuser kufuneka ibe nzima, ngoko ke amandla Ikhoyili ziya ngapha kumphezulu wayo phantse ngephanyazo, yaye kulula nokukhawulezisa iimpawu ngexesha kunokwenzeka ukubambezeleka ubuncinane. Noko ke, uninzi izithethi kakhulu eninzi kwaye ezikumgangatho ophezulu, Isimanga, phezu kwazo zonke inkqubela zobugcisa bale mihla, iphepha lisetyenziswa isithethi sokuqala, leyo yaqanjwa baseMelika 1925 amanqaku Rice kunye Kellogg.

Le woofer kube yinxalenye ebalulekileyo yoyilo naliphi isithethi ezikumgangatho ophezulu nkqubo.
