Dhaqdhaqaaqa qalabka, nidaamka, size, ujeedada

samaacad Electrodynamic - qalab in badasha signal koronto galay dhawaaqa by dhaqdhaqaaqa gariiradda la hadda ah beerta a magnetic of magnet joogto ah. Iyada oo qalabka aynu la kulmi on joogta ah maalin walba. Xitaa haddii aadan taageere weyn u ah music hana ku qaataan maalin badh in headphones ah. Guddoomiye ku yihiin yaallaan telefishanno, raadiyayaasha ee baabuurta iyo xitaa telefoonada. hab caadiga ah inoo ah run ahaantii waa adag ah oo dhan ee canaasiirta, iyo qalab ay - shaqo ah oo run ah tahay injineernimada.

In this article, aragti dhaw ee dhaqdhaqaaqa qalabka. Ina keena aynu uga wada hadlaan qaar ka mid ah qaybaha qalab ay tahay iyo sida ay u shaqeeyaan.

story

Maalinta bilaabi dalxiiska yar oo galay taariikhda electrodynamics war abuurashadoodii. Guddoomiye ku ah nooca la mid ah ayaa loo isticmaalay in dabayaaqadii 20-mada ay qarnigii la soo dhaafay. Phone Bell shaqeeyay on mabda'a isku mid ah. Waxaa la shaqeysiin xuub in dugaagga duurka jooga oo magnetic of magnet joogto ah. ku hadla waxa ay ku dhamaadeen tiro ka mid ah cillado halis ah: dhabtii noqnoqoshada, khasaaraha ka mid ah dhawaaqa. Si loo xaliyo dhibaatooyinka la xiriira ku hadla classical, Oliver Lorge soo jeediyay isticmaalka ay waayo-aragnimo u gaar ah. Uu ku ambadeen waxaa guud khadadka. Wax yar ka dib, laba ka mid ah asxaabta uu ku habboon technology in ay suuqa macaamiisha iyo xiranayo design cusub oo electrodynamics, taas oo qayb ilaa maantadan la joogo.

Gudoomiyaha qalab

Gudoomiyaha waxa uu leeyahay qaab-dhismeedka halkii adag iyo ka kooban yahay hannaanka ka mid ah xubno ka. In jaantuska, qalab Afayeenka (eeg. Hoos) ayaa muujinaya tafaasiisha muhiimka by kaas oo gudoomiyaha si sax ah oo ka hawlgala.

qalab Gudoomiyaha loomana baahno ka kooban yahay qaybaha soo socda:

• ganaax (ama laayeen corrugations);
• Diffuser (ama xuub);
• cap;
• gariiradda cod;
• core;
• nidaamka magnetic;
• diffuzoroderzhatel;
• gunaanad dabacsan.

In lagu daydo oo kala duwan oo ku hadla kala duwan xubno design gaar ah loo isticmaali karaa. dhaqdhaqaaqa Qadiimiga ah ee qalabka u muuqataa jidkaas.

Ka fikir kasta oo xubno ka dhismaha shaqsi si faahfaahsan.

darafka corrugations ah

element waxaa sidoo kale loo yaqaan "collar". Waa caag ama caag qarka ah ku tilmaamay hab electrodynamic deegaanka oo dhan. Mararka qaarkood, sida wax saldhig codsatay la difaan dabiiciga gaar ah, attenuating daahan oscillations. corrugations The kala qaybsan yihiin ma aha oo kaliya by nooca wax ka taas oo ay ka samaysan yihiin, laakiin sidoo kale qaab. Hoosaadka ugu caansan - profiles polutoroidalnye.

By ah "collar" rogi dhowr ah oo looga baahan yahay, la raacayo oo ku hadla ee ay tayo sare leh. Shuruudaha looga baahan yahay marka hore - dabacsanaanta. inta jeer ee resonant of corrugation waa in ay ku yar. Shuruudaha labaad - corrugations waa in ay si fiican u xaqiijisatay iyo in la siiyo mid ka mid ah oo keliya mode - isku midka ah. shuruudda saddexaad - halaynta. "Collar" Waa in ku filan ka jawaabaan isbedel ah ee heerkulka iyo "caadi ah" xirtaan iyo jeexa, iyadoo la ilaalinayo ay qaab muddo dheer.

Si loo gaaro dheelitirka ugu fiican ee columns codka hoose ee loo isticmaalo Bufinkii caag, iyo sare - warqad.

diffuser

shayga ugu weyn ee radiating ee electrodynamics of diffuser ah. Guddoomiyaha koorta waa qalab ah oo dhaqdhaqaaqa a toosan iyo hoos iyo ilaaliyaan Ilodanimada-soo noqnoqoshada dabeecadda (halkan AFC) ee fashion toosan. By kordhaya inta jeer oscillation bilaabo in la leexiyo diffuser. Taas darteed, waxaa jira wax-u hirarka taagan in, markeeda, keeni lumo iyo kacda gooladaha garaafka. Si loo yareeyo saamaynta this, samaynta isticmaali diffusers hanashada ee wax ka mid ah mugga hooseeya sameeyey. Haddii size afhayeenka waa 12 inches, kala duwan ee mawjadaha u kala duwan yihiin inta u dhaxaysa 1 kilohertz mowjado hooseeyo, 3 kilohertz 16 kilohertz iyo kuwa dhexdhexaadka ah in ay sare.

• Diffusers noqon kartaa adag. Waxay ka samaysan yihiin dhoobada ama aluminium. waxyaabaha noocan oo kale ah waxay bixiyaan heerka ugu yar ee dhalanrog. Guddoomiye la yaqaano madax badan yihiin dhiggooda qaalisan.
• diffusers jilicsan ka samaysan yihiin polypropylene. baarka waxay bixiyaan hirarka dhawaaqa ugu jilicsan iyo diiran ay sabab u tahay nuugista ee wax jilicsan.
• diffusers Semi wakiil tanaasul. Waxay ka samaysan yihiin Kevler ama Maro adag. Dhabtii xanaajiyeen by diffuser noocan oo kale ah, uu ka badan yahay in of adag, laakiin ka hooseeya jilicsan ee.

cap

cap waa qolof ah dardaro ama unugyada kuwaas oo ugu weyn ee shaqo - ilaalinta afhayeenka Carro. Intaa waxaa dheer, furka kaalin muhiim ah in formation of dhawaaq gaar ah. Gaar ahaan, marka ciyaaro midrange. Si loo sugo u saftay ugu adag sameeyaan qaab wareegsan, wuxuuna iyaga siiyey yar gacnta ah. Sida aad u badan tahay in mar hore la fahmo, noocyo kala duwan oo qalab sida markii ay sabab u tahay xaqiiqada ah in si loo gaaro dhawaaq gaar ah. Dabcan waa dhar la dahaadhida kala duwan, filim, walxuhu cellulose iyo xataa mesh biraha. Arintaan, markeeda, oofin badan iyo shaqo hiitarka. Aluminum ama bir mesh ka saaraysaa kulaylka xad-dhaaf ah ka gariiradda.

dhaqe

Mararka qaarkood waxa kale oo loo yaqaan "caaro". Tani waa xubin ka mid ah miisaan u amro dhexeeya koorta afhayeenka iyo guryaha. dhibaatada dhaqe waa si ay u ilaaliyaan resonance ah oo deggan, waayo, woofers. Tani waxay si gaar ah muhiim, haddii qolka jiraan isbedelo lama filaan ah ee heerkulka. Dhaqe wuxuu diyaariyaa meel ka mid ah gariiradda iyo nidaamka dhaqaaqaan oo dhan, iyo farqiga magnetic xirtey, ka hortagga ingress ee ciidda. dhaqe Classic waa disc jiingado wareeg ah. More versions casriga fiirin wax yar oo kala duwan. saarayaasha qaar ka mid ah si kas ah bedesho qaabka corrugations si loo kordhiyo linearity inta jeer iyo in la dejiyo qaab reer puck ah. design Tani waxay si weyn u saameeyaa isbedbeddelka sicirka. dhaqa waxaa la sameeyey ee nylon, ama baco copper. doorasho dambe, sida in ay dhacdo furka u dhaqmo sida a mini-hiitarka.

gariiradda Voice iyo nidaamka magnet

Sidaas awgeed, waxaan helay in element ah, kaas oo, dhab ahaantii, ka mas'uul ah dhalmo codka. Nidaamka magnetic waxa uu ku yaalaa farqiga yar iyo circuit magnetic wada jir ah ula gariiradda kuweeda tamarta korontada. nidaamka magnetic laftiisa - waa hab magnet ah ee foomka of siddo oo muhiimka ah. Therebetween waqtiga dhalmo codka dhaqaaqin gariiradda cod. hawl muhiim ah samaynta - abuuro beer uniform magnetic in nidaamka magnetic. Si taas loo gaaro, saarayaasha ee ku hadla lagu xaqiijin doonaan si fiican pole oo lagu rakibay tip a asaasiga ah copper. hadda ee gariiradda codka waxaa bixisey marayo wax soo saarka Gudoomiyaha dabacsan - silig caadiga ah ku dhaawacay in ka badan dun aan dabiici ahayn.

Mabda 'hawlgalka

Iyadoo afhayeenka qalabka soocaa, Waxaynu ku soconnaa mabda'a shaqada. Mabda'a hawlgala dhaqdhaqaaqa waa sida soo socota: hadda la barwaaqaysan in gariiradda oo sababa in ay in ay dadab iyo in ay isbedbedelka gudahood duurka ku magnetic. Nidaamkan entrains diffuser ah, taasoo keentay in ay is beddelid la soo noqnoqoshada ah ee hadda ku bixisey, iyo abuuraa hirarka saaray. diffuser wuxuu bilaabaa in uu gariiro iyo in la abuuro mowjado dhawaaq, taas oo loo arko karaa by dhegta aadanaha. Waxay yihiin qaab signal koronto loo gudbiyo kordhiyo ah. Sidaa awgeed, dhawaaqa muuqataa.

Joogtaynta ku xiran tahay dhumucda ee diirkja magnetic iyo size afhayeenka. In magnitude weyn u kordhiyaa farqiga magnetic in nidaamka magnetic, oo waxaa la, iyo kordhisaa qayb wax ku ool ah gariiradda. Taasi waa sababta ku hadla is haysta ma qaadi karaan firikuwensiyada yar kala duwan 16-250 Hz ah. Waxa ay inta jeer ee xakabada ugu yar ee 300 Hertz bilaabataa, kuna dhammaataa at 12,000 Hertz. Taasi waa sababta, dhaq-hinraagid, marka aad si wriggle baxay codka ugu badan.

caabin korontada magaceed

Wire qeybinayay hadda in gariiradda uu leeyahay iska caabin ah oo reactance. Si loo go'aamiyo heerka ka mid ah injineerada waxaa dambe qiyaasay at inta jeer ah 1000 Hz iyo qiimaha ka dhalanaya lagu darayaa iska caabin ah ee gariiradda codka. ku hadla intooda badan heer iska caabin ah waa 2, 4, 6 ama 8 ohms. Doorashadan waxa waa in la tixgeliyaa marka wax iibsigu kordhiyo ah. Waxaa muhiim ah in ay ku heshiiyaan on heerka load.

band frequency

Waxaa horay loo sheegay in inta badan ee electrodynamics ciyaara kaliya qayb ka mid ah inta jeer ee ay dadku heli karo. Samee Gudoomiyaha wejiyo in ka ciyaari kara kala duwan ee ka buuxa 16 Hertz 20 kilohertz waa wax aan macquul aheyn, sidaas darteed inta jeer ee loo kala qaybiyey saddex kooxood: hoose, dhexe iyo sare. Ka dib markii in, samaynta bilaabay si ay u abuuraan dhaqdhaqaaqii si gooni gooni ah, waayo, soo noqnoqoshada kasta. Taas macnaheedu waa in woofers waa kuwa ugu fiican si ay ula qabsadaan Bass ah. Waxay ka shaqeeyaan on kala duwan oo ka mid ah 25 Hz - 5 Khz. High-waxaa loogu talagalay in la qaylinaya highs (Halkan magac guud - "beeper") shaqeeyaan. Waxay ka shaqeeyaan kala duwan oo soo noq kilohertz 2 - 20 Khz. unit Midrange kala duwan ee 200 Hz - 7 Khz. Injineerada ayaa wali isku dayaya in ay abuuraan Gudoomiyaha broadband oo tayo sare leh. Waxaa hoogtay, isbedbeddelka sicirka waa lid ku ah ay tayada iyo ma aha in uu xaq yahay.

A yar oo ku saabsan gudoomiyaha mobile

waayo, ku hadla telefoonka ee waa laga daydo "qof weyn" dhisid ah oo kala duwan. Hel hab adag ee jirka mobile waa dhalanteed, si injineerada u tageen inay trick iyo bedelay tiro ka mid ah xubno ka. Tusaale ahaan, gariiradda noqon Immobile, oo halkii ay isticmaali diffuser xuub. waayo, ku hadla telefoonka ee si weyn u fududeeyey, sidaas darteed, si filan iyaga inay ka dhawaajiyaan mana istaahisho in tayada.

kala duwan ee inta jeer in dabooli karo element ah si weyn u cidhiidhi ah. Sida laga soo xigtay xiinkeeda, isagu waa u dhaw in ay qalabka ee hirka sare, sida in jirka ah ee telefoonka ma jirto meel bannaan oo dheeraad ah loo xirxiro ee diirkja magnetic qaro weyn.

dhaqdhaqaaqa The qalab ee telefoonka mobile ma aha oo kaliya size, laakiin sidoo kale iyaduna ka mid ah madax-bannaanida. awoodaha qalab ku kooban software ah. Taas waxa loo sameeyaa si loo ilaaliyo design ee ku hadla ee. Qaar badan oo ka saar xadka this gacanta, ka dibna weydii: "? Hadla Waa maxay sababta xiiq"

In smartphone celceliska dhiso laba cunsur oo kale. A sheekaysanayo, music kale. Mararka qaarkood waxa la isku daray si loo gaaro saamaynta rikoor ah. Mid ka mid ah ama qaab kale, si loo gaaro ka qoto dheer iyo qaninimo in dhawaaqa oo keliya nidaam rikoodh buuxa noqon kartaa.
