Okuhambisa isixhobo: scheme, ubukhulu, injongo

isandisi Electrodynamic - isixhobo esiguqula isignali zombane zibe umsindo yintshukumo coil nosebenzela entsimini kazibuthe kwimagnethi osisigxina. Ngezi zixhobo thina nazo yonke imihla. Nokuba akunyulwanga ukuba fan enkulu umculo yaye musa ukuchitha usuku headphones. Izithethi baxhotyiswa iTV, oonomathotholo ngeemoto kunye phones. Indlela eqhelekileyo kuthi ngenene imbaxa yonke lweziqalelo, kwaye isixhobo wayo - umsebenzi lokwenyaniso zobugcisa zobunjineli.

Kweli nqaku, sihlolisise nemiba kwefowuni. Makhe sixubushe ezinye amacandelo esi sixhobo nokuba zisebenza njani.

indaba

Usuku ukuqala i uhambo encinane kwimbali electrodynamics njengeyabo. Abathetha uhlobo efanayo ziye zasetyenziswa ngasekupheleni imi- 20-kwinkulungwane yokugqibela. Phone Bell babesebenza umgaqo efanayo. Yavulwa inwebu ukuba edakasa endle kazibuthe kwimagnethi osisigxina. Ezi izithethi ziye iqela ethile kakhulu: igqwethwe rhoqo, ukulahlekelwa yesandi. Ukusombulula iingxaki ezinxulumene nezithethi classical, Oliver Lorge wacebisa ukusetyenziswa namava abo. esondweni wayo ihamba kwemigca. Kamva, ababini oogxa bakhe naphaya ubuchwepheshe emarikeni umsebenzisi kwaye enelungelo uyilo entsha electrodynamics, nto leyo inxaxheba kule mini.

isithethi device

Isithethi unalo isakhiwo kunokuba nzima kwaye sakhiwa nobuninzi lweziqalelo. Kulo mzobo, isixhobo isithethi (bona. Ngezantsi) lubonisa iinkcukacha ezingundoqo ngawo isithethi isebenze ngokuchanekileyo.

Acoustic izixhobo isithethi ibandakanya ezi ziqendwana zilandelayo:

• ukumiswa (okanye udini corrugations);
• Diffuser (okanye ndizayo);
• cap;
• coil ilizwi;
• core;
• inkqubo magnetic;
• diffuzoroderzhatel;
• izigqibo eguqukayo.

Xa imifuziselo ezahlukeneyo ezithethi ezahlukeneyo zingasetyenziswa iziqalelo zoyilo ezizodwa. Dynamics Classical sefowuni ebheka ngaloo ndlela.

Cinga izinto ngamnye kulwakhiwo ngamnye iinkcukacha ezingaphezulu.

enyeleni corrugations

Le element ukwabizwa ngokuba 'entanyeni ". It is a zeplastiki okanye zerabha Umqukumbelo echaza indlela electrodynamic phezu kwindawo yonke. Ngamanye amaxesha, njengokuba izinto base isicelo kunye amalaphu ezikhethekileyo zendalo, attenuating oscillations daka. Le corrugations yahlulwe nje kuphela uhlobo lwezinto apho zenziwe, kodwa imilo. Eyona ethandwayo uhlobo olunganeno - iimboniselo zabucala polutoroidalnye.

Ngu "ikhola" iwise eziliqela iimfuno, ukuthotyelwa leyo ithetha umgangatho yalo phezulu. Imfuneko lokuqala - bhetyebhetye. Le rhoqo resonant le corrugation kufuneka ibe phantsi. Imfuneko yesibini - corrugations kufuneka kuqiniswe kakuhle kwaye ikhuphe Imo enye kuphela - ngaxeshanye. Imfuneko yesithathu - ukuthembeka. "Ikhola" kufuneka aphendule ngokufanelekileyo utshintsho kwamaqondo obushushu kunye "obuqhelekileyo" ukuguga iinyembezi, lo gama kugcinwe ukwakheka kwalo ixesha elide.

Ukuphumeza ukulingana ilungileyo kwiikholam isandi esezantsi-rhoqo kusetyenziswa yerabha imfutho, kunye eliphezulu - iphepha.

diffuser

The main into ibonakala kwi electrodynamics kukho diffuser. Somlomo cone i piston leyo edakasa phezulu straight and phantsi kwaye ugcina awo-njalo uphawu (emva koku AFC) ngendlela yomgama. Ngokwandisa frequency oscillation iqalisa ukugoba diffuser. Ngenxa yoko, kukho ekuthiwa-amaza ukuma nto, nto, kukhokelela ekubeni idiphu liphuma amagophe kwigrafu. Ukunciphisa le ndlela, nabayili sebenzisa diffusers esinzima ezenziwe izinto mninzi elisezantsi. Ukuba ubukhulu isithethi intshi-12, uluhlu ezitsho iya kwahluka phakathi 1 kilohertz ngenxa ezitsho ephantsi, 3 kilohertz ukuya 16 kilohertz kunye neliphakathi ukuya phezulu.

• Diffusers ingaba nzima. Yakhiwa yodongwe okanye aluminiyam. Iimveliso ezinjalo aziboneleli ngamanqanaba zincinane Bill. Izithethi kunye cone abantamo kakhulu noogxa imali eninzi kakhulu.
• diffusers Soft enziwe ezinepolypropylene. Ezi zikhohlela zinika amaza omsindo kakhulu ethambileyo nefudumeleyo ngenxa kukufakwa ngento ethambileyo.
• diffusers Okubonisa zimele ukusilela. Yakhiwa Kevlar okanye fiberglass. Ukuphazamiseka kwavusa yi diffuser enjalo, ingaphezulu ngaphezu koko of nzima, kodwa ngaphantsi kwe zithambe.

cap

Cap kuba Iqokobhe zokwenziwa okanye inyama umsebenzi walo ongundoqo - ukhuselo kosomlomo eluthulini. Ukongeza, le chap ludlala indima ebalulekileyo ukuyilwa kwento isandi ethile. Ngokukodwa, xa udlala midrange. Ukuze kufumaneke-CAPS ezininzi nzima ukwenza imilo ngeenxa zonke, lubanike begoba okungephi. Njengokuba mhlawumbi sele ukuqonda, ezahlukeneyo izinto njengoko ixesha ngenxa yokuba ukuphumeza isandi ethile. Ikhosi lilaphu ukumitha ezahlukeneyo, ifilim, ezaqanjwa neselulosi nkqu mesh netyhidiweyo. Nevuthisayo ngexesha yena, enze ngakumbi umsebenzi we radiator. Alumuniyam okanye steel enemingxuma osusa ubushushu obugqithisileyo ukusuka coil.

wokucoca

Maxa wambi ikwabizwa ngokuba "spider". Le ilungu obalulekileyo elahliweyo phakathi cone isithethi kunye nezindlu zawo. Ingxaki washer kukugcina livakale likriwa woofers. Oku kubaluleke ngakumbi xa igumbi kukho utshintsho ngesiquphe lobushushu. Wokucoca oqondela indawo coil kunye nenkqubo ihambe yonke, yaye umsantsa magnetic yokuqala, ukuthintela ukungena uthuli. iqhoshana Classic is a incence disc setyhula. iinguqulelo Okuninzi mihla khangela ezahlukeneyo kancinci. Abanye abenzi ngabom ukutshintsha imilo corrugations ukuze ukwandisa linearity frequency kwaye zokuzinzisa ukumila puck. Oku kuyilo kuchaphazela kakhulu okuhambisa ixabiso. Le washer zenziwe of nenayiloni, okanye kuhanjwa ubhedu. Le ndlela yokugqibela, njengokuba kunjalo cap isebenza mini-radiator.

coil Voice kunye nenkqubo umazibuthe

Ngoko sifika element, leyo, enyanisweni, unoxanduva isandi ukuzala. Inkqubo Imagnethi ise isikhewu encinane kunye yesekethe magnetic kunye Ikhoyili esiguqula amandla ombane. inkqubo Magnetic ngokwako - Yindlela umazibuthe ngokohlobo namakhonkco kunye nomxholo. Therebetween ngexesha isandi yokuzala ihamba coil ilizwi. Umsebenzi ibalulekileyo abathungi - ngokudala mhlaba otsalayo efanayo kwinkqubo ngemagnethi. Ukuza kuthi ga ngoku, kubavelisi izithethi ziya zingqinisiswe ipali kakuhle kwaye ifakwe incam engundoqo yobhedu. I zangoku coil ilizwi inikezelwa ngokusebenzisa isithethi output bhetyebhetye - wire eqhelekileyo enenxeba ngaphezu ngomsonto zokwenziwa.

isimiso ukusebenza

Xa isithethi isixhobo zinokulungiswa ngayo, siye kumgaqo umsebenzi. Lo mgaqo uyasebenza ezithile malunga na ngolu hlobo lulandelayo: i yangoku aqukuqela Ikhoyili ubangela ukuba aa Incopho ukuhla ngaphakathi lo mhlaba otsalayo. Le nkqubo entrains lo diffuser, ebangela ukuba ukutshintshatshintsha kunye amaza yangoku ekubonelelwe, kwaye idala amaza alahlwayo. Le diffuser uqala nendlebe nokudala amaza omsindo, nabanako kwasephakadeni, abantu abevanga kwabantu. Bona ke ngohlobo sokuhlaba sombane idluliselwe umsindo. Ngoko ke, isandi ibonakala.

Ubuninzi kuxhomekeke Ebubanzini umphakathi Imagnethi yomhlaba kunye nesayizi isithethi. Xa ubukhulu elikhulu kwandisa umsantsa sibubona kwinkqubo Imagnethi, kunye nayo, kwaye yandisa inxenye coil olusebenzayo. Kungenxa yoko le nto izithethi compact akakwazi ukuphatha ezitsho ephantsi kuluhlu 16-250 Hz. umbundu wabo ubuncinane rhoqo 300 Hertz iqala ize iphele ngo-12,000 elilodwa. Kungenxa yoko le nto Dynamics ukutswina, xa ukuba bangene ngaphandle yesandi ukuya ubuninzi.

ukumelana zombane NOMINAL

Wire Ukunikeza zangoku coil enokumelana kunye reactance. Ukuze ubone inqanaba iinjineli ukuba yokugqibela Walinganisa rhoqo ka 1000 Hz kwi kunye nexabiso kubangele idityaniswe kweelana Ikhoyili ilizwi. Izithethi ezininzi level ukumelana ngu 2, 4, 6 okanye 8 ohms. Olu khetho kufuneka iqwalaselwe xa uthenga msindo. Kubalulekile ukuba bavumelane kwinqanaba umthwalo.

yefrikhwensi

Kuye sele wathi uninzi electrodynamics edlala kuphela yinxalenye amaza abantu ukuqonda. Yenza isithethi ubhetyebhetye ebetha uluhlu olupheleleyo 16 kwangu 20 kilohertz akunakwenzeka, ngoko ke amaza yahlulwa ngokwamaqela amathathu: ephantsi, ephakathi nephezulu. Emva koko, lo abayili waqala ukudala amandla ngokwahlukeneyo frequency nganye. Oku kuthetha ukuba woofers eziphambili ukumelana bass. Basebenza kuluhlu 25 Hz - 5 kHz. High-luyilwe ukusebenza ukungxola xa bebhiyozela (kungoko isibizo eqhelekileyo - "pill"). Zisebenza kwi kilohertz frequency uluhlu 2 - 20 kHz. unit Midrange kwi uluhlu 200 Hz - 7 kHz. Iinjineli nangoku lizama ukudala broadband isithethi ezikumgangatho ophezulu. Yeha, okuhambisa ixabiso ichasene umgangatho walo kwaye kumgwebela kuyo.

A kancinane ngayo isithethi mobile

kwizithethi ifowuni ukuba ahlukile "abadala" imifuziselo ngokwakhayo. Khangela indlela entsonkothileyo emzimbeni weselula yenzeka, ngoko iinjineli waya iqhinga kwaye bafaka linani lweziqalelo. Umzekelo, jiko baba ukugogeka, kwaye endaweni yoko wasebenzisa diffuser ndizayo. kwizithethi ifowuni xa lula kakhulu, ngoko, ukuba ulindele ukuba isandi angafanele umgangatho.

Uluhlu Ukuxhaphaka lisetyenziswa i element iingqameko kakhulu. Ngokutsho isandi sayo, nguye kufutshane izixhobo oluvela rhoqo, njengokuba umzimba ifowuni akukho ndawo eyongezelelweyo ufakelo umphakathi zamafu ngemagnethi.

Okuhambisa isixhobo kwifowuni ephathekayo kuphela ubungakanani kodwa ukungabikho geqe. ikhono le isixhobo ziphelele software. Oku kwenzelwa ukukhusela kuyilo abantetho isisiXhosa. Abaninzi ukususa lo umda ngesandla, uze ucele: "? Izithethi Kutheni ukutswina"

Kwi-avareji smart ukuseka izinto ezimbini. Omnye esezantsi, omnye zomculo. Ngamanye amaxesha kuhlanganiswa ukuze aphumeze isiphumo yesitiroyo. Enye indlela okanye omnye, ukuze kufikelelwe ubunzulu nobutyebi kwi isandi kunokuba kuphela inkqubo stereo ngokupheleleyo.
