Dynamics kudivayisi: isikimu, usayizi, injongo

ilawudispikha Electrodynamic - idivayisi oguqula isignali kagesi ku komsindo ikhoyili ukunyakaza nge samanje kazibuthe kukazibuthe unomphela. Ngalezi amadivayisi sihlangana nsukuzonke. Ngisho noma ungeyena umlandeli omkhulu we umculo futhi ungachithi nengxenye ngosuku e-headphones. Izipikha anemisila amathelevishini, imisakazo e izimoto ngisho amafoni. Mshini evamile ngathi ngempela sonke eziyinkimbinkimbi izakhi, futhi idivayisi yayo - umsebenzi wobunjiniyela art yeqiniso.

Kulesi sihloko, sihlolisise Dynamics zedivayisi. Ake sixoxe ngezinye yezingxenye kwale divayisi nokuthi asebenza kanjani.

indaba

Usuku uqale uhambo encane ibe umlando electrodynamics icebo. NoSomlomo uhlobo ezifanayo ziye zasetshenziswa ngasekupheleni 20-yalolucwaningo kwekhulu elidlule. Ucingo Bell wasebenza osebenzisa isimiso esifana. Yavulwa ulwelwesi ehamba kazibuthe kukazibuthe unomphela. Lezi izipikha bebelokhu eziningi nemiphumela ethile engathandeki sina: imvamisa ukuhlanekezela izinto, ukulahlekelwa umsindo. Ukuze ukuxazulula izinkinga ezihambisana ngezipika classical, u-Oliver Lorge aphakanyisiwe ukusetshenziswa nelwatinchanti lwabo. esondweni lakhe eyayihamba yonkana emigqeni. Ngemva kwesikhashana, ezimbili ozakwabo ingashintshwa ubuchwepheshe emakethe umthengi kanye nelungelo lobunikazi umklamo entsha electrodynamics, okuyinto kuhileleke kuze kube yilolu suku.

kudivayisi isikhulumi

Isikhulumi has a isakhiwo kunalokho kuyinkimbinkimbi futhi yakhiwa sebuningini izakhi. Esikhathini umdwebo, idivayisi isikhulumi (bheka. Ngezansi) sikhombisa losemcoka lapho isipika isebenze kahle.

Acoustic isikhulumi apharathasi yakhiwa izingxenye ezilandelayo:

• ukumiswa (noma emaphethelweni corrugations);
• Diffuser (noma ulwelwesi);
• cap;
• ikhoyili izwi;
• core;
• uhlelo kazibuthe;
• diffuzoroderzhatel;
• iziphetho Nezimo.

Ngo onobuhle ezahlukene izikhulumi ezahlukene teluhlaka esiyingqayizivele ingasetshenziswa. Dynamics Classical zedivayisi ubukeka ngaleyo ndlela.

Cabangela izici ngamunye kwesakhiwo kabanzi.

emaphethelweni corrugations

Lo msuka ubizwa nangokuthi "collar". Kuyinto plastic noma irabha edging echaza indlela electrodynamic phezu yonke indawo. Ngezinye izikhathi, njengoba impahla isizinda isicelo ne izindwangu yemvelo ekhethekile, attenuating oscillations enamathela. I corrugations zihlukaniswe hhayi nje ngenxa uhlobo impahla okuvela ngazo zenziwa, kodwa futhi ngiwumqemane. Ethandwa kakhulu subtype - amaphrofayli polutoroidalnye.

By "collar" abeke eziningi izidingo, ukuhambisana okhuluma kukhwalithi ephezulu. Eyokuqala imfuneko - nakalula. Imvamisa resonant we corrugation kumele kube ongaphakeme. Eyesibili imfuneko - corrugations kufanele kube kahle futhi ikunikeze imodi eyodwa kuphela - ngokulinganisa. Esesithathu imfuneko - nokwethenjelwa. "Ibhande" kufanele ngokwanele ukuphendula lapho kushintsha izinga lokushisa kanye "evamile" ukuwohloka kwamangqamuzana, ngenkathi sigcina ezakheke isikhathi eside.

Ukuze kuzuzwe ibhalansi best ongaphakeme-imvamisa umsindo amakholomu esetshenziswa Izifutho iraba, kanye eliphezulu - ephepheni.

diffuser

The main into imbuthuma ku electrodynamics we diffuser. Isilawuli Isigaxa kuyinto piston esishukumisela endaweni niqonde futhi phansi igcina amplitude-imvamisa isici (ngemuva kwalokhu AFC) ngendlela eqondile. Ngokwandisa imvamisa oscillation iqala ukugoba diffuser. Ngenxa yalokhu, kukhona okuthiwa amagagasi ukuma ukuthi yena, kuholele ofaka futhi liphuma Curves igrafu. Ukunciphisa lo mphumela, abaklami basebenzisa uma liqhathaniswa nezibani stiffer eyenziwe impahla density aphansi. Uma usayizi isikhulumi 12 amayintshi, uhla amaza ke kuzohluka phakathi 1 kilohertz for imisindo ephansi, 3 kilohertz 16 kilohertz naphakathi ukuya phezulu.

• Uma liqhathaniswa nezibani kungaba ezinzima. Yakhiwa Ceramic noma aluminium. imikhiqizo enjalo ukunikeza ezingeni ezincane kunazo zonke ukuhlanekezela. Izipikha nge Izigaxa abantamo kakhulu nozakwabo ezibizayo.
• uma liqhathaniswa nezibani Soft zenziwa kwe-polypropylene. Lezi amasampula ukunikeza elithambile kakhulu futhi efudumele amaza omsindo ngenxa ukumuncwa elinama esithambile.
• uma liqhathaniswa nezibani Semi amelela ukusilela. Yakhiwa Kevlar noma-fiberglass. Ukuhlanekezelwa cuphuluza a diffuser ezinjalo, kunakunoma we kanzima, kodwa ngaphansana elithambile.

cap

Cap kuba igobolondo zokwenziwa noma izicubu futhi umsebenzi wakhe omkhulu - lokuvikeleka kwezifiso ezisemqoka ezingumphumela isikhulumi ngothuli. Ngaphezu kwalokho, cap linendima ebalulekile ekwakhiweni umsindo othile. Ikakhulukazi, uma udlala Midrange. Ukuze aqinisekise ofeleba kanzima kakhulu ukwenza round ukuma, ebanikeza goba kancane. Njengoba cishe kakade ukuqonda, tintfo letitinhlobonhlobo njengoba isikhathi ngenxa yokuthi ukufeza umsindo othile. Inkambo yindwangu impregnation ezahlukene, ifilimu, cellulose izingoma ngisho anezikhala metal. Lesi sakamuva, esikhundleni salokho, enze kakhudlwana futhi umsebenzi kurediyetha. Aluminium noma steel anezikhala kususa ukushisa okweqile kusukela ikhoyili.

Washer

Ngezinye izikhathi ibizwa nangokuthi "isicabucabu". Lena ilungu onohlonze ngokufanele phakathi Isigaxa isikhulumi kanye nezindlu zawo. Inkinga Washer iwukuhlale resonance esiqinile woofers. Lokhu kubalulekile ikakhulukazi uma ikamelo kunezinguquko okungazelelwe lokushisa. Imshini elungisa isikhundla kwekhoyili lonke ezihambayo uhlelo, futhi lelo gebe kazibuthe uvala, ekuvimbeleni ingress uthuli. Washer Classic kuyinto disc isiyingi lukathayela. izinguqulo Okuningi yesimanje sehluke kancane. Abanye abakhiqizi ukushintsha ngamabomu ukuma corrugations ukuze andise linearity imvamisa futhi ekulinganiseni ukuma puck. Lo mklamo kuthinta kakhulu intengo Dynamics. I washers zenziwa inayiloni, noma ithusi amashidi. Inketho yokugcina, njengoba kwaba njalo endabeni ka-cap uba mini-kurediyetha.

ikhoyili Voice ne uzibuthe uhlelo

Ngakho sayithola kungxenye, okuyilokho, eqinisweni, obhekene umsindo ukukhiqizwa kabusha. Uhlelo kazibuthe itholakala igebe amancane wesifunda kazibuthe kanye ikhoyili oguqula amandla kagesi. uhlelo Magnetic ngokwayo - kuyinto uhlelo uzibuthe ngesimo izindandatho core. Therebetween ngesikhathi umsindo ukukhiqizwa kabusha ezihambayo ikhoyili izwi. Umsebenzi obalulekile abaklami - ngokudala ensimini iyunifomu kazibuthe ohlelweni kazibuthe. Kuze kube yimanje, abakhiqizi izikhulumi kufanele iqinisekiswe kahle Induku eline ithiphu zethusi core. Lamanje e ikhoyili izwi ihlinzekwa ngokusebenzisa nezimo isikhulumi okukhipha - wire ezivamile nilimaza phezu intambo zokwenziwa.

Umgomo we operation

Nge isikhulumi kudivayisi ihlelwa, siya isimiso umsebenzi. Isimiso ezisebenza ebudlelwaneni simiswe ngalendlela lelandzelako: wamanje ogeleza ikhoyili kubangela ukuba perpendicular iyehla iyenyuka ngaphakathi kazibuthe. Lolu hlelo entrains le diffuser, wabangela ukuba ehla enyuka nge imvamisa wamanje enikeziwe, futhi kudala amagagasi esibhedlela. I diffuser iqala dlidliza futhi udale amaza omsindo, okungase ziqondakala indlebe yomuntu. Ziyakwazi ngesimo isignali adluliselwa amplifier kagesi. Ngakho, umsindo livela.

Imvamisa incike ukujiya cores kazibuthe kanye nosayizi isikhulumi. Ngo ezidlula emikhulu kwandisa igebe kazibuthe ohlelweni kazibuthe, futhi nalo, futhi kukhulisa ngempumelelo ikhoyili ingxenye. Yingakho izikhulumi compact abakwazi ukusingatha imisindo ephansi kule uhla 16-250 Hz. Sabo esincane embundwini imvamisa 300 Hertz liqala futhi liphethe ngesikhathi 12,000 hertz. Yingakho Dynamics kwesifuba, uma wriggle aphume umsindo esiphezulu.

Okuzisholo ukumelana kagesi

Wire kokunikeza yamanje Ikhoyili ukumelana naso futhi kwenze reactance. Ukuze kutholakale izinga wale mithandazo ke onjiniyela kulinganiswa at a imvamisa 1000 Hz futhi ukubaluleka okuholela yengezwe ukumelana ikhoyili izwi. Iningi izipikha ukumelana ileveli 2, 4, 6 noma 8 ohms. Lolu khetho kufanele kubhekwe uma uthenga-amplifier. Kubalulekile ukuba uvumelane ezingeni umthwalo.

ibhendi yokuvama

Sekuvele ukuthi iningi electrodynamics edlala kuphela ingxenye imvamisa abantu babone. Yenza isikhulumi enemisebenzi ukuthi ungadlala uhla eligcwele 16 kuya kwangu-20 kilohertz akunakwenzeka, ngakho imvamisa lahlukaniswa laba amaqembu amathathu: ongaphakeme, aphakathi nendawo kanye eliphezulu. Ngemva kwalokho, abaklami waqala ukudala Dynamics ngokuhlukile imvamisa ngamunye. Lokhu kusho ukuthi woofers ezikahle ukuze bakwazi ukubhekana nezinkinga bass. Basebenza ebangeni 25 Hz - 5 kHz. High-zenzelwe ukusebenza nokuklabalasa highs (kungakho Ibizo ezivamile - "beeper"). Basebenza kilohertz imvamisa uhla 2 - 20 kHz. Midrange iyunithi ku ezahlukene 200 Hz - 7 kHz. Onjiniyela namanje kuzanywa ukudala eliphezulu broadband isikhulumi. Maye, Dynamics intengo kuphambene izinga layo kanye akusho bathethelele ke.

Okuncane isikhulumi mobile

ezikhulumini wefoni bengafani "omdala" onobuhle ngokwakhayo. Thola indlela eziyinkimbinkimbi emzimbeni yeselula ngiyaphupha, ngakho onjiniyela waya kusiza futhi esikhundleni eziningi izakhi. Ngokwesibonelo, ohlobo lwe babe ongasanyakazi, futhi esikhundleni wasebenzisa diffuser ulwelwesi. ezikhulumini wefoni lula kakhulu, ngakho-ke, ukuba silindele ukuba kuzwakale akufanele izinga.

Ububanzi imvamisa ukuthi ungafunda i-elementi kakhulu ayisesemikhulu. Ngokusho umsindo zayo, eliseduze kumadivayisi ephezulu imvamisa, njengoba emzimbeni ifoni akukho isikhala eyengeziwe for ukufakwa obukhulu cores kazibuthe.

Dynamics divayisi iselula akuyona kuphela ubukhulu kodwa futhi ukuntuleka ukuzimela. amakhono idivayisi anqunyelwe isofthiwe. Lokhu kwenzelwa ukuvikela umklamo izikhulumi. Abaningi ukususa lo mkhawulo ngesandla ezisematheni, bese uyabuza: "? Izipikha Kungani kwesifuba"

Esikhathini smartphone isilinganiso ukusungula izakhi ezimbili ezinjalo. Omunye Elementary, omunye zomculo. Ngezinye izikhathi basuke kuhlanganiswe kuzuzwe nomphumela stereo. Ngandlela-thile, ukuba kufezeke ukujula cefe e umsindo kungaba nge-stereo uhlelo egcwele.
