Isithethi esisebenza kakuhle kwimoto: Isikhokelo soxanduva olusemgangathweni kunye nokusombulula iingxaki
Kwi "ubukumkani besandi" kwinkqubo yesandi semoto, isithethi esisebenza ngesantya esiphezulu ngokungathandabuzekiyo "singumthakathi weenkcukacha". Uluhlu lweefrikhwensi olunokubonwa ziindlebe zabantu luphakathi kwe-20Hz kunye ne-20kHz. Izithethi ezisebenza ngesantya esiphakathi zihlala zinobunzima bokuphinda ngokuchanekileyo amanqaku athambileyo angaphezu kwe-10kHz, kodwa isithethi esisebenza ngesantya esiphezulu senzelwe ngokukodwa ukugcwalisa esi sikhewu. Sizinikele ekubuyiseleni imiqondiso yefrikhwensi ephezulu, enoluhlu lweefrikhwensi olugubungela i-5KHz - 20KHz, kwaye sinokubonisa ngokuchanekileyo ukugqithisela kwezixhobo zomculo, umoya wamazwi abantu, kunye nokukhazimla kwezixhobo zomculo ezineentambo, okwenza amava okumamela umculo acace ngakumbi kwaye abe nobukhulu obuthathu. Ngaphandle kokuthatha inxaxheba kwesithethi esisebenza ngesantya esiphezulu, umculo ubuya kuba njengomzimba ongenamphefumlo, uvakala ungathandeki kwaye ungacacanga, kwaye kunokwenzeka ukuba ulahlekelwe yimpembelelo yawo yokubeka iileya xa uqhuba ngesantya esiphezulu.
Ngokwembono yesakhiwo, izithethi zemoto ezisebenza nge-high-fidelity ikakhulu zezohlobo lwe-dome, zahlulwe zibe ziiyunithi ze-dome ezilungileyo nezingalunganga. Iyunithi ye-dome elungileyo ine-engile ebanzi yokusasazeka ethe tyaba, evumela indawo ebanzi ngaphakathi kwesithuthi ukuba ive ngokucacileyo iinkcukacha ze-high-frequency; iyunithi ye-dome engalunganga ine-engile encinci yemitha ethe tyaba kodwa inomgangatho wesandi ococekileyo kwaye inokusingatha amandla amakhulu^ Izinto ezikwi-diaphragm zichaphazela ngokuthe ngqo iimpawu zokuphuma kwesandi. I-dome eqinileyo (i-aluminium alloy, i-titanium alloy, njl.njl.) inesisombululo esomeleleyo kwaye ifanelekile kwimbonakalo enamandla yeziphumo zesandi zomculo we-pop kunye nefilimu; i-dome ethambileyo (ifilimu ye-silicone, ifilimu yesilika) inomgangatho wesandi esithambileyo kwaye ihambelana kakuhle nomculo weklasikhi kunye namazwi^
Indawo yokufakela ibalulekile ekusebenzeni kwezithethi ezisebenzisa isandi esiphezulu. Ukuqinisekisa ukuba intsimi yesandi ikwinqanaba elifanayo nendlebe yomntu kunye nokudala indlela yokudlulisa isandi echanekileyo, zihlala zifakelwa kwi-A-pillar, ngaphezulu kwedeshibhodi, okanye emnyango wemoto. Olu lwakhiwo lwenza ukuba iinkcukacha ezisebenzisa isandi esiphezulu zidluliselwe ngqo endlebeni ngaphandle kokulahlekelwa, okwenza ingaphakathi lemoto libonakale njengeholo encinci yekonsathi. Abanini beemoto abaninzi banokuguqula ngokupheleleyo inkqubo yesandi yemoto yokuqala ngokongeza nje izithethi ezimbini ezisebenzisa isandi esiphezulu se-membrane yesilika. Amanqaku okutyibilika kwevayolin abonakala ngokucacileyo, kwaye umoya welizwi lomfazi ubonakala phambi kweendlebe zabo. Imvakalelo yokujikelezwa nokuntywiliselwa iphuculwa kakhulu.
Nangona kunjalo, lo "mboneleli womgangatho wesandi" unokuhlangabezana neengxaki zokungasebenzi kakuhle, iingxaki eziqhelekileyo ziquka ukungabikho kwesandi, isandi esigqwethekileyo, isandi esiphantsi kakhulu okanye ingxolo yangasemva, njl. Ukusombulula ingxaki, inyathelo lokuqala kukufumanisa ngokuchanekileyo unobangela wokungasebenzi kakuhle.
Ukuba isithethi esinomsindo ophezulu asithethi, ungasombulula ingxaki ngokulandela ulandelelwano lwe "power - connection - settings - devices". Okokuqala, jonga ukuba i-fuse yenkqubo yesandi ivuthuzekile na, kwaye ukuba ii-terminals zoqhagamshelo lwamandla zikhuselekile kwaye azinawo umhlwa; emva koko, hlola iintambo ze-RCA lily-head kunye neentambo zesithethi ukuze ubone ukuba zikhululekile okanye zi-oxidized na, kwaye ujonge ukuba inxalenye eneembobo zentambo yesithethi yomnyango iphukile ngenxa yokuvulwa nokuvalwa okuphindaphindiweyo kocango; okulandelayo, qinisekisa ukuba ivolumu yesamkeli sesandi yi-zero, ukuba iswitshi esithuleyo sivuliwe, kwaye ukuba imo yokuphuma isetiwe ngendlela engalunganga; ekugqibeleni, sebenzisa i-multimeter ukulinganisa ukumelana kwesithethi. Uluhlu oluqhelekileyo kufuneka lube yi-3.2 - 4.5 Ω. Ukuba ukufundwa kubonisa ukungabikho kokuphela okanye kukufutshane ne-0 Ω, kubonisa ukuba iyunithi yesithethi yonakele.
Ukuba isandi sigqwethekile okanye kukho iingxolo, kusenokwenzeka ukuba isithethi ngokwaso sinesiphako. Ukonakala kwe-diaphragm yimbangela eqhelekileyo. I-diaphragm yesithethi esisebenza rhoqo incinci kwaye ithambekele ekuqhekekeni ngenxa yempembelelo yangaphandle okanye ubushushu obuphezulu. Umonakalo omncinci unokulungiswa ngeglue yesithethi yobuchwephesha, kodwa umonakalo omkhulu ufuna ukutshintshwa kwe-diaphragm. Kucetyiswa ukuba yenziwe yingcali ukuqinisekisa ukufakwa okuthe tyaba. ^ Ukutsha okanye ukujikeleza okufutshane kwe-voice coil nako kunokubangela izandi ezingaqhelekanga. Ukulinganisa ixabiso lokumelana nge-multimeter kunokunceda ukumisela oku. Ukutshintsha i-voice coil kufuna ukuchaneka okuphezulu kakhulu, kwaye kucetyiswa ukuba uyiyise kwindawo yokulungisa yobungcali. ^ Ukongeza, iingcingo ezikhululekileyo, unxibelelwano olubi, okanye ukuphazamiseka nako kunokubangela ingxolo kwisandi esisebenza rhoqo. Jonga ngononophelo imigca yoqhagamshelo, coca i-interfaces ezixidizisiweyo, kwaye utshintshe imigca eyonakeleyo ukuba kuyimfuneko.
Kukwakho nezinye iziphene ezenzeka ngamaxesha athile. Ezi zinxulumene kakhulu noqhagamshelo lwemigca. Umzekelo, unxibelelwano olubi kwiindawo zoqhagamshelo lweengcingo, ukungasebenzi kakuhle kwee-contacts ze-speaker, okanye iingxaki ngee-relay kunye nee-control units. Imeko yoqhagamshelo lomgca ngamnye kunye neemeko zoqhagamshelwano kufuneka zijongwe nganye nganye. Kwezinye iimeko, izinto ezifanelekileyo kufuneka zitshintshwe.
Ukugcinwa rhoqo kunokwandisa ubomi besithethi esivakalayo. Kuphephe ukudlala ngesandi esiphezulu ixesha elide ukuthintela isithethi ukuba singagcwali kakhulu; xa ucoca ingaphakathi, musa ukutshiza ulwelo kwinkqubo yesandi; sebenzisa itawuli eyomileyo okanye ilaphu elimanzi elikhethekileyo ukuze usule uthuli, uze uvule iifestile ukuze umswakama uphele; jonga rhoqo uqhagamshelo lweentambo ukuqinisekisa ukuba akukho kuthamba okanye ukugqwala.
Nangona isithethi esiphakamileyo semoto sincinci, "siyifestile yomphefumlo" yenkqubo yesandi. Ukuqonda umsebenzi wayo kunye nobuchule beendlela zokusombulula iingxaki kunye nokulungisa kunokuqinisekisa ukuba yonke iculo edlalwa ngaphakathi emotweni icacile kwaye iyathandeka, yongeza ukonwaba ngakumbi kuhambo lokuqhuba.
