Isipikha esisebenza kahle kakhulu emotweni: Umhlahlandlela womthwalo wemfanelo wekhwalithi yomsindo kanye nokuxazulula izinkinga
"Embusweni womsindo" wesistimu yomsindo wemoto, isikhulumi esinamaza aphezulu ngokungangabazeki "singumthakathi wemininingwane". Ububanzi bemvamisa obungatholwa yizindlebe zabantu buphakathi kuka-20Hz no-20kHz. Izikhulumi ezimaphakathi nezingaphansi zivame ukuba nobunzima bokuphinda ngokunembile amanothi athambile angaphezu kuka-10kHz, kodwa isikhulumi esimaza aphezulu senzelwe ngqo ukugcwalisa lesi sikhala. Sizinikele ekubuyiseleni izimpawu zemvamisa ephezulu, ngebanga lemvamisa elihlanganisa u-5KHz - 20KHz, futhi singaveza ngokunembile imisindo yezinsimbi zomculo, umoya wamazwi abantu, kanye nokukhanya kwezinsimbi zomculo ezinezintambo, okwenza ulwazi lokulalela lomculo lube sobala futhi lube nobukhulu obuthathu. Ngaphandle kokubamba iqhaza kwesikhulumi esimaza aphezulu, umculo ubuyoba njengomzimba ongenawo umphefumulo, uzwakale ungathandeki futhi ungacacile, futhi kungenzeka ukuthi ulahlekelwe umphumela wawo wokulinganisa lapho ushayela ngesivinini esiphezulu.
Ngokombono wesakhiwo, izikhulumi zezimoto ezisezingeni eliphezulu kakhulu ziwuhlobo lwe-dome, zihlukaniswe ngamayunithi e-dome amahle kanye namayunithi e-dome angemahle. Iyunithi ye-dome enhle ine-engeli ebanzi yokusabalala evundlile, okuvumela indawo ebanzi ngaphakathi kwemoto ukuzwa ngokucacile imininingwane yemvamisa ephezulu; iyunithi ye-dome engemahle ine-engeli encane yemisebe evundlile kodwa inekhwalithi yomsindo ohlanzekile futhi ingaphatha amandla amakhulu^ Izinto ze-diaphragm zithinta ngqo izici zokukhipha umsindo. I-dome eqinile (i-aluminium alloy, i-titanium alloy, njll.) inesinqumo esiqinile futhi ifanelekela ukwethulwa okunamandla kwemiphumela yomsindo womculo we-pop kanye nefilimu; i-dome ethambile (ifilimu ye-silicone, ifilimu yesilika) inekhwalithi yomsindo othambile futhi ifanelana kahle nomculo we-classical kanye namazwi^
Indawo yokufaka ibalulekile ekusebenzeni kwezikhulumi ezisebenzisa imvamisa ephezulu. Ukuqinisekisa ukuthi insimu yomsindo isezingeni elifanayo nendlebe yomuntu nokudala indlela yokudlulisa umsindo enembile, ivame ukufakwa ku-A-pillar, ngaphezu kwedeshibhodi, noma emnyango wemoto. Lokhu kuhlelwa kwenza imininingwane yemvamisa ephezulu idluliselwe ngqo endlebeni ngaphandle kokulahlekelwa, okwenza ingaphakathi lemoto libonakale njengehholo elincane lekhonsathi. Abanikazi bezimoto abaningi bangaguqula ngokuphelele uhlelo lomsindo wemoto lokuqala ngokumane bangeze izikhulumi ezisebenzisa imvamisa ephezulu ze-membrane yesilika. Amanothi ashelelayo e-violin abonakala ngokucacile, futhi umoya wezwi lowesifazane ubonakala phambi kwezindlebe zabo. Umuzwa wokuzungeza nokucwiliswa uthuthukiswa kakhulu.
Kodwa-ke, lo "mhlinzeki wekhwalithi yomsindo" angabhekana nezinkinga zokungasebenzi kahle, izinkinga ezivamile zifaka phakathi ukungabikho komsindo, umsindo ophikisiwe, ivolumu ephansi kakhulu noma umsindo wangemuva, njll. Ukuze kuxazululwe inkinga, isinyathelo sokuqala ukuhlonza ngokunembile imbangela yokungasebenzi kahle.
Uma isipikha esinomsindo ophezulu sithule, ungaxazulula inkinga ngokulandela ukulandelana "kwamandla - uxhumano - izilungiselelo - amadivayisi". Okokuqala, hlola ukuthi i-fuse yesistimu yomsindo ivuthile yini, nokuthi amatheminali okuxhuma amandla aphephile futhi angenawo yini umhlwa; bese uhlola izintambo ze-RCA lily-head kanye nezintambo zesipikha ukuze ubone ukuthi zikhululekile noma zi-oxidized, bese uhlola ukuthi ingxenye ebhobokile yezintambo zesipikha somnyango iphukile yini ngenxa yokuvulwa nokuvalwa okuphindaphindiwe komnyango; okulandelayo, qinisekisa ukuthi ivolumu yesamukeli somsindo ingu-zero, uma iswishi yokuthulisa ivuliwe, nokuthi imodi yokukhipha isethwe ngendlela engalungile; ekugcineni, sebenzisa i-multimeter ukukala ukumelana kwesipikha. Ububanzi obujwayelekile kufanele bube ngu-3.2 - 4.5 Ω. Uma ukufundwa kubonisa ukungabi namkhawulo noma kuseduze no-0 Ω, kubonisa ukuthi iyunithi yesipikha yonakele.
Uma umsindo uphambene noma kukhona imisindo, kungenzeka kakhulu ukuthi isikhulumi ngokwaso sinephutha. Ukulimala kwe-diaphragm kuyimbangela evamile. I-diaphragm yesipika esisebenza ngesivinini esiphezulu incane futhi ithambekele ekuphukeni ngenxa yemiphumela yangaphandle noma ukushisa ngokweqile. Umonakalo omncane ungalungiswa ngeglue yesipika yobungcweti, kodwa umonakalo omkhulu udinga ukushintshwa kwe-diaphragm. Kunconywa ukuthi kwenziwe uchwepheshe ukuqinisekisa ukufakwa okuyisicaba. ^ Ukushiswa noma ukujikeleza okufushane kwe-voice coil nakho kungabangela imisindo engajwayelekile. Ukulinganisa inani lokumelana nge-multimeter kungasiza ekunqumeni lokhu. Ukufaka esikhundleni se-voice coil kudinga ukunemba okuphezulu kakhulu, futhi kunconywa futhi ukuyiyisa esitolo sokulungisa sobungcweti. ^ Ngaphezu kwalokho, izintambo ezikhululekile, ukuxhumana okubi, noma ukuphazamiseka nakho kungabangela umsindo emsindweni wejubane eliphezulu. Hlola ngokucophelela imigqa yokuxhuma, hlanza izixhumi ezihlanganisiwe, bese ushintsha imigqa eyonakele uma kudingeka.
Kukhona futhi amaphutha athile ayenzeka ngezikhathi ezithile. Lokhu kuhlobene kakhulu nokuxhumeka kwemigqa. Isibonelo, ukuxhumana okungekuhle ezindaweni zokuxhuma zezintambo, ukungasebenzi kahle kokuxhumana kwezinkinobho zesipika, noma izinkinga ngama-relay namayunithi okulawula. Isimo sokuxhumeka komugqa ngamunye kanye nezimo zokuxhumana kudingeka kuhlolwe ngayinye ngayinye. Kwezinye izimo, izingxenye ezifanele zidinga ukushintshwa.
Ukulungiswa njalo kungandisa ngempumelelo isikhathi sokuphila kwesipikha esinomsindo ophezulu. Gwema ukudlala ngomsindo ophezulu isikhathi eside ukuze uvimbele isipikha ukuthi singagcwali ngokweqile; lapho uhlanza ingaphakathi, ungafafazi uketshezi ohlelweni lomsindo; sebenzisa ithawula elomile noma i-water wipe ekhethekile ukuze usule uthuli, bese uvula amafasitela ukuze umswakama uphele; hlola njalo ukuxhumana kwezintambo ukuqinisekisa ukuthi akukho ukuxega noma ukugqwala.
Nakuba isipikha semoto esinomsindo ophezulu sincane, "siyifasitela lomphefumulo" lesistimu yomsindo. Ukuqonda umsebenzi wayo kanye nokwazi izindlela zokuxazulula izinkinga nokulungisa kungaqinisekisa ukuthi yonke ingoma edlalwa ngaphakathi emotweni icacile futhi iyathandeka, okwengeza injabulo eyengeziwe yokuzwa ohambweni lokushayela.
