Indlela yokuchonga i-headset egqwesileyo?

Iingenelo kunye nokungonakali kwe-headset ayigqitywanga yimiba yangaphandle.Ukusetyenziswa kwezinto ezithile kunye nezakhiwo azimeli nantoni na.Uyilo lwe-headset egqwesileyo yindibaniselwano egqibeleleyo ye-electroacoustics yanamhlanje, isayensi yezinto eziphathekayo, i-ergonomics kunye ne-acoustic aesthetics—— Uvavanyo lwee-Earphones.

Kuphononongo lwe-headset, kufuneka sidlule kwiimvavanyo ezinenjongo kunye nokuphulaphula okuzimeleyo ngaphambi kokuba sifikelele kwisigqibo.Uvavanyo lwenjongo yee-earphones lubandakanya ijika lokuphendula rhoqo, ijika le-impedance, uvavanyo lwamaza esikwere, ukuphazamiseka kwe-intermodulation, njl.

Namhlanje, sixoxa kuphela ngovavanyo lokumamela oluzimeleyo lwee-earphones, elinyathelo eliyimfuneko kuthi ukukhetha ii-earphones.

Ukuvavanya ngokuchanekileyo isandi see-earphones, kufuneka siqale siqonde iimpawu zesandi se-earphones.I-earphone ineenzuzo ezingenakuthelekiswa nanto zesithethi, kunye nokuphazamiseka kwesigaba esincinci, ukuphendulwa kwefrikhwensi ebanzi, impendulo yethutyana elungileyo, iinkcukacha ezityebileyo, kwaye inokubuyisela ilizwi elithambileyo neliyinyani.Kodwa ii-earphone zineengxaki ezimbini.Ukuchaneka, ezi ziimpawu ezimbini zee-earphones, ezichongwa sisikhundla sazo somzimba ngokumalunga nomzimba womntu.

Inqaku lokuqala yi "headphone effect" yee-headphones.

Ummandla we-acoustic owenziwe ngee-earphones awufumaneki kwindalo.Amaza omsindo kwindalo angena kwintambo yendlebe emva kokunxibelelana nentloko yomntu kunye neendlebe, kwaye isandi esiphuma kwii-earphone singena ngqo kwi-ear ear;Uninzi lweerekhodi zenzelwe ukudlala kwibhokisi yesandi.Isandi kunye nomfanekiso zibekwe kumgca wokudibanisa weebhokisi ezimbini zesandi.Ngenxa yezi zizathu zibini, xa sisebenzisa i-headphones, siya kuziva isandi kunye nomfanekiso owenziwe entloko, okungekho ngokwemvelo kwaye kulula ukubangela ukukhathala."I-headphone effect" yee-earphones ingaphuculwa ngokusebenzisa izakhiwo ezikhethekileyo zomzimba.Kukwakho ezininzi isoftware yokulinganisa intsimi kunye nehardware kwimarike.

Into yesibini yi-frequency ephantsi ye-headset.

I-frequency ephantsi ephantsi (40Hz-20Hz) kunye ne-ultra-low frequency (ngaphantsi kwe-20Hz) ibonwa ngumzimba, kwaye indlebe yomntu ayinandaba nale mijikelezo.I-earphone inokuphinda ivelise i-frequency ephantsi ngokugqibeleleyo, kodwa ngenxa yokuba umzimba awukwazi ukuva i-frequency ephantsi, iya kwenza abantu bazive ngathi i-frequency ephantsi ye-earphone ayanelanga.Ekubeni indlela yokumamela yee-earphones yahlukile kuleyo yezithethi, ii-earphone zinendlela yazo yokulinganisa isandi.I-frequency ephezulu yee-earphones iphuculwe ngokubanzi, eyenza abantu babe nengqiqo yokulinganisela kunye neenkcukacha ezicebileyo;I-headset ene-frequency flat ephantsi ngokupheleleyo ihlala yenza abantu bazive ngathi i-frequency ephantsi ayonelanga kwaye nelizwi lincinci.Ukuphakamisa ngokufanelekileyo i-frequency ephantsi kwakhona yindlela eqhelekileyo esetyenziswa yi-headset, enokwenza ukuba isandi se-headset sibonakale sigcwele kwaye i-frequency ephantsi inzulu.Ii-earphone ezilula kunye ne-earplugs zezona ndlela zisetyenziswa ngokuqhelekileyo.Zinendawo encinci ye-diaphragm kwaye azikwazi ukuphinda zivelise amaza asezantsi asezantsi.Imiphumo eyanelisayo ephantsi rhoqo inokufumaneka ngokuphucula i-frequency low low (80Hz-40Hz).Isandi sokwenyani asiyomfuneko ukuba sihle.Ezi ndlela zimbini ziyasebenza kuyilo lwe-earphone, kodwa kakhulu akwanelanga.Ukuba i-frequency ephezulu kunye ne-low frequency iphuculwe kakhulu, ibhalansi yesandi iya kutshatyalaliswa, kwaye i-timbre evuselelweyo iya kubangela ukudinwa ngokulula.Ifrikhwensi ephakathi yindawo enovakalelo kwii-earphone, apho ulwazi lomculo luninzi kakhulu, kwaye ikwayeyona ndawo inovakalelo kwiindlebe zomntu.Uyilo lwee-earphone lulumkile malunga nefrikhwensi ephakathi.Ezinye ii-earphone ezinesiphelo esisezantsi zinoluhlu olulinganiselweyo lokuphendula rhoqo, kodwa zifumana i-timbre eqaqambileyo nebukhali, i-turbid kunye nesandi esinamandla ngokuphucula amacandelo angaphezulu nasezantsi e-frequency ephakathi, edala inkohliso yokuba iifrikhwensi eziphezulu nezisezantsi zilungile.Ukuphulaphula ii-earphone ezinjalo ixesha elide uya kuziva enesithukuthezi.

Isandi se-earphone esigqwesileyo kufuneka sibe nezi mpawu zilandelayo:

1. Isandi simsulwa, asibikho mnandi "hiss", "buzz" okanye "bhoo".

2. Ibhalansi ilungile, i-timbre ayikaze ikhanye kakhulu okanye ibe mnyama kakhulu, ukuhanjiswa kwamandla aphezulu, aphakathi kunye namaza aphantsi afanayo, kwaye ukudibanisa phakathi kwee-frequency bands kungokwemvelo kwaye kugudileyo, ngaphandle kokukhawuleza kunye ne-burr.

3. Ulwandiso lwamaza ombane aphezulu lulungile, luthambile kwaye lugudileyo.

4. I-low frequency diving inzulu, icocekile kwaye igcwele, i-elastic kwaye inamandla, ngaphandle kokuziva kunamafutha okanye ukucotha.

5. Ukugqwethwa kwamaza aphakathi kuncinci kakhulu, kucace kwaye kushushu, kwaye ilizwi linobubele kwaye lingokwemvelo, lingqindilili, lizibuthe, kwaye alizibaxi izandi zamazinyo neempumlo.

6. Amandla amahle okuhlalutya, iinkcukacha ezityebileyo, kunye neempawu ezincinci zinokuphinda zenziwe ngokucacileyo.

7. Ubuchule bokuchaza intsimi yesandi esilungileyo, indawo yesandi evulekileyo, ukubeka isixhobo esichanekileyo nesizinzileyo, ulwazi olwaneleyo kwibala lesandi, akukho mvakalelo ingenanto.

8. I-Dynamic ayinakho ukucinezelwa okucacileyo, ingqiqo yesantya esihle, akukho ukuphazamiseka okanye ukuphazamiseka okuncinci kwivolumu ephezulu.

I-headset enjalo inokuphinda idlale ngokugqibeleleyo naluphi na uhlobo lomculo, ngokunyaniseka okulungileyo kunye nomqondo womculo.Ukusetyenziswa kwexesha elide akuyi kubangela ukukhathala, kwaye umphulaphuli unokucwiliswa kumculo.
