Ungayibona kanjani ihedisethi enhle kakhulu?

Izinzuzo kanye nokubi kwehedisethi akunqunywa izici zangaphandle.Ukusetshenziswa kwezinto ezithile kanye nezakhiwo akumeleli lutho.Idizayini yehedisethi enhle kakhulu iyinhlanganisela ephelele yama-electroacoustics yesimanje, isayensi yezinto ezibonakalayo, i-ergonomics kanye ne-acoustic aesthetics—— Ukuhlolwa kwama-Earphone.

Ukuze kuhlolwe ihedisethi, sidinga ukudlula ezivivinyweni eziqondile kanye nokulalela ngokuzithoba ngaphambi kokuba sifinyelele isiphetho.Ukuhlolwa okuhlosiwe kwama-earphone kufaka phakathi ijika lokuphendula imvamisa, ijika le-impedance, ukuhlolwa kwegagasi lesikwele, ukuhlanekezela kwe-intermodulation, njll.

Namuhla, sixoxa kuphela ngokuhlola okulalelayo kwama-earphone, okuyisinyathelo esidingekayo ukuze sikhethe ama-earphone.

Ukuze sihlole kahle umsindo wama-earphone, kufanele siqale siqonde izici zomsindo wama-earphone.I-earphone inezinzuzo ezingenakuqhathaniswa zesipikha, ngokuhlanekezela kwesigaba esincane, impendulo yefrikhwensi ebanzi, impendulo enhle yesikhashana, imininingwane ecebile, futhi ingabuyisela izwi elithambile nelingokoqobo.Kodwa ama-earphone anezinkinga ezimbili.Ukukhuluma ngokuqondile, lezi yizici ezimbili zama-earphone, ezinqunywa isikhundla sazo somzimba esihlobene nomzimba womuntu.

Isici sokuqala "umphumela we-headphone" wama-headphone.

Imvelo ye-acoustic eyenziwe ngama-earphone ayitholakali emvelweni.Amagagasi omsindo emvelweni angena emgodini wezindlebe ngemva kokuxhumana nekhanda nezindlebe zomuntu, futhi umsindo okhishwa ama-earphone ungena ngokuqondile emgodini wezindlebe;Amarekhodi amaningi enzelwe ukudlalwa kwebhokisi lomsindo.Umsindo nesithombe kutholakala kulayini wokuxhuma wamabhokisi omsindo amabili.Ngenxa yalezi zizathu ezimbili, lapho sisebenzisa ama-headphones, sizozwa umsindo nesithombe esakhiwe ekhanda, okungezona ezemvelo futhi kulula ukubangela ukukhathala."Umphumela we-headphone" wama-earphone ungathuthukiswa ngokusebenzisa izakhiwo zomzimba ezikhethekile.Kukhona futhi isoftware eminingi yokulingisa inkundla yomsindo nehardware emakethe.

Isici sesibili imvamisa ephansi yehedisethi.

Imvamisa ephansi ephansi (40Hz-20Hz) kanye ne-ultra-low frequency (ngaphansi kuka-20Hz) ibonwa ngumzimba, futhi indlebe yomuntu ayizweli kulawa maza.I-earphone ingakwazi ukukhiqiza kabusha i-frequency ephansi ngokuphelele, kodwa ngenxa yokuthi umzimba awukwazi ukuzwa i-frequency ephansi, kuzokwenza abantu bazizwe sengathi imvamisa ephansi ye-earphone ayanele.Njengoba indlela yokulalela yama-earphone ihlukile kweyezipikha, ama-earphone anendlela yawo yokulinganisa umsindo.Imvamisa ephezulu yama-earphone ngokuvamile iyathuthukiswa, okunikeza abantu umuzwa wokulinganisela komsindo ngemininingwane ecebile;Ihedisethi enefrikhwensi ephansi eyisicaba ngokuvamile yenza abantu bazizwe sengathi imvamisa ephansi ayanele futhi izwi lincane.Ukuphakamisa kahle imvamisa ephansi kuyindlela evamile esetshenziswa i-headset, engenza umsindo we-headset ubonakale ugcwele futhi imvamisa ephansi ijulile.Ama-earphone alula nama-earplugs yizindlela ezisetshenziswa kakhulu.Zinendawo encane ye-diaphragm futhi azikwazi ukukhiqiza kabusha amaza aphansi ajulile.Imiphumela eyanelisayo yemvamisa ephansi ingatholwa ngokuthuthukisa imvamisa ephansi emaphakathi (80Hz-40Hz).Umsindo wangempela awumuhle ngempela.Lezi zindlela ezimbili ziyasebenza ekwakhiweni kwama-earphone, kodwa okuningi akwanele.Uma imvamisa ephezulu nefrikhwensi ephansi ithuthukiswa ngokweqile, ibhalansi yomsindo izobhujiswa, futhi i-timbre evuselelwe izobangela kalula ukukhathala.Imvamisa emaphakathi iyindawo ebucayi yama-earphone, lapho ulwazi lomculo luningi kakhulu, futhi kuyindawo ebucayi kakhulu ezindlebeni zomuntu.Idizayini yama-earphone iyaqaphela mayelana nefrikhwensi emaphakathi.Amanye ama-earphone anezinga eliphansi anebanga lokuphendula lemvamisa elinganiselwe, kodwa athola i-timbre ekhanyayo nebukhali, i-turbid nomsindo onamandla ngokuthuthukisa amasegimenti aphezulu naphansi wefrikhwensi emaphakathi, okudala inkohliso yokuthi amafrikhwensi aphezulu naphansi mahle.Ukulalela ama-earphone anjalo isikhathi eside kuzozizwa kuyisicefe.

Umsindo we-earphone omuhle kakhulu kufanele ube nezici ezilandelayo:

1. Umsindo umsulwa, awunakho "ukuhayiza", "buzz" noma "bhoo".

2. Ibhalansi inhle, i-timbre ayilokothi ikhanye kakhulu noma ibe mnyama kakhulu, ukusatshalaliswa kwamandla kwamafrikhwensi aphezulu, aphakathi nendawo naphansi kufana, futhi ukuhlanganisa phakathi kwamabhendi okuvama kungokwemvelo futhi kubushelelezi, ngaphandle kokuphazima kweso kanye ne-burr.

3. Ukunwetshwa kwefrikhwensi ephezulu kuhle, kuthambile futhi kubushelelezi.

4. I-low frequency diving ijulile, ihlanzekile futhi igcwele, iyanwebeka futhi inamandla, ngaphandle kokuzizwa ukukhuluphele noma kuhamba kancane.

5. Ukuhlanekezela kwefrikhwensi ephakathi kuncane kakhulu, kusobala futhi kufudumele, futhi izwi linomusa futhi lingokwemvelo, liwugqinsi, linozibuthe, futhi alileqisi imisindo yamazinyo nekhala.

6. Amandla amahle okuhlaziya, imininingwane ecebile, namasignali amancane angadlalwa kabusha ngokucacile.

7. Ikhono elihle lokuchaza inkundla yomsindo, indawo yomsindo evulekile, ukuma kwensimbi okunembile nokuzinzile, ulwazi olwanele emkhakheni womsindo, akukho umuzwa ongenalutho.

8. I-Dynamic ayinakho ukucindezelwa okusobala, umuzwa omuhle wejubane, akukho ukuhlanekezela noma ukuhlanekezela okuncane ngevolumu ephezulu.

Ihedisethi enjalo ingaphinda idlale kahle noma yiluphi uhlobo lomculo, ngokwethembeka okuhle nomuzwa womculo.Ukusetshenziswa isikhathi eside ngeke kubangele ukukhathala, futhi umlaleli angagxila emculweni.
