Momwe mungadziwire mahedifoni abwino kwambiri?

Ubwino ndi kuipa kwa chomverera m'makutu sizidziwika ndi zinthu zakunja.Kugwiritsa ntchito zinthu zina ndi zomangamanga sikuyimira kalikonse.Mapangidwe amutu wapamwamba kwambiri ndi kuphatikiza koyenera kwa ma electroacoustics amakono, sayansi yakuthupi, ergonomics ndi acoustic aesthetics—— Evaluation of Earphones.

Kuti tiwunikire mahedifoni, tifunika kudutsa mayeso omwe ali ndi cholinga ndikumvetsera mwachidwi tisanafike pomaliza.Kuyesa kwamakutu am'makutu kumaphatikizapo curve frequency response, impedance curve, square wave test, intermodulation kupotoza, etc.

Masiku ano, timangokambirana za kumvetsera kwa makutu am'makutu, komwe ndi gawo lofunikira kuti tisankhe zomvera m'makutu.

Kuti tiyese bwino kumveka kwa ma earphones, choyamba tiyenera kumvetsetsa makhalidwe a phokoso la makutu.Foni yam'makutu ili ndi zabwino zosayerekezeka za wokamba nkhani, ndikupotoza kagawo kakang'ono, kuyankha pafupipafupi, kuyankha kwakanthawi kochepa, zambiri zambiri, ndipo imatha kubwezeretsa mawu osakhwima komanso enieni.Koma zomvera m'makutu zili ndi zovuta ziwiri.Kunena zowona, izi ndizomwe zili m'makutu, zomwe zimatsimikiziridwa ndi malo awo okhudzana ndi thupi la munthu.

Chinthu choyamba ndi "headphone effect" ya mahedifoni.

Malo omvera opangidwa ndi zomvera m'makutu sapezeka m'chilengedwe.Mafunde a phokoso m'chilengedwe amalowa m'mphepete mwa khutu pambuyo poyanjana ndi mutu ndi makutu a munthu, ndipo phokoso lotulutsidwa ndi ma earphones limalowa mwachindunji mumtsinje wa khutu;Zolemba zambiri zimapangidwira kusewera bokosi la mawu.Phokoso ndi chithunzi zili pamzere wolumikizira wa mabokosi awiri omveka.Pazifukwa ziwirizi, tikamagwiritsa ntchito mahedifoni, timamva phokoso ndi chithunzi chomwe chimapangidwa pamutu, zomwe sizili zachibadwa komanso zosavuta kuyambitsa kutopa."Earphone effect" yamakutu angasinthidwe pogwiritsa ntchito zida zapadera.Palinso mapulogalamu ambiri oyerekeza mawu akumunda ndi ma hardware pamsika.

Chinthu chachiwiri ndi kutsika kwafupipafupi kwa mutu.

Mafupipafupi otsika otsika (40Hz-20Hz) ndi mafupipafupi otsika kwambiri (pansi pa 20Hz) amadziwika ndi thupi, ndipo khutu laumunthu silimakhudzidwa ndi maulendowa.Zomvera m'makutu zimatha kutulutsanso ma frequency otsika mwangwiro, koma chifukwa thupi silingamve ma frequency otsika, zimapangitsa anthu kuganiza kuti kutsika kwa m'makutu sikukwanira.Popeza kamvekedwe ka m’makutu ka m’makutu n’kosiyana ndi kalankhulidwe ka m’makutu, zomvera m’makutu zili ndi njira yawoyawo yolumikizira mawuwo.Kuchulukirachulukira kwa zomvera m'makutu nthawi zambiri kumakhala bwino, zomwe zimapangitsa kuti anthu azimva bwino komanso kuti azimveka bwino;Chomverera m'makutu chokhala ndi mafupipafupi otsika kwambiri nthawi zambiri chimapangitsa anthu kumverera kuti ma frequency otsika ndi osakwanira ndipo mawu amakhala ochepa.Kukweza bwino mafupipafupi otsika ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito ndi mutu, zomwe zingapangitse kuti phokoso lamutu liwoneke bwino komanso kutsika kochepa kumakhala kozama.Zomvera m'makutu zopepuka ndi zotsekera m'makutu ndizo njira zomwe zimagwiritsidwa ntchito kwambiri.Ali ndi kagawo kakang'ono ka diaphragm ndipo sangathe kuberekanso ma frequency otsika kwambiri.Zokhutiritsa zotsika pafupipafupi zitha kupezeka pokonza ma frequency otsika apakati (80Hz-40Hz).Phokoso lenileni silikhala lokongola kwenikweni.Njira ziwirizi ndizothandiza pakupanga ma earphone, koma zambiri sizokwanira.Ngati ma frequency apamwamba komanso otsika asinthidwa mopitilira muyeso, kumveka bwino kwa mawu kumawonongeka, ndipo timbre yolimbikitsidwa imayambitsa kutopa mosavuta.Wapakatikati pafupipafupi ndi tcheru m'makutu m'makutu, kumene nyimbo zambiri zambiri, ndipo ndi malo tcheru kwambiri makutu a anthu.Mapangidwe a zomvera m'makutu amasamala za ma frequency apakatikati.Zomvera zam'makutu zotsika kwambiri zimakhala ndi ma frequency ocheperako, koma zimamveka zowoneka bwino komanso zakuthwa, zotumphukira komanso mawu amphamvu mwa kukonza magawo apamwamba ndi apansi a pafupipafupi, zomwe zimapangitsa chinyengo kuti ma frequency apamwamba ndi otsika ndi abwino.Kumvetsera zomvera m'makutu koteroko kwa nthawi yayitali kumakhala kotopetsa.

Phokoso labwino kwambiri la m'makutu liyenera kukhala ndi izi:

1. Phokosoli ndi loyera, lopanda "msisiti", "buzz" kapena "boo".

2. Kulinganiza ndikwabwino, timbre sichikhala chowala kwambiri kapena chakuda kwambiri, kugawa mphamvu kwa maulendo apamwamba, apakati ndi otsika ndi yunifolomu, ndipo kusakanikirana pakati pa maulendo afupipafupi ndi achilengedwe komanso osalala, popanda mwadzidzidzi ndi burr.

3. Kuwonjeza kwafupipafupi ndikwabwino, kosavuta komanso kosalala.

4. Kuthamanga kwafupipafupi kumakhala kozama, koyera komanso kodzaza, zotanuka komanso zamphamvu, popanda kumverera kwamafuta kapena pang'onopang'ono.

5. Kusokoneza pafupipafupi kwapakatikati kumakhala kochepa kwambiri, kowonekera komanso kofunda, ndipo mawuwo ndi okoma mtima komanso achilengedwe, okhuthala, maginito, osakokomeza phokoso la mano ndi m'mphuno.

6. Mphamvu zabwino zowunikira, tsatanetsatane wolemera, ndi zizindikiro zazing'ono zimatha kubwerezedwanso momveka bwino.

7. Kuthekera kofotokozera bwino kwamawu, malo omveka omveka, kuyika zida zolondola komanso zokhazikika, chidziwitso chokwanira m'munda wamawu, palibe kumverera kopanda pake.

8. Dynamic ilibe kupsinjika kowonekera, kumveka bwino kwa liwiro, palibe kupotoza kapena kupotoza pang'ono pa voliyumu yayikulu.

Mutu woterewu ukhoza kubwereza bwino mtundu uliwonse wa nyimbo, ndi kukhulupirika kwabwino ndi nyimbo.Kugwiritsa ntchito nthawi yayitali sikungayambitse kutopa, ndipo womvera akhoza kumizidwa mu nyimbo.
