Kucace gca ukuba yintoni umahluko phakathi kwesikrini esigcweleyo se-HD kunye nesikrini se-HD, naphakathi kwekhamera ye-13 kunye nekhamera ye-megapixel engama-20, kodwa akucaci ukuba yintoni umahluko ngokubhekiselele kwimveliso yesandi, kuba kutheni lo mahluko. . Esinye sezitshixo yiDAC ephathwayo.
Yintoni iDAC?
Ii-headphones, okanye izithethi, zifuna isignali ye-analog. Nangona kunjalo, iimobiles zinenkqubo yedijithali. Ngoko ke, kuyimfuneko ukuguqula isignali ukusuka kwidijithali ukuya kwi-analog. Ngelixa isignali yedijithali yenziwe ngamaxabiso amabini, u-1 kunye no-0, isignali ye-analog yenziwe zii-electromagnetic pulses. Indlela yokuhamba ukusuka kwisignali yohlobo lokuqala ukuya kwisignali yodidi lwesibini? Nge-DAC, emele "I-Digital-to-Analog Converter," okanye ukuguqulwa kwedijithali ukuya kwi-analog.
Umgangatho weDAC?
Zonke ii-mobiles kunye neekhompyuter ezine-jack socket zine-DAC eyakhelweyo. Iselula yakho nayo ineDAC. Nangona kunjalo, kukho iiDAC zomgangatho olungileyo kunye neeDAC eziqhelekileyo. Zeziphi iimobiles ezinomgangatho weDAC? Ngokubanzi, iimobiles ezikumgangatho ophezulu zinee-DAC ezisemgangathweni, nangona oku kusenokungabi njalo kuzo zonke iiselfowuni. Umzekelo, i-iPhone 6s Plus ayinayo i-Hi-Res ehambelana ne-DAC, ngelixa i-Samsung Galaxy ephezulu yenza. Ezinye ii-mobiles ezinee-DAC ezikumgangatho ophezulu yi-Meizu Pro, zombini i-Meizu MX4 Pro kunye ne-Meizu Pro 5 entsha, ngokuchanekileyo kuba i-Meizu yayinezixhobo zesandi ezikumgangatho ophezulu.
Isandi esingcono?
Ngoku, ngaba ezi ziselfowuni, njengezo sele zikhankanyiwe, zinesandi esingcono ngokwenene? Ewe kwaye hayi. Izithethi zakho azivakali ngcono. Kungenzeka ukuba isithethi se-Meizu Pro 5 sibi kakhulu kune-iPhone 6s Plus, umzekelo. Kodwa eyona nto ibalulekileyo ye-DAC kuxa sisebenzisa isixhobo sesandisi-lizwi apho sithumela khona umqondiso osuka kwiDAC. Xa sisebenzisa i-headphones, okanye xa sidibanisa izithethi, umgangatho ozwakalayo we-Meizu Pro 5 uya kuba ngcono kune-iPhone 6s Plus. Ke, i-DAC yenye yezona zinto zibalulekileyo xa sijonga umgangatho wesandi se-smartphone yethu ngekhompyuter okanye ngee-headphones.
