Taw qhia
Koj puas tau pom tias lub koob yees duab smartphone tam sim ntawd tsom mus rau qhov khoom nyob ze thiab tom qab ntawd ntawm qhov deb yam tsis muaj suab nrov? Qhov ntawd du, ntsiag to tsom yog siv los ntawm VCM (Voice Coil Motor) actuator. VCM autofocus lub koob yees duab module siv electromagnetic quab yuam txav lub lens meej, ua tiav ceev thiab ntsiag to tsom. Cov tshuab no tsis yog rau cov xov tooj xwb; nws kuj tseem siv rau hauv cov khoom siv kho mob, kev tshuaj xyuas kev lag luam, thiab kev pom kev pom. Ntawm Sincere, peb tau raug tsimcmos module koob yees duabkev daws teeb meem rau ntau tshaj 30 xyoo, suav nrogautofocus lub koob yees duab moduletsim nrog VCM. Kab lus no piav qhia tias VCM autofocus lub koob yees duab module yog dab tsi, nws ua haujlwm li cas, thiab nws siv qhov twg.
VCM Autofocus yog dab tsi?
VCM stands rau Lub Suab Coil Tsav. Nws yog ib qho electromagnetic actuator uas txav lub lens raws qhov kho qhov muag axis los hloov ua kom pom tseeb. Nyob rau hauv lub koob yees duab module, lub kauj txuas nrog lub lens tuav cuam tshuam nrog cov hlau nplaum ruaj khov. Thaum tam sim no ntws los ntawm lub kauj, lub lens txav. Los ntawm kev tswj cov tam sim no, lub lens tuaj yeem muab tso rau hauv qhov tseeb ntawm qhov raug tsom mus deb.
A VCM autofocus usb koob yees duab moduleintegrates cov txheej txheem no rau hauv USB-txuas lub koob yees duab, muab plug-and-play autofocus rau computers thiab embedded systems.
