Txog 80% ntawm cov khoom siv hluav taws xob raug puas tsuaj feem ntau yog los ntawm kev sib tsoo. R& D cov neeg ua haujlwm feem ntau siv ntau lub sijhawm thiab raug nqi los ua cov kev ntsuas kom zoo rau cov khoom. Cov kev ntsuas sib txawv tshaj plaws yog kev xeem poob.
Qhov kev xeem poob feem ntau yog siv los sim lub caij nplooj zeeg dawb uas cov khoom yuav raug rau lub sijhawm tuav, thiab tshawb xyuas lub peev xwm ntawm cov khoom kom tiv qhov poob siab poob nthav. Kev ntsuam xyuas poob yog ib qho ntawm cov kev ntsuam xyuas kev cia siab uas cov khoom siv hluav taws xob feem ntau ua ntej lawv tawm hauv lub Hoobkas. Cov kev ntsuam xyuas qhov chaw thau ntim suav nrog kev ntsuam xyuas pob thiab kuaj cov hlau tsis pom qhov kev ntsuam xyuas, kom nkag siab qhov khoom puas tsuaj thiab ntsuas qhov qis thiab qhov siab ntawm cov khoom ntim ntim thaum lawv poob. Cuam tshuam lub zog, txhawm rau tshawb xyuas qhov muaj peev xwm ntawm cov khoom kom tiv thaiv qhov tsis muaj kev cia siab.
Qhov kev ntsuas tus qauv yog poob saum npoo, cov naj npawb ntawm cov tee, poob qhov siab, thiab cov kev taw qhia poob.
Feem ntau qhov poob qhov siab feem ntau yog ua raws qhov hnyav ntawm qhov khoom thiab qhov tshwm sim ntawm qhov poob qis raws li kev siv tus qauv. Rau cov txheej txheem thoob ntiaj teb sib txawv, txawm tias cov khoom hauv qab yuav hnyav tib yam, qhov siab poob qis yuav txawv. Rau cov khoom siv tes ua (xws li xov tooj ntawm tes, MP3, thiab lwm yam), feem ntau ntawm txoj kev tso cia qis yog siab li 100cm ~ 150cm.
Qhov poob saum npoo yuav tsum du, khov thiab ua kom cov npoo ua cov pob zeb ua los yog steel (yog tias muaj cov cai tshwj xeeb, nws yuav tsum tau txiav txim siab los ntawm cov khoom lag luam lossis cov neeg siv kuaj cov khoom tshwj xeeb).
Tom qab dhau qhov kev xeem dhau los, cov khoom tsim thiab ntim ntim tuaj yeem txhim kho kom zoo dua qub thiab zoo meej raws li qhov xwm txheej tiag tiag ntawm cov khoom lag luam thiab cov kev txwv ntawm cov qauv teb chaws.
