Lub lim tiam dhau los, thaum lub sijhawm tshuaj xyuas cov khoom lag luam rau cov khw muag khoom yooj yim nyob rau sab hnub tuaj Asia, tus thawj coj ntawm kev yuav khoom tau nug peb: "Koj tau hais lus rau 17 xyoo-koj MOQ yog dab tsi? Koj tuaj yeem xa daim ntawv xaj sai npaum li cas?" Peb hnov ​​lo lus nug no txhua lub lim tiam. XDEC (Shenzhen Xuanda Electronics) tau tsim muaj nyob rau hauv 2009, nrog 17 xyoo ntawm kev cog lus hais lus tsim, nyob hauv Shenzhen, Suav. Peb tuav tsib daim ntawv pov thawj: ISO9001: 2015, ISO14001: 2015, IATF16949, TUV Rheinland, thiab Shenzhen High-Tech Enterprise.
Kev sim MOQ: 500pcs. Standard MOQ: 3,000 daim. Customized MOQ: 10,000 daim. Cov khoom txheem xa tawm los ntawm cov khoom muag hauv 3-5 hnub. Cov qauv kev cai siv sijhawm 15-20 hnub. Cov lus xaiv xaiv tus neeg hais lus xa tuaj hauv 24 teev; spec daim ntawv tshuaj xyuas hauv 48 teev.Cov no yog cov lej nyuaj POS cov npe lag luam nug thaum lub sijhawm kev tshuaj xyuas tus neeg muag khoom.

POS systems xav tau ntawm beep tones. Nws tsis yog "beep thiab mus" - tus neeg hais lus yuav tsum nyob twj ywm tom qab ntau pua txhiab tus xovxwm tseem ceeb. Φ26-Φ30mm mylar speaker dominate qhov luaj li cas. Tab sis nrog cov ntawv tshwj xeeb zoo ib yam (Φ28mm, 8Ω, 1W, 88dB rhiab heev, F0 280± 20% Hz), peb lub Hoobkas tuaj yeem tsim cov khoom nrog 5x sib txawv teb rov qab tus nqi tom qab 2 xyoos. Peb tau pom ntau tus tswv lag luam hloov 2-3 tus neeg muag khoom ua ntej paub tias: xaiv qhov tsis ncaj ncees lawm Φ28mm tus neeg hais lus tsis yog $ 0.30 chav tsev nqi teeb meem-nws yog cov tshuaj tiv thaiv ntawm cov neeg siv khoom tsis txaus siab, rov qab los, thiab lub npe nrov npe puas tsuaj.

Xyoo tas los peb tau pab South Tuam Tshoj POS hom hloov chaw muag khoom. Tus thawj Φ28mm mylar speaker tsum tsis muaj teeb meem rau 2 xyoos, tab sis tom qab lub hom tau tsiv ntau lawm mus rau ib tug South Asia daim ntawv cog lus chaw tsim tshuaj paus, tag nrho cov batch pom 18% rhiab heev kam rau ua drift-lub ntsiab lus ± 3dB. Ob lub POS terminals nrog tib cov specs yuav muaj ib qho nrog "beep" thiab lwm qhov nrog muffled "beep." Qhov no tsis yog kaum -txiav- nws yog qhov tsis muaj cov qauv ntsuas nruj thiab cov txheej txheem tsis ruaj khov.

Tom qab peb mus rau hauv nrog 17 xyoo ntawm± 1.5dB sib phim -pair grading (ntawm IQC theem)thiab rebuilt peb ntau lawm batch, lub teb rov qab tus nqi poob los ntawm 12% mus rau 2% nyob rau hauv 2 xyoo. Qhov kev ruaj ntseg no tau raug txheeb xyuas los ntawm 8+ lab units xa mus rau cov kab kev lag luam tshaj tawm. Cov tswv lag luam yuav tsum saib xyuas dab tsi tsis yog "txawm tias daim ntawv qhia tshwj xeeb sib tw"- nws yog "txawm tias cov neeg siv khoom tsis txaus siab yuav muab ob npaug rau 2 xyoos txij li tam sim no."
