Wb txiav mus caum. Thaum koj hloov tus neeg hais lus tsav tsheb rau cov rooj sib tham, koj qhov kev ntshai loj tshaj plaws yog dab tsi? Kev xa khoom qeeb? Lub suab tsis zoo? Los yog tsis tuaj yeem ncav cuag leej twg thaum muaj teeb meem?
Honestly, kuv twb pom tag nrho peb. Thiab 90% ntawm cov neeg yuav khoom ntaus tsawg kawg yog ib qho ntawm cov no thaum hloov cov neeg muag khoom thawj zaug.
Kuv paub li cas? Vim tias XDEC (Shenzhen Xuanda Electronics Co., Ltd.) tau nyob hauv kev lag luam electroacoustic rau 17 xyoo, ua haujlwm rau ntau lub rooj sib tham zaub hom. Peb tau pom ntau yam teeb meem thaum lub sijhawm hloov pauv tus neeg siv khoom. Kab lus no tsis yog hais txog tus hais lus tsis sib xws- nws yog hais txog yuav ua li cas txheeb xyuas cov neeg muag khoom uas ntseeg tau thiab qhov twg tsis yog.
1. Lub 3 Feem ntau Pitfalls Thaum Hloov Cov Chaw Muag Khoom
Cia peb pib nrog cov pitfalls. Saib seb puas phim koj qhov kev paub.
Pitfall 1: Kev xa khoom qeeb uas nco koj lub qhov rais tso tawm khoom
Cov rooj sablaj nthuav qhia muaj cov phiaj xwm nruj. Nco lub sijhawm kawg ntawm kev sib tw, thiab koj nco ib xyoo tag nrho. Ntau tus neeg yuav khoom tshawb pom thaum lawv thawj tus neeg xa khoom hloov pauv uas lub Hoobkas hais tias "30 hnub xa khoom" tab sis xaus rau 45 hnub vim tias tus neeg muag khoom tshiab xav tau sijhawm los ua kom zoo - kho lawv cov pwm. Cov khoom xa tawm qeeb, hom hloov mus rau lwm tus neeg muag khoom.
Pitfall 2: Lub suab tsis zoo ua rau cov neeg siv khoom tsis txaus siab
Cov lus qhia hauv lub rooj sab laj yuav tsum muaj qhov tseeb, suab nrov - lub suab dawb - cov thawj coj hais lus thiab kev hu xov tooj yuav tsum yog nkig. Thawj batch qauv zoo, tab sis tom qab ntau lawm koj pom txhua batch suab txawv. Qee cov batch yog muffled, lwm tus muaj static. Cov neeg siv khoom tsis txaus siab nce siab, cov khoom lag luam tuav lub luag haujlwm.
Pitfall 3: Tsis tuaj yeem ncav cuag leej twg thaum muaj teeb meem tshwm sim, lossis lawv dhau qhov nyiaj
Tom qab hloov chaw muag khoom, koj ntsib teeb meem hais lus. Lub Hoobkas hais tias "koj siv nws tsis raug," "koj tus qauv tsim muaj teeb meem," "koj cov txheej txheem yog qhov teeb meem." Koj raug ntes nyob rau hauv nruab nrab, daig ntawm lub Hoobkas thiab hom. Qhov no yog qhov tshwj xeeb tshaj yog nrog cov chaw tsim khoom me me-lawv tau koom tes ua ntej muag, tab sis yuav khiav tawm thaum muaj teeb meem.
2. 5 Cov Qauv rau Kev Txiav Txim Lub Rooj Sab Laj Saib Cov Neeg Hais Lus Tsav Tsheb
Tam sim no koj paub qhov pitfalls. Nov yog yuav ua li cas kom zam tau lawv. 5 cov qauv no yog ua raws li 17 xyoo ntawm kev paub- ua raws li lawv, thiab koj yuav txo koj txoj kev pheej hmoo ntawm kev tsoo cov pitfalls los ntawm 80%.
| Txuj | Txais tau | Zoo heev | Tus chij liab |
|---|---|---|---|
| Qauv teb ceev | 3-5 hnub ua haujlwm | Hauv 48 teev | Tshaj li 7 hnub txhais tau hais tias lub Hoobkas yog overloaded |
| Parameter sib xws kev cog lus | Hais lus "peb lav qhov sib xws" | Muab cov ntaub ntawv soj ntsuam tag nrho + cov ntaub ntawv | Kev tsis kam muab cov ntaub ntawv yog qhov tsis txaus ntseeg |
| Delivery warranty cov nqe lus | Lo lus "tsis muaj teeb meem" | Daim ntawv cog lus qhia txog kev xa khoom + nplua nqe lus | Nug txog MOQ rau kev txiav txim mus sib hais |
| Teeb meem teb ceev | 2-3 hnub los teb | Teb hauv 2 teev | Factories uas deflect teeb meem yuav tsum tau zam |
| Yooj yim | Tsuas yog muab cov khoom txheem | Txaus siab rau customize parameter | Nug "koj puas tuaj yeem kho impedance / hwj chim?" |
💡 Cov lus qhia ua tau zoo:Rau koj thawj qhov kev txiav txim, tsis txhob tso qhov kev txiav txim loj ncaj qha. Pib nrog cov khoom me me (100-200 khub) txhawm rau kuaj cov khoom xa tuaj ruaj khov, suab zoo sib xws, thiab cov teeb meem teb ceev. Tsuas yog nce ntim tom qab dhau peb qhov kev xeem no.
3. Cov ntsiab lus xaiv tseem ceeb rau 30 × 20mm Conference Display Speaker Drivers (Technical Supplement)
Tshooj saum toj no suav nrog kev ntsuam xyuas tus neeg muag khoom. Yog tias koj xav nkag siab txog thev naus laus zis koj tus kheej, ntawm no yog cov ntsiab lus tseem ceeb xaiv.
Rau lub rooj sib tham cov lus, lub mainstream laptop hais lus tsav tsheb loj yog 30 × 20mm, kwv yees li 5 hli nyob rau hauv qhov siab. Cov neeg hais lus hauv qhov loj no feem ntau muaj 1-2W lub zog thiab 4Ω lossis 8Ω impedance.
Yuav xaiv lub hwj chim li cas?
Cov rooj sib tham muaj qhov txwv tsis pub muaj qhov chaw, yog li zam qhov siab - tsav tsheb fais fab . 1-2W yog qhov kev xaiv tseem ceeb- txaus rau feem ntau cov kev xav tau. Yog tias cov kab noj hniav loj dua me ntsis, 2W muab ntim zoo dua.
Yuav ua li cas xaiv impedance?
4Ω muaj zog tsav ntau dua tab sis muaj zog siv zog ntau dua, haum rau cov kab noj hniav me me uas yuav tsum tau ntim siab . 8Ω muaj ntau yam thiab sib xws nrog cov khoom siv hluav taws xob feem ntau ICs. Yog tias koj siv tus qauv siv tus qauv tsim los ntawm 方案商 (lub chaw muab kev daws teeb meem), 8Ω feem ntau yog tsim nyog.
Yuav ua li cas yog rhiab heev?
Cov xwm txheej hauv lub rooj sib tham yuav tsum muaj lub suab meej meej, yog li kev nkag siab yuav tsum siab dua lossis sib npaug li 90dB. Cov neeg hais lus tsav tsheb nrog qis rhiab heev yuav tsim suab nrov, ua rau nws nyuaj rau hnov thaum lub rooj sib tham.
4. FAQ
Q1: Kuv puas yuav tsum siv 4Ω lossis 8Ω rau lub rooj sib tham zaub hais lus tsav tsheb?
A: Nws nyob ntawm koj tus qauv amplifier. 4Ω muaj zog tsav tsheb ntau dua tab sis siv lub zog ntau dua, haum rau cov kab noj hniav me me uas xav tau ntim siab. 8Ω muaj ntau yam thiab sib xws nrog cov neeg muab kev daws teeb meem feem ntau cov qauv amplifier ICs. Yog tias tsis paub meej, ua qhov tseem ceeb 8Ω.
Q2: Kuv yuav tsum tau xaj ntau npaum li cas rau thawj qhov kev sim nrog tus neeg xa khoom tshiab?
A: 100-200 khub raug pom zoo. Lub hom phiaj ntawm kev txiav txim mus sib hais tsis yog kom txuag tau nyiaj-nws yog los ntsuas lub Hoobkas kev xa khoom ruaj ntseg, suab zoo sib xws, thiab cov teeb meem teb ceev. Tsuas yog nce ntim tom qab dhau peb qhov kev xeem no.
Q3: Lub Hoobkas cog lus 30-hnub xa khoom. Lawv puas yuav ncua sijhawm?
A: Nws nyob ntawm lub Hoobkas qhov ntsuas. Cov chaw tsim khoom me me yooj yim ncua thaum lawv muaj ntau yam xaj. Cov chaw tsim khoom loj muaj lub sijhawm ruaj khov dua. Nug lawv: "Puas muaj pes tsawg daim ntawv xaj tam sim no koj ua haujlwm?" Yog tias lawv cov lus teb tsis meej, tej zaum yuav muaj teeb meem.
Q4: Kuv yuav ua li cas kom lub suab zoo sib xws thaum lub sijhawm tsim khoom ntau?
A: Xav kom lub Hoobkas muab cov ntaub ntawv soj ntsuam tag nrho. Tshawb xyuas qhov tseem ceeb tsis xws li rhiab heev thiab F0 rau txhua pawg. Cov ntaub ntawv xa khoom yuav tsum muaj cov ntaub ntawv. Yog tias lub Hoobkas tsis kam muab cov ntaub ntawv, lawv qhov zoo yuav tsis ruaj khov, lossis lawv muaj qee yam zais.
Q5: Yuav ua li cas yog lub Hoobkas deflects thaum muaj teeb meem tshwm sim?
A: Kev tiv thaiv ua ntej qhov tseeb yog qhov zoo dua li kev lav phib xaub tom qab. Sau cov ntsiab lus meej rau hauv cov ntawv cog lus: kev xa khoom ncua sij hawm raug nplua, cov teeb meem zoo rov qab / pauv txoj cai, thiab cov teeb meem teb lub sij hawm cog lus. Ua ntej kos npe, nug kom meej: "Koj yuav daws teeb meem li cas thaum lawv tshwm sim?" Saib seb lawv cov lus teb yog ncaj nraim los yog evasive.
