Tam sim no feem ntau ntawm cov tuam txhab tsim xov tooj tam sim no hla 3.5mm lub mloog pob ntseg. Qhov no ua rau me ntsis nyuaj los txuas rau lub tsev kawm qub hais lus sab nraud uas xav tau kev pab tswv yim. Xijpeem koj yuav xav tau yuav lub adapter USB rau aux lossis tus txais bluetooth uas tuaj yeem txuas nrog cov hais lus no.

Kuv tau txais lub tso suab hais lus raws li khoom plig pub dawb thaum kuv tau yuav lub laptop tshiab. Nws tau siv los ntawm kev txuas mus rau txhua lub USB chaw nres nkoj uas tawm 5V 1amp thiab xav tau txuas nws lub suab pin rau lub suab tso.

Raws li qhov xav tau yog kev txhawj xeeb nws txwv rau wired ib, yog li kuv xav txuas ntxiv nws kom nws wireless nrog kev pab ntawm bluetooth lub mloog pob ntseg. Yog li ntawm no peb yuav hloov pauv tus hais lus tso suab tso rau bluetooth hais lus.

Kuv tab tom siv lub mloog pob ntseg bluetooth (uas yog kuv pom nws hauv kuv cov khoom khib nyiab:), tam sim no nws lub roj teeb tuag lawm).

Kuv xaiv lub mloog pob ntseg bluetooth no, vim ob leeg xav tau lub zog zoo ib yam 5V 1amp input (300mAh rau lub mloog pob ntseg). Yog li hauv qhov xwm txheej koj tsis muaj cov cuab yeej tshwj xeeb zoo ib yam; koj yuav xav tau siv lub zog sib txawv los yog siv qhov hluav taws xob yooj yim thiab tam sim no faib hluav taws xob rau lub zog hais lus thiab lub mloog pob ntseg bluetooth.

Kuj xyuas kom cov neeg hais lus tau tsim lub tshuab ua suab nrov li qhov tso tawm los ntawm bluetooth lub mloog pob ntseg yuav tsis tsav cov neeg hais lus. Koj tuaj yeem yuav cais chav kawm-D 2 channel amplifier los tsav cov hais lus.

Khoom siv

1. USB powered hais lus

2. Bluetooth lub mloog pob ntseg, yuav tsum yog lub tso suab.

3. (yeem) chav kawm D 2 channel amplifier.

4. (xaiv tau) USB lub zog siv raws li qhov tshwj xeeb ntawm tus hais lus thiab lub tshuab ua kom nrov nrov.

5. Plaub 1k - 10k resistors (txhua tus nqi zoo ib yam, rau kev sib txuas)

6. Lub rooj tsav xwm tsab ntawv (muab tso rau sab saum toj resistors)

7. Ob peb ntawm cov xov hlau

8. Soldering hlau thiab hlau

9. super kua nplaum

Kauj Ruam 1: Tshem Bluetooth Lub Pob Ntseg thiab Txheeb Xyuas Lub Hwj Chim thiab Suab Txuas

Tom qab disassembling bluetooth lub mloog pob ntseg, Kuv xam tawm nws lub zog tawm tswv yim thiab tso tawm suab txuas. Cov no yuav tsum yooj yim heev los txheeb xyuas ntawm lwm lub mloog pob ntseg bluetooth ib yam thiab; tsuas yog txheeb xyuas qhov twg lub roj teeb tau txuas nrog (uas yuav yog lub hwj chim nkag) thiab cov lus hais tawm qhov twg sab laug thiab sab xis hais lus txuas nrog.

Thov txheeb xyuas seb lub suab tso tawm muaj qhov sib npaug ntawm sab laug thiab sab xis, los ntawm kev ntsuas qhov tsis kam ntawm L+ thiab R+ LOS L- thiab R-. Yog tias kev tiv thaiv yog xoom ces nws ib txwm ua hauv paus. Koj tsis tas yuav ua raws cov theem hauv qab no.

Hauv kuv rooj plaub rau bluetooth lub mloog pob ntseg, ob sab xis thiab sab laug channel muaj cais av. Peb xav tau thaj chaw ib yam li USB tus hais lus lub suab tso tawm muaj qhov hauv paus. Txhawm rau ua ib qho av koj yuav tsum tau muab cov resistive lossis capacitive coupler nruab nrab ntawm sab laug thiab sab xis. (Koj tuaj yeem tshawb nrhiav txog nws).

Muaj qee qhov kev piav qhia nyuaj kom ua tiav nws, tab sis kuv pom qhov yooj yim tiv thaiv kev sib txuas ua kom nws ua haujlwm, thiab siv lub zog tawm tswv yim hauv av ib yam li hauv av. Tsuas yog tau txais plaub tus neeg muaj nuj nqis sib xws (nruab nrab ntawm 1k txog 10k) thiab txuas lawv rau txhua L+, L-, R+, R-. Thiab tom qab ntawd txuas cov resisters ntawm L+, L- ua ke kom tau txais cov suab tso tawm sab nraud thiab rov ua dua rau txoj cai tso suab.

Hauv qab no yog qhov txuas uas kuv tau hais txog StackExchange (ua tsaug rau StackExchange)

Siv diodes los sib xyaw 2 lub cim suab rau hauv ib pawg ntawm cov neeg hais lus (Ua tsaug rau GetFree thiab Majenko rau tshaj tawm lo lus nug thiab lus teb)

Kauj Ruam 2: Tshem Tawm Cov Neeg Hais Lus thiab Txheeb Xyuas Lub Hwj Chim thiab Suab Txuas

Tshem tawm ib qho ntawm tus neeg hais lus kom pom nws lub rooj tsav xwm hauv Circuit Court.

Yuav tsum muaj kev sib txuas ua rau nkag mus rau 5V DC los ntawm USB cable. Thiab yuav tsum muaj lub suab sib txuas ntawm nws uas yuav tsum txuas nrog rau 3.5 hli aux cable.

Kauj ruam 3: Ua Kev Sib Txuas

1. Txuas ob lub xov hlau ntawm lub rooj sib tham ntawm tus neeg hais lus qhov twg 5V cov tswv yim pub. Thiab txuas cov xov hlau no rau lub hwj chim rau lub mloog pob ntseg bluetooth. Xyuas kom koj tuav lub polarity.

2. Txuas lub resistive coupler rau L+, L-, R+, R- suab tawm pins rau bluetooth lub mloog pob ntseg. (Yog tias koj lub mloog pob ntseg bluetooth muaj qhov hauv ib puag ncig, tseem kuv xav hais kom tso qee qhov kev tiv thaiv nruab nrab ntawm 1k- 5k rau L thiab R tso tawm raws li nws yuav tsum tau muab tso tawm los ntawm pawg thawj coj saib bluetooth, thiab nws yuav kib tawm cov khoom ntawm cov neeg hais lus suab)

3. Txuas cov couplers tso tawm (L thiab R) rau L thiab R ntawm cov neeg hais lus hauv Circuit Court.

4. Txuas lub hwj chim tawm tswv yim (-ve) lub dav hlau ua lub hauv paus rau cov suab tawm tswv yim. (Nws yuav muab qee qhov hnov suab dawb thaum lub qhov DC nkag mus muaj qee lub suab nrov. Kuv tseem tsis tau txiav txim siab qhov kev daws teeb meem rau nws.

5. Tam sim no tshuaj xyuas txhua qhov kev sib txuas nrog multimeter siv nws qhov kev ntsuas luv luv txhawm rau txheeb xyuas seb koj puas tau ua yam tsis xav tau luv luv txuas txuas:)

6. Muab tus neeg hais lus rov qab npog thiab txuas lub mloog pob ntseg bluetooth, Kuv tau khaws nws sab nraud kom kuv tuaj yeem siv nws cov kev tswj hwm. Nws kuj tseem muaj mic yog li kuv tuaj yeem siv nws rau kev hu ib yam nkaus.

7. Hwj chim nws ON thiab ua ke nrog xov tooj !! Txaus siab rau cov hais lus wireless bluetooth!
