Taw qhia
Cia kuv pib nrog keeb kwm yav dhau me ntsis. Yog li dab tsi yog lub nraub qaum hais lus horn? Xav txog nws li lub xov tooj cua rov qab los yog gramophone. Lub xov tooj cua (ib puag ncig lub suab nrov nrov pem hauv ntej) siv lub suab nrov nrov los ua kom muaj txiaj ntsig tag nrho ntawm kev tsav tsheb (piv txwv li lub suab tawm los ntawm sab xub ntiag). Ib lub nraub qaum hais lus ua suab zoo ib yam nkaus. Txawm li cas los xij, ntawm no lub suab nrov tau txuas rau sab nraum qab ntawm tus hais lus. Yog li koj tau txais qhov tso tawm ncaj qha los ntawm lub hauv ntej ntawm tus tsav tsheb PLUS ib qho los ntawm lub suab raj tom qab. Cov zaus uas tau nthuav dav thiab zoo npaum li cas nyob ntawm chav cua, caj pas (ntu nqaim), thiab ntawm qhov ntev, tsim qauv, thiab txoj kab uas hla ntawm lub raj. Tshwj xeeb nrog cov tsav tsheb me (thiab pheej yig) qhov no tuaj yeem txhim kho lub suab zoo.
Kuv yuav hu lub tswv yim no "hnia tus qav". Koj coj tus tweeter me me thiab vam tias nws hloov mus ua tus tub huabtais. Thiab yog, nws yeej ua tau. Nws yog qhov txaus siab npaum li cas lub suab koj tuaj yeem tawm ntawm $ 10 3.3 "tus neeg tsav tsheb.
Koj yuav pom ntau cov phau ntawv, ntawv, thiab cov ntawv xa hauv online rau yuav ua li cas thiaj tsim lub suab hais lus zoo. Qhov teeb meem yog tias koj xam pom qhov zoo tshaj yuav zoo li yuav noj ntau ntawm koj chav nyob. Txawm li cas los xij, Kuv pom cov cuab yeej no pab tau zoo kom nkag siab zoo dua qub (piv txwv li muaj dab tsi tshwm sim thaum kuv hloov lub taub, ntev, tsim lub suab raj?). Thaum kawg, tus tsim ntawm (rov qab) lub suab hais lus (twv yuav raug hu 3D luam tawm ib qho) feem ntau yuav raug coj los ntawm qhov chaw muaj thaum sim ua kom muaj suab ntau npaum li tawm ntawm lub thawv me me / tus tsav tsheb.
Rau qhov kev tsim no koj yuav tsum tau nkag mus rau lub tshuab luam ntawv 3D. Kuv tab tom siv $ 200 Creality Ender 3 3D tshuab luam ntawv, uas tuaj yeem luam tawm txog 220x220x250 mm (thiab ua haujlwm zoo ntawm qhov ntawd). Lub cev tau tsim kom haum rau tus qauv 200x200 mm tsim phaj, yog li feem ntau (txawm tias pob nyiaj siv) cov tshuab luam ntawv yuav tsum muaj peev xwm luam tau qhov no. Yog tias koj xav siv nws los ua tus hais lus Bluetooth koj yuav xav tau cov txuj ci hluav taws xob yooj yim thiab cov khoom siv dag zog. Nco ntsoov tias koj paub tias koj tab tom ua dab tsi (tshwj xeeb yog cuam tshuam nrog qhov hluav taws xob siab! Yog li saib xyuas, txhua yam ntawm koj tus kheej txoj kev pheej hmoo thiab tsis muaj kev lees paub dab tsi). Txawm li cas los xij, nco ntsoov, koj ib txwm tuaj yeem siv lub thawv ntawv ua tus hais lus tsis zoo, uas tsis suav tag nrho cov laug.
Kauj Ruam 1: Cov Khoom Siv Hluav Taws Xob
Yeej qhov no yog qhov project pheej yig heev. Txhua yam khoom siv hluav taws xob koj xav tau rau Bluetooth version yuav tsum raug nqi ib ncig $ 20.
- Ua ntej tshaj plaws koj yuav xav tau MP3 Bluetooth Decoder Board (kwv yees li $ 1). Koj tuaj yeem siv txoj kev xav siv lub tshuab hluav taws xob nrog BT ua ke. Qhov teeb meem yog txoj hauv kev no koj yuav zam tsis dhau nrog lub tso suab hais lus teeb liab - zoo yog tias koj xav txuas 2 tus neeg hais lus (tus hais lus thib ob txuas nrog thawj zaug los ntawm xaim), tsis zoo yog tias koj xav tau ib leeg (mono) hais lus zoo li koj tsis tuaj yeem suav cov teeb liab tawm los ntawm ob qho kev sib txuas. Cov pawg BT cais cais tso cai rau ua ke cov kab tawm teeb liab ua ntej pub mis rau hauv lub tshuab raj.
- Lub suab nrov yog TPA3116 D2 Dual Channel 50Wx2 Amplifier Module (kwv yees. yuav tuaj yeem siv tau yog tias koj xav txuas 2 tus hais lus). Rau mono koj yuav xav tau tus choj L thiab R raws los ntawm BT pawg thawj coj (saib ntu txuas kab).
- Zoo nkauj npaum li 12V/1A+ (ntau dua qhov zoo dua) cov khoom siv hluav taws xob (kwv yees li $ 1.7) yuav ua. Piv txwv li lub qub 12V laptop lub zog hloov pauv yuav zoo. Kuv siv qhov me me 10x15 mm rocker hloov ua lub zog hloov pauv (uas yog nyob ntawm yeem raws li lub tshuab raj muaj qhov hloov pauv hloov mus rau hauv kev tswj ntim - uas, txawm li cas los xij tsuas yog hloov lub suab nrov).
- Me me LM1117 Kauj Ruam Down hloov pauv (kwv yees $ 0.2). Qhov no yuav hloov 12V los ntawm lub zog hloov mus rau 5V xav tau rau BT pawg thawj coj.
- Tus tsav tsheb uas kuv siv yog Visaton FRS 8 M - 8 Ohm 8 cm (3.3 ) tus neeg hais lus puv ntoob (ncig $ 10).
Txawm li cas los xij, ib qho kev sib xyaw ua ke yuav ua (tsuav tus neeg tsav tsheb yog 3.3 "lossis me dua yog li nws haum rau lub thawv ntawv - yog tias koj siv tus tsav tsheb sib txawv koj yuav tsum tau hloov kho me ntsis lub qhov mounting). Kuv tau ua tus adapter rau 2.5" tsav tsheb tab sis yuav pom zoo tiag kom siv tus loj dua 3 lossis 3.3 "tus tsav tsheb.
Kauj Ruam 2: Luam Ntawv 3D
Cov ntaub ntawv nws tus kheej yog 100% luam tawm. Tag nrho.stls tau txuas nrog. Txhua yam koj xav tau yog ob peb M3 ntsia hlau txhawm rau txhim kho tus tsav tsheb, lub phaj rov qab, thiab ko taw ntxiv rau qee cov kua nplaum los txuas rau sab nrauv. Rau sab panels koj muaj ob txoj kev xaiv. Tog twg los luam ntawv lossis txiav lawv los ntawm 6-8 hli (ply) ntoo. Kuv tau suav nrog 1: 2 txoj kev npaj (.pdf) rau kev txiav cov ntawv sab (thiab tau kawg.stls rau luam ntawv). Yeej lawv yooj yim 20 x 15 cm laug cam nrog 10 mm fillets ntawm 3 lub ces kaum thiab 3 mm fillet ntawm 4.
Kev luam ntawv nws tus kheej yuav tsum yooj yim zoo nkauj. Koj yuav pom tias lub cev muaj npog 1 hli ntawm ib sab. Qhov no yog ua kom nws ruaj khov dua thiab ua kom yooj yim dua rau luam tawm thiab tshem tawm ntawm lub tshuab luam ntawv. Tsis xav tau kev txhawb nqa lossis txuas ntxiv.
Hlais hauv koj cov software uas koj nyiam tshaj (Kuv siv Cura). Luam tawm hauv PLA (lossis ABS, PETG… dab tsi uas koj nyiam tshaj plaws yog) ntawm 0.28 mm daws teeb meem thiab (ib puag ncig) 15% ntxiv. Koj yuav muab cov nplaum lo rau ntawm lub cev (tom qab teeb tsa tus tsav tsheb thiab cov khoom siv hluav taws xob) thiab lub hauv ntej thiab tus neeg hais lus yuav txuas nrog M3 cov ntsia hlau thiab lub vaj huam sib luag tom qab uas npog cov khoom siv hluav taws xob ib yam. Taw (Kuv luam cov no hauv TPU) yog nyob ntawm yeem.
Pib los ntawm kev luam ntawv
- lub cev (1 daim). Lub cev yog ib qho luam tawm, hauv nws tus kheej xav tau tsis muaj cov ntsia hlau los yog gluing, muaj 1 hli npog ntau dua ntawm sab qis (uas ntau ntxiv rau kev ruaj ntseg), ntawm 15% infill siv li 350 g ntawm cov ntsiab lus, thiab siv ib puag ncig 20 teev los luam tawm. Hais lus_Body_V2.stl
- ua raws los ntawm cov vaj huam sib luag sab (yog tias koj tsis txiav lawv los ntawm ntoo - luam 1 daim ib qho, sab xis thiab sab laug, feem) Speaker_Side_002_PartA.stl THIAB Speaker_Side_002_PartB.stl LOSSIS Speaker_Side_Pannels_Drawing.pdf
- lub npog me me rau cov khoom siv hluav taws xob (1 daim), uas muaj qhov qhib rau kev tswj ntim, qhov hloov pauv rocker, thiab 12 V fais fab cable. Hais lus_Back_V2.stl

- xaiv tau: ntim pob qhov rooj (1 daim), uas yooj yim swb hla lub ntim tswj ntawm lub tshuab raj - Speaker_Knob_V2.stl
Kauj Ruam 3: Kev thaiv kab hlau
Yog tias koj tab tom mus rau qhov kev xaiv Bluetooth koj yuav xav tau cov txuj ci hluav taws xob yooj yim thiab cov khoom siv dag zog. Txawm li cas los xij, ib txwm muaj qhov kev xaiv siv lawv ua tus hais lus tsis zoo (piv txwv li koj tsuas yog txuas tus tsav tsheb nrog cov khoom siv los ntawm lub tshuab hluav taws xob sab nraud).
Nco ntsoov xaim thiab ntsuas tag nrho koj cov khoom siv hluav taws xob ua ntej muab tso rau hauv lub thawv ntawv (tshwj tsis yog 12V lub zog txuas hluav taws xob thiab hloov rocker, uas dhau los ntawm lub qhov hauv qab npog), qhov no ua rau daws teeb meem tau yooj yim dua.
Nov yog rau cov npe khoom siv saum toj no thiab tej zaum yuav txawv yog tias koj siv cov khoom sib txawv. Txuas qhov tso tawm los ntawm 12V lub zog hloov hluav taws xob (qhov no mus los ntawm lub qhov me me hauv lub vaj huam sib luag tom qab!) Mus rau POWER IN (cim VCC thiab GND) ntawm lub rooj tsav xwm hais lus PLUS rau me ntsis LM1117 board (VIN thiab GND) - 5V tso tawm (VOUT thiab GND) los ntawm LM1117 pawg thawj coj tau txuas nrog lub zog hauv ntawm pawg thawj coj saib BT. Yog (zoo li kuv ua) koj siv qhov no los ua tus mloog MONO nkaus xwb, txuas L thiab R tawm los ntawm BT pawg thawj coj (qhov no yog tseem ceeb, nws yuav muab lub teeb liab mono rau koj, tsis txhob siv ib nrab tso suab!). Tam sim no koj txuas tus txuas L/R thiab GND los ntawm BT pawg thawj coj rau kab hauv (IN-L LOS YOG IN-R thiab GND) ntawm lub tshuab raj (yog tias koj siv lub tso suab tso suab, txuas mus rau sab laug LOS YOG txoj cai channel). Thaum kawg txuas cov zis los ntawm lub tshuab raj (L+ thiab L- LOS R+ thiab R-) mus rau+ thiab- ntawm tus hais lus.
Rocker hloov yog xaiv tau (rau 12V lub zog). Txawm li cas los xij, muaj qhov qhib nyob rau sab nraub qaum, yog li nws yooj yim rau mount (tab sis yuav tsum tau muab tso rau hauv lub nraub qaum ua ntej yuav laug).
Sim txhua qhov no ua ntej txhawm rau txhim kho txhua yam hauv lub thawv ntawv (qhov no yeej pab daws teeb meem).
Kauj ruam 4: Sib dhos
Tam sim no koj yuav tsum muaj tag nrho cov ntawv luam tawm thiab cov xaim (thiab kuaj) cov khoom siv hluav taws xob npaj rau kev sib sau ua ke. Tsuas yog lub rocker hloov thiab lub zog txuas hluav taws xob yuav tsum tau nyob hauv qhov chaw ua ntej yuav siv tau.
- Mount tus neeg hais lus ntiv nplhaib rau sab nraud thiab tus tsav tsheb mus rau sab hauv ntawm lub thaiv nrog plaub M3 ntsia hlau (12 hli) thiab txiv ntseej. Ntxig rau kab hauv kab me me nyob rau sab nraum qab ntawm chav hais lus.
- Mount lub suab nrov rau sab nraub qaum (uas muaj lub qhov rau tswj lub ntim) - txiv ntoo ntawm lub ntim tswj yuav tuav nws hauv qhov chaw.
- Mount lub Bluetooth board sab hauv lub tshuab hluav taws xob (siv cov kua nplaum me me kom ntseeg tau tias nws nyob hauv qhov chaw)
- Mount lub nraub qaum nrog ob lub M3 ntsia hlau.
- Kaw ob sab vaj huam sib luag rau lub cev tseem ceeb. Tej zaum koj yuav xav tau xuab zeb qhov chaw sib cuag nrog cov ntawv xuab zeb ua ntej gluing.
- Txuas ko taw nrog cov kua nplaum thiab/lossis M3 cov ntsia hlau luv.
- Xaub lub pob qhov rooj hla lub hwj chim lub zog ntawm lub tshuab raj.
