Momwe Mungapangire Wailesi Yokhala ndi Kapangidwe Kamakono
Pakati pa kuchulukira kwa nyimbo zotsatsira ndi ma podcasts a digito, wailesi ikadali ndi yakeyake. Phokoso lodziwika bwino la "ofunda", chisangalalo chotembenuza dial, ndi chisangalalo chopeza bwino wailesi yomwe mumakonda - zonsezi zimapereka chidziwitso chosasinthika. Chosangalatsa n'chakuti, mutha kupanga wailesi yanu ndi kapangidwe kamakono komwe kali kokongola ngati chinthu chopangidwa ku fakitale. Nkhaniyi ikufotokoza momwe mungapangire wailesi yokhala ndi mawonekedwe amakono, osavuta kugwiritsa ntchito, osalala, komanso omasuka kugwiritsa ntchito kunyumba kapena pa desiki yanu.
1. Kutanthauzira Lingaliro: Kodi Zamakono Zili Bwanji?
Musanalowe mwatsatanetsatane zaukadaulo, choyamba fotokozani lingaliro lanu la kapangidwe. "Modern" nthawi zambiri imatanthauza:
– Mawonekedwe osavuta komanso oyera: a sikweya kapena ozungulira okhala ndi ngodya zosalala.
- Zipangizo zamakono: acrylic, matabwa osawoneka bwino, aluminiyamu woonda, kapena kuphatikiza kwa zipangizo 2-3.
- Mawonekedwe ochepa: batani limodzi lalikulu, mabatani ochepa ang'onoang'ono, ndi zizindikiro za LED.
– Mitundu yosalowerera: yakuda, yoyera, imvi, yabuluu, kapena matabwa achilengedwe.
Lingaliro ili lidzakhudza kusankha ma module amagetsi, kukula kwa bokosi, ndi kapangidwe ka zigawo kuti ziwoneke zokongola.
2. Sankhani mtundu wa wailesi yoti mupange
Mwachidule, pali njira zingapo zosavuta zopangira wailesi ya DIY:
1. Wailesi ya FM yosavuta: imalandira mauthenga a FM am'deralo.
2. Wailesi ya pa intaneti (Wi-Fi): sewerani malo oimbira wailesi kudzera pa intaneti (yosinthasintha kwambiri).
3. Wailesi yosakanikirana: ili ndi FM ndi Bluetooth/MP3 (yodziwika kwambiri pa DIY yamakono).
Kwa oyamba kumene omwe akufuna zotsatira zachangu komanso mawonekedwe amakono, malangizo enieni kwambiri ndi wailesi ya FM + Bluetooth (kapena FM + MP3 player). Zigawo zake n'zosavuta kuzipeza, dera silovuta kwambiri, ndipo zotsatira zake zimamveka ngati "zomalizidwa."
3. Mndandanda wa Zigawo Zamagetsi Zofunikira
Nazi zigawo zikuluzikulu zomwe zimagwiritsidwa ntchito kwambiri (mungathe kuzisintha):
A. Gawo lolandirira wailesi
- FM module (monga TEA5767 / RDA5807) ngati mukufuna kulamulira kwa digito kudzera pa microcontroller.
– Kapena gawo la wailesi ya FM lomwe lingagwiritsidwe ntchito kale lomwe lili ndi batani lojambulira ndi mawu otuluka.
Ngati mukufuna kukhala ndi zinthu zosavuta, sankhani gawo lokonzeka kugwiritsidwa ntchito. Ngati mukufuna kapangidwe kamakono kokhala ndi zolumikizira zazing'ono komanso zowongolera zazing'ono, gwiritsani ntchito gawo la FM lochokera ku I2C monga RDA5807.
B. Chokulitsa mawu
– PAM8403 (3W) ya wailesi yaying'ono yokhala ndi sipika yaying'ono.
- TPA3110/TPA3116 kuti mupeze mawu amphamvu kwambiri.
– Pa desiki, PAM8403 ndi yokwanira bola ngati ma speaker si akulu kwambiri.
C. Wokamba Nkhani
– Sipika imodzi ya mainchesi atatu (4Ω–8Ω) ndi chisankho chotetezeka.
- Mungagwiritsenso ntchito ma speaker awiri ang'onoang'ono a stereo, koma mukufuna bokosi lalikulu.
D. Zothandizira
– Batire ya 18650 + gawo lochapira (TP4056) kuti lizitha kunyamulika.
– Kapena adaputala ya 5V/2A yogwiritsidwa ntchito kunyumba.
E. Zowongolera & zizindikiro (ngati mukufuna koma pangani kapangidwe kake kukhala kamakono)
- Chojambulira chozungulira (cholumikizira chozungulira) cha voliyumu/kusanthula.
- Batani laling'ono la tact la mode/seek.
- 0.96 inchi OLED kapena chiwonetsero chaching'ono cha pafupipafupi komanso momwe zinthu zilili.
Ndi OLED ndi chogwirira chimodzi, wailesi yanu idzawoneka "yamakono" komanso yapamwamba kwambiri.
4. Zida zogwirira ntchito zomwe ziyenera kukonzedwa
- Solder + tin
- Zodulira zodulira ndi zopumira za mphuno ya singano
- Skuruvu yaying'ono
- Mfuti ya guluu kapena epoxy
- Bowola laling'ono / Dremel kuti mupange mabowo mu bokosi
- Multimeter (yothandiza kwambiri poyang'ana magetsi ndi maulumikizidwe)
Ngati mukufuna chikwama chokongola kwambiri, ganizirani kugwiritsa ntchito acrylic laser cutting kapena 3D printing, koma sikofunikira.
5. Kupanga Nkhaniyi: Chinsinsi cha Maonekedwe Amakono
Chikwamacho ndicho chowonekera kwambiri. Pali njira zingapo zoyenera mapangidwe amakono:
Njira 1: Acrylic (yoyera kapena yosuta)
Akiliriki imapanga mawonekedwe amtsogolo. Mutha kupanga gulu lakutsogolo loyera lokhala ndi mabowo olumikizirana, grille ya sipika yaying'ono, ndi sikirini yaying'ono.
Njira yachiwiri: Matabwa okhala ndi mawonekedwe osawoneka bwino
Matabwa amapereka mawonekedwe amakono a ku Scandinavia. Gwiritsani ntchito paini/plywood, kenako malizitsani ndi utoto wosawoneka bwino kapena utoto wachilengedwe.
Njira 3: Kuphatikiza kwa matabwa ndi acrylic
Mwachitsanzo, thupi la matabwa ndi gulu lakutsogolo la acrylic wakuda wosuta nthawi zambiri limafanana ndi zinthu zapamwamba kwambiri zomvera.
Malangizo amakono opangira ma panel akutsogolo:
- Sungani kufanana ndi mtunda pakati pa zinthu.
- Gwiritsani ntchito batani limodzi lalikulu ngati chizindikiro chachikulu.
- Pangani chophikira chosavuta cha sipika (mizere yopingasa kapena mabowo ozungulira ofanana).
- Chepetsani kuchuluka kwa mabatani omwe akuwoneka.
6. Kusonkhanitsa Chigawo cha Ma Audio
Dongosolo lonse la kayendedwe ka mawu:
Module ya FM / Bluetooth (yotulutsa mawu) → amplifier → wokamba
Masitepe Ofunika:
1. Lumikizani nthaka (GND) pakati pa ma module kuti mupewe phokoso.
2. Gwiritsani ntchito chingwe chachifupi cha mawu kuti muchepetse phokoso.
3. Ngati mukumva phokoso lolira, yesani:
- Onjezani capacitor yolumikizira (monga 100µF + 0.1µF pafupi ndi cholowetsa cha amplifier yamagetsi),
- Konzani mizere ya pansi,
- Siyanitsani chingwe chamagetsi ndi chingwe cha audio.
Pa wailesi ya FM, antenna ndi yofunikanso. Ma module ambiri amafuna chingwe chosavuta cha antenna (monga 70–80 cm). Ikani antenna kutali ndi amplifier kuti muchepetse kusokoneza.
7. Kuphatikiza Kulamulira: Mabatani ndi Mabatani Okongola
Kuti muwoneke wamakono, pewani maswichi akuluakulu ambiri. Zosankha zomwe anthu ambiri amasankha ndi izi:
- Chojambulira chozungulira monga chowongolera voliyumu ndi kuyenda pafupipafupi (zungulirani kuti muwonjezere/kuchepetsa, dinani kuti musinthe mawonekedwe).
- Batani laling'ono la "Mode" kuti musinthe FM/Bluetooth.
– LED yaying'ono yosonyeza mphamvu kapena mawonekedwe a mode.
Ngati mukugwiritsa ntchito microcontroller (monga Arduino Nano/ESP32), mutha kukonza:
- Tembenuzani batani: sinthani ma frequency,
- Dinani batani: sungani zomwe zakonzedweratu,
– Kukanikiza kwa nthawi yayitali: jambulani yokha.
Komabe, ngati mukufuna chinthu chosavuta kwambiri, gwiritsani ntchito gawo lokonzeka kugwiritsidwa ntchito lomwe lili kale ndi batani lojambulira ndi potentiometer yokweza voliyumu.
8. Kumaliza ndi Zambiri Zomwe Zimapangitsa Kuti Ziwoneke Ngati "Zomaliza"
Zinthu zazing'ono zimakhudza kwambiri momwe zinthu zilili komanso khalidwe lamakono:
- Gwiritsani ntchito zolumikizira za aluminiyamu (zopezeka paliponse) kuti mumve bwino kwambiri.
– Zomangira zobisika: gwiritsani ntchito makina otsetsereka kapena maginito ang'onoang'ono pachikuto chakumbuyo.
- Mapazi a rabara pansi pa chivundikiro kuti asaterereke ndikusunga mawonekedwe ake oyera.
- Mabowo ang'onoang'ono opumira mpweya kumbuyo ngati amplifier itatentha mokwanira.
- Konzani zingwezo ndi zomangira zazing'ono ndi guluu kuti zikhale zoyera.
Ngati mukugwiritsa ntchito acrylic, onetsetsani kuti m'mbali mwa nsalu yodulidwayo ndi yosalala. Pa matabwa, mchenga pang'onopang'ono (monga, grit 240-400) musanamalize.
9. Kuyesa, Kukonza, ndi Kukonza
Mlandu usanatsekedwe kwamuyaya:
1. Yang'anani mphamvu ya magetsi yotulutsa magetsi (monga 5V yokhazikika).
2. Onetsetsani kuti gawo la wailesi likulandira mauthenga ndi antenna yolumikizidwa.
3. Yesani kaye voliyumu pamlingo wotsika, kenako muwonjezere pang'onopang'ono.
4. Mvetserani phokoso lililonse mukakhudza chikwamacho—ngati chilipo, yang'anani pansi pake.
Zokonza:
- Pewani kuyika wailesi pafupi ndi ma rauta kapena ma adapter akuluakulu omwe angawonjezere phokoso.
- Ngati mukugwiritsa ntchito mabatire a 18650, gwiritsani ntchito ma cell abwino komanso gawo lotha kuyatsa bwino.
10. Mapeto: Wailesi Yamakono Yopangidwa Pakhomo Ndi Yotheka Kwambiri
Kupanga wailesi yamakono sikuti ndi nkhani ya zamagetsi zokha, komanso kukongola: kapangidwe kake, zipangizo, ndi tsatanetsatane womaliza. Ndi FM module yomwe ilipo mosavuta, amplifier yaying'ono, ma speaker oyenera, ndi kachikwama kakang'ono ka acrylic kapena matabwa, mutha kupanga wailesi yokongola, yogwira ntchito, komanso yopangidwa mwaluso.
Ngati mukufuna, ndingakuthandizeni kupanga mtundu wina wapadera: kusankha zigawo kutengera bajeti (yapakati-yapamwamba), njira yosavuta yolumikizira mawaya, kapena kapangidwe ka gulu lakutsogolo (kukula kwa kapangidwe ndi malo olumikizirana/okamba/chinsalu) malinga ndi kukula komwe mukufuna.
