Nkhani yophunzira: Cowin antenna low-frequency rigid board PCB antenna imathandizira chizindikiro chokhazikika chazinthu zama maikolofoni.
Mbiri Yamakasitomala:
Shanghai Loostone Technology ndi bizinesi yapamwamba kwambiri yomwe ikuyang'ana kwambiri pakupanga ndi kupanga zinthu zanzeru zomvera ndi makanema. Ili ku Shanghai. Imagwirizana ndi mitundu yodziwika bwino monga Ali, Baidu, Huawei, Xiaomi, Skyworth, TCL, ndi Jipin. Ndi mtsogoleri mu gawo ofukula.
Zofunikira zamabizinesi:
650-700MHZ mafupipafupi ogwiritsira ntchito, nyumba ndi malo osangalatsa a KTV, mkati mwa utali wa 10M, sikuyenera kukhala kutsekedwa ndi phokoso.
Kufotokozera Kwavuto:
Yankho lapachiyambi la antenna limapangidwa mwachindunji pa bolodi lalikulu la mankhwala. Mlongoti wapa-board womwe timayitana sungathe kutsimikizira zomwe makasitomala ali nazo pamwambapa pakugwiritsa ntchito. Pambuyo poyesedwa kwenikweni, mlongoti woyambirira umangokumana ndi chizindikiro mkati mwa utali wa 2M. Talankhulana ndikukambirana ndi makampani ambiri a tinyanga. Pomaliza, Cowin Antenna adasankhidwa kuti achite kafukufuku ndi chitukuko cha mlongoti wa Q1.
Chovuta
Kukhazikika kwazizindikiro ndi zotsutsana ndi zosokoneza ndizo maziko a mayankho a maikolofoni opanda zingwe. Chifukwa cha kusiyanasiyana kwa zinthu zamagetsi ndi malo ovuta ogwiritsira ntchito omwe ali ndi anthu wandiweyani, chizindikirocho chimasokonezedwa kwambiri, chomwe chimafuna malo okulirapo a mlongoti ndi malo akuluakulu oyambira Kuti akwaniritse zofunikira za mapangidwe a antenna; danga lamkati la maikolofoni ndi 100MM kutalika ndi 25MM mkati mwake. Bwerani ku zovuta zazikulu.
Yankho:
1. Bolodi lalikulu la mankhwalawa limayikidwa mu bokosi lalikulu la bolodi ndikukankhira m'nyumba. Mlongoti uyenera kulumikizidwa ndi bolodi lalikulu kapena bulaketi yayikulu pasadakhale. Poganizira za kupanga misala kotsatira, kuthekera kwa antenna kumangirizidwa mnyumba pasadakhale sikuloledwa.
2. Pali mabatani ogwira ntchito kumbali imodzi ya bokosi la mavabodi, ndipo mlongoti sungakhoze kuikidwa. Njira yokhayo ndikuyika mlongoti kumbali ina. Mbali inayi ndi batire lamphamvu kwambiri. Batire ndiye wakupha wamkulu kwambiri yemwe amakhudza magwiridwe antchito a mlongoti. Izi zimafuna chidziwitso cha akatswiri athu kuti athetse.
3. Mgwirizano wapakatikati ndi kusanthula kwa akatswiri opanga zomangamanga ndi akatswiri opanga ma radio pafupipafupi adasankha kuwonjezera thovu lakudzipatula la 5MM pa PCB ya mlongoti kuti apange mtunda wotetezeka pakati pa mlongoti ndi batire ndikuchepetsa mphamvu ya radiation ya batri pa mlongoti.
4. Kutsimikiza kwa malo a mlongoti ndi malo operekedwa ndi injiniya wa zomangamanga zimatsimikizira kukula kwa mlongoti. Pachifukwa ichi, timatanthauzira kukula kwa mlongoti ngati kutalika kwa 100* m'lifupi 17MM.
5. Kugwiritsa ntchito makina ojambula kumalola akatswiri kuti afupikitse kwambiri nthawi yachitukuko. Pambuyo pa nthawi za 5 za kukonzekera kwachitsanzo cholimba, mlongoti wapawiri wokhala ndi kutalika kwa 100 * m'lifupi 17 * makulidwe a 1MM unapangidwa bwino, ndi phindu la 4.8DB ndi mphamvu ya 44%. Kukhazikika kwa mlongoti kumakhala kokulirapo, komwe kumawongolera bwino mphamvu zotsutsana ndi kusokoneza kwa mlongoti ndikuchita bwino kwambiri pakufalitsa mtunda wautali.
Zopindulitsa pazachuma:
Makasitomala adayambitsa bwino malondawo pamsika, ndipo adakwanitsa kugulitsa mayunitsi a 500,000, ndipo malonda akukulabe.
