Bluetooth headset iheadset inoshandisa tekinoroji isina waya kubatanidza zvishandiso zvakaita senharembozha nemakomputa. Vanotibvumira kuti tinakidzwe nerusununguko rwakawanda uye kunyaradzwa kana tichiteerera mimhanzi, kuita foni, kutamba mitambo, nezvimwewo. Asi wakambozvibvunza here kuti chii chiri mukati mehedhifoni yakadaro? Vanogonesa sei kutaurirana newireless uye audio processing?
Mhinduro ndeyekuti kune yakanyanya kuoma uye yakaoma redunhu bhodhi (PCB) mukati meiyo Bluetooth headset. Bhodhi redunhu ibhodhi rine tambo yakadhindwa, uye basa rayo guru nderokuderedza nzvimbo inobatwa netambo uye kuronga tambo maererano nekugadzirisa kwakajeka. Zvikamu zvakasiyana-siyana zvemagetsi zvakaiswa pabhodhi redunhu, zvakadai semasekete akabatanidzwa, resistors, capacitors, crystal oscillators, nezvimwewo, izvo zvakabatanidzwa kune mumwe nemumwe kuburikidza nemakomba ekufambisa kana mapedhi pabhodhi redunhu kuti rigadzire hurongwa hwedunhu.
Bhodhi redunhu reBluetooth headset rinowanzo kupatsanurwa kuita zvikamu zviviri: iyo huru yekudzora bhodhi uye bhodhi remutauri. Iyo huru control board ndiyo yakakosha chikamu cheBluetooth headset, iyo inosanganisira Bluetooth module, audio processing chip, bhatiri manejimendi chip, yekuchaja chip, kiyi chip, chiratidzo chip uye zvimwe zvinhu. Iyo huru yekudzora bhodhi ine basa rekugamuchira uye kutumira masaini masaini, kugadzirisa odhiyo data, kudzora bhatiri uye yekuchaja mamiriro, kupindura kukiyi mashandiro, kuratidza chimiro chekushanda uye mamwe mabasa. Iyo speaker board ndiyo inobuda chikamu cheBluetooth headset, iyo ine mutauri unit, maikorofoni unit, ruzha rwekudzikisa ruzha uye zvimwe zvikamu. Bhodhi rezvitauriri rine basa rekushandura chiratidzo cheodhiyo kuita ruzha, kuunganidza kuisa ruzha, kuderedza kukanganiswa kweruzha uye mamwe mabasa.
Nekuda kwehukuru hudiki hwemahedhifoni eBluetooth, mabhodhi avo edunhu zvakare madiki. Kazhinji kutaura, saizi yebhodhi huru yekudzora yeBluetooth headset ingangoita 10mm x 10mm, uye saizi yebhodhi rekutaura ingangoita 5mm x 5mm. Izvi zvinoda kuti dhizaini nekugadzirwa kwebhodhi redunhu rive rakanyanya kunaka uye rakananga kuti ive nechokwadi chekugadzikana uye kuvimbika kwedunhu. Panguva imwecheteyo, nekuti iyo Bluetooth headset inoda kupfekwa pamuviri wemunhu uye kazhinji inofumurwa dikita, mvura uye dzimwe nharaunda, mabhodhi avo edunhu anodawo kuve nehumwe husina mvura uye hunopesana nekuora.
Muchidimbu, pane yakanyanya kuomarara uye yakaoma redunhu bhodhi (PCB) mukati meBluetooth headset, inova chikamu chakakosha chekutaurirana pasina waya uye odhiyo kugadzirisa. Hapana bhodhi redunhu, hapana Bluetooth headset.
