Bluetooth Headset ndi mutu womwe umagwiritsa ntchito ukadaulo wopanda zingwe kulumikiza zida monga mafoni am'manja ndi makompyuta. Amatilola kusangalala ndi ufulu wambiri komanso chitonthozo tikamamvera nyimbo, kuyimba foni, kusewera masewera, ndi zina zambiri. Kodi amathandizira bwanji kuyankhulana opanda zingwe ndi kukonza zomvera?
Yankho ndiloti pali gulu lozungulira kwambiri komanso lovuta kwambiri (PCB) mkati mwa mutu wa Bluetooth. Bolodi la dera ndi bolodi lomwe lili ndi waya wosindikizidwa, ndipo ntchito yake yaikulu ndi kuchepetsa malo omwe amapangidwa ndi waya ndikukonza waya molingana ndi dongosolo lomveka bwino. Zida zosiyanasiyana zamagetsi zimayikidwa pa bolodi la dera, monga maulendo ophatikizika, resistors, capacitors, crystal oscillators, ndi zina zotero, zomwe zimagwirizanitsidwa wina ndi mzake kudzera m'mabowo oyendetsa ndege kapena mapepala pa bolodi la dera kuti apange dongosolo lozungulira.
Gulu lozungulira la mutu wa Bluetooth nthawi zambiri limagawidwa m'magawo awiri: bolodi lalikulu lowongolera ndi bolodi yolankhula. Gulu lalikulu loyang'anira ndilo gawo lalikulu la mutu wa Bluetooth, womwe umaphatikizapo Bluetooth module, audio processing chip, chip kasamalidwe ka batri, chip charging, key chip, indicator chip ndi zigawo zina. Bungwe lalikulu lolamulira liri ndi udindo wolandira ndi kutumiza zizindikiro zopanda zingwe, kukonza deta yomvera, kulamulira batri ndi kuyitanitsa udindo, kuyankha ntchito yaikulu, kusonyeza ntchito yogwirira ntchito ndi ntchito zina. Bolodi yolankhula ndi gawo lotulutsa lamutu wa Bluetooth, womwe uli ndi choyankhulira, maikolofoni, gawo lochepetsera phokoso ndi zigawo zina. Bolodi yolankhulayo ili ndi udindo wosintha siginecha yamawu kuti ikhale yotulutsa mawu, kusonkhanitsa mawu, kuchepetsa kusokoneza kwa phokoso ndi ntchito zina.
Chifukwa chakuchepa kwa mahedifoni a Bluetooth, ma board awo ozungulira nawonso ndi ang'ono kwambiri. Nthawi zambiri, kukula kwa bolodi yayikulu yoyang'anira chamutu cha Bluetooth ndi pafupifupi 10mm x 10mm, ndipo kukula kwa bolodi yolankhula ndi pafupifupi 5mm x 5mm. Izi zimafuna kupanga ndi kupanga bwalo la dera kuti likhale labwino kwambiri komanso lolondola kuti zitsimikizire kukhazikika ndi kudalirika kwa dera. Pa nthawi yomweyi, chifukwa mutu wa Bluetooth uyenera kuvala pa thupi la munthu ndipo nthawi zambiri umakhala ndi thukuta, mvula ndi malo ena, matabwa awo ozungulira amafunikanso kukhala ndi mphamvu zotsutsana ndi madzi komanso zowonongeka.
Mwachidule, pali bolodi lozungulira kwambiri komanso lovuta kwambiri (PCB) mkati mwa Bluetooth headset, yomwe ndi gawo lofunikira kwambiri pakuyankhulirana opanda zingwe ndi kukonza ma audio. Palibe bolodi lozungulira, palibe chomangira cha Bluetooth.
