Nyaya yekudzidza: Cowin antenna yakaderera-frequency rigid board PCB antenna inobatsira iyo yakagadzikana chiratidzo chezvigadzirwa zvemakrofoni.
Customer Background:
Shanghai Loostone Technology ibhizimusi repamusoro-soro rinotarisa padhizaini nekusimudzira zvigadzirwa zvehungwaru nemavhidhiyo. Inotungamirwa muShanghai. Inoshanda pamwe nemhando dzekutanga-mutsara mhando seAli, Baidu, Huawei, Xiaomi, Skyworth, TCL, uye Jipin. Ndiwo mutungamiri mundima yakatwasuka.
Bhizinesi zvinodikanwa:
650-700MHZ yekushanda frequency, imba uye KTV nzvimbo dzevaraidzo, mukati meradius ye10M, hapafanirwe kuve nekubvisa uye ruzha.
Dambudziko
Iyo yepakutanga antenna mhinduro yakanyatsogadzirirwa pane huru bhodhi yechigadzirwa. Iyo on-board antenna yatinodaidza haigone kuvimbisa zviri pamusoro zvinodiwa nevatengi panguva yekushandiswa. Mushure mekuedzwa chaiko, antenna yepakutanga inongosangana nechiratidzo mukati meradius ye2M. Isu takataurirana uye takakurukura nemakambani mazhinji antenna. Pakupedzisira, Cowin Antenna akasarudzwa kuti aite tsvagiridzo nekuvandudza kweQ1 chigadzirwa antenna.
Dambudziko
Signal kugadzikana uye anti-kupindira ndiwo makona emakrofoni isina waya yekutaurirana mhinduro. Nekuda kwekusiyana-siyana kwezvigadzirwa zvemagetsi uye nharaunda dzekushandisa dzakaoma dzine huwandu hwevanhu, chiratidzo chinokanganiswa zvakanyanya, icho chinoda yakakura antenna chinzvimbo uye yakakura yepasi nzvimbo Kuti isangane neantenna dhizaini zvinodiwa; nzvimbo yemukati yemakrofoni yakareba 100MM uye 25MM yemukati dhayamita. Huya kune dambudziko guru.
Solution:
1. Bhodhi guru rechigadzirwa rinoiswa mubhokisi guru rebhodhi uye rinosundirwa muimba. Iyo antenna inofanirwa kuve yakabatanidzwa kune main board kana main board bracket pamberi. Tichifunga nezve kunotevera kugadzirwa kwemazhinji, mukana wekuti antenna yakasungirirwa mudzimba pamberi inorambidzwa.
2. Kune mabhatani ekushanda kune rumwe rutivi rwebhobhobhobhobhobhobho, uye antenna haigoni kuiswa. Iyo chete sarudzo ndeyekuisa antenna kune rimwe divi. Rimwe divi ibhatiri rinokwanisa kutakura zvakawanda. Bhatiri ndiyo mhondi huru inokanganisa kushanda kweantenna. Izvi zvinoda ruzivo rwehunyanzvi rwemainjiniya edu kuti azvigadzirise.
3. Kudyidzana kwepedyo nekuongororwa kwemainjiniya ezvimiro neredhiyo frequency mainjiniya vakasarudza kuwedzera furo gobvu re5MM pane antenna PCB kugadzira chinhambwe chakachengetedzeka pakati peantenna nebhatiri uye kuderedza kukanganiswa kwemwaranzi yebhatiri paantenna.
4. Kutemerwa kwenzvimbo yeantenna uye nzvimbo yakapihwa neinjiniya yezvimiro zvinotarisa saizi yeantenna. Nechikonzero ichi, isu tinotsanangura saizi yeantenna sehurefu 100* hupamhi 17MM.
5. Kushandiswa kwemuchina wekunyora kunobvumira mainjiniya kupfupisa zvakanyanya nguva yekuvandudza. Mushure me5 nguva yekuomesesa gadziriro yemuenzaniso, antenna-kaviri-panel ine kureba kwe100 * yakafara 17 * ukobvu 1MM yakazogadzirwa zvinobudirira, nekuwana inosvika 4.8DB uye kugona kwe44%. Iyo ivhu reiyo antenna inova yakakura, iyo inovandudza zvakakwana kurwisa-kupindira kugona kweiyo antenna uye nepamusoro pekuita kwekufambisa kureba.
Mabhenefiti ehupfumi:
Mutengi akabudirira kuburitsa chigadzirwa kumusika, uye akawana kutengesa kwe500,000 mayunitsi, uye kutengesa kuchiri kuwedzera.
