Ii-headsets zeziko leefowuni ziyilelwe ukuhanjiswa kwelizwi, ikakhulu eziqhagamshela iifowuni okanye iikhompyutha ukuze zisetyenziswe eofisini nakwiziko lemibuzo. Iimpawu zabo eziphambili kunye nemigangatho ziquka:
1.Narrow frequency bandwidth, elungiselelwe ilizwi. Ii-headsets zefowuni zisebenza ngaphakathi kwe-300-3000Hz, zigubungela ngaphezulu kwe-93% yamandla entetho, iqinisekisa ukuthembeka kwelizwi okugqwesileyo ngelixa ucinezela ezinye iifrikhwensi.
I-2.I-microphone ye-electret yobuchwephesha ekusebenzeni okuzinzileyo. Iimakrofoni eziqhelekileyo zihlala zithomalalisa ubuntununtunu ngokuhamba kwexesha, zibangela ukugqwetheka, ngelixa ii-headsets zeziko lonxibelelwano ziwunqanda lo mba.
3.Ikhaphukhaphu kwaye ihlala ixesha elide. Eyenzelwe ukusetyenziswa ixesha elide, ezi headsets ibhalansi intuthuzelo kunye nokusebenza.
4.Ukhuseleko kuqala. Ukusetyenziswa kwe-headset ixesha elide kungonakalisa ukuva. Ukunciphisa oku, ii-headsets zeziko lomnxeba zibandakanya ukujikeleza okukhuselekileyo, ukuthobela imigangatho yamazwe ngamazwe:
I-UL (Underwriter's Laboratories) imisela umda wokhuseleko we-118 dB ngokutyhileka ngequbuliso kwingxolo.
I-OSHA (uKhuseleko eMsebenzini kunye noLawulo lwezeMpilo) inqanda ukuba sesichengeni sengxolo ixesha elide kwi-90 dBA.
Ukusebenzisa ii-headsets kwiziko leefowuni kukhulisa ukusebenza kakuhle kwaye kunciphisa iindleko.
Izixhobo: Uqhawulo olukhawulezayo (i-QD) iintambo, izixhobo zokucofa, izidayili ze-ID yomnxeba, ii-amplifiers, kunye namanye amacandelo.
Ukukhetha umgangatho we-headset:
Ukucaca komsindo
Ukuhanjiswa kwelizwi elicacileyo, lendalo ngaphandle kokugqwetheka okanye ukuma.
Ukwahlula ingxolo okusebenzayo (ukunciphisa ingxolo engqongileyo ≥75%).
Ukusebenza kwemakrofoni
Imakrofoni ye-electret yodidi lobuchwephesha enovakalelo olungaguqukiyo.
Ucinezelo lwangasemva lwengxolo yomsindo okroliweyo wangaphakathi/ophumayo.
Uvavanyo lokuqina
I-Headband: Isinda kwi-30,000+ imijikelo ye-flex ngaphandle komonakalo.
Ingalo eBoom: Ixhathisa 60,000+ yeentshukumo ezijikelezayo.
Ikhebula: Ubuncinci be-40kg amandla okuqina; iindawo zoxinzelelo eziqinisiwe.
Ergonomics kunye nentuthuzelo
Uyilo olulula (ngokuqhelekileyo phantsi kwe-100g) kunye neendlebe eziphefumulayo.
I-headband ehlengahlengiswayo yokunxiba ixesha elide (iiyure eziyi-8+).
Ukuthotyelwa koKhuseleko
Idibana ne-UL/OSHA yemida yokuvezwa kwengxolo (≤118dB incopho, ≤90dBA eqhubekayo).
Isekethe eyakhelwe-ngaphakathi ukukhusela i-audio spikes.
Iindlela zoVavanyo:
Uvavanyo lweNdawo: Linganisa iiseshini zokufowuna iiyure eziyi-8 ukujonga intuthuzelo kunye nokubola komsindo.
Uvavanyo loxinzelelo: Iplagi ngokuphindaphindiweyo / ukhuphe izixhumi ze-QD (i-20,000+ cycles).
Uvavanyo lokulahla: Imitha ye-1 iwela kwiindawo eziqinileyo akufanele ibangele umonakalo osebenzayo.
Ingcebiso yePro: Jonga isiqinisekiso se- "QD (Ukuqhawula ngokukhawuleza)" kunye newaranti yeminyaka emi-2+ evela kwiimpawu ezibonisa ukuthembeka komgangatho weshishini.
