Uma ufuna ukucisha i-Bluetooth ku "amandla phezu isimo", "cindezela isikhathi eside ukhiye umsebenzi" amasekhondi angu-3, ​​kuze kube ukubaniza osasitini, kungashiwo ivaliwe. Ukuvalwa kwama-headset empeleni kuhlehlisiwe ne ebhuthini, ukubeka headset ebhokisini ukushaja, cisha ibhokisi ukushaja, headset ngokushesha iyanqamula uxhumano lwe-Bluetooth, kuvale phansi bese engena isimo ukushaja.

Ngaphansi kwezimo ezivamile, i-Bluetooth headset ngeke ngokuzenzakalelayo cisha ngemva kwesikhathi Ukukhipha kusukela ukuxhumana nge-Bluetooth. Uma awudingi ke isikhathi esifushane, awudingi ukuba uyivale. Udinga nje kuphela ukuba cisha Bluetooth kwifoni ephathekayo, ngakho ifoni ungagcina amandla, kodwa uma kukhona isikhathi eside. Asikho isidingo ukusetshenziswa, khona-ke kungcono ukuvala, ngakho londoloza amandla

Ulwazi mayelana tws engenantambo Bluetooth kweqiniso

Septhemba 29, 2019

TWS yiyona isifinyezo Wireless True Stereo, TWS ephumelelisa-Bluetooth kweqiniso kwesokunxele kanye isiteshi esifanele ngokwahlukana engenantambo nge-Bluetooth ukuxhumana okungenawaya

1) IP Inkomba ezingeni

IP = Yokungena Ukuvikelwa

IPX1-3 grade: Kubi ukusebenza manzi, kungavimbela okuncane inkungu amanzi.

IPX4: kuvimbela wachela amanzi kusukela ekungeneni.

IPX5: kuvimbela jetting amanzi angangeni manzi nsuku zonke.

IPX6 ezingeni: kungavimbela ngokuphelele amagagasi enkulu bangangeni.

IPX7-8 grade: kungenziwa ofakwe ngokuphelele waterproof

88

2) I-Bluetooth 5.0 ne-Bluetooth 4.2 umehluko

I-Bluetooth 5.0 kuyinto inguqulo ethuthukisiwe ye-Bluetooth 4.2

(1) Ukusebenza kahle yokudlulisela ithuthukisiwe by izikhathi 2; ijubane ukudluliswa yanda, bohlu kuyathuthuka, ukusetshenziswa amandla ancipha kakhulu, futhi ngokukhuthazela kuyathuthuka.

(2) Ibanga ukudluliswa 4 izikhathi ukuthi Bluetooth 4.2.

(3) Lower amandla ukusetshenziswa, iyahambisana Bluetooth inguqulo endala.

(4) I-Bluetooth 4.2 ngokushesha ukwedlula-Bluetooth 4.1

3) Mayelana ukukhuthazela

Ngokuvamile, wireless Bluetooth has a ukuphila kwebhetri amahora 3-6. Nge ibhokisi ukushaja, kungaba ngokuyisisekelo usetshenziselwe 3-4 izikhathi. Kuyinto ukukhuthazela ezinengqondo.

4) Noise ukuncishiswa ulwazi

I NRR umsindo ukunciphisa Inkomba kuyinto segama Neural dor Ucwaningo. Inani umsindo wokwehla earplug ngokuvamile esashiwo NRR, kanye NRR kuyinto kunomsindo attenuation.

Active umsindo kwehliswa ukuncipha umsindo hardware. Isimiso ukusebenzisa circuit eyolanda ezizungezile umsindo kuma, bese siguqulwa isignali nabokhulumile umsindo kuze kube sekupheleni isikhulumi. Umsindo ethulwa indlebe yomuntu ambient umsindo + kuhlehlisiwe umsindo kuma. Kusukela iphuzu enembile umbono, umsindo kuyinto enciphile futhi umzuzi ngokwakhe.

Omunye umsindo ukunciphisa ubuchwepheshe ezinkulu isofthiwe umsindo ukunciphisa, ebizwa nangokuthi i-CVC umsindo ukunciphisa. Kuyinto umsindo isofthiwe ukunciphisa ubuchwepheshe eliza chip CSR. Isebenza kuphela uma ufona. Ngalobu buchwepheshe, imvelo ezungeze umsindo is attenuated. Enye ingxenye uzokwazi ukuzwa izwi sobala.

Njengamanje, TWS earphones ukuthi ingafinyelela asebenzayo umsindo ukunciphisa emakethe ngokuvamile ngempumelelo. Abangane abadinga kuyehlisa umsindo Ungathenga ekhethekile ezemidlalo Bluetooth futhi ekhethekile umsindo ukukhansela-headphone.
