Lalela Ngedivayisi Yezindonga Nge-High Sensitivity Audio Acoustic Microphone
Isithombe somkhiqizo
Incazelo
Idivayisi ethi Lalela Ngezindonga ene-High Sensitivity Audio Acoustic Microphone ingathola futhi irekhode amasiginali womsindo we-analogi (izwi lomuntu, izinyathelo, eminye imisindo).Ngenxa yokwamukelwa kwemishini yokucutshungulwa kwe-DSP enomsindo ophansi ekhombisayo, isiginali ithathwa yizinzwa ezizimele ze-stereo kwesokunxele nakwesokudla ekugcineni, bese ikhipha ngemuva kokwehliswa kweyunithi yokucubungula iyunithi ngemuva, ngakho umshini. ikwazi ukuzwa imisindo emincane kakhulu.
Isistimu ingathatha umsindongokusebenzisaisakhiwo izindonga, usilingi, phansi, njll. Inzwa yangaphandle ixhunywe ku-amplifier yomsindo enikeza ukulawulwa kwevolumu ethintekayo kumashaneli angakwesokunxele nangakwesokudla, kanye nokurekhoda kwedrayivu ye-USB yangaphandle.Ingumholi wohlobo olufanayo lwemikhiqizo ngokunikeza umphumela wokulalela onembile, ozwelayo kanye nencazelo ephezulu kanye nonyaka wokurekhoda nesikhathi.Kuzwakala ngezakhiwo ezifana nezindonga, uphahla kanye naphansi, njengasezindaweni lapho kugcinwe khona abathunjwa.
Itangeke isetshenziswe kuphela njengamabutho akhethekile imishini yokuqapha ngokushesha, kodwa futhi amaphoyisa ezempi, uphenyo lobugebengu, iminyango yophenyo lwezobuchwepheshe yophenyo kanye nokulwa nokubhekwa kwemikhiqizo edingekayo.
Izici
- Ukucubungula kwe-algorithm yomsindo eyakhelwe ngaphakathi ye-DSP enamandla, ukuze kuqinisekiswe ikhwalithi yomsindo yokuqapha engcono kakhulu.
- Inzwa eyenziwe ngokwezifiso yomsindo yokuhlukanisa, ukudlidliza kokudlulisa inzwa yokwethuka ngomsindo ophansi kakhulu weamplifier +DSP processing, ngisho nesignali yomsindo ebuthakathaka kakhulu ingazwakala.
- Ngezinzwa zomsindo ezichwepheshile, isiteshi 1 noma isiteshi 2, noma kokubili okulalelayo.
- Ngemuva kokukhishwa kokucubungula kwe-DSP, iziteshi ezimbili zingarekhodwa kanyekanye.
- Imodi yokuqapha: ihedisethi enezintambo, ihedisethi ye-Bluetooth engenantambo, ukurekhoda.
- Ukusebenza kochwepheshe nokuthinta komuntu siqu + kokudlidliza.

Isingeniso Senkampani
Ngo-2008, i-Beijing Hewei Yongtai Technology Co., LTD yasungulwa e-Beijing.Gxila ekuthuthukisweni nasekusebenzeni kwemishini ekhethekile yokuphepha, ikakhulukazi esebenzela umthetho wezokuphepha komphakathi, amaphoyisa ahlomile, amasosha, amasiko kanye neminye iminyango yezokuphepha kazwelonke.
Ngo-2010, i-Jiangsu Hewei Police Equipment Manufacturing Co., LTD yasungulwa eGuannan.Ihlanganisa indawo engamamitha-skwele angama-9000 weshabhu nokwakhiwa kwamahhovisi, ihlose ukwakha isisekelo sokuqala socwaningo lwemishini yokuphepha ekhethekile kanye nentuthuko eChina.
Ngo-2015, i-Rese yamaphoyisa ezempiarch kanye nesikhungo sokuthuthukiswa kwamiswa e-Shenzhen.Ukugxila ekuthuthukisweni kwemishini ekhethekile yokuphepha, sekusungule izinhlobo ezingaphezu kuka-200 zemishini yokuphepha yochwepheshe.
Imibukiso yaphesheya kwezilwandle
Izitifiketi
I-Beijing Heweiyongtai Sci & Tech Co., Ltd. ingumnikezeli Oholayo we-EOD kanye Nezixazululo Zokuphepha.Abasebenzi bethu bonke bangochwepheshe abaqeqeshiwe nabaphathi ukuze bakunikeze isevisi eyanelisayo.
Yonke imikhiqizo inemibiko yokuhlolwa kwezinga lochwepheshe kazwelonke kanye nezitifiketi zokugunyazwa, ngakho-ke sicela uqiniseke ngoku-oda imikhiqizo yethu.
Ukulawulwa kwekhwalithi okuqinile ukuze kuqinisekiswe impilo ende yesevisi yomkhiqizo kanye nomsebenzisi usebenza ngokuphepha.
Ngesipiliyoni sembonini seminyaka engaphezu kwe-10 se-EOD, imishini yokulwa nobuphekula, idivayisi yezobunhloli, njll.
Sisebenze ngokusemthethweni amaklayenti angaphezu kwamazwe angama-60 emhlabeni jikelele.
Ayikho i-MOQ yezinto eziningi, ukulethwa okusheshayo kwezinto ezenziwe ngezifiso.
