Isisetshenziswa sejubane lomsindo se-LMEC-15B (i-Resonance Tube) Isithombe Esifakiwe

Isisetshenziswa sejubane lomsindo se-LMEC-15B (iThubhu Lokuzwakala)

Incazelo emfushane:

Le nsimbi isebenzisa izikhulumi ukuze ikhiqize amaza omsindo azwakalayo anomvamisa oguquguqukayo oqhubekayo, ozwakala emoyeni ukuze kulinganiswe ubude bamaza omsindo, kulinganiswe ijubane lomsindo ozwakalayo, futhi kufundwe ubudlelwano phakathi kwesivinini somsindo kanye nomvamisa.
Uma kuqhathaniswa nemishini endala, ikholomu yamanzi inezinzuzo zobubanzi obukhulu bokuhamba, imvamisa yokulinganisa eguquguqukayo njalo, ukunemba okuphezulu kwemiphumela yokulinganisa, ukusetshenziswa okulula kanye nesakhiwo esiqinile.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa

1. Qaphela igagasi lokuma elizwakalayo epayipini lomsindo

2. Linganisa ijubane lomsindo

Imininingwane yobuchwepheshe eyinhloko
1. Ishubhu yokuzwana: udonga lweshubhu luphawulwe ngesikali, ukunemba kwesikali kungu-1 mm, kanti ubude obuphelele abungaphansi kuka-95 cm; Ubukhulu: ubude obusebenzayo bungaba ngu-1 m, ububanzi bangaphakathi bungu-34 mm, ububanzi bangaphandle bungu-40 mm; Izinto: i-plexiglass esobala esezingeni eliphezulu;
2. I-funnel yensimbi engagqwali: yokwengeza amanzi. Ingasuswa kalula uma ingasetshenziswa, futhi ayithinti ukunyakaza kokukhuphuka nokuhla kwesitsha samanzi uma sibekwa esitsheni samanzi ngesikhathi sokuhlola;
3. Ijeneretha yamagagasi omsindo elungisekayo (umthombo wesignali): ububanzi bemvamisa: 0 ~ 1000Hz, elungisekayo, ehlukaniswe ngamabhendi amabili emvamisa, isignali iyigagasi le-sine, ukuhlanekezela ≤ 1%. Imvamisa iboniswa yimitha yemvamisa, futhi ubukhulu bokukhipha amandla bulungiswa njalo ukuze kufezwe umphumela wevolumu yesipikha elungisekayo;
4. Isitsha samanzi: phansi kuxhunywe nethubhu ye-resonance ngethubhu yerabha ye-silicone, kanti phezulu kugcwaliswa kalula ngamanzi nge-funnel; Ingahamba phezulu naphansi ngepali eqondile, futhi ngeke ishayisane nezinye izingxenye;
5. Isipikha esikhulu (uphondo): amandla angaba ngu-2Va, ububanzi bemvamisa bungu-50-2000hz;
6. Ibhulakhethi: kufaka phakathi ipuleti eliyisisekelo esindayo kanye nensika esekelayo, esetshenziselwa ukusekela ithubhu elizwakalayo kanye nesitsha samanzi.
