Taputapu Papa Aukume Koiri LEEM-1 Helmholtz

Whakaahuatanga Poto:

Kei a ia ngā āhuatanga o te auau rerekē o te tohu whakaoho me te kaha putanga whakarerekētanga.
Ko te ine i te papa aukume porowhita a Helmholtz tētahi o ngā whakamātautau nui i roto i te marautanga whakamātautau ahupūngao o ngā whare wānanga whānui me ngā kāreti hangarau. Ka taea e te whakamātautau te ako me te matatau i te tikanga ine o te papa aukume ngoikore, te whakamatau i te kaupapa taupatupatu o te papa aukume, me te whakaahua i te tohatoha o te papa aukume kia rite ki ngā whakaritenga whakaako.

Ngā ihirangi whakamātautau matua
1. te mātāpono o te ine i te kaha o te aukume mā te aukume hikohiko.
2. te rahi me te tohatoha o te papa aukume kore-taurite o tētahi koiri porowhita kotahi.
3, te rahi me te tohatoha o te papa aukume o te pōkai Helmholtz.

Ngā tawhā hangarau matua
1, Helmholtz pōkai: e rua ngā pōkai he rite te rahi, he rite te radius 100mm, he mokowā waenga.
100mm; te maha o ngā hurihanga o te koiri kotahi: 400 hurihanga.
2, tūāpapa neke-ahu rua kore-aukume, tawhiti neke: whakapae ± 130mm, poutū ± 50 mm. Mā te whakamahi i te aratohu kore-aukume, ka taea te neke tere, kāore he āputa, kāore he rerekētanga whakahoki.
3, koiri kimi: tahuri 1000, koki hurihuri 360 °.
4, awhe auau: 20 ki te 200Hz, taumira auau: 0.1Hz, hapa ine: 1%.
5, ngaru sine: te whānuitanga o te ngaohiko putanga: mōrahi 20Vp-p, te whānuitanga o te iahiko putanga: mōrahi 200mA.
6, Whakaaturanga matihiko LED e toru me te hawhe, mita mirivolt AC: whānuitanga 19.99mV, hapa ine: 1%.
