He aha te take e whakamahia ai ngā whakawhiti ultrasonic?
E whakamahia whānuitia ana ngā whakawhiti hiko ultrasonic (pērā i ngā whakawhiti FUNSONIC) i roto i te umanga ultrasonic. Ka whakaputahia e ngā uku piezoelectric kounga teitei ngā ngaru ultrasonic i roto i te whakawhiti, ka whakanuia ki te taumata teitei o te taputapu ka whakaoho i ngā wiri i roto i te reo whāinga.
Ko te tūranga o te puranga uku piezoelectric he wāhanga nui o te hoahoa arotau irahiko. Nō roto ngā uku piezoelectric i te rōpū rauemi hiko-ukara, tae atu ki ngā āhuatanga hiko, miihini, me te aukume. Ka hurihia e ngā irahiko ultrasonic te hiko hiko hei pūngao miihini; ka hipokina e tā rātou whānuitanga mahi ngā auau mai i te DC ki ngā megahertz maha. Mō ngā mahi tukunga ultrasonic (ngā auau kei runga ake i te whānuitanga o te whakarongo tangata), ka mahi ngā irahiko ultrasonic me te oro, me ngā auau oro noa i waenga i te rua rau kHz me te 10 MHz. Ka taea e ngā irahiko piezoelectric ultrasonic te tango i ngā rerekētanga ahotea iti rawa, ka hurihia hei tohu hiko.
He aha ngā whakamahinga o ngā transducers ultrasonic?
Ko te pūwhakawhiti ultrasonic (pūoko) he mīhini e whakamahia ana hei huri i te kaha hiko ki te kaha miihini, hei huri rānei. Ko tētahi o ngā pūwhakawhiti tino rongonui—te koiri reo—e whakamahia ana i roto i ngā woofers me te nuinga o ngā kaikorero. Ka hurihia te kaha hiko hei nekehanga miihini, ka hurihia hei ngaru oro. Ko ngā horoi ultrasonic, ngā rehu atomizing ultrasonic, me ngā probes ultrasound he tauira katoa o ngā whakamahinga mō ngā pūwhakawhiti ultrasonic. Kei roto i ēnei whakamahinga, engari kāore i te herea ki, ēnei i roto i te umanga pūtaiao, te aunoatanga ahumahi, te ahuwhenua me te whakatipu kararehe, te tiaki taiao, me te ope taua. Ka whakamahia e ia pūoko waka he pūwhakawhiti ultrasonic piezoelectric hei ine i te tawhiti; hei tauira, ka whakamahia hoki ngā pūwhakawhiti ultrasonic piezoelectric hei whakatūpato i ngā kaiwhakahaere mō ngā herenga mā te tangi haruru.
He aha te take e whakamahia ai ngā whakawhiti ultrasonic?
He maha ngā painga o ngā transducers ultrasonic ki ngā momo transducers rerekē. He mea hanga katoa ēnei i runga i ngā rauemi piezoelectric totoka, he mea hanga i ngā uku piezoelectric, ka huri i te āhua ina whakamahia he ngaohiko. E mōhiotia ana tēnei ko te pānga piezoelectric whakamuri. I tetahi atu taha, ina whakamahia te taumahatanga miihini ki te transducer piezoelectric, ka puta he utu hiko, e mōhiotia ana hoki ko te pānga piezoelectric tika. I kitea tuatahitia tēnei pānga piezoelectric e ngā teina Curie neke atu i te kotahi rau tau ki muri. Ko ēnei transducers ultrasonic piezoelectric ka whakamahia i roto i te ultrasonic sonar echolocation, ngā pūoko tawhiti, ngā pūoko rere, ngā pūoko nekehanga, me ētahi atu. Ka mahi ngā transducers ultrasonic i roto i te aratau tuku me te kaiwhiwhi, ka aromatawai i te kaha wā, tohu rānei, ka huri hei ine. Ko ētahi o ngā painga o ngā transducers ultrasonic piezoelectric ko te iti o te rahi, te pakari, te ngāwari o te rahi, te āhua, me te āhua, te kore tiaki, te roa o te ora o te pūoko, me te ngāwari o te whakahaere.
