1. He aukume hiko kei te pūoro aukume me te matua rino neke i waenganui i ngā pou e rua o te aukume tuturu. Ina kore he au i roto i te koiri o te aukume hiko, ka kukumea te matua rino neke e te kukume taumata-wāhanga o ngā pou aukume e rua o te aukume tuturu, ā, ka noho tonu ki waenganui; Ina rere te au i roto i te koiri, ka aukumetia te matua rino neke, ā, ka huri hei aukume pae. I te huringa o te ahunga o te au, ka huri anō hoki te polarity o te aukume pae, kia huri ai te matua rino neke huri noa i te pūtahi, ā, ka tukuna te wiri o te matua rino neke mai i te cantilever ki te diaphragm (kone pepa) hei pana i te hau kia wiri wera.

2. Pūoro Hiko-pūmau He pūoro tēnei e whakamahi ana i te kaha hiko-pūmau kua tāpirihia ki te pereti pūnga. Mō tōna hanganga, ka kiia hoki he pūoro pūnga nā te mea he ritenga kē ngā irahiko pai me te kino tetahi ki tetahi. E rua ngā rauemi matotoru, mārō hoki e whakamahia ana hei pereti pumau, ka taea te tuku oro mā roto i ngā pereti, ā, ko te pereti waenga he mea hanga ki ngā rauemi angiangi, māmā hoki hei whāriki (pērā i ngā whāriki konumohe). Whakamaua, whakakīia hoki te whāriki, kia tawhiti rawa atu i te pou pumau. Ahakoa i runga i te whāriki nui, e kore e tukinga ki te pou pumau.
3. Ngā Kaikōrero Piezoelectric Ko te kaikōrero e whakamahi ana i te pānga piezoelectric whakamuri o ngā rauemi piezoelectric ka kiia he kaikōrero piezoelectric. Ko te āhuatanga e whakapororaru ana te dielectric (pērā i te quartz, te potassium sodium tartrate me ētahi atu tioata) i raro i te mahi a te pēhanga, ka puta he rerekētanga pūmanawa i waenga i ngā pito e rua o te mata, ka kiia ko te "pānga piezoelectric". Ko tōna pānga whakamuri, arā, ko te whakarerekētanga rapa o te dielectric kua whakanohoia ki roto i te mara hiko, ka kiia ko te "pānga piezoelectric whakamuri" te "hiko whakawhāiti" rānei.
