(4) Biko afụla ikuku na ngwaahịa ozugbo.
Ikuku na-efe efe na-emetụta ike na piezoelectric diaphragm site na oghere mgbapụta ụda;mgbawa nwere ike ime na mgbe ahụ ụda nwere ike ịghọ ihe na-adịghị akwụsị akwụsị.Na mgbakwunye, enwere ike na ikpe ahụ nwere ike ịpụ.
Ọkwa (Jikwaa)
1. A na-eji seramiiki Piezoelectric na ngwaahịa a.Biko jiri nlezianya mee ihe na njikwa, n'ihi na seramiiki na-agbaji mgbe etinyere oke ike.
2. Biko etinyela ike na diaphragm piezoelectric site na oghere ụda ụda.Ọ bụrụ na itinye ike n'ọrụ, mgbawa na-apụta na ụda nwere ike ịghaghachị.
3. Biko atụbakwala ngwaahịa ma ọ bụ tinye ujo ma ọ bụ mgbanwe okpomọkụ na ya.Ọ bụrụ otu a, enwere ike ibibi LSI site na ụgwọ (voltaji na-agbapụta) ewepụtara.na-egosi ihe atụ sekit ịkwọ ụgbọala na-eji zener diode.
Ọkwa (ịnya ụgbọ ala)
1. Ag Mbugharị nwere ike ime ma ọ bụrụ na DC voltaji etinyere ngwaahịa n'okpuru a elu iru mmiri gburugburu ebe obibi.Biko zere iji ya n'okpuru oke iru mmiri ma chepụta sekit ka ị ghara itinye voltaji DC.
2. Mgbe ị na-ebu ngwaahịa site na IC, biko tinye nguzogide 1 na 2kΩ n'usoro.Ebumnuche bụ ichekwa IC na ịnweta ụda kwụsiri ike.(Biko lee foto 2a).
Ịtinye diode n'otu aka ahụ na ngwaahịa ahụ nwere otu mmetụta ahụ.(Biko lee foto 3b)
3. Flux ma ọ bụ mkpuchi mkpuchi, wdg, ihe mgbaze dị iche iche
Ọ ga-ekwe omume na ihe mgbaze mmiri na-abanye n'ime ngwaahịa ahụ, ebe ọ bụ na ngwaahịa a abụghị ihe eji emechi.Ọ bụrụ na mmiri batara n'ime ma tinye ya na piezoelectric diaphragm, enwere ike igbochi ịma jijiji ya.Ọ bụrụ na ijikọ na njikọ eletrik, njikọ eletrik nwere ike ịda.
Iji gbochie ndakpọ ụda, biko ekwela ka mmiri banye n'ime ngwaahịa a.
