Kamudzira kedhaimani kanodedera uye nzira yaro yekugadzira, kachipfuura nesimba risingaenzaniswi (senge waya inodzivisa kupisa, plasma, murazvo) rinomutsa gasi rakaparadzana pamusoro pechiumbwa, richishandisa daro riri pakati penzvimbo yakakombama yechiumbwa nesimba risingaenzaniswi rinomutsa gasi rakaparadzana. Kusiyana kunogadzira mhedzisiro dzakasiyana dzekupisa. Kana zvinhu zvedhaimani zvakafukidzwa pamusoro pechiumbwa, kukura kwezvinhu zvedhaimani kwakasiyana, zvekuti firimu redhimoni redhimoni rine hunhu hwedhimoni husingaenzaniswi, zvekuti firimu redhimoni redhimoni rine bandwidth yakakura yekuteerera.
Pakusarudza zvinhu zviri padiaphragm, zvinhu zvikuru zvinofanira kufungwa nezvazvo kuomarara uye hunhu hwekunyorovesa. Kuomarara kunoratidza kuwanda kwechisikigo kwezvinhu, uye kuwanda kwechisikigo kwezvinhu zvine kuomarara kwakanyanya, uye zvinopesana, kuwanda kwechisikigo kwezvinhu zvine kuomarara kwakadererawo. Zvinhu zvine hunhu hwakanaka hwekunyorovesa zvinogona kuita kuti membrane inodedera ive nemhinduro yakapfava yekudedera, zvichiita kuti kumanikidzwa kwenzwi rinobuda kwemembrane inodedera kuve kwakapfava.
Zvinhu zvinowanzo shandiswa pakugadzira membrane zvinosanganisira bepa, purasitiki yepolymer, simbi (Be, Ti, Al), ceramics, nezvimwewo. Mapepa ne polymer zvinhu zvine hunhu hwakanaka hwekunyorovesa, asi kuomarara kwakashata uye kukuvara kuri nyore, uye kuomarara kwakaderera hakuna kukwana kuti zviite. Kushanda kwakanyanya kwakaganhurirwa. Kunyangwe firimu rinodedera resimbi rine kuomarara kuri nani, simbi dzakaomarara dzakadai seBe, Ti, nezvimwewo dzinodhura uye dzakaoma kugadzirisa. Zvinhu zveceramic zvinewo dambudziko rekuita kwakaomarara kwekupisa. Nekuda kwehunhu hwakanaka hwemakanika uye simba rezvinhu zvedhaimani, yakakodzera kugadzirwa kwema diaphragm akareruka, ane kuomarara kwakanyanya, uye inogona kushandiswa mumaspika epakati nepamusoro. Ruzha rwunodiwa runogadzirwa kuburikidza nekufamba kwenguva kwe diaphragm. Kuwanda kwekufamba kwenguva kwe diaphragm, simba remakanika uye zvinodiwa zvemhando yepamusoro zve diaphragm, uye kushandiswa kwezvinhu zvedhaimani kugadzira diaphragm kunogona kuzadzisa chinangwa ichi.
Kazhinji, membrane inodedera ine muganho wepamusoro wefrequency yekupindura. Zvisinei, zvisinei nekuti membrane inodedera yakagadzirwa nedhaimani kana zvimwe zvinhu, frequency yechisikigo inogumira kune imwe nzvimbo nekuda kwehunhu hwayo hwese, izvo zvinoderedza mashandiro ayo ebandwidth. Hunhu hwekudambisa uye kuomarara hazvigone kuchinjwa zvisina tsarukano, izvo zvinoderedza kunaka kweruzha rwayo uye mashandiro etimbre. Saka, kana uchida kufukidza frequency range inogamuchirwa nenzeve yemunhu, unowanzo fanirwa kuisa diaphragms dzakawanda dzine bandwidth dzakasiyana uye frequency upper limits panguva imwe chete kuti uwane mhedzisiro yakanaka yeruzha. Naizvozvo, mune art yapfuura, kune tekinoroji yekushandisa zvinhu zvakasiyana kugadzira membrane inodedera muzvikamu. Chikamu chepakati che membrane inodedera chakagadzirwa nezvinhu zvine kuoma kwakanyanya, uye rin'i yekunze yakagadzirwa nezvinhu zvine kuoma kwakaderera. Zvadaro zvikamu zviviri izvi zvinobatanidzwa kuti zviite imwe chete. membrane inodedera ine kuoma kwakawanda uye ukobvu panguva imwe chete, uye inogona kufukidza bandwidth yakakura. Zvisinei, ukobvu hwefirimu inodedera hunowanzo kutetepa zvakanyanya, uye basa rekubatanidza rakaoma. Kana ichizoshandiswa pazvinhu zvedhaimani, tekinoroji yayo yekubatanidza uye chinhu chinobatanidza zvinhu idambudziko guru, saka hazvisi nyore kuisa pazvinhu zvedhaimani.
Kuti tigadzirise matambudziko ari pamusoro apa, chigadzirwa ichi chinokurudzira firimu rinodedera redhaimani nenzira yaro yekugadzira, iyo inogona kushandura kuomarara, ukobvu uye hunhu hwekudambisa hwenzvimbo dzakasiyana pafirimu rinodedera redhaimani, kuitira kuti rive nehunhu hwekudedera husina kufanana uye hunobatanidza huwandu hwakawanda hwema frequency.
Zvichienderana nedhaimani rinodedera uye nzira yaro yekugadzira yakaburitswa mukugadzirwa uku, chiumbwa chine pamusoro wakakombama chinopihwa, uye simba risingafanane (risina kufanana) rinomutsa gasi rakaparadzaniswa rinopfuura nepamusoro pechiumbwa kuti rigadzire tembiricha yepamusoro yekupisa chiumbwa kuitira kuti pamusoro pechiumbwa pave nekupararira kwetembiricha isina kuenzana.
Semuenzaniso ne
1. Waya inodzivisa kupisa ndiyo nzvimbo iri pakati (nzvimbo ine simba rakawanda), uye huwandu hwechinhu chinopindura hunoratidza kugoverwa kweringi isina kuenzana.
2. Nekuda kwemhedzisiro yewavelength, amplitude, uye mafungu akamira paplasma achimutswa nesimba remafrequency akakwira, huwandu hwezvinhu zvinopindura hunoratidza chimiro chedenderedzwa chine kugoverwa kusingaenzaniswi.
3. Simba remurazvo rinoora kubva panzvimbo iri pakati, uye kuwanda kwezvinhu zvinopindura kunoita kuti pave nekupararira kwakasiyana-siyana.
Kuwanda kwekupisa uye reaction zvinhu zvinogadzirwa nekuora kwesimba riri pamusoro apa kunokurumidza kubuda kunze zvakatevedzana; saka, nzvimbo dzakasiyana dzemould dzinosangana nenzvimbo dzakasiyana dzereaction substance concentration kuti dzikure madhaimani films ane mamiriro akasiyana echimiro uye ukobvu hwakasiyana, zvichiita kuti dhaimani isabatane. (Non-homogeneous) vibration characteristics, dzakadai sehukobvu kana kuomarara zvinoratidza kupararira kusina kufanana, uye dhaimani thin film inobviswa kubva mumould kuti igadzire dhaimani vibration film. Mamiriro echimiro edhaimani materials anosanganisira micro-crystal (Micro-crystal), nano-crystal (Nano-crystal) nezvimwewo.
Zvichienderana nefirimu rinodedera redhaimani rakagadzirwa nechinhu ichi chitsva, kuomarara kwaro nehukobvu hwaro hazvina kufanana, uye kuomarara kwenzvimbo yepakati kwakakwira, kuomarara kwenzvimbo yemucheto kwakaderera, uye ukobvu hwenzvimbo yepakati hwakakura, uye ukobvu hwenzvimbo yemucheto hudiki. Hunhu hwekudengenyeka kwechikamu chimwe nechimwe hunokanganiswa nekuomarara kwacho uye Mhedzisiro yeukobvu ine ma frequency akasiyana echisikigo, kuitira kuti diaphragm yedhaimani ive nebandwidth yakakura.
