Inwebu yedayimani engcangcazelayo kunye nendlela yokuvelisa, igqithisa amandla angeyoyunifomu (efana nentambo yokuxhathisa i-thermal, iplasma, idangatye) evuyisa irhasi edityanisiweyo ngaphezulu komngundo, isebenzisa umgama phakathi komphezulu ogobileyo wokungunda kunye namandla angeyoyunifomu. evuyisa irhasi edityanisiweyo Iiyantlukwano zenza iziphumo ezahlukeneyo zokufudumeza.Xa izinto zedayimani zigqunywe kumphezulu wokungunda, ukukhula kwezinto zedayimani kwahlukile, ukuze ifilimu yedayimani yokungcangcazela ibe neempawu zokungcangcazela ezingezo-homogeneous, ukuze ifilimu yokungcangcazela yedayimani ibe nebhanwidth ebanzi yomsindo.
Xa ukhetha izinto eziphathekayo ze-diaphragm, iingqalelo eziphambili zilukhuni kunye neempawu zokudambisa.Ubunzima bumisela ubuninzi bendalo bezinto eziphathekayo, kunye nobuninzi bendalo bezinto ezinobunzima obuphezulu buphezulu kakhulu, kwaye ngokuphambene noko, ukuphindaphinda kwendalo kwezinto ezinobunzima obuphantsi buphantsi.Izixhobo ezineempawu ezintle zokuthomalalisa zinokwenza i-membrane engcangcazelayo ibe nempendulo egudileyo yokungcangcazela, yenza inqanaba loxinzelelo lwesandi kwi-membrane engcangcazelayo ligudileyo.
Izinto ngokwesiko eziqhelekileyo zokungcangcazela inwebu zibandakanya iphepha, izinto zeplastiki yepolymer, isinyithi (Yiba, Ti, Al), iiseramikhi, njl Iphepha kunye nemathiriyeli yepolymer zineempawu ezintle zokudambisa, kodwa ukuqina okungahambi kakuhle kunye nomonakalo olula, kunye nobulukhuni obuphantsi akwanelanga ukubenza. Elona xesha liphezulu lokusebenza lilinganiselwe.Nangona ifilimu eshukumayo yesinyithi inobunzima obungcono, iintsimbi ezinobunzima obuphezulu obufana neBe, Ti, njl njl. zibiza kakhulu kwaye kunzima ukuziqhuba.Izinto zeCeramic nazo zinengxaki yeenkqubo ze-sintering ezinzima.Ngenxa yeempawu ezigqwesileyo zomatshini kunye namandla edayimani, ifanelekile ukuveliswa kobunzima bokukhanya, i-diaphragms ephezulu, kwaye ingasetyenziselwa izithethi eziphakathi kunye ne-high-frequency.Isandi esifunwayo senziwa ngokungcangcazela rhoqo kwi-diaphragm.Ukuphakama kwe-vibration frequency ye-diaphragm, ngqongqo amandla omatshini kunye neemfuno zomgangatho we-diaphragm, kunye nokusetyenziswa kwezixhobo zedayimane ukwenza i-diaphragm inokufezekisa le njongo.
Ngokuqhelekileyo, i-membrane engcangcazelayo inomda ophezulu wokuphendula rhoqo.Nangona kunjalo, kungakhathaliseki ukuba i-membrane engcangcazelayo yenziwe ngedayimane okanye ezinye izinto, i-frequency yendalo inqunyelwe kuluhlu oluthile ngenxa yeempawu ezibonakalayo ezifanayo, ezikhawulela ukusebenza kwayo kwe-bandwidth.Iimpawu zokudambisa kunye nokuqina akukwazi ukutshintshwa ngokungqongqo, okukhawulela umgangatho wesandi kunye nokusebenza kwe-timbre.Ngoko ke, ukuba ufuna ukugubungela uluhlu oluqhelekileyo olwamkelekileyo kwindlebe yomntu, ngokuqhelekileyo kufuneka ubeke i-diaphragm ezininzi kunye ne-bandwidths eyahlukeneyo kunye nemida ephezulu ngexesha elifanayo ukufezekisa umphumo wesandi.Ke ngoko, kubugcisa bangaphambili, kukho itekhnoloji yokusebenzisa izixhobo ezahlukeneyo ukwenza i-membrane engcangcazelayo kumacandelo.Inxalenye ephakathi ye-membrane engcangcazelayo yenziwe ngezinto ezinobunzima obuphezulu, kunye nendandatho yangaphandle yenziwe ngezinto ezinobunzima obuphantsi.Emva koko ezi zimbini zidibeneyo ukuze zenze enye I-membrane engcangcazelayo inobunzima bezinto ezimbini ezahlukeneyo kunye nobukhulu ngexesha elifanayo, kwaye inokugubungela i-bandwidth enkulu.Nangona kunjalo, ubukhulu befilimu eshukumayo buhlala buncinci kakhulu, kwaye umsebenzi wokujoyina unzima.Ukuba kuya kusetyenziswa kwizinto zedayimane, iteknoloji yokudibanisa kunye ne-agent edibeneyo yingxaki enkulu kakhulu, ngoko akulula ukuyisebenzisa kwizinto zedayimane.
Ukuze kulungiswe ezi ngxaki zingasentla, ukuveliswa kwangoku kucebisa ifilimu engcangcazelayo yedayimani kunye nendlela yokuvelisa, enokutshintsha ubulukhuni, ubukhulu kunye neempawu zokuthambisa zemimandla eyahlukeneyo kwifilimu engcangcazelayo yedayimani, ukuze ibe neempawu zokungcangcazela ezingeyoyunifomu kwaye igubungela uluhlu olukhulu lwamaza..
Ngokwenwebu yedayimani engcangcazelayo kunye nendlela yokuvelisa edizwe kuyilo lwangoku, isikhunta esinomphezulu ogobileyo sinikezelwe, kwaye amandla angeyo-homogeneous (non-homogeneous) anika imincili irhasi engadityaniswanga idlula ngaphezulu komngundo ukuvelisa. ubushushu obuphezulu ukufudumeza ukungunda ukwenzela ukuba umphezulu wokungunda ubonise ukuhanjiswa kobushushu obungalinganiyo.
Umzekelo nge
1. I-thermal resistance wire yindawo esembindini (eyona ndawo iphezulu yamandla), kwaye ukuxinana kwento yokusabela kubonisa ukusasazwa kweringi engalinganiyo.
2. Ngenxa yeempembelelo ze-wavelength, i-amplitude, kunye namaza amileyo kwi-plasma echulumancisiweyo ngamandla aphezulu-frequency, ukuxinwa kwezinto ezisabelayo kubonisa imilo engqukuva kunye nokusabalalisa okungafaniyo.
3. Ilangatye lamandla libola ngaphandle ukusuka kwindawo esembindini, kwaye ukuxinana kwezinto ezisabelayo kubonisa ukusasazwa okungafaniyo.
Iqondo lobushushu kunye nempendulo yoxinzelelo lwento eyenziwe ngamandla angentla abola ngokukhawuleza ngaphandle ngokulandelelana;ke ngoko, izikhundla ezahlukeneyo zomphezulu wokungunda zinxibelelana nemimandla eyahlukeneyo yoxinaniso lwento yokusabela ukukhulisa iifilim zedayimani ezinesimo esahlukileyo sokwakheka kunye nobukhulu obahlukeneyo, okwenza imathiriyeli yedayimani ibe nokungafani.(ezingezo-homogeneous) iimpawu zokungcangcazela, ezinje ngokungqingqwa okanye ubulukhuni bukhoyo usasazo olungafaniyo, kwaye emva koko ifilimu yedayimane ebhityileyo iyasuswa kumngundo ukwenza ifilimu yedayimani yokungcangcazela.Amazwe okwakhiwa kwezixhobo zedayimani ziquka i-micro-crystal (i-Micro-crystal), i-nano-crystal (i-Nano-crystal) kunye nokunye.
Ngokutsho kwefilimu yedayimane eshukumayo eyenziwe yindalo yangoku, ubunzima bayo kunye nobukhulu bayo abufani, kwaye ubunzima bendawo ephakathi buphezulu, ubunzima bendawo yomgca buphantsi, kwaye ubukhulu bendawo ephakathi bukhulu, kwaye ubukhulu bendawo yomgca buncinci.Iimpawu ze-vibration zecandelo ngalinye zichaphazelekayo ngobunzima kwaye Umphumo wobunzima uneendlela ezahlukeneyo zendalo ngokulandelanayo, ukwenzela ukuba i-diaphragm yedayimane ingaba ne-bandwidth enkulu.
