Noneho ko uzi impamvu rukuruzi z'impeta zifite akamaro muri indangururamajwi, reka turebe neza uko zikora mu itsinda rya moteri. Ibi bizatuma byoroha kubona impamvu ubuziranenge n'ubudahinduka bigira ingaruka nziza ku bwiza bw'amajwi.

Uburyo Magnets z'impeta zikora imbere mu byuma bitanga amajwi n'amajwi

Niba wigeze gukata indangururamajwi, ushobora kuba warabonye rukuruzi ifite ishusho nk'iy'udupira inyuma. Iyo ni rukuruzi ifite ishusho nk'iy'impeta. Nubwo idasa cyane ubwayo, mu by'ukuri iba irimo guterura ibintu biremereye—mu buryo bw'ukuri—igihe cyose ijwi rivuye muri uwo mushoferi.

Ingufu zizunguruka ni zo mutima w’imiterere ya moteri muri indangururamajwi nyinshi zikoresha imbaraga. Akazi kazo ni ukurema imbaraga zizunguruka zihamye kandi zituje, aho ijwi rishobora gusunika. Utabikoze, nta kindi wageraho uretse guceceka - cyangwa se ikibi kurushaho, imbaraga nyinshi zihindagurika kandi zipfusha ubusa.

Dukurikije ibyo twabonye bikorana na OEMs z'amajwi, gukora neza magnet si uguhitamo amanota meza gusa ku rupapuro rw'ibanga. Ni uguhuza imyitwarire ya magnet n'uburyo indangururamajwi zizakoreshwa. Kandi niho imishinga myinshi inyura.

 

Gufata byihuse
- Ingufu zikora ingufu za rukuruzi zitwara ijwi
- Imiterere n'ubuziranenge bigira ingaruka ku buryo butaziguye ku ireme ry'amajwi
- Ingano, ingano, na magnetization bigomba guhuza n'ikoreshwa
- Gutumiza ibintu byinshi bisaba kugenzura neza ubuziranenge—nta bidasanzwe

 

Icyo Magnets z'impeta zikora mu by'ukuri mu cyuma gitanga umuvuduko

Reka tubirebe. Indangururamajwi ifite ibice bitatu by'ingenzi: agace k'umurambararo (cyangwa diaphragm), urukiramende rw'ijwi, n'urukiramende rw'imoteri. Urukiramende rw'imoteri niho uruziga rw'impeta rubera.

Kubaka Umurima wa Magnetic Uguma Ahantu Hakomeye

Iyo ishyizwe hagati y’icyuma cyo hejuru n’icyuma cyo inyuma, icyuma gikurura urusaku gikora icyuho gito, gishingiye ku ijwi. Aha hantu niho ingufu za electromagnetic ziyobora ingendo z’ikirangurura. Igikurura rusaku kigomba gutanga imbaraga za magnetic zizewe kandi zijyanye neza mu cyuho, nta guhindagurika cyangwa imikorere idahwitse.

Kwimura Ijwi, Kwimura Umwuka

Iyo koili y'ijwi imaze kwakira ikimenyetso cy'amajwi gikoresha amashanyarazi, ikora imbaraga za rukuruzi zihinduka kandi igakora nk'ingufu zigenzurwa. Iyi ngufu ikora ku ruziga rudahindagurika ruturuka kuri rukuruzi y'impeta, bigatuma koili y'ijwi n'agace gafatanye bihindagurika. Imiterere yo hejuru y'urusaku ikora amajwi menshi, mu gihe intera nini y'urugendo ikomeza igisubizo cya bass nke.

Uko imbaraga za rukuruzi zisukuye kandi zihamye, ni ko ijwi rikurikira neza ikimenyetso. Niyo mpamvu rukuruzi z'impeta zikundwa kurusha izindi miterere mu kintu icyo ari cyo cyose kuva kuri studio monitors kugeza kuri sisitemu z'amajwi z'imodoka. Imiterere yazo ishyigikira urwego rungana, bivuze ko injeniyeri adatekereza cyane ku bijyanye no gutunganya crossover.

 

Impamvu Magnets z'impeta zikomeza kugaragara mu bikoresho by'amajwi

Bafite umutwaro mu murima wabo

Twakuyemo isomo rikomeye ariko ry'ingirakamaro mu myaka yashize: rukuruzi isa neza ku mpapuro ishobora gutsindwa byoroshye mu bihe nyabyo. Nyuma y'amasaha menshi yo kuyikoresha mu kabati k'indangururamajwi gashyushye kandi karimo guhindagurika, imikorere yayo ishobora kugabanuka cyane.Ingufu za Neodymiumhamwe n’ubushyuhe bwinshi butuma imbaraga zabyo za rukuruzi ziguma zihamye, nubwo ijwi ritangira gushyuha. Uku guhagarara ni ingenzi cyane kurusha uko injeniyeri nyinshi zibibona. Iyo rukuruzi itakaje ingufu mu gihe cyo kuyikoresha, ubushobozi bw’indangururamajwi buragabanuka vuba, kandi ubwinshi bw’imyandikire ntibube bungana.

Bagufasha kubaka indangururamajwi nto kandi zivuga cyane

Ingufu za Neodymium ring magnets zirakomeye cyane ukurikije ingano yazo. Niyo mpamvu uzibona mu ndangururamajwi nto za Bluetooth, ecouteurs zo mu rwego rwo hejuru, n'utubari tw'amajwi duto. Ubona imbaraga za rukuruzi za rukuruzi nini cyane ya rukuruzi ya ferrite mu gice gito cy'umwanya. Ku bikoresho bitwarwa, ibyo birahindura ibintu.

Ariko hari aho bihurira. Amanota akomeye nka N52 arushaho kwangirika kandi arushaho kwangirika n'ubushyuhe. Hari igihe magneti nini gato ya N42 iba ari yo mahitamo meza—ihangana neza n'ubushyuhe, kandi ntabwo izacika iyo umuntu aguye indangururamajwi mu gihe cyo guteranya.

 

Kubona Ibisobanuro Bikwiye kuri Porogaramu z'Amajwi

Aha niho amabwiriza yihariye aba cyangwa apfa. Niba ushaka magneti z'impeta ku murongo mushya w'indangururamajwi, hari ibintu bitatu ugomba gufunga mbere yuko prototype ya mbere itangira.

Igipimo cya Magnet si Ingufu gusa

Buri wese yifuza umubare munini wa N. Ariko mu gukora amajwi mu buryo bufatika, twabonye N52 itera ibibazo byinshi kuruta uko ikemura. Irapfa. Ntikunda ubushyuhe. Kandi niba indangururamajwi yawe igiye mu muryango w'imodoka cyangwa mu kabati ka PA kari ku zuba, uba wibaza ibibazo.

Amanota y'ubushyuhe bwinshi nka N42SH cyangwa N40UH arahenze cyane, ariko arahagarara iyo ibintu bishyushye. Twagize umukiriya umwe ujya kuri N42SH nyuma y'uko itsinda ry'indangururamajwi za N52 rigarutse rifite umusaruro muke nyuma y'impeshyi y'ibikorwa byo hanze. Impinduka mu manota zarakemutse.

Ingano zigomba kuba zikomeye—zikomeye cyane

Icyuho aho ijwi rihagarara gipimirwa mu bice bya milimetero. Niba umurambararo w'imbere wa magnet yawe uhinduka na mm 0.1 mu gihe cyo gukora, uzagira ikibazo cyo kudahuza kw'amajwi kuva ku ndangururamajwi imwe kugeza ku yindi. Icyo ni ikibazo iyo ugerageza kugurisha amajwi ahuye cyangwa kubaka amajwi.

Dusuzuma ingero dukoresheje calipers. Ku bicuruzwa byinshi, dushyiraho uburyo bwo kugenzura buri kimwe kandi tugahakana ikintu cyose kidahuye n'ubworoherane twiyemeje. Niba umucuruzi abifata nk'ibidakenewe, komeza ushake.

Icyerekezo cy'ingufu za rukuruzi ntigishobora kuganirwaho

Ku ndangururamajwi, uruziga rw'impeta rugomba gushyirwaho magneti mu buryo bw'umurongo umwe—mu bunini, ntabwo ari mu bugari. Iyo magneti idahuje, imbaraga za magneti ntiziba hagati mu cyuho. Ijwi rizikora, guhindagurika kwazo bizazamuka, kandi imikorere yazo izagabanuka. Abakora neza bagerageza uburyo magneti zikoreshwa mbere yo kohereza.

 

Ibitekerezo ku bijyanye n'inganda ku bice by'amajwi

Iyo utumije ibihumbi by'udukuru tw'impeta kugira ngo ukoreshe indangururamajwi, ntuba uguze ibice gusa, ahubwo uba uguze uburyo bwo gukora ibintu buri gihe.

Kubaka-gucapa ni cyo kintu cy'ibanze

Dukoresha ibishushanyo by'ubuhanga bigaragaza:
- Umurambararo wo hanze, umurambararo w'imbere, n'ubugari hamwe n'ubushobozi bwo kwihanganira
- Ubwoko bw'igitambaro n'ubugari bwacyo (NiCuNi ku bikorwa byinshi by'amajwi, epoxy ku bidukikije bifite ubushuhe bwinshi)
- Icyerekezo cya magnetization n'imbaraga z'umurima ntarengwa
- Ibisabwa ku isuzuma ryo gukurura ku bibanza by'icyitegererezo

Iyo uruganda rukubajije impamvu ukeneye ko hagaragazwa uburebure bw'igitambaro, ntabwo rwakoze akazi kenshi k'amajwi. Twabonye kwangirika kwa nickel plating ku bikoresho byo guteranya, bigatuma habaho kwangirika nyuma y'amezi menshi. Bisobanure neza, bigerageze, urebe neza.

Kugira ngo umenye byinshi ku mahitamo y'ibikoresho n'uburyo bwo kubitunganya, reba urupapuro rwacu kurigukora magneti ya neodymium yihariye.Kandi niba upima imiterere y'impeta ugereranije na disiki ku mushoferi runaka, incamake yacu yarukuruzi za disiki muri sisitemu z'amajwiikubiyemo aho buri genamiterere ryumvikana.

Amasomo yo mu buzima busanzwe aturuka mu iduka

Kimwe mu byo nakomeje kuvuga: twari dufite umukiriya wacungaga umurongo w’indangururamajwi za PA zikoresha ingufu. Byose byageragejwe neza muri laboratwari. Nyuma y’amezi atandatu, ibikoresho byatangiye kugaruka bifite umuvuduko muke wa bass. Indangururamajwi zari zarakuweho igice.

Byaragaragaye ko ubushyuhe bw'imbere mu gihe cy'ibikorwa birebire byo hanze bwari bugeze kuri dogere selisiyusi 90 kuri sumaku. N42 isanzwe ntabwo yari yashyizwe ku rutonde rw'ibyo. Twahinduye tujya ku rwego rwo hejuru, twongera imbaraga mu gishushanyo mbonera, hanyuma itsinda rikurikiraho rimara imyaka ibiri nta ngaruka na imwe ijyanye na sumaku.

Ihame ry'inkuru: ikizamini mu bidukikije, atari muri laboratwari gusa. Amadorari amagana make yakoreshejwe mu igerageza ry'ibishushanyo mbonera byo mu isi nyayo ashobora kugufasha kumererwa nabi mu gihe kizaza.

Ikindi: guhuza imigozi. Ntabwo bifitanye isano itaziguye na magnets z'impeta, ariko niba ibicuruzwa byawe by'amajwi birimo ibikoresho bya magnets—grilles zishobora gukurwaho, ibikoresho byo gushyiramo—uburyo bwo gufatanya ni ingenzi. Twabonye kole zinanirwa mu bushyuhe, ibyuma bicika mu gihe cy'ubukonje, kandi vis zigakurwaho bitewe n'ihindagurika. Ku bikoresho byo mu iduka cyangwa ibikoresho bya PA bitwarwa, imigozi ya rubber overmold ifite ibifunga bya mechanical ikunda kuramba kurusha ibindi byose.

 

Ibibazo Bikunze Kubazwa

Ese nshobora gukoresha magnet imwe y'impeta kuri woofers na tweeters?
Muri rusange oya. Woofers zikenera moteri zikomeye zifite icyuho kinini cya rukuruzi kugira ngo zikore ingendo ndende. Tweeters zikoresha imbaraga ntoya kandi zibanda cyane ku rukuruzi. Ingano n'urwego bya rukuruzi akenshi biratandukanye.
