Kufambisa iron element; finite element analysis; zvikamu zvemukati; kugadzirwa kwegomba; acoustic performance.
Mumakore achangopfuura, nekukurumidza kukura kweindastiri ye earphone, vanoda mimhanzi vane zvakakwirira uye zvepamusoro zvinodikanwa zvemhando yekurira.maearphone , saka maearphone ari nyore anochinja haachakwanisa kuzadzisa zvinodiwa. Semagumo,kumhanya-wireless-earbuds-bluetooth -for-sports-earbuds-bluetooth-5-0-product/”>mahedhifoni ane coil inofamba uye simbi inofambisa yakawedzera kupinda mumunda wekuona kwevanoda mimhanzi. Iyo gobvu yepakati-bass yeinofamba coil unit uye yakajeka uye yakajeka treble yeinofamba simbi unit zvishoma nezvishoma yave musanganiswa wakakwana.
Iyo inofambisa coil unit yatokura izvozvi, asi vanhu vazhinji vanoziva zvishoma nezve inofamba simbi unit. Naizvozvo, bepa rino rinosuma chimiro chemukati uye musimboti wekushanda weiyo inofamba simbi unit zvakadzama, uye kuburikidza neinogumira ongororo yechinhu, ita kuti iwe unzwisise zvakadzama magadzirirwo akatarisana neiyo inofamba simbi unit. Kuburikidza nechinyorwa ichi, kwete chete vanotanga vanogona kunzwisisa inofamba simbi unit, asiwo mugadziri weinofamba simbi unit anogona kupfupisa kutenderera kwedhizaini uye kuderedza mutengo wekugadzira kuburikidza neinogumira chinhu simulation.
1 Chimiro chemukati chekufamba kwesimbi unit
Mufananidzo 1 ndiyo yemukati chimiro chekufamba kwesimbi unit. Inogona kuonekwa kubva pamufananidzo kuti zvikamu zvemukati ndezvi: chivharo chepamusoro, chivharo chepasi, PCB, diaphragm, inzwi coil, square iron, magnet, armature uye kutyaira tsvimbo. Pane buri reruzha padivi pechivharo chepamusoro, uye nzvimbo yegomba rekurira inoshanduka nenzvimbo chaiyo yekuburitsa ruzha mushure mekuiswa munzeve. Kazhinji, chivharo chepamusoro chinogadzirwa nesimbi; chivharo chepasi chinoshandiswa kugadzirisa sikweya simbi, uye zvinhu zvakazara isimbi. Yakanamwa nechifunhiro chokumusoro; pane majoini maviri ekutengesa paPCB ekutsvaira tambo yehedhifoni; mupendero we diaphragm unowanzo gadzirwa neTPU zvinhu zvine elasticity yakanaka, uye yepakati inogadzirwa nesimbi zvinhu; zvinhu zveizwi coil iwaya yemhangura, kuitira kuti ivandudze frequency, inogona zvakare kuputirwa neSilver wire; sikweya iron zvinhu zvinowanzoita nickel-iron alloy; magineti zvinhu kazhinji Alnico; armature uye tsvimbo yekutyaira inowanzova nickel-iron alloy.
2 Nheyo yekushanda yesimbi inofamba
Nheyo yekushanda yeyuniti yesimbi inofamba: kana izwi coil risina chiratidzo chekuisa, iyo shrapnel inochengetedza mamiriro akaenzana mune magnetic field. Kana chiratidzo chemagetsi chikatumirwa kune coil yezwi, iyo armature ichave ine magineti uye ichizununguka kumusoro nekudzika musimba remagineti, nekudaro ichityaira tsvimbo yekutyaira nemudonzvo rekutyaira. Iyo diaphragm inodedera kuita ruzha. Iyo U-shaped armature yemuchina wesimbi inofambisa yakafanana neyakagadzirwa lever, imwe mugumo inogadziriswa pakona yesimbi, uye imwe mugumo inomiswa uye yakabatanidzwa kune inotyaira tsvimbo. Naizvozvo, kufamba kudiki kwechitsiko musimba remagineti kuchawedzera kumagumo, uye ipapo chiratidzo chakasimudzirwa chinozoendeswa kune diaphragm, ndicho chikonzero chekunzwa kwepamusoro kweiyo inofamba iron unit.
3 Finite element yekuongorora yekufamba simbi unit
Sezvo mukana mukuru weiyo inofamba simbi unit iri yakakwira frequency, pepa iri rinotora treble inofamba simbi unit semuenzaniso wekuongorora. Nekuda kwehukuru hudiki hweiyo inofamba simbi unit, ine zvakakwirira zvinodiwa pakurongeka kwezvinhu. Kuti unyatsoongorora uye kunyatso ongorora pesvedzero yezvikamu zvikuru zvesimbi inofamba uye mhango pane acoustic performance, kuburikidza neinogumira chinhu chekuongorora, nekupinda iyo 3D modhi yeinofamba iron unit, iyo yekupinza zvinhu zvivakwa, ita modal. kuongorora, uye kutevedzera frequency mhinduro curve. Mufananidzo 2 ndiyo yekufananidza modhi yeinofambisa iron unit.
