Kune anenge anenge ari mukurukuri kana sarudzo ye headphones iwe unogona kutenga, uchawana tsanangudzo yeimpedance inowanikwa muna ohms (inofananidzwa se Ω). Asi kuvhara kana kusanganisira zvinyorwa zvemagetsi hazviwanzo kutsanangurira chinonzi impedance kana kuti nei ichikosha!
Nenzira yakanaka, imhedheni yakanaka sedombo guru'n'roll guru. Kuedza kunzwisisa zvose pamusoro pazvo kunogona kuva kwakaoma, asi mumwe haafaniri kunzwisisa zvose pamusoro payo kuti "uwane" iyo. Ichokwadi, pfungwa yekusava nemhuka ndiyo yakanyanya nyore kunzwisisa. Saka verenga paunowana kuti chii chaunoda kuziva kunze kwekunzwa sokuti iwe uri kutora chikoro chekudzidza-level paMIT.

Paunenge uchitaura nezvezvinhu zvakadai sematts uye magetsi uye simba , vazhinji vanyori vanoteerera vanoshandisa kuenzanisa kwemvura inoyerera kuburikidza nepombi. Sei? Nokuti iyo inofananidzira zvikuru iyo vanhu vanogona kuona uye kurondedzera kune!
Funga nezvemukurukuri sepombi. Funga nezveshoko rehurukuro (kana, kana uchida, mimhanzi) semvura inoyerera nepombi. Iyo yakakura pombi, nyore nyore mvura inogona kuyerera kuburikidza nayo. Mabomba makuru anogonawo kubata mamwe akawanda emvura inoyerera. Saka mutauri ane mweya wakadzika wakafanana nepombi huru; iyo inowedzera zviratidzo zvemagetsi kuburikidza uye inobvumira kuti iyerere nyore nyore.
Izvi zvinokurudzira zvinogona kuonekwa sekuenzaniswa kuunza 100 watts ku 8 ohms impedance, kana zvichida 150 kana 200 watts ku 4 ohms impedance. Iyo yakaderera imhedheni, nyore nyore magetsi (chiratidzo / mimhanzi) inoyerera kuburikidza nemukurukuri.
Saka izvi zvinoreva here kuti munhu anofanira kutenga mutauri ane impedance yakadzika? Kwete zvachose, nokuti akawanda emagetsi haasati agadzirirwa kushanda ne 4-ohm speakers. Funga kumashure pombi iyo inotakura mvura. Iwe unogona kuisa pipe yakakura mukati, asi inongotakura mvura yakawanda kana iwe une pombi yakasimba zvokuti inogona kugovera zvose zvinowedzera kubuda kwemvura.
Kuderera Kunokwana Kunoreva Kukuru Kwemhando Here?
Tora zvese chero hurukuro yakagadzirwa nhasi, itaurire kusvika kune imwe yakagadzirisa yakaitwa nhasi, uye iwe uchawana zvinopfuura zvakakwana muimba yako yekugara. Saka chii chakanaka, ichiti, 4-ohm mutauriri kana 8-ohm mutauriri? Hapana, zvirokwazvo, kunze kweumwe chete; Dzimwe nguva dzakaderera dzinoratidza kuwanda kwekugadzirisa zvakanaka majiniya pavakagadzira mukurukuri.
Chokutanga, chimiro chiduku. Mhedziso yemukurukuri inoshanduka sezvo inzwi rikwira uye richidzika mumatomu (kana kuti kazhinji). Semuenzaniso, pa 41 Hz (chinyorwa chakaderera pane bhesiti yakagadzirwa pasi), kusagadzikana kwemukurukuri kunogona kuva 10 ohms. Asi pa2,000 Hz (kupinda mukati repamusoro ye violin), impedance inogona kuva 3 ohms chete. Kana kuti inogona kushandurwa. Mhedzisiro yekusununguka yakaonekwa pahurukuro inongova yakawandisa yakawanda. Nzira iyo imhedheni yevatauriri vatatu vakasiyana inochinja nekuremekedza kuwanda kwezwi kunogona kuonekwa kubva pane chati iri pamusoro pechinyorwa chino.
Vamwe vevanonyanya kutaura vakurukuri vanongorati vanoda kunyange kunze kwemhedzisiro yevatauri kuti vanzwire zvakanyanya muhutano wose. Kungofanana nemunhu anokwanisa kuvhara chidimbu chehuni kuti abvise mapeji akakwirira ezviyo, injini yekukurukurirana ingashandisa magetsi ekugadzirisa nzvimbo dzepamusoro. Ichi ndicho chikonzero 4-ohm hurukuro inowanikwa mukukwira kwepamusoro-soro, asi inowanikwa mumasikirwo emashamba-mashoma.
Unogona Here Kuita Sangano Rako?
Paunosarudza 4-ohm hurukuro, iva nechokwadi chokuti amplifier kana mutori anogona kugona. Munhu angaziva sei? Dzimwe nguva hazvisi pachena. Asi kana chigadziridziro / chigadziri chinogadzirisa chiziviso chemasimba mukati ma8 ne4 ohms, iwe wakachengeteka. Zvikamu zvakawanda zvakasiyana-siyana (kureva,, pasina preamp in preamp kana tuner) inogona kutora 4-ohm speakers, zvichida chero ipi zvayo ye $ 1,300-uye-up A / V receiver .
Ndinenge ndichizeza, kunyange zvakadaro, kuti ndibatanidze 4-ohm kutaura ne $ 399 A / V receiver kana $ 150 stereo receiver. Inogona kunge yakanaka pamhepo yakadzika, asi inokonzera uye iyo pombi (amplifier) ingave isina simba rekupa pipe iyo yakakura (mukurukuri). Nyaya yakanakisisa, iyo mutevedzeri ichazvivharira pakarepo. Chiitiko chakaipisisa, iwe uchave uchipisa vaparidzi nekukurumidza kupfuura mutyairi weNASCAR anotakura injini.
Kutaura nezvemotokari, imwe nharo yekupedzisira: Mumoto audio, 4-ohm hurukuro inowanzo. Ndiyo nokuti motokari dzemitambo inotambaira pa12 volts DC pane 120 volts AC. A 4-ohm impedance inobvumira vatauriri vemotokari kuti vatore simba rakawanda kubva kumhepo yakadzika motopi audio. Asi usanetseka: Car audio amps yakagadzirirwa kushandiswa nevatauriri vasingatauri. Saka shingaira uye ufare! Asi ndapota, kwete munharaunda yangu.
