Isandi sobungcali sidla ngokubhekisa kwisandi esisetyenziswa kwiindawo zokuzonwabisa zobungcali ezifana neeholo zomdaniso, amagumbi e-KTV, iithiyetha, amagumbi eenkomfa kunye namabala emidlalo. Izithethi zobungcali zinobuntununtunu obuphezulu, uxinzelelo lwesandi oluphezulu, amandla amahle, kunye namandla amakhulu okwamkela. Ngoko ke, zeziphi izinto ezisetyenziswa kwizixhobo zezithethi zobungcali?

Ulwakhiwo lwezithethi ezingoochwephesha: izixhobo zomsindo zobungcali ziquka umxube wemonitha; umxube we-amplifier yamandla; umxube ophathwayo; umbane okhulisa amandla; imakrofoni enamandla; imakrofoni ye-condenser; imakrofoni engenazingcingo; isithethi; isithethi semonitha; isithethi se-amplifier yamandla; i-subwoofer ephantsi kakhulu; i-Equalizer; i-Reverberator; i-Effector; i-Delayer; i-Compressor; i-Limiter; i-Crossover; i-Noise Gate; i-CD Player; i-Recording Deck; i-Video Disc Player; i-Projector; i-Tuner; i-Song Player; ii-headphones, njl. Izixhobo ezininzi zenziwe.

Kukho iintlobo ezininzi zezithethi: ngokweendlela zazo zokuguqula amandla, zingahlulwa zibe ngombane, ngombane, ngombane, ngombane, nge-piezoelectric, ngedijithali, njl.njl.; ngokwesakhiwo se-diaphragm, zingahlulwa zibe ziikhowuni ezi-single, ngeekhowuni ezidibeneyo, ngeempondo ezidibeneyo, kwaye ziyafana. Kukho iintlobo ezininzi zeeshafts; ngokwe-diaphragm, ingahlulwa ekuqaleni ibe luhlobo lwekhowuni, uhlobo lwedome, uhlobo oluthe tyaba, uhlobo lwebhanti, njl.njl.; ngokwe-replay frequency, ingahlulwa ibe zizithethi ezi-high frequency, eziphakathi, ezi-low frequency kunye nezithethi zebhendi epheleleyo; ngokwe-magnetic circuit. Le ndlela ingahlulwa ibe luhlobo lwangaphandle lwe-magnetic, uhlobo lwangaphakathi lwe-magnetic, uhlobo lwe-dual magnetic circuit kunye nohlobo olukhuselweyo; ngokwendalo ye-magnetic circuit, ingahlulwa ibe ziimagnethi ze-ferrite, iimagnethi ze-neodymium boron, kunye nezithethi ze-AlNiCo magnet; ngokwedatha ye-diaphragm. Yahlulwe yaba zizithethi zephepha nezingezizo iikhowuni, njl.njl.

Ikhabhinethi isetyenziselwa ukususa i-acoustic short circuit yeyunithi yesithethi, ukuthintela i-acoustic resonance yayo, ukwandisa isicwangciso sayo sempendulo ye-frequency, kunye nokunciphisa ukuphazamiseka. Ulwakhiwo lwemilo yekhabhinethi yesithethi lwahlulwe ngohlobo lweshelufu yeencwadi kunye nohlobo lomgangatho, kunye nohlobo oluthe nkqo kunye nohlobo oluthe tye. Ulwakhiwo lwangaphakathi lwebhokisi luneendlela ezahlukeneyo ezifana ne-closed, inverted, band-pass, empty paper cone, labyrinth, symmetrical drive, kunye nohlobo lwe-horn. Ezona zisetyenziswa kakhulu zi-closed, inverted kunye ne-band-pass.

I-Crossover inomahluko phakathi kwe-power frequency divider kunye ne-electronic frequency divider. Imisebenzi ephambili yazo zombini kukusika i-frequency band, i-amplitude-frequency characteristic kunye ne-phase-frequency characteristic correction, i-impedance compensation kunye ne-attenuation. I-power divider, eyaziwa ngokuba yi-passive post divider, yahlula i-frequency emva kwe-power amplifier. Iquka ikakhulu izinto ezingasebenziyo ezifana nee-inductors, ii-resistors, ii-capacitors kunye nezinye izinto ezingasebenziyo ukwenza inethiwekhi yesihluzo, kwaye ithumele imiqondiso yesandi yebhendi nganye ye-frequency kwizithethi zebhendi ye-frequency ehambelanayo ukuze iphindaphindwe. Iimpawu zayo zixabiso eliphantsi, isakhiwo esilula, esifanelekileyo kubadlali abangengabo, kodwa iingxaki zayo kukulahlekelwa okukhulu kokufakwa, amandla aphantsi, kunye neempawu ezimbi ze-transient.

Umahluko phakathi kwesandi sobuchwephesha kunye nesandi sasekhaya: Hlalutya ngokufutshane umahluko phakathi kwesandi sobuchwephesha kunye nesandi sasekhaya: isandi sobuchwephesha ngokubanzi sibhekisa kwiindawo zokuzonwabisa zobungcali ezifana neeholo zomdaniso, amagumbi e-KTV, iithiyetha, amagumbi eenkomfa, kunye namabala emidlalo. Iindawo ezahlukeneyo, iimfuno ezahlukeneyo zokuhamba kunye nokungashukumi, kunye nezinto ezahlukeneyo ezifana nobukhulu bendawo, zixhotyiswe ngezisombululo zenkqubo yesandi kwiindawo ezahlukeneyo. Isandi sobuchwephesha ngokubanzi sinobuntununtunu obuphezulu, uxinzelelo lwesandi sokudlala oluphezulu, amandla amahle, kunye namandla amakhulu okwamkela. Xa kuthelekiswa nesandi sasekhaya, umgangatho waso wesandi unzima kwaye inkangeleko yaso ayinzima kakhulu. Nangona kunjalo, ukusebenza kwezithethi zesikrini kusondele kakhulu kunomsindo wasekhaya, kwaye inkangeleko yazo ngokubanzi intle kwaye intle, ngoko olu hlobo lwesithethi sesikrini lusetyenziswa rhoqo kwiinkqubo zesandi ze-Hi-Fi zasekhaya.

Izixhobo zesandi zasekhaya:

1. Umthombo wesandi: Imvelaphi yentshukumo. Imithombo yesandi eqhelekileyo kwinkqubo yesandi yasekhaya ibandakanya iirekhoda zekhasethi, abadlali beCD, abadlali beLD, abadlali beVCD kunye nabadlali beDVD.

2. Izixhobo zokwandisa: Ukuze kusetyenziswe izithethi ezinamandla aphezulu ukuvelisa isandi, isiphumo sesiginali esivela kumthombo wesandi ngokubanzi kufuneka sandiswe amandla. Izixhobo zokwandisa eziqhelekileyo ngoku zii-AV amplifiers, ezidla ngokuba zii-transistor amplifiers, kodwa ngoku abanye abantu abathanda isandi nabo bayayithanda i-tube expanders.

3. Izixhobo zokuvelisa isandi: Isithethi, esiza kuchaphazela ngqo umgangatho wesandi.

4. Umgca woqhagamshelo: kuquka umgca woqhagamshelo ukusuka kumthombo wesandi ukuya kwi-amplifier yamandla kunye nomgca woqhagamshelo ukusuka kwi-amplifier yamandla ukuya kwisithethi.

Umahluko kumgangatho wesandi:

Umgangatho wesandi sezithethi ubaluleke kakhulu. Umgangatho wesandi umisela impembelelo yomculo emzimbeni nasengqondweni yabantu. Abantu bamandulo bahle kakhulu: ukulawula ilizwe ngesimilo kwaye umculo kukusebenzisa umgangatho wesandi olungileyo kunye nomculo olungileyo ukwakha ubuntu babantu nokwenza umzimba, ingqondo, nomphefumlo wabantu ufikelele kwimeko yoxolelwaniso, umzimba nengqondo yomntu ziya kuba nophuculo lwempilo kunye. Ke ngoko, umgangatho wesandi ulingana nempilo yomzimba.

Isandi esisemgangathweni sinika abantu imvakalelo yovelwano. Olu luvo luchukumiso oluvela nzulu emphefumlweni, oluvela kwinxalenye yokwenene yabantu. Luvakala ngathi luthando lukamama ngabantwana bakhe, lufumisa izinto. Luthule, kodwa lukhona. Isandi esinye kuphela esizisa umothuko emphefumlweni.

Injongo ephambili yenkqubo yesandi yasekhaya kukufumana umsebenzi wokumamela onomdla, njengomsebenzi wesandi sethiyetha ekhaya. Kodwa usapho lwahlukile kwithiyetha, ngoko ke lufuna ii-acoustics ezahlukeneyo kwiintlobo ezahlukeneyo zesandi. Lufuna umculo we-pop, umculo weklasikhi, umculo olula, njl.njl. ukuze lukwazi ukubuyisela izixhobo zomculo ezahlukeneyo ngokufanelekileyo, kwaye lufuna uvakalelo lokuba khona kunye neziphumo zesandi xa ubukela iimuvi.
