Momwe mungasankhire gitala la electro-acoustic?

Nthawi zambiri mumafunika phokoso lamayimbidwe. Zoyenera kuchita kuti mukhale ndi gitala lamayimbidwe nthawi imodzi ndikulikulitsa pamakonsati popanda vuto lililonse? Ndi zophweka. Njira yothetsera vutoli ndi magitala a electro-acoustic, mwachitsanzo, magitala acoustic okhala ndi zida zamagetsi zomwe zimatumiza chizindikiro ku amplifier. Chifukwa cha izi, mawonekedwe amayimbidwe amasungidwa, ndipo kuti timve ngakhale pa konsati yokweza, ndikwanira kulumikiza gitala ndi amplifier (kapena ngakhale mawonekedwe omvera, powermixer kapena chosakanizira).

Kumanga gitala

Mbali yofunika kwambiri ya gitala la electro-acoustic ndikumanga kwake. Pali zinthu zambiri zomwe zimapita kumayendedwe amawu onse.

Tiyeni tione kaye kukula kwa thupi. Matupi akuluakulu amaika mphamvu zambiri pamafupipafupi otsika ndikupangitsa kuti chidacho chikhale chokweza kwambiri. Matupi ang'onoang'ono, kumbali ina, amapangitsa kuti phokoso likhale lotalika (kuchirikiza kwambiri), komanso kumapangitsanso kuthamanga kwa gitala.

Muyeneranso kusankha ngati mukufuna kudula. Zimapereka mwayi wabwinoko wamanote apamwamba pama frets omaliza. Komabe, magitala opanda indentation amakhala ndi timbre yakuya ndipo amamveka kwambiri akamayimba popanda kugwiritsa ntchito zamagetsi.

Magitala a electro-acoustic amatha kukhala matabwa olimba kapena laminated. Kusuntha kwamitengo yolimba kumamveka bwino, kotero kuti gitala imamveka bwino. Komabe, magitala a laminate ndi otsika mtengo. Kugwirizana kwakukulu pakati pa resonance yabwino ndi mtengo ndi magitala acoustic okhala ndi nkhuni zolimba "pamwamba", koma ndi laminated kumbuyo ndi mbali, chifukwa "pamwamba" imakhudza kwambiri phokoso.

Mitundu yamatabwa

Ndikoyenera kuyang'anitsitsa mitundu yosiyanasiyana ya nkhuni chifukwa imakhudza kwambiri phokoso la gitala. Ndikambirana zomwe zimagwiritsidwa ntchito nthawi zambiri m'matupi a magitala a electro-acoustic.

Spruce

Kuuma ndi kupepuka kwa nkhuniyi kumapangitsa kuti phokoso liwonekere kuchokera kwa izo "zachindunji". Phokoso limakhalanso lomveka ngakhale pamene zingwe zathyoledwa mwamphamvu.

ananyamula

Mahogany amapereka phokoso lakuya, laphokoso, kutsindika makamaka zotsika komanso zapakati. Imawonjezeranso ma harmonics ambiri apamwamba pamawu oyambira.

Rosewood

Rosewood imapanga ma harmonics ambiri apamwamba. Ili ndi mapeto omveka kwambiri pansi, zomwe zimapangitsa kuti phokoso likhale lakuda koma lolemera.

Mapulo

Maple, kumbali ina, ali ndi chizindikiro cholimba kwambiri. Maenje ake ndi ovuta kwambiri. Mitengo ya mapulo imakhala ndi zotsatira zabwino pakuthandizira gitala.

Mkungudza

Cedar imakhudzidwa kwambiri pakusewera kofewa, ndichifukwa chake oimba magitala am'manja amawakonda kwambiri. Ili ndi phokoso lozungulira.

Mitengo ya chala chala imakhala ndi zotsatira zochepa pa phokoso. Mitundu yosiyanasiyana ya nkhuni zala zala makamaka zimakhudza momwe chala chala chala chimamvera ndi zala. Komabe, iyi ndi nkhani yovuta kwambiri.

zamagetsi

Njira yonyamulira phokoso kuchokera ku gitala imadalira magetsi omwe amagwiritsidwa ntchito mmenemo.

Piezoelectric transducers (piezo mwachidule) ndi otchuka kwambiri. Kugwiritsiridwa ntchito kwawo ndi njira yodziwika kwambiri yowonjezera phokoso la magitala a electro-acoustic. Chifukwa cha izi, phokoso la magitala a electro-acoustic okhala ndi piezo pickups ndizomwe timayembekezera. Makhalidwe awo ndi "quacking", zomwe ndi zabwino kwa ena, ndizovuta kwa ena. Iwo ali ndi kuukira mwamsanga. Siziwoneka kuchokera kunja kwa gitala, chifukwa nthawi zambiri zimayikidwa pansi pa chishalo cha mlatho. Nthawi zina amatha kukhala pamwamba pa gitala. Kenako, komabe, amataya mawonekedwe awo a "quack" ndipo amakhala okhudzidwa kwambiri ndi mayankho kuposa piezo yomwe imayikidwa pansi pa chishalo cha mlatho.

Maginito converters m'mawonekedwe, amafanana ndi omwe amagwiritsidwa ntchito popanga magitala amagetsi. Iwo ali ndi pang'onopang'ono ndi mofatsa kuukira ndi nthawi yaitali. Amatumiza ma frequency otsika bwino kwambiri. Sakhala okhudzidwa kwambiri ndi mayankho. Komabe, amakonda kukongoletsa kwambiri phokosolo ndi mawonekedwe awoawo.

Nthawi zambiri ma transducers, kuphatikiza pa piezoelectric kapena maginito, akugwirabe ntchito. Nthawi zambiri amafuna batire ya 9V. Chifukwa cha iwo, timapeza mwayi wokonza phokoso la gitala chifukwa cha zingwe zomwe zimayikidwa nthawi zambiri pambali ya thupi. Muthanso kupeza chochunira chomangidwa mu gitala, chomwe chimakulolani kuyimba bwino gitala ngakhale pamakhala phokoso chifukwa cha kukhalapo kwa ma pickups.

Kukambitsirana

Kusankha koyenera kwa gitala kudzatithandiza kukwaniritsa mawu omwe tikufuna. Zambiri zimakhudza phokoso, koma zimapangitsa magitala kukhala osiyana. Kumvetsetsa bwino zigawo zonse kudzakuthandizani kugula gitala ndi makhalidwe a sonic omwe mumalota.
