Ungasarudza sei electro-acoustic gitare?

Kazhinji unoda acoustic sound. Chii chaunofanira kuita kuti uve negitare acoustic panguva imwe chete uye kuikudza mumakonzati pasina matambudziko? Zviri nyore. Mhinduro ndeye electro-acoustic guitars, kureva magitare acoustic ane akavakirwa-mukati magetsi anoendesa chiratidzo kune amplifier. Nekuda kweizvi, maacoustic maitiro anochengetedzwa, uye kuti isu tinzwike kunyangwe pakonzati ine ruzha, zvakakwana kubatanidza gitare kune amplifier (kana kunyange kune odhiyo interface, powermixer kana musanganiswa).

Kuvaka gitare

Chinhu chakakosha chegitare re electro-acoustic ndiko kuvakwa kwayo. Pane zvinhu zvakawanda zvinopinda muhuwandu hwezwi.

Ngatitarisei kukura kwemuviri kutanga. Iyo miviri mikuru inoisa yakanyanya kudzvanywa pane yakaderera frequency uye inoita kuti chiridzwa chiwedzere ruzha. Mitumbi midiki, kune rumwe rutivi, inoita kuti ruzha rugare kwenguva refu (yakanyanya kusimudzira), uye zvakare inovandudza kukurumidza kupindura kwegitare.

Iwe unofanirwawo kusarudza kana iwe uchida kucheka. Inopa kuwana kuri nani kune epamusoro manotsi pane ekupedzisira frets. Zvakadaro, magitare asina indentation ane timbre yakadzama uye anokwidza kana achiridzwa pasina kushandisa zvemagetsi.

Electro-acoustic magitare anogona kuva matanda akasimba kana laminated. Kutamiswa kwehuni kwakasimba kunonzwika zviri nani, saka gitare rinorira zvirinani. Nekudaro, magitare elaminate akachipa. Kubvumirana kukuru pakati pezvakanaka resonance uye mutengo magitare acoustic ane huni yakasimba "pamusoro", asi ine laminated kumashure uye mativi, nokuti "pamusoro" ine simba guru pane inzwi.

Mhando dzehuni

Zvakakosha kunyatsotarisa mhando dzakasiyana dzehuni sezvo dzine simba guru pakunzwika kwegitare. Ini ndichakurukura izvo zvinonyanya kushandiswa mumitumbi ye electro-acoustic guitars.

Spruce

Kuoma uye kureruka kwehuni iyi kunoita kuti inzwi rionekwe kubva mairi "zvakananga". Ruzha runochengetawo kujeka kwarwo kunyangwe tambo dzakadzurwa zvine simba.

Mahogany

Mahogany inopa yakadzika, punchy ruzha, kusimbisa kunyanya yakaderera asiwo yepakati ma frequency. Iyo inowedzerawo akawanda epamusoro maharmonics kune yekutanga ruzha.

Rosewood

Rosewood inogadzira akawanda epamusoro harmonics. Iyo ine yakanyatso kutaurwa pazasi magumo, izvo zvinokonzeresa kune rima rose asi rakapfuma ruzha.

Maple

Mepu, kune rumwe rutivi, ine yakasimba kwazvo yakanyorwa pamusoro. Makomba ake akaoma zvikuru. Maple huni ane mhedzisiro yakanaka pakutsigira kwegitare.

Cedar

Cedar inonyanya kunzwisiswa nekutamba kwakapfava, ndosaka magitare emunwe kunyanya kuifarira. Iine ruzha rwakaurungana.

Huni hwechigunwe hune zvishoma zvinokanganisa inzwi. Mhando dzakasiyana dzehuni dzeminwe dzinonyanya kukanganisa manzwire anoita zvigunwe neminwe. Zvisinei, iyi inyaya ine musoro.

Electronics

Nzira yekutora inzwi kubva pagitare inobva pamagetsi anoshandiswa mairi.

Piezoelectric transducers (piezo for short) dzinofarirwa zvikuru. Kushandisa kwavo ndiyo nzira yakajairika yekusimudzira ruzha rwemagetsi-acoustic guitars. Nekuda kweizvi, ruzha rwe electro-acoustic magitare ane piezo pickups ndizvo chaizvo zvatinotarisira kuti zviite. Hunhu kwavari "quacking", inova mukana kune vamwe, uye kukanganisa kune vamwe. Vane kukurumidza kurwisa. Izvo hazvionekwe kubva kunze kwegitare, sezvo ivo vachiwanzoiswa pasi pebhiriji chigaro. Dzimwe nguva vanogona kunge vari pamusoro pegitare. Zvino, zvakadaro, vanorasikirwa nehunhu hwavo hwe "quack" uye vanotapukirwa nemhinduro kupfuura piezo yakaiswa pasi pechigaro chebhiriji.

Magnetic converters pakuonekwa, vakafanana neanoshandiswa mumagitare emagetsi. Vane kurwisa kunononoka uye kunyoro uye kwenguva refu. Ivo vanofambisa yakaderera frequency zvakanyanya. Havana kunyanya kukanganiswa nemhinduro. Nekudaro, ivo vanowanzo wedzera-ruvara ruzha nehunhu hwavo.

Kazhinji ma transducers, kunze kwekuve piezoelectric kana magnetic, achiri kushanda. Vanowanzoda bhatiri re9V. Kutenda kwavari, tinowana mukana wekugadzirisa ruzha rwegitare nekuda kwemapfundo anoiswa kazhinji padivi remuviri. Iwe unogona zvakare kuwana tuner yakavakirwa mugitare, iyo inokutendera kuti unyatso kuridza gitare kunyangwe munzvimbo dzine ruzha nekuda kwekuvapo kwepikicha.

Summation

Sarudzo yakanaka yegitare ichaita kuti tiwane ruzha rwatinoda. Zvizhinji zvinokanganisa ruzha, asi zvinoita kuti magitare asiyane kubva kune mumwe nemumwe. Kunzwisisa kwakaringana kwezvinhu zvese zvinokutendera iwe kutenga gitare rine sonic maitiro aunorota nezvawo.
