Cov kev vibrations no raug xa mus rau lub cartridge uas lub stylus txuas nrog. Cov duab ntawm cov tsis sib xws yog xws li qhov kev vibrations ntawm rab koob rov ua dua lub teeb liab acoustic kaw rau ntawm disc thaum nws kaw.

Ib me ntsis ntawm keeb kwm

Nyob rau hauv lub qub turntables, rab koob yog ua los ntawm hlau, tom qab ntawd cov koob tau hauv av los ntawm sapphire. Lub ntsiab lus ntawm rab koob yog hauv av kom lub vojvoog ntawm nws curvature yog peb txhiab ntawm ib nti (0,003 ″, piv txwv li 76 µm) rau cov laus (ebonite, thiaj li hu ua "standard zawj" daim hlau, ua si ntawm 78 rpm) lossis 0,001 ″ (25 µm) rau cov ntaub ntawv tshiab (vinyl) cov ntaub ntawv hu ua "zoo-groove" cov ntaub ntawv.

Txog rau thaum xyoo 70s, muaj turntables nyob rau hauv uas cartridges nrog ob hom koob raug ntsia, uas ua rau nws muaj peev xwm mus ua si tag nrho cov ntaub ntawv muaj nyob rau hauv lub lag luam thiab khaws cia nyob rau hauv archives. Cov koob rau kev tsim cov ntaub ntawv zoo-groove feem ntau yog cim nrog ntsuab, thiab nrog cov qauv-groove sawv daws yuav - liab.

Tsis tas li ntawd, qhov tso cai siab ntawm rab koob ntawm lub phaj zoo yog qis dua li ntawm tus qauv-groove phaj, tsis pub ntau tshaj 5 grams tau pom zoo, uas tseem ua rau kom ceev ceev ntawm daim hlau (cov txheej txheem niaj hnub ntsuas lub caj npab nrog rau kev tso cai. ntxig tso cai ua haujlwm nrog lub siab ntawm 10 mN, piv txwv li kwv yees li 1 gram).

Nrog rau kev qhia txog cov ntaub ntawv stereophonic ntawm cov ntaub ntawv gramophone, cov kev xav tau rau cov koob thiab gramophone cartridges tau nce, muaj cov koob tshwm sim uas tsis yog cov duab puag ncig, thiab cov koob pob zeb diamond kuj tau siv los hloov cov sapphire. Tam sim no, qhov kev txiav zoo tshaj plaws ntawm koob gramophone yog quadraphonic (van den Hul) thiab elliptical txiav.

Kev faib tawm ntawm cov khoom ntxig

• piezoelectric (lawv tsuas yog qhov tseem ceeb ntawm keeb kwm vim qhov nqaim bandwidth, lawv kuj xav tau ntau lub siab ntawm lub phaj, ua rau nws hnav sai dua)

• electromagnetic – ib tug hlau nplaum txav mus rau lub kauj (MM)

• magnetoelectric – lub kauj yog txav mus rau cov hlau nplaum (MC)

• electrostatic (muaj peev xwm tsim),

• kho qhov muag-laser

Qhov twg ntxig rau xaiv?

Thaum xaiv ib qho ntxig, peb yuav tsum xub txheeb xyuas seb cov khoom siv yuav siv li cas. Seb rau DJing lossis mloog cov ntaub ntawv hauv tsev.
