Mene ne impedance na belun kunne

Impedance belun kunne - wannan shi ne su jure ƙofar. Dogara a kan shi, da yawa fasaha da kuma aiki halaye na su.

Idan low impedance na belun kunne (25 ohms ko kasa), da suka bukatar ƙasa da makamashi don samar da wani high quality-sauti. Wadannan belun kunne suna da kyau dace domin yin amfani da na'urorin kamar music 'yan wasa, wayoyin hannu da sauran šaukuwa na'urorin.

Kuma idan belun kunne impedance ne 25 ohms more, su na bukatar karin makamashi don wani babban matakin fitarwa. Wannan juriya kare su daga yiwu lalacewar ta wurin overloads. Wadannan belun kunne za a iya amfani da mai fadi da kewayon audiotehnicheskih na'urorin. Alal misali, wadannan sun hada da amfani ga dj-saka alama model, maras muhimmanci juriya wanda shi ne game da 25-70 ohms.

Idan headphone impedance ne low, suka zama mafi saukin kamuwa zuwa lalacewa a lokacin da yin amfani da wani high-ikon amplifiers. Idan ka, misali, gama belun kunne da low impedance ga dj-illolin saitin da zai yi amfani da shi don ta cike iya aiki, kana da su, mai yiwuwa fashewa.

Saboda haka, abin da yake cikin ganiya impedance? Belun kunne a yi amfani domin proslushavaniya audio player ko wani šaukuwa kwamfyutar, ya kamata fi dacewa da juriya na game 16-20 ohms da kuma ji na ƙwarai daga akalla 100 DB / MW. Idan na'urarka gana da Turai ma'aunansa na matsakaicin ƙarfi, shi ne mafi kyau ga zabi belun kunne da wani impedance na 16 ohms, tun da wadannan na'urorin iyakar ikon ne har yanzu kasa da a wasu.

Yawanci, da shawarar maras impedance belun kunne nuna a cikin takardun da na'urar.

Yana da muhimmanci a yi la'akari da impedance na belun kunne, kamar yadda duk model da aiki tare da daban-daban yawa na wutar lantarki da kuma juriya. Kowane headphone model musamman lasafta da calibrated saduwa da takamaiman kaya girma. Wannan ba kawai tabbatar da aminci da yin amfani da fasahar, amma kuma prolongs ta lifespan.

Tun da farko, a cikin 60-80 shekaru, sau da yawa amfani high impedance belun kunne, tun da makamashi fitarwa na'urar da cewa lokaci ya sosai high. Da zarar fara amfani resistors, ragewan da fitarwa ƙarfin lantarki. A shekarar 1996, shi ya kafa misali a kan headphone impedance - 120 Ohm. Wannan ya na da wani tasiri a kan samar da ci gaba na model high impedance, amma a lokaci guda sun hana ta kara ci gaba da cikin wasu kwatance. A shekara ta 2009, da m tallace-tallace na iPod, sakamakon kayan aiki da low juriya ya sami high shahararsa. Saboda haka, ci gaban belun kunne da ƙananan impedance, samu wani sabon impetus.

Saboda haka, impedance na - daya daga cikin, idan ba mafi, amma yana da muhimmanci har yanzu halaye na belun kunne. Mun zabi your model kamata cika da audio kayan aiki, kana amfani, domin iyakar ingancin sauti da kuma tabbatar da barga al'ada aiki. Saboda haka, ya kamata ka kula da lokacin da sayen wani headphone impedance kuma zaɓi mafi dace model su hana m lalacewa da kuma tabarbarewar da ingancin aiki.
