Subwoofer uye mutauri hurongwa Frequency norudaviro

Pakutanga manonwe uye eighties wekupedzisira remakore, zvakanzi vaidavira kuti makuru vakurukuri ari mbiru, nani. The ano kusvika kune sangano iri sonification pakati accomodations siyanei kuparadzirwa Dolby VANOKOMBEREDZA maitiro pamwe yoga subwoofer zvishoma kuzununguswa chivimbo Zvakanyanya Kunaka Panguva Yepamuviri mutauri inzwi multiple munotaura asi mafeni zvakasiya chaizvo chaizvo.

Mubvunzo chii chinofanira kuva simba ari mukurukuri, nehanya Developers uye technologists kubva musi electromechanical transducers akapinda upenyu. Pane mumwe kupokana pakati zvinodiwa kuti diffuser. Kudivi rimwe, kuti yakaderera unhu playback, kuti bass siyana ive huru zvakakwana uye hombe rinobva coils, pamusoro "swinging bass" mashizha akawanda simba. Ukuwo, yakakwirira frequencies zvinoda kunonyanyisa nenyama oscillatory maitiro uye pasipasi inertia.

Pakupedzisira, Developers acoustic nenhumbi ndakauya musoro mhinduro iri mbiru papi pamwe kushanda woofers uye vanonzi "tweeter". Zvisinei, muchiitiko ichi nayo rinoonekwa "kukundikana" iri pakati chakarondedzera, asi dambudziko iri panobviswa nokuda kuwedzera mukurukuri rechitatu kushanda Range ichi.

Saka Frequency norudaviro dzichienderana pamusoro yose anzwike bhendi. The woofer inogona kushanda pasina mamwe filters, asi kuti kuderedza mutoro pamusoro payo uye achawedzera mukurumari, anopiwa ane inductance akatevedzana-hwakabatana, kwete transmissive svikiro uye makuru. The gudzanzwi pakati riri hakuperi kubva kuva kuti "vohveli" kune Bass, uye yokumusoro chiratidzo zvinoriumba. Kuti izvi zvidaro, maererano naro waisanganisira coils uye capacitor. Kana "tweeter", saka anogona kusvitsa chete arongera kubva boka anenge 3 kHz uye kumusoro, nokuti gudzanzwi uku ngaatevedzane capacitance iyi iripowo.

Modern bass gudzanzwi chinhu chisinganzwisisiki electromechanical mudziyo. Weboka diffuser iwayo guru. Kukutsigira kwenguva refu, zvinhu vanosungirwa kukurira kwakavharwa nenyama deformation uye nokudaro kuramba zvivako zvayo. Kazhinji, pamuuyo emitter chokuita rabha mhete diffuzoroderzhatelem semicircular chikamu.

Kurohwa ane millimeters shoma, inofanira kuva nzira yakajeka, zvimwe kunogumira coils vachava "overwritten" nechepakati magineti. Iye akapa kuvakira pesin inowanzopiwa wakaitwa nebwe bhainda akaiswa mushonga wokuuraya jira Perforated ane annular corrugation.

Woofer - a yepamusorosoro mudziyo pakurigadzira anoshandiswa ose kuchangobva mberi polymer kugadzirwa. The diffuser anofanira kuva yakaoma, ipapo nesimba coils achapiwa chinopfuudzwa munzvimbo yayo pamusoro anenge pakarepo, uye nyore kuwedzera unhu muduku zvichibvira nguva lag. Zvisinei, vakawanda kupfuura zvinodhura uye yepamusoro vakurukuri, oddly zvakakwana, pasinei nokufambira mberi kwezvigadzirwa zvemazuva ano, bepa rinoshandiswa sezvo mutauri wokutanga, iyo yakagadzirwa muna 1925 vokuAmerica zvibodzwa Rice uye kellogg.

The woofer wava chinokosha magadzirirwo upi yepamusoro mutauri hurongwa.
