Kuwedzera kune vakurukuri vakanaka nokuti unhu bass kubereka, zvinokosha kuti zvakarurama ngaaverenge Vhoriyamu bhokisi mutauri maitiro uye zivei nezvehukorokodzwa kwayo mukugadzira. Homemade subwoofer chinofanira Zvakanyanya Kunaka Panguva Yepamuviri kukura bhokisi. Lovemore ino mumotokari kana subwoofer musha-yakagadzirirwa musha, muviri wakanaka - anokosha zvinoriumba inokanganisa kurira yepamusoro.

Ngatiyeukei kuti ichi inzwi zvose. chinozunguzirwa ichi. nzeve dzedu abate oscillations vane kakawanda muna zvinobva makumi kakawanda vanenge 20 zviuru Hertz (zvinogara pa wechipiri). Range iri kuonekwa ruzha, chaizvoizvo zviri zvishoma vakwanise. Chii isu hamunzwi nemhaka yakaderera zvikuru kakawanda - ndiko infrasound, uye yakakwirira kakawanda, uye isu hatisi anzwike - Ultrasound (kunzwa mhuka ake, dzakadai imbwa). Sound mafungu kuparadzira chete mumamiriro ezvinhu pamwe arambe achirema yakakwana. We kurira, nekuti tiri mumamiriro ezvinhu akadaro (mhepo).

The subwoofer reproduces chaizvo yakaderera frequencies kusvikira zana shoma Hertz. A kurira chinozunguzirwa akasikwa kubudikidza kwebasa diffuser Ndege (tikaisa diaphragm mutauri). Bato kwayo zvaitambidzwa mumhepo, uye ruzha sokuti tiri kunzwa. Mugumisiro chinhu chakafanana nokushanda pombi.

The chikuru basa the subwoofer yakakomberedzwa - kuwana zvakanakisisa inzwi. Mutauri pasina bhokisi haakwanisi, nokuti kwaita yepamusoro inzwi chinozunguzirwa tinoda chimwe chete danho kwayo, uye mutauri paruzhinji kunotipa chete maviri: akanaka uye kunaka (kumberi uye neshure divi diffuser membranes). Zvakaratidza vanonzi acoustic pfupi vematunhu kusingafadzi chaizvo kune nzeve. Kuparadzana mumwe inzwi kubva neimwe Pasika uye ndipiyona bhokisi mutauri.

Homemade subs ane zvakasiyana-siyana zvakagadzirwa. Vanhuwo zvikuru - mumwe mutauri akatarisa panze, sezvo iri kwakajairika mbiru, asi pane zvakawanda akaoma namano.

Sezvaunoziva, kuti zviparadzanise mutsindo kutotanga (sezvo pedyo mumwe wavo mukati subwoofer), zvinoda mumwe Rigidity guru muviri pachayo asingagari kwokupa vibrations mudenga. Naizvozvo, kunaka zvinhu inoita basa rinokosha. Pane zviri simba, zvakasimba, nani pamusana.

Yeuka kuti yakaipisisa nezvechisarudzo chipi subwoofer - zvakafanana, ichibata kugadzira. Kazhinji, mukurukuri ari haachatauri kubva pakati. Uyewo haana varumbidzwa mukaravhani subwoofer ari muchimiro kuutio, mapato vanofanira dzinosiyana kukura. Izvi zvose zvinoitwa kudzivisa resonance.

Homemade subwoofer vanofanira womukati vhoriyamu yakakwana. Kana chisipo, ipapo low-kakawanda ruzha iri zvinooneka simba nokuda kufurirwa simba mukati bhokisi, izvo vakasikwa basa membrane. Kana uchida kuva subwoofer vhoriyamu duku musha-yakaitwa, ipapo unofanira kutora woofer ine dhayamita duku, nokuti zvavakabvumirana Vhoriyamu bhokisi kunoenderana kukura kwayo cone.

Tafura rinodonongodza inokurudzirwa miganhu.

Asi zviri nani kuti kubvunza mapepa kuti simba renyu.
