Txoj Cai Tswj Kev Tsav Tsheb

Kev ua haujlwm ntawm tus tsav tsheb kauj vab yog nyob ntawm kev sib cuam tshuam ntawm cov hlau nplaum ruaj khov thiab lub suab coil nyob hauv tus tsav tsheb. Thaum lub suab coil txuas nrog lub zog hluav taws xob nrog kev hloov pauv tsis tu ncua tam sim no, nws tsim qhov induced magnetic teb nyob ib ncig ntawm lub kauj, hloov nws cov kev taw qhia ib ntus. Qhov no induced magnetic teb interacts nrog lub magnetic teb uas tsim los ntawm cov hlau nplaum mus tas li, ua rau repulsion los yog attraction rog uas ua rau lub suab coil mus oscillate nce thiab nqis.

Raws li cov kev taw qhia tam sim no tsis tu ncua hloov, lub suab coil reciprocates nce thiab nqis raws li qhov zaus hloov pauv ntawm qhov tam sim no. Tib lub sijhawm, lub diaphragm txuas nrog lub suab coil kuj txav mus los sib xws, hloov pauv huab cua nyob ib puag ncig los tsim kev hloov pauv hauv huab cua ceev, tom qab tsim suab. Qhov zaus ntawm lub suab generated yog ncaj qha proportional rau qhov ceev ntawm tam sim no kev taw qhia hloov. Qhov no mechanism elucidates kev ua hauj lwm ntawm lub txav coil tsav tsheb.

3 Feem ntau Hom Neeg Hais Lus Tsav Tsheb

Horn Speakers

Muaj tseeb rau lawv lub npe, horn loudspeakers feature qhib, funnel-puab qauv reminiscent ntawm lub trumpet. Ntau tus tuaj yeem paub qhov tsim qauv no los ntawm vintage phonographs, tseem hu ua gramophones. Nyob rau hauv thaum ntxov iterations, ib tug flared horn ua hauj lwm ob lub hom phiaj ntawm amplifying suab generated los ntawm ib tug vibrating diaphragm. Qhov tseem ceeb, lub horn hloov vibrations ntawm lub diaphragm mus rau saum huab cua thaum amplifying lawv los txhim kho ntim.

Cone Speakers

Cone hais lus siv cov geometry paub txog lub khob hliav qab, feem ntau ntsib hauv tsev kawm ntawv cov chav kawm geometry. Qhov kev tsim no muaj nyob rau hauv cov ntaub ntawv nrov tshaj plaws ntawm kev tsim tsav tsheb. Ib tug neeg tsav tsheb lub khob hliav qab muaj xws li lub khob hliav qab daim nyias nyias nrog lub hauv paus plua plav hau, ib feem uas tsis muaj kev cuam tshuam rau lub suab zoo. Suab reproduction cia siab rau lub membrane txoj haujlwm. Txuas nrog lub suab coil, daim nyias nyias txav mus rau qhov chaw sib nqus uas tsim los ntawm cov hluav taws xob tam sim no ntws los ntawm lub kauj hauv qhov chaw sib nqus. Qhov kev rov qab mus rau tom ntej no, hu ua excursion, distinguishes cone hais lus raws li qhov zoo tshaj plaws ntawm cov neeg tsav tsheb sib tham, yog li vim li cas hom tsav tsheb no qee zaum hu ua "dynamic loudspeaker."

Dome Speakers

Zoo ib yam li cov neeg hais lus horn thiab lub khob hliav qab, lub npe zoo piav qhia txog cov neeg hais lus dome. Feem ntau concave thiab me dua lub cone hais lus, qhov kev tsim no muaj qhov zoo ntawm kev muab lub kaum sab xis dav rau sab saud, yog li txo qhov kev xav ntawm ntau zaus.

Multimedia Speaker TsavSizes

Cov tsav tsheb sib txawv ntawm qhov loj thiab muaj nuj nqi, feem ntau categorized rau hauv peb hom raws li cov zaus lawv tsim tawm:
