2. Capacitive horn

Lub tshuab raj capacitive siv lub hauv paus ntsiab lus ntawm hluav taws xob teb los tsim lub suab, thiab nws cov diaphragm muab tso rau ntawm ob lub electrodes.Thaum tam sim no dhau mus, lub diaphragm vibrates nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb los tsim suab.Hom neeg hais lus no feem ntau muaj cov lus teb zoo tshaj plaws thiab cov ncauj lus kom ntxaws, thiab tau siv dav hauv cov tshuab suab nrov.

3. Magnetostrictive horn

Magnetostrictive horn siv cov yam ntxwv ntawm cov khoom siv magnetostrictive los tsim suab los ntawm kev siv cov hlau nplaum kom ua rau me ntsis deformation.Hom horn no feem ntau siv rau hauv cov ntawv thov tshwj xeeb, xws li kev sib txuas lus hauv qab dej acoustic thiab kev kho mob ultrasound.

Kev faib cov neeg hais lus

1. Kev faib tawm los ntawm cov khoom siv zaus

-Bass speaker: Ib tus neeg hais lus tshwj xeeb tsim los rau cov ntses bass thaj tsam sib sib zog nqus, feem ntau yog lub luag haujlwm rau kev tsim cov suab nrov hauv thaj tsam ntawm 20Hz txog 200Hz.

-Tus neeg hais lus nruab nrab: lub luag haujlwm rau kev tsim cov suab paj nruag nyob hauv thaj tsam ntawm 200Hz txog 2kHz.

-High pitched speaker: lub luag hauj lwm rau reproducing suab signals nyob rau hauv lub ntau yam ntawm 2kHz mus rau 20kHz, feem ntau yog siv los tsim cov suab nrov.

2. Kev faib tawm los ntawm lub hom phiaj

-Tus neeg hais lus hauv tsev: tsim los rau lub tshuab suab hauv tsev, feem ntau nrhiav kev ua haujlwm zoo ntawm lub suab thiab kev paub suab zoo.

-Txoj kev hais lus: siv nyob rau hauv cov sijhawm ua haujlwm xws li theem suab, kaw lub studio saib xyuas, thiab lub rooj sib tham hauv chav nthuav dav, feem ntau muaj lub zog thiab lub suab zoo.

-Car horn: Tshwj xeeb tsim rau lub tsheb suab tshuab, nws feem ntau yuav tsum tau xav txog tej yam xws li qhov chaw txwv thiab qhov chaw acoustic hauv lub tsheb.

3. Kev faib tawm los ntawm Txoj Kev Tsav Tsheb

-Unit Speaker: Siv ib lub tshuab tsav tsheb ib zaug los tsim cov suab nrov tag nrho.

-Multi unit speaker: Siv ntau lub tshuab tsav tsheb los qhia cov haujlwm ua haujlwm ntawm cov zaus sib txawv, xws li ob, peb, lossis ntau qhov kev tsim channel.

Raws li ib qho ntawm cov khoom tseem ceeb ntawm lub tshuab suab, cov neeg hais lus muaj ntau txoj kev xaiv ntawm lub suab zoo, kev pab cuam band zaus, lub zog tso tawm, thiab cov xwm txheej ntawm daim ntawv thov.Kev nkag siab ntau hom thiab kev faib tawm ntawm cov neeg hais lus tuaj yeem pab cov neeg siv xaiv cov khoom siv suab zoo dua uas haum rau lawv cov kev xav tau, yog li tau txais kev paub suab zoo dua.Nrog rau kev nce qib txuas ntxiv thiab kev tsim kho tshiab ntawm thev naus laus zis, kev txhim kho ntawm cov neeg hais lus tseem yuav ua rau kev txhim kho thiab kev vam meej ntawm lub suab.
