Mus txog qhov no, peb've tau piav qhia qhov sib txawv ntawm kev ua tau zoo ntawm qib nkag, tsim tsis zoo thiab hwm lub tsheb suab amplifiers. Peb vam koj'tau pom cov ntaub ntawv no, thiab tam sim no nws's lub sij hawm peb tau saib ze ntawm lub tsheb hais lus. Tsis muaj lub tsheb lub suab yog qhov tseem ceeb tshaj li cov neeg hais lus rau kev tsim cov suab paj nruag nrog qhov tseeb thiab meej.
Cov kab lus no yuav txheeb xyuas qhov impedance, zaus teb, tso zis muaj peev xwm thiab distortion yam ntxwv ntawm txawv tsheb suab hais lus. Lub hom phiaj yog muab rau cov neeg ntawm koj uas xav hloov kho qhov tseeb thiab kev ua tau zoo ntawm koj lub kaw lus kom muaj kev sib raug zoo ntawm cov qauv tsim, kev qhia tshwj xeeb thiab, thaum kawg, kev ua tau zoo.

Lub khob fiber ntau thiab roj hmab puag ncig ntawm no OEM Honda Civic hais lus.
Factory-Installed Honda Civic Speaker
Kuv muaj ib lub rooj hais lus los ntawm Honda Civic rau peb thawj qhov kev kawm. Qhov no yog woofer (tsis muaj tweeter) nrog lub khob hliav qab zoo ntawm 125.5 millimeters ntsuas los ntawm nruab nrab ntawm ib puag ncig ntawm ib sab ntawm tus neeg tsav tsheb mus rau qhov chaw ntawm sab nraud. Lub khob hliav qab yog tsim los ntawm cov woven daj fiber ntau uas yuav yog iav los yog aramid muaj pes tsawg leeg. Lub kaus mom plua plav yog tsim los ntawm cov ntaub mos mos tab sis tsis tshua muaj zog. Tus neeg hais lus muaj cov roj hmab puag ncig, uas kav ntev dua li ua npuas ncauj.
Mechanically, tus hais lus muaj ib tug me me-inch ca kab laug sab kab laug sab khi rau ib tug 1-inch suab coil qub. Nyob ntawd's tsis muaj qhov cua txias rau tom qab ntawm cov hlau nplaum los yog qhov cua hauv qab kab laug sab mounting ledge. Lub pob tawb yog tsim los ntawm kev txhaj tshuaj molded, iav fiber ntau-reinforced polycarbonate thiab muaj rau qhov sib sib zog nqus cov lus. Raws li ib txwm muaj rau tus neeg hais lus OEM, lub mounting flange muaj xws li ib tug built-in spacer nrog ib tug integrated gasket uas yuav coj tus hais lus tawm ze ntawm lub grille nyob rau hauv lub sab hauv lub qhov rooj trim vaj huam sib luag. Zuag qhia tag nrho, ib sab ntawm lub suab me me thiab tsis muaj cov thev naus laus zis txias, tus qauv tsim tsis muaj dab tsi tseem ceeb los yws txog.

Puas muaj ib yam dab tsi uas peb tuaj yeem pom nyob rau hauv cov nqe lus ntawm kev ua tau zoo los ntawm ntsuas Thiele / Me tsis? Thawj qhov peb pom yog tias tus neeg tsav tsheb muaj tag nrho Q (Qts) siab ntawm 0.69. Qhov no yuav ntxiv me ntsis resonant pob nyob rau hauv cov zis nyob rau hauv qis midbass cheeb tsam. Nws's yuav yog ib qho zoo tsim kev lag luam tawm rau tus neeg hais lus tsim los siv yam tsis muaj subwoofer, vim nws yuav ntxiv qhov kov ntawm qhov sov so rau lub suab. Txawm li cas los xij, hauv cov ntsiab lus tseeb, qhov no yuav yog me ntsis ntawm qhov tsis xav tau distortion. Thaum kawg, qhov kev kwv yees ua tau zoo yog qhov siab ntawm 89.04 dB SPL thaum tsav nrog 1 watt ntawm lub zog thiab ntsuas ntawm 1 meter. Qhov no kuj yog ib txwm zoo rau tus neeg hais lus OEM raws li lawv ua lag luam cov zis tsawg zaus rau cov zis ntau ntxiv ntawm ntau zaus. Lub ~10-gram txav pawg txhawb qhov kev xav no.
Cia's saib seb BassBox Pro enclosure simulation software kwv yees tus neeg tsav tsheb no yuav ua li cas hauv peb 3-cubic-foot test enclosures. Kuv xaiv qhov ntim no raws li nws's feem ntau loj txaus kom muaj kev cuam tshuam tsawg heev rau tus neeg tsav tsheb's kev ua tau zoo thiab yuav tsum simulate li cas tus neeg hais lus yuav coj tus cwj pwm nyob rau hauv ib lub qhov rooj los yog rear parcel txee.

Cov lus teb tsawg zaus ntawm peb Honda qhov rooj hais lus nyob rau hauv daim ntawv thov baffle infinite.
Raws li koj tuaj yeem pom los ntawm daim duab saum toj no, qhov no yog ntau tus neeg tsav tsheb nruab nrab dua li woofer. Kuv kwv yees ntawm 30-watt fais fab tuav raws li qhov me me ntawm lub suab coil thiab tsis muaj cua txias. Hais txog kev kwv yees, tus tsav tsheb muaj -3 dB zaus ntawm 98 hertz thiab yuav tau txais txiaj ntsig zoo los ntawm kev siv nrog lub subwoofer.

Lub impedance cheb ntawm Honda Civic's 6.5-inch qhov rooj hais lus.
Peb tuaj yeem pom lwm yam hauv daim duab no. Ib yam dab tsi tau ua rau pom qhov ncov resonant ntawm li 700 txog 800 Hz, thiab muaj cov wiggles ntxiv hauv cov lus teb ntawm 2.4, 3.7 thiab 5.2 kHz. Cov no yuav tshwm sim los ntawm lub khob hliav qab, plua plav hau lossis ib puag ncig resonating. Peb'Nws yuav pom yog tias ib qho ntawm cov no txhais ua qhov sib txawv ntawm qhov ntsuas qhov ntsuas acoustic.

Nrog tus neeg tsav tsheb thauj khoom rau hauv kuv 3- cubic-foot test enclosure, kuv muab tso rau hauv pem teb ntawm kuv lub chaw kuaj mob. Lub microphone los ntawm Clio Pocket yog 1 yard saum toj kawg nkaus ntawm lub khob hliav qab, qhov twg nws ua tau raws li ib puag ncig. Peb'yuav siv txoj haujlwm no rau txhua tus hais lus mus tom ntej. Peb'yuav pib qhov kev xeem los ntawm kev ntsuas cov lus teb zaus ntawm kev nce qib tsav. Thaum tsis muaj tus qauv tshwj xeeb, peb'll clone dab tsi Vance Dickason siv nyob rau hauv nws cov kev ntsuam xyuas transducer hauv Voice Coil magazine nrog 0.3, 1, 3, 6, 10 thiab 15 volts. Nws's tsis ntseeg tias tus neeg tsav tsheb yuav nyob twj ywm hauv cov zis ntawm 10- thiab 15-volt theem raws li cov nqi sib npaug rau 25 thiab 56 watts ntawm lub zog rau hauv ib qho 4-ohm load. Kuv yuav ntxiv ib qho 2-volt ntsuas uas sib npaug rau 1 watt rau hauv ib qho 4-ohm load.
Ua ntej peb nkag mus rau hauv kev tsom xam ntawm tus neeg hais lus, peb yuav tsum nkag siab ob peb yam txog kev ntsuas. Ua ntej, cov ntaub ntawv hauv qab 30 Hz tuaj yeem tsis quav ntsej. Tsis muaj qhov tso zis ntawm 100 dB SPL ntawm 10 Hz. Qhov thib ob, qhov poob ntawm 130 Hz yog qhov kev xav hauv chav. Nws tuaj yeem tsis quav ntsej thiab. Peb paub tias qhov no yog qhov kev tshem tawm acoustic vim tias tsis muaj qhov poob lossis qhov siab tshaj plaws hauv qhov impedance lossis distortion nkhaus. Thov txim, kuv tsis ua't tshwm sim kom muaj anechoic chamber ntawm kuv pov tseg. Lub sijhawm no, kuv'tseem yuav muas daim pib!
