Hifi-urwego 2.0 stereo Bluetooth yububiko bwa digitifike yububiko bwa TPA3116 50WX2 disikuru yerekana amajwi hamwe na filteri

Impanuro: Gusa iyo amajwi yinjiye arahagije kandi gutanga voltage / amashanyarazi birahagije hashobora kubaho imbaraga zihagije zo gusohora. Amashanyarazi atangwa ni menshi, imbaraga zigereranijwe zizaba nini, kandi ihembe rifite impedance zitandukanye zizagira ingufu zitandukanye. Mugihe cya voltage ihagije nubu, umubare munini wamahembe ohm, ntoya ugereranije nimbaraga zijwi, nyamuneka witondere!

Umuvuduko w'amashanyarazi: 12V ------ 8 ohm uvuga / 12W (umuyoboro wibumoso) + 12W (umuyoboro wiburyo), 4 Ohm uvuga / 20W + 20W
15V ----- 8 EUR / 18 + 18W, 4 EUR / irenze 30 + 30W
19V ------ 8 EUR / 32 + 32W, 4 EUR / irenze 45 + 45W
24V ------ 8 EUR / 38 + 38W, 4 EUR / irenga 55 + 55W
AUX yinjiza amajwi + Bluetooth 2-muri-1 urwego rwa HIFI hamwe na filteri 50Wx2 Bluetooth ya power power amplifier board

Akayunguruzo
Itondere! Ubushyuhe bwo gushyushya hamwe na 3M kole bigomba gukenera kuri chip ubwayo, reba ishusho yerekana ibisobanuro, uko bishyushye niko bigenda bifata neza nubushyuhe bwiza bwumuriro. Inyandiko y'urubanza igomba guteranya urubanza ubwayo, kandi verisiyo y'urubanza izana na screwdriver.
Iki gicuruzwa cyuzuyemo ibikoresho, cyane cyane imikorere ihanitse, igiciro kinini, byumwihariko kumuziki wa HIFI kugirango utange ingufu zongerewe imbaraga.
TPA3116D2 nicyiciro cya D power amplifier IC yatangijwe nisosiyete ya TI, hamwe nibipimo byerekana cyane. Inshuro ya modulation irashobora kugera kuri 1.2MHZ, kandi imbaraga nyinshi zisohoka zigoreka ziri munsi ya 0.1%.
Hamwe na AUX na Bluetooth uburyo bubiri bwamajwi yinjiza uburyo, bubiri murimwe;
Potentiometero kugirango ihindure amajwi, hamwe na switch, byoroshye kugenzura amajwi, ibereye cyane abavuga DIY.
Hamwe na filteri inductance, amajwi arazengurutse kandi arasobanutse.
Umuringa DC uhuza, uruzitiro rwuruzitiro, uhangane numuyoboro munini, nta bushyuhe, nta kwangiza insinga, insinga nziza, ntabwo byoroshye kumuzingo mugufi.
Umugozi wumutwe wa DC urashobora guhuzwa nimbaraga zo kwinjiza ibicuruzwa, nubwo waba udafite adaptate ya DC cyangwa bateri, birashobora guhuzwa byoroshye.
5.0 verisiyo ya Bluetooth, uburyo bwiza bwo kohereza, intera ndende.
Icyitonderwa kugirango ukoreshwe: Imbaraga zihinduranya ku kibaho nizishobora guhagarara, kandi imashini iri mumashanyarazi make nyuma yo kuzimya. Kuzimya burundu amashanyarazi cyangwa niba idakoreshejwe igihe kinini, icyuma cya DC kumashini kirashobora gucomeka.

Igisubizo kubibazo:

1.Ni gute wahitamo amashanyarazi?

Amashanyarazi yubuyobozi arakomeye. Iyo hejuru ya voltage, nini nini, hamwe nimbaraga zihagije zo gusohora, niba ufite 12V 1A gusa, urashobora kuzana disikuru ya 3-4. Niba ufite 19V 5A cyangwa irenga, ntakibazo na santimetero 8-10, kandi amashanyarazi agomba guhabwa agaciro gakomeye. Niba voltage iri hasi cyane, amplification yijwi iroroshye gutera kugoreka amajwi, niba ikigezweho ari gito cyane kugirango uzane disikuru izakurura voltage hasi, akazi ntasanzwe cyangwa amajwi meza ni mabi.

Basabwe gukoresha amashanyarazi 18V19V24V, amashanyarazi hejuru ya 3A. Niba ufite 9V12V cyangwa 1A 2A itanga amashanyarazi, irashobora kandi gukoreshwa ariko imbaraga ni nto, witondere amajwi ntarengwa mugihe ukoresheje bishobora kugoreka amajwi.

2. Nigute ushobora guhitamo umushikirizansiguro?

Ubusanzwe amahembe akoreshwa ni 8 ohm, ntashobora gutandukanya polarite nziza nibibi, ingaruka nimwe, 4 ohm yamahembe nayo irashobora gukoreshwa. Niba imbaraga zamahembe yawe ari nto, zishobora kuba hagati ya 10W-30W nazo zirashobora gukoreshwa, voltage yo gutanga ni nto kugirango wirinde cyane nyuma yo gutwika ihembe, nko guhitamo amashanyarazi munsi ya 15V. Niba uri ihembe rya 50W-200w, ntugahangayikishwe nikibazo cyo gutwika amahembe, urashobora guhitamo amashanyarazi 12-24V, hejuru ya voltage yatoranijwe, hanyuma niko amajwi asohoka cyangwa imbaraga.

3. Nigute ushobora guhitamo Bluetooth cyangwa AUX uburyo bwo kwinjiza amajwi?

Imbaraga ku kibaho cyongerera imbaraga imbaraga, huza disikuru, hindura urumuri rwerekana amajwi yubururu bwerekana ubururu, fungura terefone Igenamiterere - Bluetooth - shakisha "BT-WUZHI", hanyuma ukande guhuza, nyuma yo guhuza neza, hazabaho ding dong prompt tone, muriki gihe kuburyo bwa Bluetooth, urashobora gucuranga umuziki, imbaraga zikurikira zizahita zisubira kuri terefone.

Niba ushaka gukoresha amajwi ya AUX, urashobora guhagarika umurongo wa Bluetooth, hazabaho kandi ijwi ryihuta, ucomeka mumashanyarazi kugirango ucurange umuziki. MU buryo bwa AUX (LINE IN), Bluetooth ihita ihinduka muburyo bwa Bluetooth.

4. Ijwi rito ni ryiza, nyuma yijwi rimaze kwiyongera, hari phenomenon yijwi ryijimye?
Ijwi ryagoretse, nyamuneka uhindure imbaraga adapt hamwe nurwego rwo hejuru rwa voltage.

5. Ijwi rito ni ryiza, nyuma yijwi rimaze kwiyongera, hari phenomenon yijwi ryatinze?
Imbaraga zinjiza ntizihagije, amashanyarazi ubwayo rimwe na rimwe amashanyarazi arinda, nyamuneka gusimbuza amashanyarazi akomeye; Cyangwa imbaraga nini cyane, ikibaho cyongerera ingufu ubushyuhe burashyuha cyane, kandi kurinda ubushyuhe bugaragara, kugabanya ikoreshwa ryingufu cyangwa gushimangira ikwirakwizwa ryubushyuhe.
