Kuongorora giredhi revatauri, chiitiko chekunzwa chikamu chakakosha, icho chinozivikanwawo sechiitiko chemhando yekurira. Kune nzira dzakawanda dzekuvandudza kunaka kweruzha, sekuwedzera simba rekubuda reiyo odhiyo simba amplifier kubva kudunhu remagetsi, kuderedza kukanganisa; kugadzirisa mhinduro yefrequency kutsiva kushomeka kwemamwe ma frequency point emutauri kana mhango, zvichingodaro. Frequency division inzira inoshanda kwazvo yekuvandudza ruzha rwemhando. Kana iri yakaderera-frequency, yepakati-frequency, uye pamwe yakakwirira-frequency vatauri vane yakamanikana ma frequency mabhendi, zvakanaka kwazvo kuita, uye mhedzisiro yacho zvakare yakanaka kwazvo. Nekudaro, zvakanyanya kuoma kugadzira mutauri ane yakazara frequency bhendi ye20Hz～20kHz odhiyo, uye zvingangoda zvemhando yepamusoro-soro kugadzira mutauri akazara-ane mhedzisiro iri nani. Kusarudza 2.1-channel musanganiswa ndeyemunda wemagetsi crossover uye inzira inowirirana yekuvandudza ruzha rwevatauri. Izvi zvakafanana kune vanotakurika vatauri vebluetooth. Kugadzira mobile 2.1-channel speaker inzira yakanaka yekuvandudza ruzha rwemhando. Kunyanya iyo inokatyamadza yakaderera-inonzwika yekuteerera inonetsa kuenzanisa nembiri-chaneli kana mutauri mumwechete.

Kubva paCS8611E single-chip mobile 2.1-channel bluetooth speaker solution plan, dual-cell lithium bhatiri yakabatana munhevedzano ne8.4V semagetsi, uye boost chip CS5036E inokwidziridzwa kusvika ku12V kusimbisa CS8611E kupedzisa 20W. + 2 × 10W kubuda; uye CS5090EUSB5V inoshandiswa pakuchaja Zviri nyore kuisa mabhatiri maviri e-lithium munhevedzano ine 8.4V yekuchaja manejimendi chip. Inopa chiitiko chekunzwa chinofananidzwa neyakajairwa 2.1 vatauri kana lithium bhatiri iri simba sosi.

Iyo yakazara basa block dhizaini ndeiyi inotevera:

Poshi. Hurongwa hunojekesa:

Ichi chirongwa ndeye 20W + 2 × 10W nhare 2.1 odhiyo amplifier inosimudzira yekuchaja manejimendi musanganiswa. Tarisa kuchirongwa. Iyo magetsi emagetsi maviri 18650 mabhatiri akabatana munhevedzano, akakamurwa kuita matatu makuru mazinga:

1. Sarudza CS5090 yakasimudzira dual-cell lithium bhatiri yekuchaja IC, chengetedza chinyakare kunze adapta, uye shandisa USB tambo kupedzisa maviri-sero lithium bhatiri charge;

CS5090E ndeye USB_5V yekupinda inoshandiswa kubatanidza mabhatiri maviri e-lithium munhevedzano ine 8.4V yekuchaja manejimendi chip. Yakavakwa-in intact trickle, inogara iripo, uye inongogara voltage yekuchaja maitiro. Chinhu chikuru ndechekuisa inogadzirisa basa, chero USB interface ine hombe kana diki ikozvino inogona kubhadhariswa zvakajairika, uye iyo yakanyanya kuchaja ikozvino 1.5A. Uye zvakare, ine akasiyana akachengeteka uye akavimbika ekugadzirisa matanho uye yekuchaja mamiriro echiratidzo, uye zvakare inounza NTC tembiricha yekudzora basa.

2. Mabhatiri maviri e-lithium akabatanidzwa mumutsara ne 8.4V semagetsi emagetsi, ayo anowedzerwa ku12V ne boost chip CS5036E kupa simba kune simba amplifier IC; CS5036E yakavakirwa-mukati 12A, MOS yakakwirira-inoshanda DC-DC inosimudzira shanduko chip. Iyo periphery yakanyanya kupfupika, iyo yekuisa voltage sikeri yakafara kubva pa3V kusvika 12V, uye kushanda kwayo kwakakwira se93% kana kupfuura. Ikozvino muganho kukosha kunogadziriswa pane periphery, iyo iri nyore kuenzanisa bhatiri. Iyo EQA16 package inosarudzwa, ine mabasa akadai sepamusoro-tembiricha kugadzirisa uye over-voltage kugadzirisa.

3. The audio power amplifier chip inosarudza CS8611E, iyo inopa 20W + 2 × 10W simba rinobuda pa12V; CS8611E ndeye 2 × 15W+30W yakatsaurirwa 2.1-chiteshi kirasi D odhiyo yemagetsi amplifier. Yepamberi EMI yekudzvanya tekinoroji inogonesa kushandisa isingadhure magineti bead mafirita pachiteshi chinobuda kusangana neEMC zvinodiwa. Yakabatana nekupararira-spectrum mashandiro, iyo FM radio inewo yakanakira kuvhara maitiro. Mukuwedzera, kushanda kweanopfuura 90% kunoita kuti zvive zvisina kufanira kushandisa imwe radiator kana uchiridza mimhanzi.
