Chokwadi unoda kuziva kuti chii a vu mita kana kuti zvinoshanda sei. Zvingaite senge zvisinganzwisisike, asi ndine chokwadi chekuti pane kanopfuura kamwe chiitiko iwe wakaona kana kushandisa imwe kanenge usingazive kuti chaive chimwe chemidziyo iyi. Uye ivo varipo mune yakawanda mimhanzi zvishandiso, zvinosanganisira kusanganisa consoles, inoitwa nesoftware mune mamwe maodhi ruzha senge maMP3 players, akaenzana, nezvimwe.
Muchikamu chino iwe uchadaro ziva zvese zvaunoda dzidza nezve mita yemiyero, mashandisiro ayo, mashandiro ayo, kwaunogona kutenga imwe, uyezve kuti ungavaka sei imwe uchishandisa Zvemagetsi zvigadzirwa yakapusa ...
Chii chinonzi mita yeVU?
El vu mita Icho chigadzirwa chinokwanisa kuyera vhoriyamu mwero muzvikamu zvakakosha zvandichataura nezvazvo gare gare. Midziyo iyi inogona kuve yedigital uye analog, iyo yekupedzisira iri inonyanya kufarirwa nhasi
Iyo yakajairika nhanho yemamita inonyatso kuverengerwa inofamba coil kana galvanometer ine imwe damping. Izvi zvichapihwa simba neiyo yakazara wave gadziriso iyo yakabatana netambo odhiyo kuburikidza netigero kuramba. Nenzira iyoyo iwe haudi chero yekuwedzera magetsi sosi, ingori simba rechiratidzo chiratidzo pacharo.
Nenzira iyoyo, unogona ratidza kusiyanisa kwemagetsi echiratidzo cheodhiyo, Kubvumira mushandisi kuti aone vhoriyamu nhanho nguva dzese. Vanozviita kuburikidza nesingano padhiki kana vari analog, kana kuburikidza nemaLED kana ari edhijitari.
Haufanire kuvhiringidza mita yematanho ne kuyera ruzha (mita yemazinga enzwi). Ivo havana kufanana, uye ekupedzisira anoshandisa iyo yeyuniti yedecibel kana dB kuyera algorithmic kusvetuka mudanho rezwi ravari kutora ...
VU: chikwata
La vhoriyamu unit VU (Vhoriyamu Chikamu) inotsanangurwa se «Iyo vhoriyamu chiratidzo inoratidza 0 VU kana chakaburitswa nechomukati kuramba kwe600 ohms chakabatanidzwa, kune sine wave chiratidzo che1000 Hz uye amplitude ye +4 dBu.".
Izwi rakagamuchirwa zviyero zvevhoriyamu zvine chekuita nekuona kwevanhu kweakanyanya chiratidzo chiratidzo.
Applications
Kuve mudziyo wekuyera vhoriyamu, iyo mita yemiyero ine kuwanda kwekushandisa pazviridzwa zvine mutsindo. Semuenzaniso, unogona kuiwana mune vamwe vaisanganisa, zvakaenzana, vatambi vemhanzi, michina yemimhanzi, zvirongwa zveaudio, uye yakareba etc. Saka zvirokwazvo pane kanopfuura kamwe chiitiko wakave uine imwe pamberi pako uye waisatomboziva kuti yainzi vumeter.
Unogona shandisa kuti uwane nenzira yekuona yakajeka iyo nhanho yekuenzanisira, kuti ubatanidze kune odhiyo yekuburitsa kwechigadzirwa chawakasimudza, nezvimwe. Vamwe vanogadzira akaomarara LED nziyo sezvinhu zvakapfava zvekushongedza, zvekuti vanovhenekera kune "kurova" kwemumhanzi. Iko mikana yakakura kwazvo, iwe sarudza ...
Kwatenga
Kana iwe uchida tenga vu mita, ipapo iwe unofanirwa kuziva kuti ivo havana kunyanya nyore kuwana mune zvimwe zvitoro, asi iwe unogona kuwana imwe yacho mune zvimwe zvitoro zvine hunyanzvi kana epamhepo yekutengesa mapuratifomu. Semuenzaniso, heano mamwe mazano ekutenga:
- Nobsound, skrini yakaoma kunzwisisa kuratidza huwandu hwenzwi kana iwe uchibatanidza kune yekubuditsa odhiyo. Iyo skrini ine resolution yezvinhu zvine mwenje zve15x15.
- Kongnijiwa, analoginen yakakwira chaiyo nhanho yemamita.
- 2 metres uye pcb kubatanidza kune gudzazwi rinobuda muzvirongwa zvako.
- Stereo level mita ine 2x15 ma LED.
- Velleman MiniKits yakapusa mwero we LED mwero
- Imwe imwe nzira yakafanana neiyo yapfuura iine maGreen matema, uye yero uye tsvuku kutara huwandu hwakawanda.
- Tiamu, yakapusa mita yemiyero ine LM3915 chip uye maLED.
Vaka mita yekumusoro yakaenzana
Iwe unazvo nzira dzakasiyana siyana dzekuvaka nera mita nenzira yakapusa. Imwe yacho ndeye IC LM3914, iyo LM3915, kana LM3916. Maviri akakurumbira machips munyika yemagetsi. Pamusoro peiyo chip, sezvaungaona mumufananidzo wekare, iwe unozodawo ma LED emavara aunosarudza kuratidza iro vhoriyamu kutaridzika, uye zvimwe zvimwe zvinhu zvakaita seanopikisa, potentiometer, uye capacitor.
Kuti unzwisise zviri nani gungano rayo, unogona kushandisa imwe yeiyi dzidziso mavhidhiyo kwavanoitsanangura nhanho nhanho:
Iwe zvakare une dzimwe sarudzo, seiyi imwe yakapusa iyo inoshandisa migero miviri yeLED zve stereo:
Mune imwe iyi yaakashanda maIC matatu izvo zvandataura pamusoro apa kutarisa mhedzisiro mune yega yega:
