Wireless odhiyo kugona kuteerera mimhanzi pasina chero waya pakati pevatauri vako uye yako stereo system. Iyo tekinoroji inoshandisa mafungu eredhiyo kufambisa iyo chiratidzo chekuteerera kubva kunobva kune vatauri. Iyo inozivikanwawo sewireless kutendeka kana Wi-Fi vatauri.
Muchinyorwa chino, ini ndichatsanangura kuti inoshanda sei uye nei ichiwedzera kufarirwa.
Wireless Speakers: Vanoshanda Sei?
Iyo Infrared Method
Vatauri vasina waya havana chinongedzo chakananga kune stereo system kana kumwe kunobva. Pane kudaro, iyo system inofanirwa kutumira chiratidzo chekuti vatauri vanogona kutora uye kushanduka kuita magetsi kuti vape simba coil yezwi mukati memutauri. Uye pane imwe nzira yekuzviita: infrared masaini. Zvakafanana nemashandiro anoita maremote control. Iyo stereo system inotumira kunze mwenje we infrared light, iyo isingaonekwe neziso rakashama. Iri danda rinotakura ruzivo mumhando yemapulses, uye mataurirwo asina waya ane masensa anogona kuona aya kutapurirana.
Kana iyo sensor yaona chiratidzo, inotumira masaini emagetsi kune amplifier. Iyi amplifier inowedzera simba rekubuda kwe sensor, iyo inofanirwa kutyaira izwi coil mutauri. Mushure meizvozvo, iyo inochinjika ikozvino inoita kuti izwi coil's electromagnet ichinje polarity nekukurumidza. Izvi zvinobva zvaita kuti diaphragm yomukurukuri izunguze.
Zvinokanganisa
Kushandisa masaini e infrared kune vatauri vasina waya kune zvimwe zvinokanganisa. Kune imwe, iyo infrared danda inoda nzira yakajeka kubva kune stereo system kuenda kumutauri. Chinhu chipi nechipi chinovhara nzira chinodzivirira kuti chiratidzo chisasvike kumutauri uye hachizoiti chero ruzha. Uyezve, masaini e infrared akajairika. Zvinhu zvakaita seremote control, mwenje, uye kunyange vanhu vanoburitsa mwaranzi ye infrared, izvo zvinogona kukonzera kukanganisa uye kuita kuti zviome kuti mutauri aone chiratidzo chakajeka.
Radio Signals
Pane imwe nzira yekutumira masaini pasina waya: redhiyo. Masaini eredhiyo haadi mutsara wekuona, saka haufanirwe kunetseka nezve chero chinhu chinovhara nzira. Uyezve, masaini eredhiyo haanyanyi kuvhiringwa, saka unogona kunakidzwa nemimhanzi yako pasina kutsvedza kana kusaenderana.
A Beginner's Guide kune Carrier Waves uye Modulating Signals
Chii chinonzi Carrier Waves?
Inotakura mafungu mafungu emagetsi emagetsi anogadziridzwa neine ruzivo-inotakura chiratidzo chekutumira isina waya. Izvi zvinoreva kuti vanotakura simba kubva kune imwe nzvimbo kuenda kune imwe, sekupisa uye nechiedza kubva kuZuva kuenda kuPasi, kana iyo inonzwika chiratidzo kubva kune inotumira kune ino headphone inogamuchira. Mafungu ekutakura akasiyana nemafungu eruzha, ari mafungu emagetsi, nekuti anogona kufamba nepakati pevacuum uye haadyidzane zvakananga nemamorekuru epakati.
Chii chiri Modulating Signals?
Modulating masaini anoshandiswa kuenzanisa iyo inotakura chiratidzo, uye ndizvo chaizvo masaini masaini akagadzirirwa madhiraivha emusoro. Pane nzira dzinoverengeka idzo modulating siginecha inogona kuenzanisa iyo inotakura wave, senge maitikiro modulation (FM). FM inoshanda nekuita kuti modulating chiratidzo igadzirise kuwanda kweiyo inotakura wave.
Wireless Analog Audio Transmission
Wireless mahedhifoni anowanzo shanda padyo ne2.4 GHz (redhiyo frequency), iyo inopa yakakura isina waya renji inosvika 91 m (300 ft). Kuti uchengetedze mutsauko mune inotakura wave frequency yakaderera uye yakapfupika, iyo odhiyo siginecha inongokwidziridzwa kana mahedhifoni inogamuchira yaideredza. Stereo odhiyo inotumirwa nekuwanda uye demultiplexing pamberi uye mushure meiyo frequency modulation process.
Wireless Digital Audio Transmission
Digital audio inoumbwa nekukasira snapshots yeamplitude yechiratidzo chekuteerera uye inomiririrwa nedhijitari. Hunhu hwedhijitari odhiyo hunogona kutsanangurwa nechiyero chayo chekuenzanisa uye kudzika-kudzika. Sample rate inoreva kuti mangani emunhu odhiyo amplitudes anotorwa sekondi yega yega, uye kudzika-kunoreva kuti mangani mabits anoshandiswa kumiririra amplitude yechero sample yakapihwa.
mhedziso
Saka, kuti zvipfupise, mafungu ekutakura mafungu emagetsi anotakura simba kubva kune imwe nzvimbo kuenda kune imwe, uye modulating masiginecha anoshandiswa kuenzanisa iyo inotakura chiratidzo, iyo inozoendeswa kune iyo mahedhifoni inogamuchira. Wireless analog audio transmission inoitwa kuburikidza nefrequency modulation, uye isina waya yedhijitari odhiyo kufambisa kunoitwa kuburikidza nedhijitari odhiyo masaini.
Kunzwisisa Nyika Yekutepfenyura Zviratidzo
Iwo Nheyo dzeRadio Waves
Radhiyo mafungu chikamu che electromagnetic spectrum, pamwe nechiedza uye infrared. Chiedza chinooneka chine wavelength yakasiyana 390 kusvika 750 nanometers, ukuwo infrared light ine kureba kwe 0.74 micrometers kusvika 300 micrometers. Masaisai eredhiyo, zvisinei, ndiwo makurusa eboka, ane urefu hwemasaisai emakiromita 1 kusvika ku100!
Masaisai eredhiyo ane mashoma mashoma pamusoro pemamwe marudzi emagetsi emagetsi, asi anoda mashoma ezvikamu kuti atore kubva kune stereo system kuenda kumutauri. Mutakuri wakabatana kune stereo system inoshandura masaini emagetsi kuita masaisai eredhiyo, ayo anobva atepfenyurwa kubva kune antenna. Kune rumwe rutivi, antenna uye inogamuchira pane sipika isina waya inoona chiratidzo cheredhiyo, ichichishandura kuita chiratidzo chemagetsi. Amplifier inobva yawedzera simba rechiratidzo kutyaira mutauri.
Radio Frequencies uye Kupindira
Mafambiro eredhiyo kwakakosha nekuti kufambiswa kweredhiyo uchishandisa ma frequency akafanana anogona kukanganisana. Iri rinogona kuve dambudziko guru, saka nyika zhinji dzakadzika mitemo inodzikamisa mhando dzeredhiyo dzakasiyana siyana dzinobvumidzwa kugadzira. MuUnited States, mabhendi emafrequency akagoverwa kumidziyo yakaita sematauri asina waya anosanganisira:
- 902 kusvika 908 megahertz
- 2.4 kusvika 2.483 gigahertz
- 5.725 kusvika 5.875 gigahertz
Aya mafambiro haafanire kukanganisa redhiyo, terevhizheni, kana masaini ekutaurirana.
Makaralı Protocol
Bluetooth iprotocol inobvumira zvishandiso kuti zvibatane kune mumwe nemumwe. Izvi zvinoreva kuti vatauri vasina waya vanogona kuve nezvinodzora kupfuura vhoriyamu uye simba. Nekutaurirana kwenzira mbiri, unogona kudzora kuti ndeipi track iri kuridza kana kuti nhepfenyuro yeredhiyo system yako yakarongedzerwa pasina kusimuka nekuichinja pane main system. Zvakanaka sei izvozvo?

Nhoroondo yeBluetooth: Ndiani Akaigadzira?
Bluetooth tekinoroji yatinoshandisa mazuva ese, asi unoziva here akaigadzira? Ngatitarisei nhoroondo yeiyi tekinoroji yechimurenga uye munhu ari shure kwayo.
Kugadzirwa kweBluetooth
Muna 1989, kambani yekuSweden yenharembozha inonzi Ericsson Mobile yakafunga kugadzira. Vakapa mainjiniya avo basa rekugadzira kapfupi-redhiyo tekinoroji iyo inogona kufambisa masaini kubva kumakomputa avo ega kuenda kumahedhifoni avo asina waya. Mushure mekushanda nesimba kwakawanda, mainjiniya akabudirira uye mhedzisiro yaive tekinoroji yeBluetooth yatinoshandisa nhasi.
Zita Rakabva Kupi?
Unogona kunge uchinetseka kuti zita rekuti "Bluetooth" rakabva kupi. Zvakanaka, ichokwadi chikamu chengano yeScandinavia. Maererano nenhau yacho, Mambo weDanish anonzi Harald “Bluetooth” Gormsson akabatanidza boka remadzinza echiDanish kuva dzinza rimwe chete guru. Sezvakangoita tekinoroji, Harald "Bluetooth" Gormsson akakwanisa "kubatanidza" madzinza ese aya pamwechete.
Bluetooth Inoshanda Sei?
Kana iwe uchida kunzwisisa kuti mutauri weBluetooth unoburitsa sei ruzha, unozofanirwa kujairana nemagineti. Heino rondedzero yekukurumidza:
- Bluetooth inotumira chiratidzo chinotorwa nemagineti mumutauri.
- Magneti anobva adedera, achiita masaisai eruzha.
- Aya masaisai eruzha anofamba mumhepo uye anonzwikwa nenzeve dzako.
Saka hezvo iwe unayo, sainzi kuseri kweBluetooth vatauri! Ndiani aiziva kuti zvakanga zviri nyore kudaro?
Chii chinonzi Buzz Nezve Near Field Audio Vatauri?
The Basics
Saka iwe wakanzwa nezve Near Field Audio (NFA) vatauri, asi zvese nezvei? Zvakanaka, aya matauriro asina waya anoshanda kuburikidza nemaitiro anonzi electromagnetic induction. Zvikurukuru, vane transducer, inova nzira inoyevedza yekutaura mudziyo unoshandura simba kuita chiratidzo chemagetsi. Zvino, kana iwe ukaisa foni yako pamusoro pechiratidzo ichi, inosimudzira ruzha kubva pachigadzirwa chako.
Bluetooth vs. Near Field Audio
Ngatienzanise uye tisiyanisa Bluetooth neNFA vatauri:
- Ose ari maviri haana waya zvachose, asi vatauri veNFA vanoshandisa akajairwa mabhatiri kugadzira simba ravo panzvimbo yemasaini eredhiyo.
- Nevatauri veBluetooth, unofanirwa kubatanidza foni yako kumutauri kuti unzwe ruzha. Nevatauri veNFA, zvese zvaunofanirwa kuita kuseta foni yako pamusoro uye wagadzirira kuenda!
Fun Fact
Wanga uchiziva here kuti vese vatauri vanoshanda nekuda kwefizikisi? Muna 1831, musayendisiti wechiRungu anonzi Michael Faraday akawana Faraday’s Law of Induction. Mutemo uyu unotaura kuti kana magineti ichipindirana nemagetsi emagetsi, inobudisa simba re electromotive, iro munyaya iyi, mafungu anonzwika. Zvakanaka chaizvo, handiti?
