Chero zvazvingava, buzzer inogona kuva nzira isingadhuri uye yakavimbika yekubvuma murairo, ichiratidza chimiro chemidziyo kana maitiro, kukurudzira kupindirana, kana kusimudza alarm.
Chaizvoizvo, buzzer inowanzova iyo yemagineti kana piezoelectric mhando.Sarudzo yako inogona kuenderana nehunhu hwechiratidzo chekutyaira, kana iyo inobuda redhiyo simba rinodiwa uye yemuviri nzvimbo iripo.Iwe unogona zvakare kusarudza pakati pechiratidzo uye transducer marudzi, zvichienderana nemanzwi aunoda uye nedunhu-dhizaini hunyanzvi hunowanikwa kwauri.
Ngatitarisei misimboti kuseri kwemaitiro akasiyana tobva tafunga kana iyo magineti kana piezo mhando (uye sarudzo yechiratidzo kana actuator) ingave yakakodzera purojekiti yako.
Magnetic buzzers
Magnetic buzzers anonyanya kufambiswa nemidziyo, kazhinji inoda inodarika 20mA kuti ishande.Mhepo inoshandiswa inogona kunge yakaderera se1.5V kana kusvika ku12V.
Sezvinoratidzwa nenhamba 1, iyo meshini inosanganisira coil uye inoshanduka ferromagnetic disk.Kana iyo yazvino ichipfuura nepacoil, dhisiki inokwezvwa yakananga kune coil uye inodzokera kunzvimbo yayo yakajairika kana ikozvino isiri kuyerera.
Uku kutsauka kwedisiki kunoita kuti mhepo iri pedyo ifambe, uye izvi zvinodudzirwa seruzha nenzeve yemunhu.Ikozvino kuburikidza nekoiri inotarirwa neiyo inoshandiswa voltage uye iyo coil impedance.
Mufananidzo 1. Magnetic buzzer kuvaka uye kushanda musimboti.
Piezo buzzers
Mufananidzo 2 unoratidza zvinhu zvepiezo buzzer.Dhisiki yepiezoelectric zvinhu inotsigirwa kumicheto mune yakavharirwa uye magetsi ekubatanidza anogadzirwa pamativi maviri edhisiki.Magetsi akaiswa pamaelectrode aya anoita kuti piezoelectric zvinhu zvisanduke, zvichikonzera kufamba kwemweya unokwanisa kuonekwa seruzha.
Kusiyana nemagineti buzzer, piezo buzzer chinhu chinofambiswa nevoltage;simba rekushanda rinowanzokwira uye rinogona kuva pakati pe12V ne220V, asi ikozvino iri pasi pe20mA.Iyo piezo buzzer inofananidzwa se capacitor, nepo iyo magineti buzzer inofananidzwa sekoiri munhevedzano ine resistor.
Mufananidzo 2. Piezo buzzer kuvaka.
Kune ese ari maviri marudzi, kuwanda kweinokonzeresa inonzwika toni inotarwa neiyo frequency yechiratidzo chekutyaira uye inogona kudzorwa pamusoro pehupamhi.Kune rimwe divi, nepo piezo buzzers ichiratidza hukama hune mutsara pakati pesimba rekuisa chiratidzo uye inobuda redhiyo simba, iro redhiyo simba remagineti buzzers rinodonha zvakanyanya nekuderera kwesimba rechiratidzo.
Hunhu hwechiratidziro chekutyaira chauinacho hunogona kukanganisa kuti ukasarudza magineti kana piezo buzzer yechishandiso chako.Nekudaro, kana ruzha rwuri chinhu chakakosha chinodiwa, piezo buzzers inogona kuburitsa yakakwira Sound Pressure Level (SPL) kupfuura magineti buzzers asi zvakare inowanzova netsoka yakakura.
Indicator kana transducer
Sarudzo yekuti yekusarudza chiratidzo kana transducer mhando inotungamirwa nemhando yemanzwi anodiwa uye dhizaini yedunhu rakabatana kutyaira nekudzora buzzer.
Chiratidzo chinouya nedhiraivha yekutyaira yakavakirwa muchishandiso.Izvi zvinorerutsa dhizaini yedunhu (mufananidzo 3), ichigonesa plug-uye-kutamba nzira, mukutsinhana nekuderedzwa kuchinjika.Nepo iwe uchingoda kuisa dc voltage, munhu anogona kungowana inoenderera kana pulsed odhiyo chiratidzo sezvo frequency yakagadziriswa mukati.Izvi zvinoreva kuti kurira kwe-multi-frequency senge sirens kana chimes hazvigoneke neanoratidza buzzers.
Mufananidzo 3. An indicator buzzer inobudisa inzwi kana dc voltage inoshandiswa.
Isina dhiraivha yekutyaira yakavakirwa mukati, transducer inokupa iwe kuchinjika kuti uwane akasiyana manzwi uchishandisa akasiyana ma frequency kana anopokana masaisai.Kuwedzera kune yekutanga inoenderera kana pulsed ruzha, unogona kuburitsa manzwi akadai seyambiro-matani-yambiro, siren kana chimes.
Mufananidzo 4 unoratidza dunhu rekushandisa kune magineti transducer.Shanduko yacho inowanzoita bipolar transistor kana FET uye inoshandiswa kukwidziridza iyo excitation waveform.Nekuda kweiyo coil inductance, iyo diode inoratidzwa mudhayagiramu inodiwa kubata iyo flyback voltage kana transistor yakadzimwa nekukasira.
Mufananidzo 4. A magnetic transducer inoda chiratidzo chekusimudzira, amplifier transistor uye diode yekubata induced flyback voltage.
Iwe unogona kushandisa yakafanana excitation circuit ine piezo transducer.Nekuti piezo transducer ine yakaderera inductance, diode haidiwi.Zvisinei, dunhu rinoda nzira yekugadzirisa zvakare magetsi apo shanduko yakazaruka, iyo inogona kuitwa nekuwedzera chigadziro panzvimbo ye diode, pamutengo wepamusoro wekuparara kwesimba.
Mumwe anogona zvakare kuwedzera mwero wekurira nekusimudza peak-to-peak voltage inoshandiswa pane transducer.Kana iwe ukashandisa yakazara-bhiriji reketi sezvakaratidzwa mumufananidzo 5, iyo yakashandiswa voltage yakakura zvakapetwa kaviri pane iripo magetsi ekupa, iyo inokupa inosvika 6dB yakakwira kubuda odhiyo simba.
Mufananidzo 5. Kushandisa bhiriji redunhu kunogona kaviri mhepo inoshandiswa kune piezo transducer, ichipa 6 dB imwe simba redhiyo.
Mhedziso
Buzzers iri nyore uye isingadhuri, uye sarudzo dzinogumira kune mana ekutanga mapoka: magineti kana piezoelectric, chiratidzo kana transducer.Magnetic buzzers anogona kushanda kubva pakadzika ma voltages asi anoda madhiraivha epamusoro kupfuura marudzi epiezo.Piezo buzzers inogona kuburitsa yakakwira SPL asi inowanzova netsoka yakakura.
Iwe unogona kushandisa chiratidzo buzzer ine chete dc voltage kana kusarudza transducer kune mamwe manzwi akanyanya kana uchikwanisa kuwedzera inodiwa yekunze sedunhu.Nechinofadza, CUI Zvishandiso zvinopa huwandu hwemagineti uye piezo buzzers mune chero chiratidzo kana transducer marudzi kuita kusarudzwa kwebuzzer yedhizaini yako kuve nyore.
