Kab lus no qhia pom kab mob kev co. Tus neeg hais lus kev co tau qhib thaum cov kab raug tso rau hauv dej.

Khoom siv

Cheebtsam: lub hom phiaj dav dav bipolar kev sib txuas (BJT) NPN/PNP transistors - 5, 1 kohm qis zog tiv thaiv - 1, 10 kohm qis zog tiv thaiv resistor - 1, 100 ohm (lossis 10 ohms) siab zog resistor - 1, pawg thawj coj saib, hais lus vibration - 3.

Cov cuab yeej: hlau stripper.

Cov khoom siv yeem: solder, Schottky/silicon diode (tsis txhob siv lub zog qis diodes).

Yeem cov cuab yeej: cov hlau txuas, ntau lub ntsuas.

Kauj ruam 1: Tsim Circuit Court

Tus hais lus kev co yog ua qauv li 500 ohms. Ntau tus neeg hais lus muaj qhov sib txawv resistor qhov tseem ceeb.

Xam qhov siab tshaj plaws kev hais lus tam sim no:

Ivbs = (Vs - Vsat) / (Rspeaker + Ro)

= (9 V - 0.2 V) / (500 ohms + 100 ohms) = 8.8 V / 600 ohms

= 14.66666666 mA

Nco ntsoov tias koj yuav xav tau siv 10 ohm Ro resistor tus nqi hloov ntawm 100 ohms kom nce tus nqi tam sim no.

Kuv siv lub qub PSpice simulation software.

Qhov siab tshaj plaws kev hais lus tam sim no yuav luag zoo ib yam li qhov kwv yees.

Kuv tsim lub voj voog ntawm ib daim duab los qhia. Kev siv lub rooj tsav xwm matrix yog txoj hauv kev zoo dua vim muaj kev pheej hmoo ntawm dej ua rau koj cov duab hluav taws xob puas tsuaj.

Kuv siv blu tack los txuas lub 9V roj teeb, Circuit Court, thiab coj mus rau lub rooj ntoo.

Kauj ruam 5: Xeem

Kev sim qhia kuv cov duab puab ua haujlwm.
