Bird chirps, freight trains, racetrack engines, sirens, phasor guns, organs (with additional push buttons), wind, jungle, and other noises may all be produced with this sound generator chip. Extremely low-frequency […]

This image shows a basic circuit that makes a chirping bird sound. It uses everyday parts, like a small transformer you’d find in a portable radio. How it works: The […]

This article presents a strong DJ MOSFET amplifier circuit design that is rather simple to construct and can generate a powerful 250 watts of music into a 4 ohm loudspeaker. […]

The discussed circuit produces sounds which resembles to an authentic buzzer. It operates using just two integrated circuits and a minimal number of components. When you press the switch S1, […]

In this article you’ll discover how to construct a very basic buzzer circuit using a piezo electric transducer, two resistors, a small coil, and a BC547 transistor. A buzzer is […]

Here is a circuit diagram for a two-tone siren that produces a loud sound with varying frequency. You can use it with any power supply voltage, so it is suitable […]
