Buzzer Basics: Technologies, Drive Circuits, and Live Sound Demos
概要
In this video, we break down the basics of buzzers—covering everything from magnetic vs. piezoelectric designs to indicators vs. transducers, and even demonstrate real-world buzzer sounds. Whether you're designing a medical device, a consumer product, or an embedded system, understanding how buzzers work is essential.
What you'll learn:
- The difference between magnetic and piezo buzzers
- How self-driving (indicator) and externally driven (transducer) buzzers operate
- Key electrical specs: voltage, frequency response, impedance, and sound pressure level
- Mounting styles and use-case examples
- Live demos of buzzer tones, including multi-tone and IEC-certified medical alerts
