Product Introduction
Baby Overview: Universal passive buzzer with a resistance of 16 ohms. The driving method and working principle are the same as ordinary speakers
A passive buzzer means that an audio drive signal is needed to make it sound, which corresponds to an active buzzer. The active buzzer only needs to be energized with direct current to make it sound, and the active buzzer has its own oscillator!
