Passive high-pitched alarm horn No driver alarm audio head Piezo buzzer
This is a piezoelectric buzzer, which must be driven by a 2-4K square wave to sound.
Note: The double-sided tape on the back of the speaker is not sticky after the speaker has been in stock for a long time, so you need to replace it yourself.
