Small SMD buzzer/ beeper help

Community Projects

Hi,

I’m working on a project and I’ve developed an board which connects via Bluetooth smart, I want to add an audio output to it. So that when it connects it beeps once and when disconnects it beeps twice.

I’m not sure what kind of beeper or buzzer (I don’t even know what it’s called) can I use.

Details:

→ Has to be SMD

→ Low energy consumption

→ Small size

→ Don’t need various audio output, just a single beep.

Any help would be greatly appreciated. :pray:

Thanks

You may need a transistor to drive some of the above. Seems that most need an AC signal. What do you have the BT connected to ? Does it have a spare digital output ?
