Attaching a passive buzzer to a PAM8403 audio amplifier


So i wanted to make this project Adding voice and facial expressions to mini hash humanoid robot | Hash Robotics - YouTube, but the thing is that I only have a this passive buzzer:

The person in the video did not specify the type of speaker but would the image that I have put above work?

No, a cheap filter-less class-D amplifier relies on the inductance of a speaker.
A piezo would present a short to the amplifier output.
And most of the passive buzzers I see on that page are actually active buzzers.
Only a 'real' 4ohm or 8ohm loudspeaker would would work with the PAM8403.

Use speaker from Iphone

I'm sure there are cheaper miniature speakers available, a quick search found
many possibilities.
