I got some guidance back in November 2019 about the transducer hooking up to the noisy cricket, and suggested speakers to connect. I’m a beginner with a few things so I still need some help. Here’s what I want to do with these components:
I have a 4-foot cloud buster balloon that I’m inflating. I want the surface transducer to turn the inflated balloon into a speaker, and the noisy cricket to function as an amplifier.
I don’t think that a surface transducer is going to work with a balloon.
Surface transducers need something rigid to vibrate like a pane of glass or a hollow wooden door if they are going to make any sound. On a balloon, you’re just going to vibrate the small section that the transducer is attached too and nothing else. I doubt that you’d be able to hear much of anything at all.
If you want sound to appear to be coming from a balloon, you’d need to hide a speaker inside. The Balloon isn’t going to affect the sound level at all so you’d need a speaker large enough to produce the sound level you were looking for outside a balloon and then you’d need to figure out how to hide it inside.

This is a good answer. If I may draw an analogy, imagine trying to make noise using a drum head that wasn’t stretched across a drum. It wouldn’t make much more sound than drumsticks on a tshirt. Not until it’s mounted and tightened does it become rigid enough to rock & roll.
You can substitute any stringed instrument for the drum. Until the strings are tightened, no sound.
