Hello all.

Would a container like

made of a thin flexible material  -like silicone- 

Exposed to sound waves; and a microphone on the cap at the neck, yield louder readings by amplifying all contractions/expansions of the spheric portion into a longitudinal up/down vibration into the neck ?

In other words, a microphone in a tube attached to the neck of an elastic balloon; would it behave as a sound magnifier ?  Would it be similar to a microphoned hearing funnel ?

And the narrower the neck, the greater the magnification ?
