Bluetooth Speaker in a vacuum bag

So ... I put a Bluetooth speaker inside one of those vacuum bags for clothes.
When I took the air out of the bag, the sound coming out of the speaker was very low, but still audible.
When I opened the bag, the speaker was silent for about 1 second before returning to it's normal level.
Can anyone tell me the reason for the 1 second of silence?

Have a look at how a speaker actually works. Most likely the vacuum imploded the voice coil around the pole piece, and there's a good chance the speaker's cone, spider and voice coil are damaged, you just haven't realized it yet.


Here's an example of a normal can and an imploded can, compared to the voice coil.

Oh thats easy, the speaker simply needed to take a breath. It is like you would put your head in the bag, remove the air, and then open the bag - you would also need one second to take a breath before you could talk about your experiences inside the bag....
