There are many ways to make the sound effect work. I decided to use a very simple one with a finished module, but can of course build it yourself.

First drill two small holes in the Altoids tin for the push button and the speaker and use tape to insulate it. The Velcro helps to hold the recording parts in place. Everything else is glued to the tin with hot glue.

Because the fabric of the pillow inlet is to thin the plastic container supports the push-button from behind and is glued to the inside of the pillow as you can see in picture number 5.



The tape that you can see in pictures number 4 and 5 prevents the fabric of the pillow from fraying.



It bothered me, that the push buttons could still be seen through the pillow case. That why I ironed fusible interfacing to the inside of it.





You are done, organize the pillows on your sofa and have a lot of fun, but make sure that nobody gets a heart attack...
