So I am in a fantasy football league where our loser must hang a portrait (of anything the winner chooses) on their wall until the next season begins. Our loser is beginning to emerge and I had the idea of trying to create a portrait that somehow has a hidden speaker inside that we can play spooky sounds from. The loser is a superstitious and cowardly in nature, was thinking of hanging a creepy 1800s portrait of an old woman or a creepy clown. Then having a speaker randomly play someone whispering latin or softly weeping. Open to suggestions here.

However the challenges are as follows:

• Need to hide the speaker without the loser detecting it
• Need to make the speaker function on a timer possibly to make the sounds play AFTER it has entered the home
• Need to ensure the speakers don’t lose power before it has entered the home

No idea if this is the right subreddit but would love some sound eggheads to point me in the right direction.
