Hello. I'm trying something unique. I'm sending a sound signal to a speaker. But I want the sound to stop when I insert a USB drive into USB female port. The port isn't connected to a computer. It's free-standing—just a plain old unpowered piece of metal.
How can I accomplish this? A micro toggle switch inside the USB port? Some kind of spring that keeps two wires apart when the USB goes in? There isn't a way to use the USB port outputs themselves, right?
Here's a drawing of what I'm trying to accomplish.
Thanks for your help.

Only safe way I can see to do it would be to drill a small hole through the back of the usb socket.
Then insert a pin, that is pushed by the usb stick.
Then other end of the pin then actuates a normally closed switch into the open position.
Any other way of doing it involves electronic circuits.
