Constant ground to a triped ground?

Hey all,

Stumbled on this forum from a web search.

Here is what I'm up against. I put a sound toy in my cb radio. To make it play its sound, I have to hit a switch which grounds the toy. I want to hook it up so when hit the transmit button, it will play. There are 2 wires coming out of the toy, 1 to trigger it and one to ground. I want to hook it up to the transmit wire on the mic, but its a constant ground when your transmitting. The toy needs only to be tripped so to say. It wont work if held to ground.

If ya made sense of any of this, I need to make a circuit that will just trigger the toy, no matter how long the transmit key is held down.

Any ideas?

Thanks!
 
Capacitor and resistor in parallel. Probably 0.01uF (10nF) in parallel with 2.2 megohms (2M2).
