Please excuse the crude drawing. One, I don't know if this can even work in theory. If it can work then I'm having trouble figuring out what values for the components. Any help would be appreciated.
B2 is a momentary switch the normally closed.
What I want this circuit to do is briefly behave like a short when the button is pressed but then return to being able to use the microphone. When the button is released I want it to again act like a short and then, again, return to being able to use the mic. Each time it acts like a short I want it to be in this state for about .1 second or so. Perhaps .2 second to return to normal.
To describe that I want it's probably easier to describe what I hope this circuit does....
1. When the circuit is connected to the 1.8V power, nothing will happen with the transistor and all power goes through the MIC.
2. When the button is pressed the, current will pass though C1 until is charged and then C1 will make that part act like a open circuit an all current will pass though the MIC. This will act like a short for a very brief period. I want this to happen and I want it to take about .2 seconds to go from closed circuit to open.
3. When the button is released the capacitor creates a voltable drop across the base of the transistor (switching it on). Power then flow though the transistor until the voltable across the base drops below .7 volts at which point the transistor turns off. I want the transistor to stay about about .2 seconds.
I'm I out of my mind with this design?
