What you are describing is a carbon microphone. This consists of a diaphragm behind which are placed granules of carbon. When the diaphragm vibrates due to variations in sound waves, it acts to compress the carbon granules -thus varying the resistance of the carbon granules as a whole. This variation in resistance is used to modify a current which is then amplified.
