"Hello. What you're hearing is a demonstration of my improved carbon microphone. It uses a thin diaphragm made of white pine to collect sound from the air, and then transmits this sound to a carbon rod on the back. This rod bridges the input and output terminals via four microphonic contacts, which change resistance in response to the sound waves. Having multiple contacts in parallel improves the sound quality, while having them in series reduces crackling. The microphone can tilt to adjust the pressure on the contacts due to gravity, which in turn adjusts the sensitivity of the microphone. The result sounds far better than the original prototype, although I'm sure it could be improved further. Thank you for listening."
