Which essential component of the phonautograph transmitted the vibrations from the incoming sound to the stylus via a thin membrane?
Answer
The diaphragm
The process of capturing sound relied on several key mechanical components. After sound waves were collected, usually by a horn or funnel, they struck the diaphragm. This component was described as a taut, thin membrane that vibrated in sympathy with the pressure changes of the incoming sound waves. Attached directly to the center of this diaphragm was the lightweight stylus, which moved precisely according to the diaphragm's vibrations to inscribe the record.
