HORN: To collect the sound. We used a large metal funnel.
DIAPHRAGM: To hold the stylus. We used the base of a tin can.
SOUND BOX Fixed to the horn, it increases the efficiency of the
transfer of sound to vibration. We made ours out of a small tin can.
STYLUS Used to transfer vibrations onto the recording cylinder.
Made out of a drawing pin and pushed through the middle of the diaphragm.
RECORDING CYLINDER: The recording cylinder rotates, moves along
and supports the wax on which the sound is recorded. Formed of two wooden
circles mounted on a piece of studding (long thread). Held apart and fixed
in place by wooden blocks.
WAX: Covers the recording cylinder and contains the impression
from the stylus. We used many layers of wax and smoothed it down with
a razor blade.
HANDLE: Turns the recording cylinder. Placed at one end of the
studding (long thread).
HINGE: Used to fix the horn-diaphragm-stylus unit onto the base.
It is able to move so that the position of the drawing pin on the wax
can be adjusted.
