When sampling speaker designs, to fully understand the
technology we met with a number of technicians, including Dr Francis Sweeney
from the electronics department. With us we took an initial unsuccessful BARE
conductive paint sample and the audio jack that we hoped to use. Here we spoke
through our project intentions and queries as to why our samples were not
working.
Dr Francis Sweeney first used a multimeter to test the audio
jack we were using. From this we were able to establish the sections of the audio
jack (pictured) and identity the three wires that came out when the plastic
coating was removed.
The bronze wire was the ground, the Blue was Channel 1 and
the Red was channel 2. These colours however were not the true colours of the
wires as we had first thought. Each wire had a varnish coating surrounding it
to ensure that the wires did not directly touch each other when inside the
plastic coating. We were informed that this varnish would need to be scraped
off at the end of the wires using a scalpel before attaching it to the
electromagnet coil made for the speaker.
Dr Sweeney also spoke through a possible circuit diagram for
a double-coiled structure (also pictured). This instruction directed us for
later samples.
