IEEE Rochester Section participated in the 27th annual E3 Fair at RIT Clark Gymnasium on 27 April.
IEEE Rochester Section Senior Member, Joseph DeVita, brought the Musical Engineer back to the 2017 E3 Engineering and Technology Fair with a presentation about the science of sound. Middle school students were introduced to the electro-mechanical fundamentals of audio speakers, sound amplification and sound pressure measurement. There was a hands-on demonstration of a do-it-yourself picnic-plate speaker. Kits consisting of a Styrofoam plate, voice coil wire, spools, business cards and magnets were given to students interested in building their own versions at home.
Visitors to the IEEE display were impressed with the level of “fidelity” the 98 cent speaker was able to generate. This ‘second-generation’ DIY speaker was based on a paper-plate design used by IEEE student members at the University of Rochester in their STEM outreach programs.
Our thanks go out to Sound Source in Rochester NY for providing commercial speakers for tear downs. We also wish to thank the students and educators that participated, for their interest and thoughtful inquiries.
