Two Sides To A Speaker

Student: Ethan McNutt

District/Region: Chignecto Central Region

Event: 2007 Canada-Wide Science Fair

Ethan is a student at Bible Hill Junior High School and his project investigated the elimination of deformed sound waves produced at the back of a speaker diaphragm.

The innovative design of the two sided speaker which has two diaphragms placed back to back on a single voice coil created phase cancellation and resulted in a decrease in deformed sound waves and a more even frequency response.

Ethanís project won two Bronze Medals at the 2007 Canada-Wide Science Fair. He is one of Nova Scotia's young scientists and tomorrow's innovators. Congratulations, Ethan!
