Technology Students Hear the Music
Students make their own speakers
Can you really make a speaker out of just a Styrofoam cup, copper wire and a magnet? Designing with Technology students found out it really does work. After studying electricity and the corresponding magnetic effects, the students built their own speakers and hooked them up to a radio to make music. We disconnected the built-in speaker of a radio and soldered on alligator clips so the students could hook up their own homemade speakers with the copper wire leads off their coil on the base of a cup.
