Transducer Theory

A transducer is a device that converts energy from one form into another; for example, a speaker converts an electrical signal into a sound wave. This course focused on electroacoustic audio transducers, specifically microphones and loudspeakers. Topics included fundamentals of acoustics as well as the design of various loudspeakers (acoustic suspension, bass-reflex, transmission line, electrostatic, and horn) and microphones (dynamic, ribbon, and condenser).

• Designing and Building a Loudspeaker

  Report

  Kerline Moncy, Diego Ugaz, and I teamed up to design and construct a loudspeaker. Our speaker was designed using the bass reflex model and consisted of a GRS full range driver, a Bose tweeter with a two-way passive crossover, and a single vent. We used WinISD to design the enclosure based on the parameters of our drivers. As a final touch we painted the entire enclosure with chalkboard paint to allow people to draw on our speaker with chalk. After a listening test our class voted our speaker best sound!
