For this Major Qualifying Project, the team’s main goal was to design and create a working low-profile bass speaker. The team first reviewed previous years’ work in creating this speaker and discovered the airtightness of their speakers was not maintained and their actuator motors were not sufficiently robust. Based on these issues with the previous years’ speakers, the team conducted modifications to improve the speaker housing and actuator designs. This redesign resulted in two separate but similar designs for the speaker: an acrylic speaker model and a 3D printed speaker model. After conducting audio sweep tests and scanning laser doppler vibrometer (SLDV) tests, both speakers were determined to be airtight and work as intended.
