This week the team explored the physicality and materials of sound with their project BassQuake. Although audio visualisers are commonplace, BassQuake uses the physical movement of the speaker’s flexible membrane to visualise the bassline of a song. This movement of the aluminium foil membrane closes a circuit which in turn lights up the SMD LEDs around the middle of the speaker. A coil of enamelled copper wire with a stack of magnets rest in the body of the device, and music is input through an aux cable.

Through the process of building this device, the team learned about how speakers are constructed, experimented with different materials to understand how to generate sound most effectively, and how to amplify the results.
