The goal of our project is to create a low-profile wall-mounted home speaker system with a focus on an improved passive radiator design. This project helps idealize passive radiator injection molding techniques through online research, contact with acoustic professionals, 3D modeling, 3D printing, software simulation, and injection molding testing. Previous projects were tested using vibrometer technology and later optimized to obtain ideal resonant frequencies. Multiple injection molding techniques were used to create silicone surrounds for the passive radiator system. Improvements were made to the passive radiator Solidworks model to achieve an ideal resonant frequency and secure the material to the 3D printed parts using different geometrical configurations.
