Consumers demand smaller electronics devices with more features and capabilities. Making devices smaller provides challenges to engineers to maintain the acoustic performances as enclosed acoustic volume sizes are reduced. This paper discusses the requirements for coupled structural-acoustic simulation and demonstrates the application of this technology to cell-phone acoustic design. Due to the smaller volume sizes, the low frequency response of the cell phone is affected. The frequency response rolls off faster at low frequencies when smaller microphone back volumes are used. The present work deals with studying this effect on a simple cell phone model with the finite element package, Abaqus. The results from the simulation can be used in better designing cell phone cavities for optimum performance.
