Estimating Acoustic Performance of a Cell Phone

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 to better design cell phone cavities for optimum performance.
