A loud speaker has been widely used as a major actuator in the field of active noise control (ANC). In this paper, the design procedures for a non-ported conventional speaker that must meet restrictive size constraint as well as required sound pressure level at a targeted frequency for an acoustic control was presented. Dynamic model of a speaker that includes linear and nonlinear effects such as radiation resistance on speaker damping, voice coil electrical resistance has been developed and its responses were compared to measured data. The effects of speaker design parameter variations on a sound pressure and power consumption were also assessed experimentally and through simulation. It was found that the simulation results are well collated with experimental data and the desired objective has been met.
