Abstract:Abstract This report describes the design of a low frequency sound source. The design of this sound source started by analyzing a basic loudspeaker enclosure. An analogous lumped element circuit was created to represent all parameters of such a system. From this circuit a number of analytical transfer functions were created to investigate its behavior. The transfer functions were used to validate the finite element model which was created next. The differences between both models were found to be negligible. Leading to the next step which was to create a number of enclosures and perform finite element calculations for each one. By comparing each enclosure for a number of criteria a choice between enclosures could be made. After choosing the enclosure that performed best, a detailed design was made, which will be used for construction purposes. This report concludes by showing the blueprints of the chosen enclosure.
