Patent ID: 7890312

Claim:
A method for optimizing the performance of a loudspeaker port, the method comprising: defining at least one geometric associated with the loudspeaker port; modeling a bi-directional fluid flow through the loudspeaker port based upon the at least one geometric utilizing a Computation Fluid Dynamics (“CFD”) modeling method and where modeling calculations are executed for two complete transducer cycles before data is collected, where the data is non-statistical data; obtaining a representation of the bi-directional fluid flow through the loudspeaker port; analyzing the representation of the bi-directional fluid flow through the loudspeaker port to determine whether the representation of the bi-directional fluid flow through the loudspeaker is indicative of a port design where an exit flow separation occurs prior to an entrance flow separation; and if the representation of the bi-directional fluid flow through the loudspeaker port is not indicative of a port design where an exit flow separation occurs prior to an entrance flow separation, then redefining the at least one geometric associated with the loudspeaker port, and repeating the modeling, obtaining and analyzing steps until the representation of the bi-directional fluid flow through the loudspeaker port is indicative of a port design where an exit flow separation occurs prior to an entrance flow separation and optimizing the performance of the loudspeaker port by utilizing the at least one geometric that was redefined that resulted in the representation of the bi-directional fluid flow through the loudspeaker port where the exit flow separation occurred prior to the entrance flow separation.
