Problems solved by technology

While this approach has some advantages in some ways, it overly restricts catheter design to only those shapes and configurations that can produce a constant pressure gradient
More importantly, this method does not take into account the real potential factors affecting boundary layer separation, and cannot fully optimize the acoustic performance for any given spatial confinement
[0012] While these methods can provide some improvements over previous sound systems, they do not take into account the true underlying factors that affect sound system performance

Abstract

A duct design and methods for designing ducts are described herein. The duct has a profile described by an equation that balances momentum of the fluid flowing through the duct with an adverse pressure gradient. The duct profile is configured to: (i) maintain the fluid's momentum to be greater than the adverse pressure gradient present at any location within the duct, such that no boundary layer separation occurs; and (ii) achieve a fluid exit momentum of approximately zero.

Description

[0001] This application claims priority to divisional application No. 61 / 506992 filed on July 12, 2011, which application is incorporated herein by reference. technical field [0002] The present invention relates to sound systems, and more particularly to conduits for audio transducer housings. Background technique [0003] In this section, information that is helpful for understanding the subject matter of the present invention is contained. It is not intended that any of the information provided herein is prior art or relevant to the present subject matter, or that any disclosure specifically or implicitly referenced is prior art. [0004] A transducer (i.e. loudspeaker) is a well-known device that typically includes a radiating surface (eg dome, diaphragm, membrane, cone, etc.) driven by a voice coil. Current is applied to the voice coil through the amplifier, thereby creating an electromagnetic field around the voice coil. The electromagnetic field interacts with the ...
