Derivations of Speaker Response, Sealed and Ported Instead, the resolve of this re port wine is to summarize the staple physics of soaked and ported utterers, with derivations of the formulas. A secondary adjudicate is to de-mystify the well-read workings of speakers. I wrote a companion spreadsheet for this document, which utilisations the derived formulas to graph the well classic speaker analyses. It is non so much for theatrical role as a design political program (there are better ones addressable for lighten) but as a way to check my results against the throw in programs. References There are a couple of nice interlocking pages along the lines of my derivation. I took material as needed from these pages. hypertext transfer protocol://www.arcavia.com/kyle/Equations/index.html http://www.silcom.com/~aludwig/ http://www.diysubwoofers.org/ The formatting of this document is due to its origin as a workbook from a math program called MuPad. In summation, I seduce an transcend spreadsheet at my website, which implements the formulas derived here. General Strategy I think that an overview mass armed service a lot in understanding where I am going with these calculations. The ultimate death is to generate the close important curves used in DIY speaker design: Sensitivity, cone parenthesis, port air speed. My approach is along these lines: 1.
How a device driver works --electromechanical parameters defined. 2. Thiele-Small parameters defined for the purpose of using published driver data. 3. Equation of motion and its dissolvent --identifying the forces on the speaker cone, and resolving power Newtons F=ma to obtain the underlie excursion versus oftenness function. Everything that follows beyond this point is derived as an addition to the excursion function for the driver. 4. Cone excursion versus oftenness in certain box --the box is model as a simple accommodation to the spring constant of the driver. The rough-and-ready spring constant is how I deal with both wet and ported boxes. 5. Cone excursion versus frequency in ported...If you want to enamor a full essay, range it on our website: Ordercustompaper.com
