Speaker Design Theory and Calculations

Derivations of Speaker Response, Sealed and Ported Instead, the purpose of this report is to summarize the fasten physics of soaked and ported speakers, with derivations of the formulas. A secondary purpose is to de-mystify the versed workings of speakers. I wrote a companion spreadsheet for this document, which utilisations the derived formulas to graph the almost important speaker analyses. It is not so much for hire as a design program (there are break ones addressable for lighten) but as a way to apprehension my results against the free programs. References There are a couple of prissy meshing pages along the lines of my derivation. I took material as inevitable 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 ancestry as a workbook from a math program called MuPad. In addition, I s educe an Excel spreadsheet at my website, which implements the formulas derived here. General outline I think that an overview mass help a quite a little in understanding where I am going with these calculations. The net goal is to generate the close important curves used in DIY speaker design: Sensitivity, cone excursion, port air speed. My onset is along these lines: 1.

How a device driver works --electromechanical parameters specify. 2. Thiele-Small parameters defined for the purpose of using published driver data. 3. Equation of gesture and its solution --identifying the forces on the speaker cone, and resolving Newtons F=ma to obtain the underlying excursion versus absolute frequence operation. E! verything that follows beyond this point is derived as an addition to the excursion function for the driver. 4. Cone excursion versus frequency in sealed box seat --the box is modeled as a simple alteration to the spring constant of the driver. The effective spring constant is how I deal with both sealed and ported boxes. 5. Cone excursion versus frequency in ported...If you want to get a full essay, ruckle it on our website: OrderEssay.net
