主题：怎样估算喇叭频响曲线

不是用FINECONE,liuxiaojun 教授相信水仙認識吧,他讀碩士的時侯Peterlansing 或許還在JBL,dynaudio做工程師呢!我說的是liu教授自已用電腦編的軟件,計算出來的結果與實際比較我親眼見過.

国内用有限元分析计算的确实比较早，前几天偶然看到同学的一篇早年论文就是用有限元方法分析失真和分割振动的。

例子中就有！

有人可以,我见过.台湾人~~~

不会吧，您是指摸一下纸盆就知道曲线走势。

见过韩国人听过频响曲线后,直接大概画出来的.

听过频响曲线后,直接大概画出来的

这是可能的！

使用ANSYS算B值,然后使用MATLAB估算曲线

只有B值就能估算曲线?

What Is MATLAB?
MATLAB® is a high-performance language for technical computing. It integrates computation, visualization, and
programming in an easy-to-use environment where problems and solutions are expressed in familiar
mathematical notation. Typical uses include:

Math and computation
Algorithm development
Modeling, simulation, and prototyping
Data analysis, exploration, and visualization
Scientific and engineering graphics
Application development, including graphical user interface building

MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This
allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a
fraction of the time it would take to write a program in a scalar noninteractive language such as C or Fortran.

The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix
software developed by the LINPACK and EISPACK projects. Today, MATLAB uses software developed by the
LAPACK and ARPACK projects, which together represent the state-of-the-art in software for matrix computation.

MATLAB has evolved over a period of years with input from many users. In university environments, it is the
standard instructional tool for introductory and advanced courses in mathematics, engineering, and science. In
industry, MATLAB is the tool of choice for high-productivity research, development, and analysis.

MATLAB features a family of application-specific solutions called toolboxes. Very important to most users of
MATLAB, toolboxes allow you to learn and apply specialized technology. Toolboxes are comprehensive
collections of MATLAB functions (M-files) that extend the MATLAB environment to solve particular classes of
problems. Areas in which toolboxes are available include signal processing, control systems, neural networks,
fuzzy logic, wavelets, simulation, and many others.

这次讲座会讲到PSPICE仿真

哇噻，原来做喇叭可以做到这样厉害呀

羡幕

还是水仙厉害。用FINECONE，不过有厉害的人。经过触摸材料与听音可以判定扬声器的频响曲线的结果，和仪器测试出来相差不大，这可能是经验的积累吧！不过不是我啊！

可以用一个小的软件模拟来出来！！

是啥软件？

听说惠州有位大师能跟据音乐信号去画频响，不知是否真实，

有听过这样的牛人．０.５dＢ的差别都可以听出来，而且什么频率段都听得很准确

.

聽說ansys可以模擬!
