This post is just a small one; I was playing around with acoustic topology optimization, and inspired by the Acoustic Demultiplexor, I had an idea about having two inputs, each of them assigned to each their output, without any explicit 'tubing' being possible for this 2D case. At one input a certai...

I have for the past couple of years tried to push the development of Microacoustics Optimization (especially Topology Optimization) and get more focus on its research and engineering development. Even though it is still very much an unexplored topic, there has been work done with Microacoustics and...

In previous posts (#006 and #008) I have shown how you can make virtual prototypes for loudspeaker drivers. Now, I have also made a tweeter. This geometry can be used for investigating the effect of e.g. ferrofluids, porous materials, former holes, and opening up or closing off the air volume behind...

Today we will have a look at an acoustic design that I have been wanting to do for a long time; the Acoustic Demultiplexor.

The acoustic Demultiplexor is a device that can split an input into several outputs based on the frequency content of the input signal. Here, it has three different geometrical...
