Well I am going public on a little project of mine. It is an open source project so please join me or feel free to share it with anyone who you think would be interested in it. A little information. This is a spherical speaker enclosure. The shape allows the sound energy to project ahead/around the speaker with a nice smooth diffraction loss curve. Further, it is a ported speaker to help boost low frequency tones that small 3" speakers typically have a hard time reproducing. To minimize resonance in the enclosure/port tubes I have smoothed all the pathways to prevent edges and surfaces for sound to reflect off. Eliminating these resonance effects again allows the speaker to accurately reproduce sounds without accidentally exaggerating or muting specific notes/tones. To aid in port tuning, the speaker has a decreasing radius spiral that acts very much like the cochlea in your ear. High frequency sounds have a very difficult time bending around corners, so the spiral acts as a filter to remove these tones from exiting the port. Finally, since little speakers need all the help they can get. All of the port pathways have an increasing radius spiral that doubles as a horn to amplify the remaining bass tones. All of this in a tiny 7" diameter ball! As I mentioned this project is open source. If you want access to the file I used to print the speaker below, it is free and can be found in the link below. https://www.thingiverse.com/thing:2398268 If you want access to a revised file which relocates the tubes a little farther apart to reduce the chance of the port tubes being connected as well as an added notch for running internal wiring. You can find this file in the link below for $20 USD. All you need then is a printer or acess to one and you can then print as many as you like. https://www.turbosquid.com/3d-models/speaker-bass-3d-1170521 Finally, if you have no idea what to do with an stl file but would still like to order the enclosure(s) shipped to your door. I have a shapeways link. They don't do hollow/infill shapes so the build will be very solid/premium. However that comes at the tradeoff of added cost. https://www.shapeways.com/product/875ZUKL9E/bass-ball… I eventually want to produce these speakers but I am in need of a little extra cash flow to help cover the costs of prototyping. Which is part of the reason why I opened this project up. The other reason is because I would like additional subjective input on their design. If anyone has any opinions, feel free to ask. And please, share this with anyone you know who loves awesome sound.
