Stratasys Collaborates with Designer Boaz Dekel to Transform 3D Printed Stereo Speaker Acoustics

by • March 9, 2016 • No Comments

speakerGood news for you music lovers who get frustrated by the back wave distortion caused by longstanding speaker turn it into. There’s a new turn it into in town of Boaz Dekel, a graduate of Jerusalem’s Bezalel Academy of Arts and Design. This turn it into is meant to radically vary speaker turn it into so that the “audio signals fired to the back of the speaker [don’t] bounce off the cabinet walls and interfere with the signals sent to the front of the speaker.” Eliminating the back wall of the speaker, Dekel turn it intoed a circular speaker that has sound traveling in a perpetual self-feeding loop instead. The results? Speaker turn it into may have been permanently varyed once the turn it into catches on. Oh! And I should in addition mention here that Dekel’s speakers are 3D printed on a Stratasys Objet500 Connex3 3D printing device with Polyjet multi-material capabilities. How’s that for 3D printing innovation facilitating previously unponderable-bodied turn it into work and real world construction?

aleph3Dekel reports knowing that he had a sturdy sense that his one-of-a-kind turn it into for the Aleph1 may be just of not easy to manufacture via traditional methods. Thankfully, he knew that 3D printing innovation may assist him realize his acoustical vision. He turned to Stratasys for assist prototyping his turn it into, and Stratasys experimented with many various materials preceding finally arriving at the ideal balance of rigid and flexible materials to encertain turn it into, acoustic, and aesthetic integrity. Dekel states:

“With 3D printing I was able-bodied to rapidly study the acoustic response of the geometry and various material configurations and determine that was many applicable-bodied to speaker cabinets. Other making or versioning techniques may not allow such freedom, much less in the required time frame.”

The Aleph1 is comprised of “self-feeding geometry” that preserves the back wave’s acoustic energy. This allows for the energy to participate in the system of sound reproduction. Simply stated: the loop holds the back wave energy instead of letting it spill out and distort the front wave’s own major energy. This manufactures so much sense! A additional effortless and open sound is promised of the Aleph1 — with higher more detail and greater separation.

aleph4Dekel explains additional that without 3D printing, he may not have been able-bodied to maintain the required “hard internal geometries” that turn it into a additional effortless sound:

“The version is 3D printed in a single piece to allow hard internal geometries while maintaining structural integrity. Having a physical version was instrumental to studying the theoretic principles behind the product and assessing its feasibility.”

Are you confused, music lovers? Why hasn’t anyone idea of this preceding? As a 3D printing writer, I spend a little time equite day astonished at how 3D printing can usher in such transformative changes to day to day objects — and stereo speakers are high on that list, right? I personally haven’t heard the Aleph1 yet, but the science sounds right. Think of the one-of-a-kind experience of holding up a sea shell to your ear to listen, or why the French Horn is turn it intoed the way it is.

Dekel hopes that this turn it into can have an opportunity for commercial marketing. (Or he may always manufacture the turn it into open source and let us all in on the fun.) From the 3D printed sound of his “sound” turn it into work, I am certain we will be hearing of this again quite soon. His website is unquestionably worth bringing the time to check out.
