Gramohorn II

A 3D-printed speaker that amplifies without electricity, inspired by an age-old design and created using modern technology

There's something of a divide in the design community when it comes to 3D printing. While some fully back the innovative and open-source abilities of the technology, others are afraid that it will detract from the individual character of design objects. Taking both sides of the coin into account, Justin Wolter, designer of the Gramohorn II—a non-electric speaker that amplifies sound from the HTC One smartphone naturally—is trying to change negative perceptions around 3D printing in the design world.

The inner workings of the speakers are inspired by the mechanics of age-old audio amplification equipment. The resonance chambers found in the device are designed specifically to enhance the audio output of the HTC One, paying special attention to bass notes and lower frequencies to provide a richer sound. To give a more personal touch to a 3D-printed piece, Wolter hand sands and finishes every printed Gramohorn. Once the run is complete, Wolter plans to delete the files; giving the Gramohorn II a limited feel, even if it was printed. The combination of human elements with cutting-edge manufacturing technology, as well as the mix of smartphone technology enhanced with a vintage design, makes this piece especially interesting from a macro perspective on the juxtaposition of old and new design. gramohorn-ii-3.jpg

At once a functional, high-design audio system as well as a piece of influential art in the academic trajectory of 3D printing, the Gramohorn II is available in a plaster-based composite material with a colored finish of your choosing for £1,000. Limited to just 10 pieces, the Gramohorn II is also available in a metal-based powder composite infused with brass and finished in one of three special metal coatings for £5,000.
