Chicago-based company Gramovox has merged the old with the new in its Bluetooth Gramophone. The fusion of vintage audio device and modern technology takes the form of a 3:4 scale replica of the R3 Magnavox horn speaker and packs a Bluetooth 3.0 module to allow wireless connection of mobile devices.
Drawing inspiration for the S-curve horn from the 1920s-era R3 Magnavox, Gramovox CEO Pavan Bapu used stereolithography (SLA) to 3D print a prototype of the horn. However, the production horns will be made of steel and brass and hand-welded to a base made of walnut or maple sourced from an Ohio lumber yard.
An inner cavity in the base houses an audio driver and a custom-printed circuit board (PCB) optimized for the acoustics of the Gramovox.
