ReAcoustic's iPhone and iPad docks rely on nothing but a wooden base and antique gramophone amplification horns, trumpet bells, and the like to pump up the sound.
ReAcoustic double dock
Ryan Boase's ReAcoustic iPhone and iPad docks consist of a base of reclaimed wood and a salvaged antique amplification horn of some kind--from a gramophone, a trumpet, or perhaps even a trombone. Oh, and a long tunnel-like hole that runs from the smart-gadget's speaker to the base of the horn. That's it. It's an all-acoustic way to crank up tunes or other sound from the iDevice of choice.
With this particular double-dock, both an iPad and an iPhone can keep the gramophone horn company.
A tunnel-like hole runs from the iDevice's speaker to the base of the horn. You can see that hole here. You can also see the handmade quality of the wooden base. The somewhat rough-hewn look of the actual dock may make sense with the aged gramophone horns and brass instruments used. As ReAcoustic's Boase says, "The dents and scrapes add to the charm and character of [a horn], as you can tell it's lived a full life."
