Passive Audio Amps For Smart Phones

Small Brass Horn — Wood Base

 

Cornucopia

This one has been made from a Horn of Plenty (an antique hammered-brass planter) that came from India.

 

Theseare acoustic amplifiers for smartphones. They don't need electric power to operate and there are no moving parts. They work like a megaphone (speaking-trumpet, bullhorn, blowhorn, or loudhailer). Everyone that I have shown it to has said something like “Wow, I want one of those!” So I am building a few of them.

Of course there are more “Hi-Fi” ways to listen to audio on your smartphone but who would want to plug an elegant smartphone into some cheap, plastic gadget? Or even use Wi-Fi or Bluetooth, which are a pain in the neck to set up, even on a smartphone.

These will be made with hardwood bases and some of them will be exotic hardwoods with interesting grain patterns. The horns are polished brass — made from mostly old horns that had rubber bulbs on the ends and were used in “times gone by” by taxis and even clowns in circuses. These horns have been re-purposed, reshaped, and re-polished.

Of course when not listening to music or other interesting audio, you can appreciate it for its beauty, it looks just plain cool. This is a work of art.

Sorry to say that I didn't design the first one on the left myself. It was designed by Daniel Jansson in Sweden. He is a graduate of Umeå Institute of Design with an MFA degree in Interactive Design.

 

If you see a horn that catches your fancy let me know and I will build an amp for you.
