What it does

  • A cone shape that flares from a narrow throat to a wide mouth
  • Sized with a small opening to fit against a phone speaker
  • Set on a flat base, so it can sit upright on a desk or shelf
  • Made to order in the USA after you place your order
  • A display piece for anyone curious about horn acoustics

Music lovers and tinkerers who like small desk gadgets will notice this horn's swept, flaring shape right away. It is modeled with an exponential profile, curving outward from a narrow throat to a wide open mouth, the same basic shape used in old phonograph horns and early speaker design.

The narrow end is shaped to sit near a cellphone speaker, and the wide mouth opens outward from there. Its curved body has a smooth, continuous line from end to end, giving it a look you would expect from a classic horn amplifier.

This piece works well as a desk accessory or a conversation piece for anyone interested in acoustics, sound design, or vintage-style audio gear. Each one is made to order in the USA after you place your order.

2.7k downloads in the maker community. That is interest in the design on the site it came from, not our sales.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
