iPhone Gramophone Amplifier

The Bone Horn Stand is an un-powered amplifier for the iPhone 4. Working just like the old-style horn-speakers found on gramophones, the silicon speaker slips over the iPhone’s end and channels the sound through the trumpet-shaped tube. This, according to the specifications, “adds 12 decibels of sound pressure to your iPhone’s speakers.”

The speaker also works as a stand, supporting the iPhone in horizontal or vertical orientation, and even has a nubbin that will pass your presses on to the home-button beneath. Available now, $25.
