Here’s something you don’t see everyday. The Bone Horn Stand uses old technology to enhance modern technology. It’s an un-powered amplifier for the iPhone 4, that works exactly like those old style horn speakers on gramophones. The speaker fits over the end of the iPhone where the built in speakers are.
Then the sound is channeled through the horn, and it supposedly adds 12 decibels of sound pressure to your iPhone’s built in speakers. The device can also be used as a stand.
