Want a little something to help boost your iPhone’s audio level, but don’t want a fancy gadget? Perhaps the Bone Horn Stand might be what you’ve been searching for. This device is a non-powered amplifier for the iPhone 4, functioning just like those old-fashioned horn-speakers on gramophones. It’s a silicon case that slips over the iPhone’s bottom half, channeling the sound through the trumpet shaped tube, apparently adding 12 decibels of sound to your iPhone’s speakers. It can also double up as a stand, allowing your iPhone to stand in horizontal or vertical orientation. It’s currently available and will set you back $25.
