This acoustic speaker was engineered to amplify music up to 4 times without using batteries. Simply dock your iPhone 4 or 4S into this ingeniously designed, silicone-molded portable speaker and it will amplify the sound up to 4 times. Compact and light, take with you on the go. Ideal for outdoors, patios / porches, picnics, or even in a car not equipped with iPhone inputs or Bluetooth.

utterly ineffective
I measured the volume with this mechanical speaker (ie, no electronics -- it's like holding your hands to your mouth to amplify your voice) and without. It made a whopping FOUR-DECIBEL DIFFERENCE. Um, no thanks.
