  • Display with wave generators
    Patent number: 8885862
    Abstract: In one embodiment, a kit for making a display includes a first medium, a support element, and first and second wave generators. The first medium is foldable according to scoring to form a display with a cavity. The element is attachable or attached to a back surface of the folded first medium, to be positioned at least partially within the cavity. The first wave generator is attachable or attached to the back surface, to receive signals from a signal generator and produce mechanical waves that cause the first medium to vibrate and generate audible acoustic waves within a first frequency range. The second wave generator is attachable or attached to the element, to receive signals from the signal generator and produce mechanical waves that cause the element to vibrate and generate audible acoustic waves within a second frequency range, different from the first frequency range.
