Print media with inductive secondary
An item of print media ( 30 ) including an inductive secondary ( 50 ) for providing power to a load ( 32 ). The inductive secondary is responsive to an electromagnetic flux to generate a time-varying current or voltage therein. The current or voltage induced in the inductive secondary directly or indirectly powers the load to thereby enhance the functionality and/or the appeal of the item of print media without significantly adding to its cost. The load can provide a visual and/or auditory output, and can include an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED or an LCD display. Embodiments of the invention can be utilized in connection with a wide variety of print media, including for example books, booklets, pamphlets, labels, magazines, manuals, brochures, maps, charts, posters, journals, newspapers or loose leaf pages.
1. An item of print media comprising:
a first substrate including textual or graphic content thereon; and
an inductive secondary supported by the first substrate, wherein the inductive secondary is operable to drive a visual, olfactory, or auditory device in response to a time-varying electromagnetic field to enhance the textual or graphic content.
2. The item of print media of claim 1 , wherein the inductive secondary includes one of a wire coil and a PCB coil.
3. The item of print media of claim 1 , wherein the first substrate includes one of a page, a label, a cover, a jacket, a binding, a spine and a sleeve.
4. The item of print media of claim 1 further including a second substrate including a display area and supporting the visual or auditory device thereon.
5. The item of print media of claim 4 wherein the first and second substrates are joined along a fold line.
6. The item of print media of claim 1 wherein the visual or auditory device includes at least one of an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED and an LCD display.
