“Hidden within one of Apple’s recent patent applications is a conceptual figure that Apple simply describes as an accessory device; a device that is clearly meant to enhance the value of an iPod – be it an iPod Classic or iPod touch,” Jack Purcher reports for MacNN.

“The contemplated accessory would add practical capabilities to the iPod, such as providing superior speakers and a built-in microphone that would work with Apple’s new iPod touch/iPhone voice memo app – which is great for consumers, students and professionals,” Purcher reports.

“The iPod accessory could also introduce other interesting twists such as adding the ability to introduce external data to the iPod via SIM cards, flash drives and even hard drives,” Purcher reports.
