Apple has just introduced their new iPod touch with an HD cam for both video and point and shoot style stills and according to a new patent application published this morning by the US Patent and Trademark Office, they're already working on a new zoom lens accessory. While the patent presents several methods of attaching a zoom lens to a media player like the iPod touch, the main focus is on utilizing an advanced magnet array coupling approach that could actually be personalized to reduce the risk of theft. Other accessories using this technique could include mini speakers or another kind of microphone. Just the mere idea of Apple introducing advanced zoom lenses for their leading world class media players has got to have competing camera OEMs choking on their morning coffee.
Optical Accessory for Media Players
According to Apple's patent, a user will be able to enhance the functionality of a media player by connecting one or more accessories to it. Different approaches could be used to couple the accessory to an electronic device. For example, one or more mechanical fasteners, clips, adhesives, hook and fastener material (e.g., Velcro), latches, bands, or other fasteners could be used to connect the accessory to the electronic device.
Apple's patent FIG. 2 shown below is a schematic view of an optical accessory coupled to a media player. The media player 200 could include housing 202 to which optical accessory 210 could be coupled. The accessory could be positioned at any suitable position on the housing, including for example, opposite an internal camera lens of the media player, such that the accessory complements or enhances the functionality of the internal camera lens.
To retain the accessory in place, clips 212 could be placed around the housing (e.g., around at least one edge of the housing). The shape, length and specific positioning of the clips could be selected based on the specific accessory, the shape of the housing, and the desired or required position of the accessory on the media player.
Some accessories could require specific alignment with the media player. For example, the accessory could operate only when properly aligned with a camera lens of the media player. It may be difficult, however, to properly position the accessory if the housing has an irregular shape (e.g., curved surfaces) as the accessory could slip or slide, or not extend from the housing from a proper angle (e.g., orthogonal relative to the camera lens). In addition, the shape of the media player and the housing may make the use of clips or other mechanical fasteners difficult (e.g., curve surfaces not optimized for receiving clips, or accessory devices positioned at a distance from edges of the device).
Magnet Array Coupling
As an alternative or smarter approach for at least aligning an accessory to the media player, a magnet array could be used. Apple's patent FIG. 3 shown below is a broad schematic view of a media player and an accessory coupled using an illustrative magnet array. Media player 300 could include port 302 in housing 301. The port could include an opening in the housing through which one or more interfaces could provide or receive information. For example, port 302 could provide an opening for a camera lens, an electronic connector (e.g., a 30-pin or a USB connector), audio output circuitry (e.g., speakers), a sensing mechanism, or any other suitable interface. Accessory 310 could be positioned over the port to enhance the use or features of the interface positioned within the port.
To align the accessory precisely around the port, first magnet array 304 could be positioned around the periphery of the port. The magnet array could include any suitable number of magnets oriented in any suitable manner. For example, the magnet array could include at least one magnet for aligning accessory 310 relative to port 302. As another example, the magnet array could include several magnets for ensuring a reduced number of orientations of the accessory relative to the housing.
To ensure that the accessory is properly coupled to the housing, the accessory could include a second magnet array 312. The magnets of magnet array 312 could be positioned such that the magnets of the magnet array are lined up with the magnets of magnet array 302 when the accessory is properly positioned and aligned relative to the housing 301. The polarity of the magnets of the magnet array could be selected and distributed to be opposite those of magnet array 302. By appropriately selecting one or both of the physical distribution and polarity of the magnets in each magnet array, a user could ensure that only a single orientation of the accessory allows the magnets of one array to be positioned opposite an opposing magnet of the other array.
The polarity of the magnets of magnet arrays could vary in any suitable manner as illustrated above in patent figures 4A and 4B.
Personalized Magnet Array
Because some accessories or media players could be expensive, a user may wish to personalize one or both of the media player and accessory to reduce the risk of theft. In particular, a user may wish to define a personalized magnet array such that accessories authorized accessories to work with the user's media player may not properly couple or be aligned with unauthorized media player. The user could personalize the magnet array of the electronic device using any suitable approach.
In some embodiments, a user could define the polarity of one or more magnets of the array. For example, a user could select the direction of current for one or more electromagnets to set the polarity of the electromagnets. As another example, a user could mechanically flip one or more permanent magnets (e.g., using an appropriate setup mechanism embedded within or external to the media player).
In some embodiments, a user could instead or in addition define the physical distribution of magnets within the magnet array. Apple's patent FIG. 5 noted above is a schematic view of an illustrative magnet array that could be personalized. Magnet array 500 could be positioned around the periphery of port 502. To allow the user to change the physical distribution of magnets, the array could include first set 510 of magnets and second set 520 of magnets, where the magnets of each of sets 510 and 520 are positioned at different distances from the center of the port. The user could personalize the magnet distribution by moving one or more magnets from each of sets 510 and 520. For example, the user could select individual magnets to displace.

Duplex Audio for Mobile Communication Device and Accessory: Duplex audio is provided for the iPhone and an accessory (shown to be a boombox). The accessory could selectively operate in a duplex audio moe, concurrently sending audio to and receiving audio from the iPhone, or in another audio mode. In duplex audio mode, the accessory could enable its internal audio processing operations (e.g. echo cancelation) while the iPhone disables its corresponding internal operations or vice versa.

Audio Preview of Music: Apple's patent is about providing an audio preview of songs and other audio elements. An iPod could provide a user-controllable pointer scrollable through various categories, such as different genres or artists. Responsive to each movement of the pointer, the iPod could select a song from the pointed-to category and could play a portion of the selected song. In other embodiments, music groups could be defined, where each music group includes sons that go well together. The iPod cold play, in succession, a portion of one song from each of the music groups. Responsive to a user selection of a playiing portion, the iPod could create a playlist based on the music group of the selected playing portion. For more information, see patent 20100229094.
