Title: Accessory cover for a portable electronic device

Abstract:
An accessory device for a portable electronic device is described. The accessory device includes a front cover connected to a back cover. The front cover includes multiple segments rotatable with respect to each other. The segments include magnets that allow the segments, through magnetic coupling, to couple with another segment or with the portable electronic device. When the front cover engages the back cover, a user may remove, or pull away, a segment from the back cover, causing the remaining segments to sequentially fall away from the back cover. In some instances, when the front cover at least partially engages the back cover, one of the segments includes magnets designed to couple with magnets in the back cover, but not with magnets in another segment. The accessory device may further include an opening that receives a camera assembly of the portable electronic device and forms a mechanical interlock.

     Those skilled in the art will appreciate and understand that, according to common practice, various features of the drawings discussed below are not necessarily drawn to scale, and that dimensions of various features and elements of the drawings may be expanded or reduced to more clearly illustrate the embodiments of the present invention described herein. 
     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments. 
     The following disclosure relates to accessory devices for use with portable electronic devices, such as mobile wireless communication devices and tablet computer devices. Accessory devices described herein may be referred to as covers, cases, protective covers, protective cases, or folios, as non-limiting examples. Accessory devices are designed to house and protect portable electronic devices. In this regard, accessory devices herein may cover both the transparent cover (or cover glass) positioned over the display assembly of the portable electronic device as well as the housing of the electronic device. As a result, an accessory device described herein may provide protection against damage to a portable electronic device. 
     An accessory device may include a back cover (also referred to as a first section or back panel) attached to a front cover (also referred to as a second section or front panel) by a hinge. The front cover can cover the transparent cover of the portable electronic device, while the back cover can at least partially cover the housing of the electronic device. The front cover may include multiple segments that are rotatable with respect to each other. At least some of the segments may include magnets that allow the segments to couple, or secure, with each other (through magnetic coupling) as well as with the portable electronic device (through magnetic coupling with magnets in the portable electronic device). Further, when the segments couple with each other, the front cover may fold and form a support, or stand, for the portable electronic device. 
     The back cover may provide a receiving surface for the electronic device. Also, the back cover may include several magnets designed to magnetically couple with magnets in the portable electronic device. Further, at least some magnets in the front cover may magnetically couple with magnets in the back cover. This allows for a configuration of the accessory device in which the front cover is stored behind the back cover. As a result, the accessory device provides a compact design with a reduced footprint. Also, prior to the front cover lying flat against the back cover (and while an air pocket separates the front cover from the back cover), some magnets in the front cover may magnetically couple with magnets in the back cover. In this manner, the magnetic coupling may provide a force that shifts, or moves, the front cover and aligns the front cover with the back cover. This allows the hinge that couples the front cover to the back cover to provide additional flexibility, as the magnetic coupling can align the front and back covers with each other. 
     These and other embodiments are discussed below with reference to  FIGS. 1-20 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1  illustrates an isometric view of an embodiment of an accessory device  100 , in accordance with some described embodiments. The accessory device  100  is designed for use with an electronic device  180 , including portable electronic devices such as mobile wireless communication devices and tablet computer devices. In this regard, the accessory device  100  may be referred to as a case, a cover, a protective cover, a protective case, a folio, or the like. 
     As shown, the accessory device  100  may include a first section  102   a  coupled to a second section  102   b . The first section  102   a  may define a back cover or back panel for the electronic device  180 . Also, the first section  102   a  may define a receiving surface  104  that receives the electronic device  180 , and in particular, a housing  182  of the electronic device  180 . In this regard, the first section  102   a  may retain the electronic device  180  with one or more magnets embedded in the first section  102   a . This will be shown and discussed below. The first section  102   a  may further include an opening  106 , or through hole, designed to receive a camera assembly  184  and a flash module  185  (both shown as dotted lines) of the electronic device  180 . 
     The second section  102   b  is designed to wrap around and cover the electronic device  180 , including a display  186  of the electronic device  180 . In this manner, the second section  102   b  may be referred to as a front panel or front cover. The second section  102   b  may include multiple segments. For example, the second section  102   b  may include a first segment  108   a , a second segment  108   b , and a third segment  108   c . Each segment is rotatable or moveable with respect to the remaining segments. Also, while a discrete number of segments are shown, the number of segments may vary in other embodiments. 
     The second section  102   b  is coupled to the first section  102   a  by a hinge  112  such that the first section  102   a  is rotatable with respect to the second section  102   b , and vice versa. The hinge  112  may be formed in part by one more continuous pieces of material that extend along the first section  102   a  and the second section  102   b . The materials that form the layer(s) may include polymers, such as polyurethane, that wrap around a fiberglass material. Other materials, such as leather, are possible. However, in order to promote flexibility and relative movement of the aforementioned sections and segments, the fiberglass material (and/or other relatively rigid or stiff materials) may not be located at the hinge  112  and may not be located between the segments. This will be shown and described below. Also, a soft, non-abrasive material, such as microfiber, may cover the first segment  108   a , the second segment  108   b , and the third segment  108   c . In this manner, when the second section  102   b  wraps around and covers the display  186  (which may include transparent cover overlaying the display  186 ), the soft, non-abrasive material does not cause damage when in contact with the transparent cover. 
       FIG. 2  illustrates a plan view of the accessory device  100  shown in  FIG. 1 , showing a layout of magnets in the accessory device  100 . The magnets (or magnetic elements) described herein may include permanent magnets, ferromagnetic materials, rear Earth magnets, or other magnetically attractable materials. As shown, the accessory device  100  may include magnetic elements  114   a , magnetic elements  114   b , magnetic elements  114   c , and magnetic elements  114   d  located in the first section  102   a . The magnetic elements  114   a , the magnetic elements  114   b , the magnetic elements  114   c , and the magnetic elements  114   d  are designed to magnetically couple with magnets in the electronic device  180  (shown in  FIG. 1 ) to retain the electronic device  180  with the receiving surface  104 . As a result, the accessory device  100  does not require mechanical features (such as retaining walls, sidewalls, or mechanical interlocks) to retain the electronic device  180 . Furthermore, the magnetic elements in the accessory device  100  that magnetically couple with magnets in the electronic device  180  provide a magnetic attraction force capable of holding the electronic device  180  even when forces, such as gravitational force, are acting on the electronic device  180  that would otherwise cause the electronic device  180  to detach from the accessory device  100 . 
     Some magnetic elements (shown as dotted lines) shown and described in  FIG. 2  may include several discrete magnetic elements. For example, as shown in the enlarged view, the magnetic elements  114   a  includes six discrete magnetic elements. The number of magnetic elements may vary in other embodiments. By using several, smaller discrete magnetic elements, as opposed to using fewer, but larger magnetic elements, the ease of aligning the electronic device  180  (shown in  FIG. 1 ) with the first section  102   a  increases. For example, each magnetic element provides a relatively small external magnetic field (not shown in  FIG. 2 ), thereby reducing the magnetic attraction force per magnetic element during the alignment. However, the magnetic elements, as a group (such as the cluster of the magnetic elements  114   a ), may provide a similar collective external magnetic field as that of a single, larger magnetic element. As a result, the magnetic attraction force of the group of magnetic elements is similar to that of a single, larger magnetic element, while the ease of alignment is increased, as compared to the use of the single, larger magnetic element. 
     The accessory device  100  may further include magnetic elements  114   e , magnetic elements  114   f , and magnetic elements  114   g  in the first section  102   a  that are designed to magnetically couple with magnetic elements  114   h , magnetic elements  114   i , and magnetic elements  114   j , respectively, in the second section  102   b . These magnetic couplings may occur when, for example, a back surface (not shown in  FIG. 2 ) of the second section  102   b  is rotated over and onto a back surface (not shown in  FIG. 2 ) of the first section  102   a  via the hinge  112 , with the back surface of the first section  102   a  being opposite the receiving surface  104 . Also, these magnetic couplings may occur when the second section  102   b  is rotated over and onto the receiving surface  104 . 
     The accessory device  100  may further include magnetic elements  114   k  and magnetic elements  114   l  located in the first section  102   a  that are designed to magnetically couple with magnetic elements  114   m  and magnetic elements  114   n , respectively, located in the second section  102   b , and in particular, the second segment  108   b . The magnetic elements  114   m  and the magnetic elements  114   n  are parallel (or aligned) with each other, while the magnetic elements  114   k  are offset (or misaligned) with respect to the magnetic elements  114   l . Also, when the aforementioned back surfaces of the first section  102   a  and the second section  102   b  are engaged with each other, the magnetic elements  114   k  and the magnetic elements  114   l  are offset with respect to the magnetic elements  114   m  and the magnetic elements  114   n , respectively. However, the degree of offset between the magnetic elements  114   k  and the magnetic elements  114   m  may differ from that of the magnetic elements  114   l  and the magnetic elements  114   n . In this manner, when the back surface of the second section  102   b  is positioned against the back surface of the first section  102   a , the magnetic attraction between the magnetic elements  114   k  and the magnetic elements  114   m  may differ from the magnetic attraction between the magnetic elements  114   k  and the magnetic elements  114   m . For example, the magnetic attraction between the magnetic elements  114   k  and the magnetic elements  114   m  may be greater than the magnetic attraction between the magnetic elements  114   k  and the magnetic elements  114   m . As a result, when the magnetic elements  114   k  are no longer coupled to the magnetic elements  114   m , the magnetic elements  114   l  are no longer coupled to the magnetic elements  114   n . This may be part of a comprehensive process in which a removal of the first segment  108   a  from the back surface of the first section  102   a  initiates a subsequent removal the second segment  108   b  and the third segment  108   c  from the back surface of the first section  102   a  without any additional force required other than the force required to pull the first segment  108   a  away from the back surface of the first section  102   a . In other words, when the first segment  108   a  is removed from the back surface, the second segment  108   b  and the third segment  108   c  may automatically fall away from the back surface of the first section  102   a . This will be shown and described later. 
     The accessory device  100  may further include magnetic elements  114   o  located in the first section  102   a  that are designed to magnetically couple with magnetic elements  114   p  located in the second section  102   b , and in particular, the third segment  108   c . When the second section  102   b  is positioned against the back surface of the first section  102   a , the magnetic elements  114   o  magnetically couple with magnetic elements  114   p . Further, while the second section  102   b  is rotated over and onto the back surface of the first section  102   a , the magnetic elements  114   p  magnetically couple with the that magnetic elements  114   o  prior to the second section  102   b  fully lying on the back surface of the first section  102   a . The magnetic coupling can provide a magnetic attraction force that pulls the second section  102   b  in a manner that aligns the second section  102   b  with the back surface to prevent misalignment between the second section  102   b  and the first section  102   a . In other words, the second section  102   b  will not be crooked with respect to the first section  102   a  as a result of the magnetic coupling between the magnetic elements  114   o  and the magnetic elements  114   p . This will be further detailed below. 
     Also, the accessory device  100  may include a reinforcement layer  115  positioned in the first section  102   a  around the opening  106 . The reinforcement layer  115  may provide additional rigidity to a void or space that defines the opening  106 . This may prevent the first section  102   a  from breaking along the corner in which the reinforcement layer  115  is located. In some embodiments, the reinforcement layer  115  includes a glass fiber material having a relatively high density. However, other materials (such as metals, rigid plastics, as non-limiting examples) are possible. Further, the first section  102   a , and in particular, the receiving surface  104 , is generally planar. However, in some instances, the first section  102   a  may include a localized thickness in a location corresponding to the opening  106 , due in part to a thicker reinforcement layer, as compared to the reinforcement layer  115  shown in  FIG. 2 . 
     The accessory device  100  may include certain dimensional characteristics. For example, the hinge  112  may include a dimension  116   a  that the same as, or at least substantially similar to, a major dimension of the electronic device  180 . The “major dimension” may refer to a dimension of greatest length of the electronic device  180 . Also, the dimensions of some of the segments may differ. For example, the first segment  108   a  may include a dimension  118   a  that is less than a dimension  118   b  of the second segment  108   b  and less than a dimension  118   c  of the third segment  108   c . Further, the dimension  118   b  of the second segment  108   b  can be the same as, or at least substantially similar, to the dimension  118   c  of the third segment  108   c . However, other dimensional relationships of the first segment  108   a , the second segment  108   b , and/or the third segment  108   c  are possible. 
     Additionally, the accessory device  100  may include magnetic elements  114   q , magnetic elements  114   r , and magnetic elements  114   s  embedded in the first section  102   a . In some instances, when the first segment  108   a  is engaged with the second segment  108   b , the magnetic elements  114   h , the magnetic elements  114   i , and the magnetic elements  114   j  can magnetically couple with the magnetic elements  114   q , the magnetic elements  114   r , and the magnetic elements  114   s , respectively. This will be shown below. 
       FIG. 3  illustrates a cross sectional view of the accessory device  100  shown in  FIG. 2 , taken across line  3 - 3 , showing various features of the accessory device  100 . The accessory device  100  may include a first layer  122   a  and a second layer  122   b . The first layer  122   a  and the second layer  122   b  may include a polymer layer that extends across both the first section  102   a  and the second section  102   b  (shown in  FIGS. 1 and 2 ). Alternatively, each of the first layer  122   a  and the second layer  122   b  may include other materials, such as leather. In this regard, the first layer  122   a  and the second layer  122   b  may define the hinge  112  (shown in  FIGS. 1 and 2 ). The accessory device  100  may further include a third layer  122   c  that is surrounded by the first layer  122   a  and the second layer  122   b . The third layer  122   c  may include a relatively rigid material, such as fiberglass (as a non-limiting example). The third layer  122   c  may fill each of the segments. For example, as shown, the third layer  122   c  fills the first segment  108   a . However, the third layer  122   c  may be confined to the first segment  108   a  to promote flexibility of the second section  102   b  (shown in  FIGS. 1 and 2 ) and relative movement among the segments. Also, although not shown, the first layer  122   a  and the second layer  122   b  may terminate along the second section  102   b  and additional layers (similar to that of the first layer  122   a  and the second layer  122   b ) may form the first section  102   a . In this regard, the hinge  112  (shown in  FIGS. 1 and 2 ) may be formed from a material other than the first layer  122   a  and the second layer  122   b.    
     The accessory device  100  may further include a layer on each of the segments. For example, the first segment  108   a  includes a layer  124   a . The layer  124   a  may include a fabric layer, including microfiber. Generally, the layer  124   a  may include a material that prevents scratching of glass (or other transparent cover or transparent layer) of the electronic device  180  (shown in  FIG. 1 ). In order to promote flexibility, the layer  124   a  may terminate at (or may be confined to) the first segment  108   a . Further, the layer  124   a  can be applied to an uppermost (flat) surface of the first segment  108   a , as well as a portion of the bends (along the first layer  122   a ) that surround the uppermost surface. In some instances, the layer  124   a  extends along a surface that is generally perpendicular to the uppermost surface. However, the layer  124   a  may terminate prior to reaching an additional surface that is parallel, or at least substantially parallel, to the uppermost surface. Generally, the layer  124   a  may extend between a first line  126   a  and a second line  126   b , shown at each end of the first segment  108   a . It should be noted that the second segment  108   b  and the third segment  108   c  (both shown in  FIGS. 1 and 2 ) may include the same layers, including the same features and configurations of the layers, as shown for the first segment  108   a . For example, a layer  124   b  (separate from the layer  124   a ) is positioned on the second segment  108   b.    
     The accessory device  100  may further include a stiffening element  128  positioned between the first layer  122   a  and the second layer  122   b . The stiffening element  128  may include glass fiber, a rigid plastic, or a metal, as non-limiting examples. The accessory device  100  may further include an adhesive  132   a  and an adhesive  132   b  that secure the first layer  122   a  with the second layer  122   b.    
       FIG. 4  illustrates a side view of the accessory device  100 , showing the second section  102   b  partially positioned over the back surface  134  of the first section  102   a . It may desirable to configure the accessory device  100  such that a back surface  136  of the second section  102   b  lies flat against the back surface  134  (opposite the receiving surface  104 ) of the first section  102   a , as this configuration provides a more compact device. 
     Due in part to the hinge  112  having minimal, if any, stiffening elements and/or adhesives, the hinge  112  is relatively flexible but may allow misalignment of the second section  102   b  with respect to the first section  102   a . For example,  FIG. 5  illustrates a plan view of the accessory device  100  shown in  FIG. 4 , showing the second section  102   b  partially aligned with the first section  102   a . As shown, the edges of the second section  102   b  are not aligned with the edges of the first section  102   a . Without any other force(s) acting on the second section  102   b , the second section  102   b  may be crooked when the second section  102   b  lies on the back surface  134 . However, the magnetic elements  114   o  in the first section  102   a  can magnetically couple with the magnetic elements  114   p  in the second section  102   b . The magnetic coupling provides a magnetic attraction force capable of pulling the magnetic elements  114   p  in the second section  102   b  toward the magnetic elements  114   o  in the first section  102   a.    
     The pulling force caused by the magnet attraction between the aforementioned magnetic elements causes the second section  102   b  to align with the first section  102   a  in a more desired manner. For example,  FIG. 6  illustrates a side view of the accessory device  100 , showing the second section  102   b  positioned over, and engaged with, the back surface  134  of the first section  102   a . The back surface of the second section  102   b  may lie on the back surface  134  of the first section  102   a  such that the back surface  134  of the first section  102   a  (including the edges) is covered by the second section  102   b . It should be noted that once the second section  102   b  and the first section  102   a  are aligned, the accessory device  100  may be rotated 180 degrees such that the second section  102   b  is positioned on a surface (not shown), such as a desk or table. In this manner, the electronic device  180  (shown in  FIG. 1 ) may be positioned on the receiving surface  104  of the first section  102   a.    
       FIG. 7  illustrates a plan view of the accessory device  100  shown in  FIG. 6 , showing the second section  102   b  aligned with the first section  102   a . As shown, the second section  102   b  is positioned over the back surface  134  of the first section  102   a  (both labeled in  FIG. 6 ).  FIG. 7  represents an aligned configuration between the first section  102   a  and the second section  102   b . In the aligned configuration, each corner of the first section  102   a  covers a respective corner of the second section  102   b  such that in the plan view (shown in  FIG. 7 ) the first section  102   a  covers the second section  102   b . Alternatively, the aligned configuration may also include each corner of the second section  102   b  (not shown in  FIG. 7 ) covering a respective corner of the first section  102   a  such that in an alternate plan view the second section  102   b  covers the first section  102   a.    
     Referring again to  FIGS. 4 and 5 , as the second section  102   b  is folded over the back surface  134  of the first section  102   a , the second section  102   b  may momentarily lie on ambient air (such as an air blanket). This allows the magnetic elements  114   o  in the first section  102   a  to magnetically couple with the magnetic elements  114   p  in the second section  102   b  prior to the second section  102   b  engaging the first section  102   a . However, in some instances, the second section  102   b  may partially engage the first section  102   a  prior to the magnetic coupling between the magnetic elements  114   o  and the magnetic elements  114   p . Nonetheless, the magnetic attraction force between the magnetic elements  114   o  and the magnetic elements  114   p  is capable of aligning the second section  102   b  with the first section  102   a , as shown in  FIGS. 6 and 7 . 
       FIG. 8  illustrates a side view of the accessory device  100 , showing the first segment  108   a  of the second section  102   b  pulled away from the back surface  134  of the first section  102   a . As shown, a pulling force can be applied to the second section  102   b  that overcomes magnet attraction force formed by the magnetic coupling between the magnetic elements  114   g  in the first section  102   a  and the magnetic elements  114   j  in the second section  102   b . The pulling force may also overcome the magnetic attraction force of magnetic elements  114   e  and the magnetic elements  114   j  (both shown in  FIG. 2 ) with the magnetic elements  114   h  and the magnetic elements  114   i  (both shown in  FIG. 2 ), respectively, and cease the magnetic coupling. 
     Once the first segment  108   a  is pulled away from the back surface  134 , the second segment  108   b  and the third segment  108   c  may disengage the back surface  134 , as denoted by the dotted lines. Moreover, the second segment  108   b  and the third segment  108   c  may disengage the back surface  134  without any additional pulling force applied to the second section  102   b . In other words, the force that causes disengagement between the first segment  108   a  and the back surface  134  is sufficient to initiate disengagement of the second segment  108   b  and the third segment  108   c  with the back surface  134 . As a result, once the magnetic elements in the first segment  108   a  are no longer magnetically coupled with magnetic elements in the first section  102   a  and the first segment  108   a  is pulled away from the back surface  134  of the first section  102   a , a disengagement of the second segment  108   b  and the third segment  108   c  from the back surface  134  is initiated in a sequential manner. That is, the second segment  108   b  disengages from the back surface  134 , followed by the third segment  108   c  disengaging from the back surface  134 . This is due in part to the magnetic coupling and offset alignment between the magnetic elements  114   k  and the magnetic elements  114   l  in the first section  102   a  with the magnetic elements  114   m  and the magnetic elements  114   n , respectively, in the second section  102   b.    
       FIG. 9  illustrates a side view of the accessory device  100 , showing the first segment  108   a  engaged with the second segment  108   b . Without any external force, the first segment  108   a  will disengage and fall away from the second segment  108   b  due to gravitational forces, as indicated by the dotted lines. Also, as shown, the first section  102   a  is folded away from the second section  102   b  such that the second section  102   b  is not engaged with the first section  102   a.    
       FIG. 10  illustrates a side view of the accessory device  100 , showing the first section  102   a  partially engaged with the second section  102   b , and the first segment  108   a  rotated to engage the second segment  108   b . As shown, the magnetic elements  114   h  in the first segment  108   a  are magnetically coupled with the magnetic elements  114   q  in the first section  102   a . The magnetic elements  114   h  and the magnetic elements  114   i  (both shown in  FIG. 2 ) in the first segment  108   a  may also magnetically couple with the magnetic elements  114   r  and the magnetic elements  114   s  (both shown in  FIG. 2 ), respectively, in the first section  102   a . As a result, the first segment  108   a  remains engaged with the second segment  108   b  due in part to the magnetic coupling between magnetic elements in the first segment  108   a  and magnetic elements in the first section  102   a . Moreover, the first segment  108   a  no longer covers a portion of the back surface  134  such that the camera assembly  184  of the electronic device  180  can protrude through the opening  106  and capture images.  FIGS. 9 and 10  illustrates that the first segment  108   a  may not remain engaged with the second segment  108   b  unless the first section  102   a  engages the second section  102   b  such that the magnetic elements in the first segment  108   a  can magnetically couple with magnetic elements in the first section  102   a.    
       FIG. 11  illustrates a side view of the accessory device  100  supporting the electronic device  180 . In this configuration, a user of the electronic device  180  can interact with the display  186  (shown as a dotted line) of the electronic device  180  when the display  186  includes touchscreen capabilities. As shown, the electronic device  180  is engaged with the first section  102   a , and magnetic elements in the electronic device  180  magnetically couple to magnetic elements in the first section  102   a . Further, the second section  102   b  can fold such that first segment  108   a , the second segment  108   b , and the third segment  108   c  form a triangular support for the electronic device  180 . As shown in the enlarged view, due in part to the layer  124   b  (also shown in  FIG. 3 ) being separate from a layer  124   c  on the third segment  108   c , a portion of the second layer  122   b  located on the first section  102   a  engages a portion of the second layer  122   b  located on the second section  102   b . Due in part to the second layer  122   b  being formed from a polyurethane material, the second layer  122   b  provides a frictional force between the portion of the second layer  122   b  located on the first section  102   a  in contact with the portion of the second layer  122   b  located on the second section  102   b . The frictional forces between the portions of the second layer  122   b  are greater than frictional forces between soft, non-abrasive layers, such as microfiber. As a result, the accessory device  100  can resist unwanted movement when, for example, a user interacts with the display  186 . Also, the third segment  108   c  provide direct support through engagement with the first section  102   a . However, in this configuration, the third segment  108   c  may not be magnetically coupled with the first section  102   a , and the weight of the electronic device  180  applies a force to the third segment  108   c  that maintains the triangular support. 
       FIG. 12  illustrates a side view of the accessory device supporting the electronic device in an alternate configuration. The user of the electronic device  180  can also interact with the display  186  of the electronic device  180  in this configuration. As shown, the first segment  108   a , the second segment  108   b , and the third segment  108   c  can fold to form an alternate triangular support for the electronic device  180 . The first section  102   a  is rigid and strong enough to support the electronic device  180  without bowing or warping, and accordingly, the first section  102   a  is not affected by the weight of the electronic device  180 . 
       FIG. 13  illustrates a plan view of the accessory device  100 , showing the camera assembly  184  and the flash module  185  of the electronic device  180  positioned in the opening  106  of the accessory device  100 . As shown, the camera assembly  184  is allowed to capture images for the electronic device  180 , and the flash module  185  may emit light to enhance the image capturing. Also, when the camera assembly  184  is in the opening  106 , the reinforcement layer  115  surrounds the camera assembly  184 . 
       FIG. 14  illustrates a side view of the accessory device  100  and the electronic device  180  shown in  FIG. 13 , showing the camera assembly  184  protruding through the opening  106  of the accessory device  100 . A partial cross sectional view of the first section  102   a  is shown to show the reinforcement layer  115 . When a force (denoted by two-sided arrow  187 ) is applied to the electronic device  180  that causes lateral movement in either direction of the two-sided arrow  187 , a corresponding lateral movement of the camera assembly  184  also occurs. However, due in part to the camera assembly  184  being positioned in the opening  106 , the camera assembly  184  can engage one or more surfaces that define the opening  106 , and limit the movement of the camera assembly  184 , thereby limiting the movement of the electronic device  180 . This allows magnetic elements (not shown  FIG. 14 ) in the first section  102   a  to remain magnetically coupled with magnetic elements (not shown  FIG. 14 ) in the electronic device  180 . Accordingly, the opening  106  provides a mechanical stop or interface when relative lateral movement of the electronic device  180  occurs. 
       FIG. 15  illustrates a side view of the electronic device  180  positioned between the first section  102   a  and the second section  102   b  of the accessory device  100 , showing the first section  102   a  and the second section  102   b  extending beyond the electronic device  180 . As shown, both the first section  102   a  and the second section  102   b  are engaged with the electronic device  180 . Further, magnetic elements in the first section  102   a  and in the second section  102   b  may magnetically couple with magnetic elements in the electronic device  180 . Moreover, the electronic device  180  may include an audio module  188 , such as a speaker module, designed to generate acoustical energy in the form of audible sound. Audio modules of this kind are known in the art to include a permanent magnet. In some instances, when the accessory device  100  is exposed to heat, a material (or materials) of the accessory device  100  may bend or warp. For example, excess heat may cause the first segment  108   a  and the second segment  108   b  to extend away and at least partially disengage the electronic device  180 , as indicated by the dotted lines. However, the accessory device  100  may include magnetic elements  114   t  in a location corresponding to the location of the audio module  188  such that magnetic elements  114   t  magnetically couple with the audio module  188 , and in particular, a permanent magnet of the audio module  188 . The magnetic attraction force between the magnetic elements  114   t  and the permanent magnet of the audio module  188  may cause the first segment  108   a  and the second segment  108   b  to remain engaged with the electronic device  180 , and overcome issues related to excess heat. As shown, the magnetic elements  114   t  are located in the first segment  108   a . However, the magnetic elements  114   t  can be located in the second segment  108   b  in order to accommodate a different location of the audio module  188  in the electronic device  180 . 
       FIG. 16  illustrates a plan view of the electronic device  180  and the accessory device shown in  FIG. 15 , showing the first section  102   a  extending beyond the electronic device  180  in multiple dimensions. The electronic device  180  is covered by the first section  102   a  and is denoted by a dotted line. The accessory device  100  may include a dimension  142   a  that allows the first section  102   a  to extend beyond a first edge  192   a  and a second edge  192   b  of the electronic device  180 . The accessory device  100  may include a dimension  142   b  that allows the first section  102   a  to extend beyond a third edge  192   c  and a fourth edge  192   d  of the electronic device  180 . Accordingly, the first section  102   a  may extend beyond the electronic device  180  along both the X- and Y-axes. The second section  102   b  (not shown in  FIG. 16 ) may include any dimensional features described for the first section  102   a.    
       FIGS. 17 and 18  show that the accessory device  100  includes a sufficient number of magnetic elements hold and retain the electronic device  180 , even when the electronic device  180  and the accessory device  100  are upright such that gravitational forces are acting on the electronic device  180  that would otherwise push the electronic device  180  along a vertical Y-axis and off of the accessory device  100 .  FIG. 17  illustrates a side view of the accessory device  100  and the electronic device  180 , showing the electronic device  180  engaged with the first section  102   a . The magnetic elements (not labeled) in the first section  102   a  couple with magnetic elements (not shown in  FIG. 17 ) of the electronic device  180  and provide a sufficient magnetic attraction force to such that gravitational forces and the weight of the electronic device  180  are countered, and the electronic device  180  remains engaged with the accessory device  100  along the first section  102   a.    
       FIG. 18  illustrates a side view of the accessory device  100  and the electronic device  180 , showing the electronic device  180  engaged with the second section  102   b . The magnetic elements (not labeled) in the second section  102   b  couple with magnetic elements (not shown in  FIG. 18 ) of the electronic device  180  and provide a sufficient magnetic attraction force to such that gravitational forces and the weight of the electronic device  180  are countered, and the electronic device  180  remains engaged with the accessory device  100  along the second section  102   b.    
       FIGS. 19 and 20  show an alternate embodiment of an accessory device  200 . It should be noted that the accessory device  200  may include any features described herein for the accessory device  100 . 
       FIG. 19  illustrates a side view of an alternate embodiment of an accessory device  200  holding the electronic device  180 , further showing an object  240  coupled with an edge of the electronic device  180 . The object  240  may include a digital stylus designed to interact with the display  186  (not shown in  FIG. 19 ) when the display  186  includes touchscreen capabilities or other input capabilities initiated by the object  240 . The accessory device  200  may include a retaining element  234  coupled with a first section  202   a  and a second section of the accessory device  200 . The retaining element  234  may include a satchel, or other type of strap, that engages and retains the object  240  such that the object  240  remains engaged with the electronic device  180  and/or the accessory device  200 . The retaining element  234  may include elastic capabilities to provide additional retaining forces. The retaining element  234  may permanently couple with at least one of the first section  202   a  or the second section  202   b . The permanent coupling may be through adhesives, sewing, melting, and/or other bonding techniques. Alternatively, the retaining element  234  may be removably coupled with at least one of the first section  202   a  and the second section  202   b . The removable coupling may include reusable adhesive materials, hook and loop features (such as Velcro), or magnetic elements. As shown, the retaining element  234  protrudes beyond surfaces of the first section  202   a  and the second section  202   b . However, in some embodiments (not shown in  FIG. 19 ), each of the first section  202   a  and the second section  202   b  include a recess that receives the retaining element  234  such that the retaining element is flush, or co-planar, with a surface of the first section  202   a  and with a surface of the second section  202   b.    
       FIG. 20  illustrates a side view of the accessory device  200  and the electronic device  180  shown in  FIG. 19 , with the object  240  removed. As shown, the retaining element  234  may contract so as to not extend in an unwanted manner, and such that it is not recognizable to a user that the retaining element  234  includes elastic properties in order to hold the object  240  (shown in  FIG. 19 ).
