     DETAILED DESCRIPTION 
     Accessories are commonly used in conjunction with consumer electronic devices, and some may be used to protect consumer electronic devices. For example, protective accessory cases may be employed to partially or fully surround a consumer electronic device such that the consumer electronic device is protected from damage. Although useful, such accessory cases can sometimes diminish the ease of use or full functionality of features on their protected electronic devices. There is thus a desire for improved electronic device protective accessory cases that are aesthetically pleasing while still allowing full functionality of features on the associated electronic devices. 
     The embodiments set forth herein provide various structures and methods for forming protective accessory cases to be used with separate portable electronic devices (also simply referred to as electronic devices). In various embodiments, an accessory case for an electronic device can include at least a structural shell, a camera opening, and a button cover. The structural shell can include a size and shape to receive and contain the electronic device, and also protect the electronic device. The button cover is positioned to align with a button of the electronic device when the electronic device is contained within the structural shell. The accessory case may further include an outer layer and an internal layer that cover the structural shell. The outer and internal layers may be formed from the same material. Alternatively, the internal layer may include a microfiber lining. The camera opening may define a through hole formed in the structural shell and the aforementioned layers in a location that aligns with a camera of the electronic device when the electronic device is contained within the structural shell. The camera opening can include a chamfered or angled edge that reduces camera flash effects (associated with reflected light from the camera flash) to the camera during use of the camera. As such, no additional trim may be needed around the camera opening. The button cover can include an outer button cover component that is separate from and coupled to the outer layer. 
     The various embodiments set forth herein provide several improvements in protective accessory cases for portable electronic devices, particularly with respect to camera openings and button covers on such improved accessory cases. In some embodiments, the outer layer of the accessory case can include silicone, plastic, or a similar material, and the outer button cover component can also include a silicone, plastic, or a similar material. In other embodiments, the outer layer can include leather and the outer button cover component can include anodized aluminum. In some embodiments, the outer button cover component can also include a different color than that of the outer layer to increase aesthetic effects of the accessory case. 
     The various embodiments set forth herein provide methods for forming an accessory case for an electronic device. For example, in some embodiments, an outer layer is adhered to an internal layer to form a structural shell. Also, in some embodiments, an opening, or through hole, is created through the structural shell, the outer layer, and the internal layer. Also, an outer button cover component can be placed over the opening at an outer surface. Further, a backing plate can be placed over the opening at an inner surface. Further, a fastener can be inserted into an opening through the backing place and a cavity in the outer button cover component. Also, the fastener can be compressed against the backing plate and into the cavity to form an interference fit between the various components. 
     The foregoing approaches provide various structures and methods for the disclosed protective accessory cases for portable electronic devices. A more detailed discussion of these structures, methods, and features thereof is set forth below and described in conjunction with  FIGS. 1-22 , which illustrate detailed diagrams of devices and components that can be used to implement these structures, methods, and features. 
       FIG. 1A  illustrates a top plan view of an exemplary portable electronic device, or simply an electronic device, according to various embodiments of the present disclosure. The electronic device  100  can take the form of a smart phone, for example, although it will be readily appreciated that such a device might also be a media playback device, a personal digital assistant, a laptop computer, or any other suitable portable electronic device. The electronic device  100  can include an outer housing  102 , or enclosure, which can be adapted to hold a processor and other electronic components inside, and can also provide space for a display  104  (which may include a touchscreen), and one or more speakers, microphones, ports, and jacks, among other possible device components. In particular, the electronic device  100  can include a camera (not shown), and one or more side buttons, such as a first button  106  and a second button  108 . However, the first button  106  and/or the second button  108  may be replaced or substituted with a switch. The electronic device  100  can also be suitable for use with a protective accessory case, which is described in greater detail below. 
       FIG. 1B  illustrates a rear plan view of the electronic device  100  shown in  FIG. 1A . As shown, the electronic device  100  may include a camera  120  designed to capture images, in the form of still images and/or video. In order to enhance the appearance of the images, the electronic device  100  may further include a camera flash  122  that provides a light source for illumination during use of the camera  120 . Both the camera  120  and the camera flash  122  may protrude, or at least be made visible, by an opening in the outer housing  102 . 
       FIGS. 2A-2B  illustrate an exemplary protective accessory case (or simply accessory case) suitable for use with an electronic device, such as the electronic device  100  (shown in  FIGS. 1A and 1B ). The accessory case  200  can include a protective case that is used to contain and protect an associated and separate portable electronic device.  FIG. 2A  illustrates a top plan view of the accessory case  200 . The accessory case  200  may include a structural shell covered by one or more layers. The structural shell may include a hard or durable material, such as plastic, hardened silicone, leather, or a composite material. Also, the structural shell may be referred to as an internal layer throughout this detailed description due to its positioning between the outer and internal layers. This will be further discussed below. The accessory case  200  may include a planar back region  212  and sidewalls  214  extending from the planar back region  212 . The accessory case  200  may further include camera opening  220 , or through hole, in the planar back region  212 . The camera opening  220  is in a location corresponding to the camera  120  and the camera flash  122  (both shown in  FIG. 1B ). In this regard, the camera opening  220  can allow access to the camera  120  and the camera flash  122 , and does not cover these features. Also, the accessory case  200  may include several button covers, such as a first button cover  230  and a second button cover  232 , that are positioned on one of the sidewalls  214 , and in particular, in a location corresponding to the first button  106  and the second button  108  (both shown in  FIG. 1A ), respectively. In this manner, the button covers are aligned with the buttons of the electronic device. It should be noted that the number of button covers may match the number of buttons of an electronic device, and may be in a location or locations corresponding to the buttons of an electronic device. 
       FIG. 2B  illustrates a side view of the accessory case  200  shown in  FIG. 2A . As shown, the planar back region  212  and the sidewalls  214  may combine to form an internal volume  240  having a size and shape to receive an electronic device, such as the electronic device  100  (shown in  FIG. 1A ). Accordingly, the internal volume  240  may represent a void or space in the accessory case  200 . 
     As shown in  FIGS. 2A-2B , Cartesian axes X, Y, and Z form a right-handed coordinate frame for illustration purposes only. Accordingly, the accessory case  200  may include a substantially planar profile in the XY plane (as shown in  FIG. 2A ), with a thickness along the Z axis (as shown in  FIG. 2B ). These features can correlate substantially to that of an electronic device for which the accessory case  200  can be used. One of ordinary skill will recognize that the terms ‘besides,’ ‘above,’ and ‘bottom’ are not limiting of embodiments disclosed herein, and only used in context to indicate a relative positioning of elements. Further, in order to depress the aforementioned of buttons of an electronic device when the electronic device is positioned in the accessory case  200 , the first button cover  230  and the second button cover  232  may be actuated along an axis that is aligned substantially along the X-axis (as shown in  FIG. 2A ). Alternatively, the first button cover  230  and the second button cover  232  may be located elsewhere, in accordance with alternate locations of the buttons, and may include an actuation axis in another direction. 
     In many arrangements, a camera opening on an accessory case can provide access to a camera and a camera flash on an associated portable electronic device for which the accessory case is being used. Due to the relatively small nature of many portable electronic devices, the camera flash is often placed in close proximity to the camera such that light from the camera flash often corrupts or interferes with an image(s) captured by the camera, resulting in pictures of lesser quality. However, accessory cases and/or associated portable electronic devices described herein may include features that account for such undesirable camera flash effects. 
       FIG. 3  illustrates a cross-sectional view of an accessory case  400  with an electronic device  350  positioned in the accessory case  400 , according to various embodiments of the present disclosure. For purposes of simplicity and illustration, various portions of the electronic device  350  and the accessory case  400  are not shown. As shown, the electronic device  350  may include an enclosure  352  and a camera  356  aligned with an opening of the enclosure  352 . Also, the camera  356  may include a protective layer  358 , which may include glass or plastic, covering a lens (not shown) of the camera  356 . 
     The accessory case  400  may include an internal volume having a size and shape in accordance with the electronic device  350 . In other words, the accessory case  400  is sized and shaped to receive the electronic device  350 . Also, the accessory case  400  may include a camera opening  420  representing a through hole in layers of the accessory case  400 . Also, the camera opening  420  is in a location corresponding to the camera  356  and a light source (not shown) that provides a camera flash, such that the camera  356  and the light source are accessible to a user through the accessory case  400 . 
     The accessory case  400  may further include an accessory trim  422  that surrounds an outer circumference of the camera opening  420 . The accessory trim  422  enhance an appearance of the accessory case  400  at the camera opening  420 . This accessory trim  422  may be separate from or integrally formed with the rest of accessory case  400 . Also, the accessory trim  422  can include black or darkened color, and accordingly, the accessory case  400  may include relatively dark appearance surrounding the circumference of camera opening  420 . This relatively dark region may minimize the effect of wayward camera flash on the camera  356  itself. In addition, one or more other components at or near the accessory trim  422  can be of a black or darkened color as well. Such darkened regions can function to absorb some of the reflected light from the camera flash, such that the absorbed light does not enter the camera  356  during an image capture event. 
     In addition to absorbing camera flash, the accessory trim  422  can also help to protect the camera  356  and the protective layer  358  in the event of drops or other jarring event to the electronic device  350  and accessory case  400 . As such, the accessory trim  422  may include a plastic, silicone, or other suitably firm material that is adapted to provide shock absorption. In addition, the protective layer  358  can be recessed some distance from a plane defined by the outer surface of the accessory trim  422  of the accessory case  400 , as exemplified in  FIG. 3 . This plane can also be the same plane that defines the outer surface of the accessory case  400  such that the accessory trim  422  is co-planar, or flush, with respect to the outer surface (in this case, the outer layer  424  depicted in the enlarged view). Accordingly, drops or other sudden contacts are more likely to impact the accessory trim  422  and/or the accessory case  400 , rather than impact the protective layer  358  and the camera  356 . In various arrangements, a recessed distance  430  between the outer surface of the accessory case  400  and the protective layer  358  can be approximately 0.5 to 1 millimeters (“mm”), although other recessed distances are also possible as may be desired. 
     The enlarged view in  FIG. 3  depicts different layers of the accessory case  400  as the accessory case  400  abuts the enclosure  352  of the electronic device  350 . In addition to the accessory trim  422  around the camera opening  420 , the accessory case  400  can also include an outer layer  424 , an internal layer  426 , and a microfiber lining  428  along an internal surface. In this regard, the outer layer  424 , the internal layer  426 , and the microfiber lining  428  can collectively form the accessory case  400 . The outer layer  424  may include a material that forms an aesthetically pleasing exterior for the accessory case  400 , such as silicone, leather, or various types of softer plastics. The internal layer  426 , which may also be referred to as a “frame,” a structural shell, or other suitable structural term, may include a more rigid material that is suited to provide firm structure and dampen or dissipate shocks, such as a polycarbonate or hard plastic. The microfiber lining  428  can be a thin and smooth material that provides reduced friction or abrasions when placed in contact with the enclosure  352 . 
     Where the accessory trim  422  can be a separate part that is formed within the camera opening  420 , the various layers of the accessory case  400  may be stepped with respect to the location of the accessory trim  422 . For example, the accessory trim  422  may be placed around the ends of the outer layer  424  and the internal layer  426 , such that the ends of these layers are not visible. In some instances, the accessory trim  422  may include a trim end  432  that extends into the camera opening  420  farther than an end  434  of the microfiber lining  428 , creating a stepped arrangement and appearance between the accessory trim  422  and the microfiber lining  428 . 
       FIG. 4  illustrates a cross-sectional view of an exemplary alternative camera opening region on a protective accessory case, according to various embodiments of the present disclosure. As shown, an electronic device  450  is positioned in an accessory case  500 . The electronic device  450  may include a housing  452  having an opening for a camera  456 . The camera  456  may include a protective layer  458  that covers a lens (not shown) of the camera  456 . The camera  456  can be made accessible through a camera opening  520  of the accessory case  500 . The camera opening  520  can take the form of a through hole formed in the accessory case  500 , such that the camera  456  is accessible therethrough. Although, the accessory case  500  does not include an accessory trim, the camera opening  520  can still include many features similar to that of camera opening  420  (shown in  FIG. 3 ). 
     For example, rather than have any accessory trim, the accessory case  500  may include an angled region  522  around the camera opening  520 . Specifically, the angled region  522  can provide a gradually sloped angle or chamfer that surrounds the camera opening  520 , as shown in  FIG. 4 . The angled region  522  can be formed by chamfering one or more layers of the accessory case  500 , such as an outer layer and an internal layer (discussed below). This angled region  522  can function to reflect and/or refract some of the light (from a camera flash) away from the camera opening  520 , such that the reflected or refracted light does not enter the camera  456  during an image capture event of the camera  456 . 
     In addition to reducing camera flash effects on the camera  456 , the angled region  522  can also help to protect the camera  456  and the protective layer  458  in the event of drops or other jarring events to the electronic device  450 . In general, the protective layer  458  can be recessed some distance from a plane defining the outermost surface of the accessory case  500  near the camera opening  520 . Accordingly, drops or other sudden contacts are more likely to impact the accessory case  500 , rather than impact the protective layer  458  and the camera  456 . In various arrangements, a recessed distance  540  between the outer surface of the accessory case  500  and the protective layer  458  can be approximately 0.2 to 1 mm, although other recessed distances are also possible as may be desired. 
     The enlarged view in  FIG. 4  depicts different layers of the accessory case  500  as the accessory case  500  abuts the housing  452  of the electronic device  450 . Similar to the foregoing embodiment, the accessory case  500  can include an outer layer  524 , an internal layer  526 , and a microfiber lining  528 , with the outer layer  524  and the microfiber lining  528  positioned on an exterior surface and an interior surface, respectively, of the internal layer  526 . The outer layer  524 , internal layer  526 , and microfiber lining  528  can collectively form the accessory case  500  in some embodiments. The outer layer  524  may include a material such as silicone, leather, or various types of softer plastics. The internal layer  526  may include a more rigid material that is suited to a structural shell that dampens or dissipates shocks. The microfiber lining  528  can be a smooth material that provides reduced friction or abrasions when placed in contact with the associated portable electronic device. 
     The angled region  522  can represent a chamfer in one or more of the outer layer  524 , the internal layer  526 , and the microfiber lining  528 . However, shown in the enlarged view, only the edge of the internal layer  526  is chamfered. This can result in a constant or near constant thickness for each of the outer layer  524  and the microfiber lining  528 , and can also result in an overall chamfer around the circumference of the camera opening  520 . The angled region  522  can result in a gradual tapering of the accessory case  500  around the camera opening  520  of the accessory case  500 , such that light from the camera flash is reflected, refracted, and/or otherwise directed away from the camera opening  520 . The angle of the angled region  522  can vary as may be suitable for the dimensions of the camera  456 , the electronic device  450 , the camera opening  520 , and/or the accessory case  500 . In various embodiments, the angled region  522  may include a chamfered edge that rises at an angle approximately between 5 and 90 degrees with respect to a plane  542  (represented by a horizontal dotted line) that is parallel with respect to the protective layer  458 . In some embodiments, the angle can be between approximately 10 and 30 degrees. 
     Unlike the foregoing embodiments, no darkened region is used to minimize the amount of flash that interferes with the camera. This can result in an improved appearance having a continuous color and texture at the boundary of the camera opening  520 . Furthermore, unlike the foregoing embodiment, the various layers of the accessory case  500  are not necessarily stepped with respect to the location of the camera opening  520 . As shown, the outer layer  524  may include an outer layer end  532  that extends into the camera opening  520  the same distance as a microfiber end  534  of microfiber lining  528 , creating an even arrangement and appearance between the outer layer  524  and the microfiber lining  528 . This even arrangement can also create a smoother and more aesthetically pleasing appearance for the accessory case  500 . The even arrangement and appearance at the outer layer end  532  and the microfiber end  534  can be achieved by adhering these materials together and then cutting them to form the camera opening  520 . 
       FIG. 5  illustrates an enlarged cross-sectional view of another exemplary alternative camera opening region on a protective accessory case, according to various embodiments of the present disclosure. As shown, an electronic device  550  is positioned in an accessory case  600 . With an electronic device  550  positioned in the accessory case  600 , at least one of the layers of the accessory case  600  may abut a housing  552  of the electronic device  550 . The accessory case  600  may further include a camera opening  620 , defining a through hole in the layers of the accessory case  600 , exposing a protective layer  558  and a camera  556 , both of which are part of the electronic device  550 . 
     The accessory case  600  may include an outer layer  624 , an internal layer  626 , and a microfiber lining  628 . The outer layer  624 , the internal layer  626 , and the microfiber lining  628  can collectively form the accessory case  600 . The outer layer  624  may include a relatively softer material that is still aesthetically pleasing for regular use, such as leather, cloth, or various types of softer plastics. In addition to being on the outside of the accessory case  600 , the material for the outer layer  624  may also wrap around the internal layer  626  or otherwise form a portion of a surface of the accessory case  600 , as shown. Accordingly, the outer layer  624  may include a single piece of material that also defines an inner layer of the accessory case  600 . Also, the outer layer  624  and the microfiber lining  628  can combine to form the inside surface of the accessory case  600 , and in some cases, the full inside surface of the accessory case  600 . Also, the internal layer  626  may include a rigid material that is suited to provide firm structure and dampen or dissipate shocks, and the microfiber lining  628  can be a smooth material that provides reduced friction or abrasions when placed in contact with the electronic device  550 . 
     The accessory case  600  may include an angled region  622  that represents an edge that is rounded or chamfered near the camera opening  620 . The angled region  622  may be created by modifying one or more of the outer layer  624 , the internal layer  626 , and the microfiber lining  628 . Accordingly, the outer surface of the accessory case  600  can be angled or chamfered toward an edge at the camera opening  620 . As shown in  FIG. 5 , only the end of the internal layer  626  is angled or chamfered. Similar to the foregoing embodiment, the angled region  622  can result in a tapering of the accessory case  600  around the camera opening  620 , such that light from the camera flash is more readily reflected, refracted, and/or otherwise directed away from the camera opening  620 . The angle of the angled region  622  can vary as may be suitable for the dimensions of the camera  556 , the electronic device  550 , the camera opening  620 , and/or the accessory case  600 . The angled region  622  can rise at an angle that is approximately between 5 and 90 degrees with respect to a plane  642  (represented by a horizontal dotted line) that is parallel to the protective layer  558  of the camera  556 . However, in embodiments, the angled region  622  is formed at an angle between about 10 and 30 degrees. 
     In this embodiment, no darkened region is used in conjunction with angled region  622  to minimize the amount of reflected light from the flash that interferes with the camera  556 . Also, with no structural element(s) representing a darkened region of the accessory case  600  can result in an improved appearance having a continuous color and texture at the boundary of the camera opening  620 . Further, the various layers of the accessory case  600  are not stepped with respect to the location of the camera opening  620 , such that the outer layer  624  may include an end  632  that extends to the camera opening  620  the same distance as an end  634  of microfiber lining  628 , creating an even arrangement and appearance between the ends of the outer layer  624  and the microfiber lining  628 . This even arrangement can also create a smoother and more aesthetically pleasing appearance for the accessory case  600 . Again, the even arrangement and appearance at the end  632  of the outer layer  624  and the end  634  of the microfiber lining  628  can be achieved by adhering these materials together and then cutting them to form the camera opening  620 . 
     In addition to reducing camera flash effects to the camera  556 , the angled region  622  can also help to protect the camera  556  and the protective layer  558  in the event of drops or other jarring events to the electronic device  550  and accessory case  600 . In various arrangements, a recessed distance  640  between the protective layer  558  and a plane  642  (parallel with respect to an outermost surface of the accessory case  600 ) can be approximately 0.2 to 1 mm, although other recessed distances are also possible as may be desired. Accordingly, drops or other sudden contacts are more likely to impact directly the accessory case  600 , rather than impact directly the protective layer  558  and/or the camera  556 . 
       FIG. 6A  illustrates an exploded view of various components for an alternative camera opening according to various embodiments of the present disclosure. An accessory trim  650  may include one or more features used in an accessory case and positioned around an opening in the accessory case, with the opening in a location corresponding to a camera and a camera flash of an electronic device. The accessory trim  650  may include a first ring  652 . In some embodiments, the first ring  652  is formed from a metal, such as aluminum. Also, the first ring  652  can be anodized to enhance the appearance and/or rigidity of the first ring  652 . Also, the accessory trim  650  may further include a second ring  654  designed to mate, or attach, with the first ring  652 . In some embodiments, the second ring  654  includes a polymeric material, such as plastic. Further, in some embodiments, the second ring  654  includes a moldable polymer. In this regard, the second ring  654  may couple with the first ring  652  by a molding operation, such as insert molding, whereby the first ring  652  is placed in a mold cavity (not shown) and the moldable polymer is injected into the mold cavity to form the second ring  654 . The combination of the first ring  652  and the second ring  654  can form an outer circumference for a camera opening that can be formed on an accessory case for containing and protecting an associated portable electronic device having a camera. 
       FIG. 6B  illustrates a cross-sectional view of the first ring  652  and the second ring  654  shown in  FIG. 6A . As shown, the first ring  652  may include a protrusion  662  and the second ring  654  may include a recess  664 . The first ring  652  may interlock with the second ring  654  when the recess  664  receives the protrusion  662 . It should be noted that the protrusion  662  and the recess  664  may extend around the first ring  652  and the second ring  654 , respectively, in selected portions or may include a continuous feature around a circumference of the respective rings. 
       FIG. 7A  illustrates a front perspective view of an accessory case having a camera opening according to various embodiments of the present disclosure. The accessory trim  750  may be substantially similar to the accessory trim  650  (shown in  FIG. 6A ), and accordingly, may include similar parts and materials. As shown, the accessory trim  750  can be formed around a camera opening  720  of the accessory case  700 , with the camera opening  720  providing access to a camera and camera flash on a portable electronic device (not shown) contained within the accessory case  700 . A first ring  752  can surround the full circumference of the camera opening  720  and can be the only portion of the accessory trim  750  that is visible from an exterior of the camera opening  720 . In other words, the first ring  752  may cover an additional ring(s). 
       FIG. 7B  illustrates a cross-sectional view of the accessory case  700  shown in  FIG. 7A . The accessory case  700  may include an outer layer  724 , which may include leather. The accessory case  700  may further include an internal layer  726  covered by the outer layer  724 . The internal layer  726  may include polycarbonate or hard plastic, as in previous embodiments. The accessory case  700  may further include a microfiber lining  728 . 
     The accessory case  700  may further include a first ring  752  located atop a second ring  754 , with the combined rings inserted around the camera opening  720 . The first ring  752  and the second ring  754  may include any material(s) previously described for a first ring and a second ring, respectively. Also, the outer layer  724  may wrap, or at least partially wrap, around the internal layer  726 . Further, the outer layer  724  may combine with the atop the internal layer  726  and around the circumference of the camera opening  720 , while the microfiber lining  728  can be located at the bottom of the internal layer  726  to facilitate a uniform appearance. Also, in this configuration, the second ring  754  may be covered from view by the first ring  752 , the outer layer  724 , and the microfiber lining  728 . 
     While various improvements in camera openings have been illustrated and discussed, the disclosed protective accessory cases also provide various improvements in button covers. While the following exemplary accessory cases show and describe various embodiments of a button cover for the accessory case, it should be noted that a single accessory case may include both a camera opening with various embodiments of an accessory trim described herein, as well as various embodiments of a button cover described herein. 
       FIG. 8  illustrates a cross-sectional view of an exemplary button cover region on a protective accessory case, according to various embodiments of the present disclosure. As shown, an electronic device  850  includes a button  852 , along with an accessory case  900  designed to cover the electronic device  850  and the button  852 . For purposes of reference and illustration, only a portion of the electronic device  850  and a portion of the accessory case  900  are shown. 
     The accessory case  900  can include an outer layer  924 , an internal layer  926 , and a microfiber lining  928 . As shown, the internal layer  926  may include an opening therethrough to accommodate the button cover  910 . Conversely, the outer layer  924  and the microfiber lining  928  can continue through the button cover  910 , albeit with modifications to accommodate the button cover  910 . Accordingly, the region of the button cover  910  can include some layers of the accessory case  900 , as well as various other button cover components. In various embodiments, the outer layer  924  may include silicone or a suitable thermoplastic material, while the internal layer  926  may include a more rigid material. Also, in some cases, the button cover  910  includes no additional parts that are separate from the layers of the accessory case  900 . 
     The button cover  910  can include an outer button cover component  912 , which represents the primary component for a user to access in order to facilitate actuation of the button  852  of the electronic device  850 . That is, the outer button cover component  912  can be positioned over the button  852  and actuated in order to accept a user input and facilitate transfer of the user input to actuate the button  852 . As such, the outer button cover component  912  is designed to move toward the button  852 , and through the opening in the internal layer  926 . 
     Also, the outer button cover component  912  can be integrally formed with the outer layer  924 . To facilitate the physical movement of the outer button cover component  912 , the outer layer  924  may include a web region  934  surrounding the button cover  910 . The web region  934  can represent a relatively thin portion of the outer layer  924  such that the button cover  910  can readily flex and move when a force is applied to the button cover  910  to actuate the button  852 . In addition, the microfiber lining  928  may include an indented flexure region  938 , which can also be configured to flex and move with the outer button cover component  912 . As shown, various gaps between the outer layer  924 , the internal layer  926 , and the microfiber lining  928  may also exist to facilitate movement and flexure of components, such as the outer button cover component  912 . Also, the outer button cover component  912  can be located at and supported by the outer layer  924  in various embodiments. 
       FIG. 9  illustrates a side cross-sectional view a second exemplary button cover region on a protective accessory case, according to various embodiments of the present disclosure. As shown, an electronic device  950  may include a button  952 , along with an accessory case  1000  designed to cover the electronic device  950  and the button  952 . Also, the accessory case  1000  may include a button cover  1010  positioned in a location to cover the button  952  when the electronic device  950  is positioned in the accessory case  1000 . For purposes of reference and illustration, only a portion of the electronic device  950  and a portion of the accessory case  1000  are shown. 
     As in the foregoing example, the region associated with the button cover  1010  can include portions of the accessory case  1000 , as well as various other button cover components. The accessory case  1000  can include an outer layer  1024 , an internal layer  1026 , and a microfiber lining  1028 . The internal layer  1026  may include an opening therethrough to accommodate the button cover  1010 . However, unlike the foregoing example, the outer layer  1024  in  FIG. 9  may include an opening therethrough to accommodate the button cover  1010 . In various embodiments, the outer layer  1024  can similarly be formed from silicone or a suitable thermoplastic material, while the internal layer  1026  may include a more rigid material. 
     The button cover  1010  may include additional parts that are separate from the layers of the accessory case  1000 . For example, the button cover  1010  can include an outer button cover component  1012 , which can be located along and supported by the outer layer  1024 . Also, the outer button cover component  1012  can be the primary component to facilitate actuation of the button  952 . As such, the outer button cover component  1012  can be configured to accept a user input and facilitate transfer of the user input to actuate the button  952 . Also, the outer button cover component  1012  can be configured to move through an opening in the internal layer  1026 . The outer layer  1024  may include a web region  1034  surrounding the button cover  1010 . The web region  1034  can represent a relatively thin portion of the outer layer  1024  such that the button cover  1010  can readily flex and move when a force is applied to the button cover  1010  to actuate the button  952 . Also, the microfiber lining  1028  may include an indented flexure region  1038  that flexes and moves with the button cover  1010 , and various gaps between the outer layer  1024 , the internal layer  1026 , and the microfiber lining  1028  may also exist to facilitate the movement and flexure of components, including the outer button cover component  1012 . 
     As shown in  FIG. 9 , the outer button cover component  1012  can be a separate part from the outer layer  1024 , and can be glued, press fit, and/or otherwise affixed within a recess in the outer layer  1024 , with the recess being in a location corresponding to the button  952  when the electronic device  950  is positioned in the accessory case  1000 . This can result in the outer layer  1024  having a flange region  1036  that extends inward from the web region  1034  in the outer layer  1024 . Also, the flange region  1036  may be relatively thin as compared to the web region  1034 . Also, due in part to the separable configuration, the outer button cover component  1012  can include a different color and/or contrast, as compared to the color and/or contrast of the outer layer  1024 , and can also have a different feel or texture than the outer layer  1024 . Such differences can be used to enhance the overall aesthetic appearance of the accessory case  1000 . As shown, the outer button cover component  1012  can define an outer shell that covers an inner button cover component  1014 . The inner button cover component  1014  may include a flange  1016  that functions to hold the outer button cover component  1012  in place as it wraps around the flange  1016 . Also, the button cover  1010  may include a button cover base  1018  located between the outer layer  1024  and the microfiber lining  1028 . As shown, the button cover base  1018  is sandwiched between the inner button cover component  1014  and the microfiber lining  1028  where the opening exists in the internal layer  1026 . The button cover base  1018  may include a recess that accepts a protrusion  1022  of the inner button cover component  1014  such that some of the separate components, such as the inner button cover component  1014 , do not shift and are held in place against each other. 
     In various embodiments, the outer button cover component  1012  may include a silicone or thermoplastic material that is the same or similar to the material of the outer layer  1024 . Accordingly, the outer button cover component  1012  and the outer layer  1024  can be similar in appearance and feel, but may be distinguish as noted above, such as by having different colors. However, in some instances, the outer button cover component  1012  includes a metal, such as aluminum, including anodized aluminum. The inner button cover component  1014  may include a polycarbonate material and the button cover base  1018  can also be formed from the same or a similar polycarbonate material. When making the button cover  1010 , the inner button cover component  1014  can be glued or otherwise affixed to the button cover base  1018 . The outer button cover component  1012  can be formed atop the inner button cover component  1014 . For example, the outer button cover component  1012  can be formed from silicone and molded around the inner button cover component  1014 . Due in part to the outer button cover component  1012  being a physically separate part from the outer layer  1024 , these parts can readily be created in different colors or appearances. In addition, a more definitive tactile feedback may also be experienced when the button cover  1010  is depressed to actuate the button  952 . 
       FIG. 10  illustrates a cross-sectional view of a third exemplary button cover region on a protective accessory case according to various embodiments of the present disclosure. As shown, an electronic device  1050  may include a button  1052 , along with an accessory case  1100  designed to cover the electronic device  1050  and the button  1052 . Also, the accessory case  1100  may include a button cover  1110  positioned in a location to cover the button  1052  when the electronic device  1050  is positioned in the accessory case  1100 . For purposes of reference and illustration, only a portion of the electronic device  1050  and a portion of the accessory case  1100  are shown. 
     The region for button cover  1110  can include portions of the accessory case  1100 , as well as various other button cover components. The accessory case  1100  can again include an outer layer  1124 , an internal layer  1126 , and a microfiber lining  1128 . The internal layer  1126  may include an opening to accommodate the button cover  1110 , while the microfiber lining  1128  may include a flexure region  1138  that flexes and moves with the button cover  1110 . The outer layer  1124  continues through the button cover  1110  and as such does not include an opening, but does have features to accommodate the button cover  1110 . In various embodiments, the outer layer  1124  can similarly be formed from silicone or a suitable thermoplastic material, while the internal layer  1126  may include a more rigid material. 
     The button cover  1110  can include an outer button cover component  1112 , which can be located at and supported by the outer layer  1124 , and can be the primary component to facilitate actuation of the button  1052  of the electronic device  1050 . As such, the outer button cover component  1112  is designed to accept a user input and facilitate transfer of the user input to actuate the button  1052 . The outer button cover component  1112  is designed to move with respect to the button  1152  by passing through an opening in the internal layer  1126 . The outer layer  1124  may include a web region  1134  surrounding the button cover  1010 . The web region  1134  can represent a relatively thin portion of the outer layer  1124  such that the button cover  1110  can readily flex and move when a force is applied to the button cover  1110  to actuate the button  1052 . 
     As shown in  FIG. 10 , the outer button cover component  1112  can be a separate part from the outer layer  1124 , and can be glued, press fit, and/or otherwise affixed within a recess  1136  in the outer layer  1124 . Unlike the foregoing embodiment, there is no opening, or through hole, through the outer layer  1124  at the recess  1136 , and there are no additional polycarbonate or other button cover components. Rather, a flange  1114  extends around the circumference of the outer button cover component  1112  can be used to provide extra features and a stepped surface geometry in order for the outer button cover component  1112  to be more firmly press fit, glued, or otherwise affixed within the outer layer  1124  at the recess  1136 . In this regard, the continuous nature of the outer layer  1124  can be shaped to accommodate the exact shape of the outer button cover component  1112  as shown. 
     As in the previous embodiment, the outer button cover component  1112  can include a different color and/or contrast, and can also have a somewhat different feel or texture than the outer layer  1124 , since the outer button cover component  1112  is physically separate from the outer layer  1124 , and can be made separately. Such differences can again be used to enhance the overall aesthetic appearance of the accessory case  1100 . In various embodiments, the outer button cover component  1112  may include a silicone or thermoplastic material that is the same or similar to the material of the outer layer  1124 , such that these parts can be similar yet distinguishable, such as by having different colors or contrasts. A silicone-to-silicone adhesive may be used to adhere outer button cover component  1112  to the outer layer  1124 , as detailed below. 
       FIG. 11  illustrates a cross-sectional view of an alternative arrangement for the third exemplary button cover region of  FIG. 10  according to various embodiments of the present disclosure. As shown, an electronic device  1150  may include a button  1152 , along with an accessory case  1200  designed to cover the electronic device  1150  and the button  1152 . Also, the accessory case  1200  may include a button cover  1210  positioned in a location to cover the button  1152  when the electronic device  1150  is positioned in the accessory case  1200 . Also, the accessory case  1200  may include an outer layer  1224 , an internal layer  1226 , and a microfiber lining  1228 . For purposes of reference and illustration, only a portion of the electronic device  1150  and a portion of the accessory case  1200  are shown. 
     The accessory case  1200  can be substantially similar to the accessory case  1100  (shown in  FIG. 10 ), with some alternative features. For example, as shown in the enlarged view, the button cover  1210  may include an outer button cover component  1212  that includes a rear portion  1244  extending through an opening of the outer layer  1224  and abutting the microfiber lining  1228 . The outer button cover component  1212  may further include an interlocking flange  1246  that extends into a gap  1232  in the outer layer  1224 . The interlocking flange  1246  can snap into place within the gap  1232  during assembly, thereby providing an additional mechanical locking function to prevent failure or removal of the outer button cover component  1212  from the outer layer  1224 . Some of the gap  1232  may remain unfilled, so as to provide flow or runoff for adhesive that is used to adhere the outer button cover component  1212  to the outer layer  1224  and/or to the microfiber lining  1228 . As an alternative embodiment, the outer button cover component  1212  and the outer layer  1224  may be co-molded in a different process of formation. 
       FIGS. 12A-12D  illustrate a block diagram format of a manufacturing process used to form the third exemplary button cover region shown in  FIG. 11 , according to various embodiments of the present disclosure. As noted above, a silicone-based adhesive can be used to adhere a silicone outer button cover component to a separate silicone outer layer, such as within a recess of the silicone outer layer. This silicone-based adhesive can be, for example, a two-part glue comprising a catalyst and a polymer that are mixed together, resulting in a time-sensitive ability to apply the adhesive to adhere the silicone parts together. The manufacturing process  1260  can include a track  1270  that shuttles an accessory case  1250  atop an expandable buck  1272  for processing from station to station. In some embodiments, the accessory case  1250  may be processed as a whole, while in other embodiments only a portion or layer of the accessory case  1250  may be processed. For example, the manufacturing process  1260  might be performed only to an outer layer before that layer is then adhered to any other portions of the accessory case  1250 . 
       FIG. 12A  illustrates a first station  1262  in the manufacturing process  1260  that may include activating a region of an outer surface of the accessory case  1250  or a suitable part thereof. This can be done by way of a cleaning, a plasma discharge, a laser sanding, or any other activation method that may be suitable for the material of the outer surface. The activated region may include the bottom and walls of a recess in an outer layer of the accessory case  1250 , such as in the case of the recess  1136  in outer layer  1124  in the embodiment shown and described in  FIG. 10 .  FIG. 12B  illustrates a second station  1264  in the manufacturing process  1260  that may include dispensing glue or another suitable adhesive to the activated region of the outer surface of the accessory case  1250 .  FIG. 12C  illustrates a third station  1266  in the manufacturing process  1260  that may include loading a suitable outer button cover component to the activated region of the accessory case  1250  that includes the adhesive. This loading can involve the use of a vacuum hold, and can involve inserting the outer button cover component  1112  into recess the  1136  (shown in  FIG. 10 ).  FIG. 12D  illustrates a fourth station  1268  in the manufacturing process  1260  that may include applying heat and pressure to the outer button cover component and activated region of the accessory case  1250 , which can activate the glue or adhesive in order to affix the outer button cover component to the outer surface, such as at the recess. It should be noted that the track  1270  depicted in  FIGS. 12A-12D  may include a continuous track that includes each of the aforementioned stations. 
     While the foregoing exemplary embodiments can be applied to accessory cases and button covers that are all formed from silicone or a similarly molded material, other accessory case embodiments may involve the use of other materials. In various further embodiments detailed below, the outer layer of the accessory case may include a leather or cloth material, and the button covers may include metal, such as aluminum or steel. 
       FIG. 13  illustrates a cross-sectional view of a fourth exemplary button cover region on a protective accessory case, according to various embodiments of the present disclosure. Similar to the forgoing exemplary embodiments, the accessory case  1300  shown in  FIG. 13  may include a button cover  1310  as well as various components designed to contain an electronic device  1350  having a button  1352 . Again, only a portion of the electronic device  1350  and a portion of the accessory case  1300  are shown for illustrative and reference purposes. As in the foregoing examples, the region for the button cover  1310  can include portions of the accessory case  1300 , as well as various other button cover components. The accessory case  1300  can include at least an outer layer  1324  and an internal layer  1326 , the latter of which can be formed from a relatively rigid material and may include an opening therethrough to accommodate the button cover  1310 . Also, similar to the foregoing embodiments, the button cover  1310  can include an outer button cover component  1312  located at, and supported by, the outer layer  1324 , and can be the primary component to facilitate actuation of the button  1352 . Accordingly, the outer button cover component  1312  is designed to accept a user input and facilitate transfer of the user input to actuate the button  1352  of the electronic device  1350 . Also, the outer button cover component  1312  is designed to move with respect to the button  1352 , such as through an opening in the internal layer  1326 . Also, the outer layer  1324  may include a web region  1334  surrounding the outer button cover component  1312 . The web region  1334  can represent a relatively thin portion of the outer layer  1324  such that the button cover  1310  can readily flex and move when a force is applied to the button cover  1310  to actuate the button  1352 . 
     In some embodiments, the outer layer  1324  may include leather, cloth, or another suitable soft material, while the outer button cover component  1312  can be a separate part that is formed from a metal material, such as aluminum or anodized aluminum. The anodized aluminum or other metal may be dyed or otherwise colored to create a wide range of potential colors for the outer button cover component  1312 , the color of which can be different than the color of the outer layer  1324 , which may also be dyed or otherwise colored separately. While an optional microfiber lining may be included if desired, the outer layer  1324  can alternatively wrap around the internal layer  1326  in a continuous fashion to form an inner layer of the accessory case  1300 . The outer layer  1324  can also have different openings at its outer and inner layers to accommodate the button cover  1310 . As shown, the opening at the inner layer, or inner portion, of outer layer  1324  can be larger than the opening at the outer layer, or outer portion, that receives the outer button cover component  1312 , so as to minimize thickness stack up at the location of the outer button cover component  1312 . The button cover  1310  can also include several additional parts that are separate from the accessory case  1300 . In addition to the outer button cover component  1312 , a cosmetic label  1330  can be used to cover a backing plate  1332  and a fastener  1336 . The backing plate  1332  and the fastener  1336  may be used to attach the outer button cover component  1312  to the web region  1334  of the outer layer  1324 . Also, in some embodiments, the fastener  1336  includes a self-clinching fastener. 
       FIG. 14  illustrates a side cross-sectional close-up view of the button cover  1310  of the accessory case  1300  shown in  FIG. 13 , further showing additional features. Some features shown and described in  FIG. 14  may facilitate an attachment of the outer button cover component  1312  with the outer layer  1324 . The backing plate  1332  may be located over the opening at an inner surface of the outer layer  1324 . The backing plate  1332  may include steel and may include a thickness of about 0.2 mm, for example. The backing plate  1332  may include a first region  1338  that contacts the outer layer  1324  around the opening. The backing plate  1332  may also include a second region  1342  that extends into the opening and contacts a surface of the outer button cover component  1312 . Also, as shown, an edge of the outer layer  1324  is compressed between the first region  1338  of the backing plate  1332  and the outer button cover component  1312 . 
     The fastener  1336  may include an extension  1346  that extends into a cavity  1344  of the outer button cover component  1312 . The fastener  1336  may further include a flange  1348  extending around an outer peripheral portion of the fastener  1336 . The flange  1348  can include a size large enough to cover the opening and compress the second region  1342  of the backing plate  1332  against the outer button cover component  1312 . During assembly, the fastener  1336  can be compressed against the backing plate  1332  and into the cavity  1344 . Alternatively, the outer button cover component  1312  can be compressed at the cavity  1344  onto the backing plate  1332  and the fastener  1336 . For example, as shown in  FIG. 14 , when a compression force is applied to fit the outer button cover component  1312  onto the fastener  1336 , the outer button cover component  1312  (formed from a relatively soft metal, such as aluminum) can deform into an undercut region  1340  of the fastener  1336 . As a result, the outer button cover component  1312 , once deformed, can interlock with the fastener  1336  at the undercut region  1340 , thereby limiting or preventing removal of the outer button cover component  1312  from the fastener  1336 . A compression force of about 750 Newtons (“N”) can be used in either arrangement. The compression force can also cause the backing plate  1332  to deform from a more planar, or flat, shape into the stepped shape shown in  FIG. 14 , and can also cause the fastener  1336  and/or the internal walls of the cavity  1344  in the outer button cover component  1312  to deform. This can take place at a tapered region of the outer button cover component  1312 , for example, and can result in deformed materials that create a press fit attachment between the fastener  1336  and the outer button cover component  1312 . In some embodiments, the backing plate  1332  can be at least partially stepped as its original configuration. A cosmetic label  1330 , such as a polyethylene terephthalate (“PET”) film mask, can be adhered to the back of the backing plate  1332  and/or outer layer  1324 , so as to cover this attachment arrangement at an interior location of the button cover  1310 . In some embodiments, the fastener  1336  includes a PEM® fastener. 
     While these attachment features can function to affix the outer button cover component  1312  to the outer layer  1324  effectively, another feature can also be used to limit relative shifting between these parts. For example, the outer button cover component  1312  may include a first rib  1364  and a second rib  1366 , each of which extending from the outer button cover component  1312 . In some embodiments, the first rib  1364  and the second rib  1366  extend into the outer layer  1324  (when, for example, the outer layer  1324  includes leather) during the compressive assembly of button cover  1310 , thereby further affixing the outer button cover component  1312  to the outer layer  1324  and also preventing or limiting relative side-to-side shifting of these parts. 
     In addition to the foregoing attachment features, the outer button cover component  1312  may include grooves, such as a first groove  1368  and a second groove  1372 , or similar openings. These grooves can function to direct stresses toward these grooves during a finishing operations to, or performing a deformable attachment of, the outer button cover component  1312 . Such stresses caused by these processes can cause cracking and other imperfections to outer, or visible, surfaces of the outer button cover component  1312 . However, these cracks and imperfections can occur at or near the first groove  1368  and/or the second groove  1372  at a non-visible location(s) rather than at the more cosmetic and visible exterior surface of the outer button cover component  1312 . 
     When the fastener  1336  includes a self-clinching fastener, the button cover  1310  may include a relatively low profile. Other alternative arrangements can also be used to attach the outer button cover component  1312  with the outer layer  1324 . For example, in some embodiments (not shown), a threaded screw can be used to lock the outer layer  1324  to a threaded cavity in the outer button cover component  1312 . 
       FIG. 15  illustrates a cross-sectional view of an exemplary button cover region for multiple adjacent buttons on a protective accessory case according to various embodiments of the present disclosure. As shown, an electronic device  1550  may include multiple buttons, such as a first button  1552  and a second button  1554 . These buttons may provide controls for the electronic device  1550  including, but not limited to, volume up and volume down. In order to accommodate the buttons, the accessory case  1500  may include a dual button cover  1510 . In this regard, the dual button cover  1510  may include a first outer button cover component  1512  and a second outer button cover component  1514 . 
       FIG. 15  further shows the accessory case  1500  having a dual backing plate  1530 . As shown, the dual backing plate  1530  includes a first backing plate  1532  and a second backing plate  1534  for the first outer button cover component  1512  and the second outer button cover component  1514 , respectively. The first backing plate  1532  can be substantially similar to the second backing plate  1534 . Also, the first backing plate  1532  can be separate from, but secured with, the second backing plate  1534  by a connector  1536 . Further, each of the first backing plate  1532  and the second backing plate  1534  may include a dimensional difference from that of the connector  1536 . For example, while each of the first backing plate  1532  and the second backing plate  1534  may include a thickness of approximately 0.2 mm, the connector  1536  may include a thickness of approximately 0.1 mm. This reduced thickness at connector  1536  can allow the first backing plate  1532  to remain coupled with the second backing plate  1534  while reducing undesirable “cross-talk” or carryover failures between the different buttons (such as the first button  1552  and the second button  1554 ) and button cover components (such as the first outer button cover component  1512  and the second outer button cover component  1514 ). Alternatively, the connector  1536  may include a spring geometry that coordinates alignment between the first backing plate  1532  and the second backing plate  1534  while reducing undesirable effects between buttons and button cover components. 
     In some embodiments, the first backing plate  1532 , the second backing plate  1534 , and the connector  1536  include a metal, such as steel or an alloy that includes steel. However, to further facilitate improved functionality of the first backing plate  1532  and the second backing plate  1534 , the connector  1536  may be formed from metal having a hardness that is less than that of the first backing plate  1532  and the second backing plate  1534 . In other words, the connector  1536  may be softer than the first backing plate  1532  and the second backing plate  1534 . One process for changing the hardness of the connector is to apply heat, by an annealing process, as a non-limiting example, to the connector  1536  while attaching the first backing plate  1532  and the second backing plate  1534  with the connector  1536  to form the dual backing plate  1530 . In particular, the process may include applying heat to the connector  1536  by an amount and/or a time greater than an amount and/or a time to the first backing plate  1532  and the second backing plate  1534 . 
     The dual backing plate  1530  is designed to assist in attaching both of the first outer button cover component  1512  and the second outer button cover component  1514  with a layer of the accessory case  1500 , such as an outer layer (not shown). Although two different backing plates, similar to the dual backing plate  1530 , could be used for the first button  1552  and the second button  1554 , the deformable nature of the dual backing plate  1530  during assembly and use can result in slight variations in the attachment depths, alignments, and orientation angles of the first outer button cover component  1512  and/or the second outer button cover component  1514 , when these outer button components are attached with the dual backing plate  1530 . For example, when the first backing plate  1532  is deformed differently from, or experiences a failure mode differently than, the second backing plate  1534 , then the overall appearance of the first outer button cover component  1512  can be different, or “off,” with respect to depth, alignment, and/or orientation angle as compared to the second outer button cover component  1514 . However, use of the dual backing plate  1530 , which forms a continuous structure by way of the connector  1536  attaching the first backing plate  1532  with the second backing plate  1534 , can result in coordinating an alignment between the first outer button cover component  1512  and the second outer button cover component  1514 , and eliminating or reducing offsets. 
     Alternatively, in some embodiments, the dual backing plate  1530  may include a steel or other metal that is relatively softer (e.g., half as hard) than that of the steel or other metal used for the backing plate  1332  (shown in  FIG. 14 ). In various embodiments, a given accessory case can include the backing plate  1332  (shown in  FIG. 14 ) that is relatively harder at single button cover location (such as the outer button cover component  1112 , shown in  FIG. 14 ) and also the dual backing plate  1530  that is relatively softer, with the dual backing plate  1530  located over a double button cover location on the accessory case, such as a location associated with the first outer button cover component  1512  and the second outer button cover component  1514 . 
       FIG. 16  illustrates a cross-sectional view of a fifth exemplary button cover region on a protective accessory case according to various embodiments of the present disclosure. As shown, an accessory case  1600  may include a button cover  1610  having an outer button cover component  1612 . In some embodiments, the outer button cover component  1612  includes a metal. The accessory case  1600  may also include an outer layer  1624  having an opening that receives the outer button cover component  1612 . In some embodiments, the outer layer  1624  includes leather. The outer layer  1624  can wrap around an internal layer  1626  (which may include plastic or a hard polycarbonate material, as non-limiting examples), and the outer layer  1624  and the internal layer  1626  can collectively form the accessory case  1600 . The accessory case  1600  may include a size and shape to accommodate an electronic device  1650  and a button  1652  of the electronic device  1650 . However, for purposes of simplicity and illustration, only a portion of the accessory case  1600  and only a portion of the electronic device  1650  are shown. 
     The button cover  1610  can be referred to as a “sandwich trim” arrangement, which includes some differing components with respect to the prior examples. For example, the button cover  1610  may include a trim element  1614  positioned around a perimeter of the outer button cover component  1612  and can be attached to the outer layer  1624 . In some embodiments, the trim element  1614  includes a metal. During a button actuation event in which a force is applied to of the outer button cover component  1612 , the trim element  1614  remains fixed against the outer layer  1624 , while the outer button cover component  1612  moves in a direction toward the button  1652  in order to actuate the button  1652 . 
     The button cover  1610  may further include a compliant membrane  1616  designed to facilitate movement of the outer button cover component  1612  by flexing during the button actuation event. The compliant membrane  1616  may include an elastomer material and can bond to various components. The elastomer material may extend into cavities, such as a first cavity  1618  and a second cavity  1620 , of the outer button cover component  1612  and contact exposed surfaces of the internal layer  1626  and a supporting element  1622 . In effect, the compliant membrane  1616  can be sandwiched between the outer button cover component  1612  and the supporting element  1622 . The compliant membrane  1616  can also mechanically stop against an extension of the trim element  1614  when the compliant membrane  1616  is not flexed. Accordingly, the compliant membrane  1616  may flex away from the trim element  1614  when the outer button cover component  1612  is actuated, which also causes actuation of the trim element  1614 . The compliant membrane  1616  may be bonded to these various components by an adhesive, as may be suitable. In some embodiments, the outer button cover component  1612  may include flanges (not shown) extending away from a surface of the outer button cover component  1612  that interfaces the compliant membrane  1616 . The flanges can create a hard mechanical stop against a surface of the trim element  1614  when the outer button cover component  1612  is in an un-actuated, or resting, position. Such flanges can also prevent removal of the outer button cover component  1612  from the accessory case  1600 . 
     The supporting element  1622  may include a plastic material. Also, the supporting element  1622  may be relatively rigid so as to limit or prevent moving or flexing, and can be coupled to the internal portion of the outer layer  1624  as shown, such that the outer layer  1624  also does not move or flex. Accordingly, compliance of leather or another soft material forming the outer layer  1624  is not needed in order for a button actuation event. 
       FIG. 17  illustrates a cross-sectional view of an alternative arrangement for the fifth exemplary button cover region according to various embodiments of the present disclosure. As shown, an accessory case  1700  may include a button cover  1710  having an outer button cover component  1712 . In some embodiments, the outer button cover component  1712  includes a metal. The accessory case  1700  may also include an outer layer  1724  having an opening that receives the outer button cover component  1712 . In some embodiments, the outer layer  1724  includes leather. The outer layer  1724  can wrap around an internal layer  1726  (which may include plastic or a hard polycarbonate material, as non-limiting examples), and the outer layer  1724  and the internal layer  1726  can collectively form the accessory case  1700 . The accessory case  1700  may include a size and shape to accommodate an electronic device  1750  and a button  1752  of the electronic device  1750 . However, for purposes of simplicity and illustration, only a portion of the accessory case  1700  and only a portion of the electronic device  1750  are shown. 
     Similar to the foregoing embodiment, the accessory case  1700  may include a trim element  1714  and a compliant membrane  1716 , which may include any material(s) previously described for a trim element and a compliant membrane, respectively. However, unlike the trim element  1614  (shown in  FIG. 16 ), the trim element  1714  in  FIG. 17  does not include extensions that extend to engage the compliant membrane  1716 . In this regard, the compliant membrane  1716  may not provide a mechanical stop for the trim element  1714 . During a button actuation event, the trim element  1714  remains fixed against the outer layer  1724 , while the outer button cover component  1712  and the compliant membrane  1716  move in a direction toward the button  1752 . The compliant membrane  1716  can again be formed from an elastomer material and can bond via adhesive to various components, and also extend into a first cavity  1718  and a second cavity  1720  of the outer button cover component  1712 . Also, the compliant membrane  1716  may engage the internal layer  1726  and a supporting element  1722 . 
       FIG. 18  illustrates a cross-sectional view of an alternative arrangement for the fifth exemplary button cover region according to various embodiments of the present disclosure. As shown, an accessory case  1800  may include a button cover  1810  having an outer button cover component  1812 . In some embodiments, the outer button cover component  1812  includes a metal. The accessory case  1800  may also include an outer layer  1824  having an opening that receives the outer button cover component  1812 . In some embodiments, the outer layer  1824  includes leather. The outer layer  1824  can wrap around an internal layer  1826  (which may include plastic or a hard polycarbonate material, as non-limiting examples), and the outer layer  1824  and the internal layer  1826  can collectively form the accessory case  1800 . The accessory case  1800  may include a size and shape to accommodate an electronic device  1850  and a button  1852  of the electronic device  1850 . However, for purposes of simplicity and illustration, only a portion of the accessory case  1800  and only a portion of the electronic device  1850  are shown. 
     The button cover  1810  may further include an inner button cover component  1820  that includes an insert portion  1822  positioned within a cavity  1832  of the outer button cover component  1812 . The inner button cover component  1820  can also include a flange  1828 , or backer portion, extending outward from the insert portion  1822 . This flange  1828  can also be used in combination with the outer button cover component  1812  to compress a web region  1834  of the outer layer  1824  therebetween, thereby attaching the outer layer  1824  to the outer button cover component  1812 . The inner button cover component  1820  may include a hard plastic or polycarbonate material, and can be attached to the outer button cover component  1812  by way of glue or other adhesive. Crush ribs (shown later) can also be used to facilitate the attachment between the inner button cover component  1820  and the outer button cover component  1812 , as detailed below. 
       FIG. 19A  illustrates an exploded view of various components from of an exemplary button cover region according to various embodiments of the present disclosure. The components shown and described may be alternative components suitable for use with the accessory case  1800  (shown in  FIG. 18 ). Accordingly, it should be understood that the button cover region may be used in conjunction with an accessory case in accordance with some described embodiments. As shown, the button cover  1910  may include an outer button cover component  1912 , as well as an inner button cover component  1940  configured to mate with or otherwise attach with the outer button cover component  1912 . In some embodiments, the outer button cover component  1912  includes a metal. The outer button cover component  1912  may include cavities, such as a first cavity  1928  and a second cavity  1932 , partially extending into the outer button cover component  1912 . The inner button cover component  1940  may include a first insert portion  1942  and a second insert portion  1944  designed to fit into the first cavity  1928  and the second cavity  1932 , respectively. In this regard, the inner button cover component  1940  may couple with the outer button cover component  1912 , and the inner button cover component  1940  may compress an outer layer of an accessory case (such as the outer layer  1824 , shown in  FIG. 18 ) against the outer button cover component  1912 . 
       FIG. 19B  illustrates a perspective of various alternative components according to various embodiments of the present disclosure. The components shown and described may be alternative components suitable for use with the accessory case  1800  (shown in  FIG. 18 ). As shown, a button cover  1950  may include an outer button cover component  1952  and an inner button cover component  1970  that mates with or otherwise attaches to the outer button cover component  1952 . Further, the button cover  1950  may take the form of a dual button cover that may be used with, for example, the dual backing plate  1530  (shown in  FIG. 15 ). 
       FIG. 20  illustrates a top plan view showing additional features for an exemplary button cover region according to various embodiments of the present disclosure. As shown, a button cover component  2040  may include a backer portion  2042  that includes a first insert portion  2044  and a second insert portion  2046 . The aforementioned insert portions are suitable for inserting into cavities on an associated outer button cover component (such as the first cavity  1928  and the second cavity  1932  of the outer button cover component  1912 , shown in  FIG. 19A ). Each insert portion may include several crush ribs. For example, the first insert portion  2044  includes a first set  2054  of crush ribs surrounding multiple walls of the first insert portion  2044 , and the second insert portion  2046  includes a second set  2056  of crush ribs surrounding multiple walls of the second insert portion  2046 . When the first insert portion  2044  and the second insert portion  2046  are each inserted into a cavity of an outer button cover component, these crush ribs of each insert portion can deform to facilitate an interference fit, or press fit, with the inner walls of the cavity. As part of forming the interference fit, the walls of the cavity may also be deformed by the crush ribs. These crush ribs can be used to attach the button cover component  2040  to an associated outer button cover component. Also, glue or another adhesive may be used to facilitate the attachment. 
       FIG. 21A  illustrates a front perspective of exemplary coupling features for a button cover region according to various embodiments of the present disclosure. As shown, an arrangement may include an outer button cover component  2112  designed to attach with an inner button cover component  2120 . The outer button cover component  2112  may include a rigid material, such as metal. The inner button cover component  2120  may include nylon, hard plastic, or a polycarbonate material, as non-limiting examples. Also, the inner button cover component  2120  may include multiple insert portions, such as a first insert portion  2122  and a second insert portion  2124 , that are coupled by a flange  2126  that provides a backing for the first insert portion  2122  and the second insert portion  2124 . 
     The outer button cover component  2112  may include a first cavity  2114  and a second cavity  2116  designed to receive the first insert portion  2122  and the second insert portion  2124 , respectively. In this regard, the first insert portion  2122  and the second insert portion  2124  can be configured to secure in a “snap fit” arrangement within the first cavity  2114  and the second cavity  2116 . This will be shown below. 
       FIG. 21B  illustrates a cross-sectional view of the components of  FIG. 21A , showing the outer button cover component  2112  attached to the inner button cover component  2120 . As shown, the first insert portion  2122  is secured with the first cavity  2114 . In particular, the first insert portion  2122  may include a first tab  2136  and a second tab  2138  designed to provide the snap fit arrangement with a first recess  2146  and a second recess  2148 , respectively, with the first recess  2146  and the second recess  2148  formed in the first cavity  2114 . Although not shown, it should be noted that the second insert portion  2124  (shown in  FIG. 21A ) may include tabs that secure in recesses of the second cavity  2116  (shown in  FIG. 21A ) in a manner similar to what is shown in  FIG. 21B . The snap fit arrangement can help to attach the outer button cover component  2112  with the inner button cover component  2120 , and can be used in addition to a glue or adhesive, crush ribs, and/or other mechanical features that facilitate such an attachment. 
       FIG. 22  illustrates a flowchart of an exemplary method for forming a protective accessory case for a portable electronic device according to various embodiments of the present disclosure. In particular, the exemplary method involves attaching a separate outer button cover component to an accessory case. Of course, other steps and features may alternatively or also be part of forming an accessory case. The flowchart  2200  can start at a process step  2202 , where layers of different materials can be adhered together. This can involve, for example, adhering an outer layer to an internal layer to form the accessory case, with the outer layer including leather or silicone, and the internal layer including a polycarbonate material. An optional microfiber lining may also be adhered to the internal layer in some embodiments. As noted above, the internal layer can be a more rigid and firm material, such as a hard plastic, while the outer layer can be a softer and aesthetically pleasing material to be handled regularly by a user, such as silicone or leather. 
     At process step  2204 , an opening can be created through the layers of the accessory case. This opening may go through all of the layers, and can be sized for the acceptance of a button cover used to cover a button of an electronic device positioned in the accessory case. At process step  2206 , an outer button cover component can be placed over the opening at an outer surface of the accessory case. In various embodiments, this outer button cover component may include anodized aluminum. In other words, the outer button cover may include a material that is different from that of the outer layer. At process step  2208 , a backing plate or shim can be placed over the opening at an inner surface of the accessory case. The inner surface may also be formed from leather. Alternatively, the inner surface may include a microfiber lining at this location. 
     At process step  2210 , a fastener can be inserted through a center opening in the backing plate and into a cavity at the rear surface of the outer button cover component. The fastener may include a self-clinching fastener, such as a PEM® fastener. At process step  2212 , the fastener can be compressed against or to the backing place and into the cavity of the outer button cover component. This can result in an interference fit between the fastener and the outer button cover component, such as where one or both of the fastener and the outer button cover component deform and press into each other. Further, the edge of one of the layers of the accessory case can be compressed between the backing plate and the back of the outer button cover component as a result of compression step at process step  2212 . In addition, the backing plate can be compressed between the fastener and the back of the outer button cover component at another location. The overall result is that the button cover is now affixed to the at least one of the layers of the accessory case. 
     It should be noted that not every step in the flowchart  2200  is always necessary, and that further steps not set forth herein may also be included. For example, added process steps that involve cutting or shaping the accessory case may be included. Also, steps that provide a camera opening may also be included. Furthermore, the exact order of steps may be altered as desired, and some steps may be performed simultaneously.
