Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a continuation of U.S. application Ser. No. 15/656,593, filed on Jul. 21, 2017, entitled “SINGLE PIECE CASE WITH A BATTERY AND A HINGE”, which is a continuation of U.S. application Ser. No. 14/815,352, filed Jul. 31, 2015, of the same title, now U.S. Pat. No. 9,735,595, issued on Aug. 15, 2017, the contents of all of which are incorporated by reference herein in their entirety for all purposes. 
    
    
     FIELD 
     The described embodiments relate generally to accessory devices. In particular, the present embodiments relate to a unitary accessory device having a hinge feature that allows the unitary accessory device to pivot and bend at the hinge feature allowing for insertion and extraction of an electronic device. 
     BACKGROUND 
     An accessory device for an electronic device is generally known in the art. Accessory devices can be used as a protective cover for the electronic device as well as provide an aesthetic appearance. Further, some accessory devices may include a power supply designed to provide electrical current to the electronic device. Also, typical accessory devices include at least one layer of material disposed across the entire accessory device. For example, a region of the accessory device designed to receive the electronic device may include a rigid polymeric material, such as plastic, disposed across the entire region. This offers a continuous, uniform protection to the electronic device. 
     In order to insert or extract the electronic device in a manner that does not damage the electronic device, a user is generally required to detach one structural feature of the accessory device from another structural feature. This allows for a straight insertion or extraction of the electronic device. However, an accessory device with two (or more) structural features may lead to losing or misplacing at least one of the structural features. 
     One solution may be to pull the electronic device from the accessory device at an angle. However, an angular extraction of an electronic device from an accessory device can lead to other issues. For example, when the accessory device includes the power source, a connector, or plug, must be inserted into the electronic device. The angular extraction causes a bending moment on the connector that may cause the connector to break off from the accessory device and remain inside the electronic device. 
     SUMMARY 
     In one aspect, a unibody accessory device suitable for use with an electronic device is described. The unibody accessory device may include a unitary structure having a size and a shape in accordance with the electronic device. The unitary structure may include a first region and a second region that combine to carry the electronic device. In some embodiments, the first region, in response to a force applied to the first region, pivots to allow an insertion event or an extraction event of the electronic device. 
     In another aspect, an accessory device suitable for use with an electronic device is described. The accessory device may include a first sidewall and a second sidewall that combine to retain the electronic device. The first sidewall may extend into a first region and a second region. The accessory device may further include a hinge feature hidden from view. The hinge feature may be positioned between the first region and the second region. The accessory device may further include a power supply. The accessory device may further include a connector disposed in the second region and configured to electrically connect the electronic device with the power supply. In some embodiments, the first region pivots at the hinge feature in response to a force applied to the first region to define a bent configuration of the first region with respect to the second region. Further, the bent configuration may allow the electronic device to be 1) inserted between the first sidewall and the second sidewall in a direction toward the connector, and 2) extracted from the first sidewall and the second sidewall in a direction away from the connector. 
     In another aspect, a method for forming a unibody accessory device having a hinge feature that facilitates an insertion event and an extraction event of an electronic device is described. The method may include securing a first region of the unibody accessory device with the hinge feature. The method may further include securing a second region of the unibody accessory device with the hinge feature. The method may further include forming a sidewall along the first region and the second region. In some embodiments, a force applied to the first region pivots at the hinge feature and bends the sidewall at the hinge feature to allow the insertion event or the extraction event. 
     Other systems, methods, features and advantages of the embodiments will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description and this summary, be within the scope of the embodiments, and be protected by the following claims.

     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 an accessory device used with an electronic device. The accessory device may include a rigid shell formed from a polymeric material, such as a thermoplastic material. A molding process, such as compression molding or injection molding, may form the rigid shell. A relatively softer material, such as silicone, may surround the rigid shell. Further, the accessory device may include a hinge feature that allows the accessory device to pivot or bend in some locations of the accessory device. The hinge feature may be formed from a relatively flexible material, such as an elastomeric material. Also, the hinge feature may be formed in a manner such that the hinge feature is hidden from view to a user. This may be due in part to a molding process, and/or by an additional layer, such as a fabric layer (including microfiber), overlaying the hinge feature. The hinge feature is designed to allow for insertion of the electronic device into the accessory device, as well as extraction of the electronic device from the accessory device. 
     Further, the accessory device may include a first region and a second region. In some embodiments, the first region is generally associated with a region that secures an uppermost region of the electronic device, and the second region is generally associated with a region that secures a region other than the uppermost region of the electronic device. The first region and the second region may include several sidewalls designed to retain the electronic device. The hinge feature may be positioned between the first region and the second region. In this manner, the first region, for example, may pivot at the hinge feature and the electronic device can slide into or out of the accessory device. 
     The hinge feature offers several advantages. For example, in some embodiments, the sidewalls include a rigid polymeric material (or materials) designed to enhance structural support of the electronic device. In these embodiments, the sidewalls do not easily bend and accordingly, insertion or extraction of the electronic device via the sidewalls should be avoided. However, the hinge feature allows the first region to pivot out of the way during an insertion event or an extraction event, and the electronic device can slide into or out of the electronic device, respectively, with relative ease. Once the electronic device is into or out of the accessory device, the first region can bend or pivot back to its original or initial position and cover a portion of the electronic device. 
     In addition, the hinge feature allows for a unitary or unibody accessory device. In other words, when fully assembled, the accessory device including the hinge feature is not designed to include two or more separable parts or components. Traditional accessory devices may include multiple, separable components which increases the risk of losing or misplacing one or more of the separable components. 
     Further, in some embodiments, the accessory device includes a power source, or battery, designed to provide electrical current to a battery of the electronic device and increase a charge level, or battery power level, of the battery. In order to supply electrical current, the accessory device may include a connector, or plug, designed to electrically connect the power source with the electronic device, and in particular, the battery. If the electronic device is inserted into or extracted from the electronic device at an angle greater than zero, the electronic device may impose a bending moment to the connector causing damage to the connector or even breaking the connector off inside the electronic device. However, the hinge feature allows the first region to bend or pivot (in a manner previously described) and allows the electronic device to enter or exit from the accessory device without providing a bending moment to the connector. In other words, the electronic device may slide between the sidewalls directly toward or away from the connector at an angle of approximately zero with respect to the connector. Alternatively, this may be characterized as the electronic device being inserted into or extracted from the accessory device in a direction approximately parallel to the accessory device or one or more features of the accessory device, such as the hinge feature or the power supply of the accessory device. 
     Although the hinge feature is described as including an elastomeric material, several other materials designed to bend or flex in response to a force may be used. For example, the hinge feature may include a metal hinge feature for additional support. Also, in some embodiments, the metal hinge feature is designed to bend into two positions, one of which may be associated with a bent or pivoted configuration of the first region allowing movement of the electronic device relative to the accessory device. In some embodiments, the hinge feature includes interlocking pieces designed to fit like a puzzle piece. For example, the first region may include a first piece that mates with a second piece in a location associated with the hinge feature. The first region may be designed to receive a force that decouples the first piece with the second piece. The first region may then receive an additional force that pivots the first region to allow the electronic device to be inserted into or extracted from the accessory device. 
     Also, in order to further prevent damage to the connector and/or electronic device, the accessory device may further include a second hinge feature located proximate to the connector. This allows the connector to pivot with the electronic device. 
     Still, the accessory device may include other means for inserting and extracting the electronic device. For example, the first region of the accessory device, corresponding to the uppermost region of the electronic device, may include several small cuts or slits in a rigid shell. This allows for additional movement of the accessory device proximate to the small cuts. However, the small cuts are hidden from view by a layer (for example, silicone) molded over the small cuts. 
     These and other embodiments are discussed below with reference to  FIGS. 1-25 . 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  suitable for use with an electronic device (not shown), in accordance with the described embodiments. As shown, the accessory device  100  includes a first region  102  and a second region  104 . The first region  102  may be designed to receive an uppermost region of an electronic device, and the second region  104  may be designed to receive a remaining region (or regions) of the electronic device. Accordingly, the first region  102  and the second region  104  can combine to define a receptacle region that carries the electronic device. Also, the accessory device  100  may further include a hinge feature  106  positioned between the first region  102  and the second region  104 . A fabric layer, such as a microfiber layer, may overlay the hinge feature  106  (shown as dotted lines) and the hinge feature  106  is hidden from view. In some embodiments, the hinge feature  106  is formed form a metal. In the embodiment shown in  FIG. 1 , the hinge feature  106  includes an elastomeric material designed to allow the first region  102 , in response to a force applied to the first region  102 , to pivot or bend at the hinge feature  106  and allow the electronic device to slide into or out of the accessory device  100 . Also, the accessory device  100  may include several sidewalls, such as a first sidewall  112  and a second sidewall  114  opposite the first sidewall  112 , designed to further retain the electronic device. Both the first sidewall  112  and the second sidewall  114  may extend along the first region  102  and the second region  104 . Also, when the first region  102  pivots at the hinge feature  106 , an electronic device may slide between a portion of the first sidewall  112  and the second sidewall  114  (corresponding to the second region  104 ) so that the electronic device may be inserted into or extracted from the accessory device  100 . This will be described and shown in detail below. 
     The accessory device  100  may further include a power supply disposed in a rear portion  108  of the accessory device  100 . In some embodiments, the power supply includes one or more battery cells designed to retain an electrical charge. The accessory device  100  includes a port  122  designed to receive a connector that, when coupled to a power source (such as an electrical outlet, not shown), provides electrical current in order to charge the power supply. The accessory device  100  further includes a connector  124 , or port, designed to electrically connect the electronic device with the power supply. In this manner, the power source can recharge a battery in the electronic device when the electronic device is electrically coupled with the connector  124 . 
     Also, as shown, the hinge feature  106  is designed to extend into both the first sidewall  112  and the second sidewall  114 . This may allow for greater stability for the hinge feature  106 . However, in other embodiments, the hinge feature  106  is disposed only on a base portion  116  of the accessory device  100 . Also, in some embodiments, the hinge feature  106  extends through the sidewalls in a location proximate one or more protruding features, such as a first protruding feature  132  and a second protruding feature  134 . The protruding features are designed to align with input features, or buttons, of the electronic device such that when a force is applied to a protruding feature, a button corresponding to the protruding feature is depressed to input a gesture to the electronic device. 
     The accessory device  100  may further include several openings. For example, as shown in  FIG. 1 , the accessory device  100  includes a first opening  142  designed to open to a camera and lens of the electronic device. Also, the accessory device  100  may further include a second opening  144  designed to open to an input feature, such as a switch, of the electronic device. Further, the accessory device  100  may include a third opening  146  designed to allow an input device, such as an audio headset, to electrically couple with the electronic device. Also, the base portion  116  of the accessory device  100  may include a fourth opening  148  designed to allow visible light from a light source, such as a light-emitting diode (LED) (not shown). The LED light may provide an indication of the charge level of the power source in the accessory device  100 . For example, LED may emit green light when the power source is fully charged. Further, LED may switch to an orange, or amber, color when the power source is charging. The accessory device  100  may also include a fifth opening  152  and a sixth opening  154 . The fifth opening  152  is designed to allow sound to travel to a microphone opening of an electronic device, while the sixth opening  154  is designed to allow sound to travel from an audio speaker of the electronic device. 
     Also, the accessory device  100  may be referred to as a unibody accessory device in that the accessory device  100 , when fully assembled, does not include a part or component detachable with respect to another part or component. 
       FIG. 2  illustrates a front view of the accessory device  100  shown in  FIG. 1 . As shown, the hinge feature  106  extends across the accessory device  100  from the first sidewall  112  to the second sidewall  114 . Also, the connector  124  may be electrically coupled with a power source using integrated circuits  162  disposed in the second region  104  and generally hidden from view. The integrated circuits  162  may further include one or more circuits to process electrical signals, such as data transmission or electrical power, from an electrical outlet electrically connected to the accessory device via the port  122 . Further, the integrated circuits  162  may include one or more circuits to process electrical signals generated from a headset electrically connected to the accessory device  100  via the third opening  146 .  FIG. 3  illustrates a rear view of the accessory device  100  shown in  FIG. 1 . As show, the integrated circuits  162  are electrically coupled with the power source  168  disposed in a rear portion of the accessory device  100  such that the power source  168  is hidden from view. 
       FIG. 4  illustrates an exploded view of the accessory device  100  shown in  FIG. 1 . For purposes of simplicity, the integrated circuits previously described are not shown. The accessory device  100  may include a rigid layer  202  formed from a polymeric material, such as a plastic or thermoplastic. The rigid layer  202  generally defines the shape of the accessory device  100  and provides structural support to the accessory device  100 . A molding process, such as compression molding or injection molding, both of which include a molding core and a mold cavity (not shown), may be used to form the rigid layer  202 . As shown, the rigid layer  202  includes several fastener receptacles, such as a first fastener receptacle  204  and a second fastener receptacle  206 . Each of the fastener receptacles is designed to receive a fastener that secures one or more components with the rigid layer  202 . 
     However, the rigid layer  202  does not extend to all locations of the accessory device  100 . For example, the hinge feature  106  previously described is located in a region generally not associated with the rigid layer  202 . Accordingly, the hinge feature  106  may separate the rigid layer  202  into a first rigid portion  212  and a second rigid portion  214 . Further, the hinge feature  106  may be made from a first material (such as an elastomeric material) and the rigid layer  202 , which includes the first rigid portion  212  and the second rigid portion  214 , may be made from a second material (such as a thermoplastic material) different from the first material. Also, as shown in  FIG. 4 , a soft layer  222  may surround and cover and exterior region of the rigid layer  202  and the hinge feature  106 . In some embodiments, the soft layer  222  includes a silicone material over molded to the rigid layer  202 . 
     In some locations, the sidewalls include both the rigid layer  202  and the soft layer  222 . For example,  FIG. 5  illustrates a cross sectional view of the accessory device  100  along Section A, shown in  FIG. 4 . As shown, the soft layer  222  surrounds the rigid layer  202 . However, in other locations, the sidewalls include only the material defining the hinge feature  106  and the soft layer  222 . For example,  FIG. 6  illustrates a cross sectional view of the accessory device  100  along Section B, shown in  FIG. 4 . As shown, the soft layer  222  surrounds the hinge feature  106 . The rigid layer  202  terminates such that the hinge feature  106  and the soft layer  222  define the sidewall. In some embodiments, the material defining the hinge feature  106  is formed from an elastomeric material. Still, in other locations, the sidewalls include only the soft layer  222 . For example,  FIG. 7  illustrates a cross sectional view of the accessory device  100  along Section C, shown in  FIG. 4 , showing the sidewall made of only the soft layer  222 . This allows for additional flexibility and bending of the accessory device  100 , and in particular, bending of the sidewall. 
     Returning to  FIG. 4 , the accessory device  100  further includes a power source  168  disposed in an opening  218  (when the accessory device  200  is fully assembly) defined by the rigid layer  202 . In some embodiments, the power source  168  includes a battery cell. A battery can  172  designed to provide protection to the power source  168  may surround the power source  168 . The battery can  172  may include several openings, each of which is designed to receive a fastener and couple with a fastener receptacle of the rigid layer  202 . Both the power source  168  and the battery can  172  are designed to fit into the opening  218  of the rigid layer  202  and accordingly, may be hidden from view due in part by the rigid layer  202 , the soft layer  222 , and the fabric layer  272  (discussed later). Also, the accessory device  100  may further include a light transmission feature  232  positioned in a block  234 . The block  234  may be designed to receive the light transmission feature  232  and a light source, such as a light-emitting diode (not shown). In this manner, the light source may transmit light through the light transmission feature  232 , which acts as a light guide panel, and the light transmission feature  232  allows the light to exit the accessory device  100  through one or more openings. The light source may indicate an electrical charge level of the power source  168 . For example, the light source may emit, for example, a green color to denote “100 percent charge” of the power source. Alternatively, the light source may emit a different color, such as orange or amber, to denote the power source  168  is still charging. 
     The accessory device  100  may further include a lid feature  242  designed to cover and protect the power source  168 . The lid feature  242  may include several openings, such as a first opening  244  and a second opening  246 . Each of the openings is designed to receive a fastener that secures one or more components with the rigid layer  202 . However, the lid feature  242  may further include an opening  248  aligned with the light transmission feature  232 . Also, the accessory device  100  may include several fasteners, such as a first fastener  254  and a second fastener  256 . Each of the fasteners is designed to extend through an (outer) opening of the lid feature  242 , an opening of the battery can  172 , and a fastener receptacle of the rigid layer  202 . 
     The accessory device  100  may further include a camera trim  262  designed to provide an opaque layer. The camera trim  262  is located around an opening of the accessory device  100  (such as the first opening  142 , shown in  FIG. 1 ). In this manner, when an electronic device having a camera is installed in the accessory device  100 , any unwanted light received during an image capture event using the camera may be blocked by the camera trim  262 . The camera trim  262  may be disposed in a recessed portion  216  of the second rigid portion  214 . 
     The accessory device  100  may further include a fabric layer  272  designed to provide a non-abrasive surface that does not scratch or damage an electronic device installed in the accessory device  100 . In some embodiments, the fabric layer  272  includes a microfiber layer. The fabric layer  272  includes an opening  274  aligned with the opening  248  of the lid feature  242 . This allows light to exit from the accessory device  100 . The light may be visible to a user when an electronic device is not installed in the accessory device  100 . 
       FIGS. 8-11  illustrate a process for extracting an electronic device  310  from an accessory device  300 , in accordance with the described embodiments. The accessory device  300  may include any features previously described for an accessory device. Also, the electronic device  310  may be mobile communication device, such as a smartphone or a tablet device. 
       FIG. 8  illustrates a side view of the accessory device  300  that includes an electronic device  310 , showing a force applied to a first region  302  of the accessory device  300 . As shown, a thumb  352  of a user is capable of providing the force to the first region  302  generally in a direction denoted by an arrow  362 .  FIG. 9  illustrates a side view of the first region  302  of the accessory device  300  pivoting at a hinge feature  306  within in the accessory device  300 , with the first region  302  bending in response to the force applied. As shown, with sufficient force supplied by the thumb  352 , the first region  302  is removed from the electronic device  310 . Also, a portion of the sidewalls located in the first region  302  may bend. For example, in  FIG. 9 , a portion of a sidewall  314  bends when the first region  302  pivots.  FIG. 10  illustrates a side view of the electronic device  310  being removed from the accessory device  300  in response to a second force, denoted by an arrow  372 . This may include the electronic device  310  being extracted from the sidewalls of the accessory device  300 . The second force may be referred to an extraction force used to remove the electronic device  310  from the accessory device  300 . As shown, the extraction force is provided by a thumb  352  and a finger  354  (of a user) grasping the electronic device  310  and pulling the electronic device away from the accessory device  300 . Further, the arrow  372  denotes a straight or linear extraction of the electronic device  310 , rather than an angled extraction (at an angle greater than zero). In this manner, the electronic device  310  does not provide a bending moment to any components of the accessory device, such as a connector  124  (shown in  FIG. 1 ), and accordingly, does not cause damage to the accessory device  300 .  FIG. 11  illustrates a side view of the electronic device  310  removed from the accessory device  300 , with the first region  302  returned to its initial position. The “initial position” may be referred as a straight or linear configuration. 
     It will be appreciated that a generally similar procedure may be used to insert the electronic device  310  into the accessory device  300 . For instance, a force may be applied to the first region  302  followed by a force applied to the electronic device  310  in a direction opposite the arrow  372  (shown in  FIG. 10 ) to insert the electronic device  310  into the accessory device  300 . 
       FIG. 12  illustrates an isometric view of an alternate embodiment of an accessory device  400  having openings in the sidewalls, in accordance with the described embodiments. For example, the accessory device  400  may include a first sidewall  412  having a first opening  422  and a second sidewall  414  having a second opening  424 . The first opening  422  and the second opening  424  may allow a first region  402  to pivot or bend with respect to a second region  404 . In some embodiments, a hinge feature  406  is included. In addition to these features, the accessory device  400  may include any features previously described for an accessory device. 
       FIG. 13  illustrates a rear view of an alternate embodiment of an accessory device  500  having a hinge feature  506  formed from a metal, in accordance with the described embodiments. As shown, the hinge feature  506  is embedded in one or more layers of the accessory device  500 . The hinge feature  506  allows a first region  502  to pivot or bend with respect to a second region  504 , in order to insert or extract an electronic device in a manner previously described. In addition to these features, the accessory device  500  may include any features previously described for an accessory device. 
       FIG. 14  illustrates an isometric view of an alternate embodiment of a hinge feature  606  suitable for use in an accessory device, in accordance with the described embodiments. In some embodiments, the hinge feature  606  is formed from a metal. The hinge feature  606  is capable of bending from a first position (shown in  FIG. 14 ) to a second position (not shown) by applying a force to a wing feature  616  of the hinge feature  606 . In this regard, the hinge feature  606  may be referred to as a “bi-stable hinge” in that the first position and the second position of the wing feature  616  define two stable positions of the hinge feature  606 . 
       FIG. 15  illustrates a side view of an embodiment of an accessory device  600  that includes the hinge feature  606  shown in  FIG. 14 . As shown, the hinge feature  606  is in the first position. However,  FIG. 16  illustrates a side view of the accessory device  600  shown in  FIG. 15 , with a first region  602  pivoting in response to a force applied to the first region  602 . The force is applied in a direction denoted by an arrow  662 . The hinge feature  606  is in the second position, and an electronic device (not shown) may be inserted into or extracted from the accessory device  600 . 
       FIG. 17  illustrates an isometric view of an alternate embodiment of an accessory device  700  having an alternate embodiment of an interlocking feature  706 , in accordance with the described embodiments. The fabric layer is removed for purposes of illustration. As shown, the interlocking feature  706  may couple a first region  702  with a second region  704 . The first region  702  may include a first extension  712  and a second extension  714 , both of which are inserted into and interlocked with the interlocking feature  706 . However, the extensions are designed to decouple with the interlocking feature  706 . 
       FIG. 18  illustrates a side view of an embodiment of an accessory device  700  that includes the interlocking feature  706  shown in  FIG. 17 . As shown, when a force is applied to the first region  702  in a direction of an arrow  762 , the first extension  712  and the second extension  714  (shown in  FIG. 17 ) disengage from the interlocking feature  706 .  FIG. 19  illustrates a side view of the accessory device shown in  FIG. 18 , with a first region  702  bending in response to a second force applied to the first region  702 . The second force may be in a direction of an arrow  772 . In this position, the accessory device  700  is capable of receiving an electronic device, or the accessory device  700  may allow the electronic device to be removed. 
       FIG. 20  illustrates an isometric view of an alternate embodiment of an accessory device  800  having an opening  808  in a sidewall  816 . This may allow other sidewalls, such as a first sidewall  812  and/or a second sidewall  814  to bend or flex to allow an electronic device (not shown) to be inserted into or extracted from the accessory device  800 . 
     Other embodiments (not shown) may be used. For example, an accessory device previously described may include a first hinge feature and a second hinge feature. The second hinge feature may be located proximate to a connector (such as a connector  124 , shown in  FIG. 1 ). This allows for additional flexibility and reduces the likelihood of damage to the accessory device or an electronic device. Further, a sidewall in a first region (such as the first region  102 , shown in  FIG. 1 ) may include several cuts or slights in a rigid portion (such as the second rigid portion  214 , show in  FIG. 4 ). The cuts may be hidden from view by a soft layer (such as the soft layer  222 , show in  FIG. 4 ). This allows a sidewall in the first region to include additional flexibility to allow an electronic device (not shown) to be inserted into or extracted from the accessory device. 
     The previous embodiments describe an accessory device having a connector designed to engage an opening in an electronic device in order to provide power to and charge a battery in the electronic device. This is generally referred to a “wired charging” configuration. However, several alternate techniques may be used to charge the accessory device as well as the electronic device without the wired charging configuration. 
     For example,  FIG. 21  illustrates an isometric view of an alternate embodiment of an electronic device  950  and accessory device  900  suitable for use with charging the electronic device  950 , in accordance with the described embodiments. The accessory device  900  may include metal contacts designed to engage metal contacts of the electronic device  950 . For example, the accessory device  900  may include first metal contacts  910  disposed on a base portion  916  of the accessory device  900 . The electronic device  950  may include first metal contacts  960  disposed on a rear portion of the electronic device  950  and designed to engage the first metal contacts  910  of the accessory device  900  when the electronic device  950  is inserted in the accessory device  900 . The first metal contacts  910  of the accessory device  900  are electrically coupled with a power source (not shown) disposed in an opening of the accessory device  900  in a manner previously described (see  FIG. 4 ). Further, the first metal contacts  960  are electrically coupled with a battery disposed in the electronic device  950 . In this manner, when the first metal contacts  960  of the electronic device  950  engage the first metal contacts  910  of the accessory device, the accessory device  900  is designed to supply power in the form of electrical current from the power source in the accessory device  900  to the battery of the electronic device  950  via the metal contacts of the respective devices. 
     It will be appreciated that the first metal contacts  910  may be disposed anywhere along the base portion  916 , and may include any number of metal contacts. Typically, the first metal contacts  910  may be include a corresponding number of metal contacts as the number of the first metal contacts  960  of the electronic device  950 . Also, the first metal contacts  910  be disposed at a corresponding location as the first metal contacts  960  of the electronic device  950 . Also, any one or more of the first metal contacts  910  of the accessory device  900  may be designed to transmit other electrical signals, such as data transmission, to a corresponding metal contact (or contacts) of the first metal contacts  960 , with those metal contacts of the first metal contacts  960  designed to receive the data transmission. Data transmission may include, for example, media files (audio, video) transmitted from another electronic device (not shown). 
     The accessory device  900  may include second metal contacts  920  on a sidewall  912  of the accessory device  900 . Also, the electronic device  950  may include second metal contacts  970  on a sidewall  972  of the electronic device, and designed to engage the second metal contacts  920  of the accessory device  900  when the electronic device  950  is inserted in the accessory device  900 . Accordingly, the second metal contacts  920  may be include a corresponding number and be disposed at a corresponding location as the second metal contacts  970  of the electronic device  950 . The second metal contacts  920  may be designed to provide the same function (or functions) as that of the first metal contacts  910 . Also, in some embodiments, the accessory device  900  includes the first metal contacts  910  only at the base portion  916 . In other embodiments, the accessory device  900  includes the first metal contacts  910  only at the sidewall  912 , or any of the sidewalls of the accessory device  900 . 
     Also, the accessory device  900  may include any embodiment of a hinge feature  906  similar to those previously described, such as a hinge feature  106  (shown in  FIG. 1 ). This allows the accessory device  900  suitable for use with an extraction (or insertion) of the electronic device  950  in a manner similar to that shown in  FIGS. 8-11 . Also, the accessory device  900  may be formed by and may include any means previously described to facilitate actuating or pivoting a first region  902  of the accessory device  900  with the respect to a second region  904  of the accessory device  900 . 
       FIG. 22  illustrates an isometric rear view of the accessory device  900  shown in  FIG. 21 . As shown, the accessory device  900  include third metal contacts  930  electrically coupled with a power source disposed in the accessory device  900 , and designed to engage and electrically couple with a charging station (not shown). The charging station may deliver power in the form of electrical current to the power source, via the third metal contacts  930 , in order to charge the power source. In some embodiments, at least some of the third metal contacts  930  are designed to receive data transmission which may be passed to the electronic device  950  (shown in  FIG. 21 ) via the metal contacts (shown in  FIG. 21 ) of the accessory device  900  engaged with the metal contacts of the electronic device  950 . Further, the third metal contacts  930  may be located anywhere along the rear portion  932  and may include any number of metal contacts. 
       FIG. 23  illustrates an isometric view of an alternate embodiment of an electronic device  1050  and accessory device  1000  suitable for use with charging the electronic device  1050 , in accordance with the described embodiments. The accessory device  1000  and the electronic device  1050  may combine to form a charging system, such as an inductive charging system. As shown, the accessory device  1000  may include a first coil feature  1010  located on a base portion  1016 , and the electronic device  1050  may include a second coil feature  1060 . The first coil feature  1010  and the second coil feature  1060  may each include a wire would several times around, for example, a metal core feature. In this manner, when the electronic device  1050  is disposed in the accessory device  1000 , the first coil feature  1010  and the second coil feature  1060  may combine to form part of an inductive charging system designed to supply power in the form of electrical current from a power source in the accessory device  1000  to a battery disposed in the electronic device  1050 . Further, the first coil feature  1010  may receive electrical current form an external source (such as an electrical outlet) and transfer at least some of the electrical current to the second coil feature  1060 , which may provide an electrical current used to charge battery in the electronic device  1050 . The metals cores, one of which is disposed in the accessory device  100  and wound by the first coil feature  1010 , and the other disposed in the electronic device  1050  and wound by the second coil feature  1060 , may provide a means for transferring the electrical current from the first coil feature  1010  to the second coil feature  1060 . 
     Also, the accessory device  1000  may include any embodiment of a hinge feature  1006  previously described, such as a hinge feature  106  (shown in  FIG. 1 ). This allows the accessory device  1000  suitable for use with an extraction (or insertion) of the electronic device  1050  in a manner similar to that shown in  FIGS. 8-11 . Also, the accessory device  1000  may be formed by and may include any means previously described to facilitate actuating or pivoting a first region  1002  of the accessory device  1000  with the respect to a second region  1004  of the accessory device  1000 . 
       FIG. 24  illustrates an isometric rear view of the accessory device shown in  FIG. 23 . As shown, the accessory device  1000  may include a third coil feature  1030  disposed on a rear portion  1032  of the accessory device  1000  and electrically coupled with a power source disposed in the accessory device  1000 . The third coil feature  1030  may include a wire would several times around a metal core feature. Also, the third coil feature  1030  is designed to pair with an additional coil feature and metal core (not shown) used to form an inductive charging station that provides power in the form of electrical current in order to charge the power source disposed in the accessory device  1000 . 
     Other means for charging a power source in an accessory device may be used. For example, the charging means for the power source may include a photovoltaic (solar) panel, or panels, disposed on the accessory device designed transform light energy into electrical energy, with the electrical energy stored in the power source of the accessory device. Also, the accessory device may be designed to receive infrared light in order to charge the power source of the accessory device by infrared means. 
       FIG. 25  illustrates a flowchart  1100  showing a method for forming a unibody accessory device having a hinge feature that facilitates an insertion event and an extraction event of an electronic device, in accordance with the described embodiments. The hinge feature may include an elastomeric material designed to allow a region of the accessory device to pivot or bend with respect to another region of the accessory device. However, in other embodiments, the hinge feature is formed from metal or plastic. 
     In step  1102 , a first region of the unibody accessory device is secured with the hinge feature. In step  1104 , a second region of the unibody accessory device with the hinge feature. The first region and the second region may combine to define a receptacle region designed to carry the electronic device. Also, the hinge feature allows the first region to pivot at the hinge feature and bend with respect to the second region. 
     In step  1106 , a sidewall along the first region and the second region is formed. The sidewall may include one or more materials selected from a rigid thermoplastic, a material defining the hinge feature, and a silicone layer over molded to the rigid thermoplastic. In some embodiments, a force applied to the first region pivots the first region at the hinge feature and bends the sidewall at the hinge feature to allow the insertion event or the extraction event.
