[0024] Those skilled in the art will recognize and appreciate that, according to common practice, the various features of the figures described below are not necessarily drawn to scale, and that the dimensions of various features and elements of the figures may be expanded or reduced to more clearly show the embodiments of the present invention described herein. DETAILED DESCRIPTION OF THE INVENTION

[0025] Reference will now be made in detail to exemplary embodiments as illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit these embodiments to a single preferred embodiment. On the contrary, the following description is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the described embodiments as defined by the appended claims.

[0026] In the following Detailed Description, reference is made to the accompanying drawings, which form a part of the description, and in which is shown by way of illustration specific embodiments in accordance with the described embodiments. These embodiments are described in sufficient detail to enable those skilled in the art to practice the described embodiments, but it will be understood that these examples are not limiting, and that other embodiments may be used and changes may be made without departing from the spirit or scope of the described embodiments.

[0027] The following disclosure relates to accessory devices suitable for use with electronic devices such as mobile wireless communication devices (e.g., smartphones and tablet computing devices). In addition to providing a protective cover, the accessory devices described herein can support and orient the electronic device and allow a user to access the electronic device. The accessory devices described herein may include multiple parts, such as a first part (or cover part) and a second part (or keyboard / input part) pivotally coupled by one or more hinge assemblies. The first part includes several segments, at least some of which include magnets designed to magnetically couple with magnets in the electronic device. The second part includes an input mechanism (e.g., keyboard, trackpad) that allows a user to interact with the electronic device. Unlike conventional accessory devices, the accessory devices described herein can hold / suspend the electronic device, allowing the electronic device to "float" or hover. For example, using the hinge assembly, the segments of the first portion can hold and suspend the electronic device above the second portion without the electronic device touching the second portion, thereby allowing a user to view the electronic device and interact with the input mechanism to control the electronic device.

[0028] The hinge assembly provides sufficient friction to allow the first portion to remain in a fixed position while holding and suspending the electronic device against gravity. This feature of the accessory device offers several advantages. For example, the keyboard and electronic device remain sufficiently spaced apart, allowing for greater flexibility in the design / layout of the electronic device relative to the keyboard, or the keyboard relative to the electronic device. Furthermore, based on the "floating" nature of the electronic device, the accessory device can position the electronic device at least partially above the keyboard, while still allowing the user to interact with keys positioned below the electronic device. Furthermore, to prevent excessive rotation and tilting of the electronic device, the hinge assembly can incorporate an integrated stop mechanism that limits the movement of the portion, and therefore the electronic device.

[0029] The hinge assemblies of the accessory devices described herein can provide additional functionality. For example, in addition to limiting movement of the segments and providing friction that allows the segments to hold the electronic device in a fixed position (against gravity), some hinge assemblies can provide a path for wiring to be guided through the multiple segments. In this regard, the accessory devices described herein may include electrical contacts designed to establish communication between the electronic device and the accessory device. Additionally, the accessory devices described herein may include a port that accepts a connector from an external power source. Using the electrical contacts, the accessory devices described herein can relay electrical energy from the external power source to the electronic device to charge the electronic device's battery(ies).

[0030] These and other embodiments are described below with reference to Figures 1 through 16. However, those skilled in the art will readily appreciate that the detailed description provided herein with respect to these figures is for illustrative purposes only and should not be construed as limiting.

[0031] FIG. 1 is an isometric view of an electronic device 100 according to some described embodiments. Accessory device 100 may be referred to as a cover, protective cover, or folio, by way of non-limiting example. As shown, accessory device 100 includes portion 102a and portion 102b. Portion 102b is designed to move (i.e., rotate) relative to portion 102a, and vice versa. Portions 102a and 102b may be referred to as a first portion and a second portion, respectively. However, "first" and "second" may be used interchangeably. Furthermore, portions 102a and 102b may be referred to as a keyboard portion and a cover portion, respectively. Portion 102a may include input mechanism 104a and input mechanism 104b. As shown, input mechanism 104a includes a keyboard, and input mechanism 104b includes a trackpad or touchpad.

[0032] Portion 102b may include multiple segments. For example, portion 102b includes segment 106a and segment 106b. Segment 106a is designed to move (i.e., rotate) relative to segment 106b, and vice versa. Segments 106a and 106b may be referred to as a first segment and a second segment, respectively. However, "first" and "second" may be used interchangeably.

[0033] Portion 102b may include several magnets embedded within segments 106a and 106b. For example, portion 102b includes magnets 108a, 108b, 108c, 108d, and 108e located within segment 106a. Furthermore, portion 102b includes magnets 108f, 108g, and 108h located within segment 106b. Additionally, portion 102a includes magnets 108i and 108j. Note that each of these magnets is represented by a rectangular perimeter. However, in some examples, the rectangular perimeter represents several separate magnetic elements. At least some of these magnets are designed to magnetically couple with magnets within the electronic device (not shown in FIG. 1 ). In this manner, accessory device 100 can hold / secure the electronic device to portion 102b. Additionally, the magnets located within segment 106a may provide a magnetic field sufficient to hold / secure the electronic device and suspend it above portion 102a, even taking into account the weight of the electronic device and the effects of gravity. At least some of the magnets may also provide a magnetic field that can be detected by a sensor in the electronic device, which detection may be used as logic to determine the relationship between accessory device 100 and the electronic device, as will be further described below.

[0034] Portion 102b may also include an opening 109, or through-hole, formed in segment 106a. In this manner, an electronic device including a camera assembly and / or a flash module is not covered by portion 102b when the electronic device is secured to portion 102b. Although opening 109 is shown in a particular location on segment 106a, opening 109 may be located anywhere on segment 106a depending on the location of the camera assembly and flash module on the electronic device.

[0035] Accessory device 100 may further include electrical contacts 110 located on segment 106a. In this regard, when an electronic device is secured to portion 102b, accessory device 100 may form a communication channel with the electronic device using electrical contacts 110. As a result, a user may use input mechanism 104a to provide input or commands to the electronic device in the form of keystrokes, and a user may use input mechanism 104b to provide input to the electronic device in the form of gestures on input mechanism 104b and / or depressions (i.e., clicks) of input mechanism 104b. While electrical contacts 110 are shown in specific locations on segment 106a, electrical contacts 110 may be located anywhere on segment 106a depending on the location of the electrical contacts on the electronic device. Also, while electrical contacts 110 are shown as three electrical contacts, electrical contacts 110 may differ in other embodiments. Notably, electrical contacts 110 may include multiple contacts depending on the number of electrical contacts located on the electronic device.

[0036] Accessory device 100 may further include port 112. Port 112 may include a cavity or recess designed to receive a cable connector (not shown in FIG. 1 ) connected to an external power source. Port 112 may be designed for an industry standard, such as, by way of non-limiting example, Universal Serial Bus (“USB”) or USB-C. However, other industry standards are possible. Port 112 also electrically communicates with electrical contacts 110 via a cable or flexible circuit (not shown in FIG. 1 ). As a result, accessory device 100 can receive electrical energy via port 112 and can provide electrical energy to an electronic device in electrical communication with electrical contacts 110. The electrical energy can be used to charge the battery(ies) of the electronic device. Also, while port 112 is described as a means for supplying energy to the electronic device, in some embodiments, port 112 is also used for bidirectional data transmission between the electronic device and an external data source (not shown in FIG. 1 ), such as a computing device or a data server. Thus, in some embodiments, port 112 is used for bidirectional data transmission between accessory device 100 and the aforementioned external data source. Furthermore, it should be noted that accessory device 100 provides direct current ("DC") through electrical contacts 110. In this regard, accessory device 100 does not provide relatively high voltages or relatively large currents through electrical contacts 110, and therefore electrical contacts 110 are safe for human contact.

[0037] To facilitate relative rotational movement between portions 102a and 102b, accessory device 100 may include multiple cylindrical members. For example, accessory device 100 includes cylindrical member 114a coupled to portion 102a and cylindrical member 114b coupled to portion 102b. Each of cylindrical members 114a and 114b may define a generally hollow tube or shaft, thereby providing a conduit for other components. In this regard, accessory device 100 may integrate a hinge assembly (including a clutch mechanism and a spring mechanism) within cylindrical members 114a and 114b, as further shown and described below.

[0038] Cylindrical members 114a and 114b may comprise a metal, such as aluminum (including anodized aluminum), as a non-limiting example. Thus, cylindrical members 114a and 114b can provide a rigid component to protect accessory device 100 if accessory device 100 is dropped and absorbs significant force. However, accessory device 100 may also include non-metallic components 116a and 116b to protect the electronic device from damage through contact with cylindrical members 114a and 114b when accessory device 100 is dropped while being carried. Non-metallic components 116a and 116b can prevent metal-to-metal contact between the electronic device housing and cylindrical members 114a and 114b. Furthermore, non-metallic components 116a and 116b can be used as shock absorbers. Non-metallic parts 116a and 116b may be constructed from material(s) including, by way of non-limiting example, rubber, plastic(s), and / or fabric(s).

[0039] To cover and shield certain internal features and components, accessory device 100 may include multiple covers. For example, accessory device 100 includes cover 118a located on portion 102a and cover 118b located on portion 102b (such that cover 118b overlies segments 106a and 106b). Covers 118a and 118b generally cover one area of ​​accessory device 100 (e.g., the front area). In this regard, accessory device 100 may further include cover 118c generally covering another area of ​​accessory device 100 (e.g., the back area). In some embodiments, the covers include silicone and / or fabric. In the embodiment shown in FIG. 1, the covers include polypropylene terephthalate ("PTP") and thermoplastic polyurethane ("TPU") laminated together. The TPU layer can provide a structurally rigid layer, while the PTP layer provides an aesthetic exterior finish.

[0040] Although the aforementioned covers substantially cover areas of accessory device 100, these covers may include openings to accommodate particular features. For example, cover 118a includes an opening for the keys of input mechanism 104a as well as an opening for input mechanism 104b. With respect to the former, the opening in cover 118a may define a web through which the keys of input mechanism 104a pass. Furthermore, both input mechanisms 104a and 104b may be flush with or below cover 118a. Furthermore, covers 118b and 118c generally do not cover opening 109.

[0041] Accessory device 100 may further include weights 120a and 120b. When an electronic device is secured to accessory device 100, for example, at segment 106a, the center of mass of the system (i.e., accessory device 100 plus electronic device) may make the system vulnerable to tipping or dropping. Furthermore, forces imparted by a user's interaction with the electronic device may also cause accessory device 100 to tip or drop. However, weights 120a and 120b are designed to counteract those effects caused by accessory device 100 carrying the electronic device. This is shown further below.

[0042] 2 is an isometric view of accessory device 100 shown in FIG. 1 , illustrating an electronic device 200 that can be used with accessory device 100. Electronic device 200 may include a portable electronic device such as a mobile wireless communication device (e.g., a smartphone, a tablet computing device). Electronic device 200 may include an enclosure 202, or housing, designed to carry and electrically couple several components (not shown), such as, by way of non-limiting example, processing circuitry (e.g., a central processing unit, a graphics processing unit, an application-specific integrated circuit), a memory circuit, a battery, an audio speaker, a microphone, and a flexible circuit. Electronic device 200 may further include a display assembly 204 coupled to enclosure 202. Display assembly 204 may include a touch input display.

[0043] Electronic device 200 may further include magnets designed to magnetically couple with magnets in accessory device 100. For example, electronic device 200 includes magnets 208a, 208b, 208c, 208d, and 208e located in segment 106a, which are designed to magnetically couple with magnets 108a, 108b, 108c, 108d, and 108e, respectively. Additionally, electronic device 200 includes magnets 208f and 208g located in segment 106b, which are designed to magnetically couple with magnets 108f and 108g, respectively. Electronic device 200 further includes magnet 208i designed to magnetically couple with magnet 108i located in portion 102a. In the state of accessory device 100 shown in FIG. 2 , magnets 208f, 208g, and 208i are not magnetically coupled to magnets 108f, 108g, and 108i, respectively. However, in other states (shown and described below), magnets 208f, 208g, and 208i are magnetically coupled with magnets 108f, 108g, and 108i, respectively. Also, like the magnets of accessory device 100, the magnets of electronic device 200 are represented by a rectangular perimeter that may represent several separate magnetic elements or a single magnetic element.

[0044] Electronic device 200 further includes electrical contacts 210 designed to be electrically coupled to electrical contacts 110 of accessory device 100, thereby enabling electronic device 200 to communicate with accessory device 100. Electronic device 200 also includes sensors 220a and 220b. In some embodiments, sensors 220a and 220b each include a magnetic field sensor, such as a Hall Effect sensor (as a non-limiting example). Sensors 220a and 220b are designed to detect at least some of the magnets located within accessory device 100. For example, magnet 108h is positioned such that sensor 220a can detect the magnetic field generated by magnet 108h, and magnet 108j is positioned such that sensor 220b can detect the magnetic field generated by magnet 108j. In the state of accessory device 100 shown in FIG. 2 , the magnetic fields generated by magnets 108h and 108j cannot be detected by sensors 220a and 220b, respectively. However, under other conditions (shown and described below), the respective magnetic fields generated by magnets 108h and 108j can be detected by sensors 220a and 220b, respectively.

[0045] Electronic device 200 may include a camera assembly 222 and a flash module 224. Opening 109 in accessory device 100 is sized and positioned such that camera assembly 222 and flash module 224 are not obstructed by segment 106a.

[0046] FIG. 3 is a plan view of accessory device 100 shown in FIG. 1 , illustrating various components of portion 102b. For illustrative purposes, cover 118b (shown in FIG. 1 ) has been removed. Multiple hinges are coupled to segments 106a and 106b of portion 102b. For example, as shown in the enlarged view, portion 102b includes hinge 126a and hinge 126b. Hinges 126a and 126b allow some relative pivotal movement of segments 106a and 106b, while hinges 126a and 126b can also limit or control the movement of segment 106a relative to segment 106b. For example, segment 106a can be pivoted relative to segment 106b up to a predetermined angle based on the configuration and structure of hinges 126a and 126b. Thus, each of hinges 126a and 126b may be referred to as a stop hinge.

[0047] Portion 102b further includes hinges 128a and 128b. Hinges 128a and 128b may include several friction elements (shown but not labeled) that frictionally engage with one another. In this manner, the frictional force provided by hinges 128a and 128b can maintain an initial fixed position of segment 106a relative to segment 106b. However, if a rotational force that overcomes the frictional force provided by hinges 128a and 128b is applied to segment 106a, segment 106a can rotate relative to segment 106b unless the predetermined angle between segments 106a and 106b is achieved based on hinges 126a and 126b. Furthermore, when the applied force falls below the frictional force provided by hinges 128a and 128b, segment 106a remains in its subsequent fixed position relative to segment 106b. Accordingly, each of hinges 128a and 128b may be referred to as a friction hinge. Further details regarding hinges 128a and 128b and their respective friction elements may be found, for example, in U.S. patent application Ser. No. 16 / 041,633, entitled "HINGE ASSEMBLY WITH LAYERED FRICTION ELEMENTS," which is incorporated herein by reference in its entirety. Additionally, the functions and features of hinges 126a and 126b, as well as hinges 128a and 128b, are further shown and described below.

[0048] Portion 102b further includes hinges 130a and 130b. In addition to facilitating pivotal movement between segments 106a and 106b, hinges 130a and 130b also define conduits for wiring. As shown, wires 132a and 132b (each representing one or more wires) pass through hinges 130a and 130b, respectively, including through the barrels of hinges 130a and 130a, respectively. Wires 132a and 132b are used to electrically couple electrical contacts 110 to port 112. Additionally, wires 132a and 132b can also be used to electrically couple electrical contacts 110 to input mechanisms 104a and 104b (both shown in FIG. 1). Portion 102b further includes hinge 133a and hinge 133b, which may assist / facilitate the pivoting of segment 106a relative to segment 106b, respectively.

[0049] To pivotally couple portion 102a with portion 102b, accessory device 100 further includes hinge assemblies. For example, accessory device 100 includes hinge assemblies 134a and 134b. Hinge assemblies 134a and 134b are connected to cylindrical members 114a and 114b, respectively. Further details of hinge assemblies 134a and 134b are provided below.

[0050] FIG. 4 is an exploded view of hinge assembly 134a shown in FIG. 3. As shown, hinge assembly 134a includes clutch mechanism 136 and spring mechanism 138. Clutch mechanism 136, or simply clutch, includes shaft 142a designed to engage cylindrical member 114b (shown in FIG. 3). Clutch mechanism 136 further includes pivot mechanism 144 coupled to shaft 142a. As shown in the enlarged view, pivot mechanism 144 engages component 148, specifically, surface 150a of 148. In response to rotation of portion 102b relative to portion 102a (both portions shown in FIG. 1), pivot mechanism 144 (together with shaft 142a) can pivot relative to 148 in the direction indicated by arrow 149. Pivot mechanism 144 can continue to pivot until surface 152 of pivot mechanism 144 engages surface 150b of component 148. When surfaces 152 and 150b engage one another, further rotation of pivot mechanism 144 is prevented, and further rotational movement of portion 102b relative to portion 102a is also prevented. However, pivot mechanism 144 can be rotated in the opposite direction (i.e., the direction opposite arrow 149) until pivot mechanism 144 again engages surface 150a, thereby preventing rotation of portion 102b relative to portion 102a in the opposite direction. Thus, clutch mechanism 136 can provide a stop mechanism for limiting movement of portion 102b relative to portion 102a in two different directions, as will be further described below.

[0051] Clutch mechanism 136 further includes a friction mechanism 146 that frictionally engages shaft 142a. Even when pivot mechanism 144 is not engaged with either surface 150a or 150b of component 148, the frictional engagement of friction mechanism 146 with shaft 142a can provide sufficient frictional force to maintain a fixed position between portions 102a and 102b. Thus, clutch mechanism 136 provides frictional force to maintain portion 102b in a fixed position relative to portion 102a, such as the position shown in FIG. 1 . Additionally, clutch mechanism 136 may include several detents located on the outer periphery of component 148. For example, clutch mechanism 136 includes detents 154a and 154b (each representing an additional detent) located on the outer surface of portion 148. Detents 154a and 154b can provide a user with an indication of the rotational movement while the user rotates portion 102b relative to portion 102a, particularly when accessory device 100 (shown in FIG. 1) transitions from a closed state to an open state, or vice versa. The open and closed states are shown and described below.

[0052] Clutch mechanism 136 further includes shaft 142b. In some embodiments, shafts 142a and 142b define a unitary (i.e., single-piece or monolithic) shaft. Thus, in these embodiments, shafts 142a and 142b represent opposite ends of a single shaft. In other embodiments, shafts 142a and 142b are separate bodies.

[0053] The spring mechanism 138 is designed to counterbalance the weight of the electronic device 200 (shown in FIG. 2) when the electronic device 200 is magnetically coupled to the portion 102b. In this regard, the spring mechanism 138 can prevent the portion 102b from rotating and collapsing due to the weight of the electronic device 200. Therefore, the spring constant of the spring mechanism 138 can be selected based on the weight of the electronic device 200 and the portion 102b. For coupling to the clutch mechanism 136, the spring mechanism 138 includes an opening 156 that receives the shaft 142b. The spring mechanism 138 further includes a spring end 158 designed to be coupled to the cylindrical member 114a (shown in FIG. 3).

[0054] As an example, rotation of portion 102b (both portions shown in FIG. 1) relative to portion 102a causes rotation of shaft 142a. The rotation of shaft 142a causes corresponding rotation of pivoting mechanism 144. The rotation of pivoting mechanism 144 causes corresponding rotation of shaft 142b, which provides a rotational force to spring mechanism 138. The rotation of the components may continue until pivoting mechanism 144 engages a surface of part 148 (i.e., surface 150a or surface 150b). Additionally, friction mechanism 146 provides frictional engagement with (at least) shaft 142a, so that portion 102b can remain in a fixed position relative to portion 102a once rotation stops. Hinge assembly 134b (shown in FIG. 3) may include any of the components and features shown and described for hinge assembly 134a.

[0055] 5 is an isometric view of cylindrical members 114a and 114b. As shown, cylindrical member 114a includes an opening 158a in a rounded or curved surface of cylindrical member 114a. Additionally, cylindrical member 114a includes a diameter 160a, and cylindrical member 114b includes a diameter 160b that is smaller than diameter 160a. Based on opening 158a of cylindrical member 114a and the respective diameters of cylindrical members 114a and 114b, cylindrical member 114a can be fitted into cylindrical member 114b. Additionally, cylindrical members 114a and 114b may be referred to as an outer cylindrical member and an inner cylindrical member, respectively, based on their respective positional relationship.

[0056] Cylindrical member 114a, along with cylindrical member 114b, may include additional openings. For example, cylindrical member 114a includes opening 158b, and cylindrical member 114b includes opening 162a. Openings 162a and 158b allow wiring, such as wires 132a and 132b (shown in FIG. 3), to pass through cylindrical members 114b and 114a, respectively. Cylindrical members 114a and 114b include openings 158c and 162b, respectively, designed to receive a portion of hinge assembly 134a (shown in FIG. 3). Cylindrical members 114a and 114b also include openings 158d and 162c, respectively, designed to receive a portion of hinge assembly 134b (shown in FIG. 3).

[0057] As shown, cylindrical members 114a and 114b are connected to plates 164a (partially shown) and 164b, respectively. Plates 164a and 164b may be connected to portions 102a and 102b (both shown in FIG. 1), respectively. When cylindrical members 114a and 114b are assembled to hinge assemblies 134a and 134b (shown in FIG. 3), cylindrical members 114a and 114b may define hinge assemblies for pivoting portion 102b relative to portion 102a.

[0058] FIG. 6 is a cross-sectional view of the cylindrical member 114a shown in FIG. 5 taken along line 6-6. As shown, the cylindrical member 114a includes a lobe 166a, a lobe 166b, and a lobe 166c. Each of the lobes 166a, 166b, and 166c defines an undercut in the cylindrical member 114a. The cylindrical member 114a is designed to fit a spring mechanism (similar to the spring mechanism 138 shown in FIG. 3) into an opening 168 partially defined by the lobes 166a, 166b, and 166c. Additionally, the cylindrical member 114a can receive a fitting 170 designed to couple to the spring mechanism. The fitting 170 includes a recess 172 that receives a spring end (similar to the spring end 158 shown in FIG. 3).

[0059] Component 170 can be used to rotate, and thus bias, the spring mechanism to move further into opening 168 of cylindrical member 114a. For example, FIG. 7 is a cross-sectional view of cylindrical member 114a shown in FIG. 5 taken along line 7-7. FIG. 7 depicts a different position of opening 168 compared to the position of opening 168 shown in FIG. 6. For example, the position of opening 168 shown in FIG. 7 includes lobes 172a, 172b, and 172c, which are similar to lobes 166a, 166b, and 166c, respectively (shown in FIG. 6). However, lobes 172a, 172b, and 172c are offset at a predetermined angle relative to lobes 166a, 166b, and 166c, respectively. As the spring mechanism is rotated, it is moved by part 170 into opening 168 where the spring member is surrounded by, and in some cases positioned against, lobes 172a, 172b, and 172c.

[0060] 8-13 show and describe various states of the accessory device 100 and the relationships associated with the electronic device 200 based on the state of the accessory device 100. FIG.

[0061] 8 is a side view of accessory device 100 and electronic device 200, showing accessory device 100 in a closed state. As shown, accessory device 100 is wrapped around electronic device 200, thereby covering multiple surfaces of electronic device 200. Additionally, accessory device 100 is coupled to electronic device 200 by magnets. For example, magnets 108a, 108b, 108f, and 108i of accessory device 100 are magnetically coupled to magnets 208a, 208b, 208f, and 208i of electronic device 200, respectively. Although not shown, additional magnetic couplings may be present.

[0062] Also, in the closed state, sensors 220a and 220b can detect magnetic fields from magnets 108h and 108j, respectively, and provide signals based on the detection of the magnetic fields. Electronic device 200 can determine that accessory device 100 is in the closed state based on input signals received by sensors 220a and 220b indicating the detection of the respective magnetic fields from magnets 108h and 108j, respectively. Thus, electronic device 200 can determine that display assembly 204 is covered by accessory device 100 and can place display assembly 204 in a hibernation state. In the hibernation state, display assembly 204 is off.

[0063] 9 shows a side view of accessory device 100 and electronic device 200 in a different orientation, showing accessory device 100 in a closed position. Based on the orientation of accessory device 100 and electronic device 200, gravity is in the direction of arrow 174. If the system (defined by accessory device 100 and electronic device 200) is dropped, non-metallic component 116a is positioned between electronic device 200 and cylindrical member 114a. As a result, non-metallic component 116a prevents collision between electronic device 200 and cylindrical member 114a, thereby preventing damage to electronic device 200. Non-metallic component 116b (shown in FIG. 1) is positioned in a similar manner to that described for non-metallic component 116a and therefore provides similar benefits.

[0064] 10 is a side view of accessory device 100 and electronic device 200, showing accessory device 100 in a partially open state. In the partially open state, portion 102b is pivoted away from portion 102a by angle α. Because hinge assemblies 134a and 134b (shown in FIG. 3) limit further pivotal movement of portion 102b away from portion 102a, angle α may represent the maximum angle between portions 102b and 102a. In particular, the relationship between pivot mechanism 144 and component 148 (shown in FIG. 3) can stipulate / define angle α.

[0065] FIG. 11 is an isometric view of accessory device 100 and electronic device 200, showing accessory device 100 in a partially open state and display assembly 204 of electronic device 200 in a resting state. When accessory device 100 transitions from a closed state (shown in FIGS. 8 and 9 ) to a partially open state (shown in FIG. 11 ), display assembly 204 remains in the resting state. In this regard, referring back to FIG. 10 , in the partially open state, sensor 220b no longer detects the magnetic field from magnet 108j. However, sensor 220a can still detect the magnetic field from magnet 108h. As a result, display assembly 204 is in an inactive state, as sensor 220a provides input based on detecting the magnetic field from magnet 108h.

[0066] FIG. 12 is a side view of accessory device 100 and electronic device 200, showing accessory device 100 in an open position. As shown, segment 106a is rotated from its original position in a partially open position (shown in FIG. 10) to an angle β in an open position. Because hinges 126a and 126b (shown in FIG. 3) limit further rotational movement of segment 106a, angle β may represent the maximum angle of rotation by segment 106a. Thus, the design and configuration of hinges 126a and 126b can stipulate / define angle β. Furthermore, based on the frictional force provided by hinges 128a and 128b (shown in FIG. 3), segment 106a can remain in a fixed position, i.e., at angle β. Based on the frictional force provided by hinges 128a and 128b, segment 106a can be further rotated relative to segment 106b by an angle somewhat smaller than angle β and can remain in a fixed position at that angle (smaller than angle β).

[0067] Generally, accessory device 100 is designed so that portion 102b is rotated to angle α prior to rotation of segment 106a. This is based in part on the frictional forces provided by hinges 128a and 128b and hinge assemblies 134a and 134b (all shown in FIG. 3). Additionally, in the partially open state (shown in FIGS. 10 and 11), magnet 108f in accessory device 100 remains magnetically coupled with magnet 208f in electronic device 200. This resulting magnetic attraction maintains electronic device 200 relative to segments 106a and 106b, thereby preventing rotation of segment 106a. However, as shown in FIG. 12, when portion 102a moves away from portion 102b by angle α, the additional rotational force applied to segment 106a can overcome the magnetic attraction between magnets 108f and 208f, resulting in segment 106a rotating and moving electronic device 200 away from segment 106b.

[0068] Furthermore, when portion 102b (particularly, segment 106b shown in FIG. 12 ) moves away from portion 102a by angle α and segment 106a rotates to angle β, electronic device 200 moves away from portion 102a by angle γ. Angle γ is the sum of angles α and β and represents the maximum angle between portion 102b and portion 102a (particularly, segment 106a and portion 102a). In other words, angle γ represents the maximum angle between electronic device 200 and portion 102a. Angle γ may be in the range of approximately 110 degrees to 150 degrees. In some embodiments, angle γ is 135 degrees. Furthermore, angle β may be in the range of approximately 40 degrees to 80 degrees, and angle γ may be in the range of approximately 30 degrees to 70 degrees, as long as the sum of angles α and β is within the predetermined angle range for angle α.

[0069] Also, in the open state, electronic device 200 is no longer engaged with segment 106b. In other words, electronic device 200 is only engaged with segment 106a in the open state. Although magnet 108f in accessory device 100 is no longer magnetically coupled with magnet 208f in electronic device 200, the magnetic coupling between some magnets in accessory device 100 (i.e., the magnets in segment 106a) and the magnets in electronic device 200 can provide sufficient magnetic force to hold electronic device 200 relative to segment 106a. Furthermore, the magnetic coupling between the magnets in accessory device 100 and electronic device 200 provides sufficient magnetic force to suspend electronic device 200 above portion 102a so that electronic device 200 does not come into contact with portion 102a, as shown in FIG. 12 .

[0070] Also, as shown in the close-up view, cover 118c is at least partially disengaged from segments 106a and 106b. At this point, cover 118c is no longer bonded (e.g., by adhesive) to segments 106a and 106b. As a result, when accessory device 100 is in the open position, cover 118c is free to move at least partially away from segments 106a and 106b to avoid undesired buckling and to avoid undesired reaction forces from cover 118c that would otherwise interfere with the hinges (shown in FIG. 3).

[0071] 13 is an isometric view of accessory device 100 and electronic device 200, showing accessory device 100 in an open state and display assembly 204 of electronic device 200 in an activated state. In the open state, sensors 220a and 220b no longer detect the magnetic fields from magnets 108h and 108j, respectively. As a result, input from sensors 220a and 220b indicating the absence of a detected magnetic field (or lack thereof) can be used to activate display assembly 204, i.e., turn on display assembly 204, as shown in FIG.

[0072] Thus, when accessory device 100 transitions from the partially open state (shown in FIGS. 10 and 11 ) to the open state (shown in FIG. 13 ), electronic device 200 activates display assembly 204. Furthermore, display assembly 204 can remain activated when accessory device 100 transitions from the open state back to the partially open state. However, when accessory device 100 transitions from the partially open state to the closed state (shown in FIGS. 8 and 9 ), sensors 220 a and 220 b detect magnets 108 h and 108 j, respectively, and electronic device 200 can deactivate display assembly 204 and provide input to electronic device 200 indicative of the detection of a magnetic field. Additionally, weights 120 a and 120 b located on portion 102 a of accessory device 100 can prevent the system (i.e., accessory device 100 plus electronic device 200) from tipping due to the weight and position of electronic device 200 and / or due to a user's interaction with display assembly 204.

[0073] FIG. 14 is an isometric view of accessory device 100 with cover 118a removed from portion 102a to reveal additional features. As shown, accessory device 100 includes circuit board 176. Several components, such as processing circuitry and memory circuitry, may be located on circuit board 176. Additionally, circuit board 176 may be electrically coupled to input mechanisms 104a and 104b, for example, by connectors and / or flexible circuits (not shown in FIG. 14). Circuit board 176 is also electrically coupled to electrical contacts 110 (shown in FIG. 1). Circuit board 176 is designed to communicate with the aforementioned components and with electronic devices (not shown in FIG. 14) coupled to accessory device 100.

[0074] To increase structural rigidity, portion 102a may include a substantial amount of metal, such as aluminum. For example, portion 102a includes metal portion 178a, metal portion 178b, and metal portion 178c. Input mechanism 104a may also be backed by a metal plate (not shown in FIG. 14 ). While this can increase overall structural rigidity (compared to the use of a non-metallic material), metal may interfere with or block radio frequency (“RF”) signals intended to be transmitted and / or received by electronic device 200 (not shown in FIG. 14 ). For example, in the closed state of accessory device 100 (shown in FIG. 8 ), portion 102a substantially covers one surface of electronic device 200, with the metal being located in close proximity to electronic device 200.

[0075] To modify accessory device 100 to enhance / allow RF transmission, portion 102a may include multiple non-metallic portions. For example, as shown in FIG. 14 , portion 102a includes non-metallic portion 182a and non-metallic portion 182b. Non-metallic portions 182a and 182b may be formed, by way of non-limiting example, from a rigid plastic that generally does not block or impede RF transmission. The locations of non-metallic portions 182a and 182b are selected based on the corresponding locations of RF transmitting components (e.g., antennas) on electronic device 200, particularly when accessory device 100 maintains electronic device 200 in the closed position (shown in FIG. 8 ).

[0076] Portion 102a may also include a light source 184 designed to transmit light toward input mechanism 104a. Light source 184 may include one or more light-emitting diodes ("LEDs"). If input mechanism 104a includes a keyboard with several keys, the keys may be illuminated based on the light provided by light source 184. A circuit board 176 is also electrically coupled to light source 184 for controlling light source 184. In this regard, circuit board 176 may include control circuitry for activating and deactivating light source 184.

[0077] FIG. 15 is an isometric view of input mechanism 104b showing additional features of input mechanism 104b. The underside / bottom of input mechanism 104b is shown. Input mechanism 104b includes plates 186 that cover each corner of input mechanism 104b in addition to a central location 188 of input mechanism 104b. Using plates 186, a user can press down on a user input surface (not shown in FIG. 15), i.e., the touch surface of input mechanism 104b, generally at any location and experience a "click" sensation based on the press. The integration of plates 186 can also provide input mechanism 104b with a relatively smaller size and reduced height, allowing input mechanism 104b to be positioned substantially flush with cover 118a (as shown in FIG. 1).
