[0027] Those skilled in the art will recognize and understand that, by convention, the various features of the drawings discussed below are not necessarily drawn to scale, and the dimensions of the various features and elements of the drawings may be enlarged or reduced to more clearly illustrate the embodiments of the invention described herein. Detailed Implementation Modes

[0028] Reference will now be made specifically to representative embodiments shown in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to one preferred embodiment. Instead, it is intended to cover alternative forms, modifications, and equivalents that may be included within the spirit and scope of the described embodiments as defined by the appended claims.

[0029] In the following detailed description, reference is made to the accompanying drawings that form a part of the specification, and specific embodiments in accordance with the described embodiments are illustrated in the drawings. Although these embodiments are described in sufficient detail to enable those skilled in the art to practice the described embodiments, it should be understood that these examples are not restrictive, and thus other embodiments may be used and changes may be made without departing from the spirit and scope of the described embodiments.

[0030] The following disclosure relates to an electronic device and an accessory device designed to be used with the electronic device. The electronic device described herein may include a portable computing device, such as a tablet computing device, a smart phone, and a laptop computing device. As a non-limiting example, the accessory device described herein may be referred to as a portable accessory device, an accessory case, an accessory cover, or a folio. The accessory device described herein may include a cover having sections that are foldable relative to each other, and a keyboard coupled to the cover in a manner that allows rotational movement between the cover and the keyboard. The cover may also include electrical contacts designed to engage electrical contacts of the electronic device and enable electrical communication between the electronic device and the accessory device.

[0031] The accessory device described herein may include a number of magnetic elements designed and positioned to be magnetically coupled not only to magnetic elements in the electronic device, but also to other magnetic elements within the accessory device. Additionally, the accessory device described herein may include magnetic elements that generate an external magnetic field sufficient to hold the electronic device, even when gravity acting on the electronic device would otherwise cause the electronic device to fall from the accessory device. Further, based on the positions of the various magnetic elements, the accessory device described herein may be configured in various ways, thereby providing additional flexibility and benefits to the user.

[0032] Some of the accessory devices described herein include multiple sections, some of which provide a foldable cover while others provide a keyboard (in some cases). Additionally, some of the accessory devices described herein include a channel for holding an edge of the electronic device. These accessory devices may include additional magnetic elements around the channel to be magnetically coupled to magnetic elements in the electronic device.

[0033] Reference will be made below to Figures 1 - 18These and other embodiments will be described. However, those skilled in the art will readily understand that the detailed description given herein with respect to these figures is for illustrative purposes only and should not be construed as limiting.

[0034] Figure 1 An isometric front view of an embodiment of an electronic device 100 in accordance with some of the described embodiments is shown. The electronic device 100 may be referred to as a portable electronic device. For example, in some embodiments, the electronic device 100 is a laptop computing device. In other embodiments, the electronic device 100 is a mobile wireless communication device, such as a smart phone. In Figure 1 the illustrated embodiment, the electronic device 100 is a tablet computing device designed for user interaction and wireless communication.

[0035] The electronic device 100 may include a housing 102, or enclosure, which is designed to provide an internal volume (not labeled) to store a number of components, including (by way of non-limiting example) a circuit board, processor circuitry, memory circuitry, a battery (or batteries), an audio module (such as a speaker), a microphone, a camera, a light emitter and receiver, and a flexible circuit that electrically connects at least some of the foregoing components to each other. The housing 102 may include a rear wall and a plurality of side walls that extend from and are joined to the rear wall to define the internal volume. By way of non-limiting example, the housing 102 may include a rigid material that includes a metal (such as aluminum or an alloy containing aluminum), ceramic, or hardened plastic.

[0036] The electronic device 100 may also include a display assembly 104 (illustrated as a dashed line). Although not shown, the display assembly 104 may include a plurality of layers, including a display layer designed to provide visual information. The display assembly 104 may also include a touch input layer designed to receive touch inputs and provide the location of the touch inputs. The touch input layer may include capacitive touch technology for forming an electrostatic field and using changes in the electrostatic field to locate touch inputs. The electronic device 100 may also include a transparent cover 106 positioned on the display assembly 104 and coupled to the housing 102. The transparent cover 106 may provide a protective cover for the display assembly 104 and the foregoing components stored in the internal volume. The transparent cover 106 may include a transparent material, such as glass, plastic, sapphire, etc. The electronic device 100 may also include a border 108 that extends around the perimeter of the transparent cover 106 and covers the edge of the display assembly 104. The border 108 may provide for hiding or obscuring the display assembly 104 and other components ( Figure 1An opaque barrier for the electrical connection between (not shown in the figure). The boundary 108 can be applied to the inner surface of the transparent cover 106, and thus, the boundary 108 faces the internal volume. However, in some cases (not shown), the boundary 108 can be applied to the outer surface. Additionally, the boundary 108 can include a uniform scale along the X-axis and the Y-axis. In this way, the boundary 108 can appear uniform along the two-dimensional plane, thereby providing an aesthetically pleasing and consistent surface finish for the electronic device 100.

[0037] Although the boundary 108 is opaque or at least substantially opaque, some portions of the boundary 108 can be removed to form an opening (or openings). Additionally, one or more openings in the boundary 108 can be filled with a material that provides a light-transmitting (or translucent) quality while also matching or at least substantially matching the appearance of the boundary 108 (in terms of color and / or reflectivity). For example, the boundary 108 can include an opening with a material 110 that fills the opening. The material 110 can include an ink material (as a non-limiting example), and the ink material includes an appearance that matches the appearance of the boundary 108. For example, if the boundary 108 appears black, the material 110 can also appear black while still allowing light to pass through. In this way, the electronic device 100 can include a visual system for user authentication and a light sensor for detecting the amount of light incident on the electronic device 100. These features will be shown below.

[0038] When the housing 102 is formed of metal, some portions of the housing 102 can undergo machining operations to remove the metal, and non-metal can fill the voids left in the housing 102 due to the machining operations. For example, the housing 102 can include a sidewall 114a having an opening or window that opens to the internal volume of the electronic device 100, and a non-metal material 116a that fills the opening. The non-metal material 116a can include plastic, resin, and / or adhesive. In this way, the electronic device 100 can include components positioned in the internal volume along the non-metal material 116a, such as an inductive charging unit and an antenna ( Figure 1 (not shown in the figure). The non-metal material 116a provides a minimum (if any) blockage to radio frequency communication to and from the antenna. Therefore, the non-metal material 116a can be referred to as a radio frequency window. Additionally, the non-metal material 116a provides a minimum (if any) blockage to the inductive current from the inductive charging unit. Therefore, the inductive charging unit can be used to charge an object or accessory (such as a digital stylus) that is used to provide a touch input to the display assembly 104. These features will be shown below.

[0039] The housing 102 can also include through holes or openings leading to the internal volume. For example, the sidewall 114b can include through holes 118a and 118b. The through holes 118a and 118b can be used to allow the passage of signals from an audio module ( Figure 1The acoustic energy generated (not shown in the figure) leaves the electronic device 100. Additionally, at least some of the through-holes 118a and 118b can be used to receive acoustic energy, thereby allowing one or more microphones (not shown in the figure) in the electronic device 100 to process the acoustic energy. Although a discrete number of through-holes are shown in the sidewall 114b, the number of through-holes can vary. The electronic device 100 can include a connector 120 in the through-holes of the sidewall 114b. The connector 120 can be electrically coupled to a central processing unit (not shown in the figure) on a circuit board in the internal volume and a battery (or batteries, not shown) in the internal volume. In this way, the electronic device 100 can receive and transmit data for the central processing unit and can also receive electrical energy for charging and recharging the battery (or batteries). The connector 120 can include a Universal Serial Bus (“USB port”) connector, including a connector with a USB-C protocol. However, the connector 120 can take the form of other standardized connectors. Figure 1 not shown in the figure Figure 1 not shown in the figure

[0040] Figure 1 Figure 1 not shown in the figure

[0041] Figure 2 is shown Figure 1 An isometric rear view of the electronic device 100 shown in the figure is presented, which shows additional feature parts of the electronic device 100. The housing 102 can include a wall 124 (also referred to as a bottom wall or a rear wall), and the wall 124 has several openings to allow additional feature parts. For example, the wall 124 can include openings filled with a non-metallic material 116b. As a non-limiting example, the non-metallic material 116b can include plastics, resins, and / or adhesives. In this way, the wall 124 can allow radio frequency to enter and leave the housing 102 through the non-metallic material 116b. The wall 124 can also include openings for a camera assembly 126, a flash module 128, and a microphone 129.

[0042] Figure 1 Figure 1any of the feature portions shown in). Further, the housing 102 may include a sidewall 114d having through-holes similar to through-hole 118a and through-hole 118b (shown in Figure 1 shown in). The through-holes in the sidewall 114d may be used for additional audio modules and microphones (as shown below).

[0043] In addition to the connector 120, other feature portions may also enable the electronic device 100 to communicate with external devices. For example, the electronic device 100 may include electrical contacts 123a, electrical contacts 123b, and electrical contacts 123c. These contacts may be referred to as device contacts. The electrical contacts 123a, electrical contacts 123b, and electrical contacts 123c may include metal contacts designed to be electrically coupled to accessory devices ( Figure 2 not shown in), such as a cover, a folio, and / or a keyboard cover accessory.

[0044] Figure 3 A plan view of the electronic device 100 is shown, which shows several internal components of the electronic device 100. For simplicity of illustration, the transparent cover 106 and the display assembly 104 are removed to show additional feature portions. Figure 3 Several additional feature portions may also not be included. As shown, the housing 102 may define an internal volume 130 that provides space for carrying the components of the electronic device 100. Although not shown, the internal volume 130 may provide space for a circuit board carrying several processor circuits, some of which may be used as a central processing unit, a graphics processing unit, and a memory circuit. As a non-limiting example, the internal volume 130 may also provide space for a battery module, a microphone, and a flexible circuit.

[0045] The electronic device 100 may include several audio modules in the internal volume 130 of the housing 102. For example, the electronic device 100 may include an audio module 134a and an audio module 136a. In some embodiments, the audio module 134a is designed to generate sound energy in the form of audible sound in the range of approximately 2,000 hertz - 20,000 hertz (“Hz”), but in some cases, this range may be higher than 20,000 Hz. In some embodiments, the audio module 136a is designed to generate sound energy in the form of audible sound in the range of approximately 20 Hz - 5,000 Hz. In this regard, the audio module 134a may be referred to as a high-frequency speaker, and the audio module 136a may be referred to as a bass speaker.

[0046] Although both the audio module 134a and the audio module 136a can be fixed to the wall 124 (including adhesive fixing), the audio module 136a can be fixed to the inner wall 138a extending from the wall 124. The inner wall 138a can be formed integrally with the wall 124. In other words, the housing 102 can be formed from a block of material that has undergone machining operations such that the wall 124 and the inner wall 138a are formed into a continuous structure. As Figure 3 shown, the inner wall 138a is positioned between the side walls of the housing 102. The electronic device 100 can also include additional audio modules, including the audio module 134b, the audio module 134c, and the audio module 134d, which include similar features as described for the audio module 134a. Additionally, the electronic device 100 can also include additional audio modules, including the audio module 136b, the audio module 136c, and the audio module 136d, which include similar features as described for the audio module 136a, where the audio module 136b, the audio module 136c, and the audio module 136d are respectively fixed to the inner wall 138b, the inner wall 138c, and the inner wall 138d. Additionally, although not shown, the side walls of the housing 102 can include a number of through holes or openings that allow the sound energy generated by at least some of the audio modules to leave the electronic device 100.

[0047] As is well known in the art for audio modules, the audio module 136a can include a permanent magnet ( Figure 2 not shown in the figure) and an electromagnet ( Figure 2 not shown in the figure). However, additional magnetic elements can be accommodated between the inner walls 138a that fix the audio module 136a. For example, the electronic device 100 can include a magnetic element 140a positioned between the inner walls 138a. The magnetic element 140a (shown as a dashed line) is covered by a cover that is part of the audio module 136a. However, the magnetic element 140a is separated (physically and functionally) from the magnets used in the audio module 136a. As a non-limiting example, the magnetic element 140a can be fixed to the wall 124 by an adhesive. Additionally, the magnetic elements shown and described in the electronic device 100 can be referred to as device magnets.

[0048] As shown in the first enlarged view 150a, the magnetic element 140a can include multiple rows of discrete magnetic elements. Additionally, the magnetic element 140a is arranged in a pattern where some of the magnetic elements include a north pole (or north-facing polarity) represented by a "+" facing away from the wall 124, while the remaining magnetic elements of the magnetic element 140a include a south pole (or south-facing polarity) represented by a "-" facing away from the wall 124. As shown in the figure, the magnetic element 140a includes a 3x6 matrix of magnetic elements. However, the number of magnetic elements can vary.

[0049] The electronic device 100 may include other magnetic elements 140b and magnetic elements 140c positioned between the inner walls 138b. Similar to the magnetic element 140a, the magnetic elements 140b and the magnetic elements 140c are covered by a cover that is part of the audio module 136b and are (physically and functionally) separate from the magnets used by the audio module 136b. As shown in the second enlarged view 150b, the magnetic element 140b may include multiple rows of discrete magnetic elements. In addition, the magnetic element 140b is arranged in a pattern in which some of the magnetic elements include a north pole facing away from the wall 124, while the remaining magnetic elements of the magnetic element 140b include a south pole facing away from the wall 124. As shown, the magnetic element 140b includes a 2x6 matrix of magnetic elements. However, the number of magnetic elements may vary. Additionally, the magnetic element 140c may include a single column of magnetic elements, some of which include a north pole facing away from the wall 124 and others of which include a south pole facing away from the wall 124.

[0050] The electronic device 100 may include other magnetic elements 140d positioned between the inner walls 138c. Similar to the magnetic element 140a, the magnetic element 140d is covered by a cover that is part of the audio module 136c and is (physically and functionally) separate from the magnets used by the audio module 136c. The electronic device 100 may include other magnetic elements 140e and magnetic elements 140f positioned between the inner walls 138d. Similar to the magnetic element 140b, the magnetic element 140e is covered by a cover that is part of the audio module 136d and is (physically and functionally) separate from the magnets used by the audio module 136d. Although not shown separately, the magnetic element 140d may include a 3x6 matrix of magnetic elements that may be arranged in a layout / arrangement similar to that of the magnetic element 140a. However, the layout / arrangement may be different. Additionally, although not shown separately, the magnetic element 140e and the magnetic element 140f may include a 2x6 matrix and a single column of magnetic elements, respectively. The layout / arrangement of the magnetic element 140e and the magnetic element 140f may be similar to the layout / arrangement of the magnetic element 140b and the magnetic element 140c, respectively. However, the layout / arrangement may be different.

[0051] The foregoing magnetic elements may be magnetically coupled to the magnetic elements in the various accessory devices described herein, thereby coupling the electronic device 100 to the accessory device. In addition, the magnetic coupling between the magnetic elements in the electronic device 100 and the accessory devices described herein provides a magnetic attraction force that allows the accessory device to hold and maintain the electronic device 100, even overcoming the gravitational force acting in the opposite direction of the magnetic attraction force.

[0052] When magnetically coupled to a magnetic element in an accessory device, the aforementioned magnetic element in the electronic device 100 can provide a large-scale adjustment of the electronic device 100 relative to the accessory device by, for example, providing a force that moves the electronic device 100 by approximately a few centimeters to align a corner of the electronic device 100 with a corner of the accessory device. Additionally, the electronic device 100 can include a magnetic element 140g and a magnetic element 140h that are designed and positioned to be magnetically coupled to a magnetic element of the accessory device. The magnetic coupling of the magnetic element 140g and the magnetic element 140h to the magnetic element in the accessory device can provide a small-scale adjustment of the electronic device 123 relative to the electrical contact of the accessory device. For example, a force is provided to move the electronic device 100 by approximately a few millimeters to align the electrical contact 123 with the electrical contact of the accessory device and ensure engagement, thereby enabling the electronic device 100 and the accessory device to communicate electrically.

[0053] Additionally, the aforementioned magnetic element can include a permanent magnet, such as neodymium. Furthermore, the coercivity of the aforementioned magnetic element can vary between discrete magnetic elements. For example, some magnetic elements can include a relatively high coercivity to increase a locally increased external magnetic field and provide additional magnetic attraction, while some magnetic elements can include a relatively low coercivity to locally reduce the total external magnetic field and prevent the external magnetic field from interacting with magnetically sensitive items (such as credit cards) placed outside the wall 124 of the electronic device 100.

[0054] The electronic device 100 can also include an inductive charging unit 142. The inductive charging unit 142 can include a ferrite coil that is designed to receive alternating current from an internal power source ( Figure 3 not shown), such as a battery module. The direct current (“DC”) provided by the battery module can pass through an inverter ( Figure 3 not shown) to generate alternating current. Thus, the inductive charging unit 142 can then provide an alternating electromagnetic field ( Figure 3 not shown) and act as a transmitter coil to power an object outside the electronic device 100 (e.g., a digital stylus positioned against the sidewall 114a). Figure 3Inductive charging (not shown in the figure) will be described below. A partial cross-section of the sidewall 114a is shown to illustrate the non-metallic material 116a. The inductive charging unit 142 is aligned with the non-metallic material 116a, and the electromagnetic field generated by the inductive charging unit 142 can pass through the non-metallic material 116a and induce a current in the object. The electronic device 100 may include magnetic elements 140i and 140j positioned along the sidewall 114a (including the non-metallic material 116a). The magnetic elements 140i and 140j are designed to be magnetically coupled to a magnet in the object, and the object can be positioned against the sidewall 114a and inductively charged by the inductive charging unit 142. Additionally, the magnetic elements 140i and 140j can be used to carry and store the object by magnetic attraction generally.

[0055] The electronic device 100 may include antennas 144a and 144b positioned along the non-metallic material 116a. The antennas 144a and 144b can enable wireless communication. Additionally, each antenna can provide radio frequency communication within a specific frequency range. For example, the antenna 144a can provide Wi-Fi communication, and the antenna 144b can provide communication. Other antennas ( Figure 3 (not shown in the figure) can enable cellular network communication.

[0056] The electronic device 100 may include magnetic elements 140k and 140l positioned along the sidewall 114c. The magnetic elements 140k and 140l are designed to be magnetically coupled to magnetic elements in an accessory device ( Figure 3 (not shown in the figure), such as a cover, folio, or keyboard cover accessory. Additionally, the magnetic elements 140k and 140l can position the electronic device 100 such that the sidewall 114c defines a base for the electronic device 100. This will be described below. The electronic device 100 may further include a magnetic element 140m designed to be magnetically coupled to a magnet of an accessory device ( Figure 3 (not shown in the figure) designed to cover the electronic device 100. Additionally, to assist in determining the user's orientation, the electronic device 100 may include a compass 146. The compass 146 may include a magnetometer designed to determine the Earth's magnetic field.

[0057] Figure 4 A plan view of the electronic device 100 is shown, which shows an object 150 positioned against the sidewall 114a. A partial cross-sectional view of the sidewall 114a shows the non-metallic material 116a. The object 150 may include a digital stylus that can interact with the display assembly 104, specifically, with the touch input layer of the display assembly 104 ( Figure 4 (not shown in the figure) and provide input thereto. In order for the object 150 to interact with the touch input layer, the object 150 needs a battery 152 to power the capacitive components and radio frequency components of the object 150Figure 4 A supply current (not shown in the figure) is provided, and both the capacitive component and the radio frequency component can be used to communicate with the electronic device 100. The battery 152 of the object 150 may include a rechargeable battery.

[0058] The inductive charging unit 142 of the electronic device 100 can charge the battery 152. The inductive charging unit 142 can act as a transmitter coil and inductively charge the battery 152 by inducing an alternating current (“AC”) to the receiver coil 154 of the object 150. The induced current can pass through an AC-to-DC converter (such as a rectifier), and can then be used to charge or recharge the battery 152. To induce current into the battery 152, the inductive charging unit 142 and the object 150 are positioned along the non-metallic material 116a. To hold the object 150 against the sidewall 114a (or against the non-metallic material 116a), the magnetic element 140i and the magnetic element 140j can be magnetically coupled to the magnetic element 305a and the magnetic element 305b in the object 150, respectively. Additionally, as shown in the figure, the antenna 144a and the antenna 144b are positioned along the non-metallic material 116a, allowing the antenna 144a and the antenna 144b to transmit and receive RF communications.

[0059] Figure 5 An isometric view of an embodiment of an accessory device 200 used with the electronic device 100 is shown according to some of the described embodiments. The accessory device 200 is designed to be a complementary device to the electronic device 100. As shown, the accessory device 200 may include a first section 202a and a second section 202b connected to the first section 202a. The accessory device 200 may include a hinge 204a that connects the first section 202a to the second section 202b. The hinge 204a allows the first section 202a to rotate or pivot relative to the second section 202b, and vice versa. The hinge 204a may include a flexible material (such as polyurethane, as a non-limiting example), which defines one or more outer layers extending across the first section 202a and the second section 202b.

[0060] The first section 202a, also referred to as a cover, cover portion, cover section, electronic device cover, or segmented cover, which may define a receiving surface for the electronic device 100, the size and shape of which are adapted to receive the rear surface of the housing 102 (defining the main surface of the housing 102). The first section 202a may include a first segment 206a and a second segment 206b, which together define the receiving surface. The first segment 206a is separated from the second segment 206b by a hinge 204b located between the first segment 206a and the second segment 206b. The hinge 204b allows rotational movement of the first segment 206a relative to the second segment 206b, and vice versa. The hinge 204b may be formed by one or more layers used to form the hinge 204a. In some embodiments (Figure 5 In (not shown), the first section 206a and the second section 206b generally have the same dimensions. In Figure 5 the illustrated embodiment, the first section 206a is larger than the second section 206b. Also, both the first section 206a and the second section 206b may include a microfiber layer (not labeled). In some cases, the microfiber layer is limited to the first section 206a and the second section 206b such that the microfiber layer does not cover the hinge 204b.

[0061] The second portion 202b, also referred to as the keyboard portion or the keyboard cover, may include a keyboard 208. As a non-limiting example, the keyboard 208 may include a number of keys (not labeled) arranged in a QWERTY configuration. The second portion 202b may also include one or more channels that are designed to provide a position that is lower than or nearly flush with the remaining position of the second portion 202b. For example, the second portion 202b may include a first channel 212a and a second channel 212b. The first channel 212a and the second channel 212b are designed to receive the electronic device 100 (or a portion of the electronic device 100) so as to place and position the electronic device 100 in a manner that enables the electronic device 100 to be used with the keyboard 208. Also, the second portion 202b may include a dimension 203a measured from the rear surface of the second portion 202b to the keys of the keyboard 208. The second portion 202b may include a dimension 203b measured from the rear surface of the second portion 202b to the portion surrounding the first channel 212a and the second channel 212b. The dimension 203a may be the same as or substantially similar to the dimension 203b such that the keys of the keyboard 208 are planar with respect to the portion surrounding the first channel 212a and the second channel 212b. In this way, when the electronic device 100 is coupled to the first portion 202a and the first portion 202a is folded over the second portion 202b, the electronic device 100 can be placed flat or horizontally on the second portion 202b.

[0062] The first section 202a may include an electrical contact 214 that is designed to engage an electrical contact 123 of the electronic device 100 and enable the accessory device 200 to communicate (including electrical communication) with the electronic device 100. The electrical contact 214 may be referred to as a device contact. When the accessory device 200 communicates with the electronic device 100, the keyboard 208 may be used to provide inputs and commands to the electronic device 100 to control the display assembly 104. As shown, the electrical contact 214 is positioned on the first segment 206a. However, other locations are possible (such as the second segment 206b). Generally speaking, the electrical contact 214 can be at any position corresponding to the position of the electrical contact 123 such that when the electronic device 100 contacts the first section 202a, the electronic device 100 is within the outer perimeter of the first section 202a. Moreover, although the electrical contact 214 represents physical / direct communication between the accessory device 200 and the electronic device 100, as a non-limiting example, the accessory device 200 and the electronic device 100 may also communicate via wireless communication (such as communication).

[0063] The first section 202a may also include an opening 216 or through-hole that is designed to receive the camera assembly 126 and the flash module 128 (shown as dashed lines). As shown, the opening 216 is located on the first segment 206a. However, other locations are possible. Generally speaking, the opening 216 can be at any position corresponding to the positions of the camera assembly 126 and the flash module 128 such that when the electronic device 100 contacts the first section 202a, the electronic device 100 is within the outer perimeter of the first section 202a.

[0064] Figure 6 Shown is Figure 5 a plan view of the accessory device 200 shown, which shows various internal components of the accessory device 200. For illustrative purposes, the keys of the keyboard 208 have been removed (shown in Figure 5 ). The first section 202a and the second section 202b may include a number of magnetic elements. Moreover, the magnetic elements located in the first section 202a may be referred to as cover magnetic elements or cover magnets since the first section 202a may be referred to as a cover or cover section. Also, the magnetic elements located in the second section 202b may be referred to as keyboard magnetic elements or keyboard magnets since the second section 202b may be referred to as a keyboard or keyboard section.

[0065] The first segment 206a of the first section 202a may include a number of magnetic elements that are designed to engage the electronic device 100 (in Figure 2The magnetic elements in (shown in) are magnetically coupled to hold the electronic device 100 against the first section 202a. For example, the first section 206a may include magnetic element 240a, magnetic element 240b, and magnetic element 240c. The magnetic elements for the accessory device 200 described herein may be represented by a rectangular structure. However, in terms of the number of rows and / or columns and the number of discrete magnetic elements, the magnetic elements include a layout / arrangement similar to that of the magnetic elements shown for the electronic device 100 in Figure 3 For example, magnetic element 240a may include a layout / arrangement similar to that of magnetic element 140a. However, the polarity of the discrete magnetic elements of magnetic element 240a may be reversed so as to form a number of magnetic paths (with north-south pairs of magnetic attraction) between magnetic element 240a and magnetic element 140a.

[0066] The first section 206a may further include magnetic element 240d, magnetic element 240e, and magnetic element 240f. At least some of magnetic element 240a, magnetic element 240b, and magnetic element 240c may be magnetically coupled to at least some of magnetic element 140a, magnetic element 140b, and magnetic element 140c (shown in Figure 3 ). In addition, at least some of magnetic element 240d, magnetic element 240e, and magnetic element 240f may be magnetically coupled to at least some of magnetic element 140d, magnetic element 140e, and magnetic element 140f (shown in Figure 3 ). These aforementioned magnetic couplings provide a magnetic attraction for large-scale alignment to align the corners of the electronic device 100 (shown in Figure 5 ) with the corners of the first section 202a. The first section 202a may further include magnetic element 240g and magnetic element 240h, which are capable of being magnetically coupled to magnetic element 140g and magnetic element 140h respectively (shown in Figure 3 ). This may provide small-scale alignment to align and engage the electrical contact 214 with the electrical contact 123 of the electronic device 100 (shown in Figure 3 ). The first section 202a may further include magnetic element 240i and magnetic element 240j, which are designed to be magnetically coupled to the magnets in the electronic device 100 (shown in Figure 3 ), such as magnetic element 140c and magnetic element 140f (shown in Figure 3 ).

[0067] The first section 202a and the second section 202b are designed to engage with each other and remain engaged through magnetic coupling. For example, the first section 202a may include magnetic elements 240k, magnetic elements 240l, magnetic elements 240m, and magnetic elements 240n, which are designed to be magnetically coupled to magnetic elements 242k, magnetic elements 242l, magnetic elements 242m, and magnetic elements 242n located in the second section 202b, respectively. For example, when the first section 202a is rotated such that the rear surface of the first section 202a ( Figure 6 (not shown in the figure)) engages the rear section of the second section 202b ( Figure 6 (not shown in the figure)), the aforementioned magnetic elements are magnetically coupled such that the rear surfaces remain engaged with each other. To further hold the rear surfaces to each other, the first section 202a may include magnetic elements 240o and magnetic elements 240p (located in the second segment 206b), which are designed to be magnetically coupled to magnetic elements 242o and magnetic elements 242p (located in the second segment 206b), respectively.

[0068] The magnetic elements in the first segment 206a (and in some cases, the first segment 206a and the second segment 206b) can hold the electronic device 100 (shown in Figure 5 ) against the first section 202a by magnetic attraction (collectively), even overcoming the gravity acting on the electronic device 100. In this regard, the first section 202a may not require mechanical retention features, such as sidewalls and / or latches, which are designed to surround and / or interlock with the electronic device 100 to hold the electronic device 100.

[0069] In some embodiments, the first segment 206a has the same size (or approximately the same size) as the second segment 206b. In the Figure 6 embodiment shown, the size of the first segment 206a is different from the size of the second segment 206b. This can help position the first section 202a in a desired manner to support the electronic device 100. This will be shown and described below.

[0070] The second section 202b may also include magnetic elements along the edge (of the second section 202b). For example, the second section 202b may include magnetic elements 242a, magnetic elements 242b, magnetic elements 242c, and magnetic elements 242d. These magnetic elements are designed to be magnetically coupled to magnetic elements (or magnetically attractable materials) in the electronic device 100 (shown in Figure 3 ) to hold the electronic device 100 against the second section 202b along the edge.

[0071] The second section 202b may include additional magnetic elements. For example, the second section 202b may include magnetic assemblies 244a and 244b (both shown as dashed lines), each magnetic assembly including two or more magnetic elements positioned around the first channel 212a. The magnetic assemblies 244a and 244b are designed to magnetically couple with magnetic elements or magnetically attractable materials in the electronic device 100 ( Figure 6 not shown) to hold a portion of the electronic device 100 within the first channel 212a. The second section 202b may also include magnetic assemblies 244c and 244d (both shown as dashed lines), each magnetic assembly including two or more magnetic elements positioned around the second channel 212b. The magnetic assemblies 244c and 244d are designed to magnetically couple with magnetic elements or magnetically attractable materials in the electronic device 100 ( Figure 6 not shown) to hold a portion of the electronic device 100 within the second channel 212b. Each of the magnetic assemblies 244a, 244b, 244c, and 244d may form a Halbach array, which is designed to provide an additional or increased external magnetic field at one location while providing a resulting reduced external magnetic field at another location. The additional or increased external magnetic field may pass through the first channel 212a and the second channel 212b to enhance the magnetic attraction between the magnets in the electronic device 100 and the aforementioned magnetic assemblies. This may allow for fewer magnetic elements along the first channel 212a and the second channel 212b, which may result in a smaller weight and a lower cost.

[0072] Based on the position of the electronic device 100 ( Figure 6 not shown) relative to the accessory device 200, it may be advantageous to selectively activate or deactivate the keyboard 208. In this regard, the accessory device 200 may include a sensor that is designed to detect an external magnetic field generated by magnetic elements in the electronic device 100 to determine the position of the electronic device 100. For example, the accessory device 200 may include a first sensor 232a and a second sensor 232b. The first sensor 232a and the second sensor 232b are designed to detect when the electronic device 100 is positioned in the first channel 212a and the second channel 212b, respectively, and provide an input to activate the electronic device 100. In some embodiments, the first sensor 232a and the second sensor 232b are Hall effect sensors that are designed to detect an external magnetic field generated by magnetic elements in the electronic device 100. The accessory device 200 may include a third sensor 232c that is designed to detect when the electronic device 100 is lying flat on the keyboard 208 and provide an input to deactivate the electronic device 100.

[0073] Referring again to Figure 3, the electronic device 100 may include a compass 146. When the electronic device 100 is positioned on the first section 202a ( Figure 6 ), at least some of the magnetic elements may provide an interfering external magnetic field that causes the compass 146 to inaccurately determine the Earth's magnetic field and thus inaccurately determine the correct direction (such as north, south, east, or west). Figure 6 The position 246 of the compass 146 superimposed on the first section 202a is shown. To cancel or neutralize any magnetic elements that may affect the compass 146, the accessory device 200 may include a first compensating magnetic element 248a and a second compensating magnetic element 248b. The first compensating magnetic element 248a and the second compensating magnetic element 248b may be modified to provide an external magnetic field ( Figure 6 ) that is not orthogonal or perpendicular to the surface defined by the first section 202a and the second section 202b (not shown in Figure 6 ), while the magnetic elements in the accessory device 200 may provide an external magnetic field ( Figure 6 ) that is generally orthogonal or perpendicular to the surface defined by the first section 202a and the second section 202b (not shown in ). Thus, the first compensating magnetic element 248a and the second compensating magnetic element 248b may offset the external magnetic field of the magnetic elements in the accessory device 200 such that the compass 146 operates properly. The first compensating magnetic element 248a and the second compensating magnetic element 248b are shown in the first section 202a and the second section 202b, respectively. However, other positions are possible.

[0074] Figure 7 A side view of the accessory device 300 shown in accordance with some of the described embodiments is shown, which shows the electronic device 100 coupled to the accessory device 200 and positioned in the first channel 212a. As shown, the magnetic element 140k interacts with the first magnet 254a and the second magnet 254b in the magnetic assembly 244a (also shown in Figure 6 ), which are also shown in Figure 6Magnetic coupling. When a force (in the direction of arrow 179a) is applied to the electronic device 100, the rotational force (in the direction of arrow 179b) can cause the electronic device 100 to move away from the first channel 212a. However, the magnetic assembly 244a can counteract this rotational force. For example, the size and shape of the first magnet 254a can be larger than the size and shape of the second magnet 254b. In this way, compared with the second magnet 254b, the first magnet 254a can include a stronger external magnetic field. The relatively strong external magnetic field of the first magnet 254a provides a force in the direction of arrow 179c that is opposite to the force in the direction of arrow 179b, thereby counteracting the rotational force. Moreover, the magnetic coupling between the magnetic element 140k and the second magnet 254b provides a force in the direction of gravity or at least approximately in the direction of gravity to hold the electronic device 100 in the first channel 212a. It should be noted that the magnetic assembly 244b (shown in Figure 6 may include multiple magnets and associated features described for the magnetic assembly 244a. In addition, the magnetic element 140l (shown in Figure 3 ) can be magnetically coupled to the magnetic assembly 244b.

[0075] As Figure 6 described, a magnetic assembly (such as the magnetic assembly 244a) can form a Halbach array to enhance magnetic attraction. The electronic device 100 can include a modified magnetic element to further enhance magnetic attraction. For example, the first magnet 254a and the second magnet 254b are polarized such that the magnetic field is orthogonal to the surfaces of the first magnet 254a and the second magnet 254b, as indicated by the arrows superimposed on the first magnet 254a and the second magnet 254b. However, the magnetic element 140k can be polarized to include some non-normal angles with respect to the surface of the magnetic element of the magnetic element 140k. As shown in the figure, the arrows superimposed on the magnetic element 140k indicate that the magnetic field is at an angle 183 that is non-orthogonal to the surface of the magnetic element 140k. In some embodiments, the angle 183 is 40 degrees. Generally, the angle 183 can be in the range of 30 degrees to 80 degrees.

[0076] Figure 8 shows Figure 6Side view of the accessory device 200 shown, which shows the electronic device 100 positioned in the second channel 212b. As shown, the magnetic element 140k is magnetically coupled to the first magnet 254c and the second magnet 254d of the magnetic assembly 244c. When a force (in the direction of arrow 179d) is applied to the electronic device 100, the electronic device 100 can be lifted out of the second channel 212b and away from the second section 202b. However, the magnetic assembly 244c can counteract this force. For example, the size and shape of the second magnet 254d can be larger than the size and shape of the first magnet 254c. In this way, compared to the first magnet 254c, the second magnet 254d can include a stronger external magnetic field. The relatively strong external magnetic field of the second magnet 254d provides a force in the direction of arrow 179e that is opposite to the force in the direction of arrow 179d, thereby counteracting this force. Moreover, the magnetic coupling between the magnetic element 140k in the electronic device 100 and the first magnet 254c provides a force to hold the electronic device 100 in the second channel 212b. It should be noted that the magnetic assembly 244d (shown in Figure 3 may include multiple magnets and the associated features described for the magnetic assembly 244c. In addition, the magnetic element 140l (shown in Figure 3 may be magnetically coupled to the magnetic assembly 244d.

[0077] Figure 7 And Figure 8 shows the first section 202a that supports the electronic device 100 in an upright configuration so that the user can interact with the keyboard 208 and the display assembly 104. In addition, the different sizes between the first section 206a and the second section 206b (i.e., the first section 206a is larger than the second section 206b) allow the first section 202a to be adjusted, thereby allowing the electronic device 100 to be positioned in the first channel 212a and the second channel 212b.

[0078] Figure 9 Isometric view of an alternative embodiment of the accessory device 300 according to some of the described embodiments. The accessory device 300 is designed to be used with the electronic device 100 and includes portable electronic devices such as mobile wireless communication devices and tablet devices. In this regard, the accessory device 300 can be referred to as a case, cover, protective cover, protective shell, folio, etc.

[0079] As shown, the accessory device 300 can include a first section 302a coupled to a second section 302b. The first section 302a can define a rear cover or rear panel for the electronic device 100. The first section 302a can define a receiving surface 304 that receives the electronic device 100, specifically, the receiving housing 102. In this regard, the first section 302a can hold the electronic device 100 by one or more magnets. This will be shown and discussed below. The first section 302a can also include an opening 316 or through-hole that is designed to receive the camera assembly 126, the flash module 128, and the microphone 129.

[0080] The second section 302b is designed to wrap around and cover the electronic device 100, including the display assembly 104. Thus, the second section 302b can be referred to as a front panel or front cover. The second section 302b can include multiple segments. For example, the second section 302b can include a first segment 306a, a second segment 306b, and a third segment 306c. Each segment can rotate or move relative to the remaining segments. Additionally, although in other embodiments, the discrete number of segments can vary.

[0081] The second section 302b is coupled to the first section 302a by a hinge 312 such that the first section 302a can rotate relative to the second section 302b and vice versa. The hinge 312 can be formed in part by one or more continuous pieces of material that extend along the first section 302a and the second section 302b. The material forming one or more layers can include a polymer that wraps a fiberglass material, such as polyurethane. However, in order to facilitate the flexibility and relative movement of the aforementioned sections and segments, the fiberglass material (and / or other relatively rigid or hard materials) can not be located at the hinge 312 and can not be located in positions between these segments. This will be shown and described below. Additionally, a soft non-abrasive such as microfiber can cover the first segment 306a, the second segment 306b, and the third segment 306c. Thus, when the second section 302b wraps around and covers the display assembly 104 (which can include a transparent cover stacked on top of the display assembly 104), the soft non-abrasive does not cause damage when in contact with the transparent cover or the display assembly 104.

[0082] Figure 10 Shown is Figure 9 A plan view of the accessory device 300 shown, which shows additional features in the accessory device. As shown, the accessory device 300 can include magnetic elements 340a, magnetic elements 340b, magnetic elements 340c, and magnetic elements 340d. The magnetic elements 340a, magnetic elements 340b, magnetic elements 340c, and magnetic elements 340d are designed to interact with the electronic device 100 (at Figure 3magnetically coupled as shown in to hold the electronic device 100 against the receiving surface 304. Thus, the first section 302a may not require mechanical features (such as retaining walls, sidewalls, or mechanical interlocks) to hold the electronic device 100. The magnetic elements for the accessory device 300 described herein may be represented by a rectangular structure. However, in terms of the number of rows and / or columns and the number of discrete magnetic elements, the magnetic elements include a layout / arrangement similar to Figure 3 the layout / arrangement of the magnetic elements shown for the electronic device 100 in. For example, the magnetic element 340a may include a layout / arrangement similar to the magnetic element 140a or the magnetic element 140c. However, the polarity of the discrete magnetic elements of the magnetic element 340a may be reversed so as to form a number of magnetic paths (with north-south pairs of magnetic attraction) between the magnetic element 340a and the magnetic element 140a.

[0083] The accessory device 300 may also include magnetic elements 340e, 340f, and 340g in the first section 302a, which are designed to be magnetically coupled to magnetic elements 340h, 340i, and 340j in the second section 302b, respectively. These magnetic couplings may occur, for example, when the second section 302b is rotated above and onto the receiving surface 304 or when the rear surface of the second section 302b (not shown in Figure 10 is rotated past and onto the rear surface of the first section 302a (not shown in Figure 10 ), where the rear surface of the first section 302a is opposite the receiving surface 304.

[0084] The accessory device 300 may also include magnetic elements 340k and 340l located in the first section 302a, which are designed to be magnetically coupled to magnetic elements 340m and 340n located in the second section 302b, specifically in the second segment 306b. The magnetic elements 340m and 340n are parallel (or aligned) to each other, while the magnetic element 340k is offset (or misaligned) relative to the magnetic element 340l. Additionally, the magnetic elements 340k and 340l are respectively offset relative to the magnetic elements 340m and 340n. However, the degree of offset between the magnetic element 340k and the magnetic element 340m may be different from the degree of offset between the magnetic element 340l and the magnetic element 340n. Thus, when the rear surface of the second section 302b is positioned against the rear surface of the first section 302a, the magnetic attraction between the magnetic element 340k and the magnetic element 340m may be different from the magnetic attraction between the magnetic element 340k and the magnetic element 340m. For example, the magnetic attraction between the magnetic element 340k and the magnetic element 340m may be greater than the magnetic attraction between the magnetic element 340k and the magnetic element 340m. Therefore, when the magnetic element 340k is no longer coupled to the magnetic element 340m, the magnetic element 340l is no longer coupled to the magnetic element 340n. This may be part of an integrated process, i.e., when pulling the first segment 306a away from the rear surface of the first section 302a, the second segment 306b and the third segment 306c are successively pulled away from the rear surface of the first section 302a, without the need for any additional force other than the force pulling the first segment 306a away from the rear surface of the first section 302a. In other words, when the first segment 306a is removed from the rear surface, the second segment 306b and the third segment 306c can automatically disengage from the rear surface.

[0085] The accessory device 300 may further include a magnetic element 340o located in the first section 302a, which is designed to be magnetically coupled with a magnetic element 340p located in the second section 302b, specifically in the third segment 306c. When the rear surface of the second section 302b is positioned against the rear surface of the first section 302a, the magnetic element 340o is magnetically coupled with the magnetic element 340p. In addition, when the rear surface of the second section 302b is rotated over and onto the rear surface of the first section 302a, the magnetic element 340p is magnetically coupled with the magnetic element 340o before the rear surface of the second section 302b is fully located on this rear surface. This magnetic coupling can provide a magnetic attraction force that pulls the second section 302b in a manner that aligns the rear surface of the second section 302b with the rear surface of the first section 302a, preventing misalignment between the rear surface of the second section 302b and the rear surface of the first section 302a. In other words, due to the magnetic coupling between the magnetic element 340o and the magnetic element 340p, the second section 302b will not bend relative to the first section 302a.

[0086] As described above, Figure 10 Some of the magnetic elements represented by rectangles as shown and described may include a number of discrete magnetic elements. By using a number of smaller discrete magnetic elements instead of fewer larger magnetic elements, the ease of aligning the electronic device 100 (shown in Figure 9 is improved. For example, each magnetic element provides a relatively small external magnetic field, thereby reducing the magnetic attraction force during alignment. However, these magnetic elements as a group (such as a cluster of magnetic elements 340a) can provide a combined external magnetic field similar to that of a single larger magnetic element. Compared with a large single magnet, this group of magnetic elements allows more movement, thus enhancing the alignment process.

[0087] The accessory device 300 may include certain dimensional features. For example, the first segment 306a may include a dimension 318a that is smaller than the dimension 318b of the second segment 306b and smaller than the dimension 318c of the third segment 306c. Additionally, the dimension 318b of the second segment 306b may be the same as or at least substantially similar to the dimension 318c of the third segment 306c. However, other dimensional relationships of the first segment 306a, the second segment 306b, and / or the third segment 306c are also possible.

[0088] Additionally, the accessory device 300 may include magnetic elements 340q, 340r, and 340s embedded in the first section 302a. In some cases, when the first segment 306a engages with the second segment 306b, the magnetic elements 340h, 340i, and 340j may be magnetically coupled with the magnetic elements 340q, 340r, and 340s, respectively.

[0089] Figure 11 An isometric view of an alternative embodiment of an accessory device 400 in accordance with some of the described embodiments is shown. The accessory device 400 is designed to be a complementary device to the electronic device 100. In this regard, the accessory device 400 may include a cover, a protective cover, a protective case, a folio, etc. As shown, the accessory device 400 includes a section 402. Although partially shown, the accessory device 400 may also include additional sections (similar to Figure 5 the second section 202b shown) connected to the section 402. The accessory device 400 may include a hinge 404 that connects the section 402 to the aforementioned additional section. The hinge 404 allows the section 402 to rotate or pivot relative to the aforementioned additional section, and vice versa. The hinge 404 may include a flexible material (such as polyurethane, as a non-limiting example) that defines one or more outer layers extending across the accessory device 400.

[0090] The section 402, also referred to as the first section, cover, cover portion, cover section, electronic device cover, or segmented cover, may define a receiving surface for the electronic device 100. The section 402 may include a first segment 406a rotatably coupled to a second segment 406b by a number of embedded hinges ( Figure 11 not shown) positioned between the first segment 406a and the second segment 406b. The embedded hinges allow rotational movement of the first segment 406a relative to the second segment 406b, and vice versa. The embedded hinges support the section 402 to hold the electronic device 100. Additionally, in some cases, the embedded hinges allow the section 402 to hold and suspend the electronic device 100 such that the electronic device 100 is suspended from the aforementioned additional section and does not contact it. Although a particular position of (the section 402) is shown, the section 402 is capable of rotating and repositioning the electronic device 100 whether or not the electronic device 100 is in contact with the aforementioned additional section. Additionally, to hold the electronic device 100, the first segment 406a may include a number of magnetic elements ( Figure 11 not shown). The first segment 406a may include any arrangement of the magnetic elements shown for the first segment 206a (shown in Figure 6 ). Alternatively, the first segment 406a may include any arrangement of the magnetic elements shown for the first segment 306a and the second segment 306b (shown in Figure 10 ).

[0091] In some embodiments, the first section 406a and the second section 406b generally have the same dimensions. In Figure 11 the illustrated embodiment, the first section 406a is larger than the second section 406b. Moreover, both the first section 406a and the second section 406b may include a microfiber layer (not labeled). In some cases, the microfiber layer is limited to the first section 406a and the second section 406b such that the microfiber layer does not cover the embedded hinge.

[0092] The section 402 may further include electrical contacts ( Figure 11 not shown in the figures), which are designed to engage with the electrical contacts 123 of the electronic device 100 (shown in Figure 3 the figures) and enable the accessory device 400 to communicate (including electrical communication) with the electronic device 100. As a non-limiting example, the foregoing additional section (also referred to as a keyboard section or a keyboard cover) may include a keyboard ( Figure 11 not shown in the figures), where a plurality of keys are arranged in a QWERTY configuration. When the accessory device 400 communicates with the electronic device 100, the keyboard can be used to provide inputs and commands to the electronic device 100 to control the display assembly 104 (illustrated as a dashed line) of the electronic device 100. The section 402 may further include an opening ( Figure 11 not shown in the figures) or a through hole, which is designed to receive the camera assembly 126, the flash module 128, and the microphone 129 (shown in Figure 2 the figures).

[0093] Figure 12 is shown Figure 11 a plan view of the illustrated accessory device 400, which shows several magnetic elements in the accessory device 400. As shown, the first section 406a may include magnetic elements 440a, magnetic elements 440b, magnetic elements 440c, and magnetic elements 440d. The magnetic elements for the accessory device 400 described herein may be represented by a rectangular structure. However, in terms of the number of rows and / or columns and the number of discrete magnetic elements, the magnetic elements include a layout / arrangement similar to that of the magnetic elements shown for the electronic device 100 in Figure 2 the figures. For example, the magnetic elements 440a may include a layout / arrangement similar to that of the magnetic element 140c. In some cases, the polarity of the discrete magnetic elements of the magnetic elements 440a may be reversed so as to form several magnetic paths (with north-south pairs of magnetic attraction) between the magnetic elements 440a and the magnetic element 140c. However, in some cases, the polarity of the discrete magnetic elements of the magnetic elements 440a is the same so as to magnetically repel (with north-north or south-south pairs of magnetic repulsion) between the magnetic elements 440a and the magnetic element 140c. This will be shown below.

[0094] Figure 13 shows Figure 12 a plan view of the accessory device 400 shown, which shows the electronic device 100 coupled to the accessory device 400. As shown, at least some of the magnetic elements of the electronic device 100 are aligned with the magnetic elements of the accessory device 400. For example, some of the magnetic elements 140c, magnetic elements 140b, magnetic elements 140e, and magnetic elements 140f of the electronic device 100 (also shown in Figure 3 ) are aligned with some of the magnetic elements 440a, magnetic elements 440b, magnetic elements 440c, and magnetic elements 440d of the accessory device 400, respectively. These "aligned" magnetic elements can be magnetically coupled to each other to hold the electronic device 100 and the accessory device 400 together. However, as shown, compared with the magnetic elements 140c, magnetic elements 140b, magnetic elements 140e, and magnetic elements 140f of the electronic device 100, the magnetic elements 440a, magnetic elements 440b, magnetic elements 440c, and magnetic elements 440d of the accessory device 400 include additional arrays (in this case, additional rows) of magnetic elements. For example, the magnetic elements 140c and magnetic elements 140b of the electronic device 100 include one array and two arrays of magnetic elements, respectively, while the magnetic elements 440a and magnetic elements 440b in the accessory device 400 include two arrays and three arrays of magnetic elements, respectively. The additional arrays of magnetic elements in the accessory device 400 can provide a magnetic repulsive force to at least some of the magnetic elements in the electronic device 100.

[0095] Figure 14 shows Figure 13 a side view of the accessory device 400 and the electronic device 100 shown, which shows that the magnetic elements in the accessory device 400 provide a magnetic repulsive force to the magnetic elements in the electronic device 100. As shown in the enlarged view, the magnetic element 140c includes a magnetic element 540a, and the magnetic element 540a is magnetically coupled to the magnetic element 640a of the magnetic element 440a in the accessory device 400 because the opposite magnetic poles are aligned. However, the magnetic element 440a of the accessory device 400 also includes a magnetic element 640b that magnetically repels the magnetic element 540a in the electronic device 100 because the same magnetic poles are aligned. The magnetic repulsion provides a force in the direction of arrow 480a (generally opposite to gravity) and provides an additional force to hold the electronic device 100 and the accessory device 400 together. It should be noted that the magnetic element 440a includes additional elements that are magnetically coupled to additional magnetic elements (similar to the magnetic element 640a and the magnetic element 540a) of the magnetic element 140c. Additionally, it should be noted that the magnetic element 440a includes additional elements that magnetically repel additional magnetic elements (similar to the magnetic element 640b and the magnetic element 540a) of the magnetic element 140c.

[0096] In addition, the magnetic component 140b includes magnetic components 540b and 540c, which are magnetically coupled to the magnetic components 640c and 640d of the magnetic component 440b in the accessory device 400, respectively, because the opposite magnetic poles are aligned. However, the magnetic component 440b of the accessory device 400 also includes a magnetic component 640e that magnetically repels the magnetic component 540c of the magnetic component 540c in the electronic device 100 because the same magnetic poles are aligned. The magnetic repulsion provides a force in the direction of arrow 480b (generally opposite to gravity) and provides an additional force to hold the electronic device 100 and the accessory device 400 together. It should be noted that the magnetic component 440b includes additional components that are magnetically coupled to additional magnetic components (similar to the magnetic components 640c and 540b) of the magnetic component 140b. Additionally, it should be noted that the magnetic component 440b includes additional components that magnetically repel the magnetic component 140b (similar to the magnetic components 640e and 540c). Although not shown, the relationship between the magnetic component 440d of the accessory device 400 and the magnetic component 140f of the electronic device 100 (shown in Figure 13 may be similar to the relationship between the magnetic component 440a and the magnetic component 140c. Moreover, although not shown, the relationship between the magnetic component 440c of the accessory device 400 and the magnetic component 140e of the electronic device 100 (shown in Figure 13 may be similar to the relationship between the magnetic component 440b and the magnetic component 140b.

[0097] Figures 15 - 17 Various configurations for the accessory device are shown and described. The accessory device 200 (shown in Figure 5 ), the accessory device 300 (shown in Figure 9 ), and the accessory device 400 (shown in Figure 11 ) can be configured as Figures 15 - 17 at least some of the configurations shown. Additionally, Figures 15 - 17 the accessory devices shown and described in Figure 5 may include several features (including magnetic components and the arrangement of magnetic components) described herein for the accessory device 200 (shown in Figure 9 ), the accessory device 300 (shown in Figure 11 ), and the accessory device 400 (shown in

[0098] Figure 15A side view of an accessory device 700 according to some of the described embodiments is shown, which shows the rear surfaces engaging with each other. As shown, the accessory device 700 includes a first section 702a and a second section 702b. The rear surface (or back surface) of the first section 702a engages with the rear surface (or back surface) of the second section 702b. The first section 702a can be held in engagement with the second section 702b by magnetic attraction. For example, the first section 702a includes a magnetic element 740a that is magnetically coupled to a magnetic element 742a in the configuration of the accessory device 700 shown in Figure 15 The additional magnetic elements (not labeled) in the first section 702a can be magnetically coupled to additional magnets (not labeled) in the second section 702b.

[0099] Figure 16 A side view of an embodiment of an accessory device 800 according to some of the described embodiments is shown, which shows an electronic device 900 positioned between and engaging with a first section 802a and a second section 802b of the accessory device 800. The electronic device 900 can include any of the features described herein for the electronic device 100 (shown in Figure 1 ). To maintain the engagement, the electronic device 100 can be magnetically coupled to both the first section 802a and the second section 802b. For example, the electronic device 900 includes a magnetic element 940a that is magnetically coupled to both a magnetic element 840a in the first section 802a and a magnetic element 842a in the second section 802b. In addition, the electronic device 900 can include a magnetic element 940b that is magnetically coupled to a magnetic element 842b positioned along the edge of the second section 802b. The electronic device 900 can include additional magnetic elements ( Figure 16 not shown herein), where each additional magnet is magnetically coupled to the edge magnets of the accessory device 800 (similar to the magnetic elements 242a, magnetic elements 242b, magnetic elements 242c, and magnetic elements 242d shown in Figure 6 ).

[0100] Moreover, in the configuration shown in Figure 16 , a first sensor 832a and / or a second sensor 832b of the accessory device 800 can detect an external magnetic field generated from one or more magnets in the electronic device 900, thereby generating subsequent commands to activate a keyboard (not labeled), even if the keyboard is not accessible. However, the accessory device 800 can include a third sensor 832c that is capable of detecting an external magnetic field from a magnetic element 940c. When the external magnetic field is detected, the third sensor 832c can send an input to a processor circuit on the circuit board of the electronic device 900 ( Figure 16(not shown in [the figure]). Then, the processor circuitry may generate a command to deactivate the keyboard. In other words, the input from the third sensor 832c may override the inputs from the first sensor 832a and the second sensor 832b. Thus, the accessory device 800 may initiate an inactive state of the electronic device 900 when the electronic device is covered and unavailable, as Figure 16 shown in

[0101] Figure 17 FIG. shows an accessory device coupled to an electronic device, according to some of the described embodiments, which shows the accessory device engaging and hanging on a magnetically attractable material 1080 in the accessory device. As a non-limiting example, the magnetically attractable material 1080 (illustrated as a dashed line) may be integrated with a blackboard, a dry-erase board, or a refrigerator. As shown, the magnetically attractable material 1080 is integrated with a vertically hanging dry-erase board 1082.

[0102] As shown, the accessory device 1000 includes a sufficient number of magnetic elements (such as magnetic element 1040a and magnetic element 1040b), which (collectively) generate an external magnetic field that can magnetically couple with the magnetically attractable material 1080 and support the weight of the accessory device 1000 and the electronic device 1100 (coupled to the accessory device 1000 via the magnetic elements), and counteract the effect of gravity. In some cases, the magnetic elements in the first zone 1002a alone provide an external magnetic field sufficient to support the weight of the accessory device 1000 and the electronic device 1100 and counteract the effect of gravity. In some cases, the magnets in the second zone 1002b alone provide an external magnetic field sufficient to support the weight of the accessory device 1000 and the electronic device 1100 and counteract the effect of gravity. As shown, the accessory device 1000 is similar to the accessory device 200 (shown in Figure 5 ). However, the accessory device 300 (shown in Figure 9 ) and the accessory device 400 (shown in Figure 11 ) may provide the same capabilities as the accessory device 1000.

[0103] In addition, the accessory device 1200 may cover the electronic device ( Figure 17 not shown in [the figure]) and rely on the magnetic elements (not labeled) in a single zone (such as zone 1202a) to magnetically couple with the magnetically attractable material 1080 and resist gravity to remain hanging. As shown, the accessory device 1200 is similar to the accessory device 300 (shown in Figure 9 ). However, the accessory device 200 (shown in Figure 5 ) and the accessory device 400 (shown in Figure 11 ) may provide the same capabilities as the accessory device 1000.

For example, the user input device 1308 may take various forms, such as buttons, keypads, dials, touchscreens, audio input interfaces, visual / image capture input interfaces, input in the form of sensor data, etc. Further, the electronic device 1300 may include a display 1310 (screen display) that can be controlled by the processor 1302 to present visual information to the user. A data bus 1316 may facilitate data transfer between at least the storage device 1340, the processor 1302, and the controller 1313. The controller 1313 may be used to interact with and control different devices via a device control bus 1314. The electronic device 1300 may also include a network / bus interface 1311 coupled to a data link 1312. In the case of a wireless connection, the network / bus interface 1311 may include a wireless transceiver.

[0106] The electronic device 1300 further includes a storage device 1340, which may include a single disk or multiple disks (e.g., a hard disk drive), and includes a storage management module that manages one or more partitions within the storage device 1340. In some embodiments, the storage device 1340 may include flash memory, semiconductor (solid-state) memory, etc. The electronic device 1300 may also include a random access memory (RAM) 1320 and a read-only memory (ROM) 1322. The ROM 1322 may store programs, utilities, or processes to be executed in a non-volatile manner. The RAM 1320 may provide volatile data storage and store instructions related to the operation of the electronic device 1300.

The various aspects of the embodiments may be implemented by software, hardware, or a combination of hardware and software. The embodiments may also be implemented as computer-readable code on a computer-readable medium for controlling a production operation, or as computer-readable code on a computer-readable medium for controlling a production line.
