## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
The present application claims the benefit of U.S. Provisional Patent Application No. 62/207,362 filed on Aug. 19, 2015, the disclosure of which is expressly incorporated herein by reference in its entirety. This application also claims the benefit of U.S. Provisional Patent Application No. 62/210,944 filed on Aug. 27, 2015, the disclosure of which is expressly incorporated herein by reference in its entirety.


1. Field
The disclosure relates generally to cases and, in particular embodiments, to protective cases for mobile electronic communication devices.
2. Background
Mobile electronic communication devices, such as smart phones, tablets, or the like, typically contain sensitive and/or delicate electronics or other components. These devices can be subject to physical abuse and risks of damage from handling, especially given the portable nature of the devices (e.g., dropping, or otherwise subjecting the devices to physical shock or other trauma, etc.). In addition, because they contain sensitive electronics, mobile electronic communication devices are particularly susceptible to damage caused by liquids (e.g., a mobile phone may be rendered completely inoperable after being exposed to water). Mobile electronic communication devices typically include housings that can withstand a certain level of physical shock or water exposure. However, in an effort to improve aesthetics, the housings are typically designed to have finishes that look appealing, but often at the compromise of structural integrity. Accordingly, a protective case that encloses some or the entire mobile electronic communication device can provide an additional level of protection to the sensitive electronics and the housing of the mobile electronic communication device.

Referring to FIGS. 1-5B, according to various embodiments, the protective case 100 includes the rear cover 110 and the front cover 120 that, when coupled, form a volume in the protective case 100. The volume of the protective case 100 may be configured to hold a mobile electronic communication device (not shown), such as, but not limited to, a smart phone (e.g., iPhone) or other cell phone, a tablet (e.g., iPad), a personal data assistant (PDA), a laptop, an MP3 player, a music player, a video player, a media player, a navigational device, a telematics devices, or any other portable electronic device. The mobile electronic communication device may include a display device (e.g., LCD screen, etc.), a user input interface (e.g., keyboard, touchscreen interface, etc.) for providing an input or otherwise interacting with the mobile electronic communication device, and/or the like. In particular embodiments, the mobile electronic communication device includes a touchscreen for the display device and the user input interface.
In various embodiments, the rear cover 110 and/or the front cover 120 may be made of any suitable material. In particular embodiments, the rear cover 110 and/or the front cover 120 may be made from materials that are capable of providing one or more of shock and liquid resistance to an encased mobile electronic communication device, when the rear cover 110 and the front cover 120 are coupled around the encased device. In some embodiments, the rear cover 110 and the front cover 120 are composed of a plurality of different components and therefore may be fabricated from a plurality of different materials. Suitable materials from which the rear cover 110 and/or the front cover 120 may be made of include, but are not limited to, rigid, semi-rigid, flexible, or any other type of material adapted to provide a corresponding desired amount of protection to the mobile electronic communication device (e.g., shock and/or liquid resistance) including, but not limited to, plastic, metal, polycarbonate, nylon, liquid crystal polymer, rubber, thermal plastic urethane, polyethylene, polypropylene, a combination thereof, a mixture thereof, and/or the like.
In various embodiments, the protective case 100 completely encloses the mobile electronic communication device. For instance, the rear cover 110 and the front cover 120, when coupled together, may completely enclose the mobile electronic communication device. In other embodiments, the protective case 100 covers a portion of the mobile electronic communication device. In such embodiments, a remaining portion of the mobile electronic communication device may remain exposed.
According to various embodiments, the front cover 120 includes an outer body 121. The outer body 121 may form the perimeter of the protective case 100 such that the outer body 121 encompasses the edges of a mobile device when the mobile device is encased in the protective case 100. The outer body 121 may include an outer peripheral wall 121a facing towards an outside of the protective case 100, and an inner peripheral wall 121b facing the opposite direction from which the outer peripheral wall 121a faces (e.g., towards the mobile electronic communication device when the device is encased in the protective case 100). The inner peripheral wall 121b may define a cavity 122 in which the mobile electronic communication device may reside. In such embodiments, the outer peripheral wall 121a and the inner peripheral wall 121b of the outer body 121 form a peripheral wall 120a of the front cover 120. In some embodiments, the outer peripheral wall 121a and the inner peripheral wall 121b are made from the same material. In other embodiments, the outer peripheral wall 121a and the inner peripheral wall 121b are made from different materials. The outer peripheral wall 121a and the inner peripheral wall 121b may be made from any suitable material for providing protection to the encased mobile electronic communication device, such as, but not limited to, an elastomeric material, plastic, metal, polycarbonate, nylon, liquid crystal polymer, rubber, thermal plastic urethane, polyethylene, polypropylene, a combination thereof, a mixture thereof, and/or the like.
In various embodiments, the outer body 121 of the front cover 120 further includes a liner 130 located between the outer peripheral wall 121b and the inner peripheral wall 121a. The liner 130 may extend along the perimeter of the peripheral wall 120a. In some embodiments, the outer peripheral wall 121a and the inner peripheral wall 121b may be coupled to each other by one or more channels 121c. Each of the one or more channels 121c may be located through the liner 130 to form a connection between the outer peripheral wall 121a and the inner peripheral wall 121b, which are otherwise isolated from each other by the liner 130. In some embodiments, each of the one or more channels 121c is periodically located throughout the perimeter of the liner 130, at discrete locations throughout the liner 130. In particular embodiments, the one or more channels 121c are arranged throughout the perimeter of the liner 130 in a regular or irregular pattern. In other embodiments, the one or more channels 121c include a continuous channel extending along the perimeter of the liner 130, as opposed to the one or more channels 121c being located at discrete locations, such that the outer peripheral wall 121a and the inner peripheral wall 121b are continuously coupled through the liner 130 along the perimeter of the outer body 121. The liner 130 may be made from any suitable sturdy material, such as, but not limited to, plastic, metal, polycarbonate, nylon, liquid crystal polymer, rubber, thermal plastic urethane, polyethylene, polypropylene, a combination thereof, a mixture thereof, and/or the like. In particular embodiments, the liner 130 and the peripheral wall 120a may be formed together (e.g., using an overmold process). In other embodiments, the peripheral wall 120a and the liner 130 are made separately and joined together.
In further embodiments, the liner 130 extends upward through a top perimeter (e.g., a location opposite the rear cover 110 when the front cover 120 and the rear cover 110 are coupled) of the outer body 121 and forms an annular ledge 130a of the liner 130 around the top perimeter of the outer body 121. The ledge 130a may be substantially flat along the top perimeter of the outer body 121 and extend inwards towards the cavity 122 and over the inner peripheral wall 121b. In some embodiments, the ledge 130a is formed as an extension of the liner 130 and may therefore be made from the same material as that of the liner 130. In other embodiments, the ledge 130a is formed separately and attached to the liner 130. In such embodiments, the ledge 130a may be formed of any suitable material the same as, or different from, the liner 130, such as, but not limited to, plastic, metal, polycarbonate, nylon, liquid crystal polymer, rubber, thermal plastic urethane, polyethylene, polypropylene, a combination thereof, a mixture thereof, and/or the like.
In further embodiments, the liner 130 also extends downwards through a bottom perimeter (e.g., a perimeter located opposite the annular ledge 130a) of the outer body 121 and forms an annular rim 130b of the liner 130 along the bottom perimeter of the outer body 121. In particular embodiments, the rim 130b extends beyond the peripheral wall 120a of the outer body 121. The rim 130b may include an outer surface 131 for engagement with the rear cover 110 and an inner surface 132 opposite the outer surface 131 for engagement with a seal located on the rear cover 110. In such embodiments, the outer surface 131 includes an angular recess 131a for engagement with the rear cover 110. Furthermore, the inner surface 132 may be a substantially flat or level surface. In some embodiments, the rim 130b is formed as an extension of the liner 130 and is therefore made from the same material as that of the liner 130. In other embodiments, the rim 130b is formed separately and attached to the liner 130. In such embodiments, the rim 130b may be formed of any suitable material the same as, or different from, the liner 130, such as, but not limited to, plastic, metal, polycarbonate, nylon, liquid crystal polymer, rubber, thermal plastic urethane, polyethylene, polypropylene, a combination thereof, a mixture thereof, and/or the like.
A mobile electronic communication device may be mounted or otherwise arranged in the protective case 100 in any suitable manner. In some embodiments, the mobile electronic communication device may be received in the front cover 120. For instance, the peripheral wall 120a defines the cavity 122 for receiving (at least a portion of) the mobile electronic communication device. In other embodiments, the mobile electronic communication device is mounted to the protective case 100 by attaching the mobile electronic communication device to the protective case 100, for example, with a fastener, adhesive, and/or the like.
In various embodiments, the rear cover 110 and the front cover 120 are configured to couple or mate in any suitable manner to enclose the mobile electronic communication device in the protective case 100. In particular embodiments, at least a portion of the rear cover 110 is received into a portion (e.g., cavity 122) of the front cover 120.
In some embodiments, the rear cover 110 and the front cover 120 are configured to be coupled together to form a waterproof seal (i.e., to substantially prevent passage of liquid from one side of the protective case 100 (e.g., outside of the protective case 100) to the other side of the protective case 100 (e.g., inside of the protective case 100)). In some embodiments, an annular compressible member 150 is provided on the rear cover 110 to provide a seal between the rear cover 110 and the front cover 120, when the rear cover 110 and the front cover 120 are coupled to each other. The annular compressible member 150 may extend along a perimeter (e.g., the entire perimeter or a portion of the perimeter) of the rear cover 110, at a location inwards from an edge 112 of the rear cover 110. In particular embodiments, the compressible member 150 is attached to a front surface 110a of the rear cover 110 facing the cavity 122. For instance, the compressible member 150 may be attached by, for example, but not limited to, overmolding the compressible member 150 onto the rear cover 110, an adhesive material, one or more fasteners, a combination thereof, and/or the like, to the front surface 110a or the rear cover 110. In various embodiments, the compressible member 150 is shaped and dimensioned to correspond to a shape and dimension of an outer perimeter of the mobile electronic communication device, or one or more portions of such outer perimeter. In some embodiments, the compressible member 150 may be a gasket (e.g., O-ring) or the like for providing a seal between the rear cover 110 and the front cover 120 when the rear cover 110 is coupled to the front cover 120. In particular embodiments, the compressible member 150 is made of a pliable material, such as, but not limited to, liquid silicone rubber (LSR), microcellular urethane (e.g., PORON®), and/or the like.
In some embodiments, the compressible member 150 may include an enlarged portion 150a and a projection portion 150b extending outwards from the enlarged portion 150a (e.g., towards the edge 112 of the rear cover 110). In some embodiments, the projection portion 150b extends into the alcove 113. In some embodiments, the rear cover 110 may include an inclined surface 114 around a perimeter of the rear cover 110 located inwards from the edge 112 of the rear cover 110. The location of the inclined surface 114 may substantially correspond to the enlarged portion 150a of the compressible member 150. In some embodiments, the enlarged portion 150a may have grooves for accommodating pillars that extend upwards from the inclined surface 114 (see e.g., FIG. 6B), for maintaining and stabilizing the compressible member 150. In further embodiments, the inclined surface 114 extends at a predefined angle for a predefined length along the rear cover 110. At the edge 112, the rear cover 110 may include a protruding surface 112a extending from the inclined surface 114 and substantially corresponding to the projection portion 150b of the compressible member 150. In some embodiments, the protruding surface 112a extends in a downward direction (e.g., in a direction opposite the encased mobile electronic communication device) such that the protective case 100, when lying flat, will stand and contact the surface on which it lays at the protruding surface 112a. Furthermore, because the protective case 100 may stand upright via the annular protruding surface 112a, there will be a volume of empty space present underneath the protective case 100, for example, substantially underneath a flat surface 116 extending from the inclined surface 114, opposite the protruding surface 112a. This volume of empty space allows for improved quality of sound and acoustics originating from the encased mobile electronic communication device.
In addition, in some embodiments, because the compressible member 150 is substantially located on the inclined surface 114 of the rear cover 110, this allows the pressure exerted by the compressible member 150 against the inner surface 132 of the rim 130b to be directed or focused downwards and towards the rim 130b, resulting in a stronger seal. Furthermore, in some embodiments, the compressible member 150 takes the form of a ring around the perimeter of the rear cover 120, which protrudes upwards towards the front cover 120 above the front surface 110a of the rear cover 110. Accordingly, in some embodiments, the mobile electronic communication device, when resting atop the rear cover 110 will be suspended above the front surface 110a of the rear cover 110, such that there will be a gap of empty space underneath the device when inside the protective case. By accommodating for a space or gap between the mobile electronic communication device and the front surface 110a of the rear cover 110, the protective case 100 allows for improved sound quality and acoustics originating from the encased mobile electronic communication device.
In further embodiments, the projection portion 150b of the compressible member 150 contacts (e.g., engages or abuts) the inner surface 132 of the rim 130b of the front cover 120 to form a seal between the compressible member 150 and the inner surface 132 of the rim 130b of the front cover 120 when the rear cover 110 and the front cover 120 are coupled to each other. In such embodiments, when the rear cover 110 and the front cover 120 are not coupled to each other (e.g., they are separated), the rear cover 110 may include an alcove 113 between the compressible member 150 and the edge 120 for accommodating the rim 130b. The alcove 113 may have enough space for allowing the rim 130b to both clasp with the rear cover 110 (at one side of the rim 130b at the outer surface 131) and compress the compressible member 150 for sealing (at the opposite side of the rim 130b at the inner surface 132). In such embodiments, the compressible member 150 compresses away from the inner surface 132 of the rim 130b towards the enlarged portion 150a (e.g., up the inclined surface 114) such that the projection portion 150b is in a state that is flush (e.g., compressed) against the inner surface 132 of the rim 130b. Accordingly, the excess material of the compressible member 150 that is compressed up the inclined surface 114 may transfer to the enlarged portion 150a of the compressible member 150 and increase the thickness of the enlarged portion 150a. In such embodiments, when the rear cover 110 and the front cover 120 are coupled to each other, there may be provided at least one empty space 117 above and/or below the compressible member 150 such that the transferred material of the compressible member 150, when the compressible member 150 is in a compressed state, may be accommodated within the protective case 100. By exerting force against the compressible member 150 such that it is in a compressed state, the seal strength may be increased to further inhibit passage of fluid, dust, or the like, between the compressible member 150 and the front cover 120. According to various embodiments, when the front cover 110 and the rear cover 120 are coupled together, an enclosed volume is formed for holding the mobile electronic communication device. In some embodiments, the compressible member 150 may be made from liquid silicone rubber, which may provide improved memory characteristics for maintaining the seal of the protective case 100.
In further embodiments, while the inner surface 132 of the rim 130b is configured to interact or engage with the compressible member 150 for sealing the protective case 100, the outer surface 131 of the rim 130b may be configured to interact or engage with the rear cover 110 to fasten or clasp the front cover 120 together with the rear cover 110. In some embodiments, the edge 112 of the rear cover 110 includes a catch 112b. The catch 112b may correspond to a shape of the angular recess 131a at the outer surface 131 of the rim 130a such that the angular recess 131a and the catch 112b interlock with each other to secure the coupling of the rear cover 110 with the front cover 120. In various embodiments, when the front cover 120 is not coupled to the rear cover 110, there may be an alcove 113 between the compressible member 150 and the catch 112b for accommodating the rim 130b when the front cover 120 is coupled to the rear cover 110. In other words, the compressible member 150 and the catch 112b may be spaced from each other to form the alcove 113, which is configured to accommodate the rim 130b. It should be noted that such coupling configurations for the rear cover 110 and the front cover 120 are examples, and other embodiments may implement other suitable coupling configurations, such as, but not limited to, different corresponding angles and/or shapes of the angular recess 131a and the catch 112b (e.g., male and female plugs), other coupling mechanisms (e.g., friction fitting, snap fitting, clasping mechanism, clamping/fastening member, and/or the like), etc. In further embodiments, the coupling locations between the rear cover 110 and the front cover 120 may be discrete and periodic along the perimeter of the protective case 100, instead of a continuous system throughout the perimeter.
In yet further embodiments, the inner surface 132 and the outer surface 131 of the rim 130b may be designed differently from each other, as they provide different functions (e.g., the inner surface 131 is configured to seal against the compressible member 150 and the outer surface is configured to clasp and engage the rear cover 110 for latching the front cover 120 and the rear cover 110 together). As such, in some embodiments, the inner surface 132 may have a smooth and level shape (e.g., flat), so as to not be abrasive against the compressible member, and the outer surface 131 may have a more contoured shape (e.g., jagged or angular shape) for suitably latching and maintaining the connection to the catch 112b of the rear cover 110.
According to some embodiments, the front cover 120 includes a membrane 140 that allows access to the front surface of the mobile electronic communication device, such as the user input interface (e.g., touchscreen interface) of the mobile electronic communication device, one or more of the operators, and/or the like of the mobile electronic communication device, through the membrane 140 provided over at least a portion of the mobile electronic communication device. In some embodiments, the membrane 140 includes at least one aperture 118 (or otherwise provides access) for allowing access to at least one other portion of the mobile electronic communication device, such as, but not limited to, one or more of a front-facing camera, microphone, speaker, proximity sensor, etc.
In particular embodiments, the rear cover 110 and the front cover 120, when coupled together, along with the membrane 140, completely enclose the mobile electronic communication device. The membrane 140 may be a sheet of thin plastic or other suitable material, for example, that allows interaction with an encased mobile electronic communication device (e.g., the touchscreen display of the encased mobile electronic communication device). The membrane 140 may be transparent (or at least partially transparent) to allow images displayed on the touchscreen display of the mobile electronic communication device to be visible through the membrane 140. The configuration (e.g., size, thickness, layout, composition etc.) of the membrane 140 may be based on a particular manufacturer or model of the encased mobile electronic communication device.
According to various embodiments, the membrane 140 is fixed by, for example, but not limited to, adhesive, surface tension, friction, static cling, viscous fluid, one or more fasteners, a combination thereof, and/or the like, to one or more of the protective case 100 (e.g., the front cover 110, the rear cover 120, etc.) or the mobile electronic communication device. In some embodiments, the membrane 140 is affixed to the annular ledge 130a. In such embodiments, the membrane 140 may be affixed to the ledge 130a via an annular fastener 142 disposed between the membrane 140 and the annular ledge 130a. In various embodiments, the annular fastener 142 may be any suitable material for securing the membrane 140 to the annular edge 130a, such as, but not limited to, double-sided tape, pad print adhesive, and/or the like. By affixing the membrane 140 on top of the outer body 121 (e.g., as opposed from the bottom of the outer body 121 within the cavity 122), the membrane 140 may be more uniformly and easily affixed at the annular fastener 142 during a manufacturing process of the protective case 100 (e.g., by a roller machine configured to apply uniform pressure throughout the perimeter of the membrane at the annular fastener 142). In other embodiments, the membrane 140 is not fixed to the protective case 100 or the mobile electronic communication device. That is, the membrane 140 may be a separate component from the rear cover 110 and the front cover 120. In such embodiments, the membrane 140 may be held in place against the mobile electronic communication device by coupling (e.g., clamping, fastening, adhesive, etc.).
In various embodiments, the membrane 140 is located over the front surface of the mobile electronic communication device received in the protective case 100 and rests on the front surface of the mobile electronic communication device to allow user interaction with the user input interface of the mobile electronic communication device through the membrane 140. In particular embodiments, a rear surface 140a (the surface facing downwards in the orientation of FIG. 4) of the membrane 140 is arranged to contact the front surface of the encased mobile electronic communication device. According to various embodiments, the membrane 140 may be made of any suitable transparent and lightweight material, such as, but not limited to, glass, plastic, vinyl, and/or the like.
The mobile electronic communication device may include at least one camera or other video/image/data capture device. In particular embodiments, the protective case 100 is configured to allow an image or the like to be captured through the protective case 100. In particular embodiments, the rear cover 110 includes one or more openings 139 arranged to align with a lens of a rear-facing camera and/or a light source (e.g., for providing flash photography in conjunction with the rear-facing camera) of the mobile electronic communication device. In further embodiments, the one or more openings 139 is covered by a transparent portion (e.g., an optically clear lens) arranged to align with the camera lens, the light source, and/or the like. The transparent portion may be formed as an integral feature of the protective case 100 or may be a separate part formed separately and assembled to the protective case 100. In some embodiments, the protective case 100 includes a movable door arranged over the lens to selectively open to allow the camera to capture an image of an object outside the protective case 100. In some embodiments, the front cover 120 may be configured to allow an image or the like to be captured through the protective case 100 by a front-facing camera. For example, the front cover 110 may include an aperture or otherwise provide access to the front-facing camera of the mobile electronic communication device (e.g., through the transparent membrane 140 itself). In further embodiments, the one or more openings 139 and/or the aperture for the front-facing camera may be surrounded by a gasket (e.g., O-ring) or the like for providing a seal at the openings and/or aperture. In particular embodiments, the gasket is made of a pliable material, such as, but not limited to, liquid silicone rubber, microcellular urethane (e.g., PORON®), and/or the like.
The mobile electronic communication device may have one or more indicator lights on one or more suitable portions of the mobile electronic communication device to indicate information, such as a status light for power, communication, battery status, or other functions (e.g., new voicemail, email, text message, or other message). In some embodiments, the indicator lights may be in positions on the mobile electronic communication device that are not readily viewable through the membrane 140 or other portion of the protective case 100. In particular embodiments, the protective case 100 may be configured to allow the indicator lights to be visible through at least a portion of the protective case 100. For example, the rear cover 110 and/or the front cover 120 of the protective case 100 may include one or more transparent portions, light pipes, or the like that transmit light from the mobile electronic communication device to outside of the protective case 100. The transparent portions may be constructed of a transparent (or semi-transparent) material. The transparent portions may be formed as an integral feature of the protective case 100 or may be separate parts that are formed separately and assembled to the protective case 100. In other embodiments, the indicator lights of the mobile electronic communication device are visible to outside of the protective case 100 through the membrane 140 itself. According to various embodiments, the transparent portions may be made of any suitable transparent material, such as, but not limited to, glass, plastic, vinyl, and/or the like.
The mobile electronic communication device may further include one or more audio devices, such as speakers, headphone jacks, microphones for receiving audio signals, etc. In particular embodiments, the protective case 100 may be configured to transmit audio signals through the protective case 100 to/from the one or more of the audio devices. For example, the rear cover 110 and/or the front cover 120 of the protective case 100 may include one or more openings 128 to the one or more of the audio devices. In further embodiments, the opening 128 includes a plug 128a to selectively open to allow access to the opening 128 for the speaker, microphone jack, and/or the like. In particular embodiments, the plug 128a is configured to pivot, slide, hinge, or open in any suitable manner that allows access to the opening 128. In some embodiments, the plug 128 may include an annular gasket 128b (e.g., O-ring) configured to surround a portion of the plug. The gasket 128b may be configured to seal (e.g., from liquid) the opening 128 when the plug 128a is situated within the opening 128. In some embodiments, the plug 128a has a threaded screw-like extension corresponding to the threaded opening 128, such that the plug 128a may be rotated into the opening for providing additional sealing and protection to the encased electronic mobile communication device. In other embodiments, the plug 128a is not threaded, but is configured to tightly fit in the opening 128 for suitably sealing the opening 128. In further embodiments, the plug 128a is fastened to the protective case 100 by a tether 128c. The tether 128c may be made from any suitable material for securing the tether 128c to the protective case 100, such as, a rigid material (e.g., plastic, polycarbonate, etc.) or a non-rigid material (e.g., string, fabric, rubber, etc.).
In other embodiments, the protective case 100 includes a film, membrane, or other material adapted to allow sound to pass through the film to or from one or more of the audio devices, yet inhibit passage of fluid, dust, or the like to the audio devices. For example, the membrane 140 includes the at least one aperture 118 over a speaker of the mobile electronic communication device. A film 146 may be provided over the at least one aperture 118 to allow sound to pass through the at least one aperture 118 and the film 146. In some embodiments, the film 146 is attached (e.g., via an adhesive, fastener, etc.) to a rear surface 140a of the membrane 140. In such embodiments, the film 146 is arranged between the mobile electronic communication device and the membrane 140. In other embodiments, the film 146 is attached to a front surface 140b of the membrane 140. In other embodiments, the film 146 is an integral part of the membrane 140. In some embodiments, the film 146 is configured to inhibit or prevent liquid, dust, and/or the like from penetrating the protective case 100 at the at least one aperture 118. According to various embodiments, the film 146 may be made of any suitable light material for protecting the sensitive electronics of the encased mobile device, such as, but not limited to, a hydrophobic polymer, and/or the like.
The mobile electronic communication device may have at least one interface for communicating with another device (e.g., a computer, a speaker, a charging device, etc.) and/or for charging the mobile electronic communication device. The interface may be a direct electrical connection, such as through a cable, for example (but not limited to) a USB cable and/or the like. Alternatively, or in addition, the interface may be a wireless connection, for example (but not limited to) Wi-Fi, Bluetooth, and/or the like. In particular embodiments, the protective case 100 may be configured to allow access to one or more of the interfaces, such as an interface that allows for a direct electrical connection. For example, the protective case 100 may include an interface opening 129 that aligns with the interface of the mobile electronic communication device when the mobile electronic communication device is received in the cavity 122 of the protective case 100. In further embodiments, the interface opening 129 may include a door 129a or the like for allowing selective access to the interface opening 129 to the interface of the mobile electronic communication device. In particular embodiments, the door 129a is configured to pivot, slide, hinge, or open in any suitable manner that allows access to the opening 129. The door may be made from any suitable material for adequately sealing the opening 129, such as, but not limited to, rubber, plastic, etc.
The mobile electronic communication device may include one or more operators (e.g., buttons, switches, etc.) as part of the user input interface for the mobile electronic communication device. The operator(s) may provide various functions, such as, but not limited to, powering on/off the mobile electronic communication device, changing a volume of the mobile electronic communication device, toggling audio/vibration (e.g., ringer of the mobile electronic communication device), or performing other functions on the mobile electronic communication device (e.g., a “Home” button). The button sizes, quantity, layouts, and functions may vary for each manufacturer and model of the mobile electronic communication device.
As such, in various embodiments, the protective case 100 may be configured to allow actuation of one or more operators of the mobile electronic communication device while the mobile electronic communication device is encased in the protective case 100. For instance, the protective case 100 may include one or more members or other features that are arranged to interact with one or more of the mobile electronic communication device operators. In some embodiments, a moveable member may be provided on the protective case 100 at a position to interact with the one or more operators of the mobile electronic communication device (received in the cavity 122) to transmit mechanical motion from outside of the protective case 100 to the one or more operators of the mobile electronic communication device. In particular embodiments, the moveable member may be a flexible or pliable member or portion of the protective case 100.
In one embodiment, the moveable member may include a flexible member 111, which may be arranged in the front cover 120 to transmit a force applied to the flexible member 111 to a Home button of the mobile electronic communication device located on a front surface of the mobile electronic communication device. In some embodiments, the flexible member 111 is also configured to allow sensing electronics of the mobile electronic communication device, beneath the flexible member 111, to sense characteristics beyond the flexible member. For example, the sensing electronics may include a biometric scanner for scanning and recognizing a fingerprint of a user, and the flexible member 111 may be configured to substantially allow the fingerprint scanner to function through the flexible member 111. In particular embodiments, the flexible member 111 may be suitably thin to allow the sensing electronics to properly function. According to various embodiments, the flexible member 111 may be made of any suitable flexible material, such as, but not limited to, liquid silicone rubber (LSR), microcellular urethane (e.g., PORON®), and/or the like.
In some embodiments, the moveable member may be a moveable body, such as a plunger or the like, configured to transmit mechanical movement from outside of the protective case 100 to one or more of the operators of the mobile electronic communication device. For example, a plunger 127 may be provided in the front cover 120 to transmit a force applied to the plunger 127 to a power or sleep/wake button of the mobile electronic communication device. As another example, a first button plunger 123a (e.g., corresponding to a volume up button of the mobile electronic communication device) and a second button plunger 123b (e.g., corresponding to a volume down button of the mobile electronic communication device) may be provided in the front cover 120 to transmit a force, applied to the first button plunger 123a or the second button plunger 123b, to the volume up button or volume down button of the mobile electronic communication device. Thus, in various embodiments, movement of a feature of the protective case 100 may move in a same (or parallel) direction as a direction in which a corresponding operator of the mobile electronic communication device is moved. According to various embodiments, the button plungers may be made of any suitable flexible or pliable material, such as, but not limited to, liquid silicone rubber (LSR), microcellular urethane (e.g., PORON®), and/or the like.
In other embodiments, the protective case 100 is configured to provide access to one or more of the mobile electronic communication device operators. For example, the protective case 100 may include an opening to allow a user to access (e.g., actuate) one or more of the mobile electronic communication device operators. It should be noted that the mobile electronic communication device may include any suitable type or number of operators, and/or the protective case 100 may include any suitable type or number of members arranged to interact with such operators. For example, the protective case 100 may include a pivoting or rocking member for actuating (at least) two of the operators (e.g., the volume up button and volume down button) of the mobile electronic communication device.
FIG. 6A is a view of a front cover of another protective case 600 according to various embodiments. FIG. 6B is a cross-section view of a portion of the protective case 600 according to various embodiments.
Referring to FIGS. 1-6B, in some embodiments, the protective case 600 may be configured to allow actuation of one or more switches of the mobile electronic communication device while the mobile electronic communication device is encased in the protective case 600. For instance, the protective case 600 may include one or more members or other features that are arranged to interact with one or more of the mobile electronic communication device switches. In some embodiments, a moveable member may be provided on the protective case 600 at a position to interact with the one or more switches of the mobile electronic communication device (received in the cavity 122) to transmit mechanical motion from outside of the protective case 600 to the one or more switches of the mobile electronic communication device. In particular embodiments, the moveable member may be a rigid laterally movable switch of the protective case 100. For example, at least one switch 125 may be arranged in the front cover 120 to transmit a force applied to the at least one switch 125 to a switch of the mobile electronic communication device located on a side surface of the mobile electronic communication device.
In some embodiments, the protective case 100 includes the at least one switch 125 configured to transmit mechanical movement to a corresponding operator of the mobile electronic communication device, such as, but not limited to, an audio/vibration (AV) switch 12. The switch 125 may be located in correspondence with the AV switch 12 of the mobile electronic communication device. For example, the switch 125 may be located at the same side of the outer body 121 as the button plungers 123a and 123b are located, and may be proximate the button plungers 123a and 123b. In some embodiments, the switch 125 may be configured for linear movement relative to a linear dimension (e.g., height dimension) of the mobile electronic communication device. In other embodiments, the switch 125 may be configured to pivot about an axis to interact with a switch of the mobile communication device. For instance, the AV switch 12 may be configured for movement in a first direction (e.g., toward a front surface of the mobile electronic communication device) to a first position P1, which provides a first state (e.g., “ON”), and a second direction (e.g., toward a rear surface of the mobile electronic communication device) opposite the first direction to a second position P2, which provides a second state (e.g., “OFF”).
In various embodiments, the switch 125 includes an actuator 125a configured to actuate the AV switch 12 (at least) between the first position P1 and the second position P2. The actuator 125a may be encompassed by a layer of flexible material 125b that protrudes outside of the protective case. In some embodiments, the layer of flexible material 125b forms a recess for receiving the actuator 125a. A user may interact with the a layer of flexible material 125b to move the actuator 125a. The switch 125 may be provided in an opening through the peripheral wall 120a of the front cover 120 to allow the actuator 125a to engage the AV switch 12 of the mobile electronic communication device when the mobile electronic communication device is received in the protective case 100. In some embodiments, the switch 125 may be formed with the peripheral wall 120a (e.g., the switch 125, or the layer of flexible material 125b, and the peripheral wall 120a may be formed by overmolding together). In further embodiments, the switch 125 may be formed with an undercut 126 for receiving the actuator 125a such that the layer of flexible material 125b encompasses the actuator 125a. In some embodiments, the actuator 125a snap fits or pushes into the undercut 126 of the switch 125. The actuator 125a may be formed separately from the remainder of the switch 125 and later affixed to the undercut 126 of the switch 125, or the actuator may be formed with the switch 125 as one piece. In some embodiments, the actuator 125 may be formed by injection molding. In further embodiments, the actuator 125 may be formed of any suitable material for engaging with the AV switch 12, such as, but not limited to, nylon, acrylonitrile butadiene styrene (ABS), and/or the like. Thus, the switch 125 may be slidably movable relative to the front cover 120 (or other suitable portion of the protective case 100) along an axis that is parallel to the dimension along which the AV switch moves. In other embodiments, the switch 125 may pivot or rotate along an axis that is orthogonal to the dimension along which the AV switch moves (e.g., a rocking switch), for actuating the AV switch. In particular embodiments, the actuator 125a may not extend beyond the outer edge of the peripheral wall 120a (e.g., the actuator 125a may extend out to before the outer edge or to the outer edge). In one embodiment, the peripheral wall 120a is a single overmolded layer that extends in a rectangular perimeter and provides cushioning to an encased mobile electronic communication device, while also sealing the openings corresponding to switches and buttons of the device (e.g., with the switch 125). In other embodiments, the peripheral wall 120a includes a plurality of discrete pieces melded together to form the wall 120a (e.g., a top portion of the wall 120a may be separately formed from a side portion of the wall 120a).
In some embodiments, the actuator 125a includes a first engagement surface 201 and a second engagement surface 203 that selectively engages the AV switch 12 as the switch 125 is moved. After engagement between the AV switch 12 and the first engagement surface 201 or the second engagement surface 203, further movement of the switch 125 causes the engaged surface 201, 203 of the actuator 125a to push or otherwise move the AV switch 12 in a corresponding direction.
Accordingly, in particular embodiments, the actuator 125a is configured such that the first engagement surface 201 causes the AV switch 12 to move in the second direction from the first state (e.g., “ON”, P1) to the second state (e.g., “OFF”, P2) when the switch 125 is shifted in the second direction. In addition, the actuator 125a is configured such that the second engagement surface 203 causes the AV switch 12 to move in the first direction from the second state (“P2”) to the first state (“P1”) when the switch 125 is shifted in the first direction.
In some embodiments, the switch 125 is configured to be movable in the first direction (at least) until the AV switch 12 reaches the first position P1, at which the AV switch 12 is in the first state (e.g., “ON”). In further embodiments, the switch 125 is configured to be movable in the second direction (at least) until the AV switch 12 reaches the second position P2, at which the AV switch 12 is in the second state (e.g., “OFF”).
In other embodiments, instead of shifting linearly, the switch 125 is configured to be statically maintained in the protective case 600 and to pivot upward and downward about an axis that is orthogonal to the dimension along which the AV switch shifts. In such embodiments, the actuator 125a is configured such that the first engagement surface 201 causes the AV switch 12 to move in the second direction from the first state (e.g., “ON”, P1) to the second state (e.g., “OFF”, P2) when the switch 125 is pivoted or rotated in a downward direction (e.g., rotated in a direction from P1 to P2). In addition, the actuator 125a may be configured such that the second engagement surface 203 causes the AV switch 12 to move in the first direction from the second state (“P2”) to the first state (“P1”) when the switch 125 is pivoted or rotated in an upward direction (e.g., rotated in a direction from P1 to P2).
In yet further embodiments, the switch 125 includes an indicator for indicating a position of the rotatable member 125, for example, relative to the first position P1 and the second position P2. One or more markers or indicators may be provided on the front cover 120 to indicate the location of the first position P1 and/or the second position P2. Accordingly, a user can readily determine the state of the AV switch 12 based on the indicators on the first cover 120. In further embodiments, the switch 125 includes a stop member for preventing continued movement of the switch 125 in the first direction and/or the second direction. Although various embodiments relate to a switch for actuating the AV switch 12, in other embodiments, any one or more of the other features of the protective case 100 may be a switch for actuating a corresponding operator of the mobile electronic communication device.
In some embodiments, the switch 125 includes curved portions 125c. The curved portions 125c may be concave shaped (when viewed from outside of the protective case 100), and may curve inwards towards the AV switch 12 or actuator 125a of the mobile electronic communication device. The curved portions 125c are suitably thin or flexible (or both) to allow the switch 125 to freely pivot, but rigid enough to provide structural integrity and support. The curved portions 125c can provide stability and support for maintaining the actuator 125a in a particular position or state (e.g., a neutral state at which the actuator 125a does not move or change the state of the AV switch 12) when the actuator 125a is not manually manipulated, while also enhancing the ability of a user to grip and manual manipulate the actuator 125a and providing a seal to inhibit passage of moisture into the protective case 100. According to various embodiments, the a layer of flexible material 125b and the curved portions 125c may be made of any suitable flexible, resilient material, such as, but not limited to, thermoplastic polyurethane, and/or the like.
FIG. 7A is a view of a front cover of another protective case 700 according to various embodiments. FIG. 7B is a cross-section view of a portion of the protective case 700 according to various embodiments. Features described with respect to embodiments of FIGS. 7A and 7B can be employed in other embodiments including, but not limited to, embodiments described with respect to FIGS. 1-6B. Same reference numbers as those previously illustrated and introduced may correspond to the depiction and description of those reference numbers previously illustrated and previously described.
Referring to FIGS. 7A and 7B, in some embodiments, the protective case 700 includes at least one switch 725 configured to allow actuation of one or more switches of the mobile electronic communication device while the mobile electronic communication device is encased in the protective case 700. For example, the switch 725 may be similar in function and structure to the switch 125. In other embodiments, the switch 725 may have any other suitable configuration. The protective case 700 may further include a front cover 720 having an outer peripheral wall 721a, which may be similar or correspond to the outer peripheral wall 121a. The switch 725 may include an actuator 725a, which may be similar or correspond to the actuator 125a, and curved portions 725c, which may be similar or correspond to curved portions 125c. The curved portions 725c are suitably thin or flexible (or both) to allow the switch 125 to freely pivot, but rigid enough to provide structural integrity and support as described above with respect to curved portions 725c. 
In some embodiments, the side of the protective case 700 on which the switch 725 is located has an outer peripheral wall 721a with an outer surface at a first level X. In particular embodiments, a recess of level Y from the outer surface level X is provided adjacent to the switch 725, toward the front and rear of the protective case 700, to improve manual access to the switch 725 from the front or rear of the protective case 700. With the switch 725 located within a recess from the outer surface X of the protective case, the switch 725 can be protected against accidental impact or actuation. In some embodiments, the actuator 725a may extend to a level not exceeding the second level Y. In other embodiments, the actuator 725a may extend to another level such as, by not limited to, a level not exceeding the first level X, or to a greater level. In some embodiments, a layer of flexible material 725b and the curved portions 725c may be formed by overmolding (e.g., over the inner surface of the outer peripheral body 721).
FIG. 8 is a cross-section view of a portion of a protective case 100 according to various embodiments. Features described with respect to the embodiment of FIG. 8 can be employed in other embodiments including, but not limited to, embodiments described with respect to FIGS. 1-7B. Same reference numbers as those previously illustrated and introduced may correspond to the depiction and description of those reference numbers previously illustrated and previously described.
Referring to FIG. 8, a cross-sectional view shows the aperture 118 in the front surface 140b of the membrane 140. The aperture 118 may be configured and located adjacent to (or otherwise in audio communication with) an audio device, such as, but not limited to, a speaker or a microphone of an encased mobile communication device, when the mobile communication device is located within the protective case 100. The aperture 118 may be covered or layered with the film 146. As discussed above, the membrane 140 may be a transparent membrane configured to allow a display screen of a mobile device to be seen through the membrane 140. The film 146 may be an audio vent, and may be attached to the membrane 140 in any suitable manner, such as, but not limited to, an adhesive tape, molding, glue, thermal bonding, or the like. In addition, the protective case 100 may further include a gasket 802 coupled to the film 146 and encircling the aperture 118. The gasket 802 may improve the acoustic quality of the sound emanating from the speaker of the mobile communication device by sealing and focusing the acoustics to the area encompassed by the gasket 802. In doing so, the gasket 804 may help prevent audio feedback and poor sound quality. In other embodiments, the gasket may be made from any other pliable material, such as, but not limited to, foam, liquid silicone rubber (LSR), microcellular urethane (e.g., PORON®), combinations thereof, and/or the like. In some embodiments, the gasket 802 is configured to contact a face of a mobile device when the mobile device is housing in the protective case 100. In other embodiments, the gasket 802 is configured to be spaced apart from the mobile device when the mobile device is housed in the protective case 100.
Accordingly, the protective case 100 may include a layered structure at the aperture 118 of the membrane 140. The layered structure may include the membrane 140 attached to the film 146, which is attached to the gasket 802. In other words, the layered structure at the aperture 118 includes the film 146 interposed between the membrane 140 and the gasket 802, such that the membrane 140 does not directly contact the gasket 802. In other embodiments, the film 118 is located over the membrane 140 (e.g., at the front surface 140b of the membrane 140), as opposed to being beneath the membrane 140 (e.g., at the rear surface 140a of the membrane 140). In such embodiments, the gasket 802 may be interposed between the membrane 140 and the film 148 over and above the membrane 140 (e.g., at the front surface 140b of the membrane 140). In some embodiments, the gasket 802 completely surrounds the aperture 118. In other embodiments, the gasket 802 partially surrounds the circumference of the aperture 118 (e.g., a first section of the gasket 802 is located along the top curve and a second section along the bottom curve of the aperture 118, with the two sections of the gasket 802 being unconnected). In some embodiments, the gasket 802 (fully or partially) encompasses the aperture 118 in an oval shape. In other embodiments, the gasket 802 encompasses the aperture 118 in any suitable shape, such as, but not limited to, a square shape, a diamond shape, or the like.
FIG. 9A is a perspective view of a portion of the protective case 100 according to various embodiments. FIG. 9B is a cross-section view of a portion of the protective case 100 according to various embodiments. FIG. 9C is a cross-section view of a portion of the protective case 100 according to various embodiments. Features described with respect to the embodiments of FIGS. 9A-9C can be employed in other embodiments including, but not limited to, embodiments described with respect to FIGS. 1-8. Same reference numbers as those previously illustrated and introduced may correspond to the depiction and description of those reference numbers previously illustrated and previously described.
Referring to FIGS. 9A, 9B, and 9C, the protective case 100 may further include a first bottom aperture 902 and a second bottom aperture 903. Each of the bottom apertures 902 and 903 may correspond to locations of a speaker or microphone of an encased mobile communication device for allowing sound to enter and/or exit the protective case 100.
Referring to FIG. 9B, a cross-sectional view focused on the first bottom aperture 902 is depicted. The protective case 100 at the first bottom aperture 902 includes a film 904 and a gasket structure 906. The film 904 may correspond to the film 146. The gasket structure 906 includes a first gasket 906a and a second gasket 906b. The first and second gaskets 906a and 906b may correspond to the gasket 802, discussed above. The gasket structure 906 separates the film 904 from the film 146. In some embodiments, the film 904 may be interposed between the first and second gaskets 906a and 906b of the gasket structure 906. The second gasket 906b of the gasket structure 906 is located proximate an encased mobile communication device and the first gasket 906a of the gasket structure 906 is located proximate the membrane 140. Accordingly, in some embodiments, the film 904 is completely sandwiched along its circumference between two rings formed by the first and second gaskets 906a and 906b. In other embodiments, the circumference of the film 904 is partially interposed between the two rings (e.g., portions of the circumference of the film 904 are not covered by the gasket structure 906). The top ring formed of the second gasket 906b may be attached to the membrane 140, and the bottom ring formed of the first gasket 906a, or a portion thereof, may be attached to structure on the inside of the protective case 100.
Accordingly, the protective case 100 may include a layered structure at the first bottom aperture 902 of the membrane 140. The layered structure may include the second gasket 906b attached to the membrane 140, a film 904 attached to the second gasket 906b, and the first gasket 906a attached to the film 904. In other words, the layered structure at the aperture 902 includes the film 904 interposed between the first gasket 906a and the second gasket 906b, such that the membrane 140 does not directly contact or directly attach to the film 904. The separation of the film 904 from the membrane 140 by the gasket structure 906, can inhibit communication of vibrations (audio or otherwise) between the membrane 140 and the film 904 and, thus, can improve audio quality of sound passing through the aperture 902 in the protective case 100.
In some embodiments, a small chamber 908 is located directly beneath the film 902. The small chamber 908 may be an open cavity within the protective case and may provide a pathway for sound originating from the encased mobile device to be transmitted to outside of the protective case 100, or for sound originating from outside the protective case 100 to propagate into the encased mobile device. The small chamber 908 may be define by having borders including the film 904, the inner wall of the protective case 100, and a mobile device when the mobile device is housed within the protective case 100.
