     BACKGROUND 
     This relates generally to electronic devices and, more particularly, to electromagnetic shielding structures for electronic devices. 
     Electronic devices such as cellular telephones and computers often contain circuitry that is sensitive to electromagnetic interference. For example, electronic devices often contain wireless transceiver circuitry that contains receiver circuits that are susceptible to radio-frequency interference. Radio-frequency interference can be generated by circuits on a logic board that is mounted within an electronic device housing. 
     During operation, radio-frequency interference signals may escape from within the electronic device housing. Signals that have escaped from within the device may be picked up by antenna structures and may cause interference to sensitive receiver circuitry that is coupled to the antenna structures. Metal housing structures with openings may sometimes exacerbate interference problems, because the openings may have sizes that give rise to undesired signal resonances. 
     It would therefore be desirable to be able to provide improved ways in which to reduce electromagnetic signal interference in electronic devices. 
     SUMMARY 
     An electronic device such as a computer may have a conductive housing. The conductive housing may be formed from aluminum or other metals. Openings may be formed in the conductive housing. The openings may be used to accommodate keyboard keys or other components. 
     To prevent signal interference, a conductive shielding layer may be used to cover the undersides of the openings and the components associated with the openings. The conductive shielding layer may be formed from a polymer layer coated with a layer of reflective metal. The conductive shielding layer may serve as a reflector for a light guide plate that is used to distribute backlight to keyboard keys in a keyboard. The conductive shielding layer may have a rectangular shape with a rectangular periphery. The conductive shielding layer may be connected to the conductive housing conductive adhesive around the rectangular periphery. 
     The electronic device may include a keyboard having buttons and a conductive support structure. The support structure may include openings through which light passes to reach the keyboard keys. The openings of the support structure may include bridging paths that help to block electromagnetic interference. The support structure may be electrically connected to an interior surface of the conductive housing along the periphery of the keyboard. 
     Further features of the invention, its nature and various advantages will be more apparent from the accompanying drawings and the following detailed description of the preferred embodiments.

     DETAILED DESCRIPTION 
     An illustrative electronic device of the type that may be provided with electromagnetic shielding is shown in  FIG. 1 . Electronic devices such as device  10  of  FIG. 1  may be cellular telephones, media players, other handheld portable devices, somewhat smaller portable devices such as wrist-watch devices, pendant devices, or other wearable or miniature devices, gaming equipment, tablet computers, notebook computers, desktop computers, televisions, computer monitors, computers integrated into computer displays, or other electronic equipment. In the example of  FIG. 1 , device  10  is a portable electronic device such as a notebook computer, cellular telephone, media player, or other portable electronic devices (e.g., handheld electronic devices). This is merely an illustrative example. Electronic device  10  may, in general, be based on any suitable electronic equipment. 
     As shown in the example of  FIG. 1 , device  10  may include a display such as display  14 . Display  14  may be mounted in a housing such as housing  12 . Housing  12  may have an upper portion such as portion  12 A and a lower portion such as portion  12 B. Display  14  may be mounted in portion  12 A, so portion  12 A may sometimes be referred to as a display housing or lid. Portion  12 B may sometimes be referred to as a base housing or keyboard housing. 
     Housing lid  12 A may be joined with base housing  12 B using hinge structures that lie along rotational axis  16 . The hinge structures may allow housing lid  12 A to rotate relative to base housing  12 B about rotational axis  16 . The hinge structures may be mounted in a portion of housing  12  such as clutch barrel  24 . Clutch barrel  24  may also contain antenna structures. If care is not taken, radio-frequency signals that are produced by the internal components in device  10  may escape through openings in housing  12 B and may be received as interference by the antenna structures in clutch barrel  24  and associated sensitive wireless receiver circuitry in device  10 . 
     As shown in  FIG. 1 , device  10  may have components such as keyboard  18  and track pad  22 . Keyboard  18  may include an array of keys  20  (e.g., a two dimensional array). Housing  12 B may have openings that are configured to receive keys  20 . 
     Housing  12 , which may sometimes be referred to as an enclosure or case, may be formed of plastic, glass, ceramics, fiber composites, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. Configurations in which housing  12  (e.g., housing  12 B and/or housing  12 A) is formed from a metal such as aluminum are sometimes described herein as an example. Housing  12  may be formed using a unibody configuration in which some or all of housing  12  is machined or molded as a single structure or may be formed using multiple structures (e.g., an internal frame structure, one or more structures that form exterior housing surfaces, etc.). 
     Housing  12  may have openings to accommodate components. As an example, housing  12 B may have openings to accommodate keyboard keys.  FIG. 2  is a perspective view of a portion of keyboard  18 , showing how keys  20  may be received in openings  26  in housing  12 B. Openings  26  have the potential to serve as pathways for electromagnetic interference signals. For example, circuitry that is mounted within the interior of device  10  has the potential to produce radio-frequency signals that can escape device  10  through openings  26 . 
     As shown in  FIG. 3 , openings such as opening  26  may be characterized by lateral dimensions such as dimension D. In some situations, dimension D may have a magnitude that causes opening  26  to resonate and produce undesired interference (e.g., opening  26  may operate as a slot-type antenna resonating element). Emitted radio-frequency interference signals may be received by antenna structures in clutch barrel  24  and associated sensitive receiver circuitry. Other sensitive components in device  10  (e.g., communications circuits, display components, etc.) also have the potential to be adversely affected by radio-frequency interference passing through openings  26 . 
     Electromagnetic signal shielding may be provided within housing  12 B to reduce interference.  FIG. 4  is a cross-sectional side view of base housing  12 B in device  10 . As shown in  FIG. 4 , device  10  may contain printed circuits such as printed circuit  30 . Printed circuit  30  may be a rigid printed circuit board (e.g., a fiberglass-filled epoxy board) or may be a flexible printed circuit (e.g., a layer of polyimide or a sheet of other flexible polymer). Components  32  may be mounted on substrate  30 . Components  32  may include integrated circuits such as processors, display driver integrated circuits, display timing chips, clocks, communications circuitry, graphics chips, and other circuits that have the potential to generate radio-frequency interference. 
     Keyboard  18  may be formed from key structures  20  that pass through openings  26 . Keyboard structures  34  may include structures such as a metal support structure (sometimes referred to as a feature plate) that receives scissor springs for supporting keys  20 , a polymer sheet that contains dome switches or other switches for keys  20 , and a backlight unit for providing keyboard  18  with backlight. 
     To prevent interference from components  32  from reaching keyboard  18  and potentially passing through openings  26 , an electromagnetic shielding structure such as shielding structure  28  may be interposed between the circuitry of components  32  and the circuitry of keyboard  18 . Shielding structure  28  may be electrically shorted to housing  12  using electrical connections  36  (e.g., conductive adhesive, welds, solder, connectors, etc.). 
       FIG. 5  is a cross-sectional side view of some of the internal structures associated with keyboard  18 . As shown in  FIG. 5 , keyboard  18  may include switches such as dome switch  38 . During operation of keyboard  18 , a user may press key (key member)  20  downward in direction  52  to close switch  38 . Control circuitry in keyboard  18  may be used to detect the operation of key  20 . 
     Dome switch  30  may be mounted on a substrate such as substrate  50 . Substrate  50  may be a dielectric layer such as a layer of polyester. Conductive traces (e.g., patterned metal lines) may be formed on substrate  50  to route keyboard signals to control circuitry in device  10  (e.g., control circuitry such as circuits  32  on board  30  of  FIG. 4 ). Metal support structure  48  may be formed from a sheet of stainless steel, aluminum, or other metal. Support structure  48  (which may sometimes be referred to as a feature plate) may contain metal structures for supporting scissor springs associated with keys  20 . Openings may be formed in support structures  48  such as opening  54 . Feature plate openings  54  may be aligned with housing openings  26  and may be used to accommodate keyboard keys such as key member  20  of  FIG. 5 . 
     A backlight unit may be used to provide backlight for keyboard  18 . The backlight unit may include a light source such as light source  42  and a light guide plate such as light guide plate  40 . Light source  42  may be formed from one or more light-emitting diodes (as an example). Light guide plate  40  may be formed from a layer of clear plastic or other suitable material. During operation, light-emitting diodes  42  may emit light  44 . Light  44  may be coupled into edge  56  of light guide plate  40 . Due to the principal of total internal reflection, light guide plate  40  may distribute light  44  in lateral dimensions X and Y. Light  46  that is scattered upwards in direction  58  parallel to dimension Z may serve as backlight for keyboard  18 . Light that is scattered downwards from light guide plate  40  in direction  52  may be reflected back upwards in direction  58  by reflector  28 , thereby improving backlight efficiency. 
     Reflector  28  may serve as an electromagnetic shield that helps prevent radio-frequency interference signals from passing through openings  54  and  26  ( FIG. 2 ). As shown in  FIG. 5 , reflector  28  may have a dielectric layer such as layer  28 - 1  and a metal layer (or other conductive layer) such as metal layer  28 - 2 . Dielectric layer  28 - 1  may be formed from a material such as polyester or other flexible polymer. 
     Dielectric layer  28 - 1  may be a layer of polyester that is laminated to metal layer  28 - 2  (e.g., an aluminum layer, copper layer, or other metal layer). This example is merely illustrative. If desired, dielectric layer  28 - 1  and conductive layer  28 - 2  may be attached via any desired techniques. For example, conductive layer  28 - 2  may be a layer of metal deposited using deposition techniques such as chemical or physical deposition techniques. 
       FIG. 6  is a cross-sectional side view of a portion of keyboard  18  showing how the components of  FIG. 5  may be mounted within base housing  12 B. As shown in  FIG. 6 , keyboard key member  20  may be mounted to support structures  48  using scissor mechanism  60 . Reflector  28  may be shorted to housing  12 B using electrical connection  36 . In configurations in which housing  12 B is formed from a conductive material such as aluminum, it may be desirable to form an oxide coating on housing  12 B (e.g., by anodizing the surface of housing  12 B to form an anodized coating). To facilitate the formation of a satisfactory electrical connection between metal layer  28 - 2  of layer  28  the oxide coating may be laser etched or otherwise removed from region  62  of housing  12 B. Electrical connection  36  (e.g., a layer of conductive adhesive such as a conductive film or paste) may be used to form an electrical connection between housing  12 B and metal shielding layer  28 - 2  of reflector  28 . 
       FIG. 7  is a cross-sectional side view of a portion of device  10  in the vicinity of housing  12 B showing how substrate  50  may have a portion such as tail portion  50 T. Keyboard key switch structures such as dome switch  38  of  FIG. 5  may be mounted to substrate  50  in main portion  66  of substrate  50 . Main portion  66  of substrate  50  may be covered by shielding structure (reflector)  28 . Metal layer  28 - 2  in shielding structure  28  may provide electromagnetic shielding for main portion  66  of substrate  50 . Tail portion  50 T may be an integral portion of substrate  50  that extends from under shield structure  28  via shield structure opening  64 . Tail portion  50 T may be connected to printed circuit board  30 . Tail portion  50 T may have a bend of e.g., 90 degrees, 180 degrees, or other suitable angles. Conductive adhesive  36  or other electrically conductive material may be used in forming a seal around tail portion  50 T, thereby minimizing the area of the non-conductive portion of opening  64  and minimizing radio-frequency signal leakage out of the shielded area under shielding structure  28 . Material  36  may, for example, include a first layer that is interposed between ground traces on substrate  50  and metal layer  28 - 2  and a second layer that is interposed between ground traces on substrate  50  and conductive housing  12 B. 
       FIG. 8  shows how tail portion  50 T of substrate  50  may protrude from under shielding structure  28  through opening  64  between shielding structure  28  and the inner surface of housing  12 B. 
     Shielding structure  28  may be formed having a substantially rectangular structure.  FIG. 9  is an illustrative diagram of a rectangular shielding structure  28  that may help prevent electromagnetic interference from radiating through holes in housing  12 B (e.g., holes  26 ). Shielding structure  28  may surround keyboard  18 . Shielding structure  28  may be coupled to an interior (inner) surface of housing  12 B along the periphery of the rectangular area occupied by shielding structure  28 . For example, shielding structure  28  may be coupled to housing  12 B at one or more edges of structure  28  via conductive adhesive, solder, welds, etc. 
     The example of  FIG. 9  in which shielding structure  28  is substantially rectangular is merely illustrative. If desired, shielding structure  28  may be formed having any desired shape. For example, shielding structure  28  may be substantially square, trapezoidal, triangular, etc. Shielding structure  28  may, if desired, be formed having a shape corresponding to the shape of keyboard  18 . 
     If desired, keyboard support structures may be used to form shielding structures.  FIG. 10A  is an illustrative diagram in which conductive support structure (e.g., a metal support structure) may be used as a shielding structure. Conductive support structure  48  may include openings  54  (e.g., openings used to accommodate keyboard keys and/or button mechanisms). Openings  54  may be bridged using conductive paths such as path  102 . 
     Path  102  may be formed as an integral part of support structure  48 . For example, path  102  may be formed as part of a pattern used during a metal stamping process. Path  102  may serve to partition opening  54  into smaller openings while accommodating button mechanisms. Opening  54  having a bridging path  102  may be characterized by dimension D 1 . Dimension D 1  may correspond to the largest partition formed via bridging path  102 . Dimension D 1  may be sufficiently small to help prevent radio-frequency interference generated by components from reaching antennas or sensitive communications circuitry. For example, dimension D 1  may be sufficiently small in comparison to the wavelength of radio-frequency signals generated by components on device  10  so that the radio-frequency signals tend to be blocked by conductive support structure  48 . 
     If desired, opening  54  may be bridged by multiple paths.  FIG. 10B  is an illustrative example showing how opening  54  of support structure  48  may be bridged by multiple paths  102 . Opening  54  of  FIG. 10B  may be characterized by dimensions D 2 , D 3 , and D 4  that are sufficiently small so that support structure  48  blocks radio-frequency interference from components on device  10 . 
     The examples of  FIGS. 10A and 10B  in which bridging paths  102  are formed from vertical ( FIG. 10A ) and horizontal ( FIG. 10B ) conductive paths are merely illustrative. If desired, bridging paths  102  may be formed from paths having any desired shape. For example, paths  102  may be formed having one or more bends (e.g., 45 degree bends, 90 degree bends, or more). If desired, paths  102  may be formed having different widths. A given path may vary in width or shape along that path. 
       FIG. 11  is an illustrative cross-sectional diagram of a conductive support structure  48  that may serve as a shielding structure. As shown in  FIG. 11 , conductive support structure  48  may include bridging paths  102  that help to reduce the dimensions of opening  54  while ensuring that sufficient backlight  46  reaches button  20 . Conductive support structure  48  having bridging paths  102  may sometimes be referred to herein as a shielding support structure, because structure  48  tends to block radio-frequency signals while providing support for substrate  50  and button mechanisms such as scissor mechanism  60 . 
       FIG. 12  is an illustrative cross-sectional diagram showing how a shielding support structure  48  may be electrically coupled to an interior surface of housing  12 B (e.g., so that shielding support structure  48  is grounded to housing  12 B). As shown in  FIG. 12 , shielding support structure  48  may be coupled to region  112  of support structure  48  via electrical connections  114  (e.g., conductive adhesive, welds, solder, connectors, etc.). Shielding support structure  48  may be coupled to region  112  using electrical connections  114  using techniques similar to those used to electrically couple shielding structure  28  of  FIG. 6  to region  62  of housing  12 B (e.g., by removing an oxide coating from region  112 ). Shielding support layer  48  may be electrically coupled to regions  112  along the periphery of display  18 . If desired, shielding support layer  48  may be electrically coupled to housing  12 B at any desired location such as location  116 . 
     The foregoing is merely illustrative of the principles of this invention and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention. The foregoing embodiments may be implemented individually or in any combination.
