DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION
FIG. 1A illustrates a front view of a housing 100 for a portable electronic device. FIG. 1B illustrates a plan view of the housing 100. FIG. 1C illustrates a side view of the housing 100.
The portable electronic device may, for example, be a mobile telephone, a games console, a personal music player, a personal digital assistant or a tablet computer. The portable electronic device may be small enough to fit inside a user's pocket.
The housing 100 comprises a hollow, transparent shell 5 made from first and second half shells 6, 7. In the illustrated example, the first and second half shells 6, 7 are wholly made from a transparent, smooth material, such as glass or a transparent plastics material. Each half shell 6, 7 may be made from the same material. Each half shell 6, 7 is integrally formed.
The transparent shell 5 has a length L1, a width W1 and a depth D1. The length L1 is greater than the width W1 and the depth D1. The width W1 is smaller than the length L1 and greater than the depth D1. The transparent shell 5 is tubular in shape and defines an inner space for housing electronic components of the portable electronic device.
The first half shell 6 comprises a first transparent curved portion 15, a transparent front wall 16 and a second transparent curved portion 17. The first transparent curved portion 15, the front wall 16 and the second transparent curved portion 17 are integrally formed.
In the example illustrated in FIGS. 1A, 1B and 1C, there are no apertures in the first transparent curved portion 15, the transparent front wall 16 and the second transparent curved portion 17. For example, there is no aperture for a display and there are no apertures for keys.
The front wall 16 is positioned intermediate the first transparent curved portion 15 and the second transparent curved portion 17. The front wall 16 comprises an inner surface 18 and an outer surface 19. The outer surface 19 of the front wall 16 provides the front face 19 of the housing 100. In the illustrated example, at least a portion of the front face 19 is substantially flat.
The first transparent curved portion 15 is configured to curve from the front wall 16 to a first side wall 50 of the housing 100. The first transparent curved portion 15 has an outer surface 11 and an inner surface 12. The outer surface 11 of the first transparent curved portion 15 has a convex curvature and curves from the front face 19 to an outer surface 51 of the first side wall 50, in plane defined by the depth D1 and the width W1 of the transparent shell 5. The outer surface 51 of the first side wall 50 provides a first side face 51 of the housing 100. In this example, a portion of the first side wall 50 is provided by the first transparent half shell 6, and a portion is provided by the second transparent half shell 7.
The inner surface 12 of the first transparent curved portion 15 has a convex curvature and curves from the inner surface 18 of the front wall 16 to an inner surface 53 of the first side wall 50, in a plane defined by the depth D1 and the width W1 of the transparent shell 5.
The arc of curvature of both the outer surface 11 and the inner surface 12 of the first transparent curved portion 15 increases as the first transparent curved portion 15 extends from the front wall 16 to the first side wall 50. In the illustrated first example, the arc of curvature of the inner surface 12 of the first transparent curved portion 15 increases at a faster rate than the arc of curvature of the outer surface 11, which means that the thickness of the first transparent curved portion 15 increases as it extends from the front wall 16 to the first side wall 50. Consequently, the thickness r2 of the first side wall 50 is greater than the thickness r1 of the front wall 16.
The second transparent curved portion 17 is configured to curve from the front wall 16 to a second side wall 52 of the housing 100. An outer surface 58 of the second side wall 52 provides a second side face 58 of the housing 100. In this example, a portion of the second side wall 52 is provided by the first transparent half shell 6, and a portion is provided by the second transparent half shell 7.
The distance W1 between first side face 51 and the second side face 58 defines the width W1 of the housing 100. The arrow denoted with W2 in FIG. 1B indicates the distance between the inner surface 53 of the first side wall 50 and the inner surface 57 of the second side wall 52.
The second transparent curved portion 17 has an outer surface 13 and an inner surface 14. The outer surface 13 of the second transparent curved portion 17 has a convex curvature and curves from the front face 19 to the outer surface 58 of the second side wall 52, in a plane defined by the depth D1 and the width W1 of the transparent shell 5.
The inner surface 14 of the second transparent curved portion 17 has a convex curvature and curves from the inner surface 18 of the front wall 16 to the inner surface 57 of the second side wall 52 in a plane defined by the depth D1 and the width W1 of the transparent shell 5.
The arc of curvature of both the outer surface 13 and inner surface 14 of the second transparent curved portion 17 increases as the second transparent curved portion 17 extends from the front wall 16 to the second side wall 52. In the illustrated example, the arc of curvature of the inner surface 14 of the second transparent curved portion 17 increases at a faster rate than the arc of curvature of the outer surface 13, which means that the thickness of the second transparent curved portion 17 increases as it extends from the front wall 16 to the second side wall 52. Consequently, the thickness r2 of the second side wall 52 is greater than the thickness r1 of the front wall 16.
As can be seen from FIG. 1A, the front wall 16 extends along the whole of the length L1 of the transparent shell 5. The first transparent curved portion 15 and the second transparent curved portion 17 are curved walls which also extend along the whole of the length L1 of the transparent shell 5.
In the example illustrated in FIGS. 1A, 1B and 1C, the first transparent half shell 6 is joined to the second transparent half shell 7 at each of the side walls 50, 52. The reference numerals 54 and 56 indicate the discontinuities where the first transparent half shell 6 is attached to the second transparent half shell 7. In the example illustrated in FIGS. 1A, 1B and 1C, the discontinuities 54, 56 extend along the whole of the length of the transparent shell L1. The first transparent half shell 6 may, for example, be directly adhered to the second transparent half shell 7 at the discontinuities 54, 56.
The second half shell 7 comprises a third transparent curved portion 25, a transparent rear wall 26 and a fourth transparent curved portion 27. The third transparent curved portion 25, the transparent rear face 26 and the fourth transparent curved portion 27 are integrally formed.
In the example illustrated in FIGS. 1A, 1B and 1C, there are no apertures in the third transparent curved portion 25, the transparent rear wall 26 and the fourth transparent curved portion 27. For example, there is no aperture for a camera.
The rear wall 26 is positioned intermediate the third transparent curved portion 25 and the fourth transparent curved portion 27. An outer surface 29 of the rear wall 26 provides the rear face of the housing 100. In the illustrated example, at least a portion of the rear face 29 is substantially flat. The rear wall 26 has an inner surface 28 and a thickness r1. In this example, the rear wall 26 has the same thickness r1 as the front wall 16.
The distance D1 between the rear face 29 and the front face 19 defines the depth D1 of the housing 100. The arrow denoted D2 indicates the distance between the inner surface 18 of the front wall 16 and the inner surface 28 of the rear wall 26.
The third transparent curved portion 25 is configured to curve from the rear wall 26 to the first side wall 50 of the housing 100. The third transparent curved portion 25 has an outer surface 21 and an inner surface 22. The outer surface 21 of the third transparent curved portion 25 has a convex curvature and curves from the rear face 29 to the first side face 51, in a plane defined by the depth D1 and the width W1 of the transparent shell 5. The inner surface 22 of the third transparent curved portion 25 has a convex curvature and curves from the inner surface 28 of the rear wall 26 to the inner surface 53 of the first side wall 50, in a plane defined by the depth D1 and the width W1 of the transparent shell 5.
The arc of curvature of both the outer surface 21 and the inner surface 22 of the third transparent curved portion 25 increases as the third transparent curved portion 25 extends from the rear wall 26 to the first side wall 50. In the illustrated first example, the arc of curvature of the inner surface 22 of the third transparent curved portion 25 increases at a faster rate than the arc of curvature of the outer surface 21, which means that the thickness of the third transparent curved portion 22 increases as it extends from the rear wall 26 to the first side wall 50. Consequently, the thickness r2 of the first side face 50 is greater than the thickness r1 of the rear face 26.
The fourth transparent curved portion 27 is configured to curve from the rear wall 26 to the second side wall 52 of the housing 100. The fourth transparent curved portion 27 has an outer surface 23 and an inner surface 24. The outer surface 23 of the fourth transparent curved portion 27 has a convex curvature and curves from the rear face 26 to the second side face 58, in a plane defined by the depth D1 and the width W1 of the transparent shell 5. The inner surface 24 of the fourth transparent curved portion 27 has a convex curvature and curves from the inner surface 28 of the rear wall 26 to the inner surface 57 of the second side wall 52, in a plane defined by the depth D1 and the width W1 of the transparent shell 5.
The arc of curvature of both the outer surface 23 and the inner surface 14 of the fourth transparent curved portion 27 increases as the fourth transparent curved portion 27 extends from the rear face 26 to the second side face 52. In the illustrated example, the arc of curvature of the inner surface 24 of the fourth transparent curved portion 27 increases at a faster rate than the arc of curvature of the outer surface 23, which means that the thickness of the fourth transparent curved portion 27 increases as it extends from the rear wall 26 to the second side wall 52. Consequently, the thickness r2 of the second side face 52 is greater than the thickness r1 of the front face 16.
The rear wall 26 extends along the whole of the length L1 of the transparent shell 5. The third transparent curved portion 25 and the fourth transparent curved portion 27 are curved walls which also extend along the whole of the length L1 of the transparent shell 5.
It can be seen from FIG. 1B that, in this example, the first transparent curved portion 15 is symmetrical with the second transparent curved portion 17 and the third transparent curved portion 25. The second transparent curved portion 17 is symmetrical with the fourth transparent curved portion 27. The third transparent curved portion 25 is symmetrical with the fourth transparent curved portion 27.
In the example illustrated in FIGS. 1A, 1B and 1C the transparent shell 5 is tubular in shape and includes first and second openings 40, 42 at each end of the length L1 of the transparent shell 5.
The first opening 40, positioned at an upper end of the length of the transparent shell 5, is defined by a first outer rim 30, 32 of the first and second half shells 6, 7. A portion 30 of the circumference of the first outer rim is provided by the first transparent curved portion 15, the front wall 16 and the second transparent curved portion 17. A further portion 32 of the circumference of the first outer rim is provided by the third transparent curved portion 25, the rear wall 26 and the fourth transparent curved portion 27.
The first outer rim 30, 32 is substantially perpendicular to the length L1 of the transparent shell 5. The first outer rim 30, 32 comprises a recess 8 at the front wall 16.
The second opening 40, positioned at a lower end of the length of the transparent shell 5, is defined by a second outer rim 34, 36 of the first and second half shells 6, 7. A portion 34 of the circumference of the second outer rim is provided by the first transparent curved portion 15, the front wall 16 and the second transparent curved portion 17. A further portion 36 of the circumference of the second outer rim is provided by the third transparent curved portion 25, the rear wall 26 and the fourth transparent curved portion 27.
The second outer rim 34, 36 is substantially perpendicular to the length L1 of the transparent shell 5. The second outer rim 34, 36 comprises a recess 9 at the front wall 16.
FIG. 2 illustrates a first end cap 70 and a second end cap 75. The first end cap 70 comprises a first, upper, portion 72 and a second, lower, portion 74. The second portion 74 is shaped for insertion into the first opening 40 and is configured to hold the first end cap 70 in place. In this regard, the second portion 74 has a width W2 substantially corresponding with the distance between the inner surfaces 53, 57 of the two side walls 50, 52 of the transparent shell 5 and a depth D2 substantially corresponding with the distance between the inner surfaces 18, 28 of the front wall 16 and the rear wall 26 (see FIG. 1B). The second portion 74 is dimensioned to enable a push-fit connection to be provided between the lower portion 74 of the first end cap 70 and the inner surfaces 12, 14, 18, 22, 24, 28 of the transparent shell 5. Friction prevents the lower portion 74 of the first end cap 70 from falling out of the first opening 40 once it has been inserted.
The first portion 72 of the first end cap 70 is shaped to cover the first outer rim 30, 32 of the transparent shell 5 and the first opening 40. In this regard, the first portion 72 has a width W1 substantially corresponding with the distance between the two side faces 51, 58 of the transparent shell 5 and a depth D1 substantially corresponding with the distance between the front face 19 and the rear face 29 (see FIG. 1B).
The first end cap 70 is configured to house an audio device, such as a loudspeaker/earpiece. The first end cap 70 further comprises a third portion 72 that protrudes outwardly, in the depth direction, from the second portion 74. The third portion 72 is shaped to fit into the recess 8 in the first outer rim 30, 32 of the first transparent half shell 6. The third portion 72 comprises an aperture 71 for the audio device housed in the first end cap 70. For example, if the audio device is a loudspeaker, the aperture enables sound waves produced by the loudspeaker to exit the first end cap 70.
The second end cap 75 comprises a first, upper, portion 78 and a second, lower, portion 76. The first portion 78 is shaped for insertion into the second opening 42 and is configured to hold the second end cap 75 in place. In this regard, the first portion 78 has a width W2 substantially corresponding with the distance between the inner surfaces 53, 57 of the two side walls 50, 52 of the transparent shell 5 and a depth D2 substantially corresponding with the distance between the inner surfaces 18, 28 of the front wall 16 and the rear wall 26 (see FIG. 1B). The first portion 78 is dimensioned to enable a push-fit connection to be provided between the upper portion 78 of the second end cap 75 and the inner surfaces 12, 14, 18, 22, 24, 28, 53, 57 of the transparent shell 5. Friction prevents the upper portion 78 of the second end cap 75 from falling out of the second opening 42 once it has been inserted.
The second portion 76 of the second end cap 75 is shaped to cover the second outer rim 34, 36 of the transparent shell 5 and the second opening 42. In this regard, the second portion 76 has a width W1 substantially corresponding with the distance between the two side faces 51, 58 of the transparent shell 5 and a depth D1 substantially corresponding with the distance between the front face 19 and the rear face 29 (see FIG. 1B).
The second end cap 75 is configured to house an audio device, such as a microphone. The second end cap 75 further comprises a third portion 78 that protrudes outwardly, in the depth direction, from the first portion 78. The third portion 78 is shaped to fit into the recess 9 in the second outer rim 34, 36 of the first transparent half shell 6. The third portion 78 comprises an aperture 77 for the audio device housed in the second end cap 75. For example, if the audio device is a microphone, the aperture enables sound waves produced by a user to reach the diaphragm of the microphone.
FIG. 3 illustrates the housing 100 with the first and second end caps 70, 75 in position. The housing 100 illustrated in FIG. 3 has a length L2 which is a little longer than the length of the transparent shell L1.
It can be seen from FIG. 3 that, in this exemplary embodiment of the invention, the only apertures in the housing 100 are those in the first and second end caps 70, 75. The presence of the apertures 71, 77 in the end caps 70, 75 for a loudspeaker and a microphone means that it is not necessary for such apertures to be present in the transparent shell 5. An advantageous technical effect of this is that the transparent shell 5 is stronger than it would be if such apertures were present in the transparent shell 5.
It can also be seen from FIG. 3 that the first and second end caps 70, 75 are positioned to cover the first and second outer rims 30, 32, 34, 36 of the transparent shell 5. A technical effect of the first and second end caps 70, 75 and their positioning is that they protect the first and second outer rims 30, 32, 34, 36 from being damaged in the event that the housing 100 is dropped. This is particularly advantageous if the transparent shell 5 is made from a brittle material, such as glass.
FIG. 4 illustrates a portable electronic device 200 comprising the housing 100 illustrated in FIGS. 1A to 3. In this particular example, the portable electronic device 200 comprises a curved display 210. The transparency of the curved transparent portions 15, 17 of the housing 100 enables a curved display 210 to be provided.
The curved display 210 may, for example, be an organic light emitting diode (OLED) display. The curved display 210 may be a touch sensitive display. The display 210 may, for example, operate using capacitive technology. The curved display 210 comprises a first curved portion 215, a substantially flat portion 216 and a second curved portion 217.
The first curved portion 215 of the display 210 is configured to curve in register with the first transparent curved portion 15 of the transparent shell 5. For example, the curvature of the first curved portion 215 may follow the curvature of the inner surface 12 of the first transparent curved portion 15 of the transparent shell 5.
The second curved portion 217 of the display 210 is configured to curve in register with the second transparent curved portion 17 of the transparent shell 5. For example, the curvature of the second curved portion 217 may follow the curvature of the inner surface 14 of the second transparent curved portion 17 of the transparent shell 5.
In the example illustrated in FIG. 4, the curved display 210 extends across the first transparent portion 15, the front wall 16 and the second transparent curved portion 17. It terminates at the discontinuities 54, 56, at the side walls 50, 62 of the housing 100.
In some alternative embodiments of the invention, at least some of the display 210 may extend across the side walls 50, 52 and the third and fourth transparent curved portions 25, 27 of the transparent shell 5. For example, at least some of the display 210 may curve in register with the third and fourth transparent curved portions 25, 27. It may be that the display 210 extends around the whole circumference of the transparent shell 5, including the rear wall 26.
It will be appreciated by those skilled in the art, however, that embodiments of the invention are not restricted to the use of a curved display 210 such as that illustrated in FIG. 4. Instead, a flat display may be provided.
Since the shell 5 of the housing 100 is transparent, it is not necessary to have an aperture for the display 210. The display 210 is viewable through the transparent shell 5. An advantageous technical effect of not having such an aperture is that the housing 100 is stronger than it would be if such an aperture were present.
FIG. 5 illustrates a rear view of the portable electronic device 200. In the illustrated example, the portable electronic device 200 comprises a camera 90. The portable electronic device 200 may also comprise flash circuitry. The transparent shell 5 does not comprise an aperture for the camera. Images may be captured through the transparent rear face 26 of the shell 5. Also, the flash circuitry may provide light directly through the transparent shell 5.
In some alternative embodiments of the invention, one or both of the camera 90 and the flash circuitry may be housed in one of the end caps 70, 75. In these embodiments, an end cap 70, 75 may comprise one or more apertures for the camera 90 and/or the flash circuitry.
FIG. 6 illustrates an exploded view of an exemplary portable electronic device 200 according to embodiments of the invention. FIG. 6 illustrates one example of how such a portable electronic device 200 may be constructed.
In the FIG. 6 example, the portable electronic device 200 comprises a first transparent half shell 6. A flat, borderless, touch sensitive display 210 is positioned directly beneath the first transparent half shell 6. The display 210 is fixed to a display support plate 91 which may, for example, be made from metal.
An upper printed wiring board 92 is electrically connected to a lower printed wiring board 94 by a connector 93. In this example, the upper printed wiring board 92 is located in the first end cap 70 and comprises an earpiece/loudspeaker, an integrated handsfree, and a micro Universal Serial Bus (USB) chipset.
A battery 96 is adhered to the lower printed wiring board 94 using adhesive 95. The battery 96 sits, at least partially, in an antenna carrier 97 which comprises one or more antennas. The antenna carrier 7 is positioned adjacent to the transparent second half shell 7. In this example, a printed member may be present between the antenna carrier 97 and the second half shell 7 to prevent the antenna carrier 97 and/or the battery 96 from being visible to the user.
FIG. 7 illustrates an alternative embodiment of the transparent shell 151 which comprises only one opening 42 at the lower end of the shell 151. In this example, there is no opening at the upper end of the shell 151. In some further alternative embodiments of the invention, the opening 42 may not be present and the transparent shell 5 may be ‘closed’.
Although embodiments of the present invention have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the invention as claimed. For example, the front face 19 and the rear face 29 are illustrated in the figures as being substantially flat. However, in some embodiments of the invention, at least a portion of the front face 19 and/or the rear face 29 may be curved. The side faces 51, 58 are illustrated in the figures as being curved, but in alternative embodiments of the invention they may be substantially flat or include substantially flat portions.
The transparent shell 5 is described above as being made up of two half shells 6, 7 that are joined together. In some alternative embodiments of the invention, the transparent shell 5 may be integrally formed, such that the discontinuities 54, 56 are not present.
Features described in the preceding description may be used in combinations other than the combinations explicitly described.
Although functions have been described with reference to certain features, those functions may be performable by other features whether described or not.
Although features have been described with reference to certain embodiments, those features may also be present in other embodiments whether described or not.
Whilst endeavoring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
