- the keyboard assembly 70 may be regarded as a component of the dome assembly 50 and includes a substrate 71, spacers 72 and a dome-overlaying laminate 73.
- the substrate 71 is a generally planar or substantially flat surface on which the dome-shaped element 60 is operably disposed.
- the substrate 71 may be, but is not required to be, provided as a printed circuit board (PCB) or as a flexible print circuit (FPC). Where an FPC is employed, the keyboard assembly 70 may further include a stiffening layer 74.
- the spacers 72 are disposed on the substrate 71 to at least partially surround the dome-shaped element 60.
- the laminate 73 may be include a layer of soft Polyethylene terephthalate (PET) film and is supported on at least the spacers 72 such that the laminate 73 is disposed at a distance from the substrate 71. This distance may be substantially similar to the height of the spacers 72. Adhesive may be provided on either side of the spacers 72 to improve adherence between the spacers 72 and the substrate 71 and between the spacers 72 and the laminate 73.
- PET Polyethylene terephthalate
- height of the spacers 72 may be lower than the height of the dome-shaped element 60. In such cases, once the keyboard assembly 70 is formed, the spacers 72 effectively pull the laminate 73 down toward the substrate 71 and over the dome-shaped element 60.
- the dome-shaped element 60 is operably interposed between the substrate 71 and the laminate 73 and includes a convex surface 61 that faces the laminate 73 and a concave surface 62 opposite the convex surface 61.
- the concave surface 62 originates at a center portion 63 of the dome-shaped element 60 and terminates at a periphery (or peripheral portion) 64 of the dome-shaped element 60.
- the concave surface 62 includes an annular array of spring-like or elastic elements 65 that extend from the center portion 63 to the periphery 64.
- at least one or more of the elastic elements 65 includes at least a first portion 66 and a second portion 67.
- the first portion 66 has a first slope S1 and is proximate to the center portion 63.
- the second portion 67 has a second slope S2 and is proximate to the periphery 64.
- each elastic element 65 may be similarly shaped and separated from adjacent elastic elements 65 by uniform distances. However, it is to be understood that this is not required and that more or less elastic elements 65 may be provided.
- the annular array of the elastic elements 65 is illustrated as being substantially balanced and uniformly arranged about the center portion 63, it is to be understood that this is not necessary and that the elastic elements 65 need not be balanced or uniformly arranged about the center portion 63.
- first contact pads 710 and second contact pads 711 which are respectively associated with one or more circuits of the electronic device 4 of FIGS. 1 and 2 , may be disposed on the substrate 71.
- the periphery 64 of the dome-shaped element 60 may be disposed in contact with, for example, the first contact pads 710 and the center portion 63 may be disposed at a distance from the second contact pad 711. That is, in accordance with embodiments, the center portion 63 and the concave surface 62 as a whole is centered at the second contact pad 711.
- the concave surface 62 may be at least partially formed of a conductive material, such as metal or a metallic alloy, and is formed to be deflectable as shown in FIG. 5 between an un-deflected position 610, an intermediately deflected position and a deflected position 612.
- the concave surface 62 is biased to remain in the un-deflected position 610 (see FIG. 5 ).
- the concave surface 62 is deflectable, as noted above, from the un-deflected position 610 in response to a pressing force being applied by a user or some other externality to the center portion 63 in a direction leading to the second contact pad 711. This pressing force causes the concave surface 62 to deflect toward and to eventually assume the deflected position 612 (see FIG. 5 ).
- the center portion 63 may be disposed in contact with the second contact pad 711 while the periphery 64 remains in contact with the first contact pads 710.
- the conductive material of the concave surface 62 may be configured to complete the one or more circuits of the electronic device 4 to thereby affect an operation of the electronic device 4.
- the one or more circuits of the electronic device 4 may be open with the concave surface 62 remaining disposed at or returning to the un-deflected position (i.e., default) 610 in accordance with the bias provided by the elastic elements 65.
- At least a portion 630 of the center portion 63 may be planar or substantially flat such that the portion 630 can abut and lie flush against the laminate 73. In some cases, the portion 630 may be adhered to the laminate 73 as well. The laminate 73 and the portion 630 may also be substantially parallel with the substrate 71.
- the first slope S1 and the second slope S2 may be defined with respect to the slope (or lack thereof) of the center portion 63. In addition, the second slope S2 may be greater than or exceed the first slope S1. It is to be understood, however, that the entirety of the center portion 63 need not be planar or substantially flat and may include various type of surface features.
- Such surface features may include, for example, depressions 631, micro-half cuts, dimples, etc., in the convex surface 61 that can be used to identify for a user where the center portion 63 is located and to improve the tactile feel of the dome assembly 50 as a whole or to collect dust.
- the concave surface 62 may have a wagon-wheel shape with the center portion 63 acting as a hub, the elastic elements 65 acting as spokes and the periphery 64 acting as the tire.
- the elastic elements 65 may all have similar shapes. That is, at least one of the first portions 66 may have substantially similar dimensions as another of the first portions 66 and at least one of the second portions 67 may have substantially similar dimensions as another of the second portions 67.
- the center portion 63 deforms linearly during a ramp-up stage with the linear deformation aided by the tapering of the at least one of the first portions 66. That is, the tapering of the at least one of the first portions 66 provides space in between the elastic elements 65 that permits the center portion 63 to deform into the volume defined by the concave surface 62 in the un-deflected or default position 610.
- the ramp-up stage is extended as compared to conventional dome assemblies and thus improves a tactile response of the dome assembly 50.
- non-linear deformation in the form of dome-buckling occurs along the first portions 66 and/or at the connections between the first portions 66 and the corresponding second portions 67.
- the periphery 64 may have a diameter of about 4-5 millimeters (mm), a height of the concave surface 62 may be about 0.26-0.36 mm and a thickness of the concave surface 62 may be about 0.035-0.06 mm.
- the dome-shaped element 60 as a whole provides for a travel distance between the un-deflected position 610 and the deflected position 612 of about 0.22-0.30 mm. Over that travel distance, the dome-shaped element 60 may be configured to provide a non-linear tactile response to a deflection force identified above as the pressing force.
- the non-linear tactile response is illustrated in FIG. 6 and includes a first part 100 and a second part 101.
- the first part 100 includes the ramp-up stage from an initial point of zero pressing force to a peak pressing force (PF) and is associated with a spring or linear deformation of the center portion 63 as aided by the first portions 66.
- the first part 100 terminates at a deflection of the concave surface 62 of about 0.14-0.28 mm and, more particularly, at a deflection of about 0.22 mm.
- the second part 101 is then associated with a dome-buckling collapse of the first portion 66 of the at least one of the elastic elements 65.
- the second stage terminates at a point proximate to 0.28 mm of travel distance at which the center portion 63 contacts the second contact pads 711 and the second portion 67 of the at least one of the elastic elements 65 resists further pressing force (RF).
- the dome-shaped element 60 provides for multiple advantages over conventional dome assemblies.
- the advantages include, but are not limited to, providing a dome-shaped element 60 for a keyboard assembly 70 that provides a non-linear tactile response to a 2 newtons (N) or less pressing/deflection force but does not include an elastomeric or compliant layer between the dome-shaped element 60 and the laminate 73.
- N 2 newtons
- the keyboard assembly 70 can be thinned as compared to keyboards with conventional dome assemblies without sacrificing tactile feel.
- the relative sizes of the center portion 63, the first portions 66 and the second portions 67 provide for an extended ramp-up stage of the first part 100 of the non-linear tactile response, which, as noted above, terminates at a deflection of the concave surface 62 of about 0.14-0.28 mm.
- the dome-shaped element 60 is formed such that the keyboard assembly 70 in thinned but permits increased ramp-up and travel distance as compared to convention dome assemblies in spite of the thinning. The increased ramp-up and travel distance provide for improved tactile feel.
- a dome-shaped element disposable in a keyboard of an electronic device includes a concave surface originating at a center and terminating at a periphery.
- the concave surface includes an annular array of elastic elements extending from the center to the periphery. At least one of the elastic elements includes a first portion with a first slope proximate to the center and a second portion with a second slope proximate to the periphery.
- the concave surface is deflectable between an un-deflected position and a deflected position and is configured to affect an operation of the electronic device in the deflected position.
- the dome-shaped element includes a concave surface originating at a center and terminating at a periphery disposed in contact with the first contact pad.
- the concave surface includes an annular array of elastic elements extending from the center to the periphery. At least one of the elastic elements includes a first portion with a first slope proximate to the center and a second portion with a second slope proximate to the periphery.
- the concave surface is deflectable between an un-deflected position and a deflected position and is configured such that the center contacts the second contact pad to thereby affect an operation of the electronic device in the deflected position.
- a keyboard assembly for an electronic device includes a substrate, a laminate disposed at a distance from the substrate and a multiple-sloped dome interposed between the laminate and the substrate.
- the multiple-sloped dome includes a peripheral portion contacting the substrate and a central portion contacting the laminate and is formed such that the central portion is biased to remain separated from the substrate and to provide a non-linear tactile response to a pressing force applied to the laminate to thereby urge the central portion into contact with the substrate.
- a dome-shaped element for use with a handheld electronic device and includes concave surface as described above but does not include an elastomeric or compliant layer between the concave surface and the laminate.
- the dome-shaped element is therefore relatively thin but nevertheless provides for an increased ramp-up deflection stage and a non-linear response to a pressing/deflection force.
