Description
- This application is a continuation of U.S. patent application Ser. No. 12/241,015, filed Sep. 29, 2008, which claims the benefit of U.S. Provisional Application No. 61/010,138, filed Jan. 4, 2008, and of U.S. Provisional Patent Application No. 61/010,726, filed Jan. 11, 2008, all of which are incorporated by reference herein in their entireties.
- This invention is directed to a touchpad assembly for use in an electronic device.
- Some electronic devices, and in particular laptop and desktop computers, may include several types of input mechanisms. One of the input mechanisms may include a touchpad (e.g., for controlling a pointer displayed on a screen) and one or more buttons (e.g., a pick button to provide selection instructions). The touchpad and pick button may be coupled to the electronic device using several different approaches. In some embodiments, the electronic device may include a first opening through which a user may access the touchpad, and a second opening through which the pick button may extend.
- In many electronic devices, the pick button provided is relatively small, and may be supported from within the electronic device using one or more springs (e.g., helical springs) compressed underneath the pick button. In addition, the small size of the button allows a user to actuate the button by depressing the button with the same amount of force independent of where the button is pressed—in other words, the small size of the button prevents it from deflecting away from a switch located underneath the button. While such existing touchpad assemblies may be sufficient for smaller touchpads and pick buttons, they lack the mechanical features necessary to provide proper support and a pleasant user experience when the touchpad, pick button, or both become larger (e.g., for example in a multi-touchpad) or are placed in smaller electronic devices (e.g., very thin laptop computers, such as the MacBook Air™, available from Apple Inc. of Cupertino, Calif.).
- Touchpad assemblies for use in an electronic device are provided. The touchpad assemblies may be operative to support large touchpads (e.g., a multi-touchpad) and associated large pick buttons (e.g., a pick button extending the length of the multi-touchpad).
- In some embodiments, a touchpad assembly may be provided. The touchpad assembly may include a pick button and an assembly frame operative to be secured to an electronic device housing. The assembly frame may include a support plate operative to support a touchpad and a bracket coupled to a side of the support plate such that the bracket defines a recess. The pick button may be placed within the recess such that a switch is located between the pick button and the bracket. At least one spring may be coupled to an end of the pick button and to the housing to retain the pick button within the housing. In some embodiments, the pick button may include a rib or other element varying the cross-section of the button, for example to prevent the pick button from deflecting when it is pressed, or to make the distance traveled to actuate the switch uniform.
- In some embodiments, an electronic device may be provided. The electronic device may include a housing with an opening, and an assembly frame operative to support a touchpad and a pick button. The assembly frame may be coupled to the housing such that a substantial portion of the assembly frame is accessible through the opening. A pick button may be placed in the assembly frame. At least one pad may be placed on the housing adjacent to the pick button such that the pad may muffle sounds created when the pick button is depressed (e.g., to actuate a switch).
- In some embodiments, an assembly frame of a touchpad assembly may be provided. The assembly frame may include a support plate operative to support a touchpad, where the support plate includes at least one plate tab operative to be placed in contact with an electronic device housing. The assembly frame may also include a bracket operative to receive a pick button. The bracket may include at least one bracket tab operative to be placed in contact with the electronic device housing. To ensure that the support plate is sufficiently rigid, the support plate and bracket may be constructed from the same piece of material (e.g., stamped from a single piece of metal).

-
FIG. 1 is an exploded perspective view of an illustrative touchpad assembly coupled to a keyboard frame in accordance with some embodiments of the invention.Frame 102 may define a structure on which different electronic device components may be mounted. For example,frame 102 may be a wall portion of an electronic device housing, and may include a keyboard frame for retaining keys used to provide inputs to the electronic device, and for providing access to a touchpad for controlling the display of content by the electronic device.Touchpad assembly 100 may include or be operative to support a touchpad and at least one pick button such that the touchpad and at least one pick button are accessible to a user through opening 104 offrame 102. -
Touchpad assembly 100 may includeassembly frame 110 operative to provide support for a touchpad.Assembly frame 110 may include several portions, includingsupport plate 112 andbracket 120.Support plate 112 may be operative to provide support for a touchpad, such thatsupport plate 112 may provide resistance for a user's finger as it moves across the touchpad.Support plate 112 may substantially match the size and shape of at least a portion of opening 104. In some embodiments,support plate 112 may be sized such that at least a portion ofsupport plate 112 extends beyond the periphery of opening 104 on one or more sides of opening 104. For example, if opening 104 substantially defines a rectangle,support plate 112 may extend beyond the periphery of the sides of the rectangle other than the side adjacent to the pick button of touchpad assembly 100 (e.g., the side ofopening 104 that is adjacent to the edge of frame 102). - In some embodiments,
support plate 112 may include one ormore tabs 114, for example, to allow wiring to connect a touchpad on the top surface ofsupport plate 112 and electronic device components adjacent to the bottom surface ofsupport plate 112. Instead or in addition,tabs 114 may be used to couplesupport plate 112 toframe 102, for example using a mechanical fastener (e.g., a screw), tape, an adhesive, an interlocking mechanism or component, or any other suitable approach. - Bracket 120 may define a trough or groove operative to receive a
pick button 130. For example,bracket 120 may includerecessed portion 122 defined bysidewalls Bracket 120 may be coupled to supportplate 112 using any suitable approach. For example,bracket 120 andsupport plate 112 may be manufactured as two distinct components and assembled together (e.g., using an adhesive, tape, a mechanical fastener, welding, soldering, or heat treatment). As another example,bracket 120 andsupport plate 112 may be manufactured as a single component (e.g., a single stamped component).Bracket 120 may be connected to supportplate 112 bysidewall 124, and coupled toframe 102 usingsidewall 126. For example,sidewall 126 may include one ormore tabs 128 extending from the end ofsidewall 126, for example, at substantially the same height assupport plate 112.Tabs 128 may be sized such thattabs 128 extend beyond the periphery of opening 104 whenassembly frame 110 is coupled toframe 102. For example,tabs 128 may be operative to extend over the side of the rectangle that is adjacent to the pick button of touchpad assembly 100 (e.g., the side ofopening 104 that is adjacent to the edge of frame 102).Tabs 128 may be used to couplebracket 120 toframe 102 using any suitable approach, including for example using a mechanical fastener (e.g., a screw), tape, an adhesive, an interlocking mechanism or component, or any other suitable approach. -
Support plate 112 andbracket 120 may be constructed from any suitable material. In particular, the material used for one or both ofsupport plate 112 andbracket 120 may be selected from material having sufficient strength to resist pressure caused by a user's finger on the touchpad. The material used may also be selected based on weight, aesthetic, and ease of manufacturing considerations. For example, the material used forsupport plate 112 may include at least one of a metal, composite material, or plastic (e.g., a stamped aluminum or steel component). -
Touchpad assembly 100 may includepick button 130 for providing inputs (e.g., selection instructions) to the electronic device.Pick button 130 may form an elongated structure having a substantially rectangular cross-section.Pick button 130 may be inserted in opening 104 such that the pick button is aligned withbracket 120. A switch 132 may be positioned between the lower surface ofpick button 130 andbracket 120 such that whenpick button 130 is pressed,pick button 130 may be brought in close proximity withbracket 120 such that switch 132 is compressed between the pick button and the bracket and thereby actuated. In some embodiments, switch 132 may be coupled to pickbutton 130 and connected to other electronic device components (e.g., other components located in proximity of frame 102) using trace 134. -
Pick button 130 maybe coupled to frame 102 using any suitable approach. In some embodiments,pick button 130 may be coupled such thatpick button 130 may be deflected to provide an input and return to a rest position in which switch 132 is not closed. For example,pick button 130 may be coupled to frame 102 using one or more pick button springs 140 coupled to ends 136 and 137 ofpick button 130. Each ofends spring 140 such that the overall profile ofpick button 130 andspring 140 may remain substantially the same (e.g., the depth of each recessed platform at ends 136 and 137 may be substantially equal to the thickness of spring 140). By providing springs that extend away from underneathpick button 130, the overall thickness ofpick button 130 and bracket 120 (e.g., the distance between the top ofpick button 130 and the bottom of bracket 120) may be minimized. -
Springs 140 may include any suitable type of spring, including for example a tension spring, extension spring, compression spring, torsional spring, wire spring, coil spring, flat spring, cantilever spring, helical spring, hairspring, balance spring, leaf spring, or any other suitable type of spring. The springs may have any suitable spring constant or value defining the elasticity of the spring, including, for example, a value selected based on the distance required to actuate switch 132, the desired tactile feedback, and size considerations.Springs 140 may be coupled to pickbutton 130 andframe 102 using any suitable approach, including, for example, an adhesive, tape, mechanical fastener (e.g., a screw), an engagement mechanism (e.g., a snap), or any other suitable approach. -
Pick button 130 may be coupled totouchpad assembly 100 such that tactile and audio feedback are provided when a user actuates the pick button. For example,pick button 130 may provide an audible “click” sound when a user pressespick button 130. To prevent audio feedback as the pick button returns to its initial position (e.g., so as not to confuse a user whether switch 132 was closed once or twice),frame 102 may include one ormore pads 150 for muffling the sound of the pick button returning to the initial, un-clicked position. -
FIG. 2 is a perspective view, similar toFIG. 1 , of the bottom of an illustrative assembled frame and touchpad assembly in accordance with some embodiments of the invention.FIG. 3 is a perspective view of the top of the illustrative assembled frame and touchpad assembly in accordance with some embodiments of the invention.Touchpad assembly 200 may includeassembly frame 210 coupled toframe 202. Pick button 230 andtouchpad support plate 212 may be accessible from the outside offrame 202 throughopening 204. Pick button 230 may be supported bybracket 220 oftouchpad assembly frame 210, and retained at least partially within opening 204 bysprings 240. -
FIG. 4 is a perspective view of an illustrative assembly frame for use in an electronic device in accordance with some embodiments of the invention, andFIG. 5 is a cross-sectional view of the assembly frame ofFIG. 4 in accordance with some embodiments of the invention.Assembly frame 400 may includesupport plate 412 andbracket 420, such that a touchpad may be placed onsupport plate 412 and a pick button may be positioned withinbracket 420.Support plate 412 may form a substantially flat surface constructed from a suitable rigid material such that when a user presses the touchpad,support plate 412 may resist the user's contact and prevent the touchpad from flexing or deflecting during use. -
Support plate 412 may have any suitable size. In some embodiments,support plate 412 may be larger than a touchpad placed onsupport plate 412. To couplesupport plate 412 to an electronic device frame,support plate 412 may include one ormore tabs 414 operative to be placed adjacent to the electronic device frame (e.g.,tabs 414 may extend beyond the periphery of an opening within the frame).Tabs 414 may extend from any suitable side ofsupport plate 412, including for example from the three sides ofsupport plate 412 that are not in contact with bracket 420 (e.g., the sides that extend beyond the periphery of the opening in the frame). - To ensure that sufficient support is provided to the remaining side of
support plate 412,bracket 420, which may be coupled to the frame viatabs 428, may be coupled to supportplate 412 such that the support provided tobracket 420 may be transferred to supportplate 412.Bracket 420 andsupport plate 412 may be coupled using any suitable approach, including for example using welding, soldering, a mechanical fastener, an adhesive, tape, or any other suitable coupling mechanism that provides sufficient stiffness betweenbracket 420 and support plate 412 (e.g., to transfer the load). In some embodiments,bracket 420 andsupport plate 412 may be constructed from a single piece of material (e.g., stamped from a single sheet of metal). By combiningbracket 420 andsupport plate 412, the two components ofassembly frame 400 may support each other within an electronic device frame, and allowassembly frame 400 to be smaller, thus allowing more flexibility in the design of the electronic device. -
Bracket 420 may be constructed using any suitable approach. In some embodiments,bracket 420 may include recessedportion 422, which may include a substantially flat surface. Recessedportion 422 may be placed in contact with a switch coupled to a pick button placed withinbracket 420 to provide resistance for the switch to close when the pick button is pressed intobracket 420.Bracket 420 may includesidewalls portion 422 to supportplate 412 andtabs 428.Sidewalls portion 422 at any suitable angle (e.g., 90 degrees). Recessedportion 422 may include one ormore apertures 421 providing clearance for springs used to couple the pick button to the electronic device. For example, recessedportion 422 may include twoapertures 421 at opposite ends of recessedportion 422 to provide clearance for springs used to connect the ends of the pick button to an electronic device frame. - In some embodiments, the depth of recessed
portion 422 may vary. As shown inFIG. 5 ,support plate 412 may constitute a substantially planar surface coupled tobracket 420. Recessedportion 422 may includeplanar portion 423 a, which may be substantially parallel to supportplate 412 and may be connected to supportplate 412 bysidewall 424, andangled portion 423 b, which may be a prolongation ofplanar portion 423 a that is substantially planar and slightly angled away fromplanar portion 423 a. The end ofangled portion 423 b may be coupled tosidewall 426, which may in turn be coupled totab 428 for connectingassembly frame 400 to an electronic device frame. The dimensions and orientations ofplanar portion 423 a,angled portion 423 b, and sidewalls 424 and 426 may be selected based on any suitable criteria, including for example dimensions of the pick button placed inbracket 420. -
FIG. 6 is a cross-sectional view of an illustrative touchpad assembly for use with an electronic device in accordance with some embodiments of the invention.Touchpad assembly 600 may includeassembly frame 610 and pickbutton 630.Touchpad assembly 600 may be coupled to frame 602 of the electronic device, forexample using tab 628 ofassembly frame 610.Assembly frame 610 may includesupport plate 612 andbracket 620, and may be coupled to frame 602 such that portions ofsupport plate 612 andbracket 620 may be accessible through an opening offrame 602.Pick button 630 may be positioned withinbracket 620 such thatswitch 632 may be placed betweenbottom surface 634 ofpick button 630 andplanar portion 623 a of recessedportion 622 ofbracket 620. In addition,bottom surface 634 andplanar portion 623 a may be substantially parallel to ensure that proper contact is maintained withswitch 632. The thickness ofpick button 630 and depth of recessed portion 622 (e.g., determined by the length ofsidewalls 624 and 626) may be selected such thatswitch 632 may be substantially in contact with bothbottom surface 634 andplanar portion 623 a without being actuated whenpick button 630 is at rest. -
Pick button 630 may have any suitable profile. In particular, the profile ofpick button 630 may be selected such that a user must deflectpick button 630 by the same amount wherever the user places his finger (e.g., on a portion ofpick button 630 neartab 628 or near support plate 612). For example,pick button 630 may include a variable cross-section based on the distance of each portion ofpick button 630 to switch 632. In particular,pick button 630 may includeangled face 633 connectingproximal end 635 ofpick button 630 to the portion ofpick button 630 adjacent to switch 632 (e.g., bottom surface 634). Instead of using a symmetrical or similar angled portion between the portion ofpick button 630 adjacent to switch 632 anddistal end 636,pick button 630 may includerib 637 having a larger width than other portions ofpick button 630 to reduce the travel necessary to closeswitch 632 when a user pressespick button 630 neardistal end 636. In some embodiments,rib 637 may also be operative to preventpick button 630 from deflecting or bending when a user presses an area neardistal end 636 or near a tip portion of button 630 (e.g., proximate a spring of the assembly), which would increase the travel required bybutton 630 to actuateswitch 632 or preventbutton 630 from actuatingswitch 632 altogether. - In some embodiments, the touchpad assembly may include one or more components for modifying or controlling tactile feedback, audio feedback, or both provided in response to a user pressing the pick button and closing the switch (e.g., inverting a dome switch positioned underneath the pick button).
FIG. 7 is a bottom view of an illustrative frame having acoustic pads for controlling audio feedback in accordance with some embodiments of the invention. Frame 702 may include opening 704 for receiving a touchpad assembly. To reduce the sound of a pick button striking frame 702 when it is pressed, frame 702 may includepads Pads pads 750 and 754).Pads - The above-described embodiments of the invention are presented for purposes of illustration and not of limitation, and the invention is limited only by the claims which follow.
