Description:
TECHNICAL FIELD 
     The disclosure relates generally to electronic devices, and more particularly, to input devices for electronic devices. 
     BACKGROUND 
     Current electronic devices typically include various input devices. These input devices allow a user to interact with the electronic device during operation. One conventional input device frequently included in electronic devices is a push-button. Push-buttons allow a user to easily engage the electronic device by engaging an internal switch to either an open position, or closed position, which may ultimately send an electronic signal to a component of the electronic device. 
     However, because of the actuation or movement required for a push-button to operate, the configuration of conventional push-buttons may make the push-button vulnerable to operational degradation, and/or may allow the push-button to be undesirably exposed to harmful elements. For example, conventional push-buttons and its internal components may be vulnerable to damage caused by exposure to water as a result of inadequate sealing conditions within the push-button. That is, conventional push-buttons often including sealing components (e.g., rubber diaphragms, O-ring seals) to substantially prevent water from entering the push-button and contacting the internal components of the push-button. However, these seal components typically have finite lifespans because of their design, composition and/or interaction within the push-button. During the lifespan of the push-button these seal components become less effective in sealing the push-button due to abrasion, cracking and/or general fatigue. 
     In addition, the configuration of conventional push-buttons, and specifically the through hole to the interior of a housing for the push-button, prevents any seal component used within the push-button from guaranteeing a perfect seal within the push-button. That is, due to the openings operationally-required in conventional push-buttons, no seal component may be implemented within the push-button to completely seal the push-button from water, without negatively effecting the function or actuation of the push-button. As a result, seal components implemented in conventional push-buttons may only minimize the risk of damage to push-buttons from water exposure, but may not completely prevent the damage. 
     SUMMARY 
     Generally, embodiments discussed herein are related to a waterproof button assembly and a method of assembling the waterproof button assembly. The waterproof button assembly may include a housing made of a single, integral component, and a button positioned within the housing. Furthermore, the waterproof button assembly may include a sensing component positioned below the housing. By including a single, integral component to form the housing, there may be no through holes in the button assembly to allow water to reach the sensing component. That is, any water that may enter the housing between the button and the housing, may be substantially trapped within the housing, and may not come in contact with the sensing component of the waterproof button assembly positioned below and/or outside of the housing. 
     One embodiment may include a waterproof button assembly. The waterproof button assembly may include a housing having an opening, and a button positioned at least partially within the housing via the opening. Additionally, the waterproof button assembly may include a plurality of engagement components positioned on opposite-distal ends of the button.

As discussed herein, waterproof button assembly  100  may be utilized by electronic device  10  to provide user input and/or allow the user to interact with the various functions of electronic device  10 . 
     Turning to  FIG. 2 , a partially exploded perspective view of a waterproof button assembly  100  is shown according to embodiments of the invention. Waterproof button assembly  100  may include a housing  102  including an opening  104 . Housing  102  may include a single, continuous component. That is, as shown in  FIG. 2 , opening  104  may only extend through a top surface  106  and extend partially through housing  102 , such that housing  102  may be formed from a single, continuous component. As discussed herein, housing  102  may be configured to receive a button  108  via opening  104 . Opening  104  may be configured as a substantially elongated ellipse as shown in  FIG. 2 . However, it is understood that the shape of opening  104  of housing  102  may be dependent, at least in part, on the shape of button  108 . 
     As shown in  FIG. 2 , housing  102  may also include a plurality of apertures  110  formed in a sidewall  112  of housing  102 . Each of the plurality of apertures  110  may include a cavity or recess formed partially through sidewall  112  of housing  102 , such that housing  102  may remain a single, continuous component. Briefly turning to  FIG. 4 , with continued reference to  FIG. 2 , housing  102  may include two apertures  110  positioned or formed within sidewall  112 , opposite one another. That is, each of the two apertures  110  may be formed within sidewall  112  and may be positioned on opposite ends of housing  102 . As discussed herein, each of the plurality of apertures  110  of housing  102  may be configured to receive a portion of button  108  to aid in coupling or retaining button  108  within housing  102 . As shown in  FIGS. 2 and 4 , sidewalls  112  of housing  102  may be substantially thick to provide a rigid support for button  108  during actuation. As discussed herein, sidewalls  112  may also provide support for segments of a base portion of housing  102  positioned directly adjacent sidewalls  112  during actuation of button  108 . 
     Housing  102  may be made of any conventional material capable of forming a substantially rigid structure. That is housing  102  may be made from any conventional material including, but not limited to: polymer, metal, glass, etc. Additionally, housing  102  may be made using any conventional manufacturing process or combination of processes including, but not limited to: molding, casting, milling, drilling, forming, joining, etc. 
     Waterproof button assembly  100 , as shown in  FIG. 2 , may also include button  108  configured to be positioned within housing  102 . More specifically, with reference to  FIG. 4 , button  108  may be positioned at least partially within housing  102  via opening  104 . In an embodiment, for example as shown in  FIG. 4 , substantially all of button  108  may be positioned within housing  102 , such that top surface  114  of button  108  may be in planar alignment with top surface  106  of housing  102 . In the embodiment, and as discussed herein, top surface  114  of button  108  may be in planar alignment with top surface  106  of housing  102  during an unactuated state of button  108  and may be positioned substantially below top surface  106  during an actuated state (e.g.,  FIG. 6C ). In an alternative embodiment, top surface  114  and a portion of button  108  may be exposed and extend above top surface  106  of housing  102 . In the alternative embodiment, top surface  114  of button  108  may extend above top surface  106  of housing  102  during both an actuated and unactuated state of button  108 , or may only extend above housing  102  during an unactuated state of button  108 . 
     As shown in  FIG. 2 , button  108  may include a upper portion  116  including top surface  114 . Upper portion  116  may include a perimeter  118  that may be positioned substantially adjacent sidewalls  112  or may substantially contact sidewalls  112  when button  108  is positioned within housing  102  (e.g.,  FIG. 4 ). Perimeter  118  of button  108  may include a shape substantially identical to opening  104  formed through top surface  106  of housing  102 . That is, as shown in  FIG. 2 , perimeter  118  of button  108  and opening  104  of housing  102  may include substantially similar curved and linear portions, where the curvature of a curved portion of button  108  is substantially concentric or in alignment with the curvature of a corresponding curved portion of opening  104 . As a result, perimeter  118  of button  108  and opening  104  of housing  102  may be substantially concentric or nested, where at least a portion of button  108  is positioned within opening  104  of housing  102 . As discussed herein, the distance or space between perimeter  118  of button  108  and sidewalls  112  of housing  102  may be substantially minimal where perimeter  118  is positioned substantially adjacent sidewalls  112  or may not be present where perimeter  118  contacts sidewalls  112 . The minimal or non-existent distance or space between perimeter  118  of button  108  and sidewalls  112  of housing  102  may aid in preventing undesirable elements, such as liquid, from entering opening  104  of housing  102 , as discussed herein. 
     Button  108  may also include a lower portion  120  positioned opposite and/or below upper portion  116 . As shown in  FIGS. 2-3B , lower portion  120  of button  108  may include a plurality of grooves  122  positioned on distal ends  124 ,  126  of button  108 , substantially adjacent upper portion  116 . The plurality of grooves  122  may include a recess or reduced body portion formed in lower portion  120  of button  108 . As shown in  FIG. 3B , the plurality of grooves  122  may include an inner surface  123  which may include a substantially U-shaped configuration. That is, inner surface  123  of each of the plurality of grooves  122  may include a curvature that is substantially concentric or in alignment with the curved portion of perimeter  118 , and may include linear portions that are substantially parallel or in alignment with the linear portions of perimeter  118 . In forming the plurality of grooves  122 , lower portion  120  of button  108  may also include shelf portions  128  positioned on distal ends  124 ,  126  of button  108 , adjacent the plurality of grooves  122 . Briefly turning to  FIG. 4 , lower portion  120  of button  108  may be in substantial alignment within apertures  110  formed in sidewalls  112  when button  108  is positioned within housing  102 . More specifically, each of the plurality of grooves  122  and the respective shelf portions  128  formed in lower portion  120  of button  108  may be in alignment with one of the plurality of apertures  110  formed in sidewalls  112  when button  108  is positioned within housing  104  and button  108  is in an actuated or unactuated state, as discussed herein. 
     Button  108  may be made of any conventional material capable of forming a substantially rigid structure. That is button may be made from any conventional material including, but not limited to: polymer, metal, glass, etc. Additionally, button  108  may be made using any conventional manufacturing process or combination of processes including, but not limited to: molding, casting, milling, drilling, forming, joining, etc. 
     Waterproof button assembly  100  may also include a plurality of engagement components  130  positioned on opposite distal ends  124 ,  126  of button  108 . As discussed herein, the plurality of components  130  may be configured to retain button  108  within housing  102 . In an embodiment as shown in  FIGS. 2-4 , the plurality of engagement components  130  may be include a plurality of clips  132 . Each of the plurality of clips  132  may be slidingly engaged to one of the plurality of grooves  122  of button  108 . More specifically, as shown in  FIG. 3B , each clip  132  may contact a portion of inner surface  123  of each of the plurality of grooves  122 , and may be substantially free to move distally while slidingly engaged to button  108 . As shown in  FIGS. 2 and 3B , a portion of clips  132  may extend outward, beyond distal ends  124 ,  126  of button  108  when slidingly engaged to button  108 . Angled surfaces  134  of center portion  136  of button  108  may substantially maintain clips  132  in a position where a portion of clips  132  extend beyond distal ends  124 ,  126  of button  108 . More specifically, as will be understood with reference to  FIG. 3B , as clips  132  move toward the center of button  108  and/or center portion  136  and clips  132  no longer extend beyond distal ends  124 ,  126 , ends  138  of clips  132  may contact angled surface  134  and may be angularly displaced, such that the width of clips  132  may be temporarily increased. As ends  138  move along angled surface  134  and closer to center portion  136 , a force (e.g., spring force) may drive clips  132  distally outward, away from center portion  136  to extend beyond distal ends  124 ,  126  of button  108 . As such, clip  132  may only temporarily fail to extend beyond distal ends  124 ,  126  of button  108 , before the force (e.g., spring force) pushes ends  138  of clip  132  away from center portion  136  and a portion of clips  132  extend beyond distal ends  124 ,  126  of button  108 . To provide such a force (e.g., spring force) for correcting the position of clips  132 , clips  132  may include any conventional material capable of being substantially rigid, but having elastic-properties including, but not limited to, polymers (e.g., plastics) and metals (e.g., shape-memory alloys). 
     Clips  132  may also contact and/or be supported by a contact surface  140  of shelf portion  128  of button  108 . That is, clips  132  may slidingly engage inner surface  123  of grooves  122 , and may be further maintained and supported within groove  122  by resting upon contact surface  140  of shelf portion  128 . Contact surface of shelf portion  128  may substantially prevent clips  132  from rotating within grooves  122  of button  108 . That is, contact surface  140  of shelf portion  128  and upper portion  116  of button  108  may be outer barriers to substantially maintain clips  132  within groove  122  and prevent clips  132  from rotating while slidingly engaged to inner surface  123  of grooves  122 . 
     Turning to  FIG. 4 , a cross-sectional side view of waterproof button assembly  100  of  FIGS. 2-3B  is shown according to embodiments of the invention. It is understood that similarly numbered components may function in a substantially similar fashion. Redundant explanation of these components has been omitted for clarity. As shown in  FIG. 4 , when button  108  is positioned within housing  102 , lower portion  120  of button  108  may be aligned with apertures  110  formed in sidewalls  112  of housing  102 . More specifically, at least a portion of groove  122  of button  108  and engagement component  130 , shown as clips  132 , may be substantially aligned with apertures  110  of housing  102 . At least a portion of each of the engagement components  130  may be positioned within one of the plurality of apertures  110  formed in sidewall  112  of housing  102 . For example, as shown in  FIG. 4 , a portion of each of clips  132  positioned within grooves  122  formed on opposite distal ends  124 ,  126  of button  108  may be positioned within each of the plurality of apertures  110  of housing  102 . While button  108  is positioned in housing  102 , and/or waterproof button assembly  100  is assembled, a portion of engagement components  130 , and specifically clips  132 , may be positioned within aperture  110  to retain button  108  within housing  102 . Engagement component  130 , and specifically clips  132  slidingly engaged to grooves  122  of button  108 , may retain button  108  within housing  102  by engaging an underside surface  142  of aperture  110  when button  108  is positioned within housing  102 . That is, after button  108  is installed and positioned within housing  102 , as discussed herein, clips  132  may extend distally beyond distal ends  124 ,  126  of button  108  and a portion of each of the clips  132  may be positioned within aperture  110  to engage underside surface  142 . Once engaged with underside surface  142 , button  108  may be retained within housing  102 , as clips  132  may substantially hold button  108  within housing  102  and/or prevent button  108  from being removed from housing  102  via opening  104 . 
     As shown in  FIG. 4 , waterproof button assembly  100  may also include a first support  144  positioned within housing  102  adjacent button  108 . More specifically, first support  144  may be positioned within opening  104  of housing  102  and may be positioned between a base portion  146  of housing  102  and button  108 . First support  144  may be configured to include a width marginally smaller than the width of opening  104  formed in housing  102 , such that first support  144  may be positioned adjacent to sidewalls  112  of opening  104 . As a result of the marginal difference between the width of first support  144  and opening  104 , lateral movement of first support  144  within housing  102  may be substantially minimal during operation of waterproof button assembly  100 . As discussed herein, during actuation of button  108  of waterproof button assembly  100 , first support  144  may be slightly displaced or deformed toward sidewalls  112  of housing  102  to dissipate at least a portion of the force placed on waterproof button assembly  100  during actuation. As shown in  FIG. 4 , first support  144  may include a bottom ridge  148  formed on a bottom surface  150  of first support  144 . Bottom ridge  148  may extend at least partially around the perimeter of first support  144  and may displace a portion of a force applied to button  108  during actuation, as discussed herein. First support  144  may also include top ridge  102  formed on a top surface  106  of first support  144 . Top ridge  102  of first support  144  may extend at least partially around an opening  104  formed through first support  144 , and may contact lower portion  120  of button  108  during the actuation of button  108 , as discussed herein. That is, top ridge  102  of first support  144  may contact lower portion  120  of button  108  during actuation to substantially prevent button  108  from being actuated to an undesirable position, which may ultimately put an undesirable strain on engagement component  130  (e.g., clips  132 ). As discussed herein, first support  144  may partially deform during the initial actuation of button  108  of waterproof button assembly  100 . As such, first support  144  may include any conventional material being relatively rigid, and including semi-elastic characteristics. 
     Waterproof button assembly  100  may also include a second support  158  positioned within housing  102  adjacent button  108 . As shown in  FIG. 4 , second support  158  may be substantially surrounded by first support  144 , and may be positioned within opening  104  of first support  144 . Second support  158  may contact base portion  146  of housing  102  and may be positioned substantially in the center of housing  102 , between button  108  and base portion  146 . Additionally, as shown in  FIG. 4 , second support  158  may be positioned in alignment with a contact portion  160  of button  108 . As discussed herein, contact portion  160  of button  108  may aid in the operation of waterproof button assembly  100  during the actuation of button  108 . Second support  158  of waterproof button assembly  100  may be a solid structure having substantially rigid and/or low-elastic characteristics. As discussed herein, during the actuation of button  108  of waterproof button assembly  100 , second support  108  may aid in deflecting base portion  146  of housing  102 . That is, and as discussed herein, second support  158  may be utilized to aid in the deflection of base portion  146  of housing  102  when button  108  is actuated from an applied-predetermined force or load. 
     As shown in  FIG. 4 , waterproof button assembly  100  may also include a tactile dome  162  positioned between second support  108  and button  108 . More specifically, tactile dome  162  may be positioned above second support  108  and coupled to first support  144  adjacent top ridges  102 . Tactile dome  162  may also be positioned below lower portion  12  of button  108 . Tactile dome  162  may be in constant contact with button  108 , and specifically contact portion  160  of lower portion  120  of button  108 . As discussed herein, during the actuation of button  108  of waterproof button assembly  100 , tactile dome  162  may receive a force from contact portion  160  of button  108 , and may substantially buckle or deform to provide tactile feedback to a user of waterproof button assembly  100 . As shown in  FIG. 4 , the shape (e.g., dome) of tactile dome  162  may contact portion  160  of button  108 , and may be substantially push button  108  toward top surface  106  of housing  102 . More specifically, tactile dome  162  may be responsible for applying a force on button  108 , via contact portion  160 , in a direction toward top surface  106  of housing  102 , such that clips  132  may be pushed to contact underside surface  142  of opening  110  of housing  102  to retain button  108  within housing  102 . Tactile dome  162  may be configured as any conventional tactile dome  162  configured to be utilized by a button assembly such as waterproof button assembly  100 . 
     In some embodiments, as shown in  FIG. 4 , waterproof button assembly  100  may include a sensing component  164  positioned adjacent housing  102 . More specifically, sensing component  164  may be positioned outside of housing  102 , adjacent base portion  146 , and in substantial alignment with second support  108  of waterproof button assembly  100 . As discussed herein, sensing component  164  may sense actuation of button  108  within housing  102 , and may provide an electronic signal to a distinct component or system utilizing waterproof button assembly  100 . Sensing component  164  may include any conventional sensor system configured to sense actuation of button  108 , via a deflection of base portion  146  of housing  102 , and provide a signal indicating actuation. In one embodiment, as shown in  FIG. 4 , sensing component  164  may be configured as a piezoelectric sensor  166 . As discussed herein, when button  108  is actuated, and base portion  146  of housing  102  is deflected into piezoelectric sensor  166 , piezoelectric sensor  166  may be deformed by base portion  146  and may send an electrical signal to another component of the electronic device (not shown) via wires  168 . 
     Turning to  FIGS. 5-6C , a process of actuating button  108  within waterproof button assembly  100  may now be discussed. Specifically,  FIG. 5  is a flowchart depicting one sample method  500  for actuating button  108  within waterproof button assembly  100 .  FIGS. 6A-6C  may depict waterproof button assembly  100  undergoing method  500 , as depicted in  FIG. 5 . It is understood that similarly numbered components may function in a substantially similar fashion. Redundant explanation of these components has been omitted for clarity. 
     In operation  502 , waterproof button assembly  100  included in electronic device  10  may be provided in an unactuated state. As shown in  FIG. 6A , and discussed herein with respect to  FIGS. 2-4 , top surface  114  of button  108  may be in planar alignment with top surface  106  of housing  102 . Additionally, contact portion  160  of button  108  may be in contact with tactile dome  162 , where tactile dome  162  is not displaced or deformed by contact portion  160  of button  108 . That is, button  108  may rest upon tactile dome  162  via contact portion, without displacing or deforming tactile dome  162  in an unactuated state. Also shown in  FIG. 6A , base portion  146  may not be displaced or deformed in an unactuated state of button  108  of waterproof button assembly  100 . Base portion  146  of housing  102  may be in substantial parallel alignment with top surface  106  of housing  102  in an unactuated state of button  108 , and may include uniform thickness (T). As a result, in an unactuated state of button  108 , piezoelectric sensor  166  (e.g., sensing component  164 ) may also be in substantial parallel alignment with top surface  106  of housing  102 , and may not be displaced or deformed by base portion  146  of housing  102 . 
     In operation  504 , a force (F) may be applied to button  108  of waterproof button assembly  100 . As shown in  FIG. 6B , the force (F) may be applied to top surface  114  of button  108 , and may be applied in a direction toward base portion  146  of housing  102 . When the force (F) is initially applied to button  108 , button  108  may be in a partially actuated state. In the partially actuated state, as shown in  FIG. 6B , button  108  may be slightly displaced. That is, engagement components  130 , and specifically clips  132 , of button  108  may no longer contact underside surface  142  of apertures  110 , and button  108  may float within opening  104  of housing  102 . Furthermore, in the initial applying of the force (F), contact portion  160  of button  108  may remain in contact with tactile dome  162 , and may apply enough of a force to displace tactile dome  162  in a lateral direction. That is, as shown in  FIG. 6B , and with comparison to  FIG. 6 , tactile dome  162  may retain its dome shape when the force (F) is initially applied to button  108 , however, the height of tactile dome  162  may be reduced as a result of the force (F) slightly flattening tactile dome  162 . When tactile dome  162  is displaced in a lateral direction, the applied forced (F) may initially be dispersed or distributed throughout first support  144 . More specifically, as tactile dome  162  is displaced in a lateral direction, tactile dome  162  may apply a substantially lateral force on top ridge  102  of first support  144 , which may in turn increase the width of first support  144  positioned within opening  104  of housing  102 . Additionally, the space between first support  144  and second support  108  may also increase, as tactile dome  162  is displaced laterally as a result of the force (F) being initially applied to button  108 . This force may continue to be distributed from top ridge  152  to bottom ridge  148  of first support  144 . As shown in  FIG. 6B , bottom ridge  148  may direct the force against base portion  146  near sidewalls  112  of housing  102 . As discussed herein, sidewalls  112  may be substantially thick to prevent portions of base portion  146  positioned directly adjacent sidewalls  112  from deforming under the force (F) in its initial application. As such, in the partially actuated state, base portion  146  of waterproof button assembly  100  may remain substantially free from displacement or deformation, and may maintain uniform thickness (T). Additionally, as a result of tactile dome  162  distributing the initial force only to first support  144 , second support  108  may remain substantially free from displacement or deformation. Finally, piezoelectric sensor  166  (e.g., sensing component  164 ) may also be unaffected by the force (F) initially applied to button  108 , and may remain in substantial parallel alignment with top surface  106  of housing  102 . That is, because the force (F) does not initially deform base portion  146 , piezoelectric sensor  166  may not be deformed or displaced, and no electric current may be passed to distinct components of electric device  10  ( FIG. 1 ) when button  108  is in a partially actuated state. 
     In operation  506 , the force (F) may be applied to base portion  146  of housing  102  of waterproof button assembly  100 . As shown in  FIG. 6C , the force (F), as previously discussed with respect to operation  504  and  FIG. 6B , may continue to be applied to top surface  114  of button  108 , and may be applied in a direction toward base portion  146  of housing  102 . When the force (F) is applied to base portion  146 , button  108  may be in an actuated state. In operation  506 , force (F) may be applied with a continuous magnitude over a period of time required for button  108  to be in an actuated state (e.g.,  FIG. 6C ), or the force (F) may vary, where the force applied for button  108  to be in an actuated state (e.g.,  FIG. 6C ) is greater than the force applied to for button  108  to be in a partially actuated state (e.g.,  FIG. 6B ). Force (F) may be applied to base portion  146  when button  108  is in an actuated state by providing the force (F) applied to top surface  114  of button  108  through button  108  and second support  158 , respectively. That is, when applying a force to base portion  146  to place button  108  in an actuated position, first support  144  may no longer displace or distribute the force (F) through its respective components (e.g., bottom ridge,  148 , top ridge  102 ), as discussed with respect to  FIG. 6B . Rather, as shown in  FIG. 6C , tactile dome  162  may collapse and become substantially flat, such that the force applied to button  108  may be transferred from contact portion  160  to second support  158  without tactile dome  162  aiding in the distribution of the force (F) to first support  144 . Where the force (F) is applied to base portion  146  via second support  158 , base portion  146  may deflect or deform. More specifically, the segment (e.g., center) of base portion  146  positioned in alignment with second support  158  may substantially deflect or deform as a result of: the force (F) being applied through button  108  and second support  158 , the thickness of base portion  146  and/or the distance from sidewalls  112  of housing  102 . 
     As shown in  FIG. 6C , the deflection or deformation of base portion  146  may cause a change in the thickness (ΔT) of base portion  146  of housing  102 . That is, the thickness (T) of base portion  146  may no longer be uniform (e.g.,  FIGS. 6A and 6B ) because of the force applied by second support  108 , and may ultimately cause a change in the thickness (ΔT) of the segment of base portion  146  positioned above sensing component  164 . In deforming base portion  146  when button  108  is in an actuated state, piezoelectric sensor  166  (e.g., sensing component  164 ) may also be deformed. That is, as a result of base portion  146  deforming from the force (F) being applied during an actuated state of button  108 , piezoelectric sensor  166  (e.g., sensing component  164 ) may deformed by base portion  146 , and may send an electrical signal to a distinct component of electronic device  10  via wires  168 . As showing in  FIG. 6C , the deformation of base portion  146  may cause a similar deformation in piezoelectric sensor  166 . 
     Additionally, as shown in  FIG. 6C , when button  108  is in an actuated state, top surface  114  may be positioned substantially below top surface  106  of housing  102 . That is, in an actuated state, top surface  114  of button  108  may be temporarily out of planar alignment with top surface  106  of housing  102 . Furthermore, where button  108  is in an actuated state and displaced within opening  104  of housing  102 , engagement components  130 , and specifically clips  132 , of button  108  may be displaced even further when compared to button  108  in a partially actuated state. That is, as shown in  FIG. 8 , clips  132  may no longer contact underside surface  142  of apertures  110 , and may be positioned even further from underside surface  142  when compared to button  108  in a partially actuated state, as shown in  FIG. 6B . 
     Once the force (F) is no longer being applied to button  108 , waterproof button assembly  100  may return to an unactuated state (e.g.,  FIG. 6A ). More specifically, after the force (F) is removed from top surface  114  of button  108 , base portion  146 , tactile dome  162  and/or piezoelectric sensor  166  may return to their original configuration (e.g., no deformation, deflection or displacement), and may aid in displacing button  108  back to its original position. For example, substantially flat tactile dome  162  in the unactuated state may return to its original configuration (e.g., dome) when the force (F) is removed. In returning to its original configuration, tactile dome  162  may push button  108  toward top surface  106  of housing  102  until clips  132  (e.g., engagement components  130 ) contact underside surface  142  of opening  104 . Once clips  132  contact underside surface  142  again, button  108  may be held in opening  102  via clips  132  positioned within opening  102  and top surface  114  of button  108  may be in planar alignment with top surface  106  of housing  102 . 
     Turning to  FIGS. 7-8D , a method for assembling waterproof button assembly  100  may now be discussed. Specifically,  FIG. 7  is a flowchart depicting one sample method  900  for assembling waterproof button assembly  100 .  FIGS. 8A-8D  may depict a side cross-sectional view of waterproof button assembly  100  undergoing method  700 , as depicted in  FIG. 7 . It is understood that similarly numbered components may function in a substantially similar fashion. Redundant explanation of these components has been omitted for clarity. 
     In operation  702 , the plurality of clips  132  (e.g., engagement components  130 ) may be coupled to distal ends  124 ,  126  of button  108 . As shown in  FIG. 8A , and discussed above, each of the plurality of clips  132  may be slidingly engaged to one of the plurality of grooves  122  of button  108  and may be substantially free to move distally while slidingly engaged to button  108 . In operation  702 , as shown in  FIG. 8A , clips  132  may extend distally beyond distal ends  124 ,  126  of button  108  during the coupling process. Also discussed above, clips  132  may rest upon contact surface  140  of shelf portion  128  to substantially prevent clips  132  from rotating within grooves  122  of button  108 . 
     In operation  704 , the plurality of clips  132  may be compressed into button  108 . As shown in  FIG. 8B , a compression force (F comp ) may be applied to each clip  132  to move clips  132  toward center portion  136  of button  108 . As discussed herein, as clips  132  move toward center portion  136 , ends  138  of clips  132  may contact angled surface  134  of center portion  136  and may temporarily increase the width of clips  132 . In compressing clips  132  into button  108 , clips  132  may no longer extend beyond distal ends  124 ,  126 . That is, the clips  132  may be compressed to be in substantial alignment with distal ends  124 ,  126  of button  108 . As such, when clips  132  are in a compressed state, clips  132  may not extend the width of button  108  beyond the width of opening  104  of housing  102 . The compressing of the plurality of clips  132  in operation  704  may further including temporarily maintaining clips  132  in a compressed position. That is, after clips  132  are compressed into button  108 , clips  132  may be held in the compressed state until further processes of assembling waterproof button assembly  100  are completed, as discussed herein. 
     In operation  706 , button  108  and the plurality of compressed clips  132  may be inserted into housing  102 . As shown in  FIG. 8C , button  108 , including compressed clips  132  may be inserted into housing  102  while clips  132  remain compressed. That is, button  108  and clips  132  may be inserted through opening  104  formed through top surface  106  of housing  102 . Lower portion  120  may be inserted into opening  104  first, such that clips  132  may be temporarily positioned within opening  104  of housing  102  and top surface  114  of button  108  may be temporarily positioned substantially above top surface  106  of housing  102 . As shown in  FIG. 8C , during the insertion process, clips  132  may slightly extend distally from button  108  to contact sidewalls  112  of opening  104  of housing  102 . Although, clips  132  may contact sidewalls  112  of opening  104  during the insertion process, clips  132  and/or sidewalls  112  of opening  104  may not substantially prevent button  108  from being completely inserted into opening  10 . That is, clips  132  may contact sidewalls  112  during the insertion of button  108  and clips  132  into housing  102 , and clips  132  may slidingly move along sidewalls  112  of opening  104  as button  108  is inserted into housing  102 . 
     In operation  708 , the plurality of clips  132  of button  108  may be extended within housing  102 . As shown in  FIG. 8D , each of the plurality of clips  132  may extend distally from lower portion  120  of button  108 , and may extend beyond distal ends  124 ,  126  of button  208 . As discussed herein, when clips  132  of button  108  extends within housing  102 , each of the plurality of clips  132  may extend distally from button  108  into apertures  110  formed in sidewalls  112  of housing  102 . The extending of the plurality of clips  132  may further include applying a spring force (Fspring) to each of the plurality of clips  132  to displace the plurality of clips  132  distally from button  108 . That is, and as discussed herein with respect to  FIG. 3B , the plurality of clips  132  may extend within housing  102  as a result of the spring force applied to clips  132  via angled surface  134  of center portion  136 . More specifically, as a result of the compressing of the clips  132  in operation  904 , a spring force may be applied to each of the plurality of clips  132  as ends  138  of clips  132  move along angled surface  134  toward the center of button  108 . As button  108  is inserted into housing  102 , sidewalls  112  may retain clips  132  in a compressed state and overcome the spring force placed on the clips. However, as clips  132  of button  108  become aligned with apertures  110  of housing  102 , the spring force placed on clips  132  from angled surface  134  of center portion  136  may extend or displace the clips  132  distally, such that clips  132  extend distally beyond distal ends  124 ,  126  of button  108  and extend into aperture  110 . 
     In operation  710 , button  108  may be retained within housing  102  via the plurality of extended clips  132 . As shown in  FIG. 8D , the retaining of button  108  within housing  102  may include positioning at least a portion of each of the plurality of clips  132  of button  108  within one of the plurality of apertures  110  within housing  102 . More specifically, and as discussed herein with respect to  FIG. 4 , button  108  may be retained within housing  102  by positioning clips  132  within apertures  110  of housing  102 , where clips  132  may contact underside surface  142  of aperture  110 . By extending clips  132  into aperture  110  to contact underside surface  142 , button  108  may be retained in opening  104  of housing  102  and/or may be substantially prevented from being removed from housing  102  via opening  104 . 
       FIGS. 9A-14  illustrate side-cross sectional views of additional embodiments of waterproof button assembly. In one additional embodiment, as shown in  FIG. 9A , waterproof button assembly  900 A may include substantially similar components (e.g., housing  902 , button  908 , first support  944 , etc.) as waterproof button assembly  100  as shown in  FIGS. 2-4 . As such, redundant explanation of the similar components is excluded for clarity. As shown in  FIG. 9A , button  908  of waterproof button assembly  900 A may include a distinct shelf portion  928  of lower portion  920 . That is, lower portion  920  of button  908  may include distinct shelf portion  928  that may be coupled to the plurality of grooves  922  and/or upper portion  916  of button  908 . Distinct shelf portion  928  may be releasably coupled to button  908  of waterproof button assembly  900 A. In an example embodiment, as shown in  FIG. 9A , shelf portion  928  may be releasably coupled to button  908  via a plurality of mechanical fasteners  970 . Mechanical fasteners  970  may be positioned through bottom surface  972  of button  908  adjacent first support  944 . Mechanical fastener  970  may also extend partially through button  908  toward top surface  914  to couple shelf portion  928  to button  908 . Mechanical fasteners  970  used to releasably couple distinct shelf portion  928  to button  908  may include any conventional fastener including, but not limited to: screws, bolts, snap-fits, rivets, etc. 
     In another example embodiment where waterproof button assembly  900 B includes distinct shelf portion  928 , distinct shelf portion  928  may be mechanically fixed to button  908 . More specifically, as shown in  FIG. 9B , distinct shelf portion  928  may be fixed to bottom surface  972  of button  908 , adjacent first support  944 . Distinct shelf portion  928  may be mechanically fixed to button  908  using any conventional mechanical fixing technique including, but not limited to: welding, brazing, soldering, adhering, etc. 
     In an additional example embodiment, as shown in  FIG. 10 , engagement component  1030  of waterproof button assembly  1000  may include a press-fit protrusion  1074 . More specifically, engagement component  1030  may include a plurality of press-fit protrusions  1074  extending distally from each distal end  124 ,  126  of button  1008 . Press-fit protrusions  1074  may be a distinct component, and may be coupled to button  1008 . That is, each press-fit protrusions  1074  may be inserted and coupled to an opening  1076  formed in button  1008 . Press-fit protrusions  1074  of waterproof button assembly  1000  may include chamfered surface  1078  positioned on each distal end  1024 ,  1026  of button  108 . More specifically, as shown in  FIG. 10 , press-fit protrusions  1074  may include chamfered surface  1078  extending from each distal end  1024 ,  1026  of button  1008 . When inserting button  1008  into housing  1002  to form waterproof button assembly  1000 , chamfered surface  1078  of press-fit protrusion  1074  may aid in positioning button  1008  within opening  1404 . That is, when inserting button  1008  into opening  1004  of housing  1002 , chamfered surface  1078  of press-fit protrusion  1074 , which includes a width greater than the width of opening  1004  positioned adjacent top surface  1006 , may include an angle to button  1008  to be pressed or snapped into opening  1004 . 
     As shown in  FIG. 10 , press-fit protrusion  1074  may include a contact edge  1080  positioned adjacent chamfered surface  1078 . Contact edge  1080  may be configured to contact underside surface  1042  of aperture  1010  of housing  1002 . That is, and similarly discussed with respect to clips  132  in  FIG. 4 , at least a portion of each of the plurality of press-fit protrusions  1074  (e.g., contact edge  1080 ) may be positioned within one of the plurality of apertures  1010  in sidewall  1012  of housing  1002  for retaining button  1008  in housing  1002 . Contact edge  1080  may contact underside surface  1042  of opening  1010  to retain button  1008  within housing  1002 . In comparison to  FIG. 4 , apertures  1010  formed in sidewalls  1012  of housing  1002  may be formed in the majority of housing  1002 . That is, the plurality of apertures  1010  may be formed in the majority of sidewalls  1012  of opening  1004 , such that a portion of press-fit protrusions  1074  (e.g., chamfered surface  1078 , contact edge  1080 ) and first support  1044  may be positioned within apertures  1010  of housing  1002 . 
     In other example embodiments, as shown in  FIGS. 16 a  and 16 b   , waterproof button assembly  1600  may include housing  1602  having a removable base plate  1682  forming base portion  1646 . More specifically, housing  1602  may include a distinct, removable base plate  1682  which may be coupled to sidewalls  1612  to form base portion  1646  of housing  1602 . Removable base plate  1682  may be releasably coupled or mechanically fixed to sidewalls  1612  using any conventional fastener or coupling technique, discussed herein. Where housing  1602  includes removable base plate  1682 , opening  1604  may extend completely through housing  1602 . Including removable base plate  1682  may aid in the inserting of button  1608   a ,  1608   b  into opening  1602 . More specifically, button  1608   a ,  1608   b  may be inserted into opening  1604  of housing  1602  via opening covered by removable base plate  1682 , prior to coupling removable base plate  1682  to sidewalls  1612  to form housing  1602 . As a result of removable base plate  1682 , button  1608   a ,  1608   b  may not need to be inserted through opening  1604  adjacent top surface  1606  of housing  1602 , and ultimately may or may not require engagement components  1630  (e.g., clips, snap-fit protrusions  1074 ) that must fit through opening  1604  via top surface  1606 . 
     For example, as shown in  FIG. 11A , button  1108 A may include a plurality of distinct press-fit protrusions  1174  that may be mechanically fastened or releasably coupled to button  1108   a . Button  108   a  of  FIG. 11A  may be inserted into opening  1104  of housing  1102  adjacent top surface  1106  or inserted into opening  1104  opposite top surface  1106 , that may be subsequently covered by removable base plate  1182 . Conversely, in  FIG. 11B , button  1108 B may be a single component. More specifically, button  1108 B and the plurality of engagement components  1130  may be a single, integral component. Button  1108 B may include substantially rigid, polygonal engagement components  1130  that are integral with button  1108 B, and may include a width wider than a portion of opening  1104  positioned adjacent top surface  1106  of housing  1102 . As a result of the configuration of button  1108 B and engagement components  1130  being a single, integral piece, button  1108   b  of  FIG. 11B  may be inserted through opening  1104  opposite top surface  1106 , and may be positioned within housing  1102  adjacent top surface  1106 . Once button  1108   b  may be positioned within housing  1102  via opening  1104 , removable base plate  1182  may be coupled or fixed to housing  1102 . 
     In additional embodiments, as shown in  FIGS. 12-14 , sensing component  164  may be configured as a variety of distinct, conventional sensing components. A brief explanation of each of the variety of distinct, conventional sensing components may be provided for clarity. For example, in an embodiment of  FIG. 12 , sensing component  1264  may include a conventional optical sensor. Optical sensor (e.g., sensing component  1264 ) may include a laser or light emitter component  1284  positioned within button  1208  of waterproof button assembly  1200 . Laser or light emitter component  1284  may be configured to provide a light source that may substantially light opening  1204  of waterproof button assembly  1200 . Optical sensor, as shown in  FIG. 12 , may also include a photodiode component  1286  positioned below housing  1202 . More specifically, optical sensor forming sensing component  1264  may include photodiode component  1286  positioned below base portion  1246 , and outside of housing  1204 . In an unactuated state, the light emitted by light emitter component  1284  may substantially light opening  1204  and may also shine through tactile dome  1262  to photodiode component  1286 . The light of light emitter component  1284  may shine through glass or another clear material (not shown) positioned within base portion  1246  between button  1208  and photodiode component  1286 , forming a hermetic seal between opening  1204  and photodiode component  1286 . Conversely, during actuation of button  1208 , the light emitted by light emitter component  1284  may be substantially blocked from photodiode component  1286 . As a result of not being exposed to the light produced by light emitter component  1284 , photodiode component  1286  may recognize actuation of button  208  and may subsequently send an electrical signal to a component of electronic device  10  ( FIG. 1 ) via electrical wires (not shown). 
     In another example embodiment, as shown in  FIG. 13 , sensing component  1364  may include a conventional magnetic sensor. As shown in  FIG. 13 , sensing component  1364  of waterproof button assembly  1300  may include a magnet  1388  position within button  1308 , and a tactile (TAC) switch  1390  positioned adjacent magnet  1388 . Both magnet  1388  and TAC switch  1390  may be positioned within opening  1304  of waterproof button assembly  1300 . Magnetic sensor (e.g., sensing component  1364 ) may also include a reed switch  1392  positioned adjacent TAC switch  1390 . More specifically, as shown in  FIG. 13 , reed switch  1392  may be positioned adjacent TAC switch  1390 , outside of housing  1302 . In an unactuated state, reed switch  1392  may not complete a circuit with wires (e.g., not shown) electrically coupled to a component of electronic device  10  ( FIG. 1 ). However, in an actuated state of button  1308 , magnet  1388  may move toward TAC switch  1390  and reed switch  1392 , respectively, such that the magnet field adjacent reed switch  1392  may be increased. Where the magnetic field increases in the actuated state, reed switch  1392  may complete the electrical circuit for the wires (not shown) of sensing component  1364 , and may ultimately send an electrical signal to a component of electronic device  10  ( FIG. 1 ). 
     In a further embodiment, as shown in  FIG. 14 , sensing component  1464  may include a conventional TAC switch. As shown in  FIG. 14 , TAC switch may include a connector component  1494  positioned within housing  1402  and a plurality of electrical contacts  1496  positioned adjacent connector component  1494 . Electrical contacts  1496  may be formed within and/or through base portion  1446  of housing  1002  and may be electrically coupled to various components of the electronic device  10  ( FIG. 1 ) via wires (not shown). As shown in  FIG. 14 , electrical contacts  1496  may fit within, and be positioned through base portion  1446 , to form a hermetic seal within housing  1402  of waterproof button assembly  1400 . In an unactuated state, connector component  1494  may not contact electrical contacts  1496 , which may place the electrical contacts  1496  in an open position. When in an open position, no electrical current may flow between electrical contacts  1496 , which ultimately may result in no electrical current flowing to the component of electronic device  10  electrically coupled to electrical contacts  1496  of TAC switch of waterproof button assembly  1400 . Conversely, when button  1408  is actuated, connector component  1494  may contact both electrical contacts  1496 , placing the electrical contacts  1496  in a closed position. In a closed position, connector component  1494  may complete the electrical connection between the electrical contacts  1496 , such that an electrical current may flow between the electrical contacts  1496 , via the connector component  1494 , and ultimately to the component of the electronic device  10  ( FIG. 1 ). In a closed position, the component of the electronic device  10  electrically coupled to TAC switch may then be engaged or interacted with. 
     By utilizing the waterproof button assembly with an electronic device, as discussed herein with respect to  FIGS. 1-14 , the risk of exposure to harmful elements may be substantially eliminated. More specifically, by utilizing the waterproof button assembly discussed herein, the negative effects caused by water exposure to the electronic device may be substantially minimized or eliminated. By including an integral, single component housing and/or by placing at least a portion of the electrical components of a sensing component outside of the housing of the waterproof button assembly, water and other harmful elements may not come in contact with electrically sensitive portions (e.g., wires) of the sensing component. By providing that barrier and/or preventative configuration, only the mechanical portions (e.g., button, tactile dome, etc.) of the waterproof button assembly may be exposed to water and other harmful elements. As discussed herein, and as appreciated by one skilled in the art, because of the mechanical components configuration and/or material composition, the exposure to these elements may not negatively affect the operation or function of these components. As a result, the waterproof button assembly, as discussed herein, may provide continuous operation and function within an electronic device while also maintaining protection against the electronic device&#39;s exposure to harmful elements.
