Abstract

An electronic device has a housing and a rotatable and translatable input mechanism. The housing has an aperture and the rotatable and translatable input mechanism has a shaft positioned at least partially within the aperture and a manipulation structure coupled to the shaft. The manipulation structure may be manipulated to rotationally and translationally move the shaft to provide rotational and translational input to the electronic device. A compressible seal is positioned in a gap between the housing and the rotatable and translatable input mechanism. The compressible seal may resist and/or prevent passage of contaminants into the aperture and/or obscure one or more internal components. The compressible seal may be configured to collapse or bend when the rotatable and translatable member translates.

Claims

1. An input mechanism assembly for an electronic device, comprising:

a rotatable and translatable member comprising;

a shaft positioned at least partially within an aperture of a housing; and

a manipulation structure coupled to the shaft and separated from the housing by a gap; and

a compressible seal positioned in the gap that resists passage of contaminants into the aperture and is configured to collapse when the rotatable and translatable member translates;

wherein

rotation of the rotatable and translatable member generates a first input to the electronic device;

translation of the rotatable and translatable member generates a second input to the electronic device;

the compressible seal comprises first and second arms positioned obliquely with respect to each other;

the first arm contacts the housing;

the second arm contacts the rotatable and translatable input member; and

the first and second arms are operable to move toward each other when the rotatable and translatable member translates.

2. The input mechanism assembly of claim 1, wherein the compressible seal is formed of at least one of silicone, polyurethane, hydrogenated nitrile butadiene rubber, or a fluoroelastomer.

4. The input mechanism assembly of claim 1, wherein:

the first arm has a first end and a second end;

the second arm has a third end and a fourth end;

the first and third ends are unconnected; and

the second and fourth ends are connected.

5. The input mechanism assembly of claim 1, wherein the compressible seal obscures at least one component that is at least one of formed of a different material than the manipulation structure or has a different finish than the manipulation structure.

6. The input mechanism assembly of claim 1, wherein rotation of the rotatable and translatable member is not transferred to the compressible seal.

7. The input mechanism assembly of claim 1, wherein the contaminants comprise liquid absent hydrostatic pressure.

3. (canceled)

8. A wearable electronic device, comprising:

a body including an aperture;

a crown comprising;

a knob;

a stem coupled to the knob and positioned at least partially within the aperture;

a tactile structure connected to the crown that is actuatable by translation of the crown; and

an elastomer Y-ring positioned between the crown and the body configured to bend when the crown translates to move the knob toward the body;

wherein

the elastomer Y-ring obscures at least one component with a different visual appearance than the knob; and

the elastomer Y-ring is operable to move freely of the body or the crown.

10. The wearable electronic device of claim 8, wherein rotation of the crown is transferred to the elastomer Y-ring.

11. The wearable electronic device of claim 8, further comprising a gasket positioned between the crown and the body that is shaped to define an indent into which the gasket is configured to expand when compressed.

12. The wearable electronic device of claim 8, wherein a shape of a force curve corresponding to actuation of the tactile structure by the translation of the crown is unchanged by the elastomer Y-ring.

13. The wearable electronic device of claim 8, wherein the elastomer Y-ring is configured to prevent light passage.

14. The wearable electronic device of claim 13, wherein a finish or a color of the elastomer Y-ring is configured to prevent light passage.

9. (canceled)

15-20. -20. (canceled)

an elastomer Y-ring positioned between the crown and the body configured to bend when the crown translates to move the knob toward the body;

wherein

the elastomer Y-ring obscures at least one component with a different visual appearance than the knob; and

wherein rotation of the crown is transferred to the elastomer Y-ring.

22. A wearable electronic device, comprising:

a body including an aperture;

a crown comprising;

a knob;

a stem coupled to the knob and positioned at least partially within the aperture;

a tactile structure connected to the crown that is actuatable by translation of the crown;

an elastomer Y-ring positioned between the crown and the body configured to bend when the crown translates to move the knob toward the body; and

a gasket positioned between the crown and the body that is shaped to define an indent into which the gasket is configured to expand when compressed;
