Abstract

A mobile device is disclosed having an impact resistant input located in at least one of the corners. In the event that the mobile device is dropped and lands on the corner input, a shock-absorbing member absorbs the energy of impact to prevent failure to a contact or input cap of the corner input.

Claims

1. A mobile device with improved impact resistance upon an impact resulting from a drop, the mobile device comprising:

a housing having at least one corner; and

an input located proximate the at least one corner of the housing, the input including;

a contact operably connected to the mobile device,

an input cap accessible from an exterior of the mobile device, the input cap positioned over the contact and movable to manipulate the contact, and

a shock-absorbing member positioned between the contact and the input cap.

2. The mobile device of claim 1, wherein the contact is a dome switch.

3. The mobile device of claim 1, wherein the shock-absorbing member comprises a silicone rubber having a Shore hardness in a range of 50 to 60 Shore A hardness.

4. The mobile device of claim 1, wherein the shock-absorbing member is a rubber material having a Shore hardness in a range of 40 to 75 Shore A hardness.

5. The mobile device of claim 1, wherein the shock-absorbing member includes a securable portion securing the shock-absorbing member between the contact and the input cap and an absorbing portion positioned between the contact and the input cap.

6. The mobile device of claim 5, wherein the shock-absorbing member further includes a thin portion between the securable portion and the absorbing portion, the thin portion having a thickness less than the thickness of the absorbing portion.

7. The mobile device of claim 6, wherein the thin portion is elastically deflectable such that, when the input is operated, the securable portion and the absorbing portion are resiliently movable relative to one another.

8. The mobile device of claim 5, wherein the securable portion of the shock-absorbing member is secured to the housing to retain the shock-absorbing member between the contact and the input cap.

9. The mobile device of claim 8, wherein the securable portion of the shock-absorbing member includes a through hole formed therein, where a pin linked to the housing extends through the through hole, the pin being heat staked to secure the shock-absorbing member between the contact and the input cap.

10. The mobile device of claim 8, wherein the securable portion of the shock-absorbing member further includes a protrusion and the mobile device further includes a recess formed therein proximate the contact and wherein the protrusion on the securable portion of the shock-absorbing member is received in the recess formed proximate the contact to secure the shock-absorbing member between the contact and the input cap.

11. The mobile device of claim 8, wherein the securable portion of the shock-absorbing member includes a post extending therefrom that is received in a recess formed in the mobile device.

12. The mobile device of claim 1, wherein the mobile device includes a set of lockable inputs and the input located proximate the at least one corner of the housing is a lock key configured to enable and disable an operability of the set of lockable inputs.

13. The mobile device of claim 1, wherein the input is a mute key configured to mute a phone call on the mobile device.

14. The mobile device of claim 13, wherein the mute key is also configured to play and pause a playback of a media file on the mobile device.

15. The mobile device of claim 1, wherein the mobile device includes two inputs, each of the two inputs formed proximate to a corner of the housing.

16. The mobile device of claim 15, wherein the mobile device is configured such that when both of the two inputs are simultaneously pressed a function on the mobile device is performed.

17. The mobile device of claim 1, wherein the housing has at least two corners with a midpoint located therebetween and wherein the input is placed closer to one of the at least two corners than to the midpoint.

18. The mobile device of claim 1, wherein the housing includes two essentially planar surfaces that are essentially parallel with one another and have a set of peripheral side walls extending therebetween and wherein the at least one corner is formed along the set of peripheral side walls.

19. The mobile device of claim 1, wherein the input cap is a membrane.

20. A mobile device with improved impact resistance upon an impact resulting from a drop, the mobile device comprising:

a housing having at least one corner; and

an input located proximate the at least one corner of the housing, the input including;

a dome switch operably connected to the mobile device,

a membrane accessible from an exterior of the mobile device, the membrane positioned over the dome switch and movable to collapse the dome switch, and

a shock-absorbing member positioned between the dome switch and the membrane, the shock-absorbing member including a securable portion securing the shock-absorbing member between the dome switch and the membrane and an absorbing portion positioned between the dome switch and the membrane.
