## Abstract

A device with a front face such as an operating face, including elements of the user interface of the device is provided. A major part of the front face is concave so that the front face is retracted and thereby protected from being scratched.

## Claims

### Claim 1

A device comprising an operating face of a front face of the device, wherein at least a substantial portion of the front face has a concave shape where long sides of the front face are straight and short sides of the front face are curved.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the front face has a first extent and a second extent and the operating face is concave in the second extent.

### Claim 3 (depends on 2)

A device according to claim 2, wherein the first extent is larger than the second extent and wherein the front face is concave in the direction of the second extent.

### Claim 4 (depends on 3)

A device according to claim 3, wherein the front face is a retracted surface that extends from edges of the front face that are substantially disposed in the direction of the first extent.

### Claim 5 (depends on 1)

A device according to claim 1, wherein the housing of the device comprises a curved panel with a concave front face and a convex rear face.

### Claim 6 (depends on 1)

A device according to claim 1, wherein the front face is an operating face.

### Claim 7 (depends on 1)

A device according to claim 1, wherein the operating face comprises elements of a user interface.

### Claim 8 (depends on 1)

A device according to claim 1, wherein the operating face includes a display screen, and wherein the surface of the display screen is concave.

### Claim 9 (depends on 8)

A device according to claim 8, wherein the surface of the display screen has a curvature that substantially matches the curvature of the front panel.

### Claim 10 (depends on 6)

A device according to claim 6, wherein the operating face includes a touch pad or touch screen, and wherein the surface of the touch pad or the touch screen is concave.

### Claim 11 (depends on 10)

A device according to claim 10, wherein the surface of the touch pad or the touch screen has a curvature that substantially matches the curvature of the front panel.

### Claim 12 (depends on 6)

A device according to claim 6, wherein the operating face includes a keypad, and wherein the surface of the keypad is concave.

### Claim 13 (depends on 12)

A device according to claim 12, wherein the surface of the keypad has a curvature that substantially matches the curvature of the front panel.

### Claim 14 (depends on 1)

A device according to claim 1, wherein the front surface is concave cylindrical.

### Claim 15 (depends on 1)

A device according to claim 1, further comprising a printed wired board that is curved so as to substantially match the curvature of the front face.

### Claim 16 (depends on 6)

A device according to claim 6, wherein the operating face includes a speaker outlet, and wherein the surface of the speaker outlet is concave.

### Claim 17 (depends on 16)

A device according to claim 16, wherein the surface of the speaker outlet has a curvature that substantially matches the curvature of the front panel.
