Abstract

An integrated portable phone and personal computing device has a hand-held body structure that allows the device to be comfortably held as a telephone receiver, yet is configured in such a way as not to decrease the computing capabilities of the device. The body structure provides for a display screen and input unit on a front surface of the device with a speaker and a microphone located on a side surface of the device. The arrangement for the body structure increases the useable surface area for both the display screen and input unit by providing for a combined display screen and input unit on the front surface. An activation key on the side of the unit inhibits data entry on the input unit when the device is being held as a telephone receiver without the need for a cover over the input unit. The arrangement for the body structure also decreases the overall width of the device by providing for structure that expands the width of a portion of the side surface around the speaker to a width that is larger and more comfortable as an ear piece for a telephone receiver.

Claims

1. An integrated portable telephone and personal computing device comprising:

a personal computer unit;

a telephone unit; and

a hand-held body structure housing both the personal computer unit and the telephone unit, the body structure including;

a front surface having a display screen and an input unit disposed on the front surface; and

a side surface having a microphone and a speaker disposed on the side surface and presenting a first width, the side surface including means for selectively expanding the width of at least a portion of the side surface proximate the speaker from a retracted position to an expanded position having a second width that is larger than the first width.

2. The device as claimed in claim 1 wherein the front surface has dimensions which are less than 10 cm by 17 cm and the side surface has a width less than 3 cm.

3. The device as claimed in claim 1 wherein the body structure further comprises:

a second side surface having at least one activation key means disposed on the second side surface for activating the input unit on the front surface.

4. The device as claimed in claim 1 wherein the first width is less than 3 cm and the second width is greater than 3.5 cm.

5. The device as claimed in claim 1 wherein the second width is between 20 to 50 percent greater than the first width.

6. The device as claimed in claim 1 wherein the expanding means comprises a pair of opposed spring-mounted members each of which extend from a respective edge of the side surface when in the expanded position to present the second width along the side surface and compress to the respective edge when in the retracted position.

7. The device as claimed in claim 1 wherein the expanding means comprises at least one member pivotally mounted on the side surface which extends beyond an edge of the side surface when in the expanded position to present the second width along the side surface and overlaps at least a portion of the side surface when in the retracted position.

8. The device as claimed in claim 1 wherein the display screen and input unit are integrated together as a pressure sensitive display panel.

9. The device as claimed in claim 1 wherein the side surface is obliquely angled.
