Abstract

A radiotelephone device has a telephone handset-shaped housing for hand-held operation. The device includes electroacoustic transducers mounted at sound apertures in the housing, a keypad mounted between the apertures, and electronic circuitry. Video communication is accomplished by a video camera mounted in the housing and connected with the electronic circuitry and a liquid crystal display device mounted in the housing and connected to the electronic circuitry. Thus a radiotelephone is equipped with a video pickup device and a video display device.

Claims

1. A hand-held telephone comprising:

a hand-held housing having a front surface, at least two sound apertures disposed at the front surface and extending through the front surface into the hand-held housing;

at least two electroacoustic transducers mounted within the hand-held housing behind corresponding ones of the at least two sound apertures of the front surface of the hand-held housing and facing away from the hand-held housing;

a keypad mounted in the hand-held housing having keys which are accessible outside of the hand-held housing at the front surface of the hand-held housing;

a liquid crystal display mounted in the hand-held housing and having a display face directed away from the hand-held housing viewable at the front surface of the hand-held housing;

a video camera mounted in the hand-held housing directed away from the hand-held housing in the same direction as the display at the front surface of the hand-held housing; and

electronic circuitry disposed within said hand-held housing and connected to the at least two electroacoustic transducers, the keypad, the display and the video camera, for transmitting and receiving signals with an external telephone network.

2. The telephone according to claim 1, wherein the hand-held housing is a hand-held telephone handset shaped housing.

3. The telephone according to claim 2, wherein the at least two sound apertures are disposed at opposite ends of the front surface of the hand-held telephone handset-shaped housing.

4. The telephone according to claim 3, wherein the keypad is mounted between the at least two electroacoustic transducers.

5. The telephone according to claim 4, wherein the liquid crystal display is mounted adjacent the keypad between the at least two electroacoustic transducers.

6. The telephone according to claim 5, wherein the video camera is mounted between the display and one of the at least two electroacoustic transducers.

7. The telephone according to claim 6, wherein the signals transmitted and received by the electronic circuitry contain at least audio and visual information.

8. The telephone according to claim 2, wherein the keypad is mounted between the at least two electroacoustic transducers.

9. The telephone according to claim 8, wherein the liquid crystal display is mounted adjacent the keypad between the at least two electroacoustic transducers.

10. The telephone according to claim 9, wherein the video camera is mounted between the display and one of the at least two electroacoustic transducers.

11. The telephone according to claim 10, wherein the signals transmitted and received by the electronic circuitry contain at least audio and visual information.

12. The telephone according to claim 2, wherein the liquid crystal display is mounted adjacent the keypad between the at least two electroacoustic transducers.

13. The telephone according to claim 12, wherein the video camera is mounted between the display and one of the at least two electroacoustic transducers.

14. The telephone according to claim 13, wherein the signals transmitted and received by the electronic circuitry contain at least audio and visual information.

15. The telephone according to claim 2, wherein the video camera is mounted between the display and one of the at least two electroacoustic transducers.
