Abstract

The communication device includes a display unit, a communication unit, a speaker, a detecting unit, and a processing unit. The processing unit is used to receive and process audio signals. The speaker is used to reproduce the processed audio signals and emit sound waves. The detecting unit is used to detect the sound waves and acquire an intensity level. The processing unit is also used to compare the intensity level with a predetermined intensity level, disabling the display unit when the intensity level is greater than the predetermined intensity level, and enabling the display unit when the intensity level is smaller than or equal to the predetermined intensity level.

Claims

1. A communication device receiving a request from a communication apparatus, the communication device comprising:

a communication unit for being responsive to the request and a user instruction to establish a communication link between the communication device and the communication apparatus;

a display unit;

a processing unit for receiving audio signals from the communication apparatus when the communication link has been established, and processing the audio signals;

a speaker for reproducing the processed audio signals to emit sound waves; and

a detecting unit disposed adjacent to the speaker for detecting the sound waves, and measuring an intensity of the detected sound waves to acquire an intensity level, wherein the detected sound waves comprise the sound waves emitted directly to the detecting unit from the speaker and the sound waves reflected from an object back to the detecting unit when the sound waves emitted by the speaker reach the object and are reflected by the object;

wherein the processing unit further compares the intensity level with a predetermined intensity level, and disables the display unit when the intensity level is greater than the predetermined intensity level.

2. The communication device of claim 1, wherein the processing unit enables the display unit when the intensity level is smaller than or equal to the predetermined intensity level.

4. The communication device of claim 1, wherein the object is the user'"'"'s face.

5. The communication device of claim 1, wherein the communication device is a mobile phone.

6. The communication device of claim 1, further comprising:

a storage unit for storing a predetermined intensity level.

3. (canceled)

7. A method for automatically disabling a display unit of a communication device, the communication device receiving a request from a communication apparatus, the method comprising:

establishing a communication link between the communication device and the communication apparatus according to the request and a user instruction;

receiving audio signals from the communication apparatus when the communication link has been established and processing the audio signals;

reproducing the processed audio signals to emit sound waves;

detecting the emitted sound waves and measuring an intensity of the detected sound waves to acquire an intensity level, wherein the detected sound waves comprise the sound waves emitted directly to the detecting unit from the speaker and the sound waves reflected from an object back to the detecting unit when the sound waves emitted by the speaker reach the object and are reflected by the object; and

comparing the intensity level with a predetermined intensity level and disabling the display unit when the intensity level is greater than the predetermined intensity level.

8. The method of claim 7, further comprising:

enabling the display unit when the intensity level is smaller than or equal to the predetermined intensity level.

9. The method of claim 7, wherein the step of reproducing the processed audio signals to emit sound waves is implemented by a speaker, the step of detecting the emitted sound waves is implemented by a detecting unit, the detecting unit is disposed adjacent to the speaker.

10. The method of claim 7, wherein the object is a user'"'"'s face.

11. The method of claim 7, wherein the communication device is a mobile phone.

12. A system, comprising:

a communication apparatus; and

a communication device receiving a request from the communication apparatus, the communication device comprising;

a communication unit for establishing a communication link between the communication device and the communication apparatus according to the request and a user instruction;

a display unit;

a processing unit for receiving audio signals from the communication apparatus when the communication link has been established, and processing the audio signals;

a speaker for reproducing the processed audio signals to emit sound waves; and

a detecting unit for detecting the sound waves emitted by the speaker, and measuring an intensity of the detected sound waves to acquire an intensity level, wherein the detecting unit is disposed adjacent to the speaker, the detected sound waves comprise the sound waves emitted directly to the detecting unit from the speaker and the sound waves reflected from an object back to the detecting unit when the sound waves emitted by the speaker reach the object and are reflected by the object;

wherein the processing unit further compares the intensity level with a predetermined intensity level, and disables the display unit when the intensity level is greater than the predetermined intensity level.

13. The system of claim 12, wherein the processing unit enables the display unit when the intensity level is smaller than or equal to the predetermined intensity level.

15. The system of claim 12, wherein the object is the user'"'"'s face.

16. The system of claim 12, wherein the communication apparatus and the communication device are mobile phones.

17. The system of claim 12, wherein the communication device further comprises a storage unit for storing a predetermined intensity level.
