Abstract

A system and method for adjusting the volume level of a communications device in response to ambient noise. In one embodiment, ambient noise is sampled once and the volume of a speaker associated with the communications device is increased to, and maintained at, a level sufficient to overcome the ambient noise such that a user can easily carry on a conversation or hear what is being transmitted. In another embodiment, ambient noise is periodically sampled and the volume of the speaker is adjusted in response to the sampled ambient noise. The system and method provides enhanced user convenience and power saving advantages.

Claims

1. A method of controlling a volume of a speaker of a communications device during a call, comprising:

receiving a voice of a party to the call at a first microphone of the communications device;

sampling ambient noise at a second microphone of the communications device to detect an ambient noise level;

displaying a menu on the communications device that presents at least two different options for automatically controlling the volume of the speaker;

receiving a selection in the menu that selects an option for automatically controlling the volume of the speaker;

outputting conversation of another party to the call at the speaker;

when the ambient noise level exceeds a threshold noise level, then automatically controlling the volume of the speaker according to the option to compensate for the ambient noise level;

ending the call; and

assuming zero ambient noise at the second microphone upon placement of a subsequent call.

2. The method of claim 1, wherein the communications device comprises a mobile telephone.

3. The method of claim 1, further comprising selecting an initial volume level of the speaker.

4. The method of claim 1, further comprising enabling a button on the communications device to automatically adjust the volume of the speaker.

5. The method of claim 1, further comprising periodically re-sampling the ambient noise to re-adjust the volume of the speaker.

6. The method of claim 1, further comprising continuously re-sampling the ambient noise to re-adjust the volume of the speaker.

7. The method of claim 1, further comprising decreasing the volume of the speaker.

8. The method of claim 1, wherein the speaker is an ear piece.

9. The method of claim 1, further comprising setting a default volume level of the speaker.

10. The method of claim 1, further comprising resetting the volume of the speaker to an initial setting.

11. A method of compensating a volume of a speaker in response to ambient noise, comprising:

receiving a party'"'"'s voice during a call at a first microphone of a communications device;

sampling the ambient noise at a second microphone of the communications device;

selecting an initial volume level for the speaker;

outputting conversation of another party to the call at the speaker;

displaying a menu on the communications device that presents at least two different options for automatically controlling the volume of the speaker;

receiving a selection in the menu that selects an option for automatically controlling the volume of the speaker;

automatically increasing the volume of the another party output by the speaker according to the option in response to the ambient noise;

maintaining an increased volume of the speaker for a predetermined period of time;

ending the call; and

assuming zero ambient noise at the second microphone upon placement of a subsequent call.

12. The method of claim 11, wherein the speaker is associated with the communications device.

13. The method of claim 12, wherein the communications device is a mobile communications device.

14. The method of claim 13, wherein the mobile communications device is a mobile telephone.

15. The method of claim 11, further comprising resampling the ambient noise and adjusting the volume of the speaker in response to resampled ambient noise.

16. The method of claim 11, further comprising resetting the volume of the speaker to the initial volume level.

17. The method of claim 16, further comprising resetting the volume when at least one of a telephone call is completed and power to the communications device is turned off.

18. A mobile communications device, comprising:

a display screen, a speaker and two microphones housed in a body;

a first microphone of the two microphones, the first microphone receiving a party'"'"'s voice to a call;

a second microphone of the two microphones, the second microphone sampling ambient noise;

the speaker producing conversation of another party to the call;

a menu produced on the display screen, the menu offering two different options to automatically control a volume of the another party to the call produced by the speaker, the two different options comprising a first option to overcome a preset ambient noise level and a second option for dynamic compensation that samples the ambient noise;

means for adjusting the volume of the another party to the call produced by the speaker according to a selection from the menu

ending the call; and

assuming zero ambient noise at the second microphone upon placement of a subsequent call.

19. The device of claim 18, wherein the means for adjusting the volume periodically re-samples the ambient noise to re-adjust the volume of the speaker.

20. The device of claim 18, further comprising memory storing an initial volume level.

21. The device of claim 18, further comprising a button operable to enable the means for adjusting.

22. The device of claim 18, wherein the means for adjusting is operable to cause the volume of the speaker to decrease.

23. The device of claim 18, wherein the means for adjusting the volume continuously samples the ambient noise.

24. The device of claim 18, wherein the means for adjusting sets an initial volume level for the speaker.

25. The device of claim 24, wherein the means for adjusting resets the volume of the speaker to the initial volume level.
