Abstract

Claims (36)

1. An apparatus comprising:

a knob configured to be rotated;

a microphone;

volume control circuitry;

a speaker;

noise suppression circuitry, configured to decrease an amount of background noise received from the microphone; and

logic circuitry running code that instructs the logic circuitry to:

increase a volume of the speaker as the knob is rotated in a first direction such that the volume is increased in a continuous manner as the knob rotates; and

determine a rotation angle of the knob and increase a noise suppression level as the knob is rotated in the first direction such that the noise suppression level is increased after the knob is rotated past a first predetermined amount.

2. The apparatus of claim 1 wherein the code also instructs the logic circuitry to determine the rotation angle of the knob and increase the volume of the speaker as the knob is rotated in the first direction such that the volume is increased in the continuous manner as the knob is rotated until the knob is rotated past a second predetermined amount, then after the knob is rotated past the second predetermined amount the volume is increased instantaneously by at least 10 percent.

3. The apparatus of claim 2 wherein the first predetermined amount differs from the second predetermined amount.

4. The apparatus of claim 2 wherein the first predetermined amount is substantially equal to the second predetermined amount.

5. The apparatus of claim 2 wherein the volume is increased in a substantially linear manner as the knob is rotated in the first direction until the knob is rotated past the second predetermined amount.

6. The apparatus of claim 5 wherein the volume is increased by approximately 25% after the knob is rotated past the second predetermined amount.

7. The apparatus of claim 1 wherein no noise suppression takes place until the knob is rotated past the first predetermined amount.

8. An apparatus comprising:

a knob configured to be rotated;

a microphone;

volume control circuitry;

a speaker;

noise suppression circuitry, configured to decrease an amount of background noise received from the microphone; and

logic circuitry running code that instructs the logic circuitry to:

increase a volume of the speaker as the knob is rotated in a first direction such that the volume is increased in a continuous manner as the knob is rotated until the knob is rotated past a second predetermined amount, then after the knob is rotated past the second predetermined amount the volume is increased instantaneously by at least 10 percent;

determine a rotation angle of the knob and increase a noise suppression level as the knob is rotated in the first direction such that the noise suppression level is increased after the knob is rotated past a first predetermined amount;

wherein the volume is increased in a substantially linear manner as the knob is rotated in the first direction until the knob is rotated past the second predetermined amount; and

wherein no noise suppression takes place until the knob is rotated past the first predetermined amount.

9. A method comprising the steps of:

determining an amount a knob is rotated;

increasing a volume of a speaker as the knob is rotated in a first direction such that the volume is increased in a continuous manner as the knob rotates; and

increasing a noise suppression level as the knob is rotated in the first direction such that the noise suppression level is increased after the knob is rotated past a first predetermined amount.

10. The method of claim 9 wherein the volume is increased in the continuous manner as the knob is rotated until the knob is rotated past a second predetermined amount, then after the knob is rotated past the second predetermined amount the volume is increased instantaneously by at least 10 percent.

11. The method of claim 10 wherein the first predetermined amount differs from the second predetermined amount.

12. The method of claim 10 wherein the first predetermined amount is substantially equal to the second predetermined amount.

13. The method of claim 10 wherein the volume is increased in a substantially linear manner as the knob is rotated in the first direction until the knob is rotated past the second predetermined amount.

14. The method of claim 10 wherein the volume is increased by approximately 25% after the knob is rotated past the second predetermined amount.

15. The method of claim 9 wherein no noise suppression takes place until the knob is rotated past the first predetermined amount.
